Abstract
Abstract Electroconductive cationic resins prepared by the reaction of a 1,4-dihaloalkene-2 compound and a di(tertiary amine). The resins are quaternary ammonium compounds. They may be prepared in aqueous medium. They may be blended with polyvinyl alcohol and the blends may be used to provide solvent resistant electroconductive coatings to sheet materials used in electrographic printing.
