Abstract

Disclosed is a light-sensitive silver halide photographic material comprising at least one silver halide emulsion layer on at least one side of a support and at least auxiliary layer adjacent to the silver halide emulsion layer, the silver halide emulsion layer containing a surface latent type silver halide emulsion and a silver halide emulsion having fog internally of the grains, and the auxiliary layer containing a compound represented by the formula (I) shown below:

RfSO.sub.3 M                                               Formula (I)

wherein Rf is a substituted or unsubstituted alkyl group or a substituted or unsubstituted aralkyl group, containing at least 3 fluorine atoms, and M represents hydrogen atom, an alkali metal or ammonium group.

According to the present invention, a light-sensitive silver halide photographic material improved in antistatic performance and also improved in storability without accomplaniment of lowering in sensitivity, which can give images with sensitivity, high contrast as well as high covering power is provided.
