Abstract
A process for generating electrically conductive patterns on a dielectric substrate, such as an insulating sheet, which comprises applying to preselected areas of the substrate a preselected concentration of an ink in the form of an oxidizing agent, such as a solution of a ferric salt, e.g., ferric chloride or ferric ethylbenzenesulfonate, and which can also contain a suitable binder or thickening agent, to form printed images on the substrate surface. The resulting printed surface of the substrate is then exposed to an excess of reactant, e.g., pyrrole monomer in vapor phase, which reacts with the oxidizing agent to develop conductive images, as by forming polypyrrole, in those printed areas of the substrate containing the oxidizing agent.
