Abstract

A method for processing a silver halide light-sensitive material employing an automatic processing machine is disclosed.

Description

[0001] The present invention relates to a method for processing a silver halide light-sensitive photographic material (hereinafter occasionally referred to as a light-sensitive material), and to a method for processing a silver halide light-sensitive photographic material which is subjected to minimized processing unevenness during running processing.

[0002] After imagewise exposure, black-and-white silver halide light-sensitive photographic materials are generally processed employing steps consisting of development, fixing, water washing, and drying. Of said steps, it is generally carried out that in the fixing step, by processing said light-sensitive materials employing a fixer comprising a water-soluble aluminum salt (a so-called hardening fixer), the drying time is shortened by hardening the layer of said light-sensitive materials and thus the conveyance of said light-sensitive materials is improved in an automatic processing machine (hereinafter occasionally referred to as an automatic processor).

[0003] Incidentally, for the past few years, from the viewpoint of environmental safety, a decrease in the effluent volume of processing solutions has been demanded. From the viewpoint of a decrease in the processing cost of said effluent, the decrease of said effluent is preferred. However, when the replenishment rate of a fixer is decreased, problems have occurred in which when a silver halide light-sensitive material is conveyed to a fixing tank from a developer tank, development is not stopped uniformly in the fixer, and as a result, the density of black silver formed in the exposed area is not uniform. Said adverse fact has hindered achievement of low replenishment rate of said fixer.

[0004] Further, when the pH is raised, said hardening fixer, comprising water-soluble aluminum compounds, forms sparingly soluble aluminum salts. In order to minimize the formation of said sparingly soluble salts, the pH may be lowered. However, since thiosulfate salts are incorporated as the fixing agent, a problem occurs in which the fixing agent undergoes sulfurization. Due to said fact, the fixer is generally employed in the range of a pH of 4.2 to 5.4. However, in said pH range, it is impossible to hinder the formation of sparing soluble aluminum compounds. Specifically, when the replenishment rate of a fixer is decreased as described above, the formation of sparingly soluble aluminum compounds is adversely affected. In order to overcome these drawbacks, a large amount of boron compounds is commonly employed. Said boron compounds are carried over to the water washing tank by the light-sensitive material and so-called eutrophication tends to result and scale staining of the water washing tank also results. On the other hand, it has been known that boron compounds may be replaced with organic acids. For example, Research Disclosure (hereinafter referred to as RD) 18728 discloses an example in which organic acids such as gluconic acid, glycolic acid, and the like, are employed instead of boron compounds. In others, such as RD 16768, Japanese Patent Publication Open to Public Inspection (abbreviated as JP O.P.I.) No. 63-284546, and the like, examples are described in which organic acids are employed as the substitutes. However, processing unevenness is not sufficiently improved, and thus more improvement is demanded.

[0005] Further, the decrease in the replenishment rate results in various problems. For instance, silver from silver halide light-sensitive photographic materials (hereinafter occasionally referred to as light-sensitive materials) deposits in the development tank of automatic processing machines, and the deposited silver adheres onto the conveyance rollers, so that the adhered silver is transferred onto the silver halide light-sensitive photographic material, resulting in staining. For the purpose of minimizing such staining, JP O.P.I.. No. (abbreviated as JP O.P.I.) No. 11-149142 describes a means in which the silver stain is decreased by adding a certain compound to a developer. Incidentally, current replenishers are supplied in a concentrated solution form. When photographic processing was carried out employing a replenisher which was prepared by using a concentrated solution comprising the aforementioned compound, problems occurred in which the sensitivity decreased during running processing and oily sludge adhered onto the silver halide light-sensitive photographic materials.

[0006] In order to overcome said problems, the inventors of the present invention have investigated the supply employing a solid developer and have been able to overcome the problems.

SUMMARY OF THE INVENTION

[0007] It is an object of the present invention to provide a method for processing a silver halide light-sensitive photographic material in which silver stain (black spots) caused by a decrease in the replenishment rate, and further a decrease in sensitivity as well as oily sludge adhesion, which is caused by photographic processing during running processing employing a replenisher prepared by employing a usual concentrated solution is minimized.

[0008] It is another object of the present invention to provide a method for processing a silver halide light-sensitive photographic material in which during photographic processing employing an automatic processing machine, staining of the water washing tank, as well as processing unevenness which is generated by a decrease in the replenishment rate of a fixer, is minimized.

During mixing said core grains, 8×10−8 mole of K3RuCl6 per mole of silver was added. Said core grains were covered with shells, employing a double-jet method. At that time, 3×10−7 mole of K2IrCl6 per mole of silver was added.

[0265] The obtained emulsion was a core/shell type monodispersed tabular grain silver chlorobromoiodide (comprised of 90 mole percent of silver chloride, 0.2 mole percent of silver iodide, and 9.8 mole percent of silver bromide) emulsion, at an average thickness of 0.10 μm and an average diameter of 0.25 μm (having a variation coefficient of 10 percent) and a (100) plane as the principal plane.

[0266] Subsequently, desalting was carried out employing modified gelatin (in which the amino group of said gelatin was substituted with phenylcarbamyl, such as, for example, exemplified compound G-8 described in JP O.P.I. No. 2-280139), which is described in JP O.P.I. No. 2-280139. After said desalting, the EAg was 190 mV at 50° C.

[0267] Added to the obtained emulsion was 1×10−3 mole of 4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene (ST-1) per mole of silver, and by adding potassium bromide and citric acid, the pH and the EAg were then adjusted to 5.6 and 123 mV, respectively. After adding 2×10−5 mole of chloroauric acid, 3×10−6 mole of inorganic sulfur was added and the resultant emulsion underwent chemical ripening at 60° C. until the maximum sensitivity was achieved. After ripening, 2×10−3 mole of ST-1 per mole of silver, 3×10−4 mole of 1-phenyl-5-mercaptotetrazole (ST-2), and gelatin were added.

While mixing said core grains, 2×10−7 mole of K3IrCl6 per mole of silver was added. Said core grains were covered with shells, employing a double-jet method. At that time, 3×10−7 mole of K2IrCl6 per mole of silver was added.

[0270] The obtained emulsion was a core/shell type monodispersed tabular grain silver chlorobromoiodide (comprised of 90 mole percent of silver chloride, 0.5 mole percent of silver iodide, and 9.5 mole percent of silver bromide) emulsion at an average thickness of 0.10 μm and an average diameter of 0.42 μm (having a variation coefficient of 10 percent).

[0271] Subsequently, the obtained emulsion was desalted employing the same modified gelatin as that used in the preparation of Emulsion A. After desalting, the EAg was 180 mV at 50° C.

[0272] Added to the obtained emulsion was 1×10−3 mole of ST-1 per mole of silver, and by adding potassium bromide and citric acid, the pH and the EAg were then adjusted to 5.6 and 123 mV, respectively. After adding 2×10−5 mole of chloroauric acid, 3×10−5 mole of N,N,N′-trimethyl-N′-heptafluoroheptylselenourea was added and the resultant emulsion underwent chemical ripening at 60° C. until the maximum sensitivity was achieved. After ripening, 2×10−3 mole of ST-1 per mole of silver, 3×10−4 mole of ST-2, and gelatin were added.

[0313] Hydroquinone was pulverized at a mesh of 8 mm and a rotation frequency of 25 Hz, employing a Mikro-Pulverizer AP-B, manufactured by HOSOKAWA MICRON CORP. KBr was sized to a mesh of 0.25 mm, employing a commercially available sizer.

[0314] Blending of Components

[0315] The components described below were blended for 15 minutes employing a commercially available V-type blender (having a capacity of 200 liters).

	Hydroquinone (said pulverized one)	42.57	kg

[0316] From randomly selected points (5 locations) of the obtained mixture, 50 g from each location was individually sampled and analyzed. As a result, it was found that the concentration of each component was within ±1 percent of said formula value and blending was considered to have been carried out sufficiently and uniformly.

[0317] Molding

[0318] Said mixture was molded under conditions of a pocket shape of 5.0 Φmm×1.2 mm (in depth), a rotation frequency of the roller of 15 rpm, and a rotation frequency of the feeder of 24 rpm, employing a compression granulator Briquetter BSS-IV Type, manufactured by Shinto Kogyo Co., Ltd. The obtained plate shaped mold was granulated employing a sizer to classify 2.4 to 7.0 mm granules and 2.4 mm or less fine granules (while 7.00 mm or more granules were regranulated). The 2.4 mm or less granules were blended into said mixture and the resultant mixture was returned to a compression molding machine and remolded. According to the method described above, about 68 kg of developing agent granule DA were obtained.

[0319] 2) Preparation of Alkali Granule DB

[0320] Preparation of Components

[0321] Dissolved in 400 ml of ethyl alcohol were 556 g of 1-phenyl-5-mercaptotetrazole. A small amount of the resultant solution was dripped into 20 kg of anhydrous sodium carbonate which was rotated employing a mixer, and the rotation was continued until the mixture was sufficiently dried. From randomly selected points (5 locations) of the obtained mixture, 10 g from each location was individually sampled and subsequently analyzed. Then it was considered that 1-phenyl-5-mercaptotetrazole was sufficiently and uniformly mixed. The obtained mixture was designated as M-1.

[0323] After blending, 1.37 kg of sodium 1-octanesulfonate were added and blended for further 5 minutes.

[0324] Molding

[0325] Said mixture was molded under conditions of a pocket shape of 5.0 Φmm×1.2 mm (in depth), a rotation frequency of the roller of 15 rpm, and a rotation frequency of the feeder of 44 rpm, employing a compression granulator Briquetter BSS-IV Type, manufactured by Shinto Kogyo Co., Ltd. The obtained plate shaped mold was granulated employing a sizer to classify 2.4 to 7.0 mm granules and 2.4 mm or less fine granules (while 7.00 mm or more granules were granulated). The 2.4 mm or less granules were blended into said mixture and the resultant mixture was returned to a compression molding machine and remolded. According to the method described above, about 68 kg of alkali granule DB were obtained.

[0326] Packaging (10-liter kit of working solution)

[0327] A 10-liter capped polyethylene bottle was filled with molded granules and LiOH·H2O in the order described below.

[0330] After adjusting the total volume to 5 liters, by adding water, the resultant mixture was placed in the same container in which said granule agent was placed. In order to minimize degradation due to aerial oxidation, 10 liters of nitrogen gas was bubbled into the bottle which was then sealed with its cap to obtained 10 liters of packaged concentrated developer 101. After storing said concentrated developer 101 at 30° C. for one month, a replenisher was prepared. Concentrated developer 102 was prepared in the same manner as concentrated developer 101, except that the compound of the present invention was replaced with (l)-3.

[0331] (Preparation of Working Replenisher)

[0332] Said solid developer 103 was placed in 9 liters of tap water which was stirred by a commercially available stirrer for about 40 minutes to obtain 10 liters of the replenisher (which was available for the starting solution as well as the replenisher). The pH of the obtained working replenisher was 10.55. By doubly diluting the 10 liters of said concentrated developer 101 by water, a working replenisher was prepared. The pH of the resultant replenisher was 10.55 which was the same as that of the solid developer.

[0333] The fixer same as employed in 105 of Example 1 was employed.

[0334] (Processing and Evaluation)

[0335] Each of the samples of light-sensitive materials, which had been obtained, was exposed employing FTR-3050, manufactured by Dainippon Screen Co., Ltd., and was processed employing an automatic processor LD-T 1060, manufactured by Dainippon Screen Co., Ltd. The processing conditions are described below. The combinations of light-sensitive materials with types of developers are shown in Table 5.

[0337] For 10 days, continuously processed per day were 610×508 mm 200 sheets, in which 10 percent of the total area of each sheet was exposed. Then, the sensitivity, gamma, black spots, and the adhesion of oily sludge on the light-sensitive material were evaluated.

[0338] (Evaluation of Sensitivity and Gamma)

[0339] Step exposure was carried out employing a sensitometer utilizing a 660 nm He/Ne laser beam as the light source, while varying the light amount at 1.5×10−7 second, and photographic processing was carried out under said processing conditions. The obtained processed sample was measured employing PDA-65 (Konica Digital Densitometer).

[0340] In Table 5, the sensitivity was expressed as the relative sensitivity, when the sensitivity of the sample processed by Developer Type 101 was 100 at a density of 2.5. Further, the gamma was expressed employing a tangent of density of 0.1 and 3.0. In Table 5, when the gamma value is 10 or more, it shows that ultra-hard images are obtained.

[0341] (Evaluation of Black Spots)

[0342] Each of the obtained processed samples was visually evaluated employing a 10 power magnifier , and was graded into 5 ranks of 5, 4, 3, 2, and 1 in the order of decreasing black spots. Ranks 1 and 2 were considered to be commercially unviable. Table 5 shows the obtained results.

[0343] (Evaluation of Oily Sludge)

[0344] After running processing, unexposed samples were processed and the sample staining was subjected to sensory evaluation based on the ranks described below.

[0345] Rank 1: oily sludge adhered the whole area

[0346] Rank 2: intermediate between Rank 1 and Rank 3

[0347] Rank 3: adhesion was observed, but resulting in no problem for commercial viability

[0348] Rank 4: intermediate between Rank 3 and Rank 5

[0349] Rank 5: no staining was observed.

[0350] Ranks 1 and 2 were considered to be not commercially viable. Table 5 shows the obtained results.

[0374] Added to 200 g of toluene were 100 g of styrene, 56 g of triisobutyl aluminum, and 234 g of pentamethylcyclopentadienyl titanium trimethoxide, and the resultant mixture underwent reaction at 96° C. for 8 hours. After removing the catalyst, upon its decomposition, employing a methanol solution of sodium hydroxide, washing was carried out three times employing methanol to obtain 34 g of the target compound.

[0375] (Preparation of SPS Film)

[0376] The obtained SPS was melt-extruded into a film employing a T die, and then solidified upon rapidly cooling the resultant film on a cooling drum to obtain an unstretched film. At that time, cooling drum receiving speeds were carried out at two stages. The resultant 1370 μm, 1265 μm and 1054 μm thick unstretched films were preheated at 135° C.; longitudinally stretched (by a factor of 3.1); and then laterally stretched (by a factor of 3.4) at 130° C.; and further thermally fixed at 250° C. As a result, 130 μm and 100 μm thick biaxially stretched films, having a bending elastic modulus of 4.41×109 Pa, were obtained.

While mixing said core grains, 2×10−7 mole of K3IrCl6 per mole of silver was added. Said core grains were covered with shells, employing a double-jet method. At that time, 3×10−7 mole of K2IrCl6 per mole of silver was added.

[0386] The obtained emulsion was a core/shell type monodispersed tabular grain silver chlorobromoiodide (comprised of 90 mole percent of silver chloride, 0.5 mole percent of silver iodide, and 9.5 mole percent of silver bromide) emulsion at an average thickness of 0.10 μm and an average diameter of 0.42 μm (having a variation coefficient of 10 percent).

[0387] Subsequently, the obtained emulsion was desalted employing the same modified gelatin as that used in the preparation of Emulsion A. After desalting, the EAg was 180 mV at 50° C.

[0388] Added to the obtained emulsion was 1×10−3 mole of ST-1 per mole of silver, and by adding potassium bromide and citric acid, the pH and the EAg were then adjusted to 5.6 and 123 mV, respectively.
