摘要:
A silver halide photographic material comprising a support having coated thereon at least one blue-sensitive layer containing a yellow coupler, at least one green-sensitive layer containing a magenta coupler and at least one red-sensitive layer containing a cyan coupler, wherein on each of the characteristic curves of yellow, magenta and cyan of the silver halide photographic material, 1) the maximum density is not less than 3.0 and the density obtained by subtracting the density of the support from the minimum density is not more than 0.1, 2) the average value of point gamma at various points in the exposure region corresponding to a density value of from not less than 0.5 to less than 1.5 is from not less than 0.85 to not more than 1.15 and the fluctuation width thereof is within .+-.15% of the average value of point gamma in the exposure region, and 3) the average value of point gamma at various points in the exposure region corresponding to a density value of from not less than 1.5 to that 0.3 less than the maximum density is from not less than 1.0 to not more than 1.6 and the fluctuation width thereof is within .+-.15% of the average value of point gamma in the exposure region. The silver halide color photographic material exhibits an excellent tone and color reproducibility with respect to an original.
