ABSTRACT:
Disclosed is a silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, which contains a fluorine compound having two or more fluorinated alkyl groups having two or more carbon atoms and 11 or less fluorine atoms and having at least one of an anionic hydrophilic group and a nonionic hydrophilic group, 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. There is provided a silver halide photographic light-sensitive material that provides high sensitivity, high contrast, favorable half tone dot quality and superior storage stability.
