Title: Electrolytically induced polymerization utilizing bisulfite adduct free radical precursor

Abstract: Polymerization of an ethylenically unsaturated compound is achieved by means of free radical initiators derived from the reaction of an aldehyde/bisulfite adduct with cupric ions resulting from electrolysis involving a copper anode. By including a photoconductive cathode in the system image-wise light exposure effects the formation of polymeric images in the polymerizable composition.
