ABSTRACT:
A method for electrodeposition of an organic material on an electroconductive surface comprising placing the electroconductive surface to be coated in contact with an aqueous dispersion containing a water-insoluble, essentially electrically non-conductive, film-forming, organic polymer as cation-active particles wherein a substantial portion of the cation-activity is provided by sulfoxonium cations and passing an electric current from an electrode through the latex to the electroconductive surface in such a direction that the electroconductive surface is negatively charged, i.e., becomes a cathode in an electrophoretic cell. By use of alternating current both electrodes become coated with an adherent coating of polymer.
