ABSTRACT:
In accordance with one embodiment of the invention, an imaging element is disclosed comprising: (i) a support; (ii) at least one image forming layer; (iii) a transparent magnetic recording layer comprising magnetic particles dispersed in a first film-forming binder; and (iv) an electrically-conductive layer comprising colloidal vanadium oxide intercalated with a water soluble vinyl-containing polymer dispersed in a second film-forming binder. The water soluble vinyl-containing polymer is preferably poly-N-vinylpyrrolidone, polyvinyl alcohol or an interpolymer thereof. Intercalation of colloidal vanadium oxide with water soluble vinyl-containing polymers results in improved stability of coating formulations, and an improved colloidal vanadium oxide which is compatible with a wider selection of polymeric binders and facilitates higher binder:vanadium oxide ratios which can improve adhesion of a transparent magnetic layer.
