Abstract

A coating composition is provided comprising (A) 1-50 parts by weight of surface-treated titanium oxide comprising core/shell type microparticles each consisting of a titanium oxide core and a silicon oxide shell, which are treated with two surface treating components having formula (I): R<1>Si(OR<2>)<3>and formula (II): (R<3>R<4>2 Si)<2>NH, (B) 100 parts by weight of a vinyl copolymer obtained from copolymerization of (b-1) an alkoxysilyl-containing vinyl monomer, (b-2) a UV-absorbing vinyl monomer, and (b-3) another monomer, and (C) a solvent. A cured film of the composition has improved mar resistance and UV shielding while maintaining visible light transparency.
