Abstract
Useful scavengers for oxidized developing agents in photographic elements are 2,4-disulfonamidophenols, or alkali labile precursors of such phenols.
Claims15
In a photographic element comprising a support and at least one silver halide emulsion layer, the element containing a scavenger for oxidized developing agent which does not form a dye or release a photographically useful group upon reaction with said oxidized developing agent, the improvement wherein the scavenger is a 2,4-disulfonamidophenol or an alkali labile precursor of such a phenol.
In a photographic element comprising a support, at least two silver halide emulsion layers containing dye-forming couplers and a scavenger for oxidized developing agent which does not form a dye or release a photographically useful group upon reaction with said oxidized developing agent, the improvement wherein the scavenger is a 2,4-disulfonamidophenol or an alkali labile precursor of such a phenol.
