Imaging element comprising an improved electrically conductive layer containing acicular
metalcontaining particles |
(57) 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 µm 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 µm 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.
