Definitions

  • R is a mononuclear aryl radical substituted with at least one alkoxycarbonyl group having at least 9 carbon atoms; and R is a lower alkyl group.
  • the present invention relates to color photography and particularly color photographic materials containing improved colored couplers.
  • cyan couplers used as color formers in color photography are l-naphthl-2-carb0xylic acid derivatives or aminophenol derivatives.
  • a long-chain alkyl group or a dialkylphenoxy group is introduced into the coupler molecule as a group for giving diffusion resistance to the couple-r.
  • an aryl group is introduced into the 2-position of the naphthol nucleus of a cyan colored coupler, as a method for improving the color, solubility in water-insoluble, high boiling point solvents (hereinafter these solvents are called simply coupler solvents) is lowered.
  • couplers having a branched alkyl group at the 2-position of the naphthol nucleus as couplers having good solubility in coupler solvents, and being easily prepared.
  • Couplers have a very long wave length absorption maximum of 505 to 510 m
  • cyan colored couplers having the longer wave length absorption maximum and a large green absorption are more profitable in color correction.
  • magenta-colored cyan couplers which have sufiicient solubility in coupler solvents, and which are prepared by using inexpensive materials and simple procedures.
  • a further object is to provide magenta-colored cyan couplers having bathochromic absorption maximum and a large green absorption.
  • couplers in which one or more higher alkoxycarbonyl groups are introduced to the aryl group at the 2-position of the naphthol nucleus according to this invention.
  • couplers of this invention are selected from the group consisting of compounds with the general formula:
  • each of the couplers is dissolved in tricresyl N 3 phosphate, the optical absorption curves are measured and they are plotted in the figures by setting the maxi- I mum optical density to 1.0.
  • Curve (A) is the spectroscopic absorption curve of Coupler (I) of this invention, Curve (B) that of above-mentioned comparative Coupler (a) and Curve (C) that of comparative Coupler (0) described in Japanese Patent No. 508,680.
  • the couplers of this invention have maximum absorption at longer wave length than CONHCHZOmCHmCH that of the coupler described in Japanese Patent No. O 508,680, which is very profitable in color correction effect. Furthermore, the maximum absorption of the (30m coupler of this invention is at a little longer wave length than those of the coupler having an aryl group at the 2-position of the naphthol nucleus, but having a longchain alkyl group bonded to the aryl group by an acid Q amide bond and the couplers having no substituents at the aryl group. Accordingly, the introduction of a higher (30002115 (b) alkoxycarbonyl group to the aryl radical at the 2-position OH r of the naphthol nucleus is profitable in this point also.
  • the product was mixed with 1,000 ml. of methanol and cooled to form crystals, which were collected by filtration and rinsed with 200 ml. of methanol.
  • the recrystallization from methanol gave 221 g. (yield 73%) of the product.
  • the melting point of the product was 82-84" C.
  • the product was dissolved in 300 ml. of ethanol and the solution was cooled by ice to precipitate crystals, which were collected by filtration and rinsed with 100 ml. of methanol.
  • the thus obtained diazonium salt solution was added at temperatures of below 8 C. in a solution of 24 g. of the l-hydroxy-2-(4 -dodecyloxycarbonyl) naphthanilide, obtained by above-mentioned (l-B), in 400 ml. of pyridine to conduct coupling and the thus precipitated crystals were collected by filtration, rinsed with 1,000 m1. of water containing 50 ml. of hydrochloric acid and further 2,000 ml. of water, recrystallized from 500 ml. of diethyl formamide, and then rinsed with 100 ml. of methanol. By the treatment, 30 g. (yield 91%) of the coupler was obtained. The melting point of the coupler was 165l66 C. and the analytical value of nitrogen was 6.26% (calculated 6.46%
  • EXAMPLE 1 Into 10 parts of tricresyl phosphate was dissolved 1.25 parts of the coupler having structure (I) by heating to 80 C. and the solution was mixed with 100 parts of an aqueous 10% gelatin solution pre-heated to 60 C. The solution was further mixed with 2 parts of-an aqueous 10% solution of sodium alkylbenzene sulfonate and the system was stirred for 5 minutes by using a high speed rotary mixer at about 65 C. with an interruption of 1 minute, the stirring being repeated 5 times to give an emulsified dispersion of the coupler.
  • the film was exposed to red light using an optical wedge and developed as usual in a color developing solution having the following composition:
  • the film was exposed to red light using an optical wedge, developed, bleached and fixed as in Example 1 to give a positive red image having very excellent transparency and a cyan-colored negative image.
  • the maximum absorption wave length thereof is shown in the following table.
  • Example 2 Example 3
  • Example 3 Example 3
  • the dispersion was mixed with a silver halide light-sensitive emulsion and coated on a film base as in Example 1 to give a red-sensitive color photographic light-sensitive material.
  • the photographic film was then exposed, colordeveloped, bleached and fixed to give a positive red image having very excellent transparency and a cyan-colored negative image.
