Patent ID: 7279272

Claim:
A silver halide emulsion comprising silver halide particles, wherein a content of silver chloride in the silver halide particles is at least 89 mol %, and wherein the silver halide particles comprising at least one of (i) at least one phase selected from the group consisting of a laminar phase comprising silver bromide and a six-coordinate complex in which all of six ligands are made of Cl, Br or I and Ir is a central metal, and having a maximum point where a silver bromide content ratio is at a maximum value, which maximum point is inside the silver halide particles, and a content of the silver bromide in the surroundings of the maximum point decreases in a direction from the maximum point toward the surface of the silver halide particles and the direction from the maximum point toward the inside of the silver halide particles, and a laminar phase comprising silver iodide and a six-coordinate complex having H 2 O, OH, O, OCN, thiazole or substituted thiazole as a ligand and containing Ir as a central metal, and (ii) a phase comprising silver iodide and a phase comprising silver bromide, which phase comprising silver bromide is disposed further inside of the silver halide particles than the phase comprising silver iodide, wherein the phase (ii) satisfies either of the conditions wherein the phase comprising silver bromide is a laminar phase having a maximum point where a silver bromide content ratio is at a maximum value, which maximum point is inside the silver halide particles, and a content of the silver bromide in the surroundings of the maximum point decreases in a direction from the maximum point toward the surface of the silver halide particles and the direction from the maximum point toward the inside of the silver halide particles, or at least one of the phase comprising silver iodide and the phase comprising silver bromide comprises a six-coordinate complex having H 2 O, OH, O, OCN, thiazole or substituted thiazole as a ligand and containing Ir as a central metal.
