Abstract
An electrostatic recording medium comprising a support, a conductive layer formed on one surface of the support and made of zinc oxide dispersed in a combination of a cationic polyelectrolyte and a non-conductive binder resin, and a dielectric layer formed on the conductive layer. The cationic polyelectrolyte is contained in an amount of not smaller than 30% by weight of the total of the polyelectrolyte and the binder resin.
Claims15
An electrostatic recording medium comprising a support, a conductive layer coated on one surface of said support, said conductive layer consisting essentially of zinc oxide dispersed in a combination of not less than 30% but not greater than 95% by weight of a cationic polyelectrolyte, with the balance being a non-conductive resin, and a dielectric layer formed on the conductive layer.
