Description

Laminated sheet and skin design sheet CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority based on Japanese Patent Application No. 2023-196541 filed on November 20, 2023, the entire disclosures of which are incorporated herein by reference.

[0002] The present invention relates to a laminated sheet and a skin-design sheet.

[0003] A skin design sheet that is applied to the skin is known (see, for example, Patent Document 1). The skin design sheet includes, for example, a release sheet, an adhesive layer, a base layer, and a protective sheet in this order in the thickness direction. The skin design sheet is applied to the user's skin by peeling the release sheet from the adhesive layer, applying the adhesive layer to the skin, and then peeling the protective sheet from the base layer.

[0004] Examples of skin design sheets include tattoo stickers and skin concealing sheets. Tattoo stickers are sheets with various designs printed on a substrate. Tattoo stickers are sold, for example, at variety stores, sporting and music event venues, amusement parks, etc., and are used to enhance the atmosphere. Skin concealing sheets are sheets on which a predetermined color has been pre-colored by screen printing or the like on the substrate. Skin concealing sheets are used, for example, to conceal discoloration such as scratches or blemishes on the skin. Users select a skin design sheet that matches their skin color.

[0005] Patent No. 6147874

[0006] However, the colors of skin-concealing sheets available on the market are limited, and the color difference between the skin-concealing sheet and the user's skin can be bothersome and dissatisfying. Therefore, studies have been conducted to provide skin-design sheets with a printed layer that matches the color of the user's skin by forming an image by on-demand printing from a photograph of the user. This can reduce the discomfort felt when the skin-design sheet is applied to the user's skin.

[0007] Such skin-pattern sheets are required to look natural when applied to the skin, but because skin is translucent, making it opaque through printing can result in an unnatural appearance due to the difference in appearance from the skin.Furthermore, wrinkles can occur when applied to the skin, resulting in an unnatural appearance.

[0008] An object of the present disclosure is to provide a laminated sheet that can be used as a skin-design sheet that suppresses the occurrence of wrinkles when applied to the skin and has a natural appearance.An object of the present disclosure is to provide a skin-design sheet that suppresses the occurrence of wrinkles when applied to the skin and has a natural appearance.

[0009] The laminate sheet of the present disclosure comprises at least a receiving layer, a hiding layer, and a base layer in this order, and the tensile test force of the laminate sheet at 5% tension over a width of 10 mm, obtained by a test method in accordance with JIS K7127:1999, is 0.10 N or more and 0.62 N or less.

[0010] According to the present disclosure, it is possible to provide a laminated sheet that can be used as a skin-design sheet that suppresses the occurrence of wrinkles when applied to the skin and has a natural appearance.Furthermore, according to the present disclosure, it is possible to provide a skin-design sheet that suppresses the occurrence of wrinkles when applied to the skin and has a natural appearance.

[0012] Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure can be implemented in many different forms, and should not be construed as being limited to the description of the following exemplary embodiments. For clarity of explanation, the drawings may show the width, thickness, shape, etc. of each layer more schematically than in the embodiments, but these are merely examples and do not limit the interpretation of the present disclosure. In this specification and each drawing, elements similar to those already described with reference to the previous drawings are designated by the same reference numerals, and detailed descriptions may be omitted as appropriate.

[0013] In the present disclosure, when multiple upper limit candidates and multiple lower limit candidates are listed for a certain parameter, the numerical range of the parameter may be constructed by combining any one upper limit candidate with any one lower limit candidate.

As an example, the following statement will be explained: "Parameter B is preferably A1 or greater, more preferably A2 or greater, and even more preferably A3 or greater. Parameter B is preferably A4 or less, more preferably A5 or less, and even more preferably A6 or less." In this example, the numerical range of parameter B may be A1 or greater and A4 or less, A1 or greater and A5 or less, A1 or greater and A6 or less, A2 or greater and A4 or less, A2 or greater and A5 or less, A2 or greater and A6 or less, A3 or greater and A4 or less, A3 or greater and A5 or less, or A3 or greater and A6 or less.

[0014] In this specification, each of the components (for example, resin materials and additives such as colorants) appearing in the following description may be used alone or in combination of two or more.

[0015] [Laminate Sheet] The laminate sheet of the present disclosure includes at least a receiving layer, a hiding layer, and a substrate layer in this order.

[0016] Specific examples of the laminate sheet of the present disclosure will be described below with reference to the drawings. The laminate sheet 1 shown in Fig. 1 includes a base layer 10, a concealing layer 20, and a receiving layer 30, arranged in this order in the thickness direction. In this example, an image of a desired color, such as a skin color, may be formed on the receiving layer 30 using a colorant such as a dye.

[0017] The laminate sheet may further include an adhesive layer (not shown) between the base material layer and the concealing layer. The laminate sheet may include a base material layer, an adhesive layer, a concealing layer, and a receiving layer in this order in the thickness direction.

[0018] The laminate sheet may further include a protective layer (not shown) on the base layer. The laminate sheet may include a base layer, a hiding layer, a receiving layer, and a protective layer in this order in the thickness direction.

[0019] The laminate sheet may further include an adhesive layer, a release sheet, and, if necessary, a protective sheet (not shown) on the surface of the substrate layer opposite the surface facing the receiving layer. The laminate sheet 1 shown in FIG. 2 includes a release sheet 50, an adhesive layer 40, a substrate layer 10, a concealing layer 20, and a receiving layer 30, in this order in the thickness direction. In this example, one or both of the substrate layers 10 may be colored with a colorant to a desired color, such as a skin color. A printed layer may be provided on one or both surfaces of the substrate layer 10. The laminate sheet may include, if necessary, a release sheet, an adhesive layer, a substrate layer, a concealing layer, a receiving layer on which an image is formed, a protective layer, and, if necessary, a protective sheet, in this order.

[0020] In one embodiment, the laminate sheet of the present disclosure is in the form of a long strip, and FIGS. 1 and 2 are cross-sectional views perpendicular to the longitudinal direction of the laminate sheet 1, for example.

[0021] <Substrate Layer> The laminate sheet of the present disclosure includes a substrate layer. Examples of the substrate layer include a resin film formed from a resin material. Examples of the resin material include polyurethane, polyester, polyamide, polyimide, polyolefin, vinyl resin, styrene resin, acrylic resin, and cellulose resin.

[0022] As the base layer, for example, a stretchable base material is preferably used. Examples of the stretchable base material include the above-mentioned resin films. Among the above-mentioned resin films, polyvinyl chloride (PVC) film, polyurethane film, and polyethylene film are preferred, and polyurethane film is more preferred.

[0023] The stretchable substrate preferably has an elongation percentage of 30% or more and 100% or less so that it can follow the expansion and contraction of the adherend when the laminate sheet is attached to the adherend. The elongation percentage of the stretchable substrate is the elongation percentage obtained by a test method in accordance with JIS K 7127:1999. The elongation percentage is expressed by the following formula (1): Elongation percentage (%) = 100 × (L - L0) / L0 (1)

[0024] In formula (1), L is the length at which the stretchable substrate breaks when it is pulled at a speed of 200 mm / min using a tensile tester. L0 in formula (1) is the length of the stretchable substrate before being pulled by the tensile tester. A Tensilon universal material testing machine can be used as the tensile tester.

[0025] The substrate layer may contain additives. Examples of additives include ultraviolet absorbers, light stabilizers, antioxidants, colorants, fillers, and release agents. The substrate layer may contain a colorant, if necessary. The substrate layer may contain a colorant to match the color tone of the laminated sheet to a desired color, such as skin color. Examples of colorants include pigments and dyes.

[0026] The thickness of the substrate layer is preferably 3 μm or more. A laminate sheet having a substrate layer with a thickness of 3 μm or more can, for example, suppress the occurrence of wrinkles when the sheet is applied. Furthermore, a laminate sheet having a substrate layer with a thickness of 5 μm or more can easily peel off and apply the release sheet from the laminate sheet without the substrate layer (sticker paper) becoming twisted, thereby improving workability. Furthermore, the thickness of the substrate layer is preferably 10 μm or less, more preferably 7 μm or less. A laminate sheet having such a substrate layer can, for example, suppress the user's discomfort after application of the sheet. Specifically, the thickness of the substrate layer is 3 μm or more and 10 μm or less.

[0027] A printing layer may be provided on the base layer. The printing layer may be a layer for adjusting the color tone of the laminated sheet to a desired color, such as skin color. The printing layer contains a colorant. Examples of the colorant include pigments and dyes.

[0028] <Concealing Layer> The laminate sheet of the present disclosure includes a concealing layer. Examples of the concealing layer include a white primer layer containing a white pigment and a resin material. Examples of white pigments include titanium oxide, zinc oxide, zinc sulfide, barium sulfate, and calcium carbonate. Among these, titanium oxide is preferred from the viewpoint of whiteness. The concealing layer can contain one or more white pigments.

[0029] The content of the white pigment in the concealing layer is preferably 40% by mass or more and 85% by mass or less, more preferably 50% by mass or more and 80% by mass or less. Here, by increasing the content of the white pigment in the concealing layer, it is possible to increase the concealing ratio of the concealing layer described below and the tensile test force of the laminate sheet at a width of 10 mm when stretched 5%. On the other hand, by decreasing the content of the white pigment in the concealing layer, it is possible to decrease the concealing ratio of the concealing layer described below and the tensile test force of the laminate sheet at a width of 10 mm when stretched 5%.

[0030] Examples of resin materials include (meth)acrylic resins, polyolefins, styrene resins, vinyl resins such as ethylene-vinyl acetate copolymers and vinyl chloride-vinyl acetate copolymers, polyesters, polyamides, imide resins, cellulose resins, polyol resins, polycarbonates, and ionomer resins. The hiding layer can contain one or more resin materials.

[0031] The hiding layer preferably contains either one or both of a (meth)acrylic resin and a polyol resin as the main resin material. This improves the dispersion stability of the white pigment in the hiding layer-forming coating liquid and suppresses the occurrence of coating defects, etc. The main resin material refers to a resin material that accounts for 70 parts by mass or more per 100 parts by mass of the total amount of resin materials contained in the hiding layer.

[0032] From the viewpoint of improving adhesion to the base layer when the concealing layer is transferred to the base layer, the concealing layer preferably contains a vinyl resin, more preferably a vinyl chloride-vinyl acetate copolymer. The vinyl resin content in the concealing layer is preferably 0.3% by mass to 10% by mass, more preferably 0.5% by mass to 5% by mass. This allows the adhesion of the concealing layer to the base layer to be further improved while maintaining the thermal transferability of the concealing layer.

[0033] From the viewpoint of improving adhesion to the base layer, the hiding layer preferably contains polyester. The content of polyester in the hiding layer is preferably 0.03% by mass or more and 1% by mass or less, more preferably 0.1% by mass or more and 1% by mass or less. This allows the hiding layer to maintain thermal transferability while further improving adhesion to the base layer.

[0034] The content of the resin material in the hiding layer is preferably 10% by mass or more and 70% by mass or less, more preferably 10% by mass or more and 50% by mass or less, which can prevent re-aggregation of the white pigment and achieve high hiding power.

[0035] The hiding layer may contain additives. Examples of additives include fillers, plasticizers, antistatic agents, UV absorbers, release agents, and dispersants. The hiding layer can contain one or more additives.

[0036] The thickness of the concealing layer is preferably 0.6 μm or more, more preferably 0.8 μm or more, and even more preferably 1.0 μm or more. The thickness of the concealing layer is preferably 6 μm or less, more preferably 5 μm or less, and even more preferably 4 μm or less. Here, increasing the thickness of the concealing layer can conceal the color of the base. On the other hand, decreasing the thickness of the concealing layer can reduce the concealing ratio of the concealing layer, which will be described later, and the tensile test force of the laminated sheet at a width of 10 mm when stretched at 5%. Specifically, the thickness of the concealing layer is 0.6 μm or more and 6 μm or less.

[0037] The hiding ratio (YB / YW) of the concealing layer, obtained by a test method conforming to JIS K5600-4-1, is a value calculated by measuring from the surface side of the receiving layer using a laminate sheet composed of an adhesive layer, a base layer, a concealing layer, and a receiving layer. Specific details will be described in the Examples below. The concealing ratio of the concealing layer is preferably 15% or more, more preferably 20% or more, and even more preferably 40% or more. Furthermore, the concealing ratio of the concealing layer is preferably 85% or less, more preferably 70% or less, and even more preferably 60% or less. Specifically, the concealing ratio of the concealing layer is 15% or more and 85% or less. If the concealing ratio of the concealing layer is 15% or more, a laminate sheet including the concealing layer can be used as a skin-design sheet and can effectively conceal blemishes and the like when attached to the skin. Furthermore, if the hiding ratio of the concealing layer is 70% or less, it becomes easy to adjust the tensile test force of the entire laminate sheet at a width of 10 mm when pulled by 5% within the required range. Furthermore, if the hiding ratio of the concealing layer is 60% or less, the laminate sheet having the concealing layer can be used as a skin design sheet and can have a more natural appearance when attached to the skin.

[0038] The concealing layer can be formed, for example, by applying a coating liquid obtained by dispersing or dissolving the components described above in a suitable solvent onto the substrate layer or any layer provided on the substrate of the transfer sheet using the known coating method described above, and drying the coating liquid.

[0039] (Adhesive Layer) The laminate sheet of the present disclosure may include an adhesive layer. In one embodiment, the laminate sheet may include an adhesive layer between the base layer and the concealing layer. In this case, when the concealing layer provided on the transfer sheet is transferred to the base layer, the adhesion between the base layer and the concealing layer can be improved.

[0040] The adhesive layer preferably contains a resin material. Examples of the resin material include (meth)acrylic resin, vinyl resin, polyolefin, polyester, polyurethane, epoxy resin, urea resin, melamine resin, and phenolic resin. The adhesive layer may contain one or more resin materials.

[0041] The content of the resin material in the adhesive layer is preferably 70% by mass or more and 100% by mass or less, and more preferably 80% by mass or more and 100% by mass or less.

[0042] The adhesive layer may be a layer obtained by curing a resin material with a curing agent, such as an isocyanate compound, an aliphatic amine, a cyclic aliphatic amine, an aromatic amine, or an acid anhydride.

[0043] The thickness of the adhesive layer is preferably 0.1 μm or more, more preferably 0.5 μm or more, and is preferably 10 μm or less, more preferably 2 μm or less. The thickness of the adhesive layer is, for example, 0.1 μm or more and 10 μm or less.

[0044] The adhesive layer can be formed, for example, by dispersing or dissolving the components described above in a suitable solvent to prepare a coating liquid, which is then applied onto the hiding layer by the known coating method described above and dried.

[0045] <Receptor Layer> The laminate sheet of the present disclosure includes a receptor layer. The receptor layer is a layer for receiving dyes and the like transferred from the thermal transfer sheet. For example, when forming an image using a printer, the image may be formed on a receptor layer preliminarily provided on a substrate layer, or the image may be formed on a receptor layer provided on a transfer sheet, and then the substrate layer may be transferred via a concealing layer. The image may be, for example, an image for adjusting the color tone of the laminate sheet to a desired color, such as skin color.

[0046] The material constituting the receiving layer may be, for example, a resin material. Examples of resin materials include polyolefins, vinyl resins, styrene resins, acrylic resins, polyesters, polyamides, polyimides, polyurethanes, polycarbonates, cellulose resins, and ionomer resins. Examples of polyolefins include polyethylene and polypropylene. Examples of vinyl resins include polyvinyl chloride, polyvinyl acetate, and vinyl chloride-vinyl acetate copolymers. Examples of polyesters include polyethylene terephthalate and polyethylene naphthalate. The resin material constituting the receiving layer is preferably a vinyl resin, and more preferably a vinyl chloride-vinyl acetate copolymer.

[0047] The content of the resin material in the receiving layer is preferably 70% by mass or more, and more preferably 80% by mass or more, based on the total mass of the receiving layer, which can provide the receiving layer with sufficient durability, for example.

[0048] The receiving layer may contain additives such as ultraviolet absorbers, light stabilizers, antioxidants, colorants, fillers, and release agents.

[0049] The content of the additive in the receiving layer is preferably 1% by mass or more, more preferably 2% by mass or more, and preferably 30% by mass or less, more preferably 20% by mass or less, based on the total mass of the receiving layer. The content of the additive in the receiving layer is, for example, 1% by mass or more and 30% by mass or less.

[0050] The thickness of the receiving layer is preferably 0.3 μm or more, more preferably 0.5 μm or more, and even more preferably 0.8 μm or more. The thickness of the receiving layer is preferably 5.0 μm or less, more preferably 3.0 μm or less, and even more preferably 2.0 μm or less. Here, if the thickness of the receiving layer is above the lower limit, sufficient print density cannot be obtained. On the other hand, if the thickness of the receiving layer is below the upper limit, the conformability when applied to the skin is insufficient, and a sense of unity with the skin cannot be obtained. The thickness of the receiving layer is, for example, 0.3 μm or more and 5.0 μm or less.

[0051] When a receiving layer is provided on a substrate layer in advance, the solvent contained in the coating liquid may melt and damage the substrate layer, or denature or deform the substrate layer during the process of applying and drying a coating liquid for the receiving layer on the hiding layer. In this case, it is preferable to transfer the receiving layer onto the substrate layer by thermal transfer. The receiving layer may be provided on the substrate layer in advance, or may be provided by thermal transfer onto the substrate layer during image formation.

Specific examples include resins obtained by adding a photopolymerization initiator to a radical polymerizable polymer or a radical polymerizable oligomer as needed, and polymerizing and crosslinking the resulting polymer or oligomer by irradiating it with an electron beam or ultraviolet light.

[0056] The content of the resin material in the protective layer is preferably 80% by mass or more, and more preferably 85% by mass or more, based on the total mass of the protective layer, which can provide, for example, sufficient durability to the protective layer.

[0057] The protective layer may contain additives. Examples of additives include ultraviolet absorbers, light stabilizers, antioxidants, colorants, fillers, and release agents. The protective layer may contain a colorant, if necessary. The protective layer may contain a colorant to match the color tone of the laminated sheet to a desired color, such as skin color. Examples of colorants include pigments and dyes.

[0058] The content of the additive in the protective layer is preferably 1% by mass or more, more preferably 2% by mass or more, and preferably 20% by mass or less, more preferably 15% by mass or less, based on the total mass of the protective layer.

The tensile test force is preferably 0.10 N or more and 0.41 N or less. If the tensile test force is within the above range, the occurrence of wrinkles when the laminate sheet is applied to the skin can be suppressed, and the laminate sheet can be used as a skin-design sheet with a natural appearance. Furthermore, if the tensile test force is 0.10 N or more and 0.41 N or less, the occurrence of wrinkles when applied to the skin can be more effectively suppressed when the laminate sheet is used as a skin-design sheet. Furthermore, the laminate sheet of the present disclosure can suppress the occurrence of print misalignment when printed using a thermal transfer printer, and can be used as a skin-design sheet with a natural appearance.

[0074] After extensive research, the inventors of the present application discovered that the tensile test force of the laminate sheet at 5% tension in a 10 mm width is affected by the thickness of the concealing layer constituting the laminate sheet and the content of the white pigment in the concealing layer. Specifically, increasing the thickness of the concealing layer and the content of the white pigment increases the tensile test force of the laminate sheet. Furthermore, if the tensile test force exceeds 0.62 N, wrinkles will occur when the laminate sheet is applied to the skin. On the other hand, decreasing the thickness of the concealing layer and the content of the white pigment decreases the tensile test force of the laminate sheet. This can suppress the occurrence of wrinkles when the laminate sheet is applied to the skin, but it also reduces the concealing ratio of the concealing layer.

[0075] The total thickness of the laminate sheet of the present disclosure, which is composed of the base layer, the concealing layer, and the receiving layer, is preferably 4.0 μm or more, more preferably 6.0 μm or more, and preferably 15.0 μm or less, more preferably 10.0 μm or less. The total thickness of the laminate sheet is, for example, 4.0 μm or more and 15.0 μm or less. When the total thickness of the laminate sheet is within the above range, the tensile test force at 5% tension at a width of 10 mm is likely to satisfy the above-mentioned requirements.

[0076] [Uses of Laminate Sheet] An example of the use of the laminate sheet of the present disclosure will be described below. In one embodiment, the laminate sheet can be used as a skin design sheet (skin sheet) to be attached to the skin by forming an image on the receiving layer. Examples of skin design sheets include skin concealing sheets and tattoo stickers. In addition, in one embodiment, the laminate sheet can also be used as a skin design sheet without an image by not forming an image on the receiving layer.

[0077] In one embodiment, a skin design sheet can be produced from the laminate sheet. For example, multiple skin design sheets may be produced from the laminate sheet. For example, a roll-shaped laminate sheet may be cut to produce a sheet-shaped laminate sheet in the form of a product.

[0078] The skin design sheet can be stuck to skin having spots, birthmarks, freckles, wrinkles, sagging skin, pores, scars, acne scars, burn scars, discoloration due to skin diseases, etc., so that the adhesive layer comes into contact with the skin, thereby concealing these and making them less noticeable.

[0079] In addition, by producing a skin design sheet on the laminated sheet by on-demand printing from a photographed image of the user, the color of the skin design sheet can be matched to the skin color of the user, thereby reducing the discomfort felt when the skin design sheet is applied to the user's skin.

[0080] [Method for manufacturing the skin design sheet] The skin design sheet of the present disclosure can be produced, for example, by a thermal transfer process. A long substrate film corresponding to the laminate sheet of the present disclosure is prepared. The substrate film may be provided with an adhesive layer and a release sheet. This substrate film and thermal transfer sheet are set in a thermal transfer printer.

[0081] The thermal transfer sheet comprises a substrate and a transferable receiving layer, a dye layer, and optionally a protective layer, which are provided in surface order on one side of the substrate. The receiving layer is a transparent layer that receives the dye transferred from the thermal transfer sheet. Examples of the dye layer include a yellow dye layer, a magenta dye layer, and a cyan dye layer. The dye layer contains a binder resin and a sublimable dye. Known materials can be used for the yellow dye layer, the magenta dye layer, and the cyan dye layer. Details of the receiving layer and the protective layer are as described above. If a receiving layer is already provided on the substrate film, it is not necessary for the thermal transfer sheet to have a receiving layer, or for the receiving layer to be transferred as described below.

[0082] The thermal transfer printer's thermal head and platen roll sandwich the substrate film and thermal transfer sheet, heating the thermal transfer sheet. The thermal head heats the receptor layer of the transfer mold, transferring the receptor layer onto the substrate film. Next, the thermal head sequentially heats the yellow dye layer, magenta dye layer, and cyan dye layer, for example, based on the data of the skin design sheet, transferring the dyes to the receptor layer transferred onto the substrate film to form an image. This makes it easy to match the color of the laminated sheet to the user's skin color. If necessary, the protective layer of the thermal transfer sheet is then heated and transferred onto the receptor layer on which the image has been formed.

[0083] If necessary, the surface of the base film may be subjected to a shaping process such as embossing to form a concave-convex shape. For example, an embossing plate or a shaping sheet can be used in the embossing process. The embossing plate and the shaping sheet can be used without any particular restrictions. The surface shape of the embossing plate and the shaping sheet and the surface shape shaped by them are almost the inverse of each other.

[0084] The long laminate sheet is cut parallel to the width direction of the laminate sheet using a cutter in a thermal transfer printer to obtain a single laminate sheet. If necessary, a protective sheet may be attached to the surface resin layer of the single laminate sheet.

[0085] Next, the laminated sheet is cut into the shape of the product form of the skin design sheet using a known cutting device. For example, when the laminated sheet is viewed from above, the laminated sheet is punched into a circular shape. The shape is not particularly limited.

[0086] In this way, a skin-design sheet having a desired shape can be produced. In the above method, the adhesive layer may be provided on the substrate film after the thermal transfer process. In this case, it is preferable to provide a release sheet after the adhesive layer is formed.

[0087] Although a method for manufacturing a skin design sheet by a thermal transfer process has been described, the method for manufacturing a skin design sheet of the present disclosure is not limited to the above method. For example, a skin design sheet may be manufactured by sequentially forming each layer of a laminated sheet.

[0088] In addition, in the method for producing a skin-design sheet of the present disclosure, an embodiment using a thermal printer has been described, but the present disclosure is not limited to this. As the printer, a thermal transfer printer, an inkjet printer, etc. can be used. Among these, a thermal transfer printer is preferred. As a thermal transfer printer, a dye-sublimation thermal transfer printer, which has excellent color reproducibility and gradation, is preferred.
