Abstract
There is disclosed a photocatalyst-coated body which is superior in weather resistance, noxious gas decomposability, and various coating properties (such as ultraviolet absorptivity, transparency and film strength) while preventing corrosion of a substrate (in particular an organic substrate), and a photocatalyst coating liquid therefor. The photocatalyst-coated body comprises a substrate and a photocatalyst layer provided on the substrate. The photocatalyst layer comprises photocatalyst particles of 1 part or more by mass and less than 20 parts by mass; inorganic oxide particles of 70 parts or more by mass and less than 99 parts by mass; and a hydrolyzable silicone of zero parts or more by mass and less than 10 parts by mass, provided that a total amount of the photocatalyst particles, the inorganic oxide particles and the hydrolyzable silicone is 100 parts by mass.
