Abstract:
A curable composition for coatings which comprises: a component A consisting of a resin A-1 obtained by mixing an epoxy group-containing compound x component and a carboxyl group-containing compound y component and/or a resin A-2 based on an epoxy group-containing and carboxyl group-containing vinyl copolymer z component,a component B consisting of a vinyl copolymer whose main chain substantially consists of a vinyl copolymer chain and which has, within the molecule thereof, at least one hydrolyzable silyl group bound to a carbon atom as represented by the following general formula I: ##STR15##wherein R.sup.1 represents a hydrogen atom or an alkyl group containing 1 to 10 carbon atoms, R.sup.2 represents a hydrogen atom or a monovalent hydrocarbon group selected from among an alkyl group containing 1 to 10 carbon atoms, an aryl group containing 6 to 10 carbon atoms and an aralkyl group containing 7 to 10 carbon atoms and a represents an integer of 0 to 2, at one main chain terminus and/or on a side chain, anda component C consisting of a silicon compound represented by the following general formula VII:(R.sup.3 O).sub.4-b SiR.sup.4.sub.b VIIwherein R.sup.3 represents a hydrogen atom or an alkyl group containing 1 to 10 carbon atoms, an aryl group containing 6 to 10 carbon atoms or an aralkyl group containing 7 to 10 carbon atoms and the R.sup.3 groups may be the same or different, R.sup.4 represents an alkyl group containing 1 to 10 carbon atoms, an aryl group containing 6 to 10 carbon atoms or an aralkyl group containing 7 to 10 carbon atoms and when there is a plurality of R.sup.4 groups, they may be the same or different, and b represents an integer of 0 to 2 , and/or a partial hydrolyzate condensate thereof.
