Abstract: Decorative sheets used for decorative materials, such as for general fittings, and methods for producing, and prevents discoloration due to contact between chlorine and silver, including at least a polyvinyl chloride resin layer, a pattern layer, and a surface protective layer, the surface protective layer contains silver components including silver and is free from chlorine-containing components. The surface protective layer may be composed of a plurality of laminated layers that include at least one layer containing the silver components; the laminated layers of the surface protective layer may include at least one layer disposed adjacent to the polyvinyl chloride resin layer and being free from silver components; the silver components may each be supported on an inorganic substance; the surface protective layer may have a cross-linked structure; and the cross-linked structure of the surface protective layer may be formed by use of ultraviolet light or an electron beam.

Abstract: A decorative sheet and a decorative member having both excellent antiviral properties and high processability. The decorative sheet is provided with a colored layer, a pattern layer, and a surface protective layer, wherein: the surface protective layer is provided with a first surface protective layer containing an antiviral agent and at least one of a heat-curable resin, an ultraviolet-curable resin, and an electron beam-curable resin; the addition amount of the antiviral agent is 0.2% by mass or more and 10% by mass or less with respect to the surface protective layer; and the average particle size of the antiviral agent is 1 μm or more and 10 μm or less.

Abstract: A decorative sheet is provided that includes a paper substrate, a printed pattern layer arranged to face a major surface of the paper substrate, and a single-layer or multilayered surface protective layer arranged to face the pattern layer, the surface protective layer comprising a coating layer as an outermost layer of the decorative sheet, the coating layer being comprised of a coating containing antiviral additive particles (e.g., antiviral agent), the antiviral additive particles comprising finely divided silver. Further, the coating layer may contain a silicone-based component or a fluorine-based component, which imparts contamination resistance to the coating layer; the amount of the antiviral additive particles in the coating layer may be 0.2 mass % or more and 12 mass % or less relative to the total solid content of the coating layer; and the thickness of the coating layer may be 3 μm or more.
