Definitions

  • Thisinvention relates to developers for colorphotography which have been stabilized by the addition of. 1,3-diamino-2-propanol tetracetic acid thereto.
  • devolopin'g solutions are concerned primarily with the treatment of color materials having a coupling component present in the differentially sensitized layers for coupling with the oxidation products of the color developer.
  • an object of my invention to provide photographic developing solutions for color photography which can be stored for extended periods of time without substantial loss of the eifective concentration of the active ingredients.
  • Still another object is to provide a method for making such solutions.
  • My invention provides a means of stabilizing photographic developing solutions of the type under consideration by the addition of 1,3-diamino-2-propanol tetracetic acid to the developing solutions. It has been shown in the art that this tetracetic acid derivative can be used in photographic developing solutions (U. S. Patent 2,656,- 273), although it was quite unexpected that this compound, which had been shown to be useful as a sequestering agent, could also be used to stabilize an otherwise unstable developing solution containing an alkali metal sullfite, an hydroxylamine salt and an ethylenediamine sa t.
  • 1,3-diamino-2-propanol tetracetic acid I mean the compound represented by the following formula HOOC-CH: OH OHzCOOH NOH2&'HCH2N HOOC-CHz CHtCOOH
  • HOOC-CH OH OHzCOOH NOH2&'HCH2N
  • HOOC-CHz CHtCOOH
  • the tetracetic acid derivative employed in my invention is employed in combination with a phenylenediamine color developer which upon oxidation couples with the conventional coupling components employed in incorporated coupler photography.
  • Such phenylenediamine developing agents include the hydrochloride or sulfate of N,N-diethyl-pphenylenediamine, N methyl p-phenyl enediamine, N,N-dimethyl-pphenylenediamine, Z-amino- S-diethylaminotoluene, 4-amino-N-ethyl-NJfi-methanesulfonamidoethyH-ni-toluidine, etc.
  • the amount of 1,3-diamino-2-propanol tetracetic acid added to the developing composition will vary somewhat, depending upon the particular developing agent employed and amounts of other ingredients present. In general, the concentration of the tetracetic acid can vary from about 0.2 g. to about 2.0 g. per liter.
  • solution A An aqueous solution, designated solution A, was prepared having the following composition:
  • solution B A second solution, designated solution B was prepared identical with solution A except that it contained 1.0 g. per liter of 1,3-diamino-2-propanol tetracetic acid. These two solutions were then stored for two weeks at 75 F., both in closed, tightly-stoppered bottles and in open con- Firm 24.11 959 tainers. By chemical analysis, the loss of concentration of sodium sulfite and hydroxylamine sulfatewas 'deter mined. r
  • Patent 2,673,800 was exposed in the usual manner to an appropriate subject.
  • the exposed color film was then developed in a black-and-white developer for six minutes, the developer having the following composition:
  • the color material was then washed for eight minutes and subdued'room lights turned on after the washing had begun. seconds on each side at a distance of one foot from a No. 1 Photofiood.
  • the re-exposed material was then color developed for four minutes in a developer of the type having the composition shown above and then treated in a second stop bath having the following composition:
  • alkali metal carbonate such as sodium carbonate,- potassium carbonate, etc.
  • alkali metal hydroxide such as sodium carbonate,- potassium carbonate, etc.
  • a photographic developing composition comprising an alkaline solution of 1,3-diamino-2-propano1tetracetic acid, sodium sulfite, hydroxylamine sulfate, ethylenediamine sulfate, and 4-arnino-N-ethyl-N-[B-methanesulfonamidoethyl]-m-toluidine sesquisulfate monohydrate.
