Abstract (en)

[origin: EP0107817A2] A multilayer silver halide reversal color photographic material is disclosed. The material has on a support three or more silver halide emulsion layers having the same color sensitivity but different photographic sensitivities. The highest sensitivity emulsion layer and the second highest sensitivity emulsion layer among the above-described silver halide emulsion layers have silver halide emulsions of an iodide content of 4.5 mole % or less and such a grain size distribution that 85% or more, by number or by weight, of whole silver halide grains in the emulsion have sizes which are within +/- 40% of its mean grain size. The material provides good granularity of the resulting dye image.
