Multilayer coating having a clear top coat formed on a color base coat and method of forming the same

摘要

A clear top coat composition comprising a film-forming acrylic polymer having a plurality of cross-linkable functional groups, a volatile organic liquid diluent capable of carring the film-forming polymer, a cross-linking agent for the film-forming polymer, and internally cross-linked polymer microgel particles stably dispersed in the mixture of the film-forming polymer, the diluent and the cross-linking agent. The composition is applied wet-on-wet a metallic color base coat having a similar composition containing the microgel particles and a metallic flake pigment, and cured simultaneously with the base coat.
