摘要

The invention relates to radiation curable compositions comprising at least one radiation curable (meth)acrylic copolymer A prepared by reacting a copolymer P obtained from copolymerizing monomers comprising (i) from 10 to 50 mole% of at least one (meth)acrylate (a1) comprising a first functional group, and (ii) from 50 to 90 mole% of at least one alkyl(meth)acrylate (a2) having at least 6 carbon atoms in the alkyl chain, with at least one (meth)acrylate (a3) comprising a second functional group which can react with the first functional group of (meth)acrylate (a1), said radiation curable (meth)acrylic copolymer A having a number average molecular weight Mn of 1000 to 23000, and their use for making inks.
