Abstract
The invention relates to a process for applying coating films to three-dimensionally curved substrates, and to a process for producing coating films. In order to apply the coating film, which has at least a coating layer and an adhesive layer, the radiation-curable coating layer of the coating film is partially cured so as to be free from tack before being applied to the substrate. Following application, the coating film is subjected to electromagnetic radiation at below the wavelength of the visible spectrum and is fully cured. To produce a coating film, the coating layer is partially cured so as to be free from tack and in this state is stored until it is applied to a substrate. The coating layer can be attached at least indirectly to a smooth support base in conjunction with an adhesive layer. The coating layer and/or the coating film can be detached from a roller in applying the coating film to a substrate.
