摘要： A silver halide photographic light-sensitive material containing a 1H-pyrazolo[3,2-c]-s-triazole type magenta coupler is disclosed. The magenta coupler has an --SO.sub.2 -- group and at least one group selected from the group consisting of a --COOM group and a --SO.sub.3 M group, M being a hydrogen atom or a cation, in its molecule. The photographic material is improved in color development performance and preservability of magenta images.
