ABSTRACT:
A radiation-polymerizable mixture comprising a polymeric binder, a radiation-activatable polymerization initiator and a polymerizable acrylate or methacrylate ester having at least two urethane groups in the molecule, said ester being a reaction product of glycerol dimethacrylate or glycerol diacrylate and a polyisocyanate obtained by reacting a polyhydroxy compound having from two to six hydroxyl groups with a diisocyanate or a reaction product of glycerol dimethacrylate or glycerol diacrylate and a diisocyanate. The new polymerizable urethanes provide the mixture with a high light-sensitivity, good reciprocity and a low tendency to crystallize.
