ABSTRACT:
A novel silver halide color photographic material is provided which comprises at least one colored coupler represented by the general formula (I) and at least one cyan coupler represented by the general formula (II), (III), (IV) or (V): ##STR1## wherein R.sub.1 represents an aromatic or heterocyclic group; R.sub.2 represents a group capable of being substituted on a naphthol ring; R.sub.3 represents an aliphatic, heterocyclic or aromatic group; R.sub.4 represents an aromatic group excluding p-cyanophenyl group; R.sub.5 represents an aromatic or heterocyclic group; R.sub.6 represents an aliphatic group; n represents an integer of 0 to 4; m represents an integer of 0 to 3; A--B--N.dbd.N--D represents a group which is eliminated upon coupling; A represents a divalent group whose bond to the carbon atom at the coupling active position of the coupler is cleaved upon the reaction with an oxidation product of a color developing agent; B represents a divalent aromatic or heterocyclic group; D represents an aromatic or heterocyclic group; Y represents a hydrogen atom or a group which is eliminated upon coupling; and X represents --O--, --S-- or ##STR2## in which R.sub.7 represents a hydrogen atom or an organic substituent group, with the proviso that when n and m each represents a plural integer, R.sub.2 may be the same as or different from each other or may be bonded to each other to form a ring. In the general formula (V), R.sub.2 and X or X and Y may be bonded to each other to form a ring. R.sub.1, R.sub.2, R.sub.3, R.sub.5, R.sub.6, R.sub.7, X or Y may form a dimer or higher polymer. In the general formula (I), at least one of the groups represented by A, B and D has sulfo groups, carboxyl groups, or alkali metal or ammonium salts thereof as substituent groups.
