Each step will be described below.

(Release layer forming step)
The release layer forming step is a step of forming the release layer 3 on one surface of the peeled base material 2.

  The base material 2 to be peeled off is not particularly limited. For example, the base material 2 to be peeled is a resin sheet, paper, cloth, rubber sheet, foam sheet or the like. The resin sheet is a polyolefin-based resin sheet such as polyethylene (PE), polypropylene (PP), and ethylene-propylene copolymer; polyester-based such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN). Resin sheets; vinyl chloride resin sheets; vinyl acetate resin sheets; polyimide resin sheets; polyamide resin sheets; fluororesin sheets; cellophane and the like. Examples of the paper include Japanese paper, kraft paper, glassine paper, high-quality paper, synthetic paper, and top coat paper. Examples of the cloth include woven cloth and non-woven cloth made of various fibrous substances alone or mixed spinning. Examples of the rubber sheet include a natural rubber sheet and a butyl rubber sheet. Examples of the foam sheet include a foamed polyolefin sheet such as a foamed PE sheet, a foamed polyester sheet, a foamed polyurethane sheet, and a foamed polychloroprene rubber sheet. Among these, the base material is preferably made of polyethylene terephthalate (PET) for reasons such as physical properties (for example, dimensional stability, thickness accuracy, workability, tensile strength) and economic efficiency (cost). .

  The thickness of the base material 2 to be peeled off is not particularly limited. For example, the thickness of the base material 2 to be peeled is about 4 μm to 200 μm. When the thickness of the base material 2 to be peeled is within the above range, curling and wrinkles are less likely to occur in the base material, transferability is excellent, and cost is kept low.

  The release layer 3 is not particularly limited. For example, the release layer 3 is made of a release agent such as a silicone resin type, a fluorine resin type, a cellulose derivative resin type, a urea resin type, a polyolefin resin type, a melamine resin type.

  The method for forming the release layer 3 is not particularly limited. As an example, the release layer 3 can be formed by applying a release agent onto the substrate 2 to be peeled using a roll coater or the like.

  The thickness of the release layer 3 is not particularly limited. For example, the thickness of the release layer 3 is about 0.01 to 5 μm.

(Protective layer forming process)
The protective layer forming step is a step of forming the protective layer 4 containing the ultraviolet curable resin composition on the release layer 3.

  The protective layer 4 is not particularly limited. As an example, the protective layer 4 may include an ultraviolet curable resin composition. As an example, the ultraviolet curable resin composition is an ultraviolet radical curable resin including an ultraviolet curable monomer such as an epoxy acrylate resin, a urethane acrylate resin, or a thermosetting acrylic resin or a prepolymer thereof, and a photo radical polymerization initiator.

A cation-curable resin composition containing an agent, a cross-linking agent, and the like.

  The thickness of the protective layer 4 is not particularly limited. As an example, the thickness of the protective layer 4 is preferably 1.0 μm or more and 20 μm or less. When the thickness of the protective layer 4 is within the above range, the decorative film molded body 1 has excellent scratch resistance and abrasion resistance.

  The method for forming the protective layer 4 is not particularly limited. As an example, the protective layer 4 can be formed by applying a resin solution, which is appropriately dissolved in a solvent and forms the protective layer 4, onto the release layer 3 using a roll coater or the like. The applied resin solution is cured in a temporary curing step and a main curing step described later.

(Deposition layer forming step)
The vapor deposition layer forming step is a step of forming the vapor deposition layer 5 on the protective layer 4.

  The vapor deposition layer 5 is not particularly limited. As an example, the vapor deposition layer 5 is at least one type (also referred to as a metal or the like) selected from the group consisting of nonmetals, metals, metal oxides, and metal nitrides. The nonmetal, metal, etc. are not particularly limited. As an example, the nonmetal is amorphous carbon (DLC) and its composite, and the metal is at least one metal selected from the group consisting of silicon, titanium, tin, zinc, aluminum, indium and magnesium, and its oxidation. Thing, its nitride. Among these, the metal or the like is preferably aluminum, aluminum oxide, indium, tin, silicon oxide, silicon nitride, silicon oxynitride, aluminum zinc oxide (AZO), zinc tin oxide (ZTO), or the like. , Aluminum oxide, indium, and tin are more preferable. When the vapor deposition layer 5 is made of aluminum, aluminum oxide, indium, or tin, the obtained decorative film molded body 1 easily shows a metallic-like design feeling of satin plating.

  The method for forming the vapor deposition layer 5 is not particularly limited. For example, as a vapor deposition method, a conventionally known physical vapor deposition method such as a vacuum vapor deposition method, a sputtering method, an ion plating method, or a chemical vapor deposition method can be appropriately adopted. Among these, in the method for producing the decorative film molded body 1 of the present embodiment, the vapor deposition layer 5 is preferably provided by the vacuum vapor deposition method because of high productivity. As the vapor deposition conditions, conventionally known conditions can be appropriately adopted based on the material of the vapor deposition layer 5 and the desired thickness of the vapor deposition layer. In the case of depositing a metal, the metal material has few impurities and preferably has a purity of 99% by weight or more, and more preferably 99.5% by weight or more. In addition, the metal material is preferably processed into a granular shape, a rod shape, a tablet shape, a wire shape, or a crucible shape to be used. The heating method for evaporating the metal material is such that the metal material is placed in the crucible for resistance heating or high-frequency heating, electron beam heating is used, or the metal material is directly placed on a ceramic board such as boron nitride. A well-known method such as a method of performing resistance heating can be used. The crucible used for vacuum vapor deposition is preferably made of carbon, and may be an alumina, magnesia, titania or beryllia crucible.

  The thickness of the vapor deposition layer 5 is not particularly limited. As an example, the thickness of the vapor deposition layer 5 is preferably 7 nm or more, and more preferably 20 nm or more. Moreover, the thickness of the vapor deposition layer 5 is preferably 100 nm or less, and more preferably 80 nm or less. When the thickness of the vapor deposition layer 5 is within the above range, the vapor deposition layer 5 has appropriate flexibility, and irregularities 51 (see FIG. 2) are easily formed on the surface by the filler F described later.

(Adhesive layer forming step)
The adhesive layer forming step is a step of forming the adhesive layer 6 containing the filler F on the vapor deposition layer 5.

  The resin forming the adhesive layer 6 is not particularly limited. As an example, the adhesive layer 6 includes an acrylic resin type, a urethane resin type, a urethane modified polyester resin type, a polyester resin type, an epoxy resin type, an ethylene-vinyl acetate copolymer resin (EVA) type, a vinyl resin type (PVC, Vinyl acetate, vinyl chloride-vinyl acetate copolymer resin), styrene-ethylene-butylene copolymer resin system, polyvinyl alcohol resin system, polyacrylamide resin system, polyacrylamide resin system, isobutylene rubber, isoprene rubber, natural rubber, SBR, NBR , Resin such as silicone rubber. These resins may be appropriately dissolved in a solvent for use, or may be used without a solvent.

  The thickness of the adhesive layer 6 is not particularly limited. As an example, the thickness of the adhesive layer 6 is about 0.5 to 5 μm.

  The filler F is mixed in order to form the unevenness 51 on the surface of the vapor deposition layer 5 in the transfer substrate forming step described later.

  The filler F is not particularly limited. To give an example, the filler F is melamine resin particles, acrylic resin particles, acrylic-styrene copolymer particles, polycarbonate particles, polyethylene particles, polystyrene particles. Further, the filler F may be silica particles, talc, boron nitride, or the like.

  The shape of the filler F is not particularly limited. The shape of the filler F may be various fixed shapes, or may be an irregular shape such as a lens shape or a scale shape. FIG. 1 illustrates a lens-shaped filler F (lens-shaped filler F).

  The shape of the amorphous filler is preferably a shape other than a true sphere, more preferably a lens shape (elliptic sphere) or a scale shape. Since the amorphous filler has a shape other than a true sphere, the filler does not diffuse light in all directions and is unlikely to have a whitish appearance. As a result, the obtained decorative film molded body 1 easily expresses the metallic tone of satin plating.

  The size of the amorphous filler is not particularly limited. As an example, when the amorphous filler is a lenticular filler, the major axis L1 of the lenticular filler F is preferably 2.0 μm or more, and more preferably 6.0 μm or more. The major axis L1 of the lens-like filler F is preferably 20 μm or less, more preferably 10 μm or less. The thickness L2 of the lens-like filler F is preferably 1.0 μm or more, more preferably 2.0 μm or more. The thickness L2 of the lens-like filler F is preferably 5.0 μm or less, more preferably 3.0 μm or less. Furthermore, the aspect ratio (major axis / thickness) of the lenticular filler F is preferably 1.0 or more, more preferably 2.0 or more. Further, the aspect ratio of the lenticular filler F is preferably 10 or less, and more preferably 5.0 or less. When the dimension of the lens-like filler F is within the above range, the unevenness 51 having a desired dimension is likely to be formed on the surface of the vapor deposition layer 5 in the transfer substrate forming step described later. As a result, the obtained decorative film molded body 1 is likely to have both metallic luster and low image clarity.

  On the other hand, when the amorphous filler is a scaly filler, the major axis of the scaly filler is preferably 0.5 μm or more and 10 μm or less. Further, the thickness of the scale-like filler is preferably 0.05 μm or more and 0.5 μm or less. Furthermore, the aspect ratio (major axis / thickness) of the scale-like filler is preferably 10 or more and 150 or less. When the size of the scale-like filler is within the above range, unevenness of a desired size is likely to be formed on the surface of the vapor deposition layer in the transfer substrate forming step described later. As a result, the obtained decorative film molded product is particularly likely to have both metallic luster and low image clarity.

  When the adhesive layer 6 containing a filler is formed on the vapor deposition layer 5, the adhesive layer 6 is solidified with a part of the filler F exposed from the surface of the adhesive layer 6. FIG. 1 shows a state in which a part of the lenticular filler F is solidified while being exposed from the surface of the adhesive layer 6.

  The method for forming the adhesive layer 6 is not particularly limited. As an example, the adhesive layer 6 can be formed by using a roll coater or the like to apply a resin solution, which is appropriately dissolved in a solvent and forms the adhesive layer 6, onto the vapor deposition layer 5.

(Shielding process)
FIG. 4 is a schematic diagram for explaining the shielding step. The shielding step is a step of disposing the shielding plate 8 including the shielding portion 81 that shields ultraviolet rays and the non-shielding portion 82 that transmits ultraviolet rays on the other surface of the base material 2 to be peeled. The shielding step may be performed before the transfer base material forming step.

  The shielding plate 8 has a shielding portion 81 that shields ultraviolet rays and a non-shielding portion 82 that transmits ultraviolet rays. The material of the shield plate 8 is not particularly limited. For example, the shielding plate 8 is made of various resin materials, glass, or the like.

  The surface of the shield 81 is black and has a low transmittance for ultraviolet rays. Thereby, the ultraviolet rays applied to the shield plate 8 do not pass through the shield portion 81, but mainly pass through the non-shield portion 82. The ultraviolet rays transmitted through the non-shielding portion 82 reach the protective layer 4 and cure (temporarily cure) a part of the protective layer 4 along the shape of the non-shielding portion 82 in a temporary curing step described later.

  The shape of the non-shielding portion 82 is not particularly limited. For example, the shape of the non-shielding portion 82 can be appropriately determined according to the desired design. In FIG. 4, the case where the shape of the non-shielding portion 82 is a plurality of rhombuses is illustrated. The shield 81 does not have to completely shield the ultraviolet rays. At least the non-shielding portion 82 and the shielding portion 81 may have a predetermined transmittance difference with respect to ultraviolet rays.

(Temporary curing process)
The temporary curing step is a step of irradiating ultraviolet rays from the protective layer 4 toward the adhesive layer 6 so as to pass through the non-shielding portion 82 to temporarily cure the protective layer 4. The temporary curing step may be performed after the above-mentioned shielding step and before the below-described transfer base material forming step.

The method of irradiating with ultraviolet rays is not particularly limited. To give an example, the ultraviolet rays are irradiated from the protective layer 4 to the adhesive layer using an ultraviolet irradiation device (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.) so that the integrated light amount becomes 500 mJ / cm ^2. Irradiation can be performed in 6 directions. The irradiated ultraviolet rays do not pass through the shielding portion 81 of the shielding plate 8 but mainly through the non-shielding portion 82. The ultraviolet light transmitted through the non-shielding portion 82 reaches the protective layer 4 and cures (temporarily cures) a part of the protective layer 4 along the shape of the non-shielding portion 82 (plural diamonds in this embodiment).

(Transfer substrate forming process)
The transfer base material forming step is a step of forming (mounting) the transfer base material 7 on the adhesive layer 6.

  The transfer base material 7 (base material) is not particularly limited. The base material is a resin sheet, paper, cloth, rubber sheet, foam sheet, glass or the like. The resin sheet is a polyolefin resin sheet such as acrylonitrile / styrene (AS), acrylonitrile / butadiene / styrene (ABS), various acrylates, polycarbonate (PC), polyethylene (PE), polypropylene (PP), ethylene / propylene copolymer. Polyester resin sheet such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN); vinyl chloride resin sheet; vinyl acetate resin sheet; polyimide resin sheet; polyamide resin sheet; fluororesin sheet; cellophane Etc. are illustrated. Examples of the paper include Japanese paper, kraft paper, glassine paper, high-quality paper, synthetic paper, and top coat paper. Examples of the cloth include woven cloth and non-woven cloth made of various fibrous substances alone or mixed spinning. Examples of the rubber sheet include a natural rubber sheet and a butyl rubber sheet. Examples of the foam sheet include a foamed polyolefin sheet such as a foamed PE sheet, a foamed polyester sheet, a foamed polyurethane sheet, and a foamed polychloroprene rubber sheet. Among these, the base material is preferably made of acrylonitrile-styrene (AS) or acrylonitrile-butadiene-styrene (ABS) because of its excellent surface resistance and processability.

  The thickness of the base material is not particularly limited. As an example, the thickness of the base material is about 4 μm to 10 mm. When the thickness of the base material is within the above range, the base material has excellent workability and is easily transferred without impairing the appearance.

  As shown in FIG. 1, when the transfer substrate 7 is pressed against the adhesive layer 6 with the lens-like filler F exposed, the exposed lens-like filler F is pushed in the thickness direction of the adhesive layer 6. Be done. As a result, as shown in FIG. 2, the lenticular filler F is embedded in the thickness direction of the adhesive layer 6 and deforms the vapor deposition layer 5. As a result, unevenness 51 (a substantially bowl-shaped convex portion protruding toward the protective layer 4 side) is formed on the surface of the vapor deposition layer 5. As described above, the thickness of the lens-like filler F is preferably larger than the thickness of the adhesive layer 6. Thereby, the unevenness 51 is likely to be formed on the surface of the vapor deposition layer 5.

  The maximum diameter of the convex portion is preferably 2.0 μm or more and 20 μm or less. The height of the convex portion is preferably 0.5 μm or more and 5.0 μm or less. When the maximum diameter and height of the convex portions are within the above ranges, the degree of matting of the obtained decorative film molded body 1 is likely to be appropriately adjusted. As a result, in the decorative film molded body 1, the appropriate matteness and the gloss characteristics that contribute to the contrast are easily adjusted appropriately, and the satin-plated metal-like design feeling can be more accurately reproduced.

(Peeling process)
The peeling step is a step of peeling the base material 2 to be peeled off and the release layer 3. As shown in FIGS. 2 and 3, in the peeling step, the base material 2 to be peeled off and the release layer 3 are peeled off. As a result, the protective layer 4 is exposed.

(Main curing step)
The main curing step is a step of irradiating ultraviolet rays from the protective layer 4 toward the adhesive layer 6 to perform the main curing of the protective layer 4. The main curing step may be performed after the transfer base material forming step. The shielding plate 8 arranged in the shielding step may be removed at a proper time before the main curing step is performed. The main curing step is preferably performed after the peeling step. Thereby, in the main curing step, the protective layer exposed in the peeling step is irradiated with ultraviolet rays. Therefore, the obtained decorative film molded body is likely to be cured more uniformly.

The method of irradiating with ultraviolet rays is not particularly limited. As an example, the ultraviolet ray is irradiated from the protective layer 4 to the adhesive layer using an ultraviolet ray irradiator (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.) so that the integrated light amount becomes 1000 mJ / cm ^2. Irradiation can be performed in 6 directions. The irradiated ultraviolet rays reach the protective layer 4 and cure (main cure) the entire protective layer 4 including the portions (plural diamonds in the present embodiment) temporarily cured in the above-mentioned temporary curing step.

  As described above, according to the present embodiment, the protective layer 4 is cured along the shape of the non-shielding portion 82 by the ultraviolet rays that have passed through the non-shielding portion 82 in the temporary curing step. After that, in the transfer substrate forming step, the filler F is embedded in the adhesive layer 6, the vapor deposition layer 5 is deformed, and the unevenness 51 is formed. Further, in the main curing step, the entire protective layer 4 is cured. As a result, the first hardened portion of the protective layer 4 and the surrounding portion are hardened by separate steps (temporary hardening step and main hardening step), and the pattern with the faint contour is protected. Formed in layer 4. Further, when viewed from the direction from the protective layer 4 to the adhesive layer 6, the unevenness 51 formed on the vapor deposition layer 5 is formed at a position not overlapping with the unevenness 51 formed at a position overlapping the design in a top view. There are irregularities 51. All of these irregularities 51, when tilted by a predetermined angle, reflect light so as to raise the outline of the design (state in which the design is visible) and do not affect the outline of the design. It may change to the case where light is reflected (the pattern is difficult to see).

  FIG. 5 is a schematic view showing a state in which the decorative film molded body 1 is inclined so that the pattern is difficult to visually recognize. FIG. 6 is a schematic view showing a state in which the decorative film molded body 1 is inclined so that the design is visible. FIG. 7 is a photograph showing a state in which the decorative film molded body 1 is inclined so that the pattern is difficult to visually recognize. FIG. 8 is a photograph showing a state in which the decorative film molded body 1 is inclined so that the design can be visually recognized.

Each step will be described below. In the following description, the description of the same steps as those in the above-described first embodiment or second embodiment will be appropriately omitted.

(Release layer forming step, protective layer forming step, vapor deposition layer forming step and printing step)
The release layer forming step is a step of forming a release layer on one surface of the substrate to be peeled. The protective layer forming step is a step of forming a protective layer containing an ultraviolet curable resin composition on the release layer. The vapor deposition layer forming step is a step of forming a vapor deposition layer on the protective layer. The printing step is a step of forming a printing portion on the vapor deposition layer. The release layer forming step, the protective layer forming step, the vapor deposition layer forming step, and the printing step are all as described above in the second embodiment.

(Adhesive layer forming step)
The adhesive layer forming step is a step of forming an adhesive layer containing a filler on the vapor deposition layer on which the printed portion is formed. The adhesive layer forming step of this embodiment is the same as the adhesive layer forming step of the second embodiment described above except that a filler is included. The filler is the same as that described above in the first embodiment.

  According to the adhesive layer forming step, the adhesive layer is formed so as to cover the vapor deposition layer on which the printed portion is formed. When the adhesive layer containing the filler is formed on the vapor deposition layer, the adhesive layer is solidified with a part of the filler exposed from the surface of the adhesive layer.

The type and size of the transfer base material are the same as those described above in the first embodiment.

  When the transfer base material is pressed onto the adhesive layer, the printed portion provided on the vapor deposition layer is pressed in the thickness direction of the vapor deposition layer via the adhesive layer. As a result, the printing unit deforms the vapor deposition layer. As a result, irregularities (convex portions protruding toward the protective layer side) along the shape of the printed portion (that is, the shape of the pattern) are formed on the surface of the vapor deposition layer.

  Further, when the transfer base material is pressed onto the adhesive layer, the exposed filler is pressed in the thickness direction of the adhesive layer. As a result, the filler is embedded in the thickness direction of the adhesive layer and deforms the vapor deposition layer. As a result, unevenness (second unevenness) having a size different from the unevenness due to the above-described printing portion is formed on the surface of the vapor deposition layer. As described above, the thickness of the filler is preferably larger than the thickness of the adhesive layer. Thereby, irregularities are easily formed on the surface of the vapor deposition layer.

(Curing process)
The curing step is a step of irradiating ultraviolet rays from the protective layer toward the adhesive layer to cure the protective layer. The curing process is the same as the main curing process described above.

(Peeling process)
The peeling step is a step of peeling the base material to be peeled off and the release layer. According to the peeling step, the base material to be peeled off and the release layer are peeled off. As a result, the protective layer is exposed.

  As described above, according to the present embodiment, the vapor deposition layer is deformed along the shape of the design (printing portion) inside the decorative film molded body. Further, a pattern is provided as a printing portion inside the decorative film molded body. Further, the vapor deposition layer has fine irregularities formed by the filler. When viewed from the direction from the protective layer to the adhesive layer, the fine unevenness formed in the vapor deposition layer is formed in a position not overlapping with the fine unevenness formed at a position which overlaps with the design which is the printed part in a top view. There are fine irregularities. As a result, the degree of light reflection changes between the printing unit and its surroundings. Specifically, the decorative film molded body of the present embodiment, when tilted by a predetermined angle, reflects light so that the contour of the design is raised (state in which the design is visible) and the contour of the design Can be changed to a case where light is reflected so as not to affect (a state in which the pattern is difficult to see).

  As described above, in the decorative film molded body of the present embodiment, the printed portion forming the pattern is provided inside the decorative film molded body, and it is extremely difficult to duplicate. The surface of the protective layer is flat. Therefore, even if the surface of the protective layer is touched, the shape of the pattern cannot be confirmed. As a result, the decorative film molded body obtained in the present embodiment is, for example, a technology for imparting a function for preventing forgery to a medium such as a banknote or a securities, and an addition of anti-counterfeiting property to a product package. It is suitable as a technique for providing decoration. Moreover, the decorative film molded body of the present embodiment is suitable for the various uses described above in the first embodiment.

  In the above embodiment, the case where the surface of the protective layer is flat has been described. However, the present invention is not limited to this. In the decorative film molded product of the present invention, irregularities may be appropriately provided on the surface of the protective layer. As a result, the decorative film molded body has a unique dull metallic luster of satin-plated tone, and is given a matte design property, which can reduce reflection of human face, external light, illumination light, etc. .

<Decorative film molding>
The decorative film molded body of one embodiment of the present invention has a substrate, an adhesive layer, a vapor deposition layer, and a protective layer. The vapor deposition layer has irregularities formed on its surface. The adhesive layer contains a filler. The protective layer has a first region and a second region having a higher degree of polymerization than the first region. When the light from the light source of the multi-angle colorimeter is incident from an angle inclined by 45 ° from the normal direction of the protective layer, the specular reflection direction of the incident light is defined as 0 °, and the specular reflection direction indicates the light source. When the side is defined as a positive angle and the side opposite to the light source from the regular reflection direction is defined as a negative angle, the L * value (L1 * _-15 ) in the -15 ° direction in the first region is the second region. Is larger than the L * value in the −15 ° direction (L2 * ₋₁₅ ) in the first region, and the L * value in the first region (L1 * ₁₅ ) in the 15 ° direction is the L * value in the second region (L2 * ₋₁₅ ). * ₁₅ ) and the L * value (L1 * ₂₅ ) in the 25 ° direction in the first region is larger than the L * value (L2 * ₂₅ ) in the 25 ° direction in the second region. Each will be described below. In the following description, the description of the same configurations (for example, the base material, the adhesive layer, the vapor deposition layer, the protective layer, the filler, etc.) as those described above in relation to the method for producing a decorative film molded body will be appropriately omitted. To be done.

  In the decorative film of this embodiment, the protective layer has a first region and a second region. Each of the first region and the second region is a layer in which the resin solution forming the protective layer is cured. The second region of this embodiment has a higher degree of polymerization than the first region. That is, in the second area, the resin solution forming the second area is harder than the resin solution forming the first area.

  The method of increasing the degree of polymerization of the second region to that of the first region is not particularly limited. As an example, in the second region, as described with reference to FIG. 4, the base material 2 to be peeled is covered by the shielding plate 8 and ultraviolet rays are allowed to pass through the non-shielding portion 82 to temporarily cure the protective layer 4, Next, the shielding plate 8 is removed and the entire protective layer 4 is fully cured, whereby the degree of polymerization can be adjusted to be large. According to such a method, in the protective layer, the region where the temporary curing and the main curing are performed (the second region) is harder than the region where the main curing is performed (the first region). Further progress, the degree of polymerization is increasing.

  The decorative film molded body of the present embodiment is particularly preferably manufactured by the manufacturing method described above in relation to the method for manufacturing the decorative film molded body. That is, in the temporary curing step, a part of the protective layer is cured. Next, in the transfer base material forming step, the filler contained in the adhesive layer is pressed against the adhesive layer by the transfer base material to form irregularities on the surface of the vapor deposition layer. Then, in the main curing step, the entire protective layer is main cured. As a result, the first hardened portion of the protective layer and the surrounding portion are hardened in separate steps (preliminary hardening step and main hardening step), and a pattern with a faint contour is formed on the protective layer. Is formed. Further, when viewed from the direction from the protective layer to the adhesive layer, the unevenness formed on the vapor deposition layer includes unevenness formed at a position overlapping with the design in top view and unevenness formed at a position not overlapping with the design. . All of these irregularities, when tilted by a predetermined angle, reflect light so that the outline of the pattern rises (the state in which the pattern is visible) and light that does not affect the outline of the pattern. Can be changed to the case where the pattern is reflected (the pattern is difficult to see).

  More specifically, in the decorative film molded product of the present embodiment, L * in the highlight region in which the first region and the second region having different degrees of polymerization described above can be measured using a multi-angle colorimeter. The value is characterized by indicating a predetermined relationship. FIG. 12 is a schematic diagram for explaining how light from a light source of a multi-angle colorimeter is made incident on the decorative film molded body of the present embodiment. ND indicates the normal direction. In addition, in this embodiment, the multi-angle colorimeter uses "MA-T6" by x-rite, and can use a polychromatic white LED (D65 light source) as a light source. The measurement area may be 20 mm × 30 mm.

As shown in FIG. 12, when the light from the light source L of the multi-angle colorimeter is made incident on the first region and the second region of the protective layer 4 from the angle θ1 inclined by 45 °, The reflection direction RD is defined as 0 °. Further, the light source L side from the regular reflection direction RD is defined as a positive angle, and the side opposite to the light source from the regular reflection direction is defined as a negative angle. Then, L * in the -15 ° direction R _-15 , the 15 ° direction R ₁₅ , the 25 ° direction R ₂₅ , the 45 ° direction R ₄₅ , the 75 ° direction R ₇₅ , and the 110 ° direction R ₁₁₀ is measured.

In the decorative film molded product of the present embodiment, the L * value (L1 * _-15 ) in the -15 ° direction in the first region is greater than the L * value (L2 * _-15 ) in the -15 ° direction in the second region. Is also big. Similarly, the L * value (L1 * ₁₅ ) in the 15 ° direction in the first area is larger than the L * value (L2 * ₁₅ ) in the 15 ° direction in the second area. Further, the L * value (L1 * ₂₅ ) in the 25 ° direction in the first area is larger than the L * value (L2 * ₂₅ ) in the 25 ° direction in the second area. As described above, in the decorative film molded body of the present embodiment, in the highlight regions such as −15 °, 15 ° and 25 ° that are in the vicinity of the regular reflection direction RD, the L * value of the first region is the second. It is larger than the L * value of the two regions. Therefore, when the decorative film molded body is tilted by a predetermined angle, the pattern can be visually recognized due to the difference in the degree of reflection based on the difference in L * value between the first region and the second region, or It is possible to switch to a state that is difficult to see. Moreover, various base materials can be used for the decorative film molded body.

Further, in the decorative film molded body of the present embodiment, the difference in L * value between the first region and the second region is small in a region other than the highlight region (for example, a shade region). Specifically, the decorative film molded body of the present embodiment has an L * value (L1 * ₇₅ ) in the 75 ° direction in the first region and an L * value (L2 * ₇₅ ) in the 75 ° direction in the second region. And are about the same. Similarly, the L * value (L1 * ₁₁₀ ) in the 110 ° direction in the first area is about the same as the L * value (L2 * ₁₁₀ ) in the 110 ° direction in the second area.

  Thus, the decorative film molded body of the present embodiment, when visually recognized from the angle that is the highlight region, the difference in L * value becomes remarkable, and the pattern is easily visible, but when visually recognized from the angle that is the shade region, There is almost no difference in the L * value, making it difficult to see the pattern.

  Hereinafter, the present invention will be described more specifically with reference to Examples. The invention is in no way limited to these examples. In addition, "%" means "mass%" and "part" means "part by mass" unless otherwise specified.

The entire surface of the layer was temporarily cured and fully cured. Thereby, in Example 3, the second region was reproduced. On the other hand, in Example 4 described later, the temporary curing step was not performed. This reproduced the first region.

(Example 4)
A polyethylene terephthalate (PET) film (thickness: 25 μm) was used as a base material to be peeled, and an acrylic styrene resin (addition amount: 91 parts) and a curing agent (isocyanate, addition: 9 parts) were applied by a bar coater. This uncured resin layer was cured at 50 ° C. for 48 hours to produce a release layer (thickness: 1.0 μm) (release layer forming step). A polyfunctional acrylate resin solution (97 parts) and a photopolymerization curing agent (addition amount: 3 parts) were coated on the release layer with a bar coater to prepare a protective layer (thickness: 5.0 μm) (protection). Layer forming step). Acrylic resin (addition amount: 100 parts) was coated on the protective layer with a bar coater. This uncured resin layer was cured at 110 ° C. for 30 seconds to form a vapor deposition anchor layer (thickness: 1.0 μm). Aluminum was vacuum-deposited on the vapor deposition anchor layer using a resistance heating vapor deposition machine. An aluminum film (deposition layer) having a thickness of 35 nm was formed (deposition layer forming step). Acrylic resin (addition amount: 38 parts), urethane resin solution (addition amount: 57 parts), lens-like filler (acrylic, manufactured by Sekisui Plastics Co., Ltd., dimensions: major axis 7.2 μm, thickness 2.8 μm) on the vapor deposition layer. The addition amount: 5 parts) was applied by a bar coater to produce an adhesive layer (thickness: 1.0 μm) (adhesive layer forming step). After that, a black ABS plate (transfer base material) was pressed on the adhesive layer using an up-down transfer machine (MP-6 manufactured by Navitas Co., Ltd.), a pressing load of 1 kN, a marking temperature of 180 ° C., and a transfer time of 1.0 s. By pressing under the condition, the filler was embedded in the adhesive layer (transfer substrate forming step). As a result, the vapor deposition layer was deformed and irregularities were formed on the surface of the vapor deposition layer (details of the irregularities: an average major axis 4.1 μm, a convex shape with a height of 0.3 to 0.5 μm). Then, the base material to be peeled off and the release layer were peeled off (peeling step). Then, using an ultraviolet irradiation device (ECS-4011GX (using a high-pressure mercury lamp), manufactured by Eye Graphics Co., Ltd.), irradiation was performed from the protective layer toward the adhesive layer so that the integrated light amount was 1000 mJ / cm ^2. Curing process).

  With respect to the decorative film molded bodies obtained in Examples 1 to 4, L * values at various angles were measured by the following method. The results are shown in Table 1.

<Measurement of L * value>
When the light from the light source of the multi-angle colorimeter is incident from an angle inclined by 45 ° from the normal direction of the protective layer of each decorative film molded product, the specular reflection direction of the incident light is defined as 0 °. However, in the case where the light source side is defined as a positive angle from the regular reflection direction and the opposite side to the light source is defined as a negative angle from the regular reflection direction, the first region (Examples 2 and 4) and the second region The L * value in the region (Example 1 and Example 3) was measured. The angles at the time of measurement were −15 ° direction, 15 ° direction, 25 ° direction, 45 ° direction, 75 ° direction, and 110 ° direction. As the multi-angle colorimeter, "MA-T6" manufactured by x-rite was used, and a polychromatic white LED (D65 light source) was used as a light source. The measurement area was 20 mm × 30 mm.

  As shown in Table 1, comparing Example 1 in which the entire area is temporarily cured assuming the second region and Example 2 in which the first region is not temporarily cured, a highlight region (-15 The L * values at (° to 25 °) were larger in Example 2 than in Example 1. Further, in Example 1 and Example 2, almost no difference in L * value in the shade region was observed. As a result, the decorative film molded body including the second region of Example 1 and the first region of Example 2 has the first region and the second region when tilted by a predetermined angle. It was shown that the pattern can be switched to the visible state or the difficult-to-view state depending on the difference in the degree of reflection based on the difference in L * value. The same applies to Example 3 and Example 4.
