Definitions

  • This invention pertains to a new class of yellow dye- forming couplers and to silver halide color photographic light-sensitive elements, emulsions and processes comprising such couplers. More specifically, the invention pertains to a new class of yellow couplers having a multicyclic carbon center attached to the 2- position of a substituted phenyl carbamoyl acetyl group and a coupling-off group having a hydrophilic functional group.
  • yellow dye-forming couplers are open chain ketomethylene compounds which yield azomethine dyes upon coupling with an oxidized developer.
  • the most common yellow couplers are acylacetanilides, such as pivaloylacetanilides and benzoylacetanilides.
  • Pivaloylacetanilide yellow couplers which are frequently used in the art have, in general, low coupling efficiencies due to their high pK a values.
  • benzoylacetanilide couplers have been proposed and employed in the art.
  • benzoylacetanilide yellow couplers yield image dyes with very poor light stability.
  • the disclosed couplers were characterized by improved light fastness over the corresponding pivaloylacetanilides. Nevertheless, the adamantoylacetanalide yellow couplers are characterized by unsatisfactory coupling efficiency.
  • 2-equivalent yellow couplers containing a substituent in the coupling position are disclosed and employed in the art.
  • a coupling-off group COG

  • the aryloxy coupling-off group has at least one substituent which is an ionizable group or a solubilizing group.
  • ionizable substituent denotes a substituent which contains at least one acidic hydrogen that ionizes substantially at the processing pH of the color developer.
