Patent ID: 8221878

Claim:
A photocurable coating composition, comprising: (1) porous, hollow, or both porous and hollow inorganic oxide fine particles (A), (2) a hydrolytic condensate of a bissilane compound (B), a cohydrolytic condensate of a bissilane compound (B) and another hydrolyzable organosilicon compound (D), or both, the bissilane compound (B) having the formula: X n R 3-n Si—Y—SiR 3-n X n (B) wherein Y is a divalent organic group which is optionally fluorinated or a divalent organic group which optionally comprises an aromatic ring, R is a monovalent organic group, X is OH or a hydrolyzable group, and n is 1, 2 or 3, (3) a compound capable of generating an acid upon light exposure, and (5) a (co)hydrolytic condensate of a reactive dimethylsiloxane (C), an organosilicon compound comprising the reactive dimethylsiloxane (C), or both, in an amount of from 1 to 25% by weight based on solids in the coating composition, the dimethylsiloxane (C) having the formula: (R 1 O) 3 Si—R 2 —((CH 3 ) 2 SiO) x —Si(CH 3 ) 3 (C) wherein R 1 is methyl, ethyl, propyl or butyl, R 2 is oxygen or CH 2 CH 2 , and x is an integer of from 5 to 50.
