ABSTRACT:
A silver halide photographic material is disclosed, said material having silver halide emulsion layers on a support, the emulsion in said silver halide emulsion layers containing magenta coupler represented by the following formula (I), said emulsion containing silver halide grains which have a (110) plane and/or a crystal plane having an edge running through substantially the center of a (110) plane, the silver halide composition of said grains being substantially made of silver bromide and/or silver iodobromide: ##STR1## where Z represents a group of the non-metallic atoms necessary for forming a nitrogen-containing hetero ring which may have a substituent; X is a hydrogen atom or a substituent which is capable of being eliminated upon reaction with the oxidation product of a color developing agent; and R is a hydrogen atom or a substituent.
