Abstract

A method of optically printing conductive characters using charge transfer compounds is provided. The method is characterized by depositing an organic .pi. electron donor compound dissolved in a halogenated hydrocarbon (halocarbon) on a suitable substrate and selectively exposing the so coated substrate to actinic radiation to obtain a permanent, highly conductive, image.
