Patent ID: 7229738

Claim:
A silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, which contains a fluorine compound represented by the following formula (A): wherein R 1 and R 2 each represents a fluorinated alkyl group having two or more carbon atoms and 3 to 9 fluorine atoms; R 3 and R 4 each represents a hydrogen atom or a substituted or unsubstituted alkyl group; one of A and B represents a hydrogen atom, and the other represents -L b -SO 3 M where M represents a hydrogen atom or a cation, and L b represents a single bond or a substituted or unsubstituted alkylene group, in at least one layer selected from the group consisting of the emulsion layer, a protective layer on the emulsion layer side and an undercoat layer, 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, wherein the fluorine compound represented by the formula (A) and gelatin exist together.
