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 comprising electrically-conductive metal-containing particles dispersed in a binder system comprising a blend of a film-forming polymer and an anionic polymer. The combination of electrically-conductive metal-containing particles, film-forming polymer and anionic polymer provides a controlled degree of electrical conductivity and excellent adhesion to gelatin-containing layers, such as silver halide emulsion layers of photographic elements, in adhering contact with the electrically-conductive layer.
