IM-0008 TITLE SILVER HALIDE EMULSION WITH IMPROVED SPEED Photographic, silver halide emulsions can be additionally sensitized without a deleterious increase in fog, by the addition of an alkali metal salt of 1napthol-4-sulfonic acid. These emulsions are stable, and have good contrast and top density. The 1napthol-4-sulfonic acid can be added conveniently from an aqueous solution and is totally compatible with conventional silver halide elements.
