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.

Decorative sheet and decorative member

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.

Decorative sheet and method for producing the same

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.

Decorative sheet, decorative material including the same, and method for producing decorative sheet

A decorative material includes a substrate and a decorative sheet laminated on at least one surface of the substrate, the decorative sheet including a printing substrate layer, a pattern layer laminated on one surface of the printing substrate layer, and a surface protective layer laminated on a surface of the pattern layer opposite to a surface facing the printing substrate layer, and the surface protective layer having an antiviral agent and a fluorochrome added thereto.
