  • Phenylsulfamoyl couplers, coupler compositions and photographic elements suited to forming integral sound tracks
    Patent number: 4250251
    Abstract: Ballasted primary and secondary 3'-sulfamoyl-1-hydroxy-2-naphthanilide couplers are disclosed as well as compositions and photographic elements containing these couplers in coupler solvent particles. The coupler solvent particles are comprised of a combination of a coupler solvent and the coupler capable of permitting the formation of a microcrystalline dye. Surprisingly these microcrystalline dyes exhibit a broadened absorption characteristic in the 750 to 850 nm region of the spectrum. Dye images having such absorption characteristics are particularly suited to forming integral infrared absorbing sound tracks in photographic elements, such as motion picture projection films.
    Type: Grant
    Filed: July 11, 1979
    Date of Patent: February 10, 1981
    Assignee: Eastman Kodak Company
    Inventors: Harland J. Osborn, Robert G. Cameron, Edward J. Walsh
  • 2,5-Dicarbonylaminophenol dye-forming couplers
    Patent number: 4124396
    Abstract: 2,5-Dicarbonylaminophenols containing a p-alkyl-sulfonylaminophenoxy terminal moiety or a p-alkylamino-sulfonylphenoxy terminal moiety in the five-position substituent of the molecule are color-forming couplers useful in photographic silver halide emulsions and elements.
    Type: Grant
    Filed: March 3, 1977
    Date of Patent: November 7, 1978
    Assignee: Eastman Kodak Company
    Inventor: Harland J. Osborn
  • Phenolic dye-forming couplers
