Silver halide photographic material

A silver halide photographic material comprising a support having thereon a layer which contains at least one compound represented by general formula (I) or general formula (II):

• Z--R--Se--R'--Z.sub.1 (I)
• Z--R--Se--R" (II)
• where
• R and R' are each independently represented by general formula (III):
• (*)--(R.sub.1 --X.sub.1 --).sub.n --R.sub.2 -- (III)
• where
• * represents the bonding to the selenium atom of the general formula (I) or the general formula (II);
• where
• R.sub.1 and R.sub.2 each independently represent a straight chain or branched chain alkylene group, a cycloalkylene group, a straight chain or branched alkenylene group, a straight chain or branched aralkylene group, or an arylene group, and
• X.sub.1 represents --O--, --S--, --Se--, ##STR16## R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9 represent substituted or unsubstituted alkyl groups, substituted or unsubstituted aryl groups, substituted or unsubstituted alkenyl groups, or substituted or unsubstituted aralkyl groups, and
• n represents an integer 0, 1, 2, or 3;
• Z and Z' each individually represent a hydroxyl group, an amino group, an ammonium group, a carboxylic acid group, a salt of a carboxylic acid group, a sulfonic acid group, a salt of sulfonic acid group, an ether group, a thioether group, a selenoether group, a ureido group, thioureido group, an oxycarbonylamino group, an acyl group, a sulfonyl group, a sulfonamido group, an acyloxy group, a sulfonyloxy group, an oxycarbonyl group, an oxysulfonyl group, or heterocyclic group;
• and
• R" represents an alkyl group, a cycloalkyl group, an alkenyl group, an aralkyl group, or an aryl group.
