ABSTRACT:
A silver halide photographic material comprising a support having thereon at least one hydrophilic colloid layer containing at least one cyan coupler forming coupler represented by the general formula (I) and at least one compound represented by the general formulas (II) or (III): ##STR1## wherein R.sub.1 represents an aliphatic group, an aromatic group, a heterocyclic group, an aromatic amino group or a heterocyclic amino group; R.sub.2, R.sub.4 and R.sub.5 each represents an aliphatic group, an aromatic group or a heterocyclic group; R.sub.3 represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group, an acylamino group, an aliphatic oxy group or an aromatic oxy group; R.sub.2 and R.sub.3 may combine with each other to form a 5-membered, 6-membered or 7-membered ring; Z represents a hydrogen atom or a group or atom which releases upon coupling with a developing agent; L.sub.1 and L.sub.2 each represents a divalent, trivalent or tetravalent aliphatic group; n and m each represents an integer from 2 to 4; each of R.sub.4 and R.sub.5 may be the same or different; and with the proviso that L.sub.2 is not an unsubstituted cyclohexylene group when m is 2.
The silver halide photographic material provides color photographs in which color images have excellent fastness to light and heat and cyan coloration in white background areas is not observed with the lapse of time.
