Abstract
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 comprised of a vanadium pentoxide colloidal gel, a polyesterionomer binder and a methoxyalkylmelamine. The electrically-conductive layer exhibits electrical conductivity which is both process-surviving and essentially independent of humidity.
