ABSTRACT:
The present invention is a multilayer imaging element which includes a support, one or more image-forming layers superposed on the support, and an outermost transparent electrically-conductive, non-charging, overcoat layer superposed on the support. The over coat layer is colloidal, acicular electrically-conductive metal-containing particles, dispersed in a film-forming binder at a volume percentage of acicular conductive metal-containing particles of from 2 to 60. The overcoat layer further includes a first charge control agent which imparts positive charging properties and a second charge control agent which imparts negative charging properties.
