Abstract: The invention relates to a binder polymer obtainable by copolymerizing a monomer mixture comprising a vinyl monomer M1 and a butenolide monomer M2, wherein the vinyl monomer M1 is a vinyl ether, a vinyl ester, or a combination thereof, and the butenolide monomer M2 is a 5-alkoxy-2(5H)-furanone. The invention further relates to a coating composition comprising such binder polymer and to a substrate coated with a coating deposited from such coating composition.

Abstract: A radiation-curable coating composition is provided comprising a 5-hydroxy or 5-alkoxy-2 (5H)-furanone compound A, and a compound B with two or more vinyl ether or vinyl ester groups, wherein the molar ratio of vinyl moieties in compound B and furanone moieties in compound A is at least 0.5, and wherein the coating composition is free of a compound with two or more acryloyl or methacryloyl groups. Also provided are a method of coating a substrate comprising applying such coating composition to a substrate and radiation-curing the coating composition to form a cured coating, and a coated substrate obtainable by such method.
