Abstract:

This invention is directed to electroconductive paper and to the processes for preparing same which comprises a substrate containing an effective amount of an electroconductive water soluble, quaternary ammonium polymer. The polymer is prepared by reacting substantially stoichiometric amounts of at least one aromatic ditertiary amine and one or more anion-containing organic compound. The polymer is applied to the substrate, e. g. paper by conventional methods to obtain a coated surface characterized as having a resistivity of less than about 10. sup. 11 ohms per square centimeter at relative humidities ranging from about 10% to 90%.
