Abstract (en)

A silver halide multilayer reversal color photographic material is disclosed. The material has a blue-sensitive, a green-sensitive and a red-sensitive silver halide emulsion layers at least one of which forms a group consisting of two or three emulsion layers differing in photographic sensitivity. The emulsion layer group contains silver in its high sensitivity constituent layer or in the combination of its high sensitivity constituent layer and its intermediate sensitivity constituent layer in such an amount that it comprises 40 to 80% of the total silver amount in the emulsion layer group. The emulsion layer group containing silver iodide in its high sensitivity constituent layer or the combination of its high sensitivity constituent layer and its intermediate sensitivity layer in such a content that a proportion of the iodide to the all halides in the high sensitivity constituent layer or the combination of the high sensitivity constituent layer and the intermediate sensitivity constituent layer is smaller than that in its low sensitivity constituent layer by 0.3 mole % or more.
