Abstract
The present invention provides a process for imparting a simulated patina, or antique appearance to a substrate by using a coating composition comprising a perlite based effect pigment. The perlite based effect pigment functions as colorant and matting agent and shows an almost angle independent brightness. The process provides, for example, decorative wall coatings showing enhanced antique, or patina effects as compared to conventional effect pigments on basis of mica.
