A process for the production of a coating layer on a three-dimensional shaped substrate, comprising the steps: (1) providing a three-dimensional shaped substrate, (2) initial application of a coating layer on the surface of the substrate from a coating composition curable by free-radical polymerization of olefinic double bonds on UV irradiation and (3) irradiating the coated substrate with UV radiation; wherein the coating composition contains the following constituents: A) at least one free-radically polymerizable binder containing olefinically unsaturated groups, B) optionally, at least one free-radically polymerizable monomeric reactive diluent containing one or more olefinically unsaturated groups, C) at least one photoinitiator for free-radical polymerization, and D) at least one metal compound.
