Abstract
A silver halide photographic light-sensitive material is disclosed which is decreased in variation of light-sensitivity caused by a change in environmental humidity and a prolonged storage of the photographic material. The photographic material comprises a support and photographic component layers including at least one silver halide emulsion layer in which the silver halide emulsion layer contains a compound selected from the group of the compounds represented by the following formulas [I], [II], [III], [IV] or [V], and at least one of the photographic component layer is added with inorganic sulfur; ##STR1##
