    摘要： A coating composition which is excellent in water resistance, weatherability and durability and can maintain its appearance for a prolonged period of time can be provided. A coating composition comprising a coating component and a photocatalyst containing calcium phosphate and titanium oxide is disclosed. As the photocatalyst, use is made of titanium oxide particles partially covered thereon with calcium phosphate, or porous body coated thereon with a film of titanium oxide, the film of titanium oxide being further covered partially thereon with calcium phosphate. The crystal form of titanium oxide is preferably anatase. The organic coating includes vinyl-type synthetic resin emulsions, and the inorganic coating is e.g. a solution containing a metal alkoxide for forming a film by a sol-gel method.
