Abstract

PURPOSE:To obtain a decorative sheet with an expression being changable by the angle of light and angle of sight by providing a bright ink layer with a fine uneven shape on the outermost surface of a thermosetting resin decorative sheet. CONSTITUTION:A thermosetting resin decorative sheet with a fine uneven shape on the surface is prepd. by providing a polyolefin resin layer on a release sheet, providing a fine uneven shape on the surface of the resin layer, forming a printed layer on the uneven face by using a bright ink, laminating the thus obtd. transfer sheet on a thermosetting impregnating paper, hot-pressing and molding them and peeling the release sheet. As the bright ink layer, such a product that tightly adheres with a transfer film in such a extent that a foil does not fall down before molding and it is easy to be peeled off after hot press molding and tightly adheres with the thermosetting resin and has surface properties is especially advantageous. Practically, a transfer film (figure A) consisting of a release layer 1 on which a fine uneven shape 3 is provided and a bright ink layer 2 is laminated on a thermosetting resin layer 5 which is a base material 4 of the decorative sheet and is hot pressed and molded (figure B) and then, the release layer 1 is peeled off (figure C).

However, in printing with ordinary ink as described in 1.L, the ink layer does not come into close contact with the melamine, and the surface properties as a decorative board cannot be obtained. In addition, even when using the above-mentioned embossed pattern sheet, since the polyolefin resin has poor heat and pressure resistance,
The surface of the product tends to become dull. Furthermore, in the last known technique mentioned above, even if glitter printing is applied to titanium paper, the final product does not exhibit glitter due to the influence of the melamine-impregnated overlay paper, and there are disadvantages such as no change due to differences in the angle of the light beam. There was.

The four glittering layers described in "-" can be provided by a transfer method, and preferably, a transfer sheet is formed by laminating a base material Filno and a transfer layer having a release layer on the base film side on the surface thereof. A transfer film is used in which the release layer is a base film, and from the side, the first release layer is made of a one-component urethane ink, and the second release layer is made of a two-part urethane ink. This configuration of the release layer is particularly preferred in the case of polyester film (PET). However, in the case of 2-polypropylene-1 non-film, this film has poor mold releasability, so the first release layer made of 1-wave type urethane ink can be omitted, and even a 2-component urethane ink layer can be used. It can be peeled off.

Before molding, the glitter ink layer adheres to the transfer film (imprinted FILNO) to the extent that the foil does not fall off, and after hot-press molding, it is easily removable, and it also adheres closely to the thermosetting resin, improving surface properties. It is particularly advantageous to have Examples of bright pigments include metal powders such as aluminum powder, copper powder, and brass powder;
Pigments with metallic luster such as metal flakes and cut pieces of metallized synthetic resin film, pigments with pearlescent luster or interference such as titanium dioxide-coated mica, fish scale foil, and hismuth acid chloride are used. A two-component polyurethane ink is particularly suitable as the glitter ink.
