PROCESS FOR THE PREPARATION OF RADIATION CURABLE COMPOSITIONS

摘要

The present invention relates to a process for the preparation of radiation curable compositions comprising at least one radiation curable (meth)acrylic copolymer A and at least one (meth)acrylated epoxy compound B, said process comprising: - the preparation of a copolymer P by copolymerization of monomers comprising : (i) from 0.1 to 50 mole% of at least one epoxy (meth)acrylate (a1), and (ii) from 50 to 99.9 mole% of at least one other copolymerizable monomer (m) different from (a1) in the presence of at least one non-copolymerizable epoxy compound (b1) and - further reacting copolymer P thereby obtained and the non-copolymerizable epoxy compound (b1) with at least one carboxylic (meth)acrylate (a3).
