Abstract (en)
Silver halide photographic element comprising a support having coated thereon red-, green- and blue-sensitive silver halide emulsion layers comprising, respectively, cyan, magenta and yellow dye-forming couplers, wherein the green-sensitive layer comprises three green-sensitive layers having different sensitivity, an uppermost green-sensitive layer being more sensitive than an intermediate green-sensitive layer which is more sensitive than a lowermost green-sensitive layer, the layers arranged with the lowermost green-sensitive layer being closer to the support, the intermediate green-sensitive layer being adjacent said lowermost green-sensitive layer and the uppermost green-sensitive layer being above the intermediate green-sensitive layer, characterized in that the uppermost green-sensitive emulsion layer comprises 4-equivalent 5-pyrazolone magenta dye-forming couplers, and the intermediate and the lowermost green-sensitive emulsion layers comprise 2-equivalent 4-arylthio-5-pyrazolone magenta dye-forming couplers.
