ABSTRACT:
A color photographic light-sensitive material comprising a support having thereon a green-sensitive silver halide emulsion layer containing a magenta dye forming coupler represented by the following general formula (I) ##STR1## wherein R.sup.4 represents a halogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkoxy group; R.sup.5 represents a hydrogen atom, a halogen atom, a nitro group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group or a substituted or unsubstituted acylamino group; R.sup.6 represents a hydrogen atom, a halogen atom or a mono-valent organic residue; X represents a hydrogen atom or a group capable of being released upon coupling and exhibiting a two-equivalent property; and n represents an integer from 1 to 5 and when n represents 2 or more, R.sup.4 may be the same or different, and a red-sensitive silver halide emulsion layer containing a cyan dye forming coupler represented by the following general formula (II) ##STR2## wherein A represents a cyan coupler residue, but the -NHCO group does not bond to A in the active position of A; R.sup.1 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, R.sup.2 represents hydrogen or a substituted or unsubstituted alkyl group; each R.sup.3 independently represents a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group; and n represents an integer from 1 to 3 and when n represents 2 or more. The color photographic light-sensitive material provides a color image in which the yellow stain at the unexposed area upon irradiation of light is prevented.
