Abstract

A novel polymeric initiator is disclosed comprising a dendritic polymer core with at least one initiating functional group as an end group. The dendritic polymeric core is preferably a hyperbranched polymer. The polymeric initiators are useful in radiation curable compositions such as varnishes, lacquers and printing inks and are especially useful in radiation curable inkjet inks.
