Definitions

  • the invention relates to granulated photo chemicals and a process for their production.
  • Photographic processing baths e.g. Developmental, bleaching and fixing baths usually contain the required active ingredients in low concentrations and are therefore prepared by the user himself from water and chemical concentrates as well as, if necessary, other auxiliaries.
  • the concentrates should be dosed as simply as possible and should be largely dust-free. In addition, no unnecessarily high costs should arise for packaging and transport.
  • the liquid concentrates which are generally used in practice for the production of ready-to-use photographic baths have the advantage over the previously used, powdered products that no dust development and no solution problems occur.
  • the concentrates have the disadvantages of the high proportion by weight and volume of water, as well as difficulties in disposing of the bulky packaging.
  • the object of the invention is therefore to find means with which a larger spectrum of photographic processing chemicals can be granulated, the dust content should be further reduced.
  • the granules should also dissolve in water in a short time.
  • the invention therefore relates to photographic processing chemicals in the form of granules with an average particle diameter of 150 to 3000 microns, containing the necessary active ingredients and auxiliary substances, characterized in that the granules additionally contain a polymer having a molecular weight of 500,000 to 14,000,000 in one Amount from 1 to 1000 mg / kg of granules, preferably from 50 to 150 mg / kg of granules, containing at least 80 mol% of acrylamide, acrylic acid, cationic Monomer, or mixtures of acrylamide and cationic or anionic monomer.
