Definitions

  • the present invention relates to a method for processing an exposed silver halide color photographic material (the term “silver halide color photographic material” is hereinafter abbreviated to "color photographic material”) and, in particular, it relates to a method for processing an exposed color photographic material with sufficient desilvering in a short period of time to obtain a processed material having improved photographic properties.
  • the basic procedure for processing a color photographic material includes, in general, a color-development step and a desilvering step.
  • the color-development step the exposed silver halide in a color photographic material is reduced with a color-developing agent to yield silver, while the oxidized color-developing agent is reacted with a coupler to give a color image.
  • the desilvering step the silver formed in the previous color-developing step is oxidized by the action of an oxidizing agent (which is generally called a "bleaching agent”) and then dissolved by the action of a complexing agent for silver ions (which is generally called a "fixing agent").
  • an oxidizing agent which is generally called a "bleaching agent”
  • a complexing agent for silver ions which is generally called a "fixing agent”
  • the desilvering step is conducted either in a two-bath system using a bleaching agent-containing bleaching bath and a fixing agent-containing fixing bath or in a one-bath system using a bleach-fixing bath containing both a bleaching agent and a fixing agent.
  • a practical development procedure includes various auxiliary steps, in addition to the above-mentioned basic steps, for the purpose of maintaining the photographic and physical quality of the images formed and for improving the storage stability of the images formed.
  • auxiliary steps are conducted using a film-hardening bath, a stopping bath, an image-stabilizing bath and a rinsing bath.
  • the term "processing bath having a fixing ability" indicates both the fixing bath and the bleach-fixing bath.
  • the fixing agent for the bath having a fixing ability thiosulfates which are excellent in fixing capacity and are advantageous in view of their cost are generally used.
  • ferric complexes for example, aminopolycarboxylic acid iron (III) complexes, especically an (ethylendiaminetetraacetato) iron (III) complex
  • ferric complexes for example, aminopolycarboxylic acid iron (III) complexes, especically an (ethylendiaminetetraacetato) iron (III) complex
  • ferric complexes are relatively poor in oxidizability and insufficient in bleaching power. Accordingly, when they are used for bleaching or bleach-fixing a low-sensitivity silver halide color photographic material containing essentially a silver chlorobromide emulsion, the intended object can generally be attained.
  • JP-A-62-222252 a method of using a bleaching agent combination of a (1, 3-diaminopropanetetraacetato) iron (III) complex and an (ethylenediaminetetraacetato) iron (III) complex having an excellent bleaching power is known, as described in JP-A-62-222252 (the term "JP-A" as used herein means an "unexamined published Japanese patent application”).
  • aminopolycarboxylic acid which produces a compound, such as (1,3-diaminopropanetetracetato)iron (III) complex, having a low stability constant in binding to iron (III) is used, the compound causes a remarkable bleaching fog on a photosensitive material and insufficiency of recoloration of cyan dye, although it has a high bleaching ability.
  • Fuji Film Processing Manual, CN-16 Processing (October, 1985) has proposed a method wherein after processing a photographic material is fully rinsed or washed with water to remove the components of the bleaching solution from the processed photographic material. Although this method is effective to some degree, it interferes with rapid processing and additionally the number of the necessary processing baths must be increased. Accordingly, such a method is not suitable for use in a mini-laboratory system where rapid processability, small installation space and low processing cost are required.
  • Fig. 1 shows a partial sectional view of one embodiment of an automatic developing apparatus for the method of the present invention.
  • 1,3-DPTA ⁇ Fe (III) 1,3-diaminopropanetetraacetato iron (III) complex
  • the 1,3-DPTA ⁇ Fe(III) oxidizes the thiosulfate iron in the emulsion layer or near the surface thereof to give a sulfur compound, and the thus-formed sulfur compound strongly adheres to the silver halide in the material to retard the fixation procedure. Further, the sulfur compound, penetrated into the gelatin layer or adhered to the surface near the layer, causes the stains in the material.
  • a jet stream of a processing solution having a fixing ability is directed against the photographic material containing 1,3-DPTA ⁇ Fe(III), when the photographic material being processed is dipped in the processing solution having a fixing ability, whereby the diffusing of the 1,3-DPTA ⁇ Fe(III) from the emulsion layer of the material is noticeably accelerated, to thereby prevent the formation of the sulfur compound in the layer.
  • the application of the jet stream of the processing solution having a fixing ability to the emulsion layer of the photographic material being processed is conducted within 15 s after the material has been dipped in the processing solution having a fixing ability.
  • the color-developed photographic material is processed in a processing solution having a fixing ability, while a jet stream of the processing solution having a fixing ability is directed against the emulsion surface of the material being processed.
  • the jet steam of the processing solution having a fixing ability may be provided by pumping the solution having a fixing ability onto the emulsion surface of the photographic material being processed from nozzles provided in a position facing the emulsion surface of the material, the distance between the nozzle and the emulsion surface being preferably short, more preferably from 0.2 cm to 1.5 cm.
  • the device providing the jet stream may have from 10 to 200 nozzles, and a device having a large number of nozzles is better. Each nozzle has a diameter of from 1mm to 10mm, and preferably from 1mm to 5mm and, e.g., a square, round or hexagonal shape.
  • the speed of the jet stream (flow velocity)
  • flow velocity when it is directed against the emulsion surface, is preferred to be as high as possible within the range where the jet stream does not interfere with the conveyance of the photographic material, being processed in an automatic developing machine, and specifically, the flow velocity at the nozzle is preferred to fall within the range of from 0.3 m/s to 3 m/s , and more preferred from 2 m/s to 3 m/s .
  • the arrows from the jet stream pipe (17) indicate the jet stream of a bleaching solution or a fixing solution to be jetted from the nozzles provided in the jet stream pipe.
  • the bleaching solution (15) or the fixing solution (16) is introduced into the jet steam pipe (17) via the circulation pipe (19) under suction by the pump (18) At the position (4), the emulsion surface of the photographic material being processed faces downwards. In the bleaching bath (15) and the fixing bath (16), the emulsion surface faces the jet stream pipe.
  • the photographic material being processed is introduced into a bath of the solution having a fixing ability and the jet stream of the solution having a fixing ability is directed against the emulsion surface of the material within 15 s, after its introduction into the bath.
  • This time is the time from the contact of a certain point of the photographic material being processed with the processing solution having a fixing ability to the contact of the same point with a vertical jet stream of the processing solution.
  • the acceleration of the fixation by the application of the jet stream of the processing solution having a fixing ability prevents the retardation of fixation due to the 1, 3-DPTA ⁇ Fe(III) contained in the emulsion layer of the material being processed, and is basically different from the effect which would be attained in a different system using a bleaching agent of a conventional (ethylenediaminetetraacetato) iron (III) complex only.
  • another surprising effect of preventing stains in the processed photographic material can be attained.
  • a thiosulfate is generally used as the fixing agent.
  • this includes sodium thiosulfate, ammonium thiosulfate and potassium thiosulfate, and the use of ammonium thiosulfate is most preferred.

  • the bleaching solution for use in the present invention contains (1, 3-diaminopropanetetraacetato) iron (III) complex.
  • This complex may be in the form of an alkali metal salt such as a sodium or potassium salt, but the complex is preferably in the form of an ammonium salt, since the bleaching rate of the salt is excellent and it prevents the increase of the yellow density in the non-exposed areas of the processed photographic material.
  • the amount of the 1,3-DPTA ⁇ Fe (III) is preferably from 0.05 mol to 1 mol, more preferably from 0.1 mol to 0.5 mol, per liter of the bleaching solution.
  • any other (aminopolycarboxylato) iron (III) complexe can be incorporated into the bleaching solution together with the 1,3-DPTA ⁇ Fe (III), if desired.
  • A-1) Ethylenediaminetetraacetic acid (A-2) Diethylenetriaminepentaacetic acid (A-3) Cyclohexanediaminetetraacetic acid (A-4) 1,2-Propylenediaminetetraacetic acid
  • the molar proportion of the additional complex is 3 mol or less inclusive of 0 mol) per 1 mol of 1,3-DPTA ⁇ Fe (III), in view of the high bleaching power and the small bleaching fog, and more preferably from 0.1 to 3 mol, especially preferably from 0.1 to 1.5 mol, per mol of 1,3-DPTA ⁇ Fe (III).
  • a jet stream of the bleaching solution is directed against the photographic material being processed within 15 s after introduction of the material into the bleaching solution, in the same manner as in the processing step with the processing solution having a fixing ability, to promote acceleration of bleaching, prevention of bleaching fog, prevention of insufficiency in recoloration of cyan dye and acceleration of fixation.
  • the time is especially preferably within 10 s.
  • the bleaching solution for use in the method of the present invention has a pH value of from 5.5 to 2.0, more preferably from 5.0 to 3.0, most preferably from 4.5 to 3.5, for the purpose of attaining sufficient desilvering and of preventing bleaching fog.

  • the pH value is lower than that, the ferric complex in the bleaching solution precipitates.

Surprisingly, no insufficiency in recoloration of cyan dye occurrs in the method of the present invention, even when the pH value of the bleaching solution used is lowered, but rapid bleaching can be effected under such a low pH condition.
  • the material to be processed is directly introduced into the bleaching solution, without the material being processed with any other intermediate processing solutions (such as a rinsing solution), from the viewpoint of acceleration of the processing.
  • the crossover time from the color-developer to the bleaching solution i.e., the time from removing the photographic material being processed from the color-developer to its introduction into the bleaching solution, is desirably 10 s or less, preferably 5 s or less, especially preferably 3 s or less, whereby the processed photographic material may be effectively prevented.
  • the transfer speed of the film between the processing tanks can be elevated (in general, the linear velocity is elevated), or the conveyance of the film between the processing solution tanks is effected at a position lower than the liquid level of the first tank or at the position falling within the range of from 0 to several cm from the liquid surface of this tank, whereupon it is preferable to provide a dead space between the tanks for the purpose of intermixing of the processing solutions of the respective tanks. Any of these methods can be employed in the practice of the present invention.
  • the linear velocity in the processing procedure is generally lower than that for a large-sized machine, and the apparatus is required to be small and inexpensive, but it is difficult to shorten the crossover time to 10 s or less, for example 3 s or less.
  • the bromide ion concentration in the bleaching solution is preferably from 1.2 mol/l (or 118 g/l as NH4Br) to 3.0 mol/l, more preferably 1.5 to 2.8 mol/l and most preferably 1.7 to 2.5 mol/l whereby the yellow density increase is substantially reduced to 0.

  • shortening of the crossover time from the bleaching solution to the processing solution having a fixing ability to 10 s or less is preferred, since insufficiency in recoloration of cyan dye can be prevented under such conditions. It is more preferred that the crossover time is shortened as much as possible (i.e., to 5 s or less, especially to 3 s or less) from the viewpoint of the rapid processing of the method of the invention. Under such conditions of shortened crossover time, the effect of the present invention is remarkable.

  • Such means are preferably used for increasing the stirring of the fixing solution and bleach-fixing solution as well as bleaching solution.
  • the increase of the stirring of the processing solution is considered to accelerate the introduction of the bleaching agent and the fixing agent into the emulsion layer of the photographic material being processed, and as a result, to elevate the desilvering rate in the processing step.
  • the stirring acclerating means is more effective when a bleaching accelerator is used, whereby the bleaching accelerating effect can be noticeably enhanced and the fixation retardation or insufficiency may be eliminated because of the bleaching accelerator.
