  • Photocurable coating compositions
    Patent number: 5002975
    Abstract: Liquid, photocurable coating compositions containing nitrile copolymers. Such compositions comprises from about 10 percent to about 60 percent by weight of a high nitrile copolymer, containing at least about 70 percent by weight of a nitrile polymer; from about 30 percent to 90 percent by weight of a photopolymerizable solvent for the high nitrile copolymer, wherein the photopolymerizable solvent is selected from the group consisting of N-vinyl pyrrolidone, cyanoethylacrylate, styrene, N,N-dimethylacylamide, N,N-methylenebisacrylamide, gamma-butyrolactone and combinations thereof, and from about 0.1 percent to about 10 percent by weight of a photoinitiator soluble in the photopolymerizable solvent for curing the high nitrile copolymer with the incorporation of at least 50 percent by weight of the solvent therein upon exposure to ultraviolet radiation, having a wavelength of from about 2000 .ANG. to 14,000 .ANG.
