摘要： A silver halide color photographic material having at least three light-sensitive silver halide emulsion layers, each sensitive in a different wavelength region. At least one of the silver halide emulsion layers contains at least one adsorbable reducing compound represented by a hydroquinone containing a group capable of promoting adsorption to silver halide grains and a silver halide emulsion having a silver chloride content of at least 90 mol %. The photographic material is well adapted for rapid processing and maintains constant sensitivity with a change in humidity upon exposure and when stored for a long period of time prior to use.
