ABSTRACT:
Photosensitive substituted-halide silver halide emulsions are prepared by substituting bromide and/or iodide anions for part of the chloride anions of a silver iodochloride emulsion. These substituted-halide silver halide emulsions are particularly useful as negative working silver halide emulsions in diffusion transfer processes.
