ABSTRACT:
The present invention provides a photographic emulsion comprising comprising silver halide grains, an iridium containing hexacoordination complex, and at least two grain surface modifiers, wherein the first of the grain surface modifiers is a transition metal complex comprising a nitrosyl or thionitrosyl ligand with a transition metal selected from the Groups 5 to 10, inclusive, of the periodic table, and the second of the grain surface modifiers is a transition metal complex comprising a transition metal, other than iridium, which is selected from Groups 7 to 10, inclusive, of the periodic table.
