The invention relates in general to the art of polymer deposition on metallic surfaces, and in particular to the art of image-wise deposition of polymer on metallic surfaces. The general object of this invention is to provide a method of photoelectrolytic initiated polymerization in which the monomer is not in direct contact with the electrically conductive substrate until the actual moment of polymerization so that autopolymerization or deterioriation of the monomer is avoided. The polymer is formed on a metal surface such as a stainless steel plate by first making the plate the cathode of a light responsive electrolytic cell. A potential is then applied across the electrodes of the cell causing image-wise passage of current therethrough. Polymer is then deposited in an image-wise fashion by immersing the plate in an acid-peroxide-monomer solution.
