Method for producing decorative sheet, decorative sheet, decorative member, and ink for forming pattern portion for gloss mat expression

Abstract

Provided is a method for producing a decorative sheet which has a more realistic texture, expresses a favorable realistic hue, and is excellent in post-processing resistance to post-processing such as V-groove bending. To this end: on one surface of a colored thermoplastic resin layer (2), a picture layer (5) with a picture, a transparent thermoplastic resin layer (6) containing a nano-sized nucleating agent, and a surface protective layer (7) are layered in this order; a pattern layer (8a) is formed using a colorless or light-colored ink and a material with a greater light absorbability of light of a predetermined wavelength than the colored thermoplastic resin layer (2) by arranging, on the other surface of the colored thermoplastic resin layer, a pattern portion for gloss mat expression (3), which is a light-absorbing region, to match with the picture; then irradiating light in which power of light of a predetermined wavelength is greater than power of light of other wavelength is emitted; and then an embossed portion (7a) is formed by pressing an embossing plate for forming an embossed shape against the surface protective layer (7).
