Abstract

Silver bromoiodide photographic emulsions were precipitated using water-soluble aryl disulfides. The emulsions studied were sub-micron regular (nontabular) crystals containing less than 5% iodide, precipitated with ammonia and/or thioether. When compared to their para-substituted counterparts, water-soluble ortho-substituted aryl disulfides provided improved monodispersity along with no observed formation of large tabular grains. A proposed mechanism for the decreased ripening effect of the ortho-substituted isomer involved an in situ reduction of the disulfide to a ring-closed species that did not interact with silver ion.
