Abstract
A coating composition for use in a hydrophilic treatment comprising (A) an organic-inorganic composite reaction product prepared by a process which comprises reacting 100 parts by weight, as the solid content, of (i) a water-dispersible silica with 0.1 to 10 parts by weight of (ii) a polymerizable vinylsilane monomer containing hydrolyzable alkoxysilane group to form an aqueous polymerizable vinyl group-containing silica dispersion and then reacting the aqueous polymerizable vinyl group-containing silica dispersion with (iii) a mixture of polymerizable unsaturated monomers other than the above (ii); (B) a curing agent and (C) a hydroxyl group-containing polyester resin, the ratio of the component (A) to the component (B) being in the range of 99 to 50:1 to 50 as the solid content weight ratio, and the amount of the component (C) being in the range of 5 to 60% by weight based on the solid content in the composition comprising the component (A), (B) and (C); a hydrophilic-treating method; and hydrophilically treated heat exchanger fins.
