ABSTRACT:
A proofing element containing: (a) a photoconductive layer on an electrically conductive substrate; and (b) overlaying the photoconductive layer, a removable dielectric layer containing thermoplastic polymeric resinous particles which have steric stabilizer groups adhered to the surfaces of said polymeric particles, said steric stabilizer groups being in coordinated association with a charge directing moiety and said charge directing moiety having a charge dissipating agent in association therewith.
A process for applying a removable dielectric layer to a photoconductive substrate comprising the steps of: (a) applying an organosol to a photoconductive substrate, the organosol comprising: a carrier liquid having a dispersion therein of thermoplastic polymeric resinous particles which have steric stabilizer groups adhered to the surfaces of said polymeric particles, said steric stabilizer groups being in coordinated association with a charge directing moiety and said charge directing moiety having a charge dissipating agent in association therewith; and (b) removing the carrier liquid.
