Beschreibung
Zusammenfassung:	An uncured branched polyester-urethane resin prepared by free radical polymerization of an unsaturated polyester prepolymer having a polyol segment, an unsaturated polycarboxylic acid and/or an anhydride and/or ester thereof, and a urethane segment, wherein the polymerization occurs primarily by reaction of the unsaturation is disclosed. Coatings comprising the same are also disclosed, as are substrates coated at least in part with such coatings. La présente invention concerne une résine polyester-uréthane ramifiée non durcie, préparée par polymérisation radicalaire d'un prépolymère de polyester insaturé ayant un segment polyol, un acide polycarboxylique insaturé et/ou un anhydride et/ou un ester de celui-ci, et un segment uréthane, la polymérisation survenant principalement par réaction de l'insaturation. L'invention concerne également des revêtements comprenant ladite résine, ainsi que des substrats enduits au moins partiellement de ces revêtements.
