たものが用いられていた。2. Description of the Related Art Conventionally, as a release sheet, a sheet provided with a release layer on the surface of a base sheet has been used for process paper and the like. Process paper is used, for example, as a support sheet for a vinyl resin plastisol in the production of vinyl wallpaper, or as an oxygen shielding sheet for shielding oxygen in the air when a polyester resin liquid is cured in a polyester decorative board production process. . Further, a transfer sheet using the above release sheet is known, and the transfer sheet has a release layer on the release sheet,
It has a structure in which a transfer layer composed of a decorative layer such as a pattern, an adhesive layer, and the like is laminated, and is used to transfer the transfer layer to a transfer-receiving body and easily apply a design such as a pattern to a surface such as a molding. Have been. Conventionally, in a release sheet, silicone oil or the like has been added to the release layer in order to enhance the releasability of the release layer.

提供しようとするものである。However, in the above-mentioned conventional release sheet, the silicone oil added to the release layer bleeds out to the surface, and the peel strength changes with time. There is a problem that the sheet is peeled off when it is necessary not to peel it, and the intended purpose cannot be achieved. For example, in the case of a conventional transfer sheet using a release sheet provided with a release layer to which silicone oil has been added, it is difficult to control the releasability, and the transfer sheet is laminated on a transfer object and heated and pressed. There was a problem that the release sheet was peeled off before the transfer and transfer could not be performed at an accurate position. In order to prevent the bleed-out of the silicone oil as described above, to modify the silicone oil and polyether, etc. in order to increase compatibility with the resin that forms a functional group in the silicone oil or the resin that forms the release layer. Attempts have been made to control bleed from the release layer using silicone oil or the like. However, the above-mentioned attempt also has no effect of preventing bleeding on the surface, or conversely, the release property is completely lost, the performance as a release sheet cannot be exhibited, and a release sheet having a stable release property is required. I couldn't get it. The present invention is intended to solve the above-mentioned disadvantages of the prior art, it is possible to control the releasability of the release layer to an appropriate peel strength,
Another object of the present invention is to provide a release sheet whose releasability does not change with time and a transfer foil.

A coating composition containing 1 part by weight of a matting agent and silicone resin fine particles (Tosiba Silicon: Tospearl 120) added in the amount shown in Table 1 was applied to the surface of the base film by a reverse roll coating method. After curing at 50 ° C. for 2 days, a release layer was formed to produce a release sheet. Next, a release layer made of an acrylic resin (manufactured by Showa Ink Co., Ltd .: HAKURI 46-7) was coated on the release layer of the release sheet.

A heat-resistant ink pattern layer is formed, and a PVC / vinyl acetate (PVHS) adhesive layer is applied on the pattern layer to a thickness of 3.0 g / m 2. A transfer sheet was manufactured. The above-mentioned release layer, picture layer and adhesive layer were all formed by a gravure coating method. Using the obtained transfer sheet, it was placed in a mold and subjected to in-mold molding, and transfer was performed simultaneously with molding. As a result, good transfer was achieved in each case. The peel strength between the release sheet and the release layer of the transfer sheet was measured. Table 1 shows the measurement results.

ができる効果を有する。As described above, the release sheet of the present invention has a release layer containing silicone resin fine particles having an average particle diameter of 0.1 to 15 μm and having a network structure composed of three-dimensionally extended siloxane bonds. Compared with the conventional release sheet using silicone oil for the release layer, the silicone resin fine particles are not liquid but solid like silicone oil. As it does not move inside the release layer, it is stable because there is no risk of bleeding from the inside of the release layer to the surface over time like silicone oil and the peel strength may change over time. It is possible to exhibit improved peelability. Furthermore, since the particle size of the silicone resin fine particles can be selected and an arbitrary uneven surface can be easily formed on the surface of the release sheet, it can be used as a shaped film.
Further, when the release layer of the release sheet of the present invention contains 0.1 to 10% by weight of the matting agent, it has the effect that the irregularities on the release sheet surface can be more finely adjusted. The transfer sheet of the present invention adopts a configuration in which a transfer layer is formed on the surface of the release sheet described above, so that a stable release can be achieved as compared with a transfer sheet using a conventional silicone oil for the release layer of the release sheet. It has the effect of exhibiting the performance and being free from the problem that the transfer layer is peeled off during the transfer operation or during the preservation, so that good transfer can be performed.
