The present invention relates to a radiation curable coating composition comprising (A) a compound according to P-(D-(meth)acrylate)<SUB>n </SUB>having a number average molecular weight (Mn) of at least 500 kg/kmol, wherein n=240, P=oligomeric or polymeric backbone, and D comprises an urethane group and an heterocyclic group, said heterocyclic group having a Boltzmann average dipole moment of at least 2.5 Debye, and (B) a reactive diluent. The heteorocylic group is preferably an oxazolidone group. The invention further relates to a method for making a resin composition comprising a compound comprising an oxazolidone group and an (meth)acrylate group, said method comprising a reaction step introducing the (meth)acrylate group into the compound, wherein said reaction step is carried out in the presence of an antioxidant.
