ABSTRACT OF THE DISCLOSURE The present invention as disclosed provides a radiation curable coating composition comprising the addition reaction product of (i) a monoethylenically unsaturated adduct of a monoethylenically unsaturated carboxylic acid or a hydroxyalkyl ester thereof with an anhydride containing at least 3 carbon atoms and selected from monepoxides, lactones and mixtures thereof, said adduct containing an average of at least 1 mole of anhydride per mole of hydroxyester and an average of at least 2 moles of anhydride per mole of acid moiety, with (ii) an organic compound containing a plurality of groups capable of reacting with active hydrogen. The organic compound (ii) includes those (such as polyisocyanates) which form a urethane linkage, those (such as polycarboxylic polyanhydrides) which form an ester linkage, or those (such as polyexpoxides) which form an ether linkage.
