Color photographic element containing improved polymeric disulfonamidophenol for scavenging oxidized developer
摘要:
This invention relates to a photographic element comprising a support, a radiation sensitive silver halide emulsion layer and a water dispersible polymeric disulfonamidophenol that is substantially immobile in the element. The invention provides color photographic elements that exhibit improved stability, color reproduction and robustness in terms of processing variations; particularly variations in red density due to sensitizing dye.
