Electrostatic recording element

Abstract

An electrostatic recording element which is capable of forming clear images thereon independently from the temperature and humidity of the ambient atmosphere, and of being stored for a long period of time without deterioration thereof, which comprises: (a) a substrate comprising paper or a synthetic polymer film; (b) a conductive layer located on a surface of said substrate and comprising (1) powdered electroconductive zinc oxide which has been doped with a member selected from the group consisting of aluminium, copper and tin, and which has a specific resistivity of from 1.times.10.sup.-1 to 1.times.10.sup.2 ohm-cm, under a pressure of 150 kg/m.sup.2, (2) an organic fluorescent brightening agent in an amount of from 0.1 to 2.0%, based on the weight of said electroconductive zinc oxide, and (3) a binding material uniformly mixed with the electroconductive zinc oxide and the organic fluorescent brightening agent; and (c) a dielectric layer located on the conductive layer and having an electrostatic recording surface.
