  • Patent number: 5741631
    Abstract: A process for the formation of a dye image by a redox amplification process in an imagewise exposed photographic color material having at least one silver halide layer and associated therewith a dye image-forming color coupler, comprises treating the material in a color developer solution containing a color developing agent and hydroxylamine as developing agent preservative. The color developing solution is replenished directly as solids or liquid concentrates with or without additional water. The process is carried out in a tank in which the ratio of the tank volume to maximum area of material accommodatable therein is less than 11 dm.sup.3 /m.sup.2.
