Abstract:
An organic solvent-based heat-curable high solid coating composition comprising:(A) a carboxyl-containing compound having an acid value of 50 to 500 mg KOH/g, wherein 20 mol % or more of the carboxyl groups are silylated carboxyl groups represented by the formula ##STR21## wherein R.sup.1 and R.sup.2 are the same or different and each represent a C.sub.1-18 alkyl group, a C.sub.1-6 alkoxyl group, a phenyl group, an aryl group, a trimethylsiloxy group, a hydrogen atom, a chlorine atom or a fluorine atom; and R.sup.3 is a C.sub.1-18 alkyl group, a phenyl group, an aryl group or a trimethylsiloxy group;(B) at least one epoxide selected from (B-1) an epoxy-, hydroxyl- and hydrolyzable alkoxysilyl-containing vinyl polymer, (B-2) the vinyl polymer (B-1) wherein 20 mol % or more of the hydroxyl groups are silylated hydroxyl groups represented by the formula ##STR22## wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above, and (B-3) an epoxy compound having a number average molecular weight less than 1,000; and(C) a crosslinked particulate polymer;the composition having a solid content of 65 wt. % or more.
