Abstract
An improved electroconductive resin composition is obtained by using a water-dispersible, film-forming acrylamide polymer as a binder and extender for a water-soluble quaternary ammonium electroconductive resin. Particularly useful is a self-binding blend of about 65-95 wt. % polyvinylbenzyltrimethylammonium chloride and about 5-35 wt. % nonhydrolyzed polyacrylamide which can be formulated as an aqueous dispersion with clay or other printing pigments. Applied to a nonmetallic substrate, such as paper or an organic polymer film, the improved electroconductive resin composition reduces the surface electrical resistivity of the substrate and also provides improved holdout to aromatic and aliphatic solvents.
