Electrographic coating containing aqueous emulsion copolymerized acrylamide copolymers.

摘要

Electrically conductive paper is coated with an insulating coating which is an aqueous latex of an aqueous emulsion copolymer of monethylenically unsaturated monomers comprising from 5% to 40% of copolymerized acrylamide or a monoethylenic derivative thereof, preferably isobutoxymethyl acrylamide. A proportion of monoethylenically unsaturated carboxylic acid is preferably included in the copolymer.
