Definitions

  • the present invention relates to a granulated, color photographic developer and a manufacturing method of such a developer who quickly resolved can be.
  • Color photographic developers usually include a number of solid components, e.g. the real one Developer substance, antioxidant, complexing agent, Sodium sulfite, alkali donors and alkali halides. Because these compounds react chemically with each other can, they are assembled separately and first mixed immediately before use.
  • Such color developers are processed in the publication "Agglacolor Selst, Der Negativ / Positiv-Prozess ", pages 10, 11, 36, 37 (1972)”. Suitable assemblies are powders and liquid concentrates, the latter changing more and more over the years have prevailed, especially since some developers liquid Contain ingredients that understandably do not can be made up in powder form, for example Benzyl alcohol.
  • the three or four concentrates in certain mixing ratios and optionally with the addition of Water mixed with stirring.
  • the invention thus relates to a method for Production of a granular preparation of the solid Components of a color photographic developer, thereby characterized in that the antioxidant, the developer substance and the alkali donor of a color photographic developer separated on one Particle size ⁇ 10 microns, then optionally with the addition of a granulating liquid and a binder subject to powder agglomeration and in vacuo dries, mixes the individual granules and is water vapor-tight packed up.
  • the granules of the solid components thus produced of a color photographic developer are mechanical stable, of uniform grain size, show a large Solution speed and unlimited durability are dust-free and free-flowing.
  • the crushing of the solid components to particle sizes ⁇ 10 ⁇ m is usually done by jet milling.
  • the powder agglomeration is preferably carried out in a fluidized bed performed, taking the one to be agglomerated Particles optionally granulating liquid, for example Add 200 ml water per kg powder and if necessary some binder, such as corn starch.
  • the average particle diameter of the granules is ⁇ 150 ⁇ m and is in particular 150 to 3,000 ⁇ m.
  • a protective gas for example nitrogen.
  • the other components of the developer like anti-limescale, Complexing agent for heavy metal ions, sodium sulfite and alkali halide can also form granules processed and mixed into the mixture.
  • each of these additives with one of the three essential ones Granulate components (developer substance, antioxidant or alkali dispenser) and to granulate.
  • Suitable color developer compounds are aromatic compounds of the p-phenylenediamine type containing at least one primary amino group, for example N, N-dialkyl-p-phenylenediamines such as N, N-diethyl-p-phenylenediamine, 1- (N-ethyl-N-methanesulfonamidoethyl) -3 -methyl-p-phenylenediamine, 1- (N-ethyl-N-hydroxyethyl) -3-methyl-p-phenylenediamine and 1- (N-ethyl-N-methoxyethyl) -3-methyl-p-phenylenediamine.
  • Other useful color developers are described, for example, in J. Amer. Chem. Soc. 73 , 3106 (1951) and G. Haist
  • Another object of the invention is a granulate mixture containing at least 3 different granules of integral parts of a color photographic Developer, a granulate containing the antioxidant, a granulate the developer substance and a Granules containing the alkali dispenser, and the middle one Particle diameter of the individual granules at least Is 150 ⁇ m.
  • 1 kg of crystallized hydroxylammonium sulfate is in an Alexander sieve with a mesh size of 0.6 mm and then in an air jet mill on one average particle diameter ⁇ 10 ⁇ m milled.
  • the granules are 90 min. at 40 ° C in a vacuum post-dried.
  • Mixture C Mixture D a) Disodium salt of 1-hydroxyethane-1,1-diphosphonic acid 34 g --- b) Sodium sulfite 39 g 39 g c) Ethylenediaminetetraacetic acid --- 24 g d) Potassium carbonate 336 g 336 g e) Sodium bicarbonate 15 g 15 g f) Potassium bromide 15 g 15 g 439 g 429 g
  • the individual granules A, B, C and D are mixed in the following weight ratio in a laboratory mixer, whereby work must be carried out with the exclusion of moisture: Granules A 2.4 g Granules B 4.52 g Granules C 21.95 g Granules D 21.45 g total weight 50.32 g
  • the mixed granulate is excluded from moisture (Transfer of very dry air) with plastic and aluminum foil laminated paper bags that be welded shut immediately.
