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.
Claims14
A method of making an electrostatic recording material which comprises coating an electrically conducting paper support with a composition hardenable by exposure to radiation to produce a dielectric coating capable of recording a latent electrostatic image, the composition comprising at least one unsaturated organic compound and substantially no inert solvent, and exposing the coated support to radiation to harden the coating.
An electrostatic recording material comprising an electrically conducting paper support applied thereto a dielectric coating applied thereto capable of recording an electrostatic latent image, the dielectric coating comprising a composition hardened by exposure to radiation and comprising at least one unsaturated organic compound and substantially no inert solvent.
