In accordance with one embodiment of the invention, a process for forming an electrically conductive layer is disclosed comprising (i) intercalating colloidal vanadium oxide with a water soluble vinyl-containing polymer, (ii) incorporating the intercalated colloidal vanadium oxide in a coating composition, and (iii) coating the coating composition on a substrate. In accordance with a second embodiment of the invention, a composition for forming an electrically conductive element or layer thereof is disclosed comprising (i) colloidal vanadium oxide intercalated with a water soluble vinyl-containing polymer and (ii) a binder which is distinct from the water soluble vinyl-containing polymer. Intercalation of vanadium oxide gels with water-soluble polymeric species in accordance with of the present invention results in a vanadium oxide gel having improved solution stability and reduced impact of solution aging on conductivity.

Colloidal vanadium oxide having improved stability

In accordance with one embodiment of the invention, an imaging element is disclosed comprising:(i) a support; (ii) at least one image forming layer; and (iii) an electrically-conductive layer comprising colloidal vanadium oxide intercalated with a water soluble vinyl-containing polymer. The electrically-conductive layer preferably additionally comprises a film-forming binder, which is distinct from the water soluble vinyl-containing polymer. The water soluble vinyl-containing polymer is preferably poly-N-vinylpyrrolidone, polyvinyl alcohol or an interpolymer thereof. Intercalation of vanadium oxide gels with water-soluble polymeric species in accordance with the present invention results in a vanadium oxide gel having improved solution stability and reduced impact of solution aging on conductivity, which improves manufacturing robustness and enables the use of many polymeric binders which could not be effectively used with conventional vanadium oxide gels in conductive layers of imaging elements.

Imaging element comprising an electrically-conductive layer containing

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.

The present invention is an imaging element including a support, at least one imaging layer, and an antistat layer. The antistatic layer includes an antistatic agent dispersed in a polyolefin binder.

Antistatic compositions for imaging elements

This invention relates to a motion picture print film having a support and having, in order, on one side thereof an antihalation undercoat and at least one silver halide emulsion layer and having, in order, on the opposite side thereof an antistatic layer, a protective overcoat; characterized in that said protective overcoat includes a polyurethane binder and the polyurethane binder has a tensile elongation to break of at least 50% and a Young's modulus measured at a 2% elongation of at least 50000 lb/in, and a topcoat farthest from the support which includes a hydrophilic binder at a weight percent of at least 20.

Motion picture print film

Catalysts for the conversion of synthesis gas to linear alcohols and aldehydes are disclosed. The catalysts are mixed oxides of copper, iron and either chromium or aluminum and wherein said mixed oxide has a delafossite type of crystal lattice structure.
