Definitions

  • EP 2 93 917 also describes the use of thiosulfonic acids and their salts and esters as clearing agents in color film emulsions.
  • aromatic thiosulfonic acids have a super-sensitizing effect in infrared-sensitized emulsions. Since they have so far only been described as antifoggants and stabilizers in emulsions sensitized to visible light, this effect is surprising for the person skilled in the art.
  • Chemical ripening can be carried out using the known methods of sulfur, noble metal or reduction sensitization or else using suitable combinations of these methods.
  • the aromatic thiosulfonic acids according to the invention can be added before, during or after chemical ripening. If they are present in the emulsion during chemical ripening, they also act as clarifiers in the known manner.
  • the infrared sensitizers are preferably added to the emulsion after chemical ripening or shortly before application to the layer support. However, if they are sufficiently stable, they can also be used in earlier stages of emulsion production.
  • a monodisperse silver chlorobromide emulsion with 80 mole percent chloride with cubic grains with an edge length of 0.23 ⁇ m was produced by pAg-regulated two-jet inlet. 0.052 mg of rhodium (III) chloride had been added to the precipitation mixture. The emulsion was subjected to a flocculation washing process and a combined gold-sulfur sensitization.
  • Example 3 Before the digestion, 140 mg of sodium toluenesulfinate and if appropriate the compound I-2, then 400 mg of 4-hydroxy-6-methyl-1,3,3a, 7-tetraazaindene, 70 mg of benzotriazole, 750 mg of sodium octylphenyldi (oxyethyl) sulfonate, 25 mg of the sensitizer II-1 and, if appropriate, 65 g of the latex of Example 3 were added. The emulsion was applied together with a protective gelatin layer to a support as in Example 1. The recording material thus produced contained 4.3 g of silver and 3.5 g of gelatin per m2 on the recording side.
  • Example 4 The material was exposed as in Example 1 and processed in a roll developing machine for photoset material with a commercially available rapid developer of the hydroquinone-phenidone type at 34 ° C. in a total time of 120 s.
  • the reciprocal of the exposure required for a density of 3.0 above the minimum density was determined and, for each wavelength, related to the value 100 for the comparison test.
  • the result is shown in Table 4.
  • Example 5 Experiments were carried out after the comparative experiment from Example 4, in which the emulsion was sensitized with various sensitizers for the green, red and infrared spectral range with and without the addition of 75 mg of the compound I-1. The sensitivity was determined for each sensitizer at 407 nm and at the sensitization maximum. Table 5 shows the sensitivities of the test films containing the compound I-1 based on the value 100 for the films without this compound with otherwise the same sensitization.
