Abstract
A silver halide color negative photographic lightsensitive material comprises, on a support, at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one red-sensitive silver halide emulsion layer. The total coating amount of colored couplers in the lightsensitive material is less than 0.05 mMol/m2. The lightsensitive material contains at least one spectrally sensitized silver halide emulsion and a compound capable of absorbing light within the spectrally sensitizing region of the spectrally sensitized silver halide emulsion, and capable of reducing the sensitivity of the spectrally sensitized silver halide emulsion by at least 0.05 LogE.
