Abstract
A silver halide emulsion including silver halide grains and a binder and satisfying Requirement (1) of 0<B/A<0.2, wherein A ((mol %) is an iridium content at a surface of the silver halide grains, and B (mol %) is an average iridium content at a subsurface of the silver halide grains.
Claims12
A silver halide emulsion comprising silver halide and satisfying Requirement (1):
- 0<B/A<0.2 Requirement (1)
- wherein A (mol %) is an iridium content at a surface of the silver halide grains, and B (mol %) is an average iridium content at a subsurface of the silver halide grains.
A silver halide emulsion comprising silver halide grains and a binder and satisfying Requirement (2):
- 0<B/C<0.7 Requirement (2)
- wherein C (mol %) is an iridium content at a maximum point of the iridium content in an interior of the silver halide grains, and B (mol %) is the average iridium content at the subsurface of the silver halide grains.
A silver halide emulsion comprising silver halide grains and a binder and satisfying Requirement (3):
- 0<C/A<0.5 Requirement (3)
- wherein C (mol %) is the iridium content at the maximum point of the Ir content in the interior of the silver halide grains, and A (mol %) is the iridium content at the surface of the silver halide grains.
