Abstract
A conductive film-forming composition for use in the manufacture of electrostatic recording paper is provided. This composition comprises a copolymer of a diallylammonium halide derivative with a N-vinylacetamide derivative as an essential component. The conductive paper manufactured by coating or impregnating a substrate paper with this composition is of remarkably high practical value in terms of electrical conductivity, hardness, surface tackiness and solvent resistance.
