DECORATIVE SHEET AND DECORATIVE MATERIAL USING SAME, AND METHOD FOR PRODUCING DECORATIVE SHEET
The present invention relates to decorative sheets used, for example, for decorative materials, such as general fittings, and to decorative materials including the decorative sheets, and methods for producing decorative sheets; using finely divided silver for antiviral additive particles to thereby improve antiviral properties. A decorative sheet (10) is provided that includes a paper substrate, a printed pattern layer (30) arranged to face a major surface of the paper substrate, and a single-layer or multilayered surface protective layer (40) 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 (50)), 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.
