Abstract

An imaging element such as a photographic, electrostatic, or thermal imaging element is comprised of a support, an image-forming layer, and a transparent electrically conductive layer which includes an effective amount of poly(3,4-ethylene dioxypyrrole/styrene sulfonate). In a preferred embodiment, the poly(3,4-ethylene dioxypyrrole/styrene sulfonate) is dispersed in a polymeric binder.

Claims

a support,

at least one image-forming layer superposed on said support;

a transparent electrically conductive layer superposed on said support comprising a dispersion of poly(3,4-ethylene dioxypyrrole/styrene sulfonate) in a film-forming binder.

2. The imaging element according to claim 1, wherein the film-forming binder comprises gelatin.

3. The imaging element according to claim 1, wherein the film-forming binder comprises a vinylidene chloride-based terpolymer latex.

4. The imaging element according to claim 1, wherein the support is selected from the group consisting of cellulose nitrate film, cellulose acetate film, poly(ethylene terephthalate) film, poly(ethylene naphthalate) film, polystyrene film, polycarbonate film, glass metal, paper and polymer-coated paper.

5. An imaging element comprising

a support,

at least one image-forming layer superposed on said support;
