Electrolytically induced polymerization utilizing bisulfite adduct free radical precursor

摘要

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.
