ABSTRACT:
A method for producing an electrode pattern in a conductive polymeric layer comprising the steps of: (a) contacting a charge pattern with an electrographic developer composition comprising a carrier and marking particles having a polarity opposite that of said charge pattern thereby producing a developed image pattern, wherein said marking particles contain a conductivity modifier or a precursor thereof; (b) applying the developed image pattern to a conductive layer containing a conductive polymer on a substrate and (c) transferring said image pattern onto a said conductive layer. An element formed by the method is also disclosed.
