Abstract
The present invention has its objects to provide a curable composition for coatings which can provide coatings or paint films excellent in acid resistance, scratch resistance, stain resistance and heat curability, with very good weather resistance and appearance; and coated articles and a resin composition obtained from the curable composition. The curable composition comprises: (A) 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; (B) 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 general formula (I): ##STR1## and (C) a silicon compound represented by the general formula (VII): EQU (R.sup.3 O).sub.4-b SiR.sup.4.sub.b (VII) and/or a partial hydrozylate condensate thereof.
