Silver halide photographic material containing selenium compound

摘要

A silver halide photographic material comprises a silver halide emulsion layer and a non-light-sensitive hydrophilic colloidal layer provided on a support. The silver halide emulsion layer or the hydrophilic colloidal layer contains a selenium compound represented by the formula (I), (II) or (III): (* CHEMICAL STRUCTURE *) (I) (* CHEMICAL STRUCTURE *) (II) (* CHEMICAL STRUCTURE *) (III) in which R11 is an aliphatic, aromatic or heterocyclic group, -OR13 or -NR14R15; each of R13, R14 and R15 is hydrogen or an aliphatic or aromatic group; Ch is S, Se or Te; R12 is an aliphatic, aromatic or heterocyclic group or -COR16; each of R16, R21 and R31 has the same meaning as that of R11; M1 is Ge, Sn or Pb; M2 is Ni, Pd or Pt; each of R22 and R32 is an aliphatic or aromatic group; and each of n and m is 1 or 2.
