Description

FIELD OF THE INVENTION

The present invention relates to a manufacturing method for a solid processing composition for processing a silver halide light sensitive photographic material, particularly to providing a manufacturing method for a solid developing composition.

BACKGROUND OF THE INVENTION

Photographic silver halide materials are generally exposed imagewisely, developed, fixed, washed with water, and then dried, thereby the photographic image is finally observed.

The processing composition used in these process are provided as concentrated solution kits, thereafter these kits are diluted when practically used as working solutions. The concentrated solution kits have an advantage from the viewpoint of excellent solubility, moreover, since there can be wide range of selection of agents including liquid state raw materials, thereby the concentrated solution kits are prepared at less burden in manufacturing processes and at low manufacturing cost.

However, the concentrated solution kits have some dangerous problem such as a contact with skin. Especially the problem becomes more serious when these kits penetrate into eyes. Moreover, the kits must need heavy plastic bottles to contain them. Excessive weight and large volume of processing vessels not only causes increasing transportation cost but also environmentally unacceptable problem with large amount of disposal of the waste vessels.

Accordingly, from the viewpoint of small light weight and compact, the processing composition in the kits is preferably a solid such as a powder form, a granule form, and a tablet form.

However, as mentioned above, compared with a liquid form, a solid form has a big problem in manufacturing cost because it must be passed through various processes, namely, process of measuring raw materials, mixing process, pulverizing process, granulating process, drying process, and dressing process, furthermore, in the case of a tablet form, compressed tableting process is included.

Accordingly, to supply the solid form to the market at similar price to that of the liquid form, there exists the subject that attains to lower the manufacturing cost of the solid form. On the other hand, there is a problem of the deterioration of the properties of the solid processing composition, such as the occurrence of dust, the lowering of it's stability, and the lowering of it's solubility.

SUMMARY OF THE INVENTION

An object of the invention is to provide a manufacturing method for a solid processing composition with a large cut down of manufacturing cost, further, to provide a manufacturing method for a solid developing composition with a preferable handling property, namely, a solid developing composition with improved solubility, with stability in the manufacturing step, and with stability with the passage of time.

The solid processing composition of the invention is manufactured by using a stirring granulation process. The following is the explanation for the granulation in the invention.

The granulation is identified with manufacturing the grains which have approximately unified shape and size made from powdery, massive, and liquid raw materials. As for the granulating processes, it is possible to use any of the well known processes such as the process of a rolling granulation, an extrusion granulation, a compression granulation, a pulverizing granulation, a stirring granulation, a fluidized bed granulation and a spray-drying granulation, wherein the method for manufacturing the solid processing composition of the invention is the stirring granulation method.

The stirring granulation method is the method to utilize the agglomeration property of powder and this method is excellent in mixing ability. According to this method, the granulation is performed by stirring powder as a raw material and a small amount of solution with stirring blade in a fixed vessel.

At least part of the stirring granulation process is performed under the atmosphere of 35.degree. C. to 120.degree. C., preferably 50.degree. C. to 90.degree. C. Furthermore, it is preferable that the atmosphere is kept during stirring.

Preparation of the Solid Processing Composition for Developing Solution

As the stirring granulation machine, Henschel mixer FM20C/I type produced by Mitsui Mining Co., Ltd. whose maximum capacity was 20 liter, was used. Two stirring blades were equipped.

As the lower blade near the bottom mixing vessel, Ao type (for general use) was equipped, and as the upper blade, Zo type (for kneading use) was equipped. The temperature in the mixing vessel was adjusted by circulating warm water set up as described in Table 1 and 2 through the jacket surrounding the mixing vessel of Henschel mixer.

The temperature adjusted in the granulation process was shown in Table 1 and 2.

______________________________________[Preparation of solid developer composition]______________________________________(1) Compound represented by formula (1) 1700 g (see Table 1, 2) (2) Sodium metabisulfite 500 g (3) 1-Phenyl-3-pyrazolidone 150 g (4) N-Acetyl-D,L-penicillamine 5 g (5) Glutaraldehyde-bisodiumsulfite 200 g (6) Sugar derivative 250 g (see Table 1, 2) (7) Compound represented by formula (3) 28 g (see Table 1, 2)______________________________________ Granulation

The granulation was performed by changing the combination of above-mentioned processing agents (1) to (7) as shown in Table 1 and 2. First, the processing agents (1) to (6) were added into the mixing vessel as shown in Table 1 and 2. Hereinafter, the granulation process of the invention was divided as follows for convenience.

Process A: stirring mixture. Process B: granulation process by pouring water. Process C: stirring mixture to facilitate granulation still more.

By dividing the granulation process into these three processes, the powdery granule was produced under the condition shown in Table 1 and 2. In the case of temperature difference between the above-mentioned processes, next process is performed after adjusting the temperature of the jacket water. Furthermore, the compound (7), which is represented by formula (3), was added into the mixing vessel after finishing the process C, and was stirred still more 30 seconds.

The rotation rate of the stirring blades was 600 rpm in the process A, 1800 rpm in the process B, and 600 rpm in the process C.

Water was dropped into the mixing vessel constantly by using a pipette for time set up in the process B shown in Table 1 and 2.

Measurement of Particle Diameter of the Powdery Granule

The particle distribution was measured by using both micro electromagnetic vibration sieve M-100 produced by Tsutsui Rikagakukikai Co., Ltd. and sieve analysis with mesh standardized by Japanese Industrial Standard (JIS). The vibration time was 5 minutes.

Producing Tablet

The obtained powdery granules were tableted in an amount per tablet of 10 g, using the tableting machine which was improved type of the rotary tableting machine such as Tough Press Correct Model 1527HU produced by Kikusui Seisakusho Co., Ltd. The cylindrical developer tablet with the diameter of 30 mm was obtained.

Evaluation of Tablet Hardness

Each of several groups consisting of twenty fresh developer tablets containing the same ingredients was prepared. The hardness of these fresh developer tablets obtained by the above method was measured by using a hardness measuring machine (TS-75NL produced by Okada Seikosha Co., Ltd.), and an average value of the hardness of each of several groups consisting of twenty tablets was defined as the hardness of tablet in this invention. The larger hardness of tablet expresses an excellent tablet and more than 35 kg of hardness is a preferable hardness for practical use.

Evaluation of Tablet Storage Hardness

Each of several groups consisting of twenty tablets was enclosed in a moistureproof bag made from polyethylene terephthalate which was vacuum-evaporated by aluminum. Each bag was allowed to stand under the high constant temperature 50.degree. C. for 30 days, and to check up the heat resistance of the tablet, the hardness of these tablets preserved under the high constant temperature was evaluated in the similar manner as used in evaluating the hardness of fresh tablets mentioned above.

The results thereof will be shown collectively in Table 1 and 2.
