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.

Polymeric initiators

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.

Photoreactive polymers

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.
