POWDER COMPOSITIONS WITH SEMICRYSTALLINE POLYESTER AND ACRYLIC COPOLYMER BASE CONTAINING ETHYLENICALLY UNSATURATE GROUPS

摘要

The invention concerns powder compositions hardenable by radiation usable as paint or varnish comprising a mixture of at least a semicrystalline polyester containing terminal methacryloyl groups and of at least an acrylic copolymer containing ethylenically unsaturate groups, these polyesters comprising the reaction products of a glycidyl methacrylate and of a semicrystalline polyester containing terminal carboxyl groups.
