Photographic products and processes using alkali permeable polymeric layers

Claim 1

IN A PROCESS OF FORMING A PHOTOGRAPHIC IMAGE IN COLOR WHEREIN THE LATENT IMAGE CONTAINER IN AN EXPOSED SILVER HALIDE EMULSION LAYER OF A PHOTOSENSITIVE ELEMENT IS DEVELOPED TO PROVIDE AN IMAGEWISE DISTRIBUTION OF COLOR-PROVIDING SUBSTANCE IN SAID EMULSION, AND SAID IMAGEWISE DISTRIBUTION OF COLOR-PROVIDING SUBSTANCES IS TRANSFERRED BY AN AQUEOUS ALKALINE PROCESSING SOLUTION TO A SUPERPOSED IMAGE-RECEIVING LAYER TO IMPART TO SAID IMAGE-RECEIVING LAYER A COLOR-IMAGE, THE IMPROVEMENT OF HAVING THE COLOR-PROVIDING SUBSTANCE IN A POLYMERIC LAYER BEHIND THE SILVER HALIDE EMULSION LAYER AND DURING PROCESSING, PERMEATING SAID PHOTOSENSITIVE ELEMENT WITH SAID AQUEOUS ALKALINE PROCESSING SOLUTION AND SOLUBILIZING SAID COLOR-PROVIDING SUBSTANCE FROM SAID POLYMERIC LAYER, SAID POLYMERIC LAYER COMPRISING A POLYMER SELECTED FROM THE GROUP CONSISTING OF (A) N-ALKYL-A,B-UNSATURATED CARBOXAMIDE HOMOPOLYMERS, (B) COPOLYMERS OF A FIRST N-ALKYLA,B-UNSATURATED CARBOXAMIDE MONOMER WITH AT LEAST A SECOND N-ALKYL-A,B-UNSATURATED CARBOXAMIDE MONOMER AND (C) COPOLYMERS OF N-ALKYL-A,B-UNSATURATED CARBOXAMIDES WITH N-HYDROXYALKYL-A,B-UNSATURATED CARBOXAMIDES, THE CARBOXAMIDES USED TO PREPARE THE POLYMERS OF SAID POLYMERIC LAYER BEING DERIVATIVES OF A,B-UNSATURATED ALIPHATIC MONOCARBOXYLIC ACIDS COMPRISING LESS THAN SIX CARBON ATOMS AND THE N-ALKYL- AND N-HYDROXYALKYL-SUBSTITUENTS OF SAID CARBOXAMIDES USED TO PREPARE THE POLYMERS IN SAID POLYMERIC LAYER COMPRISING LESS THAN FIVE CARBON ATOMS.
