Description

The present invention relates to a method for processing a silver halide color photographic light-sensitive material (hereinafter sometimes simply referred to as a light-sensitive material), and in particular, adhesion of a light-sensitive material after processing and light of a magenta dye even after long-term processing. The present invention relates to a processing method that makes it difficult to cause a fading or reading error of magnetic information.

Generally, the basic processing of a silver halide color photographic light-sensitive material is a color development step and a desilvering step, and other auxiliary steps are processed using a processor called an automatic processor. Since the developing agent contained in the color developer is susceptible to oxidative deterioration due to air, hydroxylamine is added to the color developer for photographic light sensitive materials such as color negative film to prevent the deterioration. Addition of alkyl-substituted hydroxylamine has been widely practiced in color developers for light-sensitive materials such as silver chloride color paper. In the desilvering step, the silver produced in the color development step is oxidized by the action of an oxidizing agent called a bleaching agent contained in the bleaching solution, and then silver ions called a fixing agent contained in the fixing solution are oxidized. It is dissolved and removed from the photosensitive material by a solubilizer. Photographic materials for photography preferably have high sensitivity for that purpose. Therefore, silver halide containing silver iodide is used, and the amount of coated silver is larger than that of photosensitive materials such as color paper. It is common. As a result, more excellent desilvering properties are required, and a method in which the steps are divided into a bleaching solution and a fixing solution is generally adopted instead of the same process method of bleach-fixing as in color paper.

On the other hand, from the standpoint of protecting the global environment, materials that are excellent in biodegradability, such as ethylenediaminetetraacetic acid and 1,3-diaminopropanetetraacetic acid, which have been widely used as bleaching agents, are not easily biodegradable in nature. The use has been desired, and several compounds are described in Patent Documents 1, 2, and 3, for example.
JP-A-4-313752 JP-A-5-265159 JP-A-6-161065

However, with respect to the photographic material, the color developer contains hydroxylamine, and the processing is continued for a long time with a processing solution containing these bleaching agents in the bleaching solution, so that the processed photosensitive material is easily adhered. Thus, for example, it has been confirmed that there is a problem that it is difficult to take out a color negative film from a bag called a negative sheet, or that the light fading of a magenta dye among dyes forming an image tends to deteriorate. Further, it was confirmed that the photosensitive material having a magnetic recording layer described in International Publication No. WO 9/04205 has a problem that the reading performance of magnetic information is remarkably deteriorated. Although the detailed reason for these phenomena is not yet clear, it is presumed that some difference has occurred in the adhesion of the processing solution components to the photosensitive material.

It is disclosed that an alkyl-substituted hydroxylamine is added to a color developer for light-sensitive materials such as high silver chloride color paper, and a bleaching agent having excellent biodegradability is used as a processing solution having bleaching ability. Although described in Example 1 of JP-A No. 6-161065, these are for desilvering property, edge contamination of paper, and sulfidation due to deterioration of the bleach-fixing solution, and recognition of the problem of the present invention cannot be found. Similarly, regarding processing of a photosensitive material having a magnetic recording layer, JP-A-6-95316 discloses a processing method using hydroxyl-substituted hydroxylamine as a developer, and JP-A-6-95318 discloses. A processing method using various bleaching agents is disclosed. However, all of them have a problem of photographic variation and deterioration of the processing solution, and no recognition about the influence on reading of magnetic information can be found.

Therefore, the first problem to be solved by the present invention is to provide a treatment method that does not deteriorate the adhesiveness and light discoloration of the photosensitive material after treatment even if it is treated for a long time using a material having excellent biodegradability. To do. A second problem is to provide a processing method that does not decrease the magnetic output even when a magnetic reading operation is performed on a photosensitive material having a magnetic recording layer.

The above problem has been achieved by the following method.

In a method in which a silver halide color photographic light-sensitive material for photography is processed with a bleaching solution after color development, the color developer contains at least one compound represented by the following general formula (I), A silver halide color photographic light-sensitive material which is not substantially contained and further contains at least one iron (III) complex salt of a compound represented by the following general formula (II): Processing method.

That is, 21.7 ml of water and 3 ml of 5% aqueous solution of p-octylphenoxyethoxyethoxyethane sulfonic acid soda and 5% of p-octylphenoxypolyoxyethylene ether (degree of polymerization 10) 0.5 g were put in a 700 ml pot mill. Then, 5.0 g of dye ExF-2 and 500 ml of zirconium oxide beads (diameter 1 mm) were added and the contents were dispersed for 2 hours. A BO-type vibrating ball mill manufactured by Chuo Koki was used for this dispersion. After dispersion, the contents were taken out and added to 8 g of a 12.5% aqueous gelatin solution, and the beads were removed by filtration to obtain a gelatin dispersion of the dye. The average particle diameter of the dye fine particles was 0.44 μm.

Similarly, solid dispersions of ExF-3, ExF-4, and ExF-6 were obtained. The average particle diameters of the dye fine particles were 0.24 μm, 0.45 μm, and 0.52 μm, respectively. ExF-5 was dispersed by the microprecipitation dispersion method described in Example 1 of EP549,489A. The average particle size was 0.06 μm.

For the photosensitive material processed by the above method, the adhesiveness of the photosensitive material was evaluated by the following method. In addition, light fading was also evaluated.
Adhesiveness: The sample at the end of the treatment was cut to a length of 23 cm and placed in a Fuji color negative sheet <SP roll plain / Fuji Color Sales Co., Ltd.>. Thereafter, a paper mount was applied to both sides of the negative sheet, and a weight of 1 kg / 25 cm ² was applied under conditions of wet heat (40 ° C./80%). In this state, after 4 weeks, the adhesion between the sample and the negative sheet was evaluated.
○: Level at which the sample can be quickly removed from the negative sheet and the sample is not damaged.
Δ: Adhesion between the sample and the negative sheet is slightly felt, but it can be taken out.
X: Adhesiveness between the sample and the negative sheet is strong, and a level of adhesion remains on the sample taken out.

Light fading: Concentration measurement is performed on the treated sample, and green light (G light) is obtained from the characteristic curve.
The Dmax measured in the above was read. Subsequently, the measured light-sensitive material was stored under the following conditions, and Dmax after aging was measured in the same manner. Then, the change with time of Dmax of the magenta dye was determined as follows.
Storage conditions:
Light source: fluorescent lamp / 15,000 lux / irradiation from emulsion side / 1 week Dmax change over time (ΔDmax (G))
= (Dmax before storage)-(Dmax after storage)
The results are shown in Table 2.

From Table 2, it can be seen that in the present invention, the adhesiveness after the treatment is low and the light fading is also good.

According to the present invention, it is possible to provide an excellent processing method with respect to the adhesiveness and light fading of the photosensitive material after processing, and further to the magnetic output property to the photosensitive material having a magnetic recording layer.
