摘要:
A photographic naphtholic coupler comprising a ballast free naphtholic coupler moiety containing a --CONH.sub.2 group in the 2- position and a ballasted coupling-off group in the 4- position enables good wash out of dye formed upon oxidative coupling from a photographic material during processing of such a photographic material. Such a naphtholic coupler is useful in photographic silver halide materials and processes.

摘要:
Silver halide color photographic elements having multiple color imaging layers contain a permanent, pre-formed yellow colorant that is present in an amount to provide a status M blue density greater than 0.003 per mg/m2. This colorant provides minimum density at lower cost and can be incorporated with minimal or no organic solvents and thus enable a reduced organic load that may lead to improved film physical properties.

摘要:
A non-infrared sensitized low silver photographic element with a non-light sensitive layer, preferably an antihalation layer, containing a diphenylaminocyclopentene heptacyanine benzothiazolium infrared dye where the benzothiazolium groups have electron-withdrawing substituents on the phenyl ring and solubilzed alkyl groups on the nitrogen. The infrared dye can be present as a liquid-crystalline dispersion. This class of infrared dyes form J-aggregrated species in a liquid-crystalline or a solid particle dispersion with high IR density and low visible absorbance.
