Claims12
A color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing at least one each of cyan color image forming couplers represented by the following general formulae (I) and (II):
- ##STR15## wherein:
- R.sup.1, R.sup.2 and R.sup.4, which may be the same or different, each represents an aliphatic hydrocarbon group, a substituted aliphatic hydrocarbon group, an aryl group, a substituted aryl group, a heterocyclic group or a substituted heterocyclic group;
- R.sup.3 and R.sup.5, which may be the same or different, each represents a hydrogen atom, a halogen atom, an alkyl group or an acylamino group, or R.sup.3 represents a non-metallic atomic group necessary for forming a nitrogen-containing 5- or 6-membered ring together with R.sup.2 ;
- R.sup.6 represents a normal alkyl group having 1 to 14 carbon atoms;
- R.sup.7 and R.sup.8 each represent a hydrogen atom;
- Z.sup.1 and Z.sup.2, which may be the same or different, each represents a hydrogen atom or a group capable of being eliminated by a coupling reaction with an oxidation product of a developing agent;
- n represents 0 or 1;
- and
- further wherein said emulsion layer contains at least one compound represented by general formula (III) or (IV):
- ##STR16## wherein:
- R.sup.9, R.sup.10, R.sup.11 and R.sup.12, which may be the same or different, each represents a hydrogen atom, a halogen atom, a nitro group, a cyano group, an alkyl group, a substituted alkyl group, an alkoxy group, an aryl group, an aryloxy group, an acylamino group or an alkoxycarbonyl group;
- R.sup.13 and R.sup.14, which may be the same or different, each represents a hydrogen atom, an alkyl group or a substituted alkyl group, provided that R.sup.13 and R.sup.14 do not both represent a hydrogen atom;
- and
- R.sup.15 represents an m-valent organic group, with m being an integer of 1 to 4, and
- wherein said compound represented by general formula (III) is additionally present in at least one layer adjacent to said emulsion layer.
