Also provided is such a pressure-sensitive adhesive tape as described below capable of protecting the uneven surface of a member having unevenness on its surface. The pressure-sensitive adhesive tape brings together sufficient pressure-sensitive adhesiveness for, and sufficient releasability from, the member. In addition, even upon deformation of the member protected with the pressure-sensitive adhesive tape by, for example, lamination or continuous winding, the uneven shape does not deform and a base material layer in the pressure-sensitive adhesive tape is not damaged, and further, the pressure-sensitive adhesive tape is adjusted so as to be capable of achieving compatibility between low haze property excellent in transparency and such large surface roughness that foreign matter such as a fish eye is hardly observed without fluctuations in mechanical properties of the entire pressure-sensitive adhesive tape. Also provided is such a pressure-sensitive adhesive tape as described below. When a prism sheet having multiple triangle pole-shaped prisms fixed on its surface is used as the above-mentioned member having unevenness on its surface, the pressure-sensitive adhesive tape functions as a surface protective film capable of effectively protecting a lens surface, and brings together sufficient pressure-sensitive adhesiveness for, and sufficient releasability from, the prism sheet. In addition, when the prism sheet protected with the pressure-sensitive adhesive tape is brought into a state such as a laminated state or a continuously wound state, the emergence of irregularity (indentation) in the external appearance of the prism sheet to which the pressure-sensitive adhesive tape is attached can be suppressed.

Description

201119855 VI. Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a laminated film and an adhesive tape. More specifically, it is a laminated film and an adhesive tape which are adjusted in haze value and surface roughness without changing the mechanical properties of the laminated film or the entire adhesive tape. Further, the present invention relates to an uneven surface capable of effectively protecting a member having irregularities on its surface. [Prior Art] In general, the film and the adhesive tape are adjusted to match the duty value and surface roughness of the purpose (for example, appearance adjustment). As a method of adjusting the haze value and the surface roughness, a τ-die extrusion contact roll forming method is known, that is, a molten resin extruded from a τ-shaped die is brought into contact with a metal roll having a concave-convex pattern, and the concave-convex pattern is transferred. A method of printing onto a surface of a resin (film surface) (for example, Japanese Laid-Open Patent Publication No. 2003-181962, JP-A No. 4,149,639). However, in the contact roll forming method of the stencil type, the problem of the processing failure of the molten resin being wound on the metal roll side due to insufficient cold portion of the secret grease at the time of high-speed molding is insufficient, or the uneven pattern of the metal roll is not sufficiently formed. The problem of transfer to the resin. In addition, in the stencil forming contact roll forming method, in order to improve the peeling of the molded article, the uneven surface is also applied to the rubber surface of the contact, and the unevenness affects the haze value of the molded article. Therefore, there arises a problem that it is difficult to obtain a molded article having a desired haze value (especially a medium-low haze value). As a method of "circumference value and surface roughness", in addition to the T-shaped mold contact 099123257 201119855, the τ-shaped air knife forming method or the blow molding air-cooling forming method can be cited, and the method of searching only by the refining of the resin to the cooling and solidification Since the flow is deformed to form a concave ridge on the surface of the molded article, it is difficult to form fine irregularities on the surface of the molded article. It has also been attempted to form a phase separation structure of an island by using a resin which is difficult to be compatible with two components or more, and which is a film-forming resin or a surface region of an adhesive tape. Degree value. However, when controlling the overall island structure of the film or the surface area of the adhesive tape to adjust the haze value and the surface roughness i, it is necessary to ensure the surface area or thickness of the film tape corresponding thereto. Therefore, the film or the adhesive tape Thinning is difficult. Further, it is necessary to appropriately adjust the material composition used in the formation of the surface area of the film formation or the adhesive tape in accordance with the haze value and the surface roughness. As a result, with the observation of the haze value and the surface roughness, the secret body or (4) the entire mechanical body f·sheng u greatly changes. Therefore, it is difficult to independently adjust the mechanical properties of the film as a whole or the adhesion of the film and the haze value and surface roughness of the film or the adhesive tape. In addition, in order to perform visual inspection in the state of protecting the object, the adhesive tape used as an engineering material such as a protective film needs to have a low haze. However, when the film having a low haze is such that a foreign matter such as a fish eye or a foreign matter mixed at the time of bonding is present in the film, the appearance defect can be visually observed. Therefore, it is conceivable to intentionally increase the surface roughness (i.e., roughening) of the film so that it cannot be visually observed. 099123257 6 201119855 t疋’-Generally speaking, the height of the haze and the beauty of the surface are proportional to the beauty of the surface. Therefore, when the surface roughness is increased, the haze becomes lower, resulting in a problem that the visual inspection cannot be performed. Further, in general, in order to protect the surface of various adherends, an adhesive tape in which an adhesive layer is laminated on the surface of the film-form substrate layer is widely used. = Aspects are expected to be in many to give a series, operability, optical function, And a member having irregularities formed on the surface. In the member of =, there is a problem that the dust adheres to the uneven portion or the problem of the convex portion = 艮 prevents the problem, and the adhesive tape as described above is used. ^Glue (four)' is a non-sticking force when a member having a concave-convex surface is formed on the protective surface. Therefore, it is necessary to use an adhesive tape which is soft in the adhesive layer and has high adhesion. However, when a soft adhesive is used in the adhesive layer, there is a problem that the top portion of the member which is formed into a concave portion on the surface of the adherend is broken and the top layer is broken, and the top portion of the concave portion is deformed. On the other hand, when the adhesive force between the member having the uneven surface formed on the surface and the adhesive tape is too strong, when the adhesive tape is peeled off from the member having the uneven surface formed thereon, there is a problem that the peeling cannot be smoothly performed. Therefore, the adhesive sword layer for protecting the adhesive tape of the member having the uneven surface on the surface needs to have the opposite properties of adhesiveness and peeling property, and at the same time, it is necessary to have the uneven top portion inaccessible to the adhesive tape substrate layer during protection. The degree of hardness. As an adhesive tape having a special adhesive layer, an adhesive tape using an adhesive layer having a thickness of ΙΟμίΏ or less as a main component of styrene 099123257 7 201119855 has been disclosed (for example, Japanese Patent Laid-Open No. 2007-332329 Bulletin). However, the adhesive tape disclosed in Japanese Laid-Open Patent Publication No. 2007-332329 is used for surface protection of a member having irregularities formed on the surface thereof, and the uneven top portion breaks through the adhesive layer to touch the base material layer, thereby deforming the uneven top portion. The problem. In addition, the adhesive tape disclosed in Japanese Laid-Open Patent Publication No. 2007-332329 has a problem that the adhesive force is insufficient to be naturally peeled off from the adherend due to the selection of the material, or the adhesive force is too strong to be able to The problem of smooth peeling off on the adherend. Further, in general, in order to protect the surface of various adherends, a surface protective film in which an adhesive layer is laminated on one surface of a film-form substrate layer is widely used. On the other hand, a sheet in which a plurality of triangular columnar crucibles are fixed on the surface of the sheet is used for various optical devices. In such a cymbal sheet, there is a problem that dust is attached to the lens surface (the enamel surface), or the lens portion (the enamel portion) is scratched. In order to prevent such a problem, a surface protective film as described above is used. The surface protective film for protecting the surface of the ruthenium is required to have a stable adhesive force which can be smoothly peeled off without peeling off during protection and peeling off without protection. Further, when the prism sheet is protected by such a surface protective film, it is necessary to prevent optical defects from being formed on the precisely formed enamel pattern. In the surface protective film for an optical member such as a crepe sheet, a rubber-based adhesive is generally used as the adhesive (for example, Japanese Laid-Open Patent Publication No. Hei 11-181370). 099123257 8 201119855 On the other hand, the ruthenium sheet to which the surface protective film is bonded is conveyed between steps in a state of a laminate or a state of a long roll. When the enamel sheet is laminated or the like, the lens portion (edge portion) of the cymbal sheet sometimes falls unevenly into the surface protective film due to the weight of the cymbal sheet itself. When unevenness (indentation) occurs in the appearance of the ruthenium sheet to which the surface of the protective film is bonded, it is difficult to perform the visual inspection of the enamel sheet in a state in which the surface protective film is bonded.

When the haze value of the laminated film of the present invention is 30% or less, the haze value of the base material layer may be any appropriate value. The base material layer contains a thermoplastic resin. As the thermoplastic resin, any suitable thermoplastic resin can be used as long as it can be formed by melt extrusion. Examples of the thermoplastic resin include polyolefin resins such as propylene-based polymers, polyethylene, and olefin-based thermoplastic elastomers, and modified products thereof; α-olefins and vinyl compounds (for example, vinyl acetate, Copolymer of (fluorenyl) acrylate; polyamine; polyester; polycarbonate; 099123257 13 201119855 polyamino phthalate; polyvinyl chloride; The propylene-based polymer may, for example, be a propylene homopolymer, a block polypropylene or a random polypropylene.

The base material layer may contain any appropriate additive as needed. The additive which may be contained in the base layer may, for example, be an ultraviolet absorber, a heat-resistant stabilizer, a filler or a lubricant. The kind, number, and amount of the additives contained in the above substrate layer can be appropriately set depending on the purpose. The ultraviolet absorber may, for example, be a benzotriazole compound, a diphenylketone compound or a benzoate compound. The content of the above ultraviolet absorbing agent may be any appropriate content as long as it does not bleed out when the laminated film is formed.

When the thickness of the rough presentation layer is larger than ΙΟμιη, the mechanical properties of the rough presentation layer affect the mechanical properties of the laminate film as a whole, and the workability of the laminate film is deteriorated. When the haze value of the laminated film of the present invention is not more than the above, the haze value of the above-mentioned thick chain expression layer may be any appropriate value. The above rough presentation layer comprises a material selected from the group consisting of polyethylene and ethylene. At least one of the vinyl acetate vinegar copolymer, the propylene conjugate, and the cerium (iv) thermoplastic elastomer = component (4). It is preferable to contain at least a difficult component (VIII) selected from the group consisting of a propylene polymer and an olefin thermoplastic elastomer. The propylene polymer 'specifically, for example, an acryl homopolymer, a ruthenium group, a random polypropylene group or the like can be mentioned. Further, as the _polymer, it is also possible to use a polypropylene obtained by using a metallocene catalyst as 099123257 15 201119855. As an olefin-based thermoplastic ketone, if it is an olefin-based phthalocyanine elastomer of the so-called TPO, it is possible to use an olefin-based thermoplastic elastomer that is suitable for use: a thermoplastic elastomer is representative of The part of the polystyrene paste is part of the soft component of the rubber component (hydrogenated (Phenylethyl)), or the female, called __Μ, occupation, negotiable soft bond segment. One of the two or more speeds, one of which is characterized by the inclusion of different enthalpy flow rates, and the rough presentation layer is formed by the material of the rough presentation layer. High-rate resin (low-viscosity resin) Resin which has a low maneuvering rate (high-viscosity resin) does not easily elongate, so it can be transferred to a resin having a sea portion which is formed by a resin having a high melt flow rate and having a low melt flow rate. Forming a rough representation layer of the island structure of the island portion. As a result, the surface roughness can be expressed in the thick chain expression layer by the irregularities formed by the island structure. The flow rate of the melt can be obtained by the basis of the melon 7210. Method to determine., 乂... The larva flow rate of the resin (low viscosity resin) of the worm speed surface is 1 good for minutes ~1GG (10) minutes, and even better 5g / l 〇 minutes, g 士 "! 5g / 1〇 minutes~5〇g/1〇 minutes. The above-mentioned melting flow rate 冋 of the resin (four) flow rate less than 5g / lG minutes, the above-mentioned melting 099123257 16 201119855 low flow rate of the resin and the above melt flow rate The difference in the melt flow rate of the high resin becomes small, and the surface roughness of the rough expression layer may become too small. When it is more than 100 g/10 minutes, the surface roughness of the rough expression layer may become excessive. The above melt flow rate is low. The smelting flow rate of the resin (high viscosity resin) is preferably 0. 1g/10 minutes ~ 4. 9g/10 minutes, even better. 2g/10 minutes ~ 4. 5g/10 minutes, especially good 0. 2g/10 minutes ~ 3g/10 minutes. The melt flow rate of the above-mentioned resin with low flow rate is less than that of 〇. At lg/l 〇 minutes, the surface roughness of the rough presentation layer may become excessive. When the amount is more than 7 g/10 minutes, the difference in melt flow rate between the resin having a high melt flow rate and the resin having a low melt flow rate becomes small, and the surface roughness of the rough expression layer may become too small. If the melt flow rate of the resin having a high melt flow rate (low viscosity resin) and the resin having a low flow flow rate (high viscosity resin) is within such a range, a sea portion formed by a resin having a high melt flow rate can be obtained. Roughness of the island structure of the island portion formed by the resin having a low melt flow rate 〇• By adjusting the melt flow rate of the above-mentioned resin having a high melt flow rate (low viscosity resin) and the resin having a low melt flow rate (high) The difference in the melt flow rate of the viscosity resin can control the surface roughness of the rough expression layer. That is, when the difference in the flow rate of the molten flow is large, the difference in the elongatability of the material of the rough expression layer is large, and the rough expression of 099123257 17 201119855 having a clear island structure can be obtained, so that the surface roughness is large. The coarse stitching layer. On the other hand, when the difference in the melt flow rate is small, the difference in the elongation property of the rough expression layer forming material is small, and it is difficult to obtain a rough expression layer having a clear island structure, and therefore, a rough surface having a small thickness is obtained. Chain presentation layer. The above rough expression layer is preferably one having a melting temperature Tm of two or more points in differential scanning calorimetry (DSC). Such a rough expression layer can be obtained by using two or more kinds of resins having different melting points. By using two or more kinds of resins having different melting points in the rough expression layer, the difference in surface roughness of the rough expression layer can be adjusted by the difference in melting point. More specifically, when the film is formed by heat-cooling and then solidified by cooling, the resin having a high melting point is first cured, and then the resin having a low melting point is solidified. Therefore, when the difference in melting point is large, it can be clearly defined in the above-mentioned rough expression layer. As a result of the island structure, a rough expression layer having a large surface roughness can be obtained. On the other hand, when the difference in melting point is small, it is difficult to obtain a thick chain expression layer having a clear island structure, and therefore, a thick chain expression layer having a small surface roughness is obtained. Further, the above melting temperature Tm can be measured by a method according to JIS K7121. In the present specification, "having a melting temperature Tm of two or more points" means that two or more melting endothermic peaks are generated in the DSC curve. When the above rough expression layer is formed using two kinds of resins having different melting points, the difference in melting point is preferably from 5 ° C to 65 ° C, more preferably from 10 ° C to 60 ° C, particularly preferably from 15 ° C to 50 ° C. When the difference in melting point is within such a range, a clear island structure can be obtained in the above-mentioned rough expression layer, and as a result, a rough expression layer having a large surface roughness can be obtained. The surface roughness of the above rough expression layer can be adjusted by the compatibility of two or more kinds of resins contained in the above-mentioned rough expression layer 099123257 18 201119855. When the compatibility is low, a clear island structure can be obtained in the above-mentioned rough expression layer, so that a rough expression layer having a large surface roughness can be obtained. On the other hand, when the compatibility is high, it is difficult to obtain a clear sea-island structure. Therefore, when the rough expression layer having a small surface roughness is obtained, when the above-described thick chain expression layer is formed, not only the method of using two or more kinds of resins as described above, but also There is a method of using a single resin. As such a single resin, for example, a block copolymer having a low viscosity portion (soft segment) and a high viscosity portion (hard segment) can be mentioned. Specifically, an olefin-based thermoplastic elastomer containing a block copolymer can be mentioned. According to the above, as the resin component (A) for forming the rough expression layer (the resin component (A) contained in the rough expression layer), for example, (1) a low viscosity resin and a high viscosity resin are preferable. Combination, (2) combination of high melting point resin and low melting point resin, (3) combination of low compatibility resin, (4) low viscosity part (soft segment) and high viscosity part (hard segment) Segment copolymer. Specifically, for example, a combination of a propylene-based polymer and an olefin-based thermoplastic elastomer, an olefin-based thermoplastic elastomer having a low-viscosity portion (soft segment) and a high-viscosity portion (hard segment). A commercially available product can be used as the above propylene-based polymer and olefin-based thermoplastic elastomer. Specific examples of the propylene-based polymer which is a commercially available product include a product name: WINTEC WX4" and "wintec WFX6" manufactured by POLYPRO Corporation, pp. 099123257 19 201119855. Specific examples of the olefin-based thermoplastic elastomer which is commercially available include a product name "Cataii〇y Q300F" manufactured by Sun Allomer Co., Ltd., and the like. The above rough expression layer may contain any appropriate additives as needed. As the additive which can be contained in the rough expression layer, for example, the additive described in the item A" can be used. A-3. Fine relief layer The thickness of the fine relief layer is preferably 1 to 1 Opm, more preferably Ιμπι~7μηι ‘, and more preferably Ιμηι~5μηι ‘Special 2μηι~5μιη. When the thickness of the fine unevenness-removing layer is less than Ιμηη, the fine unevenness cannot be sufficiently eliminated, and the haze value of the entire laminated film of the present invention becomes high. When the thickness of the fine concavo-convex-eliminating layer is larger than ΙΟμηη, even large concavities and convexities are buried, and the surface roughness of the laminated film of the present invention becomes smooth. When the haze value of the laminated film of the present invention is 30% or less, the haze value of the fine concavo-convex-eliminating layer may be any appropriate value. The fine unevenness eliminating layer contains a thermoplastic resin. As the thermoplastic resin, any appropriate thermoplastic resin can be used. For example, the thermoplastic resin described in the item Α-1 can be used. As the thermoplastic resin, polyethylene is preferred. In the laminated film of the present invention, the rough layer formed of the rough expression layer is composed of fine irregularities and large unevenness, but it is necessary to bury the fine unevenness by the above-mentioned fine unevenness eliminating layer 099123257 20 201119855 without burying the large unevenness . Therefore, the melt flow rate of the thermoplastic resin (B) contained in the fine relief-removing layer is preferably larger than the melt flow rate of any of the resin components (A) contained in the rough expression layer. The melt flow rate of the fine unevenness eliminating layer is preferably 6 g/i 〇 min to 100 g/10 min. L〇 minutes. A-4. Other Layers The laminated film of the present invention may have any other suitable layer (not shown) as needed. The thickness of the ruthenium layer is preferably from 2 μm to 12 μm, and more preferably from 5 μm to ΙΟμιη. As long as the haze value of the laminate film of the present invention is 30% or less, the haze value of the other layer may be any appropriate value. As the other layer, for example, a smooth layer can be mentioned. For example, when the laminated film has a rough presentation layer and a fine unevenness-removing layer on one side of the base material layer, the smooth layer is disposed on the side of the base material layer where the rough formation layer and the fine unevenness-removing layer are not disposed. As the material constituting the smoothing layer, any appropriate material can be employed.

S S 丨 i i ζ, - ε-660 201119855 It is apparent from Tables 1 and 2 that the laminated film and the adhesive tape obtained in the examples have a target haze value and surface roughness. Further, the laminated film obtained in the comparative example and the adhesive tape could not obtain the target haze value or surface roughness, and belonged to a general laminated film and an adhesive tape having a low haze value and a low surface roughness. Further, the laminated film and the adhesive tape which are obtained without the fine unevenness-eliminating layer obtained in Comparative Examples 11, 12, 15, and 16 can have high surface roughness, but the haze is increased and the penetrability is lowered, so that it is difficult to perform visual inspection. Defects. As shown in Table 3, the adhesive tape of the present invention is an adhesive tape capable of protecting the uneven surface of the member having irregularities on the surface, and has sufficient adhesion to the member and sufficient peelability, and the adhesive tape is protected by the adhesive tape. When the member is deformed as a laminate or a long roll, the uneven shape is not deformed, and the base material layer in the adhesive tape is not scratched, and is adjusted so as not to change the mechanical properties of the entire adhesive tape. High surface roughness with excellent penetrability, low haze, and difficulty in distinguishing foreign matter such as fish eyes. Further, in the adhesive tape of the present invention, when a ruthenium sheet having a plurality of triangular columnar cymbals fixed on its surface is used as a member having irregularities on the surface, the surface of the lens surface can be effectively protected as a surface protective film, and the ribs can be provided. When the lens is sufficiently adhesive and sufficiently peelable, and the ruthenium sheet protected by the adhesive tape is placed in a state of being laminated or rolled, it is possible to suppress unevenness (indentation) in the appearance of the prism sheet to which the adhesive tape is bonded. On the other hand, as shown in Table 4, in the case where the adhesive tape of the adhesive tape element of the present invention is not satisfied, it is not possible to have sufficient adhesion to the member having irregularities on the surface at the same time, and the adhesiveness and sufficient peelability may be used. When the member protected by the adhesive tape is deformed by lamination or long rolling, the uneven shape is deformed, or the base material layer in the adhesive tape is scratched, or the mechanical properties of the entire adhesive tape are changed, or may not be simultaneously Low haze property with excellent penetrability and south surface roughness that is difficult to discern the degree of foreign matter such as fish. Further, in the case where the adhesive tape of the adhesive tape element of the present invention is not satisfied, when a prism sheet having a plurality of triangular columnar crucibles is fixed as a member having irregularities on the surface, the lens surface cannot be effectively protected, or simultaneously When the prism sheet having sufficient adhesion to the cymbal sheet and the sufficient detachability or the prism sheet protected by the hexagram is used as a laminate or a long roll, unevenness occurs in the appearance of the cymbal to which the adhesive tape is attached (indentation). (Industrial Applicability) The laminated film and the adhesive tape of the present invention can be widely used for applications requiring design, such as protective use, appearance adjustment, and decorative use, for use in the manufacture of electronic components, structures, and automobiles. , label use, etc. In particular, the laminated film and the adhesive tape of the present invention have an appearance checkability by low haze property and a surface roughness which does not cause foreign matter to be misidentified, so that an efficient visual inspection can be performed. Further, the laminated film and the adhesive tape of the present invention can also be applied to an appearance regulating film of a film for design. For example, a member having excellent design properties, a film for decoration, a film for a label, a protection for an optical member, a film for designing an adjustment, and the like, which are required for the automotive industry or the residential building materials industry, have various methods of use. Further, the adhesive tape of the present invention is capable of protecting an adhesive tape having a concave-convex surface of a member having irregularities on the surface thereof, and has a pair of structures #μ and peeling property, and is used in a pair. When the full-adhesiveness of the member is fully modified, 2 = (4) The base layer of the layer is made into a slice or a long roll, etc., and the deformation occurs in the shape of the substrate, and the adhesive tape is not scratched. With the change of the mechanical properties of the whole:: ^The low-haze and the difficult-to-work with excellent penetrability are two: the degree of privacy and the surface roughness'. In addition, the bracts with the surface-fixed columnar column are used as When the above-mentioned surface has a member having irregularities, the (fourth) belt of the present invention can be used as a surface protection sheet, which has a sufficient adhesion to the sheet and sufficient peeling, and the sheet to be protected by the adhesive tape. Make a layer or a long roll. a can prevent unevenness of the appearance of the cymbal sheet to which the adhesive tape is attached, and is therefore suitable for use in, for example, the automotive industry or the building materials industry, and the design is provided by the formation of irregularities on the surface. The protection of the concave-convex member or the protection of the optical member having the uneven surface on the surface such as the cymbal sheet.
