Definitions

  • This invention relates to a method of producing colored photographic materials.
  • c represents the carrier or support, whilst b is a silver bromide gelatine layer colored, for example, with Chrysophenine G (36e), which has been precipitated with hydrochlorid 2-pheny14aminoquinoline
  • c is the carrier or support, b an uncolored silver bromide gelatine layer, and a; a gelatine layer colored, for example, with Chrysophenine G (304i), which has been precipitated with hydrochloric 2-phenyl-4-aminoquinoline.
  • Figure 3 shows a similar material to Figure 2 with reverse order oi the layers c and b, that is to say--a is applied to the support and b situated over e.
  • Figure 4 shows a form of embodiment having three dierently colored silver bromide layers.
  • c is a backing or support of desired material, and
  • d, e and f are silver bromide gelatine layers colcred as follows:-
  • d contains Diamine pure blue FF (424),4 e Chrysophenine G 3de. and ,f Amidonaphthol red 6B (66).
  • FF Chrysophenine G 3de.
  • ,f Amidonaphthol red 6B 66.
  • Each of these dyestuffs is precipitated in the emulsion by 'Z-phenyl--aminoquinoline
  • the index numbers for the dyestuis given in the abovev refer to the Schultz Dyestuif Tables, 5th Ed., 1920.
  • the salts in question may be incorporated in finished state in the layers or emulsions in nnesuspension or by way of addition in a mutable solvent, for example alcohol, or these deposits may be produced in the layer itself by double decomposition.
  • a mutable solvent for example alcohol
  • These non-diffusing salts of the dvestuf may be incorporated in those layers, which consist of a plurality of part layers poured 5 one over the other or of a plurality of particles lsuch as result from the known re-emulsifying action of diierently colored emulsions.
  • They may also be formed by applying, atomizing or impressing the dyestui on to a colloidal layer, l0 whereby there is employed eithera solution of the dyestu salts, or the same may be employed together with the organic bases for coloring the arrangements as described, or the dvestuif deposit may be formed in the layer itself by way '15 of double decomposition.
  • This method of xing dyestui's may also be employed for other purposes, for example in the transfer method, in which, for example, an organic base is introduced into the colloid used for the transfer, and an insoluble non-diffusing salt of the dyestui there formed after the transfer has taken place. In this method the transfer images are extremely sharp, owing to prevention of the dilusion. This method is also extremely useful for the pro- 25 duction of anti-halo layers.
  • Layers containing, for example, substantive dyes, which may be removed entirely from the gelatine by Washing, may be applied to the emulsion carrier on the front or the rear side of a film or plate or immediately above or below the emulsion.
  • the suitable salt of an organic base for example 2-phenyl-4- aminoquinoline, with Ponceau 4R.
  • This salt may be split in a caustic alkaline developer and the dyestuii thereupon removed by washing.
  • the resulting salts possess varying powers of dissociation, and it is desirable for color photographic purposes to employ a merely weak alkaline neutral or acid developer.
  • Metanil yellow (138) is admixed with hydrochloric Z-phenyl-a-amino-quinoline.
  • the number of useful salt forming organic bases is extremely large. It is also possible to 'employ alkaloids, for instance quinine or cinchonine.
  • the dyestufl isbrought together with a salt of the bases in a solution and the resulting deposit .subsequently dissolved in alcohol or another suitable solvent and added to the gelatine. 55
  • the procedure may also be such that the dyestui'i is added to'a part of the gelatine and one of the 0r the layer may contain the bases and subsequently be colored with vdyestuii, or, vice versa, the dyestufr may b e included in the layer, and subsequently treated with a base for the purpose of producing the dyestui! deposit.
  • A'colorless gelatine solution is admixed with au alcoholic solution of hydrochloric 2phenyl4 amino-quinoline, and a ne grain suspension of the quinoline salt is caused.
  • the gelatine is poured onto paper, and transfer images, for example pina type images, formed on the layers thus produced. 'Ihe resulting pictures ar, extremely sharp, owing to the lack oi' diffusion.
  • a photographic material consisting of a support and at least two superimposed layers
  • At least one layer contains a substantially water insoluble salt of a colorless nitroge- 2 0 nous organic base and an acid dyestun.
