Patent ID: 8029855

Claim:
A coating process comprising: producing a dispersion of inorganic oxide particles dispersed in an organic solvent by a process comprising: (1) surface treating inorganic oxide particles with at least one of a hydrolyzate and a partial condensate of an organosilane compound represented by formula (I): (R 10 ) m —Si(X) 4−m (I) wherein R 10 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; X represents a hydroxyl group or a hydrolyzable group; and m represents an integer of 1 to 3, in an organic solvent comprising 30% by volume or less of ketone solvent in a presence of at least one of (a) an acid catalyst and (b) a metal chelate compound having Zr, Ti or Al as a center metal and at least one of an alcohol represented by formula: R 3 OH in which R 3 represents an alkyl group having 1 to 10 carbon atoms, and a compound represented by formula: R 4 COCH 2 COR 5 in which R 4 represents an alkyl group having 1 to 10 carbon atoms; and R 5 represents an alkyl group having 1 to 10 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, as a ligand, and (2) replacing the organic solvent used for the surface treatment with an organic solvent comprising 50% by volume or more of ketone solvent; preparing a coating composition comprising a film-forming composition comprising a compound having an ethylenically unsaturated group and the dispersion of inorganic oxide particles dispersed in an organic solvent; and applying the coating composition; wherein the inorganic oxide particles are hollow silica particles.
