Abstract

Radiation-curable powder compositions, usable as paint or varnish, which comprise a mixture of at least one semi-crystalline polyester containing end methacryloyl groups and of at least one acrylic copolymer containing ethylenically unsaturated groups, these polyesters comprising the reaction products of a glycidyl methacrylate and of a semi-crystalline polyester containing end carboxyl groups.
