    摘要: The present invention provides a photographic silver halide emulsion containing at least two grain surface modifiers. The grain surface modifiers comprise a transition metal complex containing a transition metal chosen from Groups V to X, inclusive, of the periodic table and a nitrosyl or thionitrosyl ligand; and a transition metal selected from Group VIII of the periodic table.

    摘要: The present invention provides a photographic emulsion comprising silver halide grains, a dopant, and a grain surface modifier. The dopant is a transition metal selected from Group VIII of the periodic table. The grain surface modifier is characterized in that it comprises a transition metal complex having nitrosyl or thionitrosyl ligands with a transition metal selected from Groups V to X of the periodic table.
