Chip-resistant composite coating

摘要

A coated article is described comprising a substrate having thereon a color-plus-clear composite coating wherein (a) the color layer of the composite coating is derived from a coating composition comprising: (1) a polymer component having active hydrogen-containing groups thereon, (2) an aminoplast curing agent, (3) an acid cure catalyst, and (4) an amine selected from the group consisting of substituted or unsubstituted pyridine or a substituted or unsubstituted N-alkyl primary amine, and (b) the clear layer of the composite coating is derived from a curable coating composition comprising an epoxy-functional component and an acid-functional or anhydride-functional component.
