Abstract

A process for producing a repair coating This invention relates to a process for producing a multi-layer repair coating by the application of a transparent clear lacquer coat, which is unpigmented or which contains colourless pigment, to a predried or hardened colour- and/or effect-imparting base pigment coat, or by the application of a pigmented covering lacquer coat to an optionally precoated substrate. Binder vehicles which are hardenable exclusively by radical polymerisation are used for the production of the transparent clear lacquer coat or of the pigmented covering lacquer coat, and hardening is effected by means of pulsed, high-energy UV radiation.
