Abstract:
A spectrally and chemically sensitized silver halide emulsion, which comprises silver halide grains, wherein 50% or more of the total projected area of the silver halide grains is provided by tabular grains having {111} planes as principal planes and having an aspect ratio of 2.0 or more, and said tabular grains contain silver iodobromochloride grains or silver bromochloride grains, each having a silver chloride content of 90 mole % or more, wherein all corners of said silver iodobromochloride grains or silver bromochloride grains do not have an intersecting point, which is formed by extending two straight-line portions of the neighboring sides on the principal plane, in the interior of the grain, and the intersecting points are substantially coincident with the actual corners of grains, making the corners angular.
