Method for multilayer coating with coating agents curable radiation.

Method for multilayer coating by applying one or more coats of filler and / or other layers of coating compositions on a substrate may already coated and subsequent application of a top coat consisting of a base structure / clearcoat varnish or a protective varnish monolayer pigment, wherein at least one of the layers of the multilayer structure is formed by coating agents at least partially curable by high-energy radiation, irradiating the layer (s) with UV radiation and IR radiation, characterized in that for the irradiation with UV and IR radiation a UV radiation source which has in its emission spectrum a strip of IR radiation and because alternately interleaving a UV filter and an IR filter and / or by sandwiching and alternatively removing the UV filter or used an IR past the radiation source filter are at least two intervals irradiaci n, while radiating with UV radiation interchangeably, IR radiation or with UV radiation simultaneously and IR radiation.
