Abstract
The present invention is an imaging element which includes a support, at least one image forming layer superposed on the support, a transparent magnetic recording layer, and at least one electrically-conductive layer. The electrically-conductive layer includes crystalline, electronically-conductive acicular metal-containing particles dispersed in a sulfonated polyurethane film-forming binder. The transparent magnetic recording layer is composed of magnetic particles dispersed in a second film-forming binder and is superposed on the electrically-conductive layer.

A multilayer imaging element comprising:
- a support;
- at least one image-forming layer superposed on the support;
- at least one transparent electrically-conductive layer superposed on the support comprising electronically-conductive acicular metal-containing particles dispersed in a sulfonated polyurethane film-forming binder;
- and
- a transparent magnetic recording layer comprising magnetic particles dispersed in a film-forming binder.
A photographic film comprising:
- a support;
- a silver halide emulsion layer superposed on a first side of said support;
- an electrically-conductive layer superposed on a second side of said support, wherein said electrically-conductive layer comprises electronically-conductive acicular metal-containing particles dispersed in a sulfonated polyurethane film-forming binder;
- and
- a transparent magnetic recording layer overlying said electrically-conductive layer comprising magnetic particles dispersed in a film-forming binder.
A thermally-processable imaging element comprising:
- a support;
- an imaging layer superposed on a first side of said support;
- an electrically-conductive layer superposed on a second side of said support, wherein said electrically-conductive layer comprises electronically-conductive acicular metal-containing particles dispersed in a sulfonated polyurethane film-forming binder;
- and
- a transparent magnetic recording layer overlying said electrically-conductive layer comprising magnetic particles dispersed in a film-forming binder.
