Abstract
Abstract The invention relates to photopolymerizable polymeric compositions useful as coating and moldable compositions which are hardenable by ultraviolet radiation. These coating and moldable compositions comprise mixtures of photopolymerizable or photocrosslinkable unsaturated compounds and at least one photoinitiator selected from the group consisting of halogenated heterocyclic compounds having at least one diazole or triazole group and at least one benzyl halide group.
