PROBLEM TO BE SOLVED: To provide a new kind of very effective polymeric co-initiator, easily producible and easily compatible with a wide range of radiation-curable compositions. SOLUTION: The invention relates to the new polymeric co-initiator comprising a dendritic polymer core with at least one co-initiating functional group as an end group. The polymeric co-initiators are useful in radiation-curable compositions such as varnishes, lacquers and printing inks and are especially useful in radiation-curable inkjet inks. The dendritic polymeric core is preferably a hyperbranched polymer. COPYRIGHT: (C)2006,JPO&NCIPI
