Process for multi-layer special effect coating

Abstract

The invention relates to a process for multi-layer special effect coating of substrates comprising the following steps: A) applying a colour-imparting solid-colour base coat layer of a conventional colour-imparting solid-colour base coat I containing conventional colour-imparting absorption pigments onto a substrate precoated with a filler and/or primer coating composition and optionally, further coating compositions, B) applying a special effect base coat layer of a metallic base coat II, which contains aluminum pigments in flake form with an average particle thickness of 0.01 to 0.10 μm and an average particle size of 5-50 μm, onto the base coat layer applied in step A) in a film thickness which is reduced relative to the film thickness produced in step A), C) optionally intermediately drying the coating so applied, D) applying a clear coat layer of a transparent clear coat and E) curing the thus obtained coating.
