摘要： A silver halide color negative photographic lightsentive material comprises at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer on a support. The lightsensitive material has an ISO speed of 640 or more, the total silver content of 3.0 to 9.0 g/m2. Each of the red-sensitive emulsion layer, green-sensitive emulsion layer and blue-sensitive emulsion layer comprises two or more silver halide emulsion sub-layers having the same color sensitivity but different in speed to each other, and each of the red-sensitive sub-layer having the highest speed, green-sensitive sub-layer having the highest speed and blue-sensitive emulsion sub-layer having the highest speed has a silver content of 0.3 to 1.3 g/m2. At least two sub-layers selected from the red-sensitive sub-layer having the highest sensitivity, green-sensitive sub-layer having the highest sensitivity and blue-sensitive sub-layer having the highest speed contain silver halide grains in which tabular silver halide grains occupy 50% or more of the total projected area of all the silver halide grains in the sub-layer, and the tabular grains have an average aspect ratio of 8 or more.
