<p>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 1x10-1 to 1x102 ohm-cm, under a pressure of 150 kg/m2, (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.</p> |
