Abstract
A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein said emulsion contains as a dopant a metal complex represented by the following formula (I) or (II): [MLXLI(4−x)]n (I) wherein M represents a metal or a metal ion, L represents an imidazole compound which is bonded to M, x represents 1, 2, 3 or 4, n represents an integer of from −6 to +5, and LI represents a chemical species bonded to M and LI(4−x) may be the same or different chemical species when x is 1 or 2; [MXnL(6−n)]m (II) wherein M represents a metal ion, L represents an imidazole compound, X represents a halogen ion, n represents 3, 4 or 5, and m represents −5, −4, −3, −2, −1, 0, +1 or +2.
Claims10
