The colored layer is formed on the peeling layer 2. As the material of the colored layer, polyvinyl resin, polyamide resin, polyester resin, acrylic resin, polyurethane resin, polyvinyl acetal resin, polyester urethane resin, cellulose ester resin, resin such as alkyd resin is used as a binder. It is preferable to use a colored ink containing a pigment or dye of an appropriate color as a colorant. As a method for forming the colored layer, there are a printing method such as an offset printing method, a gravure printing method and a screen printing method, and a coating method such as a gravure coating method, a roll coating method and a spray coating method. In particular, an offset printing method or a gravure printing method is suitable for performing multicolor printing and gradation expression.

The metal thin film layer is formed on the peeling layer 2. If there is a colored layer, it is formed on the colored layer. The metal thin film layer is provided to express a metallic luster itself or a hairline pattern having metallic luster. The metal thin film layer is formed by a vacuum deposition method, a sputtering method, an ion plating method, a plating method or the like. Depending on the metallic luster color you want to express, the metal thin film layer can be made of aluminum, nickel, gold, platinum,
Chrome, iron, copper, tin, indium, silver, titanium,
Metals such as lead and zinc, alloys or compounds thereof are used. As a method of partially forming the metal thin film layer, after forming a solvent-soluble resin layer on a portion where the metal thin film layer is not necessary, a metal thin film is formed on the entire surface of the resin thin film layer and washed with a solvent to dissolve the solvent. There is a method of removing an unnecessary metal thin film together with the resin layer. Often used as a solvent is water or an aqueous solution. Further, as another method of partially forming the metal thin film layer, a metal thin film is formed on the entire surface, then a resist layer is formed on a portion where the metal thin film is to be left, and etching is performed with an acid or an alkali to form a resist. There is a method of removing the layer.

Further, a pre-anchor layer may be formed in order to improve the adhesion between the peeling layer 2 or the coloring layer and the metal thin film layer.

The layer structure of the transfer material 11 is an example of the transfer material 11, and other layer structures may be used. For example, when the pattern layer 3 also has the function of the peeling layer 2, the peeling layer 2 can be omitted. When the pattern layer 3 also has the function of the adhesive layer 4, the adhesive layer 4 can be omitted.

A pattern 8 is formed on one surface of a molded product made of the first transparent resin 7 by using the transfer material 11 having the above-mentioned layer structure.

A transparent material is used as the first transparent resin 7. As the transparent resin, resins such as acrylic resin, polyester resin, polycarbonate resin, ABS resin, polystyrene resin, AS resin, polyoxymethylene copolymer resin and polypropylene resin can be used. Moreover, you may use what added the coloring agent etc. to these resins.

Next, a transfer method using the transfer material 11 will be described.

The adhesive layer 4 side of the transfer material 11 is brought into close contact with the surface of the molded product. Next, using a transfer machine such as a roll transfer machine or an up-down transfer machine equipped with a heat-resistant rubber-like elastic material such as silicon rubber, a temperature of about 80 to 260 ° C and a pressure of 50 to 200 kg /
Heat and pressure are applied from the base material sheet 1 side of the transfer material 11 through the heat-resistant rubber-like elastic body set to the condition of about m ² . The adhesive layer 4 adheres to the surface of the molded product by heating and pressing. When the base sheet 1 is peeled off after cooling, peeling occurs at the interface between the base sheet 1 and the release layer 2, and transfer is completed. Also,
When a release layer is provided on the base sheet 1, the base sheet 1
When peeled off, peeling occurs at the boundary surface between the release layer and the peeling layer 2, and the transfer is completed. When the base sheet 1 is peeled off, the peeling layer 2 may cause delamination or the release layer may cause delamination.

Next, a simultaneous molding transfer method using an injection molding method using the transfer material 11 will be described. The molding simultaneous transfer method is also called an in-mold method. The simultaneous molding transfer method is a method in which the transfer material 11 is sandwiched in advance in a mold such as injection molding or extrusion molding, and transfer is performed by molding heat and pressure simultaneously with molding of the molded product. According to the molding simultaneous transfer method, the pattern 8 can be more rationally formed by the transfer material 11. Further, even when the shape of the portion forming the pattern 8 of the molded product has unevenness instead of a flat surface, the pattern 8 can be easily formed by the transfer material 11 (see FIG. 3).

The molding die is composed of a male die 5 and a female die 6, and a void is formed by closing both the die.

First, the transfer material 11 is fixed in the mold.
At this time, the individual transfer materials 11 may be fed one by one, or the long transfer material 11 may be intermittently fed. Further, it is preferable to use a film feeding device provided with a positioning mechanism for detecting the position of the transfer material 11 with a sensor so that the pattern 8 of the transfer material 11 and the mold are in register.

Next, the mold is closed and molten resin is injected into the mold from a gate provided in the male mold 5 to form a molded product, and at the same time, the adhesive layer 4 of the transfer material 11 is adhered to the surface of the molded product. To do.

After cooling the molded product, the mold is opened to take out the molded product, and the base sheet 1 of the transfer material 11 is peeled off to complete the transfer.

A pattern 8 is formed on the molded product made of the first transparent resin 7.
Although the method of using the transfer material 11 has been described as the means for providing the pattern, an adhesive material may be used to provide the pattern 8.

As the patch material, one having the pattern layer 3, the adhesive layer 4, etc. on the base sheet 1 is used. The patch is
Unlike the transfer material 11, the base sheet 1 is not peeled off after being bonded to a molded product made of the first transparent resin 7.
That is, in the case of the transfer material 11, the release layer 2, the pattern layer 3, and the adhesive layer 4 remain on one surface of the molded product made of the first transparent resin 7, while in the case of the adhesive material, the first layer Transparent resin 7
The base sheet 1, the pattern layer 3, and the adhesive layer 4 remain on one surface of the molded product made of.

As the base sheet 1, the same material as the transfer material 11 may be used. However, the base sheet 1 needs to have high adhesiveness to the second transparent resin 9, and an adhesive may be applied to the back surface of the base sheet 1. Further, the base sheet 1 does not need to have releasability from the design layer 3. As the pattern layer 3, the same material as the transfer material 11 may be used. As the adhesive layer 4, the same material as the transfer material 11 may be used.

In order to adhere the adhesive material to the molded product made of the first transparent resin 7, heating and pressurization are performed as in the case of the transfer material 11. The only difference from the transfer material 11 is that the base sheet 1 is not peeled off after adhesion. Further, as in the simultaneous molding transfer method, the patch can be placed in the mold and the patch can be bonded simultaneously with the molding of the molded product made of the first transparent resin 7. In this case, depending on the shape of the molded product, the patch may be pre-formed into an uneven shape along the inner surface of the mold in advance.

The molded article made of the first transparent resin 7 having the pattern 8 formed on one surface obtained by the above-mentioned means is
The transfer sheet 11 or the adhesive sheet having the background layer 10 is placed on the female die 6 of the insert molding die so that the side faces the male die 5, and the base sheet 1 of the transfer material 11 is used as the male die 5 of the die. So that the background layer 10 of the patch or the base sheet 1 faces the male mold 5 of the mold (see FIG. 1),
After the mold is closed, the second transparent resin 9 is injected into the space between the molded article made of the first transparent resin 7 and the transfer material 11 (see FIG. 2), so that By sandwiching the pattern 8 with the second transparent resin 9, a molded product (see FIGS. 4 to 5) having the background layer 10 on the outside of the second transparent resin 9 can be obtained.

The insert molding die is used for ordinary injection molding, and is capable of arranging a molded product made of the first transparent resin 7 and the transfer material 11 or the adhesive material. I wish I had it.

Using the insert molding die as described above, a molded article made of the first transparent resin 7 having a pattern 8 formed on one side is prepared by inserting the insert molding metal so that the pattern 8 side faces the male die 5. It is placed in the female mold 6 of the mold.

Deploy. The background layer 10 may be configured similarly to the pattern layer 3. The background layer 10 is a pattern layer 3 that constitutes characters, etc.
Since it is positioned on the rear side to make letters and the like stand out, it is preferable to form it entirely (see FIG. 7).

After the mold is closed, the second transparent resin 9 is injected into the gap between the molded product made of the first transparent resin 7 and the transfer material 11 (see FIG. 2). As the second transparent resin 9, the same transparent material as the first transparent resin 7 is used.

In this way, the pattern 8 is sandwiched between the first transparent resin 7 and the second transparent resin 9, and the second transparent resin 9 is inserted.
A molded article having the background layer 10 on the outside of the can be obtained (see FIGS. 4 to 5). The design 8 may be configured to be flat (see FIG. 4), or the design 8 may be configured to be three-dimensional (see FIG. 5). If the design 8 is three-dimensional,
The sense of luxury can be increased.

Further, if a two-color molding method is used in which the pattern 8 is formed on the molded product made of the first transparent resin 7 and the molding is immediately performed by the second transparent resin 9, it is more rational. A molded product with a picture can be obtained.

The method utilizing the two-color molding method means the pattern layer 3
A transfer product 11 or a sticking material having the above is placed in a mold, and the first transparent resin 7 is injected to form a molded product made of the first transparent resin 7 having a pattern 8 formed on the surface on the male mold 5 side. Then, a molded product made of the first transparent resin 7 is formed into the female mold 6.
The male mold 5 is replaced with a molded product made of the first transparent resin 7 having a void on the side of the pattern 8 while being held in the background layer 10
So that the base sheet 1 of the transfer material 11 faces the male mold 5 of the transfer material, or the adhesive material has the background layer 10 of the transfer material or the base sheet 1 of the transfer material 11 has a male mold 5 of the mold.
The second transparent resin 9 is injected into the gap between the transfer material 11 and the molded product made of the first transparent resin 7.

More specifically, a method using the two-color molding method will be described.

As molds used in the two-color molding method, two female molds 6 having the same shape and two male molds 5 having different shapes are prepared. The first female mold and the first male mold form a first void, and the second female mold and the second male mold form a second void that is larger than when the first male mold is used. . Further, by exchanging the first male mold and the second male mold, a second void is formed by the second male mold and the first female mold, and a first void is formed by the first male mold and the second female mold. To be able to form.

First, the transfer material 11 or the adhesive material is placed between the first female mold and the first male mold, and the mold is closed. Transfer material 11
In the case of using, a transfer material feeding device is used to position the transfer material 11 at a predetermined position of the first male mold, and a suction device, a compressed air device, a heating device, etc. are used before injection molding is performed.
The transfer material 11 may be brought into close contact with the convex portion or the concave portion of the first male mold. When the patch is used, the patch may be preformed in advance and the patch may be placed at a predetermined position of the first male mold by using the patch insertion device.

Next, the first transparent resin 7 is injected into the first void and the first transparent resin 7 is cooled and solidified to obtain a molded article having the design 8. When the transfer material 11 is used,
