发明名称 Epitaxially sensitized tabular grain emulsions containing speed/fog sulfodihydroxy aryl enhancing addenda
摘要 The invention relates to a radiation-sensitive silver halide emulsion comprising silver halide grains including tabular grains (a) having {111} major faces, (b) containing greater than 70 mole percent bromide, based on silver, (c) accounting for greater than 90 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 mu m, (e) exhibiting an average thickness of less than 0.07 mu m, and (f) having latent image forming chemical sensitization sites on the surfaces of the tabular grains, and a spectral sensitizing dye adsorbed to the surfaces of the tabular grains, wherein the surface chemical sensitization sites include at least one silver salt epitaxially located on said tabular grains adsorbed onto said grains during grain forming or sensitizing and said emulsion further comprising at least one sulfodihydroxy aryl compound represented by the Formulas I or II <IMAGE> wherein X and Y represent an SO3 group or a hydrogen with at least one of X and Y being a sulfo group.
