ABSTRACT:
A homogeneous, single part slurry-form color photographic developer composition for use in color photographic processing is provided which comprises a defined compound of Formula (I) and, a p-phenylenediamine derivative, and contains a discontinuous solid phase distributed in a single liquid phase. The slurry is used by being completely dissolved in water, and diluted to make a working tank developer or developer replenisher solution, typically with a pH of about 10.4 or less for the working tank and 12.0 or less for the replenisher. The slurry is compact, homogeneous, easy to dispense, has excellent water solubility, and remains free of degradation during long-term storage. A process for developing photographic color silver halide photosensitive material with the slurry is also provided, as well as a process for making the slurry.
