Description

  The present invention relates to a decorative sheet used for applying a pattern to an object to be decorated.

  In recent years, fashion that primarily decorates the skin, such as body painting and tattoo stickers, has become commonplace. Thus, as a technique for applying a pattern to a body to be decorated such as skin, for example, a decoration using a gold foil and a decoration method have been proposed (see Patent Document 1).

  This is because a base sheet with a decorative design die is attached to a body to be decorated, a liquid adhesive is applied, and a decorative body such as a gold foil is pressed onto the applied adhesive. Above, a base material sheet is peeled from a to-be-decorated body. As a result, the adhesive is applied to the object to be decorated at the part of the hole that has been punched into the base sheet, and the decorative body such as gold foil adheres only to the part to which the adhesive has been applied. Accordingly, a pattern can be applied to the object to be decorated.

  However, in the above prior art, it is necessary to perform an operation of applying an adhesive when decorating, which is troublesome.

  In addition, in this prior art, a pattern is formed by breaking a decorative body such as a gold foil by an external force at a boundary between a portion attached to the adhesive and a portion not attached. Therefore, there is a problem that a delicate pattern cannot be formed.

  On the other hand, as a tattoo sticker, a sticker for transferring a pattern printed by an ink jet printer onto the skin is also implemented. However, the pattern applied with such a seal is insufficient in color, and there has been a demand for a clearer pattern.

  In view of the above circumstances, an object of the present invention is to provide a decorative sheet capable of applying a delicate and clear pattern to a body to be decorated very easily.

  In order to solve the above-described problems, the decorative sheet according to the present invention includes: a support sheet having water permeability and flexibility, a water-soluble separation layer coated on the support sheet, and the separation layer. A decorative pattern layer in which a foil material is pressed into a predetermined shape through a transparent thermoplastic layer on the surface of the support sheet on the formed side, an adhesive layer laminated on the decorative pattern layer, and And a separator film that covers the support sheet from above the pressure-sensitive adhesive layer.

  The “support sheet” is a sheet having both water permeability and flexibility, and can be exemplified by paper.

  Examples of the material forming the “water-soluble separation layer” include starch, pullulan, dextrin, pectin, hypromellose, hydroxypropylcellulose, and methylcellulose.

  Examples of the “foil material” forming the “decorative pattern layer” include metal foil and pigment foil. Here, as metal foil, metal foil, such as gold, silver, platinum, aluminum, copper, titanium, and magnesium, can be used. Moreover, even if the metal foil is a foil material obtained by physical vapor deposition (PVD) or chemical vapor deposition (CVD) such as vacuum deposition, ion plating, and sputtering on a carrier film such as plastic, the metal is stretched. It may be a foil material.

  On the other hand, as the pigment foil, a foil material in which a synthetic inorganic pigment, a natural mineral pigment, or an organic pigment is coated on a carrier film can be used.

  The “thermoplastic layer” is a layer that softens by heating when the foil material is pressed and adheres the foil material to the object to be pressed. Even if this layer is coated on the foil material, the surface on which the separation layer of the support sheet on which the foil material is pressed is formed may be coated in the same shape as the decorative pattern layer. Examples of the material for forming the thermoplastic layer include acrylic resins, polyester resins, urethane resins, polyamide resins, vinyl chloride resins, and vinyl acetate resins.

  The “adhesive layer” is a layer for attaching the decorative pattern layer to the object to be decorated. As the adhesive, urethane adhesive, silicone rubber adhesive, acrylic adhesive, and natural rubber adhesive are used. It can be used.

  As the “separator film”, plastic films such as polyethylene terephthalate, polyester, polypropylene, and polycarbonate, and paper such as high-quality paper, kraft paper, and glassine paper can be used. If the “separator film” is transparent, the user can visually recognize the decorative pattern layer through the separator film, which is desirable.

  The “separator film” is preferably coated with a release agent on the surface in contact with the pressure-sensitive adhesive layer in order to protect the pressure-sensitive adhesive layer and facilitate peeling from the pressure-sensitive adhesive layer. As the release agent, a known release agent such as a silicone-based release agent can be used.

  With the above configuration, the decorative sheet of the present invention can be used as follows. First, the decorative sheet from which the separator film has been peeled is applied to the object to be decorated so that the pressure-sensitive adhesive layer is in contact with the object to be decorated. At this time, since the support sheet has flexibility, the entire decorative pattern layer can be brought into close contact with the object to be decorated even if the object to be decorated has irregularities.

  Next, a fingertip with moisture, or cotton, sponge, tissue paper or the like with moisture is applied to the support sheet. If it does so, a water | moisture content will permeate | transmit a water-permeable support sheet and will transfer to the layer for isolation | separation. Thereby, the separation layer that has joined the decorative pattern layer and the support sheet is dissolved, and the decorative pattern layer and the support sheet are separated. As a result, the decorative pattern layer that has been supported by the support sheet through the separating layer is transferred to the object to be decorated. Note that the thermoplastic layer remains on the decorative pattern layer transferred to the object to be decorated, but is transparent and does not impair the decorative properties exhibited by the decorative pattern layer.

  Therefore, according to the present invention configured as described above, a pattern formed of a foil material can be applied to the object to be decorated very simply by simply applying the decorative sheet to the object to be decorated and moistening it with moisture.

  In addition, since the decorative pattern layer is a layer formed by pressing a foil material, the decorative pattern layer can have a delicate pattern in which the shape of a mold used for foil pressing is directly reflected. Therefore, according to the present invention, a delicate pattern can be applied to the object to be decorated.

  Furthermore, the decorative pattern layer, which is a layer formed by stamping a foil material, has a larger thickness and a higher density of constituent materials than a layer formed by applying ink. Therefore, according to the present invention, a clear pattern with a clear outline can be applied to the object to be decorated. When the foil material is a metal foil, a gorgeous pattern with a strong metallic luster can be applied, and when the foil material is a pigment foil, a dark color pattern can be applied.

  The decorative sheet according to the present invention may have the above-described configuration, wherein “the decorative pattern layer includes a portion having a width of 0.05 mm to 0.5 mm”.

  As described above, the decorative pattern layer of the present invention is a layer formed by pressing a foil material, so that an extremely thin portion having a width of 0.05 mm to 0.5 mm is set depending on the setting of a mold used for foil pressing. Can be included. For example, it can be a decorative pattern layer having a curve that curves while changing the thickness (width) of the line or a complicated pattern in which a plurality of thin lines are intertwined.

  The decorative sheet according to the present invention has, in addition to the above-described structure, “permeability and flexibility from the support sheet, which is in contact with the support sheet on the surface opposite to the surface coated with the separation layer. A protective sheet having a small property ”.

  As the “protective sheet”, for example, cardboard and non-woven fabric can be used. In addition, the protective sheet may be formed by performing waterproofing treatment, such as coating wax or wax on a base material having water permeability.

  In the said structure, since the protection sheet | seat with less flexibility than a support sheet is provided, the possibility that the decorative pattern layer supported by the flexible support sheet | seat will deform | transform and damage by external force is reduced.

  In addition, since the protective sheet has a water permeability smaller than that of the support sheet, the possibility that moisture permeates the support sheet and dissolves the separation layer during storage of the decorative sheet is reduced.

  Further, the protective sheet can also serve as a sheet that receives the pressure of the pressing die when the foil material is pressed onto the support sheet. Thereby, the process which foil-presses a foil material on a support sheet can be performed stably. In addition, if the protective sheet is made of a material that has cushioning properties and can be recessed by pressurization, the pressure of the pressing die is absorbed by the protective sheet when the foil material is pressed, and the pattern exactly as the shape of the pressing die is formed. Since it is easy to be done, it is suitable. Alternatively, if the protective sheet is formed of a thick and hard material, the foil pressing operation can be performed quickly.

  In addition to the above configuration, the decorative sheet according to the present invention further comprises “a protective layer laminated in the same shape as the decorative pattern layer between the decorative pattern layer and the separating layer, The layer may be less water-soluble and transparent than the separating layer.

  Examples of the material for forming the “protective layer” include acrylic resins, epoxy resins, acrylamide resins, polyester resins, and polyurethane resins.

  Since the “protective layer” is less water-soluble than the separation layer, the protective layer is difficult to dissolve when the support sheet is wetted with water as described above to dissolve the separation layer. As a result, the protective layer can be left on the upper surface of the decorative pattern layer after the decorative pattern layer is transferred to the object to be decorated. Accordingly, the presence of the protective layer protects the decorative pattern layer formed of the foil material and enhances the wear resistance and waterproofness of the decorative pattern layer, so that the decoration by the decorative pattern layer can be prolonged.

  Since the “protective layer” is transparent, the decorative pattern layer can be protected without impairing the decorativeness exhibited by the decorative pattern layer.

  As described above, as an effect of the present invention, it is possible to provide a decorative sheet capable of applying a delicate and clear pattern to an object to be decorated very easily.

It is a disassembled perspective view of the decorative sheet of the first embodiment of the present invention. It is sectional drawing explaining the usage method of the sheet | seat for decoration of FIG. It is a figure which illustrates the decoration of the to-be-decorated body by the sheet | seat for decoration of FIG. It is a disassembled perspective view of the decorative sheet of the second embodiment of the present invention. It is sectional drawing in case the decorative sheet of FIG. 1 is provided with a cut line.

  Hereinafter, the decorative sheet 11 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 and 2 do not accurately illustrate the relationship between the thickness of each layer or sheet.

  The decorative sheet 11 includes a support sheet 2 having water permeability and flexibility, a water-soluble separation layer 3 coated on the support sheet 2, and the surface of the support sheet 2 on the side on which the separation layer 3 is formed. Further, a decorative pattern layer 5 in which a foil material is pressed into a predetermined shape via a transparent thermoplastic layer 5b, an adhesive layer 6 laminated on the decorative pattern layer 5, and a support from above the adhesive layer 6 A protective sheet 1 that is in contact with the support sheet 2 on the side opposite to the side coated with the separation layer 3 and the separator film 8 that covers the sheet 2 and that is less permeable and flexible than the support sheet 2 It is equipped with. In addition, a release agent layer is formed on the surface of the separator film 8 on the side in contact with the pressure-sensitive adhesive layer 6 by coating with a release agent.

  The decorative sheet having such a configuration can be manufactured as follows. First, the support sheet 2 is stacked on the protective sheet 1, and the separation layer 3 is formed on the support sheet 2. In the present embodiment, a thick paper having a thickness of 100 μm to 500 μm is used as the protective sheet 1. Further, glassine paper having a thickness of 20 μm to 30 μm is used as the support sheet 2, and the separation layer 3 is formed by coating starch on one surface thereof.

  On the other hand, the release agent layer 7 is formed on the separator film 8. In the present embodiment, a polyethylene terephthalate film is used as the separator film 8, and the release agent layer 7 is formed by coating a silicone release agent on one surface thereof.

  The decorative pattern layer 5 is formed by pressing a foil material onto the support sheet 2 through the separating layer 3. In the present embodiment, as a foil material, a case where a metal foil obtained by vacuum deposition of pure gold to a thickness of 500 to 1000 mm is used as a plastic carrier film is illustrated. The surface of this metal foil (the surface opposite to the carrier film) is coated with a transparent thermoplastic resin adhesive prior to foil pressing to form the thermoplastic layer 5b.

  A metal foil is stacked on the support sheet 2 stacked on the protective sheet 1 so that the thermoplastic layer 5b faces the separating layer 3, and the heated mold is pressed from the carrier film side of the metal foil, Pressurize. Thereby, the shape of the mold is reflected as it is, the metal foil is peeled off from the carrier film, and is adhered to the support sheet 2 via the softened thermoplastic layer 5b, whereby the decorative pattern layer 5 is formed. In FIG. 1, the illustration of the thermoplastic layer 5b is omitted.

  When a metal foil is pressed, if a mold having minute irregularities on the pressing surface is used, minute irregularities are formed on the surface of the decorative pattern layer 5. Due to the minute irregularities, light is reflected in various directions and the reflected lights interfere with each other, so that the pattern of the decorative pattern layer 5 is more decorative, for example, the color changes depending on the angle. Alternatively, even if a hologram foil on which minute irregularities are given in advance is used as the metal foil, the decorative pattern layer 5 rich in decorativeness is similarly formed.

  Next, the pressure-sensitive adhesive layer 6 is laminated on the decorative pattern layer 5. At this time, the shape of the pressure-sensitive adhesive layer 6 is preferably the same shape as the decorative pattern layer 5 or a similar shape slightly larger than the shape of the decorative pattern layer 5 (for example, about 0.5 mm to 1 mm). Such lamination can be performed by screen printing, gravure printing, or offset printing of an adhesive. In this embodiment, the adhesive is screen-printed using a stencil having the same shape as the pattern of the decorative pattern layer 5. As the adhesive, a urethane resin adhesive is used in this embodiment.

  And the decoration sheet 11 of the said structure can be obtained by coat | covering the support sheet 2 with the separator film 8 so that the adhesive layer 6 and the releasing agent layer 7 may face.

  Next, a method of using the decorative sheet 11 will be described with reference to FIG. When the decorative sheet 11 is stored, the support sheet 2 that supports the decorative pattern layer 5 and the pressure-sensitive adhesive layer 6 laminated on the decorative pattern layer 5 is protected from both sides by the protective sheet 1 and the separator film 8 ( (See FIG. 2 (a)).

  When decorating using the decorative sheet 11, first, the protective sheet 1 and the separator film 8 are peeled off (see FIG. 2B). At this time, since the release agent layer 7 is formed on the separator film 8, the separator film 8 is easily peeled off without damaging the adhesive layer 6 and the decorative pattern layer 5 on which the adhesive layer 6 is laminated. Can do.

  Next, the support sheet 2 is pressed against the portion of the body to be decorated 90 in a direction in which the pressure-sensitive adhesive layer 6 is in contact with the body to be decorated 90 (see FIG. 2C). In addition, before pressing the support sheet 2 against a to-be-decorated body, you may cut | disconnect between the decorative pattern layer 5 and other parts which are used for a decoration. Here, FIG. 2 shows the case where the surface of the object to be decorated 90 is flat. However, since the support sheet 2 is flexible, even if the surface of the object to be decorated 90 has unevenness, the unevenness is present. The support sheet 2 can be pressed along. Since the support sheet 2 is very thin, the support sheet 2 has sufficient flexibility even when the separation layer 3, the thermoplastic layer 5 b, the decorative pattern layer 5, and the pressure-sensitive adhesive layer 6 are laminated.

  In this state, lightly press the upper surface (the surface opposite to the surface on which the decorative pattern layer 5 is formed) of the support sheet 2 with a wet fingertip, or a wet cotton, sponge or tissue paper. So that it gets wet. If it does so, water will permeate | transmit the water-permeable support sheet 2, and water will transfer to the layer 3 for isolation | separation. Since the separation layer 3 is water-soluble, it is dissolved by the transferred water, and the decorative pattern layer 5 with the thermoplastic layer 5b and the support sheet 2 are separated (see FIG. 2D). As a result, the decorative pattern layer 5 and the thermoplastic layer 5 b remain in a state of adhering to the object to be decorated 90 via the adhesive layer 6, and the object to be decorated 90 can be decorated with the decorative pattern layer 5.

  For example, as shown in FIG. 3, decoration can be applied to the decollete, arms, legs, etc., with the body to be decorated 90 as human skin. In addition, the to-be-decorated body 90 can decorate the surface of objects, such as a stationery, a figurine, a mobile telephone, an electric product, and furniture, without being limited to a human skin.

  Next, the decorative sheet 12 of the second embodiment will be described with reference to FIG. The difference from the decorative sheet 11 of the first embodiment is that a protective layer 4 laminated in the same shape as the decorative pattern layer 5 is provided between the decorative pattern layer 5 and the separating layer 3. This protective layer 4 is less water-soluble than the separating layer 3 and is transparent. In addition, FIG. 4 does not show the thickness of each layer correctly like the above. Further, illustration of the thermoplastic layer 5b is omitted.

  Such a protective layer 4 is screen-printed with a protective agent using a stencil having the same shape as the pattern of the decorative pattern layer 5 on the surface of the support sheet 2 on the side of the separation layer 3 before pressing the metal foil. Can be formed. In the present embodiment, a transparent screen printing ink using an acrylic resin as a raw material is used as a protective agent.

  The decorative sheet 12 can also be used in the same manner as the decorative sheet 11 described above, but the protective layer 4 is less water-soluble than the separating layer 3, so that the supporting sheet 2 is wetted with water to separate the separating layer. When 3 is dissolved, it does not dissolve and remains on the upper surface of the thermoplastic layer 5b.

  As described above, according to the decorative sheet 11 of the first embodiment and the decorative sheet 12 of the second embodiment, the decorative sheets 11 and 12 are decorated after the protective sheet 1 and the separator film 8 are peeled off. It is possible to apply a luxurious and gorgeous pattern formed of metal foil to the object to be decorated 90 by an extremely simple operation by simply placing it on 90 and wetting it with water.

  And since the support sheet 2 is flexible, it can be along the surface which has an unevenness | corrugation, and even if it is the to-be-decorated body 90 which has an unevenness | corrugation on the surface, it can decorate without a problem.

  In addition, since the decorative pattern layer 5 is formed by stamping a metal foil, it can have a delicate pattern that directly reflects the shape of the foil stamping mold. Therefore, a delicate pattern having a very thin portion with a width of 0.05 mm to 0.5 mm can be applied.

  Furthermore, the decorative pattern layer 5 formed by stamping a metal foil has a thickness of 500 to 1000 mm, is thicker than the ink layer, and has a higher density of metal particles than an ink containing metal powder. Therefore, it is possible to apply a pattern having a clear outline and a strong metallic luster to the object to be decorated.

  Moreover, since the foil formed by vacuum deposition is used as a metal foil, the density of the metal is higher than that of a punched foil formed by stretching a metal. Thereby, the pattern of the decorative pattern layer 5 can be made into a more delicate and precise pattern. Moreover, since the metal density is high, the decorative pattern layer 5 has high mechanical strength and excellent wear resistance.

  Furthermore, glassine paper is used as the support sheet 2, but the glassine paper has a high density while having appropriate water permeability. When foil material is stamped on paper, a finer and more precise pattern can be formed when the paper density is higher. Therefore, in the above embodiment, the material of the support sheet 2 also contributes to making the pattern of the decorative pattern layer 5 delicate.

  Furthermore, in the decorative sheet 12 of the second embodiment, the wear resistance of the decorative pattern layer 5 is enhanced by the presence of the protective layer 4, and the decoration can be prolonged by suppressing damage to the decorative pattern layer 5. . Even when the object to be decorated 90 is human skin, the presence of the protective layer 4 protects the decorative pattern layer 5 from moisture such as sweat and cosmetics. Further, the presence of the protective layer 4 makes it difficult for the decorative pattern layer 5 to peel off even when it is rubbed with an operation of washing the skin by touching soapy water during bathing or washing. In addition, the period which can maintain a decoration can be adjusted and designed by selecting the kind of protective agent according to the kind and use of the to-be-decorated body 90. FIG.

  In both the decorative sheet 11 of the first embodiment and the decorative sheet 12 of the second embodiment, as shown in FIG. 5, the decorative pattern layer of the support sheet 2 coated with the separation layer 3 is used. A score line 9 can be made around 5. In FIG. 5, the case where the cut line 9 is provided in the decorative sheet 11 of the first embodiment is illustrated. Here, the cut line 9 can be provided by using a Thomson blade type or the like, but the depth of the cut line 9 is such that it reaches the middle of the protective sheet 1 beyond the separating layer 3 and the support sheet 2. It is desirable to do. Since the protective sheet 1 has a large thickness, it is easy to keep the cutting blade halfway during cutting. By providing such a cut line 9, the support sheet 2 can be easily separated between the decorative pattern layer 5 desired to be used for decoration and other portions.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the scope of the present invention as described below. And design changes are possible.

  For example, although the case where the pure gold foil was used as the metal foil was illustrated above, the present invention is not limited to this, and a foil made of other metals such as a silver foil and a platinum foil can be used.

  Furthermore, although the case where metal foil was used as the foil material was illustrated above, the present invention is not limited to this, and a pigment foil formed of pigments such as black, red, blue, and white can be used. The pigment foil has a thickness of 500 to 3000 mm, is thicker than the ink layer, and has a higher pigment density than the ink containing the pigment. Therefore, it is possible to apply a clear pattern with a very dark color and a clear outline to the object to be decorated.

  The protective layer 4 may be colored as long as it is transparent, and a protective agent can contain a colorant. For example, when the decorative pattern layer 5 is formed from a metal foil, the decorative layer 5 exhibits a color different from the color of the metal foil while having a metallic luster, because the protective layer 4 contains a colorant. It is possible to decorate the object to be decorated with more various patterns.

  Furthermore, the protective layer 4 can contain fine metal foil, metal powder, mica powder, fish scale powder, and the like. In this case, the decorative pattern layer 5 has a pearly luster, and the decorativeness can be further improved.
