Abstract (en)
A silver halide photographic emulsion contains tabular silver halide grains consisting of silver chloroiodobromide, silver iodobromide, silver chlorobromide, or silver bromide, having an aspect ratio of 3 or more and at least one dislocation line per grain, and chemically sensitized by at least one selenium sensitizer, at least one gold sensitizer, and at least one sulfur sensitizer. A photographic light-sensitive material comprises at least one silver halide emulsion layer on a support, wherein tabular silver halide grains described above account for at least 50% of a total projected area of silver halide grains in the silver halide emulsion layer.
