Abstract
Abstract There is provided a method for processing a silver halide color photographic material which comprises processing the silver halide color photographic material with a color developer containing an aromatic primary amine color developing agent and a specific amino compound. According to this method the stability and color forming property of a color developer are improved so that the increased fogging problem in continuous processing is lessened and the processing time is shortened. There is also provided a color developer composition which can be used as the developer, as it is or after adjusting its composition.
