ABSTRACT:
A color photographic silver halide light-sensitive material is described. The material contains a 5-pyrazolone magenta coupler represented by the general formula (I): ##STR1## (all the symbols are as defined in the appended claims). The compounds of the general formula (I) are novel couplers, and are chemically very stable and are particularly superior in two equivalency, sensitivity, and color density.
