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.
