Abstract

A novel photoreactive polymer is disclosed comprising a dendritic polymer core with at least one initiating functional group and at least one co-initiating functional group. The photoreactive polymers are useful in radiation curable compositions are varnishes, lacquers, printing inks and radiation curable ink-jet inks. The dendritic polymeric core is preferably a hyperbranched polymer.
