  • the coupler shows a sutcient solubility in aqueous media and a suitable spectral adsorption for color photography.
  • the presentv invention relates generally to a photograph- .ic sensitivematerial containing a yellow couplerhaving the general formula COOH COCHZCONI-I- t i OR.
  • R is an alkyl group having 8-716 carbon atoms "and R is an alkyl group having 1 4 carbon atoms.
  • Conventional yellow couplers for a subtractive color process are derivatives of lt-keto acid, which have in the molecules at least one carboxyl group or sulfonic acid group as an alkali-soluble group i.e., a group solubilizing the molecule in alkaline media.
  • the alkali-soluble groups of these known derivatives that is, the carboxyl groups or sulfonic acid groups are ones attached to the benzene nucleus of an anilide or the side chain of a benzoyl nucleus, but Vmost o f them are ones attachedto the atomic group of one side of an active methylene group.
  • a coupler which has been usedhitherto has a carboxyl group or carboxyl groups but in the known coupler havatonly one side of the active methylene group, the solubility in an alkali of the coupler cannot be improved remarkably by increasing the number of carboxyl groups. Hence, ⁇ it frequently occurs that the coupler is precipitated when added to an emulsion or even precipitated in an after-treatment step from a photographic sensitive material containing the coupler, which results in reducing markedly the transparency of the image.
  • an object of this invention is to provide a photographic sensitive material containing a yellow coupler having good solubility.
  • Another object of this invention is to provide a color 3,341,331 Patented Sept. 12, 1967 photographic sensitive material having good color reproducing property.
  • a further object of this invention is to provide a color photographic sensitive material which does not have such drawbacks as mentioned above.
  • the coupler employed in this invention contains hydrophilic carboxyl groups in both groups attached to an active methylene group and has very high solubility in an alkali as compared with a conventional coupler containing one or more alkali-soluble groups in only one of the groups attached to the active methylene group. Therefore, the coupler in this invention is not precipitated when it is added in an emulsion or is not precipitated in an after-treatment step, thereby allowing a color image having excellent transparency to be obtained.
  • the absorption spectrum of a pigment shifts always toward the longer wave side of the spectrum when a coupler which contains an electron attractive group such as carboxyl group is used
  • the absorption spectrum of a pigment does not shift toward the longer wave side and the maximum absorption wave length is narrow when the coupler according to this invention is used. Accordingly, the absorption in the green region which adversely affects the color reproduction is very small when the couplers of this invention are employed.
  • the color image obtained from the coupler according to this invention has ⁇ a very excellent durability against the eiect of temperature, humidity and light.
  • Examples of the couplers according to this invention are: l
  • Example 1 200 ml. of an aqueous 5% alkali solution (3.5 ml. of one normal solution -of caustic soda is used per one gramme of coupler) of 5-carboxy-2-methoxy(4-octadecenylsuccinrnonoamido)benzoyl acetanilide (Formula I) is mixed with 1 kg. of a silver halide photographic emulsion and the pH of the solution is adjusted to 7.1-8.0 with caustic soda or citric acid. The mixture is applied on a support such as film, dried, developed with the following developer after exposure, bleached and fixed.
  • a support such as film
  • the yellow image so obtained has its maximum absorption at 440 ma, high transparency and excellent light fastness, and is decolored very little by the effect of temperature and humidity.
  • Example 2 In .place of the coupler of Formula I in Example l, 5 carboxy 2 methoxy (4 tetradecenylsuccinmonoamido)benzoyl acetanilide (Formula II) is used and treated as described in Example l.
  • the yellow image so obtained has its maximum absorption at 440 ma, high transparency and suitable hue.
  • Example 3 In place of the coupler of Formula I in Example 1, 5 carboxy 2 ethoxy (4 octadecenylsuccinmonoamido)benzoyl acetanilide (Formula III) is used and treated as desecribed in Example l.
  • the yellow image so obtained has its maximum absorption at 441 ma, high transparency, land the sharpness 22 ml. of an aqueous 5% alkali solution (3.4 ml. of one normal solution of caustic soda is used per one gramme of coupler) of 3.5-dicarboxy-(4-stearoylmonoamido)benzoyl acetanilide (the comparative coupler) is mixed with g. of the silver halide photographic emulsion used in Example 1, adjusted to the pH value of 7.1- 8.0 with caustic soda or citric acid. The mixture is coated on a support such as lm, dried, then treated as described in Example l.
  • a support such as lm
  • the yellow image so obtained has its maximum absorption at 445 mp., and the absorption in the green region which affects the color reproduction is larger than the absorption obtained from the coupler according to this invention.
  • absorption curves 1, 2 and 3 of dyes obtained by development of a silver halide emulsion with a N,Ndiethylparaphenylene diamine in the presence of the compounds of Formulas I, and III and the comparative coupler having the structure shown in the legend of the drawing.
  • the spectroscopic absorption curves obtained by the normalized maximum absorption of visible region are used.
