Abstract

A heatsealable electrostatic recording sheet is provided which includes an electrically conductive substrate, a dielectric coating on one surface and a heatsealable coating on the other side. The dielectric coating is composed of an electric-charge-retentive layer of an insulating or dielectric polymer film. The film also contains dispersed therein, pigment particles and preferably an antiblocking agent selected from the groupe consisting of dielectric alkaline earth metal salts of fatty acids, alkali metal salts of fatty acids, waxes, and mixtures thereof and in particular calcium stearate. The heatsealable coating is composed of a thermoplastic film-forming polymeric material which contains an electrically conductive additive, such as a polymeric quaternary ammonium halide, and in particular, polydialkyl diallyl ammonium halide.
