Definitions

  • a photographic color image by developing a reducible silver salt image in the presence of a color coupler, i.e. a compound which during development couples with the oxidation product of the developing agent and forms a dyestufl on the area where the silver salt is reduced.
  • a color coupler i.e. a compound which during development couples with the oxidation product of the developing agent and forms a dyestufl on the area where the silver salt is reduced.
  • the modern methods of color photography are based upon the subtractive color principle according to which differently sensitized silver halide emulsion layers are superposed, each of them containing a color coupler which produces the subtractive yellow-, cyanand magenta-dyestufl images by development in a solution containing a primary aromatic amine.
  • the new color couplers can be prepared by condensation of a l-hydroxy-Z-naphthoic acid or a derivative thereof with the aromatic amine desired.
  • a sulfonic acid group it is advantageous to bring into the naphthol resp. anilide group before the condensation a sulfofluoride group which after condensation is saponified to the corresponding sulfonic acid, e.g. by application of the method described in Belgian patent specifications 584,152 and 590,934.
  • the color couplers must be incorporated into a photographic silver halide emulsion which in its turn is incorporated into a material having one or more layers.
  • the color couplers can be incorporated into said emulsions by means of the usual colloids such as gelatin, polyvinyl alcohol, collodium or other natural or synthetic colloids such as e.g. those prepared according to the Belgian patent specification 568,153.
  • the silver halide emulsions can be applied to a support consisting of paper, glass, nitrocellulose, cellulose esters such as cellulose triacetate, polyester, polystyrene or an other natural or synthetic resin.
  • This multilayer material is usually composed of the following layers: a support, a red-sensitive emulsion layer having a color coupler for cyan, a green light-sensitive emulsion layer with color coupler for magenta and a blue-light sensitive emulsion layer having a color coupler for yellow. Between the blue-light sensitive and the green-light-sensitive emulsion layer, there is a yellow filter layer which in most cases consists of colloidal silver.
  • the new color couplers into the light-sensitive silver halide emulsion layer itself but they can also be incorporated into an adjacent non-light-sensitive colloid layer or into a non-lightsensitive layer which is separated from the light-sensitive emulsion layer by a water-permeable colloid layer.
  • aromatic amino-compounds can be used as developers for such material: mono-, diand triaminoaryl compounds, more especially N,N-dialkyl-p-phenylene diamine and its derivatives such as N,N-dialkyl-N'- sulphomethylor carboxymethyl p-phenylenediamine.
  • mono-amino-developer aminophenols and aminocresols, or their halogen derivatives and also the aminonaphthols are considered.
  • Example 1 10 parts of N-[(2-cetylmercapto-5-sulfo)phenyl]-1- hydroXy-4-bromo-2-naphthoic acid amide sodium salt are wetted with 40 parts of ethanol. The whole is dissolved by adding 20 parts of water and by heating at 40 C. This solution is diluted with Water up to 200 parts till obtaining a 5% solution. 200 parts of this color coupler solution and 260 parts of Water are added to 500 parts of silver bromo-iodide gelatin emulsion (2% iodide). After adding the usual additives such as hardening agents and wetting agents the emulsion obtained is coated onto a photographic support. After drying, the photographic material is exposed and treated with a developing solution of the following composition:
  • N,N-diethyl-p-phenylenediamine hydrochloride 2.75 Sodium sulphite 2 Potassium carbonate 75 Potassium bromide 0.5 Hydroxylamine hydrochloride 1.2 Sodium hexametaphosphate 1.0
  • This material is rinsed for 30 seconds and fixed in a fixing bath of the following composition:
  • Example 2 10 parts of N (2-cetylmercapto-5-sulfophenyl)-1-hydroxy-4-chloro-2-naphthoic acid amide sodium salt are wetted with 20 parts of ethanol dissolved into 180 parts of water. Now the color coupler solution is incorporated into the emulsion according to Example 1. The material is exposed and treated in the same way as described in Example 1. A cyan image is obtained which shows loW side-absorptions.
  • Example 3 10 parts of N-(o-cetylmercaptophenyl)-1-hydroxy-4- chloro-2-naphthoic acid amide are wetted with 30 parts of ethanol and dissolved in 25 parts of 1 N sodium hydroxide and parts of water. The color coupler solution is brought into the emulsion as described in Example 1. The emulsion is neutralized by 7.5 parts of acetic acid N/2 per 100 parts of color coupler solution.
  • Example 1 After exposure, the material is treated according to Example 1 whereby in the color developing bath 4-amino-N-ethyl- N (,8 methylsulfonamidoethyl)-rn-toluidine sesquisulphate monohydrate is substituted for N,N-diethyl-p-phen.-
  • Example 5 200 cm. of a solution 5% of N-(4-cetylmercapto-5- sulfophenyl) -1-hydroxy-4-sulfo-2-naphthoic acid disodium salt (10 g. of color coupler dissolved in cm. of ethanol and cm. of sodium hydroxide N/ 2 diluted with water to 200 cm?) are added to 500 cm. of a red-sensitized silver bromo-iodide emulsion (2% iodide). After acidification with acidic acid N/ 2 to a pH 6.5, the total volume of the emulsion is brought to 1 1.
  • This emulsion is coated onto a support which alreay is coated with an anti'nalation layer.
  • a gelatin intermediate layer on which is coated a greenlight-sensitive emulsion layer with color coupler for magenta and covered with a yellow filter layer consisting of a thin gelatin layer containing colloidal silver.
  • a blue-light-sensitive emulsion layer with a color coupler for yellow On this filter layer is then coated a blue-light-sensitive emulsion layer with a color coupler for yellow.
  • This layer is coated with an antistress layer.
  • the photographic material obtained is dried, exposed and color developed according to Example 1. In this way an image with a subtractive color reproduction of the original is obtained which has an increased transparency in the green.
  • methyl Cellosolve is a registered trademark for (ethylene glycol monomethyl ether) manufactured by Union Carbide and Carbon, New York, and is used in the foregoing specification.
  • X is selected from the group consisting of a bromine atom and chlorine atom
  • Y represents a member selected from the group consisting of a hydrogen atom, a sulfonic acid group and a sulfonate group
  • R is a hydrocarbon radical having a chain length of about 5-20 carbon atoms and sufficient to render said color coupler resistant to difiusion.
  • Light-sensitive element comprising a red light-sensitive silver halide emulsion layer and a l-hydroxy-Z-naththoic acid anilide color coupler for cyan for said layer, said color coupler being selected from the group consisting of compounds having the formulae:
  • X is selected from the group consisting of a bromine atom and a chlorine atom
  • Y represents a member selected from the group consisting of a hydrogen atom, a sulfonic acid group and a sulfonate group
  • R is a hydrocarbon radical having a chain length of about 5-20 carbon atoms and sufiicient to render said color coupler resistant to diffusion.
