Abstract
An aqueous latex coating composition comprising a non-conductive, water-insoluble copolymer of (1) methacrylic acid or maleic acid, (2) a styrene compound, and (3) a conjugated diene hydrocarbon or an alkyl ester of methacrylic acid or of acrylic acid is coated onto a sheet which is conductive or is non-conductive but may have a conductive layer adhered thereto. Thereby, sheets having a dielectric coating for electrographic printing are produced.
Claims6
An electrostatic sheet suitable for electrographic printing comprising a substrate in the form of a flexible or rigid sheet having adhered to at least one surface thereof a continuous dielectric film consisting essentially of a copolymer of from about 0.5 percent to about 8 percent of methacrylic acid of maleic acid and the balance consisting essentially of (a) a styrene compound and (b) a conjugated diene hydrocarbon or an alkyl ester of acrylic acid or of methacrylic acid;
- said alkyl ester having from 1 to 18 carbon atoms in the alkyl.
