A silver halide photographic light-sensitive material comprising negative type silver halide grains of core-shell structure with an inner core of silver bromide or iodobromide, an outermost shell containing 0 to 10 mol % of silver iodide, a high iodide-containing shell provided inside said outermost shell and an intermediate shell of which a silver iodide content is at least 3 mol % higher than that of said outermost shell, and at least 3 mol % lower than than of said highly iodide-containing shell, the material also comprising a magenta coupler of formula
wherein Z forms a nitrogen-containing heterocyclic ring optionally substituted, X represents hydrogen, halogen or monovalent group which is capable of being released from the coupler residue and R represents a hydrogen atom, a halogen atom or a monovalent group.
