ABSTRACT:
A method for processing a silver halide color photographic material is disclosed which comprises processing an imagewise exposed silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer containing silver halide having a silver iodide content of at least 2 mol % with a color developing solution, wherein said color developing solution contains at least one compound represented by formula (I), bromide ion in an amount of from 1.0.times.10.sup.-2 to 5.0.times.10.sup.-1 mol per liter and iodide ion in an amount of not more than 1.0.times.10.sup.-4 mol per liter: ##STR1## wherein L represents an alkylene group; A represents a carboxy group, a sulfo group, a phosphone group, a phosphinic acid residual group, a hydroxy group, an unsubstituted amino group or an amino group which is substituted with an alkyl group, an unsubstituted ammonio group or an ammonio group which is substituted with an alkyl group, an unsubstituted carbomoyl group or a carbamoyl group which is substituted with an alkyl group, an unsubstituted sulfamoyl group of a sulfamoyl group is substituted with an alkyl group, or an alkylsulfonyl group; and R represents a hydrogen atom or an alkyl group.
The method according to the present invention provides stable photographic performance and excellent image quality, even when a low level of replenishment is used for color development processing.
