Abstract: A liquid ethylenically unsaturated polurethane composition having no free NCO and a viscosity of 2,000 to 10,000 centipoises at 24.degree. C. dispersible in dilute caustic and capable of being polymerized by actinic light to yield a solid having a Shore A hardness of at least 30. Said composition may contain a diluent and a photosensitizing agent to adjust the viscosity and making the composition more readily utilizable for making printing plates.
