  • Patent number: 4985473
    Abstract: Radiation curable coating compositions for providing solvent-resistant abhesive coatings comprise polyfluorinated acrylates and methacrylates, polyethylenically unsaturated crosslinking agents and a film-forming organic polymer. The compositions can be used after radiation curing to render substrates oil, soil, and water repellent. The cured compositions have particular use as release coatings in image transfer systems wherein a fused xerographic image is transferred from the release coated surface, to another surface due to the particular characteristics of the coatings. Novel poly(fluorooxyalkylene)urethane acrylate compounds are also disclosed.
