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 monoethylenic derivative thereof. The coating is preferably pigmented with calcium carbonate, and the presence of the copolymerized acrylamide allows an increase in the pigment to binder ratio into the range of from 2:1 to 6:1.
