Abstract
Disclosed are a coating composition comprising a polymer dispersed in an aqueous medium, the polymer containing (a) a hydrolysate of an organosilane and/or a condensation product thereof and (b) a vinyl polymer containing a silyl group having a silicon atom bound to a hydrolytic group and/or a hydroxyl group, and further comprising (c) an oxazoline derivative as a crosslinking agent and a hardened film obtained therefrom. The above coating composition completes the hardening reaction of a coating film at low temperature for a short period of time, high in hardness immediately after hardening, and having water resistance, weather resistance, organic chemical resistance, acid resistance, alkali resistance, wear resistance and durable adhesion.
