Abstract

Electrostatic recording material is made by coating a conducting paper support with a lacquer comprising at least one unsaturated organic compound and substantially no inert solvent and hardening the lacquer by exposure to radiation such as an electron beam or ultra-violet to form a dielectric layer. The dielectric layer retains charge well at high humidities.
