Abstract

A novel polymeric co-initiator is disclosed 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.
