Abstract
There is disclosed a silver halide color photographic material which comprises in a blue-sensitive silver halide emulsion layer acylacetamide yellow dye-forming couplers represented by the following formula (I) and in a red-sensitive silver halide emulsion layer cyan dye-forming couplers represented by the following formula (II) or (III): ##STR1## wherein R.sub.1 represents a monovalent group, Q represents a group of non-metallic atoms required to form together with the C a substituted or unsubstituted 3- to 5-membered cyclic hydrocarbon group or a substituted or unsubstituted 3- to 5-membered heterocyclic group having therein at least one heteroatom selected from a group consisting of N, O, S, and P, and Y.sub.R represents a residue remaining after removing the acyl group from the acylacetamide yellow dye-forming coupler, provided that R.sub.1 is not a hydrogen atom and does not bond to Q to form a ring, ##STR2## wherein R.sup.1 represents --CONR.sup.4 R.sup.5, --SO.sub.2 NR.sup.4 R.sup.5, --NHCOR.sup.4, --NHCOOR.sup.6, --NHSO.sub.2 R.sup.6, --NHCONR.sup.4 R.sup.5, or --NHSO.sub.2 NR.sup.4 R.sup.5 ; R.sup.2 represents a group substitutable on a naphthalene ring; k is an integer of 0 to 3; R.sup.3 represents a substituent, X.sup.1 represents a hydrogen atom or a coupling split-off group; R.sup.4 and R.sup.5, which may be the same or different, each independently represent a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group; R.sup.6 represents an alkyl group, an aryl group, or a heterocyclic group; when k is 2 or more, the R.sup.2 groups may be the same or different and may bond together to form a ring; and the compound may form a dimer or higher polymer formed by bonding through a divalent group or higher polyvalent group at R.sup.1, R.sup.2, R.sup.3, or X.sup.1, ##STR3## wherein R.sup.21 represents an alkyl group, an aryl group, or a heterocyclic group, R.sup.22 represents an aryl group, and Z.sup.1 represents a hydrogen atom or a coupling split-off group.
