ABSTRACT:
A process for processing a DIR coupler-containing silver halide color photographic material for photographing use in a continuous manner with replenishment of a developer is disclosed in which said DIR coupler is a coupler which has in a coupling site a group that functions as a development inhibitor or a development inhibitor precursor upon being eliminated from the coupling active site by color development processing and that will be decomposed to a compound exerting substantially no influences on photographic properties after flowing into a color developing solution, said development inhibitor having a half-value period of 4 hours or shorter than that at a pH of 10.0, and in which the developing solution is replenished in an amount of 700 ml or less per m.sup.2 of developed light-sensitive materials.
