ABSTRACT:
A novel silver halide color photographic material is provided, containing at least one coupler represented by formula (C-I) and at least one compound represented by formula (A-I) or (A-II) ##STR1## wherein Q.sub.1 represents an atomic group containing at least one nitrogen atom required to form a 5- or more membered nitrogen-containing heterocyclic ring together with the carbon atoms to which it is bonded; Z.sub.1 represents a hydrogen atom or a coupling-off group; R.sub.Cl represents an acyl or sulfonyl group; and R.sub.C2 represents a hydrogen atom or a C.sub.1-8 aliphatic group, or the substituents for R.sub.Cl, R.sub.C2, Z.sub.1, or Q.sub.1 form a dimeric or polymeric coupler; ##STR2## wherein R represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, or a hydrolyzable protective group; R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 each represents a hydrogen atom or a substituent; R' represents a hydrogen atom, an aliphatic group, an acyl group, a sulfonyl group, a sulfinyl group, an oxyradical group or a hydroxyl group; A represents a non-metallic atomic group required to form a 5-, 6- or 7-membered ring; and R.sub.6, R.sub.7, R.sub.8, and R.sub.9 each represents a hydrogen atom or an alkyl group, or the substituents represented by R and R.sub.1 or two or R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 in formula (A-I) which are in an ortho-position relation are bonded to each other to form a 5-, 6-, or 7-membered ring, or the substituents represented by R.sub.6 and R.sub.7, R.sub.8 and R.sub.9, or R' and R.sub.6 in formula (A-II) are bonded to each other to form a 5-, 6-, or 7-membered ring.
