Abstract
A multilayer color reversal light-sensitive material is described, which can provide dye images having improved sharpness and graininess without a drop in color reproducibility, by employing a specific arrangement and construction of emulsion layers in its multi-layer structure, viz., a material comprising a support, a yellow filter layer, a group of green-sensitive emulsion layers, and a group of red-sensitive emulsion layers, wherein said emulsion layer groups are positioned nearer to the support than the yellow filter layer, each of the emulsion layer groups comprises at least two adjacent layers including a high-sensitivity silver halide emulsion layer containing silver halide grains having an average size of from 0.6.mu. to 2.0.mu. and a low-sensitivity silver halide emulsion layer containing silver halide grains having an average grain size of from 0.1.mu. to 0.5.mu., and at least one of the green-sensitive low-sensitivity emulsion layer or the red-sensitive low-sensitivity emulsion layer is positioned farther from the support than the high-sensitivity emulsion layer of the corresponding emulsion layer group.
