ELECTROGRAPHIC COATINGS CONTAINING ACRYLAMIDE COPOLYMERS ABSTRACT Electrically conductive paper is coated with an insulating coating to provide improved electrographic properties using a solvent-soluble copolymer comprising from 5% to 40% of copolymerized acrylamide or a mono- ethylenic derivative thereof. The coating is prefer- ably pigmented with calcium carbonate, and the presence of the copolymerized acrylamide allows an increase in the pigment to binder ration into the range of from 2:1 to 6:1.
