Definitions

  • This invention relates to color photography and particularly to coupler compounds for use in photographic processes.
  • Color-forming compounds which react with the development product of aromatic amino develop- .ing agents to form colored images upon photographic development are well known. Generally, these color-forming compounds or couplers are colorless or substantially colorless. This lack of color is usually desirable where the coupler is'to be incorporated in the emulsion layer and the unused coupler remains after formation of the colcred image. When the coupler is used in the developing solution, it may be colored without detriment to the final image, and some colored couplers are known, such as paraphenylazoacetoacetanilide which was disclosed in 5Mannes and Godowsky Patent 2,108,602.
  • the new couplers are, in themselves, more or less strongly colored, and during the coupling reaction, the chromophore system in the coupler is broken up with the result that the original color of the coupler is destroyed and a new dye is formed.
  • the coupler color is destroyed, and a new color is formed by the coupling reaction, at those points where development occurs. There is formed in this way a dye image of one color on a background of another color.
  • an object of the present invention to provide a colored coupler whose chromophore system is destroyed on coupling.
  • a further object is to provide a novel radical-replacement type of chemical reaction.
  • a still further object is to provide color couplers suitable for color correction processes of color phtography.
  • H j' R. is an alkyl, aryl or a heterocyclic group
  • R is a substituted or unsubstituted aromatic or heterocycllc radical.
  • the structure may be that of a hydrazone or some other tautomeric form or a mixture of these as indicated" by the following structures:
  • the compounds When incorporated in the emulsion layer, the compounds may be added directly to the silver halide emulsion as the sodium or other Water-soluble salt, or they may be incorporated in a coupler solvent as described in Mannes and Godowsky U. S. Patent 2,304,940 or Jelley and Vittum U. S. Patent 2,322,027.
  • the compounds employed according to our invention may be produced by any suitable method, such as by reaction of the reactive methylene compound with the appropriate diazonium compound.
  • compound No. 2 was prepared as follows;
  • Our compounds are particularly useful in a process such as that of Hanson U. S. application Serial No. 538,910 filed May 33, 1944, now Patent No. 2,449,966, September 21, 1948.
  • the Hanson process involves a color correction method in which a colored coupler is incorporated in the photographic emulsion layer prior to exposure and upon development is converted into a colored image where the layer was exposed.
  • the coupler remaining in the unexposed portions of the layer retains its original color, and by suitable choice of the color of the originalcoupler and the color of the final dye image, a masking or correction effect can be obtained.
  • the primary aromatic amino developing agents are generally suitable including the phenylenedia mines and the aminophenols;
  • the alkyl phenylenediamines may be substituted in the amino group as well as in the ring.
  • Suitable compounds are diethyl paraphenylenediamine, monomethyl paraphenylene-diamine, dimethyl paraphenylenediamine and paraaminophenol. These compounds are usually employed in the salt form, such as the hydrochloride or the sulphate, which are more stable than the free amines. All of these compounds have a primary amino group which enables the oxidation product of the developer to couple with the color-forming compounds to form dye images.
  • the following developing solution is suitable for developing gelatino silver halide layers containing colored couplers according to our invention.
  • OHN NR where X and Y are negative groups selected from the class consisting of COR, -COOR,
  • R. is selected from the class consisting of alkyl, aryl, and heterocyclic groups and R is selected from the class consisting of aromatic and heterocyclic radicals and said coupler compound contains no other reactive CH group, and at the place of the silver image formed by the development, splittingsaid coupler compound at the azo linkage and coupling said coupler compound where the splitting occurs, with the development product of the primary aromatic amino developing agent.
  • ⁇ CH-N N-R'
  • X and Y are negative groups selected from the class consisting of -COR, --COOR,
  • -COCOR, -COCOOR, -CONI]IR., -C6H4NO2 and CN R is selected from the class consisting of alkyl, aryl, and heterocyclic groups and R is an aromatic radical of the benzene series and said coupler compound contains no other reactive CH group, and at the place of the silver image formed by the development, splitting said coupler compound at the azo linkage and coupling said coupler compound where the splitting occurs, with the development product of the primary aromatic amino developing agent.
  • X and Y are negative groups selected from the class consisting of COR, -COOR,
  • R is selected from the class consisting of alkyl, aryl and heterocyclic and R is selected from the class consisting of aromatic and heterocyclic radicals and said coupler compound contains no other reactive CH group, exposing said layer and developing it with a primary aromatic amino developing agent, thereby splitting off the --N:N-R group in said coupler compound and coupling said compound at the point of splitting with the oxidation product of the primary aromatic amino developing agent to form a dye image, leaving said coupler compound intact in the re gions of said layer undeveloped by said. developing agent.
