Definitions

  • the images obtained in light-sensitive silver halide emulsion layers often undergo changes during processing among others during hot glazing or mechanical drying, at high temperature. During these treatments loss of density occurs easily by the so-called bronzing of the silver image.
  • R represents an aryl group or a substituted aryl group
  • R represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl p,
  • R and R represent a hydrogen atom, a lower alkyl group or a substituted lower alkyl group
  • n a positive integer from 1 to 5
  • the disadvantages caused by hot glazing or mechanical drying are prevented.
  • Suitable compounds corresponding to the above general formula are e.g.:
  • the light-sensitive silver halide emulsion wherein compounds according to the present invention can be incorporated can be any silver halide emulsion such as a gelatinosilver chloride emulsion, a gelatino-silver chloro-bromide emulsion, a gelatino-silver chloroiodide emulsion, a gelatino-silver bromide emulsion, a gelatino-silver bromoiodide emulsion, and a gelation-silver chlorobro
  • the compounds according to the present invention can be added during any stage of the preparation of the emulsion, e.g. during the formation of the silver halide or during the physical or chemical ripening, but preferably after the chemical ripening.
  • the amount, in which the compounds according to the present invention may be added depends on the emulsion used but it generally varies from 2 to 20 g. per 1000 g. of silver nitrate.
  • the compounds according to the present invention are present in the light-sensitive composition in the form of a colloidal dispersion.
  • the compounds according to the present invention in a hydrophilic layer adjacent to the light-sensitive layer e.g. in the covering layer, or in another layer from which, during fixation, they can e.g. diffuse to the silver halide emulsion layer.
  • concentration in which the compounds according to the invention are incorporated into these layers is mostly the same as or slightly higher than their concentration when added to the light-sensitive layer.
  • the compounds according to the invention are sometimes incorporated into a processing bath e.g. in the fixing bath.
  • poly(N-vinylpyrrolidone) gives as anti-bronzing agent still better results.
  • poly(N-vinylpyrrolidone) can be incorporated into the light-sensitive laver and/or into an other water permeable layer at the same side of the support as the light-sensitive layer, in a concentration which preferably varies from 20 to 80 g. per mole of silver halide.
  • Example 1 To an ammoniacal gelatino-silver bromoiodide emulsion containing 3.5 mol percent of silver iodide based on the total amount of silver halide and having a medium gradation are added per mole of silver halide 1.9 g. of the silver salt of a-mercapto-butyric acid-p-toluidide in the form of a dispersion.
  • This emulsion is applied on a baryta-coated paper support in such a way, the light-sensitive layer contains per sq. m. an amount of silver halide equivalent to 2 g. of silver nitrate.
  • On this emulsion layer a gelatin-containing convering layer is coated.
  • This material is exposed under a step-wedge, developed, fixed and rinsed. Then it is subjected to high glossing by pressing its image side against a heated polished metal surface. The reflection densities are measured by means of a MacBeth densitometer before and after subjecting the material to high glossing. The following results are obtained:
  • Example 2 Three materials are prepared starting from an ammoniacal gelatino-silver bromoiodide emulsion as described in Example 1.
  • the first material the comparison material
  • no anti-bronzing agent is added to the emulsion.
  • the second and the third material respectively of 0.45 g. of the silver salt of a-rnercapto-butyric acid-p-toluidide and 0.45 g. of the silver salt of ,B-mercapto-propionic acid-ptoluidide are added to the emulsion per mol of silver halide.
  • a photographic material comprising a support and at least one light-sensitive silver halide emulsion layer and containing the silver salt of a-mercapto-butyric acid-ptoluidide in at least one water permeable layer which is situated at the same side of the support as the lightsensitive silver halide emulsion layer.
  • a photographic material comprising a support and at least one light-sensitive silver halide emulsion layer and containing the silver salt of fl-mercapto-propionic acid-p-toluidide in at least one water-permeable layer which is situated at the same side of the support as the light-sensitive silver halide emulsion layer.
