Process for the production of paint coating layers

Production of coating layer on substrate involves: applying backing foil (F1) with its coated side on at least one sub-zone of substrate; irradiating entire coating with high-energy radiation; and removing (F1) from coating which remains on substrate. (F1) Is coated on one side with uncured or at least partially cured coating layer of coating composition curable by high-energy radiation. The irradiation of coating proceeds through (F1) and/or after removal of (F1). Production of a coating layer from a composition (C1) curable with high-energy radiation on a substrate involves: (1) applying a backing foil (F1) coated on one side with an uncured or at least partially cured coating layer of (C1), with its coated side on the entire or at least one sub-zone of surface of the substrate; (2) irradiating the entire coating with high-energy radiation; and (3) removing (F1) from coating which remains on the substrate. The irradiation of the coating proceeds through (F1) and/or after removal of (F1). 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; €ƒ€ƒ€ƒ wherein irradiation of the coating proceeds through the backing foil and/or after removal of the backing foil.
