<p>Disclosed is a conductive coating composition comprising a diquaternary ammonium compound of the formula wherein R1 is an alkyl group or alkylene group having from about 12 to about 22 carbon atoms, R2, R3, R4, R5, and R6 are independently selected from the group consisting of alkyl groups and aryl groups having from 1 to about 8 carbon atoms, n is a number of from 1 to about 5, and A is an anion. Also disclosed is an electrographic paper which comprises a base sheet coated on one surface with a dielectric coating composition and on its opposite surface with a conductive composition comprising a diquaternary ammonium compound of the formula shown. In addition, an electrographic imaging process is disclosed which comprises (a) providing an electrographic paper comprising a base sheet coated on one surface with a dielectric coating composition and on its opposite surface with a conductive coating which comprises a diquaternary ammonium compound of the formula shown; (b) generating an electrostatic latent image on the paper with an electrographic writing means; and (c) developing the latent image.</p> |
