A process for the production of a coating layer from a coating composition curable with high-energy radiation on a substrate, comprising the successive steps:

• a) providing a substrate to be coated,
• b) applying a backing foil coated on one side with an uncured or at least only partially cured coating layer of a coating composition curable by means of high-energy radiation, with its coated side on the entire surface or at least one sub-zone of the surface of the substrate,
• c) irradiating the entire coating applied in step b) with high-energy radiation, and
• d) removing the backing foil from the coating which remains on the substrate;
• wherein irradiation of the coating proceeds through the backing foil and/or after removal of the backing foil.
