ABSTRACT:
In a silver halide photographic light-sensitive material having at least one silver halide emulsion layer on a support, light-sensitive silver halide grains contained in the silver halide emulsion layer have been subjected to selenium sensitization, and the silver halide emulsion layer or another hydrophilic colloid layer which is in a water-permeable relationship with the silver halide emulsion layer contains at least one compound represented by formula (I) (wherein Z represents a heterocyclic ring directly or indirectly having at least one substituent group selected from the group consisting of --SO.sub.3 M, --COOR.sub.1, --OH, and --NHR.sub.2, M represents hydrogen, alkali metal, quaternary ammonium, or quaternary phosphonium, R.sub.1 represents hydrogen, alkali metal, or alkyl having 1 to 6 carbon atoms, R.sub.2 represents hydrogen, alkyl having 1 to 6 carbon atoms, --COR.sub.3, --COOR.sub.3, or --SO.sub.2 R.sub.3, and R.sub.3 represents hydrogen, aliphatic, or aromatic): ##STR1##
