Abstract

A silver halide photographic material comprising a support having provided thereon at least a silver halide emulsion layer, wherein the material contains at least one metal complex contained in any of groups A, B and C: group A: an optically active metal complex; group B: a metal complex comprising a metal ion selected from the group consisting of transition metallic elements belonging to period 4 to 6 and group III to XI of the Periodic Table, and typical metallic elements belonging to period 4 to 6 and group XII to XIV of the Periodic Table, and at least one ligand represented by the following formula (I): wherein Z represents an atomic group to form a 5- or 6-membered ring; A represents a carbon atom or a nitrogen atom; X represents O31, S31 , NR1R2 or COO−; R1 and R2 each represents a hydrogen atom or an alkyl group; R represents a substituent; and n represents 0 or an integer of from 1 to 6; group C: a metal complex selected from a porphyrin complex, a porphycene complex, a phthalocyanine complex, a chlorin complex, and a bacteriochlorin complex.

  1. 1. A silver halide photographic material comprising a support having provided thereon at least a silver halide emulsion layer containing silver halide grains, wherein said silver halide grains are doped with at least one metal complex containing in any of groups A, B and C: group A: an optically active metal complex; group B: a metal complex comprising a metal ion selected from the group consisting of transition metallic elements belonging to period 4 to 6 and group III to XI of the Periodic Table, and typical metallic elements belonging to period 4 to 6 and group XII to XIV of the Periodic Table, and at least one ligand represented by the following formula (I): wherein Z represents an atomic group to form a 5- or 6-membered ring; A represents a carbon atom or a nitrogen atom; X represents O−, S−, NR1R2 or COO—; R1 and R2 each represents a hydrogen atom or an alkyl group; R represents a substituent; and n represents an integer of from 0 to 6; group C: a metal complex selected from the group consisting of a porphyrin complex, a porphycene complex, a phthalocyanine complex, a chlorin complex, and a bacteriochlorin complex.
  2. 14. A silver halide photographic material comprising a support having provided thereon at least a silver halide emulsion layer, wherein the material contains at least one metal complex containing in any of groups A, B and C: group A: an optically active metal complex; group B: a metal complex comprising a metal ion selected from the group consisting of transition metallic elements belonging to period 4 to 6 and group III to XI of the Periodic Table, and typical metallic elements belonging to period 4 to 6 and group XII to XIV of the Periodic Table, and at least one ligand represented by the following formula (I): wherein Z represents an atomic group to form a 5- or 6-membered ring; A represents a carbon atom or a nitrogen atom; X represents O−, S−, NR1R2 or COO−; R1 and R2 each represents a hydrogen atom or an alkyl group; R represents a substituent; and n represents an integer of from 0 to 6; group C: a metal complex selected from the group consisting of a porphyrin complex, a porphycene complex, a chlorin complex, and a bacteriochlorin complex.
