Abstract

A powder paint containing at least one hydroxyl group-containing binder and at least one cross-linking agent with free isocyanate groups dispersed in the binder in the form of discrete particles with diameters of between 0.1 and 150 micrometres, in which the binder is A1) at least one hydroxyl group-containing acrylate copolymer with a glass transition temperature of 30 to 80 °C, a number average molecular weight of 2,000 to 15,000 daltons and an OH number of 60 to 180 mg KOH/g, where the hydroxyl groups of the acrylate copolymer consists of primarily bonded OH groups to the extent of over 50%, and/or A2) the reaction product of a carboxyl group-containing acrylates copolymer and an epoxide group-containing compound or the reaction product of an epoxide group-containing acrylate copolymer and a carboxyl group-containing compound, where the carboxy/epoxy reaction may take place before or during the reaction of the binder with the cross-linking agent
