ABSTRACT:
A radiation curable powder coating composition that contains a) a binder having at least one amorphous urethane acrylate having a glass transition temperature of at least 35° C. and a melting point of from 50 to 120° C.; and b) an auxiliary, can be crosslinked by radiation to produce a lightfast and weather-stable film.
