Abstract

Radiation curable compositions with a polymeric co-initiator are disclosed comprising a dendritic polymer core with at least one co-initiating functional group as an end group. The dendritic polymeric core is preferably a hyperbranched polymer. Industrial applications include varnishes, lacquers and printing inks. The polymeric co-initiator is especially useful in radiation curable inkjet ink.
