Multicolor reproduction using light sensitive diazo oxides

Claim 1

A METHOD OF PREPARING A COLORED PRODUCTION BY THE SUPERIMPOSITION OF DYE IMAGES CORRESPONDING TO AT LEAST TWO OF THE PRIMARY COLOR ASPECTS OF A SUBJECT WHICH COMPRISES EXPOSING BY LIGHT TO A COLOR SEPARATION NEGATIVE, A LIGHT-SENSITIVE MATERIAL COMPRISING A BASE, A LACQUER LAYER ON SAID BASE COMPRISING A HOMOGENEOUS MIXTURE OF A CO-POLYMER OF A VINYL ALKYL ETHER AND MALEIC ANHYDRIDE AND A HYDROPHOBIC RESIN COMPATIBLE THEREWITH AND AN OVERCOATING ON SAID LACQUER LAYER OF A WATERINSOLUBLE ADHESIVE RESIN AND A LIGHT-SENSITIVE, WATER-INSOLUBLE DIAZO OXIDE, DEVELOPING THROUGH LOCALLY REMOVING, BY MEANS OF A DEVELOPER COMPRISING A LIQUID ALIPHATIC POLYHYDROXY COMPOUND, THE OVERCOATING WHERE EXPOSED TO LIGHT AND IMPARTING HYDROPHILIC CHARACTER TO THE LACQUER LAYER IN THE EXPOSED AREAS BY TREATMENT WITH HYDROXY COMPOUND, DYEING THE EXPOSED AREAS WITH A COLOR MATERIAL SUBSTANTIVE TO THE HYDROPHILIC AREAS OF SAID LACQUER LAYER, REMOVING THE RESIDUAL OVERCOATING FROM THE LACQUER LAYER, RESENSITIZING THE LACQUER LAYER BY REAPPLICATION OF THE OVERCOATING OVER THE ENTIRE AREA OF THE LACQUER LAYER, EXPOSING THE RESENSITIZED LAYER TO A DIFFERENT COLOR SEPARATION NEGATIVE OF THE SAME SUBJECT, REPEATING THE STEPS OF DEVELOPING AND IMPARTING HYDROPHILIC CHARACTER TO THE LACQUER LAYER IN THE EXPOSED AREAS AND DYEING THE EXPOSED AREAS WITH A DIFFERENT COLORANT SUBSTANTIVE TO THE HYDROPHILIC AREAS OF SAID LACQUER LAYER, REMOVING THE RESIDUAL OVERCOATING, AND REPEATING THE PROCESS OUTLINED ACCORDING TO THE NUMBER OF SEPARATION NEGATIVES REQUIRED TO PRODUCE THE FINAL RESULT.

Claim 2

A METHOD OF PREPARING A COLORED PRODUCTION BY THE SUPERIMPOSITION OF DYE IMAGES CORRESPONDING TO AT LEAST TWO OF THE PRIMARY COLOR ASPECTS OF A SUBJECT WHICH COMPRISES EXPOSING BY LIGHT TO A COLOR SEPARATION NEGATIVE, A LIGHT-SENSITIVE MATERIAL COMPRISING A BASE, A LACQUER LAYER ON SAID BASE COMPRISING A HOMOGENEOUS MIXTURE OF A CO-POLYMER OF A VINYL ALKYL ETHER AND MALEIC ANHYDRIDE AND A HYDROPHOBIC RESIN COMPATIBLE THEREWITH AND AN OVERCOATING ON SAID LACQUER LAYER OF A WATERINSOLUBLE ADHESIVE RESIN AND A LIGHT-SENSITIVE, WATER-INSOLUBLE DIAZO OXIDE, DEVELOPING THROUGH LOCALLY REMOVING, BY MEANS OF A DEVELOPER COMPRISING A LIQUID ALIPHATIC POLYHYDROXY COMPOUND, THE OVERCOATING WHERE EXPOSED TO LIGHT AND IMPARTING HYDROPHILIC CHARACTER TO THE LACQUER LAYER IN THE EXPOSED AREAS BY TREATMENT WITH HYDROXY COMPOUND, DYEING THE EXPOSED AREAS WITH A COLOR MATERIAL SUBSTANTIVE TO THE HYDROPHILIC AREAS OF SAID LACQUER LAYER, REMOVING THE RESIDUAL OVERCOATING FROM THE LACQUER LAYER, RESENSITIZING THE LACQUER LAYER BY REAPPLICATION OF THE OVERCOATING OVER THE ENTIRE AREA OF THE LACQUER LAYER, EXPOSING THE RESENSITIZED LAYER TO A DIFFERENT COLOR SEPARATION NEGATIVE OF THE SAME SUBJECT, REPEATING THE STEPS OF DEVELOPING AND IMPARTING HYDROPHILIC CHARACTER TO THE LACQUER LAYER IN THE EXPOSED AREAS AND DYEING THE EXPOSED AREAS WITH A DIFFERENT COLORANT SUBSTANTIVE TO THE HYDROPHILIC AREAS OF SAID LACQUER LAYER, REMOVING THE RESIDUAL OVERCOATING, AND REPEATING THE PROCESS OUTLINED ACCORDING TO THE NUMBER OF SEPARATION NEGATIVES REQUIRED TO PRODUCE THE FINAL RESULT.
