Disclosed is an electrostatic recording medium comprising an electroconductive support and as formed thereon a dielectric layer containing an insulating resin and a pigment, said dielectric layer carrying a surface static charge of a polarity opposite to that of a charge to be applied for image formation.

Process for electrostatic recording comprising charging dielectric sheet

An electrostatic record material comprising an electroconductive base sheet and a record layer formed on the base sheet and composed mainly of insulating resin, the record material being characterized in that the electroconductive base sheet has an electroconductive layer comprising (1) electron conductive particles produced by coating the particles of an inorganic compound with an electroconductive substance consisting of stannic oxide and a small amount of antimony and (2) a water-soluble adhesive composed of salts of a copolymer of at least 20 mole % of acrylic acid or methacrylic acid monomer.

Electrostatic record material

An electrostatic record material comprising an electroconductive base sheet and a record layer formed on the base sheet and predominantly containing an insulating resin, the record material being characterized in that the electroconductive base sheet has an electroconductive layer comprising:
