Photocatalyst-coated body, coating composition for the same, and process for producing photocatalyst-coated body

Abstract

A photocatalyst-coated body includes a substrate with an organic material as a surface thereof, a photocatalyst layer with interstices between the particles in the layer and an intermediate layer provided between the substrate and the photocatalyst layer. The photocatalyst layer includes photocatalyst particles in a range of 1 part≦x<20 parts by mass, inorganic oxide particles in a range of 70 parts≦y<99 parts by mass, and a dried substance of a hydrolyzable silicone in a range of zero parts≦z<10 parts by mass, provided that a total amount of the photocatalyst particles, the inorganic oxide particles, and the dried substance of the hydrolyzable silicone is 100 parts by mass in terms of silica. The intermediate layer comprising a silicone-modified resin, wherein the silicone-modified resin includes silicon atom in an amount of 0.2% by mass or more and less than 16.5% by mass.
