Claim 1

Independent Claim 295 words

A PHOTOGRAPHIC PROCESS FOR FORMING, BY TRANSFER, A POSITIVE PRINT OF A LATENT IMAGE CONTAINED IN THE SILVER HALIDE EMULSION OF A PHOTOSENSITIVE ELEMENT WHEREIN A SINGLE APPLICATION OF LIQUID TO SAID ELEMENT IS EFFECTIVE TO GIVE A FINISHED PRINT SUFFICIENTLY STABLE TO REQUIRE NO SUBSEQUENT LIQUID STABILIZING TREATMENTS, WHICH PROCESS COMPRISES THE STEPS OF BRINGING A RELATIVELY UNIFORM LAYERWISE DISTRIBUTION OF A PROCESSING LIQUID INTO CONTACT WITH THE PHOTOSENSITIVE ELEMENT SO AS TO PERMEATE SAID EMULSION WITH SAID LIQUID, SAID LAYERWISE DISTRIBUTION OF PROCESSING LIQUID PROVIDING THE ENTIRE MASS OF LIQUID FOR PERFORMING SAID PROCESS; PROVIDING A PRINT-RECEIVING ELEMENT IN SUPERPOSED RELATION WITH THE PHOTOSENSITIVE ELEMENT, SAID PRINT-RECEIVING ELEMENT BEING AT LEAST PARTIALLY PERMEABLE TO THE PROCESSING LIQUID AND THE LAYERWISE DISTRIBUTION OF THE PROCESSING LIQUID BEING CONFINED BETWEEN THE OUTER SURFACES OF SAID SUPERPOSED ELEMENTS THROUGHOUT THE PROCESSING, SAID PROCESSING LIQUID CONTAINING, AFTER PERMEATION OF SAID SILVER HALIDE LAYER, ALL OF THE REAGENT, INCLUDING A SILVER HALIDE DEVELOPER AND AN ALKALI, FOR DEVELOPING THE LATENT IMAGE IN THE SILVER HALIDE EMULSION AND FOR FORMING A POSITIVE PRINT OF THE SUBJECT MATTER OF SAID LATENT IMAGE UPON SAID PRINT-RECEIVING ELEMENT, SAID DEVELOPER BEING CHARACTERIZED BY ITS PROPENSITY FOR OXIDIZING IN AN ALKALINE ENVIRONMENT TO FORM STAINS; AND INTRODUCING INTO THE ALKALINE PROCESSING LIQUID, SUBSEQUENT TO ITS CONTACT WITH THE PHOTOSENSITIVE ELEMENT, A SUBSTANCE OF ACID REACTION IN SUFFICIENT CONCENTRATION TO REDUCE THE ALKALINITY OF SAID PROCESSING LIQUID TO A PH AT WHICH THE UNUSED DEVELOPER THEREIN IS SUBSTANTIALLY INCAPABLE OF OXIDATION TO FORM A STAIN IN SAID POSITIVE PRINT, SAID SUBSTANCE OF ACID REACTION BEING DISSOLVED FROM A PERMEATED PORTION OF ONE OF SAID ELEMENTS AND BEING PRESENT IN SAID PROCESSING LIQUID IN ADDITION TO ALL OF THE REAGENTS FOR FORMING THE TRANSFER PRINT.

Claim 2

Dependent Claim 295 words

A PHOTOGRAPHIC PROCESS FOR FORMING, BY TRANSFER, A POSITIVE PRINT OF A LATENT IMAGE CONTAINED IN THE SILVER HALIDE EMULSION OF A PHOTOSENSITIVE ELEMENT WHEREIN A SINGLE APPLICATION OF LIQUID TO SAID ELEMENT IS EFFECTIVE TO GIVE A FINISHED PRINT SUFFICIENTLY STABLE TO REQUIRE NO SUBSEQUENT LIQUID STABILIZING TREATMENTS, WHICH PROCESS COMPRISES THE STEPS OF BRINGING A RELATIVELY UNIFORM LAYERWISE DISTRIBUTION OF A PROCESSING LIQUID INTO CONTACT WITH THE PHOTOSENSITIVE ELEMENT SO AS TO PERMEATE SAID EMULSION WITH SAID LIQUID, SAID LAYERWISE DISTRIBUTION OF PROCESSING LIQUID PROVIDING THE ENTIRE MASS OF LIQUID FOR PERFORMING SAID PROCESS; PROVIDING A PRINT-RECEIVING ELEMENT IN SUPERPOSED RELATION WITH THE PHOTOSENSITIVE ELEMENT, SAID PRINT-RECEIVING ELEMENT BEING AT LEAST PARTIALLY PERMEABLE TO THE PROCESSING LIQUID AND THE LAYERWISE DISTRIBUTION OF THE PROCESSING LIQUID BEING CONFINED BETWEEN THE OUTER SURFACES OF SAID SUPERPOSED ELEMENTS THROUGHOUT THE PROCESSING, SAID PROCESSING LIQUID CONTAINING, AFTER PERMEATION OF SAID SILVER HALIDE LAYER, ALL OF THE REAGENT, INCLUDING A SILVER HALIDE DEVELOPER AND AN ALKALI, FOR DEVELOPING THE LATENT IMAGE IN THE SILVER HALIDE EMULSION AND FOR FORMING A POSITIVE PRINT OF THE SUBJECT MATTER OF SAID LATENT IMAGE UPON SAID PRINT-RECEIVING ELEMENT, SAID DEVELOPER BEING CHARACTERIZED BY ITS PROPENSITY FOR OXIDIZING IN AN ALKALINE ENVIRONMENT TO FORM STAINS; AND INTRODUCING INTO THE ALKALINE PROCESSING LIQUID, SUBSEQUENT TO ITS CONTACT WITH THE PHOTOSENSITIVE ELEMENT, A SUBSTANCE OF ACID REACTION IN SUFFICIENT CONCENTRATION TO REDUCE THE ALKALINITY OF SAID PROCESSING LIQUID TO A PH AT WHICH THE UNUSED DEVELOPER THEREIN IS SUBSTANTIALLY INCAPABLE OF OXIDATION TO FORM A STAIN IN SAID POSITIVE PRINT, SAID SUBSTANCE OF ACID REACTION BEING DISSOLVED FROM A PERMEATED PORTION OF ONE OF SAID ELEMENTS AND BEING PRESENT IN SAID PROCESSING LIQUID IN ADDITION TO ALL OF THE REAGENTS FOR FORMING THE TRANSFER PRINT.

Claim 3

Dependent Claim 265 words

A PHOTOGRAPHIC PRODUCT COMPRISING A LIQUID-CONFINING LAYER, INCLUDING AT LEAST A PHOTOSENSITIVE PORTION, SAID PHOTOSENSITIVE PORTION COMPRISING SILVER HALIDE AS THE PHOTOSENSITIVE MATERIAL THEREOF, ANOTHER LIQUID-CONFINING LAYER AND A RUPTURABLE CONTAINER HOLDING A LIQUID, SAID LAYERS AND SAID CONTAINER BEING ASSOCIATED TOGETHER SO AS TO PERMIT SAID LAYERS TO BE SUPERPOSED WITH SAID LIQUID HELD BY SAID CONTAINER POSITO WET SAID LAYERS AND WITH SAID CONTAINER SO AS NOT TIONED FOR RELEASING SAID LIQUID BETWEEN SAID LAYERS, SAID PRODUCT CONTAINING ALL OF THE REAGENTS, INCLUDING A SILVER HALIDE DEVELOPER AND AN ALKALI IN SUFFICIENT QUANTITY TO DEVELOP A LATENT IMAGE IN SAID PHOTOSENSITIVE PORTION AND TO PROVIDE A LAYER OF SAID PRODUCT, OTHER THAN SAID PHOTOSENSITIVE LAYER, WITH A POSITIVE TRANSFER PRINT OF THE SUBJECT MATTER OF SAID LATENT IMAGE, SAID REAGENTS BEING RENDERED EFFECTIVE UPON THE RELEASE OF SAID LIQUID FROM THE RUPTURABLE CONTAINER, SAID SILVER HALIDE DEVELOPER TENDING TO OXIDIZE AND FORM STAINS IN AN ALKALINE ENVIRONMENT, SAID PRODUCT CONTAINING, IN ADDITION TO ALL OF SAID REAGENTS FOR FORMING A TRANSFER PRINT, A SUBSTANCE OF ACID REACTION WHICH IS CARRIED BY ONE OF THE LAYERS OF SAID PRODUCT IN A POSITION TO BE DISSOLVED IN SAID LIQUID UPON THE RELEASE THEREOF, SAID SUBSTANCE OF ACID REACTION BEING OPERATIVE TO REDUCE THE ALKALINITY OF THE LIQUID AT A RATE SUBSTANTIALLY SLOWER THAN THE RATE AT WHICH THE DEVELOPING REACTION TAKES PLACE AND BEING SUFFICIENT IN QUANTITY TO REDUCE THE ALKALINITY OF THE PROCESSING LIQUID TO A PH AT WHICH THE DEVELOPER IS SUBSTANTIALLY INCAPABLE OF OXIDIZING TO FORM STAINS IN SAID POSITIVE TRANSFER PRINT.

Claim 4

Dependent Claim 265 words

A PHOTOGRAPHIC PRODUCT COMPRISING A LIQUID-CONFINING LAYER, INCLUDING AT LEAST A PHOTOSENSITIVE PORTION, SAID PHOTOSENSITIVE PORTION COMPRISING SILVER HALIDE AS THE PHOTOSENSITIVE MATERIAL THEREOF, ANOTHER LIQUID-CONFINING LAYER AND A RUPTURABLE CONTAINER HOLDING A LIQUID, SAID LAYERS AND SAID CONTAINER BEING ASSOCIATED TOGETHER SO AS TO PERMIT SAID LAYERS TO BE SUPERPOSED WITH SAID LIQUID HELD BY SAID CONTAINER POSITO WET SAID LAYERS AND WITH SAID CONTAINER SO AS NOT TIONED FOR RELEASING SAID LIQUID BETWEEN SAID LAYERS, SAID PRODUCT CONTAINING ALL OF THE REAGENTS, INCLUDING A SILVER HALIDE DEVELOPER AND AN ALKALI IN SUFFICIENT QUANTITY TO DEVELOP A LATENT IMAGE IN SAID PHOTOSENSITIVE PORTION AND TO PROVIDE A LAYER OF SAID PRODUCT, OTHER THAN SAID PHOTOSENSITIVE LAYER, WITH A POSITIVE TRANSFER PRINT OF THE SUBJECT MATTER OF SAID LATENT IMAGE, SAID REAGENTS BEING RENDERED EFFECTIVE UPON THE RELEASE OF SAID LIQUID FROM THE RUPTURABLE CONTAINER, SAID SILVER HALIDE DEVELOPER TENDING TO OXIDIZE AND FORM STAINS IN AN ALKALINE ENVIRONMENT, SAID PRODUCT CONTAINING, IN ADDITION TO ALL OF SAID REAGENTS FOR FORMING A TRANSFER PRINT, A SUBSTANCE OF ACID REACTION WHICH IS CARRIED BY ONE OF THE LAYERS OF SAID PRODUCT IN A POSITION TO BE DISSOLVED IN SAID LIQUID UPON THE RELEASE THEREOF, SAID SUBSTANCE OF ACID REACTION BEING OPERATIVE TO REDUCE THE ALKALINITY OF THE LIQUID AT A RATE SUBSTANTIALLY SLOWER THAN THE RATE AT WHICH THE DEVELOPING REACTION TAKES PLACE AND BEING SUFFICIENT IN QUANTITY TO REDUCE THE ALKALINITY OF THE PROCESSING LIQUID TO A PH AT WHICH THE DEVELOPER IS SUBSTANTIALLY INCAPABLE OF OXIDIZING TO FORM STAINS IN SAID POSITIVE TRANSFER PRINT.
