Abstract
Disclosed is a silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, wherein 40 mol % or more of silver halide contained in the silver halide emulsion layer is silver bromide and the silver halide contains 1×10 mole or more per mole of silver of a metal complex containing one or more cyanide ligands, and the silver halide photographic light-sensitive material has a characteristic curve drawn in orthogonal coordinates of logarithm of light exposure (x-axis) and optical density (y-axis) using equal unit lengths for the both axes, on which gamma is 4.0 or more for the optical density range of 0.1-1.5. There is provided a silver halide photographic light-sensitive material showing high contrast and high sensitivity.
