Abstract:
A heat modified, inorganic film-forming coating composition prepared by heat treating at 80Â° to 100Â° C. or autoclaving at 80Â° to 200Â° C. an inorganic film-forming coating composition to form titanium oxide fine particles, the inorganic film-forming coating composition being prepared by a method, said method comprising adding titanium monomer and/or a low condensation product thereof containing the group hydrolyzed to form hydroxyl group into a mixture of hydrogen peroxide water with water in such an amount that the titanium monomer and/or the low condensation product thereof may be hydrolyzed, followed by reacting to form a hydroxyl group-containing titanium compound and immediately followed by coordinating the hydroxyl group-containing titanium compound with hydrogen peroxide to form a chelate solution, and obtaining an inorganic film-forming coating composition comprising the chelate solution, the titanium monomer containing the group hydrolyzed to form hydroxyl group being represented by formula Ti(OR)4, wherein R is same or different, and represents an alkyl group having 1 to 5 carbon atoms.
