Abstract:
1. A silicone coating composition for forming a mar resistant surface film comprising a silicone resin (I) which is obtained by cohydrolytic condensation of: (A) at least one hydrolyzable organosilicon compound having the general formula (1): wherein R 11 , R 12 , R 13 , and R 14 are each independently a hydrogen atom, alkyl group of 1 to 6 carbon atoms or phenyl group, Z 1 and Z 2 are each independently selected from the class consisting of a halogen atom, alkoxy group of 1 to 3 carbon atoms, alkoxyalkoxy group of 2 to 4 carbon atoms, acyloxy group of 1 to 6 carbon atoms, alkenoxy group of 1 to 6 carbon atoms, and isocyanate group, Y is an oxygen atom or alkylene group of 2 to 10 carbon atoms, a and b are each independently an integer of 1 to 3, and c is an integer of 1 to 30, and/or a partial hydrolytic condensate thereof, and (B) at least one alkoxysilane having the general formula (2): wherein R 1 and R 2 are each independently hydrogen or a substituted or unsubstituted monovalent hydrocarbon group, R 3 is an alkyl group of 1 to 3 carbon atoms, m and n are each independently an integer of 0 or 1, and m+n is 0, 1 or 2, and/or a partial hydrolytic condensate thereof, and/or (C) at least one hydrolyzable organosilicon compound having the general formula (3): wherein R 11 , R 12 , Z 1 and Z 2 are as defined above, A is a divalent organic group having at least one fluorine atom, and a and b are as defined above, and/or a partial hydrolytic condensate thereof, and at least one vinyl polymer containing hydrolyzable silyl groups and/or hydroxysilyl groups.
