Abstract

A method of coating an article is described. The method comprises the steps of (A) coating at least one layer on an article with a coating composition comprising a cross-linkable polymer and a cross-linking agent, said composition being substantially free of strong acid, (B) coating a clearcoat layer above the layer from step A) with a coating composition comprising 1) a polymer comprising a hydroxy functional group, and 2) a blocked isocyanate cross-linking agent, and (C) curing the coated article.
This method allows the preparation of a basecoat-clearcoat coating utilizing a one-component clearcoat that has the environmental etch resistance provided by blocked isocyanate cross-linking agents, but with reduced yellowing.
