Definitions

  • This invention relates to a light-sensitive photographic material which contains silver salts of sulfur-containing aliphatic carboxylic acids as light-sensitive compounds.
  • Silver halides are used as light-sensitive compounds in conventional photographic materials.
  • Organic silver salts, for example mercaptides, have also been proposed for this purpose, but have not been used in practice because they are not sufficiently light-sensitive or suffer from other disadvantages.
  • photographic elements which contain silver salts of sulfur-containing aliphatic carboxylic acids as light-sensitive compounds.
  • alkyl preferably with up to 18 carbon atoms, such as benzyl or phenylethyl, aryl such as phenyl or naphthyl, or heterocyclic rings such as diazolyl, oxazolyl, triazolyl, oxidiazolyl, thiadiazolyl, azaindenyl, preferably tetraor pentaazaindenyl, benzthiazo'lyl, naphthiothiazolyl, benzooxazolyl, naphthoxazolyl, pyridyl, quino-linyl, pyrimidyl, quinoxalinyl, quinazolinyl, which radicals may in turn be substituted, for example, by alkyl, preferably with up to 18 carbon atoms, aryl such as phenyl or naphthyl, hydroxyl, alkoxy with preferably up to 12 carbon atoms, aroxy such as phenoxy, acyl preferably
  • alkyl groups of which having up to 5 carbon atoms acylamino with preferably acyl groups being derived from aliphatic carboxylic acids having up to 18 carbon atoms or aryl-substituted amino preferably a phenylamino, mercapto groups, mercapto groups substituted with alkyl having up to 18 carbon atoms, a phenyl, a naphthyl or a heterocyclic radical, halogen such as chlorine or bromine, sulfo groups or carboxyl groups and the like, and
  • Sulfur-containing aliphatic carboxylic acids useful accord- R'(S) XCOOAg ing to the invention include the following: 1 184 C:
  • the compounds can be isolated in the form of free acids or as alkali metal salts.
  • the compounds can be purified by recrystallisation from or by solution and reprecipitation from water or alcohol. This is more fully described in the following examples:
  • the solution is heated for 15 minutes on a steam bath while stirring.
  • 50 g. of soda are then added in portions at about 60 C., after which the solution is heated for 3 hours on a steam bath and after cooling the product is precipitated by acidification with 50% aqueous acetic acid.
  • the crude product is purified by washing with water.
  • the resulting 65 g. of crude product are dissolved in an equivalent quantity of 5% aqueous soda solution, after which the sodium salt of the product is isolated in the form of fine needles by concentration.
  • the salt melts at 218 C. after washing with acetone and drying in vacuo.
  • Compounds 129-135 are prepared by reacting a Scange base with a mercapto-substituted aliphatic carboxylic acid as described for example by Stacy et al., J.A.C.S. 77, 3869, 1955.
  • the preparation of conventional silver halide emulsion involves three separate steps: (1) precipitation of the silver halide in the presence of a protective colloid preferably gelatin and physical or Ostwald ripening, (2) flocculation and freeing of the emulsion of excess water-soluble salts, and (3) the chemical or after-ripening to obtain increased speed and sensitivity (compare Mees The Theory of the Photographic Process).
  • novel photographic emulsions of the present invention can be prepared in analogous manner.
  • the silver salts are prepared from equimolar quantities of the thioaliphatic carboxylic acid and the soluble salt such as silver nitrate.
  • the reaction takes place in an aqueous solution of the reaction components, preferably in the presence of a protective colloid such as gelatin, polyvinyl alcohol, or sodium alginate.
  • a protective colloid such as gelatin, polyvinyl alcohol, or sodium alginate.
  • the components are forming binding agent reacted in a molar ratio about 1:1. That molar ratio relates to the number of carboxyl groups.
  • an acid Which contains two carboxyl groups is preferably reacted with 2 mols of water-soluble silver salt such as silver nitrate.
  • Acids which contain 3 or more oarboxyl groups are preferably reacted with a least 2 mols of silver salt.
  • the most effective and suitable molar ratio will be apparent to those skilled in the art upon making the ordinary tests and observations customarily used in the :art of emulsion making. It has been found that an excess of water soluble silver salt produces fogging in the photographic emulsion. On the other hand, an excess of thioaliphatic carboxylic acid up to about 10 mol percent reduce the fog level without affecting sensitivity. A higher excess of the thioaliphatic carboxylic acid is not desirable since the lightsensitivity of the silver salts of the said acid is considerably reduced.
  • Water soluble organic as silver complexes may thioaliphatic carboxylic salts used to prepare the vention may itself for example, as a quired pH-value.
  • the silver salts according to the invention may also be employed in admixture with one another or with conventional silver halides.
  • silver silver salts as well be used for the reaction with the acid.
  • si-ons can also be sensitized with by R. Koslowsky, Z. wiss. photo.
  • the emulsion can also be optically sensitized with the
  • the emulsions may be hardened by any suitable hardener, such as formaldehyde, halogen substituted aliphatic acids such as mucobromic acid.

  • aqueous sodium hydroxide solution can be mixed with a small amount of aqueous sodium hydroxide solution to facilitate solution, are added at 40 C. to 1 litre of an 8% by weight aqueous gelatin solution. ml. of a 10% aqueous solution of silver nitrate are then added with vigorous stirring and digested for a few minutes at 40 C. After the addition of a wetting agent, for example 5 ml. of 30% by weight aqueous solution of saponin, and a hardening agent, for example 1 ml. of a 30% by weight formaldehyde solution, the emulsion is applied in known manner into a sheet of paper or into a transparent support for example of polyethylene terephthalate and dried.
  • a wetting agent for example 5 ml. of 30% by weight aqueous solution of saponin
  • a hardening agent for example 1 ml. of a 30% by weight formaldehyde solution
  • the sensitivity of the coated material is similar to that of conventional photographic silver chloride contact-copying papers. After exposure, the material may be developed, fixed and treated with water in the usual way.
  • the developer composition referred to an Example 1 can be used. Since the silver salt is precipitated in a very fine-grain form, these emulsions can be prepared which have a low silver content as compared with a conventional silver halide emulsion without affecting the density of the final images.
  • compound 126 it is also possible to employ the following compounds in the quantities indicated: 14 g. of compound 111; 13 g. of compound 121; 21 g. of compound 16 g. of compound 124 or 16 g. of compound 119.
  • Example 5 30 ml. of a 40% aqueous solution of citric acid are added to 1 litre of an 8% by weight aqueous gelatin solution, and the solution is heated to 45 C. 15 g. of compound 109 dissolved in water mixed with a little aqueous sodium hydroxide solution are then added, after which precipitation is carried out while stirring vigorously with 100 ml. of a 10% by weight aqueous solution of silver nitrate. Before casting, 3 ml. of a 1% by weight alcoholic solution of 1-phenyl-5-mercaptotetrazole, 5 ml. of a 1% by weight alcoholic solution of benztriazole, 1 ml. of a 30% by weight formaldehyde solution and 5 ml. of a 30% aqueous solution of saponin are added. The emulsion is applied to a sheet of paper in known manner and dried.
  • the material is exposed and further processed in accordance with the silver salt diffusion process by developing the exposed light-sensitive layer, while in contact with a transfer sheet containing development nuclei and separating the sheets when the transfer of the silver salt is completed. Since the silver salt dissolves readily in an alkaline sulfite solution, it is not necessary to apply a silver salt solvent such as sodium thiosulfate in the developer bath or in the transfer sheet. An excellent copy of the original is obtained.
  • Example 6 2 ml. of a 40% aqueous solution of citric acid are added to 1 litre of an 8% by weight aqueous gelatine solution, and the solution is heated to 40% C. 15 g. of compound 118 dissolved in water mixed with a small amount of sodium hydroxide solution are then added, after which precipitation is completed while stirring vigorously with 100 ml. of a 10% by weight aqueous silver nitrate solution. Before casting, 125 g. of crystalline sodium acetate, 5 g. of potassium metabisulfite, 5 g. of sodium 4-diethylaminobenzene-l-aminomethane sulfonate and 5 ml. of a 30% aqueous solution of saponin, are added. The solution is applied to a sheet of paper and dried.
  • the material After exposure, the material can be developed under heat, or used as a light-sensitive material for a developer sublimation process as described for example in German patent specification No. 1,159,758.
  • a light-sensitive photographic element having at 2.
  • X represents an alkylene radical having up to 5 carbon atoms.
  • R is a heterocyclic radical of the group consisting of a quinolyl, a pyrimidyl, a quinoxalyl, quinazolyl, phthalazyl, triazolyl and thiazolyl.
