    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.

    摘要: Compounds containing an aromatic ring portion fused with a tellurazolium or derivative tellurazole, tellurazoline (including tellurazolinylidene), or tellurazolinium ring portion are disclosed together with processes and intermediates for their preparation. With properly selected pendant groups these tellurazolium and derivative compounds can be usefully employed as dyes, antifoggants or stabilizers, nucleating agents, latent image keeping addenda, or speed or contrast altering addends in silver halide photographic systems.

    摘要: A color photographic element which comprises a light sensitive silver halide emulsion layer and a non-light sensitive interlayer containing a ballasted 5-carbamoyl-1,3-dihydroxybenzene compound. The element exhibits an improved ability to prevent oxidized developer from diffusing away from the imaging layer in which it formed and into other color records where it can form the wrong color dye.
