Abstract

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.
