Silver halide photographic light-sensitive material

A silver halide photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, which contains at least one compound represented by the following formula (A-1):

• {B1—Au(I)—B2}Xn (A-1)
• wherein B1 represents an azole compound which is linked to the Au via a nitrogen atom thereof and B2 is selected from the group consisting of an azole compound, a compound containing at least one of a labile sulfur group, a labile selenium group, and a labile tellurium group each capable of reacting with silver halide to produce silver sulfide, silver selenide or silver telluride, a hydantoin compound, a phosphine compound, a halogen atom, a thioether compound, a mesoionic compound and R1—S, R1 represents an aliphatic hydrocarbon group, an aryl group, a heterocyclic group, an acyl group or a sulfonyl group, X represents a counter anion or cation necessary for neutralizing the electric charge of the compound, and n represents a number of from 0 to 1.

A silver halide emulsion chemically sensitized with at least one compound represented by formula (1):

• {L1—A1—Y1—Au(I)—Y2—A2—L2}Xn (1)
• wherein L1 and L2, which may be the same or different, each represents a group containing a labile sulfur group, labile selenium group or labile tellurium group capable of reacting with silver halide to produce silver sulfide, silver selenide or silver telluride, Y1 and Y2, which may be the same or different, each represents a coordination group capable of forming a complex with gold, A1 and A2, which may be the same or different, each represents a divalent linking group or a mere bond, X represents a counter salt necessary for neutralizing the electric charge of the compound, and n represents a number of from 0 to 1.
