ABSTRACT:
Photographic emulsions and elements are disclosed containing composite silver halide crystals. The composite crystals are comprised of multi-faceted, radiation-receptive silver iodide crystals having a minimum mean diameter of at least 0.1 micron and silver chloride crystals forming epitaxial junctions with the silver iodide crystals. At least half of the facets of the silver iodide crystals are substantially free of epitaxial silver chloride. The silver chlorides are limited to less than 75 mole percent, based on the total silver halide forming the composite crystals.
