Abstract

Imaging element, such as photographic electrostatographic thermal imaging elements are comprised of a support, an imaging-forming layer, and a transparent electrically-conductive layer which includes an effective amount of polypyrrole/poly(styrene sulfonic acid). In a preferred embodiment, the polypyrrole/poly(styrene sulfonic acid) is dispersed in a binder.

Claims

1. An imaging element for use in an image-forming process;

said imaging element comprising a support, an image-forming layer; and

a transparent electrically-conductive layer comprising polypyrrole/poly(styrene sulfonic acid).

2. The imaging element according to claim 1, wherein the polypyrrole/poly(styrene sulfonic acid) is dispersed in a film-forming binder.

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

4. The imaging element according to claim 1, wherein the polypyrrole/poly(styrene sulfonic acid) includes substituted pyrrole.

5. A transparent coating composition for use in an imaging element comprising:

polypyrrole/poly(styrene sulfonic acid) dispersed in a film-forming binder.

6. The transparent coating composition according to claim 5, wherein the film-forming binder is gelatin.

7. The transparent coating composition according to claim 5, wherein the poly-pyrrole/poly(styrene sulfonic acid) includes substituted pyrrole.
