摘要：
A silver halide photographic material comprises a silver halide emulsion layer provided on a support. The silver halide emulsion layer contains a selenium compound represented by the formula (I), (IIa) or (IIb): ##STR1## in which each of R.sup.11 and R.sup.12 is hydrogen, an aliphatic group, an aromatic group, a heterocyclic group, --OR.sup.13 or --NR.sup.14 R.sup.15 ; each of R.sup.21 and R.sup.31 is an aliphatic group, an aromatic group, a heterocyclic group, --OR.sup.23 or --NR.sup.24 R.sup.25 ; each of R.sup.22 and R.sup.32 is an aliphatic group, an aromatic group or a heterocyclic group; each of R.sup.13, R.sup.14, R.sup.15, R.sup.23, R.sup.24 and R.sup.25 is hydrogen, an aliphatic group, an aromatic group or a heterocyclic group; and Ch is S, Se or Te.
