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.
