Silver halide photographic materials and method producing thereof

A silver halide photographic material having at least one light-sensitive silver halide emulsion layer coated on a support, wherein said silver halide emulsion layer contains silver chlorobromide grains containing 90 mol % or more silver chloride, wherein the silver chlorobromide grains comprise cubic or tetradecahedral host silver halide grains with at least one surface region having a higher content of silver bromide at the surface, said host silver halide grains have a halogen composition of silver chlorobromide or silver chloride and said host grains have no silver iodide or less than 2 mol % of silver iodide, and said at least one surface region is located at the vicinity of at least one of the corners of the host grains, wherein the vicinity of the corners is the area within the area of a regular square having a side length of about one-third of the diameter of a circle having the same area as the projected area of a normal crystal silver chlorobromide grain, wherein

• (a) not more than 15 mol % of the average silver bromide content is present at the surface of said silver chlorobromide grains, and
• (b) the silver bromide content of the at least one surface region at the vicinity of the at least one of the corners of said silver chlorobromide grains is less than 60 mol %.
