Xerographic plate made by cast coating

Claim 1

THE METHOD OF RECORDING XEROGRAPHIC IMAGES, SAID METHOD HAVING A RESOLUTION CAPABILITY IN EXCESS OF 100 LINES PER MM., COMPRISING FORMING A LIQUID DISPERSION OF PHOTOCONDUCTIVE ZINC OXIDE PARTICLES IN A SOLVENT SOLUTION OF A RESIN, COATING SAID DISPERSION IN A UNIFORM LAYER ONTO A SPECULAR AND NON-ADHERING SURFACE, THEREAFTER AND PRIOR TO DRYING SAID COATING LAYER ADHERING TO THE OUTER SURFACE LAYER OF SAID COATNG LAYER OPPOSITE TO SAID SURFACE LAYER ON SAID SPECULAR SURFACE A PAPER SUPPORT LAYER, HARDENING SAID RESIN IN CONTACT WITH SAID SPECULAR SURFACE AND SAID PAPER SUPPORT LAYER BY EVAPORATING SAID SOLVENT FROM SAID LAYER ADHERING TO SAID PAPER SUPPORT LAYER TO FORM A HARDENED RESIN COATING LAYER, SEPARATING SAID COATING LAYER ADHERING TO SAID PAPER SUPPORT LAYER FROM SAID SPECULAR SURFACE, SAID COATING LAYER HAVING SAID PHOTOCONDUCTIVE PARTICLES DISPERSED THERETHROUGH AND HAVING A SINGLE SPECULARLY SMOOTH ELECTROSTATICALLY DEVELOPABLE WORKING SURFACE ALONG WHICH SAID PARTICLES ARE ORIENTED TO FORM A REGION OF HIGHER AND MORE UNIFORM PARTICLE DENSITY THAN THE REMAINDER OF SAID COATING LAYER, DEPOSITING A UNIFORM ELECTROSTATIC CHARGE ONTO SAID WORKING SURFACE CREATING A SENSITIVE XEROGRAPHIC PLATE, EXPOSING SAID SURFACE TO A PATTERN OF LIGHT AND SHADOW TO FORM AN ELECTROSTATIC LATENT IMAGE THEREON CONFORMING IN CONFIGURATION TO SAID LIGHT AND SHADOW PATTERN, AND ELECTROSTATICALLY DEVELOPING SAID ELECTROSTATIC LATENT IMAGE ON SAID WORKING SURFACE.

Claim 2

THE METHOD OF RECORDING XEROGRAPHIC IMAGES, SAID METHOD HAVING A RESOLUTION CAPABILITY IN EXCESS OF 100 LINES PER MM., COMPRISING FORMING A LIQUID DISPERSION OF PHOTOCONDUCTIVE ZINC OXIDE PARTICLES IN A SOLVENT SOLUTION OF A RESIN, COATING SAID DISPERSION IN A UNIFORM LAYER ONTO A SPECULAR AND NON-ADHERING SURFACE, THEREAFTER AND PRIOR TO DRYING SAID COATING LAYER ADHERING TO THE OUTER SURFACE LAYER OF SAID COATNG LAYER OPPOSITE TO SAID SURFACE LAYER ON SAID SPECULAR SURFACE A PAPER SUPPORT LAYER, HARDENING SAID RESIN IN CONTACT WITH SAID SPECULAR SURFACE AND SAID PAPER SUPPORT LAYER BY EVAPORATING SAID SOLVENT FROM SAID LAYER ADHERING TO SAID PAPER SUPPORT LAYER TO FORM A HARDENED RESIN COATING LAYER, SEPARATING SAID COATING LAYER ADHERING TO SAID PAPER SUPPORT LAYER FROM SAID SPECULAR SURFACE, SAID COATING LAYER HAVING SAID PHOTOCONDUCTIVE PARTICLES DISPERSED THERETHROUGH AND HAVING A SINGLE SPECULARLY SMOOTH ELECTROSTATICALLY DEVELOPABLE WORKING SURFACE ALONG WHICH SAID PARTICLES ARE ORIENTED TO FORM A REGION OF HIGHER AND MORE UNIFORM PARTICLE DENSITY THAN THE REMAINDER OF SAID COATING LAYER, DEPOSITING A UNIFORM ELECTROSTATIC CHARGE ONTO SAID WORKING SURFACE CREATING A SENSITIVE XEROGRAPHIC PLATE, EXPOSING SAID SURFACE TO A PATTERN OF LIGHT AND SHADOW TO FORM AN ELECTROSTATIC LATENT IMAGE THEREON CONFORMING IN CONFIGURATION TO SAID LIGHT AND SHADOW PATTERN, AND ELECTROSTATICALLY DEVELOPING SAID ELECTROSTATIC LATENT IMAGE ON SAID WORKING SURFACE.
