Silver halide photographic emulsions prepared and sensitized in the presence of sulfodihydroxy aryl compounds

A method comprising forming a tabular silver bromoiodide emulsion, washing said emulsion, and sensitizing said emulsion by adding dyes and chemical sensitizers, and heating, wherein a sulfodihydroxy aryl compound is added to said emulsion during forming or sensitizing and said sulfodihydroxy aryl compound comprises a sulfodihydroxy aryl compound represented by the Formula I or Formula II ##STR7## wherein X and Y represent an SO.sub.3 group or a hydrogen atom with at least one of X and Y being a sulfo group, wherein said sulfodihydroxy aryl compound is added during forming said emulsion and is not added to a silver nitrate stream, wherein said dyes and sulfodihydroxy aryl compound are on the surface of said grains and said sensitizing dyes comprise carboxy or carbamoyl substituents.

An emulsion comprising tabular silver bromoiodide grains said grains comprising sensitizing dyes and adsorbed onto said grains during grain forming or sensitizing at least one sulfodihydroxy aryl compound represented by the Formula I or Formula II ##STR9## wherein X and Y represent an SO.sub.3 group or a hydrogen atom with at least one of X and Y being a sulfo group wherein said dyes and sulfodihydroxy aryl compound are on the surface of said grains and said sensitizing dyes comprise ##STR10##
