Patent ID: 8916266

Claim:
A coating composition comprising (A) a metal oxide particle having a number average particle size of 1 nm to 400 nm; (B) a polymer particle; and (C) at least one hydrolyzable silicon compound, wherein 15 mass % or less of the component (B) is an aqueous-phase component represented by the expression (I), where (I) is the aqueous-phase component (%)=(dry mass of a filtrate obtained by filtering the component (B) at a molecular cutoff of 50,000)×(100−total mass of solid content)/(mass of the filtrate−dry mass of the filtrate)×100/the total mass of solid content; and wherein the hydrolyzable silicon compound is selected from the group consisting of compounds represented by the following formulas (1), (2) and (3): R 1 n SiX 4-n (1) wherein R 1 represents a hydrogen atom, or an alkyl group, alkenyl group, alkynyl group or aryl group having 1 to 10 carbon atoms and optionally having a halogen group, a hydroxy group, a mercapto group, an amino group, a (meth)acryloyl group or an epoxy group; X represents a hydrolyzable group; and n is an integer of 0 to 3; X 3 Si—R 2 n —SiX3 (2) wherein X represents a hydrolyzable group; R 2 represents an alkylene group or phenylene group having 1 to 6 carbon atoms; and n is 0 or 1; and R 3 —(O—Si(OR 3 ) 2 ) n —OR 3 (3) wherein R 3 represents an alkyl group having 1 to 6 carbon atoms; and n is an integer of 2 to 8.
