Definitions

  • ABSTRACT Composition for processing a silver halide photographic light-sensitive element containing ethylenebis(,B'0xyethylamine) tetraacetic acid or its alkali salt.
  • the compound has a calcium ion-chelating or masking ability superior to that of EDTA.
  • water which contains a high calcium ion content i.e., so.called hard water, reacts with carbonates, sulfites, borates or like salts present in the processing agents to form water-insoluble calcium salts.
  • Such calcium salts adhere to the photographic light-sensitive element to be processed (this is called the production of scum), and the solidified calcium salts mayinjure the emulsion layer of the photographic light-sensitive element.
  • the calcium salts may be deposited in the processing apparatus, ultimately causing breakdown of the apparatus.
  • Ethylene diamine tetraacetic acid (EDTA) or its alkali salt is atpresent considered the most excellent calcium masking agent, but, when added to a processing composition containing an organic reducing agent such as a developing agent, it willaccelerate the oxidation of the organic reducing agent such as a developing X 0 O CH: C
  • composition of processing agents includes the processing agents in the form of both liquid and powder.
  • the calcium masking agents according to the present invention show in particular remarkable effect when added into a composition of photographic processing agents containing an organic reducing substance such as a developing agent, although they may be added into any composition of photographic processing agents which contains calcium ions, for example, hard water.
  • Such compositions of processing agents include fixing solutions, bleaching solutions, hardening solutions, stopping solutions and stabilizing solutions.
  • Formulation of each composition of processing agents is in no way limited so far as the composition'has its function, because the effect of the compounds of the invention is basically connected with the calcium-containing water itself. Although the fore-going description of the agent, thereby reducing the stability thereof. Such a phenomenon. is inparticular prominent when iron is present in the processing composition.
  • One object of the present invention is to provide a composition of processing agents for use in processing invention has been made with particular reference to the calcium-containing water, it will be apparent that the same effect is encountered when other liquids containing calcium ionsare used as a solvent for the processing agents.
  • the amount of the compound according to the invention is in the rangeof from 0.1 to 10, preferably from 0.5 to 3g. per liter of photographic processing solution.
  • composition of photographic processing agents as herein described and hereinafter claimed may be applied to solutions for processing black and white photographic light-sensitive elements including X-ray films, lith-films, microfilms, printing paper and the like, and color photographic lightsensitive elements.
  • Example 1 As the auto-developer for a direct X-ray film for medical use there was prepared a liquid composition of the following formulation.
  • the calcium ions can be masked by the Developer B according to the present invention and the affect of calcium ions can be reduced to one third that in the Developer C containing EDTA.
  • Example 2 Using Developers A to C in Example 1, the difference in hydroquinone-oxidation velocity between the case of solutions containing a low iron ion content and the case of a high iron ion content was investigated.
  • the oxidation of hydroquinone was carried out under the same conditions in every case by air-oxidation.
  • the air-oxidation was effected at room temperature using vessels in which the surface area of the developer surface in contact with air and the volume of the developer were identical in every case, thereby effecting a natural air-oxidation. The results are shown in the following table.
  • Example 3 to the method described in Example 2.
  • the exposure, development, measurement of photographic density and the like were all effected in a conventional manner, using the same conditions in every case.
  • Example 4 Ammonium thiosulfate 150.0 g. Anhydrous sodium sulfite 15.0 g. Boric acid 10.0 g. Acetic acid aqueous solution) 23.0 c.c. Anhydrous aluminum sulfate 9.0 g Water to make I liter Into a fixing solution of the above-described formulation there was dissolved calcium carbonate and white turbidity was observed at a concentration of 4 g/l calcium carbonate.
  • Example 5 Formulation of Developer D Para-amino-N,N-diethylaniline sulfate 2.0 g. Anhydrous sodium sulfite 2.0 g. Sodium carbonate monohydrate 60.0 g. Hydroxylamine hydrochloride 0.5 g. Potassium bromide 0.4 g.
  • prevention of developing agent oxidation by means of the compound of the invention is superior to that by using EDTA.
  • a developing composition comprising a black and white or color silver halide developing agent and a sequestering agent, wherein the improvement comprises said sequestering agent being at least one of ethylene bis(beta-oxyethylamine)tetraacetic acid and its alkali metal salts at a level such that when a developing solution is formed from said composition, said ethylene bis-' beta-oxyethylamine)tetraacetic acid or its alkali metal salts are present at a level of from 0.1 to 10 g. per liter of said developing solution.
  • a developing composition as claimed in claim 1 which is in the form of a liquid.
  • a method for preventing the air oxidation of an aqueous photographic developing composition containing a black and white or color developing agent for an exposed silver halide element by the addition of a ous solution contains iron ions.
  • a developing composition as claimed in claim 1 which is in the form of a powder.
