Abstract
A ballasted amine is incorporated in a silver halide photographic element which contains a 2,4-disulfonamidophenol which functions as a scavenger for oxidized developing agent. The 2,4-disulfonamidophenol serves to avoid color contamination while the ballasted amine serves to reduce dye stain.
Claims20
A photographic element comprising at least one red-sensitive silver halide emulsion layer containing a sensitizing dye, said element comprising a 2,4-disulfonamidophenol, or an alkali labile precursor thereof, which acts as a scavenger for oxidized developing agent and a ballasted amine which serves to reduce dye stain caused by said sensitizing dye;
- said ballasted amine having a pKa greater than 4.5 and a partition coefficient of at least 5.0.
