Abstract

Process for producing a multi-layer lacquer finish, in which a surfacer coating compound is applied to a substrate optionally pre-coated with a priming layer and/or further coating layers, and a top coating comprising a colour-imparting and/or special-effect-imparting base lacquer layer and a transparent clear lacquer layer, or a top coating comprising a pigmented one-layer top lacquer, is then applied, in which coating compounds which contain binders which are curable by free radical and/or cationic polymerisation are employed as the surfacer, the base lacquer and the clear lacquer as well as the one-layer top lacquer, and wherein the said binders are cured by means of high-energy radiation.
