ABSTRACT:
A liquid ethylenically unsaturated polyetherurethane composition having a viscosity at 24.degree. C. of 1000 to 10,000 centipoises dispersible in dilute aqueous sodium hydroxide is capable of being polymerized by actinic light to yield a solid having a Shore A hardness of at least 30 when the composition contains 0.5 to 15 percent dialkyl, aminoalkyl, acrylate or methacrylate. The resulting polymer is capable of taking on excellent halftone or half dot quality.
