Title:
DECORATIVE SHEET, DECORATIVE BOARD, METHOD FOR MANUFACTURING TRANSFER MASTER PLATE, AND METHOD FOR MANUFACTURING DECORATIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2021/199556
Kind Code:
A1
Abstract:
Provided are: a decorative sheet which has a surface having excellent fingerprint resistance; a decorative board; a method for manufacturing a transfer master plate; and a method for manufacturing a decorative sheet. The decorative sheet is provided with: a base sheet layer; a colored pattern layer which is arranged on one surface of the base sheet layer; and a first surface protection layer which is arranged on a surface of the colored pattern layer which is opposed to the base sheet layer and has an uneven form on the surface thereof. The decorative sheet is formed using a transfer master plate which is a resin material having an uneven form for a master plate on the surface thereof, and which is formed by irradiating a surface of an applied ionizing-radiation-curable resin with a first ionizing radiation having an energy sufficient to cleave a polymer chain in the ionizing-radiation-curable resin to shrink the surface of the ionizing-radiation-curable resin thereby forming an uneven form for a master plate on the surface of the ionizing-radiation-curable resin and then irradiating the shrunk ionizing-radiation-curable resin with a second ionizing radiation capable of curing ionizing-radiation-curable resins to cure the ionizing-radiation-curable resin.
