Process for the production of multi-layer lacquer coatings on

A method of producing a multi-layer coating comprising the application of a color- and/or effect-imparting base lacquer coat of an aqueous base lacquer, the wet-into-wet-application on to the aqueous base lacquer coat of a clear lacquer coat of a two-component polyurethane clear lacquer, which is produced shortly before the application thereof by mixing a master lacquer component, which contains hydroxy-functional binder vehicles and solvents, with a polyisocyanate component, and joint stoving of the aqueous base lacquer and clear lacquer coats, wherein the two-component polyurethane clear lacquer which is used contains 0.01 to 1% by weight, with respect to the clear lacquer solids, of one or more additives with a surface tension-lowering effect, wherein at least 25% by weight of the additives with a surface tension-lowering effect is contained in the polyisocyanate hardener component before mixing.
