IM-0250-A TITLE ELECTROGRAPHIC RECORDING ELEMENT WITH REDUCED HUMIDITY SENSITIVITY Abstract of the Disclosure Electrographic recording element with reduced humidity sensitivity comprising (1) a base, e.g., paper, polymer film, (2) a conductive layer of a continuous coating of an electroconductive composition comprising (a) polymeric binder, (b) electroconductive powder comprising amorphous silica or a silica-containing material in association with a two- dimensional network of antimony- containing tin oxide crystallites in which the antimony content ranges from 1 to about 30% by weight of tin oxide; and (3) a dielectric layer. Mixtures of two or more different sized electrocon- ductive powder particles can be used. The electrographic recording element is useful for recording high-speed computer output, e.g., in geophysical mapping, weather map printing, architectural and engineering drawings, etc.
