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/m . 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/m . 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.

Silver halide color photographic lightsensitive material

A silver halide photographic material is disclosed, comprising a support having provided thereon at least one silver halide emulsion layer, wherein the silver halide emulsion layer contains, in the dispersion medium phase of the emulsion, one or more kinds of inorganic fine particles having a refractive index the total weight of the fine particles contained in the unit volume of the dispersion medium phase is from 1.0 to 95 wt %, the dispersion medium phase containing the fine particles is substantially transparent to the photosensitive peak wavelength light of the emulsion layer, and the photographic material is exposed and processed in the development process comprising at least a developing step and a fixing step.
