Abstract: Method comprises (a) applying to a supporting surface for a viewing-screen structure of a cathode-ray tube a coating comprised of a dichromate-photosensitized organic binder, (b) exposing the coating of a pattern of actinic energy, including both heat energy and ultraviolet energy, (c) wetting the exposed coating with a dilute aqueous solution of an ammonium compound, such as ammonium oxalate, (d) and flushing the coating with an aqueous solvent to remove those portions of the coating that have been hardened solely by heat energy, while retaining portions of the coating that have been hardened by ultraviolet energy.
