<P>PROBLEM TO BE SOLVED: To provide a photocatalyst composite material which has superior alga-proof property and good performance when used for decomposing toxic gas such as NOx and is excellent also in weatherability with respect to a photocatalyst-coated body exhibiting effects excellent in toxic substance decomposition performance, anti-fouling property and suppression for proliferation of fungus or alga. <P>SOLUTION: In the photocatalyst-coated body comprising a substrate, an intermediate layer disposed on the substrate and a photocatalyst layer disposed on the intermediate layer, the intermediate layer comprises an organic mildew-proof agent and the photocatalyst layer consists of: photocatalyst particles of 1 pts.mass or more and less than 20 pts.mass; inorganic oxide particles of more than 70 pts.mass and equal to or less than 99 pts.mass; and dry material of hydrolyzable silicone of 0 pts.mass or more and less than 10 pts.mass in terms of silica so that the total amount of the photocatalyst particles, inorganic oxide particles and dry material of hydrolyzable silicone in terms of silica amounts to 100 pts.mass. <P>COPYRIGHT: (C)2010,JPO&INPIT |
