  • Polymeric initiators
    Patent number: 7875698
    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.
    Type: Grant
    Filed: June 28, 2005
    Date of Patent: January 25, 2011
    Assignee: Agfa Graphics NV
    Inventors: Luc Vanmaele, Johan Loccufoer, Yu Chen, Holger Frey
  • Photoreactive polymers
    Patent number: 7538144
    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.

  • Polymeric co-initiators
    Patent number: 7507785
    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.
