Title:
DECORATIVE SHEET, DECORATIVE PLATE, AND METHOD FOR PRODUCING DECORATIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2021/149480
Kind Code:
A1
Abstract:
Provided are a decorative sheet having excellent fingerprint resistance on the decorative sheet surface, a decorative plate, and a method for producing the decorative sheet. The decorative sheet is provided with: a base material layer; a colored pattern layer provided on one surface of the base material layer; and a first surface protection layer that is provided on the surface of the colored pattern layer on the opposite side from the raw material layer, that includes a core section and ridge sections provided protruding in a ridge-like shape from one surface of the core section, and that has an uneven shape formed on the surface thereof. The first surface protection layer of the decorative sheet is formed by irradiating the surface of an applied ionizing radiation-curable resin with first ionizing radiation having an energy that makes it possible to cut the polymer chains of the ionizing radiation-curable resin, thereby shrinking the surface of the ionizing radiation-curable resin, forming an uneven shape on the surface of the ionizing radiation-curable resin, irradiating the shrunk ionizing radiation-curable resin with second ionizing radiation for curing the ionizing radiation-curable resin, and curing the ionizing radiation-curable resin.
