Abstract

Dyes of the formula: <CHEM> where R1 is halogen, substituted or unsubstituted phenyl, or substituted or unsubstituted styryl, R2 and R3 are each independently substituted alkyl, substituted alkenyl, or substituted aryl that are substituted with an anionic solubilising group, Z represents the atoms necessary to complete a substituted or unsubstituted naphthyl ring, and X<+> is a cation, are disclosed as sensitizing dyes for photographic compositions containing silver halide that is high in silver chloride content, low in silver iodide content, or both.
