Abstract: To obtain a decorative sheet having excellent fingerprint resistance of the decorative sheet surface, a decorative plate, and a method for producing a decorative sheet. A decorative sheet includes: a primary film layer; a colored pattern layer provided on one surface of the primary film layer; and a first surface protective layer provided on the surface on the side opposite to the primary film layer of the colored pattern layer, having a core part and ridge-like parts provided to project in a ridge-like shape from one surface of the core part, and having an irregular shape formed on the surface. The first surface protective layer of the decorative sheet is formed by irradiating a surface of an applied ionizing radiation curable resin with a first ionizing radiation having energy capable of cleaving a polymer chain of the ionizing radiation curable resin, to shrink the surface of the ionizing radiation curable resin, and form an irregular shape on the surface of the ionizing radiation curable resin, and irradiating the shrunk ionizing radiation curable resin with a second ionizing radiation curing the ionizing radiation curable resin to cure the ionizing radiation curable resin.

Abstract: There are provided a decorative sheet having excellent fingerprint resistance of the surface of the decorative sheet, a decorative board, a method for manufacturing a transfer master plate, and a method for manufacturing a decorative sheet. The decorative sheet includes: a base material layer; a colored pattern layer provided on one surface of the base material layer; and a first surface protective layer provided on the surface on the side opposite to the base material layer of the colored pattern layer and having irregular shapes on the surface. The decorative sheet is formed using a transfer master plate which is a resin material having irregular shapes for master plate on the surface formed by irradiating the surface of an applied ionizing radiation curable resin with a first ionizing radiation having energy capable of cleaving a polymer chain of the ionizing radiation curable to shrink the surface of the ionizing radiation curable resin, forming the irregular shapes for master plate on the surface of the ionizing radiation curable resin, irradiating the shrunk ionizing radiation curable resin with a second ionizing radiation curing the ionizing radiation curable resin to cure the ionizing radiation curable resin.
