COPING
PROBLEM TO BE SOLVED: To provide a coping which can exhibit antiviral performance even in low illuminance environment and can suppress lowering of the antiviral performance by abrasion.SOLUTION: A coping 1 has a hard core material 2 and a coated body 3 which is provided outside of the core material 2 and contains a thermoplastic resin as a main component, where the coated body 3 is formed of a base 4 covering the core material 2 and an outer layer portion 5 which covers the base 4 and forms the surface of the coated body 3, the outer layer portion 5 is formed of a photocatalyst-containing resin composition obtained by mixing a photocatalytic material with a resin material containing the thermoplastic resin as a main component, the photocatalytic material contains a copper compound-supported titanium oxide in which a divalent copper compound is supported on titanium oxide, the copper compound-supported titanium oxide has an average primary particle size of 50-500 nm and an average secondary particle size of 200-1,000 nm, and a content of the photocatalytic material in the photocatalyst-containing resin composition is more than 0.8 mass% and 30 mass% or less.SELECTED DRAWING: Figure 1
【課題】 低照度環境でも抗ウイルス性能を発揮でき、且つ摩耗による抗ウイルス性能の低下を抑制できる笠木を得る。【解決手段】硬質の芯材２と、芯材２の外側に設けられ且つ熱可塑性樹脂を主成分とする被覆体３とを備える笠木１であって、被覆体３は、芯材２を覆う基部４と、基部４を覆うと共に被覆体３の表面を成す外層部５とからなり、外層部５は、熱可塑性樹脂を主成分とする樹脂材料に光触媒材料を混合した光触媒含有樹脂組成物により形成され、光触媒材料は、酸化チタンに２価銅化合物を担持した銅化合物担持酸化チタンを含み、銅化合物担持酸化チタンは、平均１次粒子径が５０〜５００ｎｍ、平均２次粒子径が２００〜１０００ｎｍであり、光触媒含有樹脂組成物中における光触媒材料の含有量が、０．８質量％を超えて３０質量％以下である。【選択図】 図１
