ABSTRACT:
An electrostatic recording sheet is produced by coating the opposite surfaces of a paper sheet with an electroconductive coating composition including a cationic polymer electroconductive agent and a cationic sizing agent to form electroconductive layers and further coating one of said electroconductive layers with a dielectric coating composition in the form of an aqueous polymer dispersion to form a recording layer via a penetration resist layer. The penetration resist layer is formed of a gelated material produced by an ionic reaction on contact of said aqueous polymer dispersion with said electroconductive layer.
