Abstract

A process for the production of a multi-layer coating includes applying a coating layer from an aqueous pigmented coating composition A onto a substrate provided with an EDC primer and applying a base coat layer from an aqueous coating composition B overlying the coating layer. A clear coat layer is applied onto the base coat layer and the three coating layers are jointly bake-cured. The coating compositions A and B are different from each other and coating composition A comprises (i) binder solids, (ii) free polyisocyanate, (iii) a pigment content free of special effect pigments and comprising carbon black pigment and/or titanium dioxide pigment, and (iv) talcum filler.
