が汚染されないことなどの利点がある。2. Description of the Related Art A transfer sheet is used as one of the means for decorating the surface of a molded product such as plastic.
The transfer sheet is formed by forming a release layer, a pattern layer, an adhesive layer, etc. on a base sheet such as a plastic film. Especially when manufacturing molded products by injection molding,
By inserting the transfer sheet into the mold, the surface of the molded product can be decorated simultaneously with the formation of the molded product. Further, the surface of the molded product can be decorated by bringing the transfer sheet into close contact with the already molded product. Unlike printing or painting, the transfer sheet decoration does not use a solvent, and thus has advantages such as not requiring a drying step and not contaminating the working environment.

品の表面の任意の部分を艶消状態とする。As a transfer sheet, there is a partial matte transfer sheet 10 in which at least a release layer 4 and an adhesive layer 6 are formed on a base sheet 1 partially having a matte layer 2 (see FIG. 8). By using the partially matte transfer sheet, the surface of the plastic molded article can be partially matted. A case will be described in which the surface of the molded product is decorated simultaneously with the formation of the molded product by the injection molding method using the partially matte transfer sheet.
The partial matte transfer sheet is inserted into a mold for injection molding in a direction in which the adhesive layer contacts the molten resin, and the resin is injected to bring the partial matt transfer sheet into close contact with the surface of the molded product. When the base sheet of the partial matte transfer sheet is peeled off, peeling occurs at the boundary surface between the base sheet and the peeling layer of the partial matte transfer sheet, and the matte layer is removed together with the base sheet. The unevenness of the matte layer is copied on the surface of the molded product, and any part of the surface of the molded product is rendered matte.

を構成する樹脂が熱可塑性樹脂や熱硬化性樹脂であり、
特に引っ掻きに対する耐性が高いものではなかった。In this case, the release layer serves as the surface of the molded product, and the surface is required to have a certain level of strength. In particular, since the matte portion is formed of fine irregularities, it is easily scratched by scratching and requires strength against scratching. However, in the above partial matte transfer sheet, the resin constituting the release layer is a thermoplastic resin or a thermosetting resin,
The resistance to scratching was not particularly high.

の発明は、上記のような欠点を解消した部分艶消転写シ
ートを提供することを目的とする。Further, as a transfer sheet having an increased surface strength, there is one in which an ultraviolet curable resin or an electron beam curable resin is used for the release layer. Since these resins have high hardness, the resistance to scratching can be improved. But,
Due to its high hardness, it has the property of cracking easily. Therefore, if you insert a partial matte transfer sheet that uses UV curable resin in the release layer into the mold and inject the resin, the partial matt transfer sheet peels when it deforms along the cavity surface of the mold. This may cause cracks in the layer. In addition, a step of irradiating ultraviolet rays or electron beams is required. Therefore, it is an object of the present invention to provide a partial matte transfer sheet in which the above drawbacks are eliminated.

Also, in the above configuration,

The matte release layer 3 is formed on the matte layer 2. Further, the gloss release layer 4 is formed on the base sheet 1. The matte release layer 3 and the matte release layer 4 are layers that are peeled off from the base sheet 1 after transfer and become the surface of the molded product 7. The matte release layer 3 and the matte release layer 4 are made of a thermoplastic resin such as an acrylic resin or a vinyl resin, or a thermosetting resin such as a urethane resin or an epoxy resin.
It is advisable to use the one to which wax is added. As the wax, polyethylene wax, polypropylene wax or the like is used. The matte release layer 3 has a higher wax content than the matte release layer 4. The wax content in the matte release layer 3 is
5 to 25% by weight is preferable. The portion where the gloss release layer 4 is formed becomes a gloss portion. If the wax content of the release layer in the glossy portion is too high, the release layer becomes dull and cloudy.
Therefore, the wax content of the gloss release layer 4 is preferably 1 to 10% by weight. The matte release layer 3 and the matte release layer 4 may be formed by an ordinary printing method such as a gravure printing method and a screen printing method. The matte release layer 3 is formed in register with the matte layer 2. The matte release layer 4 may be formed on the entire surface (see FIG. 1), or may be formed by registering the portion without the matte layer 2 (see FIG. 2).

At the same time as making the surface of the molded product 7 matt and glossy, the molded product 7
A pattern can be formed on the surface. The pattern layer 5 is formed by an ordinary printing method such as a gravure printing method and a screen printing method using a coloring ink composed of an ordinary pigment or dye and a binder, an additive and the like. It is advisable to use a coloring ink having excellent adhesion to the release layer and excellent weather resistance. The pattern layer 5 may be a single layer or a multi-layered structure having multiple colors. Further, the pattern layer 5 may be a metal thin film layer of aluminum, nickel or the like formed by a vacuum deposition method, a sputtering method, an ion plating method or the like.

The transfer layer of the transfer sheet 10 is adhered. After cooling the molded product, the mold is opened, the molded product is taken out, the base sheet 1 of the partial matte transfer sheet 10 is peeled off (see FIG. 6), and a molded product 7 having a glossy part and a matte part is obtained.

First, the adhesive layer 6 side of the partial matte transfer sheet 10 is brought into close contact with the molded product 7, and heated and pressed by a heating pad. Next, when the base sheet 1 is peeled off, the matte layer 2
Peeling occurs at the interface between the matte release layer 3 and the matte release layer 3, and peeling occurs at the interface between the base sheet 1 and the matte release layer 4. In this way, the matte portion and the glossy portion can be formed.

The fine unevenness of the matte layer is transferred to the matte release layer to form a matte portion.
Since the matte release layer contains a large amount of wax, its surface looks cloudy, but it is not noticeable because it is a matte part. Therefore, when the matte layer is removed together with the base sheet, the surface of the molded article becomes a matte part by the matte layer and a matte part by the base sheet.

It has the following effects. When the release layer and the adhesive layer are transferred to the surface of the plastic molded product by using the partial matte transfer sheet of the present invention, the wax ratio in the release layer located in the portion overlapping with the matte layer on the base sheet becomes matte. It is higher than the proportion of wax in the release layer located in the part that does not overlap the layer. Therefore, the matte portion formed on the surface of the plastic molded product is resistant to scratches. Further, since it is not necessary to use an ultraviolet curable resin or an electron beam curable resin for the release layer, even if the partial matte transfer sheet is deformed, the release layer is not cracked.
