Complexed p-phenylenediamine containing photographic element and development process therefor |
| abstract |
COLOR PHOTOGRAPHIC ELEMENTS COMPRISING A SUPPORT COATED WITH AT LEAST ONE HYDROPHILIC COLLOID LAYER CONTAINING LIGHT-SENSITIVE SILVER HALIDE AND A NONDIFFUSIBLE COUPLER THAT REACTS WITH OXIDIZED AROMATIC PRIMARY AMINE COLOR DEVELOPING AGENT TO FORM A NONDIFFUSIBLE DYE AND COATED ON THE SAME SIDE OF THE SUPPORT AT LEAST ONE HYDROPHILIC COLLOID LAYER CONTAINING A PHOTOGRAPHICALLY COMPATIBLE, INACTIVE COLOR DEVELOPING AGENT PRECURSOR FORMED BY REACTING (1) A WATER-SOLUBLE POLYVALENT METAL SALT WITH (2) A WATER-SOLUBLE AND DIFFUSIBLE P-PHENYLENEDIAMINE COLOR DEVELOPING AGENT OR ACID SALT THEREOF. THE IMMEDIATE ELEMENTS HAVE GOOD STABILITY WITH SUBSTANTIALLY NO CHANGE PRODUCED BY TTHE COLOR DEVELOPING AGENT PRECURSOR DURING STORAGE AND ARE ADVANTAGEOUSLY COLOR DEVELOPED BY CONTACTING THE PHOTOGRAPHIC ELEMENT WITH AN AQUEOUS ALKALINE ACTIVATOR SOLUTION WHICH RAPIDLY RELEASES ACTIVE COLOR DEVELOPING AGENT FROM THE PRECURSOR. |
