また、射出成型法とは、金型の内面にエツチングや彫刻
によってエンボスを形成しておき、成型品を製造するの
と同時に成型品表面にエンボスを形成する方法である。Conventionally, there have been methods for producing molded products with embossing, such as a transfer method and an injection molding method. The transfer method uses a transfer material with an embossed layer containing extender pigments, matting agents, etc., or an embossed layer made of foamed material or a thick layer of ink, and performs transfer processing on the surface of the molded product. This is a method in which embossing is formed partially or completely on the surface of the product. The injection molding method is a method in which an emboss is formed on the inner surface of a mold by etching or engraving, and the emboss is formed on the surface of the molded product at the same time as the molded product is manufactured.

ボス成型品の製造方法を提供することにある。However, since the transfer method forms the embossed layer by printing, its texture is limited to the scope of printing techniques such as plate making and printing. In other words, it was not possible to perfectly express the texture of materials such as cloth and leather. In addition, the transfer process is
Since the transfer material and the molded product are overlapped and heat and pressure are applied, if the transfer material itself has a local unevenness called an embossed layer, the adhesive layer will not adhere uniformly to the molded product. If the thickness of the layer to be transferred is large, it is difficult to apply heat and pressure, resulting in poor transfer. Moreover, the total thickness of the layer to be transferred of the transfer material is generally very thin, with a total thickness of 108 m or less. For this reason, it has been extremely difficult to express unevenness within this thickness range. Furthermore, the injection molding method requires a very high mold processing cost. Further, it is not possible to form an embossing in a portion that becomes an undercut and cannot be removed from the mold. The purpose of this invention is to provide a method for manufacturing an embossed molded product, which eliminates the above-mentioned drawbacks and can form an embossed shape that faithfully reproduces the texture of the material together with a desired pattern on the surface of the molded product at a low cost. It is about providing.

このようにしてエンボス成型品を得ることができる。In order to achieve the above object, the present invention is configured as follows. That is, the method for producing an embossed molded product of the present invention involves forming a release layer, a pattern layer, and an adhesive layer on one side of a base film, and forming an embossed sheet of cloth, nonwoven fabric, leather, paper, plastic sheet, etc. on the other side. The bonded transfer material is fixed to an injection mold, the mold is closed, the molten resin is injected, and after the resin has cooled and solidified, the molded product is taken out and the base film is peeled off along with the embossed sheet. It was configured as follows. The present invention will be explained in more detail with reference to the drawings. FIG. 1 is a sectional view showing the manufacturing process of the embossed molded product of the present invention. FIG. 2 is a sectional view showing one embodiment of the transfer material used in the present invention. FIG. 3 is a sectional view showing one embodiment of an embossed molded product obtained by the present invention. 1 is a base film, 2 is a release layer, 3 is a pattern layer, 4 is a metal thin film layer, 5 is an adhesive layer, 6 is a transfer layer, 7 is an embossed sheet, 8 is a transfer material, 9 is a mold, 10 is a resin Each is shown below. First, a transfer material 8 having the layer structure described below is prepared (see FIG. 2). As the base film 1, a plastic film such as polyester, polypropylene, vinyl chloride, polyethylene, etc. is used. The appropriate thickness is 3 to 50 gm, but a thinner one is more convenient for expressing the texture of the embossed sheet 7. Transfer layers 6 such as a release layer 2, a pattern layer 3, and an adhesive layer 5 are sequentially provided on this structure film 1. ? , II M1 layer 2 is a layer for separating the transfer layer 6 from the base film 1, and is made of thermoplastic resin, natural rubber, synthetic rubber, or the like. The pattern layer 3 uses colored ink made of ordinary pigments or dyes, binders, additives, and the like. The pattern layer 3 may be a single layer or may have a multi-layer structure with multiple colors. Further, the pattern layer 3 may be one in which the metal thin film layer 4 is a single-layered layer. The metal thin film layer 4 is formed when a beautiful metal-linked look with ribs is desired for the design. The metal thin film layer 4 is preferably formed of metal such as aluminum, chromium, nickel, etc. by vacuum evaporation, ion blasting, sputtering, or the like. As a method of partially providing the metal thin film layer 4, a water-soluble resin layer is formed in the areas where the metal thin PIg layer 4 is not required, a metal layer is formed on the entire surface from above, and the water-soluble resin layer is formed by washing with water. There is a method of removing unnecessary metal layers along with the resin. Further, when providing the metal thin film layer 4, a front anchor layer and a rear anchor [Δ] may be provided before and after the metal thin film layer 4 to improve the adhesion of the metal thin film. The adhesive layer 5 is formed on the pattern layer 3 and is used to adhere each of the above layers to the transfer target. As the adhesive layer 5, a heat-resistant or pressure-sensitive resin suitable for the surface material of the plastic molded product or the like to be transferred is appropriately used. For example, if the material to be transferred is polystyrene, styrene resin or acrylic resin may be used, and if polypropylene is used, chlorinated polypropylene resin, ethylene vinyl acetate resin, or the like may be used. The release layer 2, pattern layer 3, and adhesive layer 5 are each formed by a conventional printing method such as a gravure printing method, a screen printing method, a flexographic printing method, a reverse coating method, or a roll coating method. The base film 1 on which the transfer layer 6 has been formed in this way and the embossed sheet 7 are pasted together with an adhesive to complete the transfer material 8. The emboss sheet 7 is used to give the texture of the embossing formed on the surface of the molded product, and the shape of the emboss allows the texture of various materials to be faithfully reproduced. As the embossed sheet 7, a sheet-like material such as cloth, non-woven fabric, leather, leather, plastic sheet, etc., having the embossment desired to be formed is used. Furthermore, depending on the material of the embossed sheet 7, it may be bonded to the base film 1 using static electricity without using an adhesive. Further, the transfer material 8 may be a sheet or a long sheet. Next, transfer is performed using an in-mold molding method that allows transfer to be performed simultaneously with the formation of a molded product (see Figure 1). to be installed. The surface of the embossed sheet 7 of the transfer material 8 is brought into contact with the mold 9, and the transfer layer 6 is brought into contact with the molten resin 10. To install the transfer material 8, if the transfer material 8 is long,
It is preferable to use a so-called in-mold foil feeding device that feeds the rolled transfer material 8 into the mold 9 while sequentially positioning it.Next, after the mold is closed, the molten resin 10 is fed into the mold 9.
After injecting, cooling and solidifying, wait for the mold to open and release the base film 1.
is peeled off together with the embossed sheet 7, and the transfer process is completed (see FIG. 3). In this way, an embossed molded product can be obtained.

。This invention is a transfer film in which a release N2, a pattern layer 3, and an adhesive layer 5 are formed on one side of a base film 1, and an embossed sheet 7 of cloth, nonwoven fabric, leather, paper, plastic sheet, etc. is pasted on the other side. The material 8 is used to form an embossed molded product by an in-mold molding method. Therefore, when injecting the molten resin 10, the molten resin 1
With heat and pressure of 0...the resin 10 is inserted into the embossed sheet 7 with the base film 1 in between. After the resin IO is solidified, when the base film 1 is peeled off together with the embossed sheet 7, the base film 1 of the transfer material 8 and the base film 1 of the transfer material 8 are separated. Peeling occurs between the peeling layer 2 and the transfer layer 6 adheres to the surface of the molded product.In this way, a pattern is formed on the surface of the molded product by the transfer layer 6, and the embossed sheet 7 is attached to the mold. As a result, the unevenness of the embossed sheet 7 is copied onto the surface of the molded product.

ことができる。[Example] A transfer material was prepared by dry laminating a tweed wool fabric with a polyester film having a thickness of 25 μm and a partially attached pattern using a urethane adhesive. This was fixed in an injection mold, and in-mold molding was performed by injecting acrylonitrile-styrene resin at a set temperature of 200°C. The molded product thus obtained had a pattern formed at a desired position, and the surface thereof had an embossment that revealed the pattern of the texture of the woolen fabric and the condition of each fiber. 1. A molded product was obtained in the same manner as in Example 1, using linen fabric as the embossed sheet. The surface of the molded product had embossments that revealed the texture of the hemp fabric and the texture of the fibers. A molded product was obtained in the same manner as in Example 1, using cowhide as the embossed sheet. The surface of the molded product had embossments that revealed the grain pattern and texture of cowhide. [Effect of the invention] This invention forms a release layer, a pattern layer, and an adhesive layer on one side of a base film, and laminates an embossed sheet of cloth, nonwoven fabric, leather, yam, plastic sheet, etc. on the other side. It is configured to form an embossed molded product by an in-mold molding method using a transfer material. Therefore, the textures of various materials can be faithfully reproduced, and designs can be simultaneously formed at arbitrary positions. In addition, the emboss is formed as the molten resin pushes the base film into the embossed sheet, and there is no problem in removing the molded product from the mold, so undercut-like embossing can also be created on the sides of the molded product. can be formed.
