  Embodiments of the present invention will be described in detail with reference to the drawings.

  First, how the transfer sheet 1 is formed by the method for producing a decorative sheet of the present invention will be described (see FIG. 1).

  The transfer sheet 1 is formed by first forming the hairline 7 after cooling the base sheet 2 (see FIGS. 1A and 1B), and then laminating the transfer layer 6 on the hairline 7 (FIG. 1). 1 (c)). As the transfer layer 6, a release layer 3, a decorative layer 4, and an adhesive layer 5 are usually formed.

  As the base sheet 2, polyester resin, polypropylene resin, vinyl chloride resin, polyethylene resin, polyethylene terephthalate resin, polycarbonate resin, nylon resin, vinylon resin, acetate resin, polyethylene resin, polyamide resin, polyacrylic resin, Plastic sheets such as polyvinyl chloride resins can be used. As the thickness of the base sheet 2, a sheet having a thickness of 10 to 500 μm may be used.

  In order to form the hairline stitches 7 after cooling the base sheet 2, it is preferable to use a hairline stitch forming device including a sheet supply roll 41, a sheet winding roll 42, a hairline stitch applying device 43, and a sheet cooling device 46. (See FIG. 2). In the hairline eye forming apparatus, a hairline eye giving device 43 is arranged in a base sheet passing line between the sheet supply roll 41 and the sheet take-up roll 42, and the base material sheet between the sheet supply roll 41 and the hairline eye giving device 43. The sheet cooling device 46 is arranged in the passage line.

  The formation of the hairline eyes 7 by the hairline eye forming apparatus will be described (see FIG. 2). First, the base sheet 2 supplied from the sheet supply roll 41 is subjected to, for example, cold air 49 from a sheet cooling device 46 provided with a cold air generating device 47 and a cold air outlet 48, so that the flexibility is lost. Solidify by cooling. In this way, the shavings from the base sheet 2 are easily separated from the base sheet 2 in the form of powder, and beautiful hairlines 7 can be formed on the base sheet 2. When the base sheet 2 is forcibly cooled to near the embrittlement point, for example, liquid nitrogen may be used as the refrigerant. Immediately after the cooling of the base sheet 2, for example, a roll around which the sandpaper belt 44 is wound by passing the base sheet 2 through a hairline eye applying device 43 including a roll around which a rotating sandpaper belt 44 is wound and a rubber roll 45. The hairline 7 is formed on the surface of the base sheet 2 by rotating it against the surface. After forming the hairline 7, the base sheet 2 is allowed to absorb external heat to restore flexibility, and finally the base sheet 2 is wound up by the winding roll 41.

  Here, when the base sheet 2 is cooled, it may be cooled from the hairline eye forming side or from the side opposite to the hairline eye forming side, but particularly when the thickness of the base sheet 2 is large, the hairline eye forming side. Is cooled, the cooling of the base sheet 2 can be minimized. In this way, it is possible to shorten the time until the flexibility of the base sheet 2 is restored, which is suitable for preventing the productivity of the transfer sheet from being lowered. In addition, applying warm air to the base sheet 2 immediately after the formation of the hairline 7 is effective in shortening the time until the base sheet 2 is restored to flexibility (not shown).

  Further, instead of the sandpaper belt 44, the hairline eye applying device 43 may be a metal brush, a hairline abrasive in which abrasive grains are attached to a nonwoven fabric, steel wool, or the like. Further, the rubber roll 45 may be replaced with, for example, a metal member or removed as long as there is no problem in forming the hairline.

  As the transfer layer 6, the release layer 3 may be formed as necessary in order to ensure the release from the base sheet 2. The release layer 3 is a layer that peels from the base sheet 2 and becomes the outermost surface of the transfer object. The release layer 3 can be made of acrylic resin, polyester resin, polyvinyl chloride resin, cellulose resin, rubber resin, polyurethane resin, polyvinyl acetate resin, or vinyl chloride-vinyl acetate copolymer. Copolymers such as system resins and ethylene-vinyl acetate copolymer resins may be used. When the release layer 3 requires hardness, a photo-curing resin such as an ultraviolet curable resin, a radiation curable resin such as an electron beam curable resin, or a thermosetting resin may be selected and used. Examples of the method for forming the release layer 3 include a coating method such as a gravure coating method, a roll coating method, and a comma coating method, and a printing method such as a gravure printing method and a screen printing method.

  As a material of the decorative layer 4, a resin such as a polyvinyl resin, a polyamide resin, a polyester resin, an acrylic resin, a polyurethane resin, a polyvinyl acetal resin, a polyester urethane resin, a cellulose ester resin, or an alkyd resin is used. A colored ink containing a suitable color pigment or dye as a colorant may be used as a binder. As a method for forming the decorative layer 4, a normal printing method such as a gravure printing method, a screen printing method, or an offset printing method may be used. As thickness of the decoration layer 4, 1-30 micrometers is preferable. The decorative layer 4 is not limited to colored ink, and may form a metal vapor deposition layer or the like to express a design with metallic luster. Aluminum, chromium, copper, tin, or the like is used as the material for the metal deposition layer. The metal vapor deposition layer may be formed by using a vacuum vapor deposition method, a sputtering method, an ion plating method, or the like.

  Moreover, you may form the contact bonding layer 5 as needed. The adhesive layer 5 is a layer for adhering the transfer sheet to the resin molded product 8 by a transfer method or a simultaneous molding transfer method described later. When the material of the resin molded product 8 is a polyacrylic resin, a polyacrylic resin may be used as the material of the adhesive layer 5. Further, when the material of the resin molded product 8 is polyphenylene oxide / polystyrene resin, polycarbonate resin, styrene copolymer resin, or polystyrene blend resin, polyacrylic resin or polystyrene resin having affinity with these resins Polyamide resin or the like may be used as the material for the adhesive layer 5. As a method for forming the adhesive layer 5, a gravure coating method, a roll coating method, a comma coating method or the like, a gravure printing, a screen printing method, or the like may be used. The dry film thickness of the adhesive layer 5 is generally 1 to 5 μm.

  Next, a method for manufacturing a transfer molded article 11 (see FIG. 5) using the transfer sheet 1 will be described.

  Examples of the thermoplastic resin used for the resin molded product 8 for forming the transfer molded product 11 include polyolefin resins such as polyethylene and polypropylene, polystyrene resins, polyvinyl chloride resins, poly (meth) acrylate resins, Any known thermoplastic resins such as acrylic resins, polyacetal resins, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyamide resins, polycarbonate resins, polyphenylene sulfide resins and polyimide resins can be used. These resins can be used alone or in admixture of two or more.

  The transfer process of transferring the transfer layer 6 from the transfer sheet 1 onto the resin molded product 8 by the transfer method is performed as follows (see FIG. 3). First, the transfer layer 6 side of the transfer sheet 1 is brought into close contact with the surface of the resin molded product 8. Next, using a transfer machine such as a roll transfer machine or an up-down transfer machine provided with a heat-resistant rubber-like elastic body 21 such as silicon rubber, the heat-resistant rubber is set at a temperature of about 80 to 260 ° C. and a pressure of about 500 to 2000 Pa. Heat and pressure are applied from the substrate sheet 2 side of the transfer sheet 1 through the elastic body 21. By doing so, the transfer layer 6 adheres to the surface of the resin molded product 8. Finally, when the base sheet 2 is peeled off after cooling, the transfer layer 6 is transferred to the surface of the resin molded product 1 and the transfer process is completed.

  The transfer step of transferring the transfer layer 6 from the transfer sheet 1 onto the resin molded product 8 by the simultaneous molding transfer method is performed as follows (see FIG. 4). First, the transfer sheet 1 is fed into a molding die 31 composed of a movable die and a fixed die so that the surface on which the transfer layer 6 is not formed faces the die cavity. At that time, the sheet-like transfer sheets 1 may be fed one by one, or necessary portions of the long transfer sheet 1 may be intermittently fed. When the long transfer sheet 1 is used, the transfer sheet 1 is placed in the mold so that the registration of the transfer sheet 1 and the molding die 31 coincide with each other using a feeding device having a positioning mechanism. Good. Further, when the transfer sheet 1 is intermittently fed, the transfer sheet 1 may be fixed by a movable mold and a fixed mold after the position of the transfer sheet 1 is detected by a sensor. After the molding die 31 is closed, the molding resin 32 is injected and filled from the gate into the die and then cooled and solidified to form the resin molded product 8 and at the same time, the transfer sheet 1 is adhered to the surface (see FIG. 4 (a)). After the resin molded product 8 is cooled, the molding die 31 is opened and the resin molded product 8 is taken out. Finally, when the base sheet 2 is peeled off, a transfer molded product 11 in which the transfer layer 6 is transferred onto the surface of the resin molded product 8 is formed (see FIG. 4B).

  This transfer molded article 11 is excellent in the design of the hairline 7 without any appearance defect due to traces of thread-like shavings generated when the hairline 7 is processed.

  Moreover, the insert sheet 51 can also be used as a decorating sheet (refer Fig.6 (a)). Since the base sheet 2 is not peeled after the insert sheet 51 is bonded to the resin molded product 8, the layer configuration is different from that of the transfer sheet 1 in that the peeling layer 3 is not provided. The insert sheet 51 is placed in the mold so that the surface of the base sheet 2 on which the decorative layer 4 is not formed faces the mold cavity, and the molding resin is poured into the mold, and then cooled and solidified to be integrated. By doing so, the insert molded product 52 can be formed (see FIG. 6B).

  Moreover, the insert sheet 51 by which the decoration layer 4 was formed in the surface opposite to the hairline eyes 7 formation surface on the base sheet 2 in which the hairline eyes 7 were formed can also be used as another aspect of the insert sheet 51 ( FIG. 7 (a)). When such an insert sheet 51 is used, a hairline processed surface can be formed on the surface of the insert molded product 52 (see FIG. 7B).

  In addition, the insert sheet 53 can also be formed by transferring the transfer layer 6 from the transfer sheet 1 to the back sheet 61 (see FIGS. 8A and 8B). Further, a new insert sheet 54 may be formed by further laminating a surface sheet 62 on the transfer layer 6 of the insert sheet 53 (see FIG. 8C).

  The back sheet 61 is a sheet made of a thermoplastic resin that can be bonded to the molding resin 32. Since the back sheet 61 is a sheet for integrally bonding the injected molded product and the decorative sheet, it is preferable to select the same type of resin as the molding resin 32. This is because the compatibility is enhanced and the adhesion is made stronger. The back sheet 61 is also a sheet that is relatively strong and makes it difficult for the influence of the heat pressure of the molding resin 32 to reach the decorative layer 4. In addition, the back sheet 61 can retain its three-dimensional shape even after the insert sheets 53 and 54 that have been formed into a desired three-dimensional shape by a known vacuum forming method, pressure forming method, or the like are cooled to room temperature. It is also a sheet for enabling the decorative layer 4 not to be destroyed even when the expansion / contraction rate is large. Examples of the material of the back sheet 61 include acrylic resin, polycarbonate resin (PC resin), acrylonitrile-butadiene-styrene copolymer resin (ABS resin), polystyrene resin, polyurethane resin, nylon resin, ethylene vinyl alcohol resin, and the like. . All have a thickness in the range of 50 to 200 μm.

  The top sheet 62 is a sheet having a function of protecting the decorative layer 4 after the insert sheet 54 is integrally bonded to the surface of the resin molded product 8. When it is necessary to transmit the handle of the decorative layer 4, it is necessary to have light transmittance. Examples of the material of the surface sheet 62 include acrylic resin, polycarbonate resin (PC resin), acrylonitrile-butadiene-styrene copolymer resin (ABS resin), polystyrene resin, polyurethane resin, nylon resin, ethylene vinyl alcohol resin, and the like. .

  In order to manufacture an insert molded product, which is a decorative molded product, using the insert sheets 53 and 54, the insert sheets 53 and 54 are hot-pressure molded into a desired three-dimensional shape by vacuum molding or pressure molding, and then injection molded. The mold is injected into the mold and the molding resin is injected, and the back sheet 61 side of the insert sheets 53 and 54 is integrally bonded and decorated on the surface of the molded product. The desired three-dimensional shape means a three-dimensional shape intended by the practitioner. Vacuum forming is the most widely used method of thermoforming. Heating and softening is performed while the sheet is clamped on the mold, the gap between the mold and the sheet is evacuated, and the sheet is brought into close contact with the mold. In addition, it refers to a method of releasing a vacuum after cooling and taking out a three-dimensional molded product (sheet). In addition, when setting a vacuum degree high with respect to the sheet | seat which can be extended | stretched at normal temperature, a sheet | seat can also be closely_contact | adhered to a type | mold at normal temperature. The compressed air molding is a method in which a heated and softened sheet is clamped, the sheet is stretched by the force of compressed air, conformed to the mold, and after cooling, the compressed air is released to take out a three-dimensional molded product (sheet). Say.

  The base sheet 2 is formed using a hairline eye forming apparatus including a polyethylene terephthalate film having a thickness of 75 μm as the base sheet 2, and a sheet supply roll 41, a sheet take-up roll 42, a hairline eye giving device 43, and a sheet cooling device 46. A hairline 7 having an unevenness difference of 3 μm was formed on the surface (see FIGS. 1A, 1B, and 2). The shavings of the base sheet 2 became powdery and was easily detached from the base sheet 2, and beautiful hairlines 7 were formed on the base sheet 2. By forming the release layer 3, the decorative layer 4, and the adhesive layer 5 sequentially on the hairline 7 of the base sheet 2 by the gravure printing method, the release layer 3, the decorative layer 4, and the adhesive layer 5 are formed as the transfer layer 6. A laminated transfer sheet 1 was obtained. Here, the release layer 3 was made of polyurethane ink, the decorative layer 4 was made of acrylic ink, and the adhesive layer 5 was made of vinyl chloride-vinyl acetate copolymer ink (see FIG. 1C).

  The transfer sheet 1 formed in this way is placed in the mold so that the surface of the base sheet 2 on which the transfer layer 6 is not formed faces the mold cavity, and is clamped and then molded in the mold. The resin 32 was poured and cooled and solidified to obtain a resin molded product 8. The base sheet 2 was peeled from the obtained resin molded product 8 to obtain a transfer molded product 11 having a transfer layer 6 on the surface (see FIG. 4).

  The transfer molded article 11 thus obtained was provided with beautiful hairline eyes 7 with no appearance defects due to traces of thread-like shavings on the surface, and was excellent in design (see FIG. 5).
