Photographic processes and compositions useful therein

Claim 1

A PHOTOGRAPHIC PROCESS FOR FORMING BY TRANSFER A POSITIVE PRINT OF A LATENT IMAGE CONTAINED IN A SILVER HALIDE STRATUM, WHICH PROCESS COMPRISES THE STEPS OF: APPLYING IN A THIN LAYER, BETWEEN AN EXPOSED SILVER HALIDE STRATUM, CONTAINING SOFT GELATIN AND A SILVER-RECEPTIVE STRATUM, AN AQUEOUS SOLUTION CONTAINING FROM 1 TO 8% OF A SILVER HALIDE DEVELOPER FROM 0.3 TO 10% OF A SILVER HALIDE SOLVENT AND FROM 1 TO 8% OF A GELATIN HARDENING AGENT SELECTED FROM THE GROUP CONSISTING OF SULFATES, SULFITES, CHROMATES, ALUMS, ALDHEYDES AND KETONES, TO INITIATE A PREDETERMINED PERIOD, SAID SOFT GELATIN INITIALLY HAVING A SETTING POINT RANGING FROM 75* TO 90*F. AT 100% RELATIVE HUMIDITY AND BEING CAPABLE OF REMOVING MOISTURE FROM SAID LAYER BY ADSORPTION SO AS TO REDUCE THE DISTANCE BETWEEN SAID SILVER HALIDE STRATUM AND SAID SILVER-RECEPTIVE STRATUM DURING THE INITIAL STAGES OF SAID PREDETERMINED PERIOD SUBSTANTIALLY TO A MINIMUM DISTANCE BETWEEN SAID SILVER HALIDE STRATUM AND SAID SILVER-RECEPTIVE STRATUM OCCURRING AT THE END OF SAID PREDETERMINED PERIOD, SAID HARDENING AGENT PRESENT IN SAID AQUEOUS SOLUTION GRADUALLY INCREASING THE HARDNESS OF SAID SILVER HALIDE STRATUM THROUGHOUT SAID PREDETERMINED PERIOD TO A SETTING POINT OF AT LEAST 100*F. AT 100% HUMIDITY, TRANSFERRING A COMPLEX SILVER SLAT FORMED BY THE REACTION OF SAID SILVER HALIDE SOLVENT WITH UNEXPOSED SILVER HALIDE FROM SAID SILVER HALIDE STRATUM TO SAID SILVER-RECEPTIVE STRATUM TO FORM THEREIN A POSITIVE PRINT, AND STRIPPING SAID SILVER HALIDE STRATUM FROM SAID SILVER-RECEPTIVE STRATUM CARRYING A POSITIVE PRINT TO TERMINATE SAID PREDETERMINED PERIOD.
