A coating composition comprising (A) a hydrolyzate or partial condensate, or both, of an organosilane compound represented by the following formula (1),wherein R1 is a hydrogen atom or a monovalent organic group having 1-8 carbon atoms, R2 is an alkyl group having 1-5 carbon atoms or an acyl group having 1-6 carbon atoms, and n is an integer from 0 to 2, (B) at least one ultraviolet ray absorbing component selected from the group consisting of fine semiconductor particles, semiconductor sols, and organic compounds having ultraviolet ray absorbing capability, and (C1) water and/or an organic solvent. The coating composition exhibits excellent storage stability and produces coating films with good appearance, superior adhesion properties, weather resistance, high hardness, and superb UV absorbing capability.
