Abstract (en)
[origin: EP0947878A2] The present invention is an imaging element which includes a support, an image-forming layer superposed on the support and an electrically-conductive layer superposed on the support. The electrically-conductive layer contains a film-forming binder and acicular, crystalline single-phase, electrically-conductive metal-containing particles. The acicular, crystalline single-phase, conductive metal-containing particles have a diameter less than or equal to 0.02 mu m and an aspect greater than or equal to 3:1. The electrically-conductive layer is formed by dispersing the acicular particles using polymeric milling media having a size less than 350 mu m to form a colloidal dispersion, combining the colloidal dispersion with the film forming binder to form a mixture, coating the mixture onto the support and drying the mixture to form the electrically-conductive layer.
