Silver halide photographic light sensitive material

摘要

Disclosed is a silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, which contains a compound of which one-electron oxidized derivative produced by one electron oxidation of the compound is capable of releasing two or more electrons with a bond cleavage and 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 5.0 or more for the optical density range of 0.3-3.0. This silver halide photographic light-sensitive material shows high contrast and high sensitivity.
