Abstract
Abstract A thermosetting composition comprising (A) a carboxyl group-containing polyol resin, (B) a hydrolyzable silyl group-containing polymer, and at least one member selected from the group consisting of (C) a dehydrating agent and (D) an alcohol. The composition of the present invention is excellent in the physical properties of the film as well as the storage stability of the coating composition compared to the known compositions containing the curing catalyst.
