Abstract
An electrostatic recording material having excellent recording characteristics is obtained by coating an electrically conductive substrate with a coating composition comprising an insulating polymer and pigment particles on which is adsorbed a fatty acid having at least five carbon atoms, ester or salt thereof, or resin acid or salt thereof.
Claims12
An electrostatic recording material consisting essentially of an electrically conductive substrate and a dielectric layer formed on a surface thereof, said dielectric layer being essentially formed with an insulating polymeric material and pigment particles, said pigment particles having an average particle size of about 0.5 to 10 .mu..phi., said pigment particles carrying thereon a surface treating agent which is a member selected from the group consisting of fatty acids having at least 5 carbon atoms, polyhydric alcohol esters of said fatty acids, ammonium salts and metal salts of said fatty acids, resin acids, metal salts of said resin acids and mixtures of the foregoing
