Embodiment 1

[0059] A biaxially stretched polyester film (manufactured by Mitsubishi Plastics Corporation: G440E50) with a thickness of 50 μm was used as a base film, and the following composition was applied on one surface using a microgravure method so that the film thickness after drying became 0.2 μm The coating solution for the release layer is dried to form a release layer. After that, it aged at 50 degreeC for 5 days, and produced the release film.

[0061]

[0062] Next, a coating solution for a hard coat layer having the following composition was applied on the release layer of the release film using a microgravure method so that the film thickness after drying became 4.0 μm, and dried to form a hard coat layer.

Embodiment 2

[0069] In the same manner as in Example 1, a release layer and a hard coat layer were sequentially laminated on one surface of the base film.

[0070] Next, an acrylic polyol / isocyanate-based coating solution (manufactured by Toyo Ink Co., Ltd.: V425Anchor) was applied as a coating solution for an undercoat layer on the above-mentioned hard coat layer using a gravure method so that the film thickness after drying became 2 μm. , forming an undercoat. Printing is performed thereon with a predetermined coating liquid for a decorative layer to form a decorative layer. Furthermore, an adhesive layer coating liquid (manufactured by Toyo Ink Co., Ltd.: K539HP adhesive varnish) was coated using the gravure method so that the film thickness after drying became 1 μm, to form an adhesive layer. Thus, the matte tone transfer film of Example 2 was produced.

Abstract

The objective of the present invention is to provide a low-cost matte tone transfer film that can reduce the occurrence of cracks in a hard coat layer during thermal transfer to a transfer subject. The matte tone transfer film (100) has, in the given order at one surface of a substrate film (1), at least a mold release layer (2), a hard coating layer (3), and an adhesive layer (4), and the mold release layer (2) is formed from a silicone-modified acrylic urethane resin, and is a layer containing a filler.

Description

technical field [0001] The present invention relates to a matte tone transfer film and a molded article using the transfer film. More specifically, the present invention relates to a matte tone transfer film suitable for decoration of industrial products and a molded article using the transfer film. Background technique [0002] Conventionally, as a method of decorating mainly plastic molded articles, a thermal transfer method using a transfer film has been utilized instead of a direct decoration method such as painting. Many of such transfer films have a configuration in which a hard coat layer is provided in order to obtain a molded product with high surface hardness. For example, the above-mentioned transfer film generally has a structure in which a release layer, a hard coat layer, a decorative layer, and an adhesive layer are laminated in this order on one surface of a base film. [0003] As a method of thermally transferring the transfer film to the object to be trans...
