Abstract
A UV-shielding coating composition comprises (A) a dispersion in a dispersing medium of composite zinc oxide nanoparticles which are obtained by coating surfaces of zinc oxide nanoparticles with an oxide or hydroxide of Al, Si, Zr and Sn, the dispersion having a photocatalytic degradability of up to 25%, (B) a vinyl copolymer obtained from copolymerization of an alkoxysilyl-containing vinyl monomer, a UV-absorbing vinyl monomer, and another monomer, and (C) a solvent. The composition is transparent to visible light, UV-shielding, mar resistant, weatherable, and durable.
