Description

coating film

The present invention relates to a method for forming images such as personal computers, mobile terminals (PDA (personal digital assistant, personal digital assistant)), game machines, televisions (TVs), car navigation systems, touch panels, handwriting tablets, etc. A shape-shaped adhesive sheet laminate suitably used for a display device, and an adhesive sheet laminate suitable for forming a shape-shaped adhesive sheet laminate.

A touch panel type image display device is generally configured by combining a surface protection panel, a touch panel, and an image display panel (also collectively referred to as "components for an image display device"). In recent years, plastic materials such as acrylic resin boards or polycarbonate boards have been used in addition to tempered glass for surface protection panels of touch panel image display devices such as smartphones and tablet terminals. The peripheral part other than the face is printed in black. In addition, in the touch panel, a plastic film sensor is used together with a glass sensor, or a component called touch-on-a-chip (TOL) that integrates the function of the touch panel and the surface protection panel is used. , or use a surface-embedded or embedded component that integrates the touch panel function into the image display panel. In this kind of image display device, in order to further improve the image visibility, the gaps between the constituent members of the image display device are usually filled with transparent resins such as liquid adhesives, thermoplastic adhesive sheets, and adhesive sheets. The structure. In addition, in the field of image display devices centered on mobile phones and mobile terminals, in addition to thinner walls and higher precision, the diversification of designs has continued. Previously, black ink was usually printed in a frame shape on the periphery of the surface protection panel. However, with the diversification of the design, the frame-shaped concealed part began to be formed in a color other than black. When the concealed part is formed in a color other than black, since the concealment property is low, the height of the concealed part, that is, the printed part, tends to be higher than that of black. Therefore, for an adhesive sheet for bonding components having such a printed portion, it is required to fill each corner following a large printing step difference. Therefore, various methods for filling the printing level difference have been proposed previously. For example, in Patent Document 1, even if the adhered surface of the adhesive sheet has a level difference due to printing or the like, it can be adhered to the adhered surface without gaps and double-sided for a new image display device. An adhesive sheet discloses a double-sided adhesive sheet for an image display device, which is used to attach any two of the constituent members for an image display device selected from a surface protection panel, a touch panel, and an image display panel. A double-sided adhesive sheet bonded to an adherend, and at least one of the adherends has a step portion on the adhered surface of the double-sided adhesive sheet to be adhered, and the double-sided adhesive sheet is an adhesive bonded to the above-mentioned adhered surface The shape of the joint surface is formed along the surface shape of the above-mentioned adhered surface. Also, in Patent Document 2, a method for producing a double-sided adhesive sheet for bonding any two adherends selected from a surface protection panel, a touch panel, and an image display panel is disclosed. A method for manufacturing a double-sided adhesive sheet for a display device, characterized in that the double-sided adhesive sheet before lamination uses an adhesive composition with a gel fraction of less than 40%, and is shaped like the above-mentioned adherend Concave-convex shape of the mating surface is the same surface shape. prior art literature patent documents Patent Document 1: WO2014/073316 A1 Patent Document 2: WO2015/174392 A1

[Problems to be Solved by the Invention] In recent years, in the field of image display devices centered on mobile phones or mobile terminals, thinner walls and higher precision are required. Adhesive sheets are also required to be able to fill the unevenness of the surface of the adherend such as printing steps with high precision, and there is no situation where the adhesive material is exposed to the outside. As a countermeasure against this demand, as disclosed in the above-mentioned prior patent documents, it has been studied to form the surface shape of the adhesive sheet in conformity with the surface shape of the adherend in advance. In addition, in order to form the surface shape of the adhesive sheet in advance in conformity with the surface shape of the adherend as described above, the following method is assumed: an adhesive sheet laminated by laminating a release sheet on both sides of the adhesive sheet The body is press-molded to form a concave-convex shape that matches the concave-convex part of the surface of the adherend. However, as a result of trying to use an adhesive sheet laminate in which a normal release sheet is laminated on both sides of an adhesive sheet and actually carrying out the above method, the following problem was found: it is difficult to form and adhere to the surface of the adhesive sheet with high precision. Concave-convex shape corresponding to the concavo-convex part of the body surface. Therefore, the present invention proposes an adhesive sheet laminate that includes an adhesive layer and a covering portion that is laminated on one side of the adhesive layer in a peelable manner, and proposes an adhesive sheet that can be formed on the surface of the adhesive layer with high precision. A new adhesive sheet laminate having a concavo-convex shape conforming to the concavo-convex portion on the surface of an adherend, and a shaped adhesive sheet laminate using the same. [Technical means to solve the problem] The present invention proposes an adhesive sheet laminate, which is an adhesive sheet laminate comprising an adhesive layer and a covering portion I laminated on one side of the adhesive layer in a detachable manner Body, characterized in that: the storage elastic modulus E'(MA) of the coating part I at 100°C is 1.0×10 ⁶ to 2.0×10 ⁹ Pa, and the storage elastic modulus of the coating part I at 30°C E'(MB) is 5.0×10 ⁷ to 1.0×10 ¹⁰ Pa. Also, as a shaped adhesive sheet laminate using the above-mentioned adhesive sheet laminate, the present invention proposes a shaped adhesive sheet laminate in which the above-mentioned adhesive layer is provided with a concave portion, a convex portion, or Concave-convex part (referred to as "concave-convex part on the surface of the adhesive material layer"), and the above-mentioned coating part I is in close contact with one side surface of the front and the back of the above-mentioned adhesive material layer, and one side surface of the front and the back has a concave part, a convex part or a concave-convex part (referred to as "surface unevenness of the covering part"), and on the other side of the front and back that is opposite to one of the above-mentioned front and back, there is an unevenness that matches the surface unevenness of the above-mentioned adhesive material layer. Convex portion, concave portion, or concave-convex portion (referred to as “convex portion on the back surface of the covering portion”). [Effects of the Invention] According to the adhesive sheet laminate proposed by the present invention, for example, by heating the above-mentioned adhesive sheet laminate and then pressing the mold against the covering part I for molding, the surface of the adhesive layer can be formed at a height Accurately form the concave-convex shape that matches the concave-convex part of the surface of the adherend. In addition, since the covering part 1 can maintain shape retention under normal conditions, it is easy to handle, and because it is not too hard, it can suppress the formation of unintended unevenness in the adhesive layer. The shape-shaped adhesive sheet laminate proposed by the present invention has an uneven portion on the surface of the adhesive sheet on one side surface of the front and back of the adhesive layer, and the above-mentioned covering part I is in close contact with one of the front and back sides of the above-mentioned adhesive layer. As for the surface, one side surface of the front and the back is provided with a surface unevenness of the covering portion, and the other surface of the front and the back is provided with the back surface of the covering portion opposite to the one of the front and the back. As mentioned above, the shape-shaped adhesive sheet laminate proposed by the present invention has the above-mentioned covering part I closely attached to one side surface of the front and back of the above-mentioned adhesive material layer without gaps, and the above-mentioned covering part I can be peeled off. Laminated on one side surface of the front and back of the above-mentioned adhesive material layer, it can prevent dust, etc. The shape of the concave-convex portion on the surface of the adhesive material layer formed on the side surface of the back side absorbs moisture in the air and disintegrates, or dust, etc. adhere to the surface and the adhesive force is reduced.

Hereinafter, an example of an embodiment of the present invention will be described. However, the present invention is not limited by the following embodiments. [This adhesive sheet laminate] An adhesive sheet laminate (referred to as "the present adhesive sheet laminate"), which is an example of an embodiment of the present invention, is provided with an adhesive layer and laminated on the front side of the adhesive layer in a peelable manner as shown in FIG. An adhesive sheet laminate consisting of a covering part I formed on one side of the back surface and a covering part II formed by detachably laminated on the front side and the other side of the back side of the adhesive material layer. Here, the covering part II is arbitrary, and a structure in which the covering part II is not laminated can also be adopted. ＜Adhesive layer＞ The adhesive layer of this adhesive sheet laminate should be able to function as a double-sided adhesive sheet when the covering part I and covering part II are peeled off, and have a heat-melt property that softens or melts when heated. Can. The adhesive material layer preferably has a loss tangent tanδ (SA) of 1.0 or more at 100°C. Also, it is preferable that the loss tangent tan δ (SB) at 30° C. is less than 1.0. Here, the loss tangent tanδ means the ratio (G''/G') of the loss elastic modulus G'' to the storage elastic modulus G'. Since the temperature for thermoforming this adhesive sheet laminate is usually 70-120°C, if the loss tangent tanδ(SA) at 100°C is 1.0 or more, it becomes easy to form unevenness on the surface of the adhesive layer . In addition, if the loss tangent tanδ(SB) of the adhesive layer at 30°C is less than 1.0, the shape can be maintained under normal conditions, so it can be maintained on the surface of the adhesive layer with high precision to form the unevenness on the surface of the adherend. The state of the concave-convex shape. Generally, polymer materials have both viscous and elastic properties, and the loss tangent tanδ is above 1.0, and the larger the value, the stronger the viscous property. On the other hand, the loss tangent tanδ is less than 1.0, and the smaller the value, the stronger the elastic property. Therefore, by controlling the loss tangent tanδ of the adhesive layer at different temperatures, both formability and shape retention can be achieved. From this point of view, the loss tangent tanδ (SA) of the adhesive layer at 100° C. is preferably 1.0 or more, preferably 1.5 or more or 30 or less, and preferably 3.0 or more or 20 or less.

Also, the storage elastic modulus G'(SB) of the adhesive material layer at 30°C is preferably 1.0×10⁴ Above Pa. If the storage elastic modulus G'(SA) of the adhesive layer at 100°C does not reach 1.0×10⁴ Pa, sufficient formability can be obtained, so it is better. On the other hand, if the storage elastic modulus G'(SB) of the adhesive layer at 30°C is 1.0×10⁴ Pa or more is preferable from the viewpoint of shape stability after molding. From this point of view, the storage elastic modulus G'(SA) of the adhesive layer at 100°C is preferably less than 1.0×10⁴ Pa, which is further preferably 5.0×10¹ Above Pa or 5.0×10³ Pa or less, and more preferably 1.0×10² Above Pa or 1.0×10³ Below Pa. Accordingly, the storage elastic modulus G'(SA) of the adhesive layer at 100°C is more preferably 5.0×10¹ More than Pa and less than 1.0×10⁴ Pa, or 5.0×10¹ Above Pa and 5.0×10³ Pa or less, and more preferably 1.0×10² More than Pa and less than 1.0×10⁴ Pa, or 1.0×10² Above Pa and 5.0×10³ Below Pa, the best is 1.0×10² Above Pa and 1.0×10³ Below Pa. Also, from this point of view, the storage elastic modulus G'(SB) of the adhesive layer at 30°C is preferably 1.0×10⁴ Pa or more, and more preferably 2.0×10⁴ Above Pa or 1.0×10⁷ Pa or less, and more preferably 5.0×10⁴ Above Pa or 1.0×10⁶ Below Pa. Also, according to this, the storage elastic modulus G'(SB) of the adhesive layer at 30°C is more preferably 1.0×10⁴ Above Pa and 1.0×10⁷ Below Pa, or 1.0×10⁴ Above Pa and 1.0×10⁶ Below Pa, which is more preferably 2.0×10⁴ Above Pa and 1.0×10⁷ Below Pa, or 2.0×10⁴ Above Pa and 1.0×10⁶ Below Pa, the best is 5.0×10⁴ Above Pa and 1.0×10⁶ Below Pa. Here, the storage elastic modulus G'(SA) of the adhesive layer at 100°C and the storage elastic modulus G'(SB) of the adhesive layer at 30°C can be adjusted by adjusting the composition of the adhesive layer Components, gel fraction, weight average molecular weight, etc. are adjusted to the above-mentioned ranges. The temperature at which the loss tangent tanδ of the adhesive layer becomes 1.0 is preferably 50 to 150°C, more preferably 60°C or higher or 130°C or lower, and even more preferably 70°C or higher or 110°C or lower.

When the glass transition temperature (Tg) of the base resin of the adhesive layer is within the above range, adhesiveness can be imparted to the adhesive layer, and further, the temperature at which the loss tangent tanδ of the adhesive layer becomes 1.0 can be adjusted to 50 to 150°C. As a material for the adhesive layer, a conventionally known adhesive sheet can be used as long as it can be prepared to have a specific viscoelastic behavior.

When performances such as electrical characteristics and low refractive index are required, it is preferable to use the butadiene or isoprene-based copolymer of the above 2) as the base resin. When properties such as heat resistance and rubber elasticity in a wide temperature range are required, it is preferable to use the polysiloxane-based copolymer of the above 3) as the base resin. When performance such as re-peelability is required, it is preferable to use the polyurethane-based polymer of the above 4) as the base resin. As an example of the above-mentioned adhesive material layer, one formed of a resin composition containing a (meth)acrylic copolymer (a) as a base resin, a crosslinking agent (b), and a photopolymerization initiator (c) can be exemplified. Adhesive sheet. In this case, it is necessary to satisfy the above-mentioned viscoelastic properties in an uncrosslinked state, that is, a state before a three-dimensionally crosslinked network structure is formed. From this viewpoint, the gel fraction of the adhesive layer is preferably 40% or less. If the gel fraction of the adhesive layer is 40% or less, the bond between the molecular chains constituting the adhesive layer can be suppressed in an appropriate range, so it can have a moderate degree of flexibility when forming a shape-shaped adhesive sheet laminate. fluidity. From this point of view, the gel fraction of the adhesive layer is preferably 40% or less, particularly preferably 20% or less, particularly preferably 10% or less. Furthermore, the lower limit of the gel fraction of the adhesive material layer is not limited, and may be 0%.

(Photopolymerization initiator (c)) When crosslinking the acrylate polymer, if a crosslinking initiator (peroxide initiator, photopolymerization initiator) or a reaction catalyst (tertiary amine system Compounds, quaternary ammonium compounds, tin laurate compounds, etc.), are more effective. In the case of crosslinking by ultraviolet irradiation, it is preferable to prepare a photopolymerization initiator (c). Photopolymerization initiators (c) are roughly divided into two types according to the mechanism of free radical generation, roughly divided into: cleavage-type photopolymerization initiators that can break and decompose the single bond of the photopolymerization initiator itself to generate free radicals ; and the photoexcited initiator and the hydrogen donor and donor in the system form an excited complex, which can make the hydrogen transfer of the hydrogen donor and the hydrogen abstraction type photopolymerization initiator. Among them, the cleavage-type photopolymerization initiator decomposes into other compounds when free radicals are generated by light irradiation, and loses its function as a reaction initiator once excited. Therefore, if this intramolecular cleavage type is used as a photopolymerization initiator having an absorption wavelength in the visible light region, compared with the case of using a hydrogen abstraction type, after the adhesive sheet is crosslinked by light irradiation, light reaction A photopolymerizable initiator that remains in the adhesive composition as an unreacted residue is less likely to cause unexpected changes over time in the adhesive sheet or to promote crosslinking, so it is preferable. Moreover, since the coloring peculiar to a photopolymerizable initiator can also be selected suitably by becoming a reaction decomposition product and disappearing the absorption in the visible light region, it is preferable. On the other hand, when the photopolymerization initiator of the hydrogen abstraction type is irradiated with active energy rays such as ultraviolet rays to generate free radicals, it will not produce decomposition products such as the photopolymerization initiator of the cleavage type, so it is difficult to react after the reaction. Become a volatile component, which can reduce the damage to the adherend. Examples of the aforementioned cleavage-type photopolymerization initiator include: 2,2-dimethoxy-1,2-diphenylethan-1-one, 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy- 2-Methyl-1-phenyl-propan-1-one, 1-(4-(2-hydroxyethoxy)phenyl)-2-hydroxy-2-methyl-1-propan-1-one, 2-Hydroxy-1-[4-{4-(2-hydroxy-2-methyl-propionyl)benzyl}phenyl]-2-methyl-propan-1-one, oligo(2-hydroxy -2-methyl-1-(4-(1-methylvinyl)phenyl)acetone), methyl phenylglyoxylate, 2-benzyl-2-dimethylamino-1-(4- 𠰌linylphenyl)butan-1-one, 2-methyl-1-[4-(methylthio)phenyl]-2-𠰌linylpropan-1-one, 2-(dimethylamino )-2-[(4-methylphenyl)methyl]-1-[4-(4-𠰌linyl)phenyl]-1-butanone, bis(2,4,6-trimethylbenzene Formyl)-phenylphosphine oxide, 2,4,6-trimethylbenzoyldiphenylphosphine oxide, (2,4,6-trimethylbenzoyl)ethoxyphenylphosphine oxide Phosphine, bis(2,6-dimethoxybenzoyl) 2,4,4-trimethylpentylphosphine oxide, or derivatives thereof. Among them, bis(2,4,6-trimethylbenzoyl)-phenyl group is preferred in terms of decolorization after reaction as a decomposed product by the cleavage-type photopolymerizable initiator. Phosphine oxide, 2,4,6-trimethylbenzoyldiphenylphosphine oxide, (2,4,6-trimethylbenzoyl)ethoxyphenylphosphine oxide, bis(2,6 Acylphosphine oxide-based photoinitiators such as -dimethoxybenzoyl)2,4,4-trimethylpentylphosphine oxide. Furthermore, it is preferable to use 2,4,6-trimethylbenzoyldiphenyl Phosphine oxide, (2,4,6-trimethylbenzoyl)ethoxyphenylphosphine oxide, bis(2,6-dimethoxybenzoyl)2,4,4-trimethyl Amylphosphine oxide or the like is used as a photopolymerization initiator. The content of the photopolymerization initiator is not particularly limited. For example, 0.1 to 10 parts by mass, more preferably 0.2 parts by mass or more and 5 parts by mass or less, particularly preferably 0.5 parts by mass or more or 3 parts by mass with respect to 100 parts by mass of the (meth)acrylic copolymer Contain the following proportions. However, in terms of balance with other elements, it can also exceed this range. A photoinitiator can be used 1 type or in combination of 2 or more types. In addition to the above-mentioned ingredients, pigments such as pigments or dyes with near-infrared absorption characteristics, adhesion imparting agents, antioxidants, anti-aging agents, moisture absorbers, ultraviolet absorbers, silane coupling agents, natural products or synthetic materials can also be appropriately formulated as needed. Various additives such as resins, glass fibers or glass beads. (Layer Structure and Thickness of Adhesive Material Layer) The adhesive material layer may be a plurality of layers such as two layers or three layers in addition to a single layer. In addition, the adhesive material layer may have a base material layer (layer not having adhesive properties) as a core layer, and a structure in which layers including an adhesive material are laminated on both sides of the base material layer. In the case of such a structure, it is preferable that the base material layer which is a core layer has a material or characteristic which enables thermoforming of an adhesive sheet laminate. In addition, it is preferable that the adhesive material layer other than the base material layer has loss tangent tan δ (SA), loss tangent tan δ (SB), storage elastic modulus G'(SA), and storage elastic modulus G'(SB). above characteristics. The thickness of the adhesive layer is not particularly limited. Among them, the range of 20 μm to 500 μm is preferable. If it is this range, for example, if it is a thin adhesive material layer with a thickness of 20 micrometers, the adhesive sheet excellent in print level difference followability can be provided. Also, in the case of a thick adhesive material layer such as 500 μm in thickness, it becomes possible to suppress overflow of the adhesive material at the time of lamination by pre-shaping an amount corresponding to a printing step. Therefore, the thickness of the adhesive material layer is preferably 20 μm to 500 μm, more preferably 30 μm or more or 300 μm or less, and more preferably 50 μm or more or 200 μm or less. <Covering part I> This adhesive sheet laminate has the following covering part I as shown in FIG. Concave-convex sides are formed. The storage elastic modulus E'(MA) of the coating part I at 100°C is preferably 1.0×10⁶ ~2.0×10⁹ Pa. Since the temperature for thermoforming the adhesive sheet laminate is usually 70-120°C, if the storage elastic modulus E'(MA) at 100°C is 1.0×10⁶ ~2.0×10⁹ Pa, within the temperature range from plasticizing to flowing of the above-mentioned adhesive composition, the covering part I can also fully follow the concave-convex shape and deform, not only that, but also the adhesive material layer that can be squeezed by the covering part I during molding The surface of the surface is formed into the desired concave-convex shape with high precision, for example, in such a way as to avoid rounding of the corners. Previously, as a release film laminated on an adhesive sheet, a material with a high storage elastic modulus, in other words, a "harder" material was often used. The reason is that the characteristics required for the release film are mainly the protective adhesive layer and the release property. However, according to the research of the inventors of the present invention, it has been found that in the new application of thermoforming in the state where the release film is laminated on the adhesive sheet, when a new subject of thermoformability is required, it is difficult to rely on the previous release film. The above-mentioned physical characteristics possessed by the type film cannot meet the requirements. Therefore, after conducting detailed investigations on the phenomena that occur during thermoforming and the properties of the adhesive layer, it was found that setting properties that are different from those of release films that have been generally used so far can solve the new problem of thermoformability. beneficial. It was found that the above-mentioned problems can be solved by, inter alia, controlling the storage elastic modulus at a specific temperature to a specific range. From this point of view, the storage elastic modulus E'(MA) of the coating portion I at 100° C. is preferably 1.0×10⁶ ~2.0×10⁹ Pa, which is further preferably 5.0×10⁶ Above Pa or 1.0×10⁹ Pa or less, and more preferably 1.0×10⁷ Above Pa or 5.0×10⁸ Below Pa. Accordingly, the storage elastic modulus E'(MA) of the covering portion I at 100°C is more preferably 1.0×10⁶ ~1.0×10⁹ Pa, or 1.0×10⁶ ~5.0×10⁸ Pa, wherein, preferably 5.0×10⁶ ~2.0×10⁹ Pa, or 5.0×10⁶ ~1.0×10⁹ Pa, the best is 1.0×10⁷ ~1.0×10⁹ Below Pa, or 1.0×10⁷ ~5.0×10⁸ Pa. Also, the storage elastic modulus E'(MB) of the coating portion I at 30°C is preferably 5.0×10⁷ ~1.0×10¹⁰ Pa. If the storage elastic modulus E'(MB) of the coating part I at 30°C is 5.0×10⁷ ~1.0×10¹⁰ Pa, the shape retention can be maintained under normal conditions, so it is easier to handle, for example, it is easy to peel off. Not only that, but also because it is not too hard, it can suppress the formation of unintended unevenness in the adhesive layer. From this point of view, the storage elastic modulus E'(MB) of the coating portion I at 30° C. is preferably 5.0×10⁷ ~1.0×10¹⁰ Pa, which is further preferably 1.0×10⁸ Above Pa or 8.0×10⁹ Pa or less, and more preferably 1.0×10⁹ Above Pa or 5.0×10⁹ Below Pa. Accordingly, the storage elastic modulus E'(MB) of the covering portion I at 30°C is more preferably 5.0×10⁷ ~8.0×10⁹ Pa, or 5.0×10⁷ ~5.0×10⁹ Pa, wherein, and further preferably 1.0×10⁸ Pa～1.0×10¹⁰ Pa, or 1.0×10⁸ Pa～8.0×10⁹ Pa, the best is 1.0×10⁹ ~8.0×10⁹ Pa, or 1.0×10⁹ ~5.0×10⁹ Pa. In order to adjust the storage elastic modulus of the covering part I at 30°C and 100°C to the above, for example, the covering part I can be adjusted by adjusting the type of base resin, copolymer resin composition, weight average molecular weight, glass transition temperature, crystallinity, etc. The conditions of the material, and adjust the manufacturing conditions such as whether or not to stretch, forming conditions, and adjusting the stretching conditions in the case of stretching. However, it is not limited to these methods. Furthermore, it is preferable that the storage elastic modulus E'(MA) of the covering portion I at 100°C and the storage elastic modulus E'(MB) of the covering portion I at 30°C satisfy the following relational expression (1). (1)・・E'(MB)/E'(MA)≧2.0 If the storage elastic modulus E'(MA) of the covering part I at 100°C and the storage elastic modulus E'(MB) of the covering part I at 30°C satisfy the above relation (1), sufficient molding can be obtained Sex, so better. From this point of view, E'(MB)/E'(MA)≧2.0 is preferable, and 30≧E'(MB)/E'(MA) or E'(MB)/E' is more preferable (MA)≧3.0, especially 10≧E'(MB)/E'(MA) or E'(MB)/E'(MA)≧5.0. In order to adjust E'(MB) and E'(MA) to have the above relationship, for example, the type of base resin, copolymer resin composition, weight average molecular weight, glass transition temperature, crystallinity, etc. Conditions, and adjust the production conditions such as whether there is stretching, forming conditions, and adjusting stretching conditions in the case of stretching. However, it is not limited to these methods. Furthermore, it is preferable that the storage elastic modulus G'(SA) of the above-mentioned adhesive material layer at 100°C and the storage elastic modulus E'(MA) of the above-mentioned covering part I at 100°C satisfy the following relationship (2 ).

From this point of view, E'(MA)/G'(SA) is preferably 1.0×10³ ~1.0×10⁷ , which is preferably 5.0×10³ Above or 5.0×10⁶ Below, preferably 1.0×10⁴ Above or 1.0×10⁶ the following. Accordingly, E'(MA)/G'(SA) is better to be 1.0×10³ ~5.0×10⁶ , or 1.0×10³ ~1.0×10⁶ , and preferably 5.0×10³ ~5.0×10⁶ , or 5.0×10³ ~1.0×10⁶ , the optimum is 1.0×10⁴ ~5.0×10⁶ , or 1.0×10⁴ ~1.0×10⁶ . In order to adjust E′(MA) and G′(SA) to have the above-mentioned relationship, it is only necessary to adjust the characteristics of the adhesive material layer or the covering portion I. The characteristics of the adhesive layer can be achieved by, for example, adjusting the components of the composition constituting the adhesive layer, the gel fraction, the weight average molecular weight, and the like. In addition, as the characteristics of the covering part I, for example, the conditions of the material of the covering part I such as the type of the base resin, the copolymer resin component, the weight average molecular weight, the glass transition temperature, and the crystallinity can be adjusted, and the presence or absence of stretching and the molding conditions can be adjusted. , In the case of extension, adjust the manufacturing conditions such as extension conditions and adjust them. However, it is not limited to these methods. For the covering part I, the peeling force F(C) when the covering part I is peeled from the adhesive layer in an environment of 30° C. is preferably 0.2 N/cm or less. When peeling force F(C) is 0.2 N/cm or less, the said covering part I can be peeled easily from an adhesive material layer.

If the adhesive sheet laminate is heated at 100°C for 5 minutes and then cooled to 30°C, and the peeling force F(D) measured at 30°C is at the same level as the above peeling force F(C), even if the Even when the adhesive sheet laminate is thermoformed, the peeling force F(D) does not change, so the above-mentioned covering portion I can be easily peeled off from the adhesive layer. From this point of view, the peeling force F(D) is preferably 0.2 N/cm or less, more preferably 0.01 N/cm or more or 0.15 N/cm or less, and more preferably 0.02 N/cm or more or 0.1 N/cm or less. Furthermore, the covering portion I is preferably such that the absolute value of the difference between the peeling force F(C) and the peeling force F(D) is 0.1 N/cm or less. If the adhesive sheet laminate is heated at 100°C for 5 minutes and then cooled to 30°C, the absolute difference between the peel force F(D) measured at 30°C and the peel force F(C) under normal conditions If the value is 0.1 N/cm or less, the peeling force F(D) does not change even if the adhesive sheet laminate is thermoformed, so the covering portion I can be easily peeled off from the adhesive layer. From this point of view, the absolute value of the difference between the peeling force F(C) and the peeling force F(D) is preferably 0.1 N/cm or less, more preferably 0.08 N/cm or less, and even more preferably 0.05 Below N/cm. Furthermore, the peeling force F(C) and peeling force F(D) of the covering portion I can be adjusted by the type of the release layer formed on one side of the covering portion I, and the like. However, it is not limited to this method. As a configuration example of the covering part I, a configuration example including a coating base material layer and a release layer can be mentioned. By laminating the release layer on one surface of the covering base material layer, the covering portion I can be easily peeled off from the adhesive material layer. In this case, it is preferable that the covering base material layer has, as a main component, one resin or two or more resins selected from the group consisting of, for example, polyester, copolyester, polyolefin, and copolymerized polyolefin. The stretched or unstretched layer, that is, a single layer or a multilayer of a layer of a stretched or unstretched film containing these resins as a main component. Among them, the covering base material layer constituting the above-mentioned covering part I preferably has an extended film containing, for example, a copolymerized polyester, a polyolefin, or a copolymerized polyolefin as a main component from the viewpoint of mechanical strength or chemical resistance. Or monolayer or multilayer of layers of unstretched film. Specific examples of the above-mentioned copolymerized polyester include, for example, the use of isophthalic acid as a dicarboxylic acid, and cyclohexanedimethanol, 1,4-butanediol, diethylene glycol, etc. as a diol. Copolymerized polyethylene terephthalate formed by copolymerization. Specific examples of the polyolefin include α-olefin homopolymers, for example, propylene homopolymers and 4-methylpentene-1 homopolymers. Specific examples of the above-mentioned polyolefin copolymers include copolymers of ethylene, propylene, other α-olefins, vinyl monomers, and the like. The above-mentioned release layer is preferably a layer containing a modified polyolefin in addition to a release agent such as polysiloxane. Here, examples of the modified olefin constituting the release layer include resins whose main components are polyolefins modified with unsaturated carboxylic acids or anhydrides thereof, or silane-based coupling agents.

Esters of monoepoxides of derivatives and the above-mentioned acids, reaction products of polymers having groups capable of reacting with the acids in their molecules and acids, etc. Moreover, these metal salts can also be used. Among these, maleic anhydride can be used more preferably. Moreover, these copolymers can be used individually or in mixture of 2 or more types, respectively. In order to produce modified polyolefin-based resins, for example, the modified monomers may be copolymerized in advance at the stage of polymerizing the polymers, or the temporarily polymerized polymers may be graft-copolymerized with the modified monomers. . In addition, as the modified polyolefin resin, these modified monomers can be used alone or in combination, and the content is preferably 0.1% by mass or more, preferably 0.3% by mass or more, and more preferably 0.5% by mass.

And the other side of the back is formed by laminating the covering part II in a detachable manner. Thus, by laminating the cover portion II on the other side of the front and back of the adhesive material layer in a detachable manner, workability can be improved. However, it is also possible to adopt a configuration in which the covering portion II is not laminated. The material and configuration of the covering part II are not particularly limited as long as it is laminated on the other side of the front and back of the adhesive material layer in a detachable manner. Covering portion II may have, for example, the same laminated structure and material as the above-mentioned covering portion I, and in this case, may have the same thickness as the above-mentioned covering portion I, or may have a different thickness. If the covering part II has the same laminate structure and material as that of the covering part I, warpage can be prevented from occurring when the adhesive sheet laminate is heated. The covering part II can also adopt the same composition as the covering part I, but the storage elastic modulus E'(MA) at 100°C, the storage elastic modulus E'(MB) at 30°C, and the ratio of these (E '(MB)/E'(MA)), peeling force F(C), peeling force F(D), etc. are different from the coating part I. Furthermore, the covering part II may have a laminated structure and material different from the above-mentioned covering part I. For the covering part II, for example, a commonly used release film (also referred to as a "release film") can also be used. Specifically, for example, the storage elastic modulus E'(MC) at 100°C is 2.0×10⁹ ~1.0×10¹¹ As the material of Pa, for example, a biaxially stretched polyethylene terephthalate (PET) film or the like can be used. [Cover part I] As an example of the composition of the above-mentioned coating part I, a coating film is provided with a coating layer on one side of a copolymerized polyester film, and the storage elastic modulus E' at 100° C. is 1.5×10⁹ The coating film characterized by Pa or below (referred to as "the present coating film") will be described. If this coating film is used, for example, after heating the above-mentioned adhesive sheet laminate, pressing a mold against the coating film provided with a release coating layer for molding, it can be formed on the adhesive sheet. The surface is formed with a high-precision concave-convex shape that matches the concave-convex part of the surface of the adherend. In addition, since the coating film maintains shape retention under normal conditions, it is easy to handle, and because it is not too hard, it can suppress the formation of unintended unevenness on the adhesive sheet. ＜Copolymerized polyester film＞ The copolymerized polyester film constituting this coating film may be composed of a single layer or a laminated structure. For example, in addition to a 2-layer or 3-layer structure, as long as it does not exceed the gist of the present invention, it may also be 4 layers or 4 layers. The above multiple layers are not particularly limited. Also, for example, when a three-layer structure (surface layer/intermediate layer/surface layer) is adopted, any one layer or two or more layers of the surface layer or the intermediate layer may be used as a copolymerized polyester component, and the remaining The layer is constituted by a polyester component not containing a copolymerization component. In addition, the co-polymerized polyester film refers to a film obtained by cooling a molten polyester sheet extruded by an extrusion method, and stretching it as necessary. As the dicarboxylic acid component of the copolymerized polyester, terephthalic acid is preferred, in addition, oxalic acid, malonic acid, succinic acid, adipic acid, azelaic acid, sebacic acid, phthalic acid One or more kinds of known dicarboxylic acids such as dicarboxylic acid, isophthalic acid, naphthalene dicarboxylic acid, diphenyl ether dicarboxylic acid, and cyclohexanedicarboxylic acid are used as copolymerization components. Moreover, as a diol component, ethylene glycol is preferable, and other than that, propylene glycol, trimethylene glycol, tetramethylene glycol, hexamethylene glycol, 1,4-cyclohexane may be contained One or more kinds of known diols such as dimethanol, diethylene glycol, triethylene glycol, polyalkylene glycol, and neopentyl glycol are used as the copolymerization component. Among them, phthalic acid and isophthalic acid as dicarboxylic acid components, 1,4-cyclohexanedimethanol, 1,4-butanediol, diethylene glycol, etc. as diol components are more preferable. Copolymerized polyethylene terephthalate formed by random copolymerization. The content of the copolymerization component is preferably from 1 mol% to 50 mol%, more preferably from 3 mol% to 40 mol%, still more preferably from 4 mol% to 30 mol%. When the content of the copolymerization component is 1 mol% or more, a concave shape, a convex shape, or an uneven shape can be formed on the surface of the adhesive sheet when it is laminated with the adhesive sheet. On the other hand, by being 50 mol% or less, not only sufficient dimensional stability is obtained, but also generation of wrinkles during processing can be sufficiently suppressed. The melting point of the copolymerized polyester film is preferably designed so as to be within a range of preferably 260°C or lower, more preferably 200 to 255°C. Since the above-mentioned melting point is 260° C. or lower, sufficient strength can be obtained even if the heat treatment is performed at a temperature lower than the melting point of the copolymerized polyester film in the heat treatment step after stretching. From the viewpoint of improving film workability, it is preferable to contain particles in the copolymerized polyester film. Examples of particles include inorganic particles such as calcium carbonate, magnesium carbonate, calcium sulfate, barium sulfate, lithium phosphate, magnesium phosphate, calcium phosphate, lithium fluoride, aluminum oxide, silicon oxide, and kaolin; acrylic resin, guanamine resin, etc. Organic particles; Precipitated particles formed by granulating catalyst residues, but not limited to these. The particle diameter of these particles and the content in the copolymerized polyester film can be appropriately determined according to the purpose. The contained particles may be a single component, or two or more components may be used together. In addition, various stabilizers, lubricants, antistatic agents, etc. may be added appropriately. The average particle diameter of the particles contained in the copolymerized polyester film is preferably 0.1-5.0 μm. When the average particle diameter of the said particle|grains is less than 0.1 micrometer, the sliding property of a film becomes insufficient, and workability may fall. On the other hand, when the average particle diameter of the said particle|grains exceeds 5.0 micrometers, the smoothness of a film surface may be impaired. The content of the particles contained in the copolymerized polyester film is preferably 0.01 to 0.3% by weight. When content of the said particle|grains is less than 0.01 weight%, the sliding property of a film becomes insufficient, and workability may fall. On the other hand, when the content of the above particles exceeds 0.3% by weight, the smoothness of the film surface may be impaired. The method of adding particles to the copolymerized polyester film is not particularly limited, and known methods can be employed. For example, it can be added at any stage of polyester production, preferably at the stage of esterification, or it can be added in the form of slurry dispersed in ethylene glycol or the like after the transesterification reaction and before the polycondensation reaction starts to carry out the polycondensation reaction. In addition, it is possible to mix the slurry of particles dispersed in ethylene glycol or water with the polyester raw material by using a kneading extruder with a vent hole, or to mix the dried particles by using a kneading extruder. The method of blending with polyester raw materials, the method of precipitating particles in the polyester production process system, etc. are carried out. The intrinsic viscosity of the copolymerized polyester is usually 0.40-1.10 dl/g, preferably 0.45-0.90 dl/g, and more preferably 0.50-0.80 dl/g. If the limit viscosity is less than 0.40 dl/g, the mechanical strength of the film tends to be weakened. When the limit viscosity exceeds 1.10 dl/g, the melt viscosity becomes high and excessive load is applied to the extruder. situation. Next, although the manufacture example of a copolymerization polyester film is demonstrated concretely, it is not limited to the following manufacture example at all. Preferably, the following method is used: first, using the aforementioned co-polymerized polyester raw material, the melted sheet extruded from the die is cooled and solidified by a cooling roll to obtain an unstretched sheet. In this case, in order to improve the planarity of the sheet, it is necessary to improve the adhesion between the sheet and the rotating cooling drum, and the electrostatic application bonding method and/or the liquid coating bonding method can be preferably used. Then, it is preferred to stretch the obtained unstretched sheet at least in a uniaxial direction, more preferably biaxially stretched in a biaxial direction. For example, as biaxial stretching, in the case of sequential biaxial stretching, the above-mentioned unstretched sheet is stretched in one direction along the machine direction by a stretching machine of a roll or spoke type. The stretching temperature is usually 70-120°C, preferably 75-110°C, and the stretching ratio is usually 2.5-7.0 times, preferably 3.0-6.0 times. Next, extend in a direction perpendicular to the extending direction (machine direction) of the first stage. The stretching temperature is usually 70-170° C., and the stretching ratio is usually 3.0-7.0 times, preferably 3.5-6.0 times. Then, heat treatment is continued at a temperature of 150-270° C. under stretching or relaxation within 30%, to obtain a biaxially oriented film. In the biaxial stretching described above, a method of stretching in one direction in two or more stages may also be employed. In this case, it is preferable to carry out so that the stretching ratios of two directions may respectively become the said range finally. Moreover, simultaneous biaxial stretching can also be used for manufacture of a copolymerized polyester film. Simultaneous biaxial stretching is a method of simultaneously stretching and aligning the above-mentioned unstretched sheet in the machine direction and width direction at a temperature of usually 70-120°C, preferably 75-110°C, under temperature control. The elongation ratio is preferably 4 to 50 times in terms of area ratio, more preferably 7 to 35 times, and still more preferably 10 to 25 times. Then, heat treatment is continued under stretching or relaxation within 30% at a temperature of 150-250° C. to obtain a biaxially stretched film. For the simultaneous biaxial stretching device using the above-mentioned stretching method, conventionally known stretching methods such as a screw method, a pantograph method, and a linear drive method can be used. (coating layer) In this coating film, it is important to provide a coating layer on at least one side of the copolymerized polyester film. The coating layer is not particularly limited, and specific examples thereof include a release layer, an antistatic layer, an oligomer sealant layer, an easy-adhesive layer, and a primer layer. Among them, a release layer is more preferable in terms of producing an adhesive sheet laminate laminated with an adhesive sheet. Moreover, you may combine 2 or more types of functional layers mentioned above. As a specific example of the coating layer which comprises a coating film, the release layer is demonstrated below. Specifically, the types of resin used for the release layer include curable silicone resins, fluorine-based resins, and polyolefin-based resins, among which curable silicone resins are preferred. It may be a hardening silicone resin, or a type mainly composed of a hardening silicone resin. Within the scope of not detracting from the gist of the present invention, it may also be used by combining with urethane resin, ring Modified polysiloxane type obtained by graft polymerization of organic resins such as oxygen resin and alkyd resin, etc. As the type of curable silicone resin, any curing reactive type such as addition type, condensation type, ultraviolet curing type, electron beam curing type, and solvent-free type can be used. If specific examples are given, it can be illustrated: KS-774, KS-775, KS-778, KS-779H, KS-847H, KS-856, X-62-2422, X-62 manufactured by Shin-Etsu Chemical Co., Ltd. -2461, X-62-1387, X-62-5039, X-62-5040, KNS-3051, X-62-1496, KNS320A, KNS316, X-62-1574A/B, X-62-7052, X -62-7028A/B, X-62-7619, X-62-7213; YSR-3022, TPR-6700, TPR-6720, TPR-6721, TPR6500, TPR6501, UV9300, UV9425, XS56 manufactured by Momentive Performance Materials- A2775, XS56-A2982, UV9430, TPR6600, TPR6604, TPR6605; SRX357, SRX211, SD7220, SD7292, LTC750A, LTC760A, LTC303E, SP7259, BY24-468C, SP7248S, BY24-452, DKQ3- 202, DKQ3-203, DKQ3-204, DKQ3-205, DKQ3-210, etc. Furthermore, in order to adjust the peelability of a release layer, etc., you may use a peel control agent together. The hardening conditions for forming the release layer on the copolymerized polyester film are not particularly limited. When the release layer is provided by off-line coating, it is generally suitable to conduct heat treatment at 120-200° C. for 3-40 seconds, preferably at 100-180° C. for 3-40 seconds. Moreover, active energy ray irradiation, such as heat treatment and ultraviolet irradiation, can also be used together as needed. In addition, as an energy source for curing by active energy ray irradiation, conventionally known devices and energy sources can be used. The coating amount of the release layer (after drying) is generally 0.005 to 1 g/m in terms of coatability² range, preferably 0.005-0.5 g/m² The range, and more preferably 0.01 ~ 0.2 g/m² range. When the coating amount (after drying) does not reach 0.005 g/m² In this case, there are cases where it is difficult to obtain a uniform coating film due to the lack of stability in terms of coatability. On the other hand, at more than 1 g/m² On the other hand, in the case of thick coating, the coating film adhesion and curability of the release layer itself may decrease. As a method of providing a release layer on a copolymerized polyester film, conventionally known methods such as reverse gravure coating, direct gravure coating, roll coating, die coating, rod coating, and curtain coating can be used. The coating method. About the application method, there is an example described in "Applying method" (Maki Shoten, Yuji Harasaki, published in 1979). In addition, in order to provide a coating layer on the copolymerized polyester film, surface treatments such as corona treatment, plasma treatment, and ultraviolet irradiation treatment may be performed in advance. (coating film) The thickness of the coating film is usually 9 μm to 250 μm, preferably 12 μm to 125 μm, and more preferably 25 μm to 75 μm. When the above-mentioned thickness is less than 9 μm, the film tension becomes insufficient, and abnormalities such as wrinkles are likely to occur during slitting. On the other hand, if it exceeds 250 μm, for example, followability to a molded article having a curved shape may become insufficient. The storage elastic modulus E' of the coating film at 100°C is 1.5×10⁹ Below Pa, preferably 1.0×10⁹ Below Pa. By the above storage elastic modulus E' is 1.5×10⁹ Pa below, when it is laminated with an adhesive sheet, a concave shape, a convex shape, or a concavo-convex shape can be formed on the surface of the adhesive sheet. In order to make the storage elastic modulus E' in 100 degreeC satisfy|fill the said range, it can be satisfied by adjusting the kind and content of the copolymerization component contained in a copolymerization polyester film. On the other hand, the lower limit is not particularly limited, but is preferably 1.0×10⁷ Above Pa, more preferably 1.0×10⁸ Above Pa. The shrinkage rate of the coated film after heating at 120°C for 5 minutes is less than 3.0%, preferably less than 2.5%. Since the above-mentioned shrinkage rate is 3.0% or less, it has sufficient dimensional stability, so when it is laminated with an adhesive sheet, a concave shape, a convex shape, or a concave-convex shape can be formed on the surface of the adhesive sheet. Furthermore, since generation of wrinkles during processing can be suppressed, an adhesive sheet having a sufficient appearance can be produced without transferring wrinkles to the adhesive sheet. Among them, the shrinkage rate in the machine direction (MD) after heating at 120° C. for 5 minutes is preferably 3.0% or less, more preferably 2.5% or less. On the other hand, the lower limit is not particularly limited, but is preferably at least 0.1%, more preferably at least 0.5%. Also, the shrinkage rate in the direction (TD) perpendicular to the machine direction after heating at 120° C. for 5 minutes is preferably 1.0% or less, more preferably 0.8% or less. On the other hand, the lower limit is preferably -1.0% or more, more preferably -0.5% or more. From the viewpoint of preventing the contamination caused by the adhesion of the oligomer (cyclic trimer) to the mold during the forming process, it is preferable that the oligomer is free from coating after heat treatment (180°C, 10 minutes). The extraction amount on the surface of the layer is 1.0×10^-3 mg/cm² Below, preferably 5.0×10^-4 mg/cm² the following. When the extraction amount of the above-mentioned oligomer exceeds this range, the pollution caused by the adhesion of the oligomer to the mold during the molding process may become serious. As an example, in the processing of multiple continuous heat forming, the deposition of precipitated oligomers promotes mold contamination, so it is important to control the amount of oligomers precipitated during heating. For the above reasons, the less the amount of extraction of the above-mentioned oligomers, the better. [Manufacturing method of this adhesive sheet laminate] As an example of the manufacturing method of this adhesive sheet laminate, the method of sandwiching the adhesive composition between two covering parts I or II, and forming an adhesive layer using a lamination machine is mentioned, for example. Moreover, as another method, the method of applying an adhesive composition to the covering part I or II and forming an adhesive material layer is mentioned. However, it is not limited to this manufacturing method. As a method of coating an adhesive composition, conventionally known coating methods, such as reverse roll coating, gravure coating, bar coating, and knife coating, are mentioned, for example. [This shaped adhesive sheet laminate] Using this adhesive sheet laminate, a shaped adhesive sheet laminate 1 (referred to as "this shaped adhesive sheet laminate 1") in which concavo-convex shapes are formed on the surface of the adhesive layer can be produced as follows. As shown in FIG. 3 , the shape-shaped adhesive sheet laminate 1 can be manufactured as follows: it has an adhesive layer 2 and is laminated on one of the front and back sides of the adhesive layer 2 in a peelable manner. The covering part I formed on one side, and the covering part II formed by laminating on the other side of the front and back of the adhesive material layer 2 in a detachable manner, Adhesive material layer 2 has a concave portion, a convex portion or a concave-convex portion (referred to as “adhesive sheet surface concave-convex portion 2B”) on one side surface 2A of the front side and the back side, and the other side surface 2C of the front side and the back side is a flat surface, The covering part 1 is closely attached to the front and back side surfaces 2A of the above-mentioned adhesive sheet 2, and one side surface 3A of the front and back side is provided with a concave part, a convex part or a concave-convex part (referred to as "covering part surface concave-convex part 3B"), And on the back surface 3C of the sheet, there are convex, concave, or concave-convex portions that conform to the concave-convex portion 2B on the surface of the adhesive sheet, in other words, forming a fitting concave-convex portion (referred to as “protective sheet back convex-concave portion 3D”), The covering portion II includes a flat surface along the other side surface 2C of the front and back surfaces of the above-mentioned adhesive sheet 2 . Moreover, the other side surface 2C of the front and back can be made into a flat surface as shown in FIG. The shape-forming adhesive sheet laminate 1 having such a structure can be integrally formed by performing pressure forming, vacuum forming, pressure forming, or roll forming on the above-mentioned adhesive sheet laminate as shown in FIG. 2 . Method This adhesive sheet laminate is formed into a concavo-convex shape and manufactured. By manufacturing in the above manner, the uneven portion 2B on the surface of the adhesive sheet of the adhesive layer 2, the uneven portion 3B on the surface of the protective sheet of the covering portion 1, and the uneven portion 3D on the back surface of the protective sheet can be formed corresponding to each other at the same position to form unevenness. The adhesive material layer 2 can be used, for example as a double-sided adhesive sheet for bonding two image display device constituent members (each also referred to as an "adhered body") constituting the image display device. That is, the concave-convex part 2B on the surface of the adhesive sheet in the adhesive material layer 2 can be matched with the concave part, convex part or concave-convex part (referred to as "surface concave-convex part of the adherend") on the bonding surface of the above-mentioned adherend. Formed, preferably formed into the same contour shape. Thereby, the surface unevenness 2B of the adhesive sheet in the shape-shaped adhesive sheet laminate 1 can be fitted with the unevenness on the surface of the adherend in the constituent member of the image display device as the adherend. Here, as the above-mentioned image display device, for example, a device equipped with a liquid crystal display (liquid crystal display, LCD), an organic EL (electroluminescence, electroluminescence) display device (OLED (organic light emitting diode, organic light emitting diode) )), electronic paper, microelectromechanical system (microelectromechanical system, MEMS) display and plasma display (PDP), such as smart phones, tablet terminals, mobile phones, TVs, game consoles, personal computers, car navigation systems, ATM (automatic teller machine, automatic teller machine), fish detector, etc. But not limited to these. In addition, the image display device constituting member as an adherend refers to a member constituting such an image display device, for example, a surface protection panel, a touch panel, an image display panel, etc., and the present shape-shaped adhesive sheet laminate 1 For example, it can be used to bond any two adherends selected from a surface protection panel, a touch panel, and an image display panel. For example, it can be used to bond a surface protection panel and a touch panel, or a touch panel and an image display panel. However, the adherend is not limited to these. ＜Manufacturing method＞ Here, the method of manufacturing the shape-shaped adhesive sheet laminate 1 will be described in detail. As described above, as shown in FIG. 2 , the present adhesive sheet laminate 1 can be integrally formed with concavo-convex shapes by forming the above-mentioned present adhesive sheet laminate by heating, as shown in FIG. 2 . In this case, as the forming method, for example, pressure forming, vacuum forming, pressure forming, forming by rolls, forming by lamination, etc. may be mentioned. Among them, pressure molding is particularly preferable from the viewpoint of formability and workability. A more detailed specific example will be described. The adhesive sheet laminate is preheated by the heater, and the adhesive sheet laminate is transported to the pressure forming machine at the stage of heating to a specific temperature, and the concave-convex shape corresponding to the printed step shape of the adherend is used in advance. The mold is pressurized and cooled at the same time, so that the shape of the mold can be transferred to one side of the adhesive sheet laminate, and the shape-forming adhesive sheet laminate 1 with concavities and convexities formed on one side can be manufactured. At this time, the preheating of the adhesive sheet laminate is preferably heated to a temperature at which the adhesive layer softens, specifically, it is preferably heated to 70 to 120°C. The material of the mold used for concave-convex shaping is not particularly limited. For example, resin-based materials such as silicone resin and fluororesin, metal-based materials such as stainless steel or aluminum, and the like are mentioned. Among them, since high-precision formability is required for the unevenness of the adherend, it is particularly preferable to use a metal mold that can control the temperature during forming. In addition, the cooling after press working may be carried out after the mold is opened, or the mold may be cooled in advance, and the cooling may be performed while pressurizing. Furthermore, in the present invention, molding conditions such as pressing pressure and pressing time are not particularly specified, and may be appropriately adjusted according to the size or shape to be molded, the material used, and the like. In addition, after forming, it can also be cut using a Thomson blade, a rotary cutter, or the like. [Manufacturing method of the shaped adhesive sheet laminate] Then, for the covering part I which has an adhesive material layer and is laminated on one side of the adhesive material layer in a peelable manner, and forms a concave part, a convex part, or a concave-convex part on one side of the adhesive material (referred to as "adhesive A particularly preferred form of the method for manufacturing a shape-forming adhesive sheet laminate composed of "concave-convex parts" on the surface of the material layer will be described. The invention related to the present manufacturing method 1 and the present manufacturing method 2 described below proposes an adhesive material layer surface concave-convex part that can be formed on the surface of the adhesive material layer with high precision and conforms to the concave-convex part of the surface of the adherend, preferably A method for producing a novel shaped adhesive sheet laminate that can be produced continuously. As an example of an embodiment of the present invention, a novel method for manufacturing a shaped adhesive sheet laminate (referred to as "this manufacturing method 1") is proposed. The shaped adhesive sheet laminate system has an adhesive layer and can be The coating part I is laminated on one side of the adhesive material layer by peeling, and the surface of the adhesive material is formed with concave parts, convex parts or concave-convex parts (referred to as "adhesive material layer surface concave-convex part"). That is, the manufacturing method is characterized in that: it is equipped with an adhesive material layer and a coating part I laminated on one side of the adhesive material layer in a peelable manner, and the adhesive sheet laminate is heated, and the heated The manufacturing method of forming the adhesive sheet laminate and cooling it to produce a shape-shaped adhesive sheet laminate, and heating the adhesive sheet laminate, and the storage elastic modulus E'(MS) in the covering part I is 1.0× 10⁶ ~2.0×10⁹ Forming starts under the state of Pa, and the storage elastic modulus E'(MF) of the covering part I is 5.0×10⁷ ~1.0×10¹⁰ Forming is completed in the state of Pa. In this production method 1, a method for producing the above-mentioned novel shape-shaped adhesive sheet laminate is further proposed, which uses a cooled mold to form the heated adhesive sheet laminate. According to this manufacturing method 1, for example, by heating the above-mentioned adhesive sheet laminate, the covering part I starts forming in a specific state, and the covering part I finishes forming in a specific state, so that the surface of the adhesive layer can be formed with high precision. Form the concave-convex shape conforming to the concave-convex part of the surface of the adherend. Furthermore, when molding the heated adhesive sheet laminate, if the mold is cooled, the cooling can be performed simultaneously with the molding and the molding can be completed at the same time, so that the above-mentioned manufacturing method can be continuously carried out. ＜This production method 1＞ This production method 1 is a production method of a shape-shaped adhesive sheet laminate (referred to as "this production method") which is an example of this embodiment, including heating the adhesive sheet laminate described below (heating step), heating the heated A manufacturing method in which an adhesive sheet laminate is formed and cooled (forming and cooling steps). This manufacturing method 1 may include other steps as long as it includes the above-mentioned heating step and the above-mentioned forming and cooling steps. For example, steps such as a heat treatment step, a transfer step, a strip cutting step, and a cutting step may be included as needed. But not limited to these steps. (adhesive sheet laminate) The adhesive sheet laminate as a starting member in the production method 1 may include an adhesive layer and a covering portion I detachably laminated on one side of the adhesive layer, or may include other members. For example, as shown in FIG. 1 , an adhesive material layer, a covering portion I formed by detachably laminated on one side of the front and back sides of the adhesive material layer, and a detachably laminated cover portion I on the adhesive material layer can be exemplified. The other side of the front and back of the material layer is the adhesive sheet laminate of the covering part II. However, it is optional whether or not the covering portion II is provided, and a configuration in which the covering portion II is not laminated may also be adopted. In addition, the detail about the adhesive sheet laminated body is as above-mentioned. (heating step) In this production method 1, it is preferable to heat the above-mentioned adhesive sheet laminate so that the storage elastic modulus E'(M) of the covering portion I is 1.0×10⁶ ~2.0×10⁹ The state of Pa. If the storage elastic modulus E'(M) of the covering part I is in the above range, the covering part I can be deformed to a degree suitable for forming, and the surface of the adhesive material layer can be formed into a desired concave-convex shape with high precision. . From this point of view, it is preferable to set the storage elastic modulus E'(M) of the covering portion I to be 1.0×10 for heating the adhesive sheet laminate.⁶ ~2.0×10⁹ The state of Pa, which is further preferably set to 5.0×10⁶ Above Pa or 1.0×10⁹ The state below Pa, which is more preferably set to 1.0×10⁷ Above Pa or 5.0×10⁸ The state below Pa. Accordingly, it is more preferable to set the storage elastic modulus E'(M) of the covering portion I to be 1.0×10 for heating the adhesive sheet laminate.⁶ ~1.0×10⁹ Pa, or 1.0×10⁶ ~5.0×10⁸ state, wherein, and further preferably set to 5.0 × 10⁶ ~2.0×10⁹ Pa, or 5.0×10⁶ ~1.0×10⁹ The state of Pa, the best is set to 1.0×10⁷ ~1.0×10⁹ Pa, or 1.0×10⁷ ~~5.0×10⁸ state. Here, in order to adjust the storage elastic modulus E'(M) of the covering part I in the above-mentioned range by heating the adhesive sheet laminate, it is possible to adjust the composition according to the composition or gel content of the covering part I. Rate, weight average molecular weight, etc. are adjusted by adjusting the heating temperature. However, it is not limited to this method. Furthermore, it is even more preferable to heat the above-mentioned adhesive sheet laminate so that the storage elastic modulus E'(M) of the covering portion I is 1.0×10⁶ ~2.0×10⁹ Pa, and the storage elastic modulus G'(S) of the adhesive layer is less than 1.0×10⁴ The state of Pa. If the storage elastic modulus E'(M) of the covering part I is adjusted to the above range, the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G'(S) of the adhesive layer is less than 1.0 ×10⁴ Pa, sufficient formability can be imparted to the adhesive material layer. From this point of view, it is preferable to heat the adhesive sheet laminate so that the storage elastic modulus E'(M) of the covering part I is within the above range and the storage elastic modulus G'(S) of the adhesive layer does not reach 1.0×10⁴ The state of Pa, which is preferably set to 5.0×10¹ Above Pa or 5.0×10³ The state below Pa, which is preferably set to 1.0×10² Above Pa or 1.0×10³ The state below Pa. Accordingly, it is more preferable to heat the adhesive sheet laminate so that the storage modulus E'(M) of the covering part I is within the above range and the storage modulus G'(S) of the adhesive layer is 5.0×10¹ More than Pa and less than 1.0×10⁴ Pa, or 5.0×10¹ Above Pa and 5.0×10³ The state below Pa, which is more preferably set to 1.0×10² More than Pa and less than 1.0×10⁴ Pa, or 1.0×10² Above Pa and 5.0×10³ For the state below Pa, it is best to set it as 1.0×10² Above Pa and 1.0×10³ The state below Pa. Here, the storage elastic modulus G'(S) of the adhesive material layer can be adjusted by adjusting the heating temperature according to the composition, gel fraction, weight average molecular weight, etc. of the composition constituting the adhesive material layer. However, it is not limited to this method. Furthermore, it is more preferable to heat the adhesive sheet laminate so that the value of the loss tangent tanδ of the adhesive layer becomes 1.0 or more. Note that the loss tangent tan δ will be described below. When the value of the loss tangent tanδ of the adhesive material layer is 1.0 or more, it has flexibility to the extent that it can be molded, so it is preferable. From this point of view, it is particularly preferable to heat the adhesive sheet laminate so that the value of loss tangent tanδ of the adhesive layer becomes 1.0 or more, more preferably 1.5 or more or 20 or less, and even more preferably To make it above 3.0 or below 10. But the upper limit is not limited to this. In this manufacturing method 1, it is preferable to heat the adhesive sheet laminate so that the surface temperature of the covering portion I becomes 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive material layer is sufficiently softened, and the covering part I can be deformed sufficiently, and if it is 180°C or lower, the generation of wrinkles caused by heat shrinkage, or the formation of wrinkles caused by heat shrinkage can be suppressed. The disadvantages such as the decomposition of the adhesive material layer are caused, so it is better. From this point of view, it is preferable to heat the above-mentioned adhesive sheet laminate so that the surface temperature of the covering part I becomes 70 to 180° C., more preferably 75° C. It becomes 80 degreeC or more or 120 degreeC or less. As a method of heating the adhesive sheet laminate, for example, a method of heating the adhesive sheet laminate between upper and lower heating plates equipped with a heating body such as an electric heater inside, or directly sandwiching the adhesive sheet laminate The method of holding it, the method of using a heating roller, the method of immersing it in hot water, etc. However, it is not limited to these methods. (forming, cooling steps) In this step, the heated adhesive sheet laminate is formed as described above, and is cooled while forming the adhesive sheet laminate. That is, the adhesive sheet laminate in which the laminated adhesive layer and the covering portion I are integrated is directly molded. Thereby, the covering part I is formed by using a mold, and the adhesive material layer is also formed via this covering part I at the same time. In this step, the heated adhesive sheet laminate may be cooled after molding, or may be cooled simultaneously with molding. For example, by pressing with a cooled mold, forming and cooling can be performed simultaneously and ended at the same time. Thereby, this manufacturing method 1 can be implemented continuously as mentioned below. The molding method is not particularly limited as long as the adhesive sheet laminate can be integrally formed with concavo-convex shapes. For example, pressure forming, vacuum forming, pressure forming, forming by a roll, compression forming, forming by lamination, etc. are mentioned. Among them, pressure molding is particularly preferable from the viewpoint of formability and workability. The material of the mold is not particularly limited. For example, resin-based materials such as silicone resin and fluororesin, metal-based materials such as stainless steel or aluminum, and the like are mentioned. Among them, since high-precision formability is required for the unevenness of the adherend, it is particularly preferable to use a metal mold that can control the temperature during forming. The cooling method of the mold can adopt the usual cooling method. For example, cooling methods using water cooling or compressed air can be mentioned. For the mold, for example, as shown in Figure 2, a specific concave-convex shape is provided on the inner wall surface of at least one of the molds in the pair of open and close molds in advance, for example, in the bonding surface of the adherend that is provided with the adhesive layer. Concave-convex shape conforming to concave-convex part, convex part or concave-convex part, and the above-mentioned concave-convex shape can be transferred to the adhesive sheet by pressure forming, vacuum forming, pressure forming or roll forming of the adhesive sheet laminate using the mold The material is layered and shaped. In this step, preferably as described above, the storage elastic modulus E'(MS) of the coating portion I in the adhesive sheet laminate is 1.0×10⁶ ~2.0×10⁹ Forming begins in the state of Pa. Here, "starting molding" means, for example, in the case of molding using a mold, that the mold is closed, that is, the pressing of the adhesive sheet laminate starts using the mold. If the storage elastic modulus E'(MS) of the covering part I is 1.0×10⁶ ~2.0×10⁹ In the range of Pa, the covering part I can be deformed to a degree suitable for forming, and the surface of the adhesive material layer can be formed into a desired concave-convex shape with high precision. From this point of view, it is preferable that the storage elastic modulus E'(MS) of the covering portion 1 is 1.0×10⁶ ~2.0×10⁹ In the state of Pa, the formation of the adhesive sheet laminate is started, and it is more preferably 5.0×10⁶ Above Pa or 1.0×10⁹ Forming begins at a state below Pa, and it is more preferably 1.0×10⁷ Above Pa or 5.0×10⁸ Forming starts at a state below Pa. Accordingly, it is more preferable that the storage elastic modulus E'(MS) of the covering portion I is 1.0×10⁶ ~1.0×10⁹ Pa, or 1.0×10⁶ ~5.0×10⁸ In the state of Pa, the formation of the adhesive sheet laminate is started, and it is more preferably 5.0×10⁶ ~1.0×10⁹ Pa, or 5.0×10⁶ ~5.0×10⁸ Forming starts under the state of Pa, the best is 1.0×10⁷ ~1.0×10⁹ Pa, or 1.0×10⁷ ~5.0×10⁸ Forming begins in the state of Pa. Furthermore, it is more preferable that the storage elastic modulus E'(MS) of the covering portion I is 1.0×10⁶ ~2.0×10⁹ Pa, and the storage elastic modulus G'(SS) of the adhesive layer is less than 1.0×10⁴ In the state of Pa, the forming of the adhesive sheet laminate starts. If the storage elastic modulus E'(MS) of the covering part I is formed under the state of the above-mentioned range, the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G'(MS) of the adhesive layer SS) less than 1.0×10⁴ If molding is started in the state of Pa, molding can be performed in a state where the adhesive layer has more sufficient formability. From this point of view, it is more preferable that the storage elastic modulus E'(MS) of the covering part I is within the above range and the storage elastic modulus G'(SS) of the adhesive material layer is less than 1.0×10⁴ Forming starts under the state of Pa, and it is more preferable that the G'(SS) is 5.0×10¹ Above Pa or 5.0×10³ Forming begins at a state below Pa, and it is more preferably 1.0×10² Above Pa or 1.0×10³ Forming starts at a state below Pa. Accordingly, it is more preferable that the storage elastic modulus E'(MS) of the covering part I is in the above range and the storage elastic modulus G'(SS) of the adhesive layer is 5.0×10¹ More than Pa and less than 1.0×10⁴ Pa, or 5.0×10¹ Above Pa and 5.0×10³ Forming begins at a state below Pa, and it is more preferably 1.0×10² More than Pa and less than 1.0×10⁴ Pa, or 1.0×10² Above Pa and 5.0×10³ Forming begins at a state below Pa, the best is 1.0×10² Above Pa and 1.0×10³ Forming starts at a state below Pa. Moreover, it is preferable to start forming in the state where the surface temperature of the said covering part I is 70-180 degreeC. If the surface temperature of the covering part I is 70°C or higher, the adhesive material layer is sufficiently softened, and the covering part I can be deformed sufficiently, and if it is 180°C or lower, the generation of wrinkles caused by thermal shrinkage can be suppressed, or by Decomposition of the adhesive layer caused by heat and other disadvantages, so it is better. Therefore, it is preferable to start forming at a state where the surface temperature of the covering part I is 70 to 180° C., more preferably 75° C. or higher or 150° C. or lower, and more preferably 80° C. or higher or 120° C. below ℃. On the other hand, in this step, it is preferable that the storage elastic modulus E'(MF) of the above-mentioned covering part I is 5.0×10⁷ ~1.0×10¹⁰ Forming is completed in the state of Pa. Here, "completion of molding" means that the application of molding pressure to the adhesive sheet laminate is completed, and in the case of mold molding, it means that the mold is opened. If the storage elastic modulus E'(MF) of the above-mentioned covering part I is 5.0×10⁷ Above Pa and 1.0×10¹⁰ The range of Pa or less is preferable since the shape stability after molding is excellent. From this point of view, it is preferable that the storage elastic modulus E'(MF) of the above-mentioned coating portion I is 5.0×10⁷ ~1.0×10¹⁰ Forming is completed under the state of Pa, which is more preferably 1.0×10⁸ Above Pa or 8.0×10⁹ The forming is completed under the state of Pa or less, and it is more preferably 1.0×10⁹ Above Pa or 5.0×10⁹ Molding is completed in the state below Pa. Accordingly, in this step, it is more preferable that the storage elastic modulus E'(MF) of the above-mentioned covering portion I is, 5.0×10⁷ ~8.0×10⁹ Pa, or 5.0×10⁷ ~5.0×10⁹ The forming is completed under the state of Pa, among which, it is preferably 1.0×10⁸ ~8.0×10⁹ Pa, or 1.0×10⁸ ~5.0×10⁹ Forming is completed under the state of Pa, the best is 1.0×10⁹ ~8.0×10⁹ Pa, or 1.0×10⁹ ~5.0×10⁹ Forming is completed in the state of Pa. Furthermore, it is more preferable that the storage elastic modulus E'(MF) of the covering part I is in the above-mentioned range and the storage elastic modulus G'(SF) of the adhesive material layer is 1.0×10⁴ Molding is completed in the state of Pa or higher. If the molding is completed with the storage elastic modulus E'(MF) of the above-mentioned coating part I in the above-mentioned range, the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G' of the adhesive layer (SS) is 1.0×10⁴ When the forming is completed in the state of Pa or higher, the formed adhesive layer can maintain its shape. From this point of view, it is preferable that the storage modulus E'(MF) of the covering portion I is in the above range and the storage modulus G'(SF) of the adhesive layer is 1.0×10⁴ Forming is completed in the state above Pa, and it is more preferable that the storage elastic modulus G'(SF) of the adhesive material layer is 5.0×10⁴ Above Pa or 5.0×10⁷ Forming is completed at a state below Pa, and it is more preferably 1.0×10⁴ Above Pa or 1.0×10⁷ Molding is completed in the state below Pa. In addition, it is preferable to complete the molding in a state where the surface temperature of the above-mentioned covering portion I is less than 50°C. For example, in the case of press molding, it is preferable to open the mold in a state where the surface temperature is less than 50°C. If the surface temperature of the covering part I is less than 50°C, and the storage elastic modulus E'(MS) of the covering part I is 5.0×10⁷ ~1.0×10¹⁰ The range of Pa is preferable because it can suppress deformation when the molded body is taken out after molding, or warpage due to heat shrinkage of the covering part I. From this point of view, it is preferable to complete the molding when the surface temperature of the covering portion 1 is less than 50°C, especially preferably when the surface temperature is 0°C or higher or 45°C or lower, and especially preferably 0°C or higher. Molding is completed in a state where the temperature becomes 10°C or higher or 40°C or lower. Furthermore, it is preferable that the storage elastic modulus E'(MS) of the covering part I at the beginning of the above-mentioned forming and the storage elastic modulus E'(MF) of the covering part I at the end of the above-mentioned forming satisfy the following relational expression (1) . (1)・・E'(MF)/E'(MS)≧1.3 Here, if the storage elastic modulus E'(MS) of the covering part I and the storage elastic modulus E'(MF) of the covering part I at the end of the above-mentioned forming satisfy the above-mentioned relational expression (1), then at the beginning of forming It is preferably soft enough to be molded and hard enough to maintain the molded shape after the molding is completed. From this point of view, E'(MF)/E'(MS)≧1.3 is preferred, and 100≧E'(MF)/E'(MS) or E'(MF)/E' is further preferred. (MS)≧3.0, especially 50≧E'(MF)/E'(MS) or E'(MF)/E'(MS)≧5.0. However, the upper limit of E'(MF)/E'(MS) is not limited thereto. Also, it is preferable that the storage elastic modulus E'(MF) of the covering part I at the end of the above-mentioned forming and the storage elastic modulus G'(SF) of the adhesive material layer at the end of the above-mentioned forming satisfy the following relational expression (2) . (2)・・E'(MF)/G'(SF)≦1.0×10⁷ Here, if the storage elastic modulus E'(MF) of the covering part I at the end of the above-mentioned forming and the storage elastic modulus G'(SF) of the adhesive material layer at the end of the above-mentioned forming satisfy the above-mentioned relational expression (2), then The formed adhesive material layer can maintain the shape. From this viewpoint, it is preferable that E'(MF)/G'(SF)≦1.0×10⁷ , which is further preferably 1.0≦E'(MF)/G'(SF) or E'(MF)/G'(SF)≦5.0×10⁶ , which is further preferably 1.0×10¹ ≦E'(MF)/G'(SF) or E'(MF)/G'(SF)≦1.0×10⁶ . Although it is repeated, in this production method 1, the mold can be press-formed and cooled after opening the mold, or the mold can be cooled in advance and cooled while press-forming. If the mold is cooled in advance in this way, and the cooling is performed simultaneously with press molding, the molding and cooling can be completed at the same time. Thereby, the shape-shaped adhesive sheet laminate can be conveyed to the next step immediately after completion of shaping and cooling, and thus the shape-shaped adhesive sheet laminate can be continuously manufactured. In the case of cooling while molding the mold, the surface temperature of the mold is preferably 0 to 50°C. If the surface temperature of the mold is below 50°C, the shape of the adhesive sheet laminate can be fixed in a short period of time, and the precision of the molded body obtained can be good, and warpage accompanying heat shrinkage during the cooling process after molding can be suppressed. Better from this point of view. Therefore, the surface temperature of the mold is preferably 0 to 50°C, more preferably 10°C or higher or 40°C or lower, particularly preferably 15°C or higher or 30°C or lower. Furthermore, the conditions of press molding such as press pressure and press time are not particularly limited, and may be appropriately adjusted according to the size or shape to be formed, the material to be used, and the like. (Others) The shape-shaped adhesive sheet laminate obtained in the above forming and cooling steps can be wound up as it is, can also be heat-treated, and can also be cut into a specific size and shape. When cutting, the method of cutting using a Thomson blade, a rotary cutter, etc. is mentioned, for example. In this production method 1, it is preferable to continuously produce a shaped adhesive sheet laminate. For example, the adhesive sheet laminate may be conveyed to a heating unit such as a heater, and the conveyance may be stopped for a specified time in the heating unit for heating, or the heated adhesive sheet laminate may be conveyed to a molding machine after heating while conveying. In the forming unit, such as a forming mold, in the forming unit, for example, pressurized by a cooled mold, cooling is performed while forming, and then transferred to the next unit if necessary, and the shape-shaped adhesive sheet is continuously produced. laminated body. <This production method 2> As an example of an embodiment of the present invention, a method for producing a shaped adhesive sheet laminate (referred to as "this production method 2") is proposed. This shaped adhesive sheet laminate system has an adhesive material Layer and the coating part I laminated on one side of the adhesive material layer in a peelable manner, and form a concave part, a convex part, or a concave-convex part on one side of the adhesive material layer (referred to as "adhesive material layer surface concave-convex part") The characteristic of this manufacturing method is that it is to heat the adhesive sheet laminated body having the adhesive material layer and the covering part I laminated on one side of the adhesive material layer in a detachable manner, and use A method for manufacturing a shape-shaped adhesive sheet laminate by molding the heated adhesive sheet laminate with a mold, and heating the adhesive sheet laminate, starting when the surface temperature of the coating part I is 70-180°C After molding, the shape-forming adhesive sheet laminate was taken out from the mold after the surface temperature of the covering part I became less than 60°C. According to this production method 2, by heating the adhesive sheet laminated body, the molding starts in the state where the surface temperature of the covering part I is 70 to 180°C, and after the surface temperature of the covering part I becomes less than 60°C, it is removed from the mold. The shape-shaped adhesive sheet laminate is taken out, and, for example, a concave-convex shape that matches the concave-convex portion of the surface of the adherend can be formed on the surface of the adhesive layer with high precision. This production method 2 is a production method including the steps of heating the adhesive sheet laminate described below (heating step), forming and cooling the heated adhesive sheet laminate (forming, cooling step). This manufacturing method 2 may include other steps as long as it includes the above-mentioned heating step and the above-mentioned forming and cooling steps. For example, steps such as a heat treatment step, a transfer step, a strip cutting step, and a cutting step may be included as needed. But not limited to these steps. (Adhesive sheet laminate) The adhesive sheet laminate as a starting member in the production method 2 may include an adhesive layer and a covering portion I laminated on one side of the adhesive layer in a detachable manner, Other components may also be provided. For example, as shown in FIG. 1 , an adhesive material layer, a covering portion I formed by detachably laminated on one side of the front and back sides of the adhesive material layer, and a detachably laminated cover portion I on the adhesive material layer can be exemplified. The other side of the front and back of the material layer is the adhesive sheet laminate of the covering part II. However, it is optional whether or not the covering portion II is provided, and a configuration in which the covering portion II is not laminated may also be adopted. In addition, the detail about the adhesive sheet laminated body is as above-mentioned. (Heating step) In this step, the above-mentioned adhesive sheet laminate is heated so that the surface temperature of the covering portion I becomes 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive material layer is sufficiently softened, and the covering part I can be deformed sufficiently, and if it is 180°C or lower, the generation of wrinkles caused by heat shrinkage, or the formation of wrinkles caused by heat shrinkage can be suppressed. The disadvantages such as the decomposition of the adhesive material layer are caused, so it is better. From this point of view, it is preferable to heat the above-mentioned adhesive sheet laminate so that the surface temperature of the covering part I becomes 70 to 180° C., more preferably 75° C. It becomes 80 degreeC or more or 120 degreeC or less. Accordingly, it is more preferable to heat the above-mentioned adhesive sheet laminate so that the surface temperature of the covering part I becomes 70 to 150° C., or 70 to 120° C. 120°C, preferably 80 to 150°C, or 80 to 120°C. As a method of heating the adhesive sheet laminate, for example, a method of heating the adhesive sheet laminate between upper and lower heating plates equipped with a heating body such as an electric heater inside, or directly sandwiching the adhesive sheet laminate The method of holding it, the method of using a heating roller, the method of immersing it in hot water, etc. However, it is not limited to these methods. (Shaping and cooling step) In this step, it is preferable to start the molding of the adhesive sheet laminate while heating the surface temperature of the coating part I to 70 to 180° C. as described above. That is, it is preferable to directly form the adhesive sheet laminate in which the laminated adhesive layer and the covering portion I are integrated. Thereby, while forming the covering part I, the adhesive material layer can also be formed via this covering part I. In this step, the heated adhesive sheet laminate may be cooled after molding, or may be cooled simultaneously with molding. For example, by pressing with a cooled mold, forming and cooling can be performed simultaneously and ended at the same time. Thereby, this manufacturing method 2 can be implemented continuously as mentioned below. The molding method is not particularly limited as long as the adhesive sheet laminate can be integrally formed with concavo-convex shapes. For example, pressure forming, vacuum forming, pressure forming, forming by a roll (roll forming), compression forming, forming by lamination, etc. are mentioned. Among them, pressure molding is particularly preferable from the viewpoint of formability and workability. When molding is performed using a mold, the material of the mold is not particularly limited. For example, resin-based materials such as silicone resin and fluororesin, metal-based materials such as stainless steel or aluminum, and the like are mentioned. Among them, since high-precision formability is required for the unevenness of the adherend, it is particularly preferable to use a metal mold that can control the temperature during forming. The cooling method of the mold can adopt the usual cooling method. For example, cooling methods using water cooling or compressed air can be mentioned. For the mold, for example, as shown in Figure 2, a specific concave-convex shape is provided on the inner wall surface of at least one of the molds in the pair of open and close molds in advance, for example, in the bonding surface of the adherend that is provided with the adhesive layer. Concave-convex shape conforming to concave-convex part, convex part or concave-convex part, and the above-mentioned concave-convex shape can be transferred to the adhesive sheet by pressure forming, vacuum forming, pressure forming or roll forming of the adhesive sheet laminate using the mold The material is layered and shaped. As described above, it is preferable to start forming in a state where the surface temperature of the above-mentioned covering portion I is 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive material layer is sufficiently softened, and the covering part I can be deformed sufficiently, and if it is 180°C or lower, the generation of wrinkles caused by thermal shrinkage can be suppressed, or by Decomposition of the adhesive layer caused by heat and other disadvantages, so it is better. Therefore, it is preferable to start forming at a state where the surface temperature of the covering part I is 70 to 180° C., more preferably 75° C. or higher or 150° C. or lower, and more preferably 80° C. or higher or 120° C. below ℃. On the other hand, in this step, it is preferable to complete the molding in a state where the surface temperature of the above-mentioned covering portion I is less than 60°C. For example, in the case of press molding, it is preferable to open the mold in a state where the surface temperature is less than 60°C. Here, "completion of molding" means that the application of molding pressure to the adhesive sheet laminate is completed, and in the case of mold molding, it means that the mold is opened. If the surface temperature of the coating part I is less than 60° C., it is preferable to suppress deformation when the molded body is taken out after molding, or warping due to heat shrinkage of the coating part I. From this point of view, it is preferable to complete the forming when the surface temperature of the covering portion I is less than 60°C, especially preferably at 0°C or higher or 50°C or lower, and particularly preferably at Molding is completed in a state where the temperature becomes 10°C or higher or 40°C or lower. Although it is repeated, in this manufacturing method 2, the mold can be press-formed and cooled after the mold is opened, or the mold can be cooled in advance and cooled while press-forming. If the mold is cooled in advance in this way, and the cooling is performed simultaneously with press molding, the molding and cooling can be completed at the same time. Thereby, the shape-shaped adhesive sheet laminate can be conveyed to the next step immediately after completion of shaping and cooling, and thus the shape-shaped adhesive sheet laminate can be continuously manufactured. In the case of cooling while molding the mold, the surface temperature of the mold is preferably less than 60°C. If the surface temperature of the mold is less than 60°C, the shape of the adhesive sheet laminate can be fixed in a short time, and the obtained molded body has good precision, and can suppress warpage accompanying heat shrinkage during the cooling process after molding, Better from this point of view. Therefore, the surface temperature of the mold is preferably less than 60°C, more preferably 0°C or higher or 50°C or lower, and even more preferably 10°C or higher or 40°C or lower. Also, the difference in surface temperature of the coating portion I at the start of forming and the end of forming is preferably 10 to 100°C, and more preferably 20°C or higher or 90°C or lower. Since the surface temperature difference of the above-mentioned covering part I is 10 to 100°C, for example, when the above-mentioned concave-convex shape is transferred to the adhesive sheet laminate to form the shape, the shaped adhesive sheet can be formed immediately after finishing the forming and cooling. Since the laminate is transferred to the next step, a shape-shaped adhesive sheet laminate can be continuously produced. Furthermore, the conditions of press molding such as press pressure and press time are not particularly limited, and may be appropriately adjusted according to the size or shape to be formed, the material to be used, and the like. (Others) The shape-shaped adhesive sheet laminate obtained in the above forming and cooling steps can be wound up as it is, can also be heat-treated, and can also be cut into a specific size and shape. When cutting, the method of cutting using a Thomson blade, a rotary cutter, etc. is mentioned, for example. In this production method 2, it is preferable to continuously produce a shaped adhesive sheet laminate. For example, the adhesive sheet laminate may be conveyed to a heating unit such as a heater, and the conveyance may be stopped for a specified time in the heating unit for heating, or the heated adhesive sheet laminate may be conveyed to a molding machine after heating while conveying. In the forming unit, such as a forming mold, in the forming unit, for example, pressurized by a cooled mold, cooling is performed while forming, and then transferred to the next unit if necessary, and the shape-shaped adhesive sheet is continuously produced. laminated body. <Application> Here, an example of the utilization application of the shaped adhesive sheet laminate 1 will be described. In recent years, with the popularization of mobile phones, smart phones, tablet terminals, etc., there are many cases where the image display part is damaged due to user mistakes such as dropping them. In particular, when the image display device is a touch panel type, not only is it difficult to observe the display due to damage, but also the touch panel operation itself cannot be performed due to physical obstacles or water infiltration, or it becomes the cause of failure. . Therefore, there are cases where only the image display unit is replaced, that is, maintenance is performed. In the maintenance of the image display device, the adhesive sheet is also used when installing a new image display unit. Usually, maintenance is often performed manually by a repair operator, and the repair operator must be skilled. That is, if an unskilled person installs the image display part through the adhesive sheet, air may enter the inside or the adhesive may be squeezed out. On the other hand, if the shape-shaped adhesive sheet laminate 1 is used, since it is possible to preliminarily provide highly accurate step shapes, etc., for example, by preliminarily giving the adhesive material layer a pattern corresponding to the model of the image display device. The shape of the step difference can greatly simplify the maintenance work, and it can be implemented without the skill of the repair operator. As described above, the adhesive sheet laminate of the present invention can be usefully used for maintenance of image display devices. <Explanation of words> In this specification, when expressing "X~Y" (X, Y are arbitrary numbers), unless otherwise specified, it means "above X and below Y", and also Contains the meaning of "preferably greater than X" or "preferably less than Y". Also, when expressed as "more than X" (X is any number) or "below Y" (Y is any number), it also includes "preferably greater than X" or "preferably less than Y" meaning. In the present invention, the boundary between the sheet and the film is not definite, and it is not necessary to distinguish the two in the context of the present invention. Therefore, in the present invention, the term "film" also includes "sheet". The term "sheet" also includes "film".

On the other hand, as shown in Comparative Example 3-1, if the temperature of the covering portion 3-I at the start of forming is less than 70° C., sufficient unevenness cannot be formed on the adhesive layer even by thermoforming. Also, as shown in Comparative Example 3-2, when the surface temperature of the coating portion 3-I is 70° C. or higher when the molding is completed and the molded product is taken out from the mold, warping of the molded product occurs due to heat shrinkage of the sheet. Curved or bent and not good. From this, it can be seen that in order to form unevenness with higher precision, it is preferable to start forming at a state where the surface temperature of the covering portion 3-I is 70 to 180° C. After reaching 60°C, the molding is completed, and the molded product is taken out from the mold for molding. Therefore, it was confirmed that by using the above-mentioned adhesive sheet laminate, unevenness corresponding to the printing level difference of an image display device serving as an adherend can be precisely formed, and no gap between the adherend and the adherend can be produced. Furthermore, it is a shape-shaped adhesive sheet laminate for an image display device in which the adhesive material does not overflow and can be adhered to the adherend with a narrow edge design such as the printed part. In addition, in terms of peeling force, the heating and cooling conditions when measuring the peeling force F(D), that is, the conditions of heating at 100°C for 5 minutes and then allowing it to cool naturally to 30°C are those used when manufacturing a shape-shaped adhesive sheet laminate. Typical heating and cooling conditions. Since the absolute values of the difference between the peeling force F(C) and the peeling force F(D) in the above-mentioned examples were all 0.1 N/cm or less, it was confirmed that the peeling force hardly changed before and after heating.

Two types of amorphous sheets with three layers (surface layer/middle layer/surface layer) were obtained by melt extrusion with different melt extruders respectively. Next, a non-oriented sheet is obtained by coextruding the sheet onto a cooled casting drum and allowing it to cool and solidify. Then, after stretching 3.4 times in the machine direction (MD) at 82°C, it was further preheated in the tenter, and stretched 3.9 times in the direction perpendicular to the machine direction (width direction, TD) at 110°C.
