摘要： The invention is generally accomplished by providing a halide emulsion comprising radiation sensitive silver halide doped with a combination of iridium and transition metal complex with a nitrosyl ligand. The method of doping comprises one in which the transition metal complex with a nitrosyl ligand is generally evenly distributed throughout the grain and the iridium is present in about the outer 10 percent, by volume, of said grain. In a preferred form, the transition metal complex with a nitrosyl ligand is present in an amount between about 0.03 and about 36 molar parts per billion, and the iridium is present in an amount of between about 10 and about 350 molar parts per billion.

摘要： Sensitizing dyes for photographic materials are disclosed. The dyes have the formula: ##STR1## Z.sub.1 represents the atoms necessary to complete a benzoxazole nucleus, a benzothiazole nucleus, a benzoselenazole nucleus, a benzotellurazole nucleus, or a benzimidazole nucleus, which, in addition to being substituted by R.sub.3, may be further substituted or unsubstituted,Z.sub.2 represents the atoms necessary to complete a benzoxazole nucleus, a benzothiazole nucleus, a benzoselenazole nucleus, a benzotellurazole nucleus, or a benzimidazole nucleus, which, in addition to being substituted by F, may be further substituted or unsubstituted,R represents H or substituted or unsubstituted alkyl or aryl,R.sub.1 and R.sub.2 each independently represents substituted or unsubstituted alkyl or aryl,R.sub.3 represents an aryl group that may be appended to or fused with Z.sub.1, andX is a counterion as needed to balance the charge of the molecule.
