Abstract

A flexible, aminoplast-curable film-forming composition and a process for preparing multi-layered coated articles coated with a pigmented or colored base coat and a transparent or clear topcoat are disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a transparent topcoat to the base coat. The transparent topcoat composition is a flexible, curable film-forming composition comprising (1) a polyether polymer containing a plurality ofterminal or pendant carbamate groups of structure (1); and (2) an aminoplast cross-linking agent. The topcoat composition provides a flexible composite coating with improved acid etch resistance, making the composite coating particuarly useful as a topcoat for plastic automotive parts.
