(57) Abstract: (modified with) (a) a formula (1) YR 1 m SiR 2 3-m ... (1) Hydrolysis represented by (R 1 is a C 1-8 monovalent hydrocarbon group, R 2 is a C 1-4 alkoxy group or an acyloxy group, Y is a nitrogen-containing organic group, m is 0 or 1) sex silane (a) and formula (2) R 3 n SiR 4 4-n ... (2) a hydrolyzable silane (B) represented by (R 3 is a C 1-8 monovalent hydrocarbon group, R 4 is a C 1-4 alkoxy group or an acyloxy group, and n is 0, 1 or 2) An organosilicon compound obtained by hydrolyzing a mixture containing, (b) water, (C) A coating composition comprising photo-oxidation catalyst fine particles. [Effect] Solvent removal, which is the most required in the field of paint or coating agent, is realized, and the coating film has both weather resistance and antifouling property, and is stable even in an alkaline region. |
