PURPOSE: To improve the light fastness, weather resistance, etc., of a coating film, by incorporating a salt of a particular metal selected from Co, Pd, Ag, Cr, etc., into a binder vehicle of a coating paint contg. titanium oxide particles. n CONSTITUTION: A salt of a metal selected from cobalt, palladium, silver, chromium, lead copper, vanadium, platinum, tungsten, mercury, lanthanum, bismuth, and molybdenum (e.g., vanadium trichloride, cobalt chloride) is provided. One or more members selected from such salts are incorporated into the binder vehicle of a coating compsn. contg. titanium oxide particles having a particle size of about 1W100mμ. Since the incorporated metal salt works as a catalyst poison against the photocatalytic activity of titanium oxide, the light fastness, weather resistance, etc., of a coating film can be improved. n COPYRIGHT: (C)1988,JPO&Japio |
