Abstract: A radiation-sensitive emulsion is disclosed comprised of cubical silver halide grains containing from 0.05 to 3 mole percent iodide, based on total silver, and an iridium coordination complex dopant, wherein (i) the iodide is incorporated in the grains in a controlled, non-uniform distribution forming a core containing at least 50 percent of total silver, an iodide free surface shell having a thickness of greater than 50 Å, and a sub-surface shell that contains a maximum iodide concentration, and (ii) the iridium coordination complex dopant is incorporated into the sub-surface shell or into a region of the core extending up to 60% of the total silver into the grain from the sub-surface shell. Speed and reciprocity of iodochloride emulsions can be improved by localized addition of known in the art reciprocity-controlling iridium dopants in relation to high iodide region of the grain. By carefully incorporating reciprocity-controlling dopant within a well defined band within a grain the difficulties of the prior art can be overcome.
