ABSTRACT:
This invention relates to 3,4-bis(halomethyl) benzophenone photoinitiators and these initiators admixed with unsaturated photopolymerizable compounds. When such compositions are irradiated by ultraviolet light, the benzophenone derivatives split off free radicals which initiate the photopolymerization of the unsaturated photopolymerizable compounds.
