Abstract:
An inorganic oxide dispersion containing an organic solvent, and inorganic oxide particles surface-treated with at least one of a hydrolyzate and a partial condensate of an organosilane compound represented by formula (I), the inorganic oxide particles being dispersed in the organic solvent: (R10)m—SI(X)4-m (I) as defined herein, the surface treatment of the inorganic oxide particles being carried out 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: R3OH in which R3 represents an alkyl group having 1 to 10 carbon atoms, and a compound represented by formula: R4COCH2COR5 as defined herein, as a ligand.
