US 5,853,819 A · Imaging element comprising an electrically conductive layer formed by a glow discharge process

Abstract

Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer produced by coating a layer comprised of a metallo-organic compound and a film-forming binder and subjecting such layer to glow discharge treatment to render it electrically conductive. Use of a metallo-organic compound in combination with a glow discharge treatment provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

Dependent claims

A method for the manufacture of an electrically-conductive material that is useful as a base for a photographic element;

said method comprising the steps of:
(1) providing a polymeric support;
(2) forming a coating composition comprising a metallo-organic compound and a film-forming binder;
(3) coating a non-conductive layer of said coating composition on the surface of said support;
and
(4) subjecting said non-conductive layer to glow discharge treatment in an oxygen containing atmosphere for a period of time of from 0.3 seconds to 15 seconds wherein the metallo-organic compound is decomposed and the layer is rendered electrically-conductive.
