Abstract:
A silver halide color photographic material comprises at least one blue-sensitive emulsion layer (BL layer), at least one green-sensitive emulsion layer (GL layer) and at least one red-sensitive emulsion layer (RL layer) on a support. A maximum absorption wavelength of the green-sensitive emulsion layer represented by &lgr;max(G) is in the range of 500 nm≦&lgr;max(G)≦570 nm. The photographic material further has at least one short-wavelength-green-sensitive emulsion layer (CL layer) meeting the following requirements (i) and (ii): (i) a maximum absorption wavelength of the CL layer represented by &lgr;max(C) being in the range of 490 nm≦&lgr;max(C)≦560 nm, and 80 nm≧&lgr;max(G)−&lgr;max(C)≧5 nm, and (ii) the total iodine amount of silver halide grains contained in the CL layer being in the range from 60% to 300% of that contained in the green-sensitive emulsion layer.
