Photographic product comprising an additive color screen, a silver halide layer, and a rupturable container, and a process of additive color photography

Claim 2

IN A COLOR PHOTOGRAPHIC PROCESS MAKING USE OF AN ADDITIVE COLOR SCREEN FOR TAKING AND VIEWING PURPOSES, THE STEPS OF EXPOSING THROUGH SAID SCREEN A COLOR SENSITIVE SILVER HALIDE EMULSION LAYER ARRANGED IN SUPERPOSED RELATION TO SAID SCREEN TO FORM A NEGATIVE LATENT IMAGE IN SAID EMULSION LAYER SAID SCREEN COMPRISING A LAYER OF A TRANSPARENT MATERIAL CARRYING COLORED FILTER MEDIA WHICH ARE ARRANGED TO PROVIDE A SCREEN PATTERN AND WHICH ARE OF AT LEAST TWO DIFFERENT COLORS CORRESPONDING TO THE ADDITIVE COLORS DESIRED FOR SAID SCREEN, DEVELOPING THE LATENT IMAGE IN SAID EMULSION LAYER TO SILVER BY ABSORBING IN SAID EMULSION LAYER A LIQUID REAGENT COMPRISING A DEVELOPER AND A SILVER HALIDE SOLVENT WHICH FORMS A SOLUBLE SILVER COMPLEX WITH UNEXPOSED SILVER HALIDE, TRANSFERRING FROM SAID EMULSION LAYER, BY IMBITION, AT LEAST PART OF SAID SILVER COMPLEX TO AT LEAST A STRATUM OF A PERMEABLE TRANSPARENT LAYER CONSTITUTING A RECEIVING LAYER FOR SAID COMPLEX AND ARRANGED IN SUPERPOSED RELATION TO SAID EMULSION LAYER ON THE COLOR SCREEN SIDE OF THE EMULSION LAYER WHEREBY TO PROVIDE IN CONJUNCTION WITH SAID EMULSION LAYER AND SAID COLOR SCREEN A UNITARY STRUCTURE, HOLDING SAID LAYERS FIXED AGAINST ANY APPRECIABLE RELATIVE MOVEMENT IN A DIRECTION PARALLEL TO THE PLANES OF SAID LAYERS WHILE TRANSPORTING TO SAID STRATUM A QUANTITY OF SAID SOLUBLE COMPLEX SUFFICIENT TO FORM IN SAID STRATUM A POSITIVE SILVER IMAGE OF SAID EMULSION IMAGE, AND THEREAFTER SEPARATING SAID EMULSION LAYER FROM SAID UNITARY STRUCTURE WHILE RETAINING SAID FILTER MEDIA AND SAID RECEIVING LAYER IN FIXED RELATION ONE TO THE OTHER.

Claim 3
