ABSTRACT:
A color photographic light-sensitive material having a silver halide emulsion layer containing a 1-phenyl-2-pyrazol-5-one magenta color-forming coupler, in which the 1-phenyl group of the coupler is substituted (1) with a R.sub.1 OOC-group, wherein R.sub.1 represents a group having about 8 to 26 carbon atoms, or (2) with a R.sub.2 OOC-group and a R.sub.3 OOC-group, wherein R.sub.2 and R.sub.3, which may be the same or different, each represents a group having about 4 to 18 carbon atoms; and in which the 3-position of the pyrazolone is substituted with an acylamino group, an ureido group, an alkoxy group, an amino group or an anilino group. The color photographic light-sensitive material provides stable magenta dye images having good spectral absorption characteristics.
