Definitions

  • the present invention relates to a process for the production of a silver image including a stabilisation-fixing treatment of an image-wise exposed and developed photographic silver halide emulsion material to obtain an image having improved heat and/or light stability.
  • Stabilising baths for exposed and developed photographic silver halide emulsion layers which contain a large variety of organic mercapto compounds are state of the art and particulars concerning such baths are described, e.g. in the book "Modern Photographic Processing” Vol. 2 of Grant Haist - A Wiley Interscience Publication - (1979) New York - p. 210-227.
  • the stabilising agent forms an insoluble non-lightsensitive silver compound while the fixing agent forms a soluble silver complex.
  • solubility of said compounds in a given medium varies inter alia with the pH-value of the medium.
  • one compound may be effective as stabilising agent as well as a fixing agent depending on the pH-value of the processing bath.
  • a solution is used containing at least one compound (A) and (B).
  • Compound (A) is an iodide of alkali metals and ammonium.
  • Compound (B) corresponds to the following general formula : wherein :
  • a process for the production of a silver image including a stabilising-fixing treatment of said image formed by development of an imagewise exposed photographic silver halide emulsion material is provided wherein the imagewise exposed and developed silver halide emulsion material is treated with an aqueous solution containing an alkali metal thiosulphate and a cyclic thiourea compound corresponding to the following general formula (X) or a corresponding tautomeric structure thereof : wherein :
  • Table 1 contains a list of specific compounds within the scope of the above general formula (X) with a literature reference for their preparation.
  • the specified heterocyclic compounds are simply dissolved in water together with the other ingredients.
  • the pH of the treating liquid is in the acidic range, e.g. in the range of 6 to 4.
  • Small amounts of water-soluble solvents, e.g. acetic acid and water-miscible alcohols may be added to improve the dissolution of the cyclic thiourea compound.
  • the treating liquids used according to the present invention contain an anti-oxidizing agent to shield the cyclic thiourea compound from aerial oxidation.
  • Suitable anti-oxidizing agents are ascorbic acid and compounds yielding sulphite ions such as sodium sulphite and potassium metabisulphite.
  • the present image-stabilising process makes it possible to eliminate the customary washing procedure and yet to obtain a satisfactory stable print.
  • the treatment of the developed silver image with the above aqueous solution containing alkali metal thiosulphate ions and the cyclic thiourea compound corresponding to the general formula (X) may be preceded by a rinsing treatment but such is not strictly necessary.
  • the image-stabilising liquids used according to the present invention do not alter the binding properties of gelatin, so that no sticky gelatin silver halide emulsion layers are obtained as is the case when using stabilising liquids based on thiocyanates. Further no particular odour is produced and toxicity and corrosivity are very low.
  • the stabilising-fixing treatment according to the present invention is particularly effective for the stabilisation of silver images obtained by means of silver halide emulsion layers wherein the silver halide is for at least 50 mole % silver chloride.
  • the present stabilising-fixing treatment is very effective when used in conjunction with silver halide emulsion layers having a silver halide coverage, the silver halide being expressed in an equivalent amount of silver nitrate, not higher than 4 g per sq.m.
  • the treatment according to the present invention provides image stabilisation in a short time.
  • Stabilising treatment according to the present invention may be terminated in 30 s at room temperature (20°C) and may be terminated in 15 s at 35 °C.
  • the stabilising-fixing treatment can be used for photographic black-and-white papers and films, e.g. graphic art film materials, but is likewise applicable for the image stabilisation of photographic colour materials wherein residual silver halide may not remain.
  • the photographic materials may contain already before the exposure some or all of the developing agent(s) used in the development step.
  • the developing agents When the developing agents are present already in the photographic material during the exposure the development may be carried out with a so-called activator bath which is an alkaline aqueous liquid being free from developing agents and activates these agents already present in the photographic material.
  • the silver images stabilised according to the present invention show a very low darkening in the non-image area under circumstances of heat, humidity and/or light-exposure.
  • the washing liquid likewise incorporates a said cyclic thiourea compound, e.g. in an amount up to 1x10 mole per liter.
  • the application of the treating liquids used in the processing of photographic silver halide emulsion materials may proceed by immersion but more advantageously proceeds by meniscus coating using a lick-roller, sponge or resilient roller to limit the volume of applied liquid .
  • an image-wise exposed silver halide emulsion material according to the present invention it is in favour of effective stabilisation to keep the pH of the liquid(s) containing said cyclic thiourea compound in the acidic range and therefore to eliminate as much as possible of the alkaline developing or development activating liquid from the material before applying the stabilising liquid.
  • Such may proceed by squeegee, e.g. with rollers or by applying an intermediate rinsing step.
  • Said photographic material was treated in unexposed state for 10 s at 20°C with an alkaline aqueous activator liquid having the following composition :
  • the developed material was led between squeegee rollers to remove the major part of adhering alkaline liquid and was then dipped for 5 s at 20 °C into a fixing or stabilising-fixing liquid as defined in the following Table 2.
  • Liquid no. 1 contained per liter 198.5 g (0.80 mole) of sodium thiosulphate.5 water and 25 g of potassium metabisulphite.
  • Liquid no. 2 had the same composition as liquid no. 1 but included in addition thereto per liter 10 g of 2-thio-hexahydropyrimidone-2.
  • the fixing-stabilisation was followed by rinsing.
  • the rinsing was effected by conveying the material for 10 s at 20 °C through a tray containing plain water.
  • the efficiency of the stabilisation was determined by measuring the change in optical density ( ⁇ D) obtained after keeping one strip (i) of the processed material for 3 days in the dark at 35 °C at 80 % relative humidity and another strip (ii) for 4 h in a XENOTEST (trade name) exposure apparatus wherein the strip was subjected to a white light illumination of 180,000 lux.
