THE INVENTION RELATES TO ACID-HARDENING RESIN COMPOSITIONS HAVING INCORPORATED THEREIN A BENZOPHENONE COMPOUND EACH OF THE TWO BENZENE NUCLEI OF WHICH BEING SUBSTITUTED BY A HALOGENATED METHYL GROUP. IF SAID COMPOSITIONS ARE IRRADIATED BY UV-LIGHT SAID BENZOPHENONE COMPOUND SPLITS OFF HYDROGEN HALIDE WHICH, IN TURN, CATALYSES THE HARDENING OF THE RESIN COMPOSITION.
