Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a silver halide color photographic light-sensitive material, and more specifically, to uneven film sagging, liquid storage stability, sulfide precipitation, pollution load, stain after processing and liquid storage. The present invention relates to a method for processing a silver halide color photographic light-sensitive material having improved properties.

2. Description of the Related Art Generally, a silver halide color photographic light-sensitive material is subjected to image development, color development processing, bleaching, fixing or bleach-fixing processing, which has fixing ability, and then stabilization, washing, etc. Is processed by. In the water washing step following the treatment with the processing solution having the fixing ability, thiosulfate which is a compound which reacts with silver halide to form a water-soluble complex salt, other water-soluble silver complex salt, and further as a preservative It is known that the sulphite, metabisulphite, etc. are contained in, adhered to, and brought into the light-sensitive material, and when the amount of washing water is small, the image storability is adversely affected.

Therefore, in order to eliminate such drawbacks,
In reality, a large amount of running water is used to wash away the salt from the light-sensitive material. However, in recent years, there is a demand for a treatment process in which the amount of washing water is reduced and pollution measures are taken for economic reasons such as shortage of water resources, soaring sewerage charges and utility costs, and pollution reasons.

Conventionally, as a countermeasure against these problems, for example, a method in which a water washing tank has a multi-stage structure and water flows countercurrently is described in West German Patent 2,92.
0,222 and S.R.Gold Basser (SRGol
dwasser), "Water Flow Rate in Immersion-Washing
of Motion-picture Film) ”SMPTE, Vol.64,248
Pp. 253, May (1955), etc.

There is also known a processing method in which a preliminary washing with water is provided immediately after the fixing bath to reduce the pollutant components contained in and attached to the light-sensitive material and entering the washing step, and to reduce the amount of washing water.

However, these techniques are not treatment methods that do not use washing water at all. Therefore, in recent years, when water resources are exhausted and the cost for washing is increasing due to price increase of crude oil and the like, it is becoming a serious problem.

On the other hand, there is also known a processing method in which a stabilization process is carried out immediately after photographic processing without washing with water. For example, a silver stabilizing treatment with a thiocyanate described in US Pat. No. 3,335,004 is known. However, this method has a drawback that a large amount of inorganic salt is contained in the stabilizing bath, so that the surface of the light-sensitive material is stained after drying.

When these stabilizing treatments are carried out,
It has also been found that there is another drawback associated with degradation of the dye image during long term storage.

On the other hand, when processing a color photographic light-sensitive material for photography represented by a photographic light-sensitive material in which the silver halide is silver iodobromide, a stabilizing bath containing formalin is generally used in the final processing step following the washing bath. Has been.

The formalin used in the stabilizing bath prevents the physical properties of the color photographic light-sensitive material, especially the occurrence of scratches on the surface of the color photographic light-sensitive material and the change in gradation due to the photographic light-sensitive material being gradually hardened over time. Has the effect of
Further, it is known that it is also effective for the deterioration of the stability of the dye image due to the unreacted coupler remaining in the color photographic light-sensitive material.

However, formalin, which is added to the stabilizing bath for the purpose of stabilizing the dye image, adheres to the light-sensitive material and forms an adduct with sulfite ion brought in from the previous bath (processing solution having fixing ability). However, not only the effect of stabilizing the dye image, which is the original purpose, is reduced, but there is also a drawback that the sulfurization is promoted. To solve these problems, it has been proposed to use an alkanolamine as shown in U.S. Pat.No. 4,786,583, but the use of the alkanolamine tends to adversely affect the unexposed yellow stain.
Moreover, the sulfidation preventing effect was not sufficient.

Regarding formalin, in the United States,
CIIT (Chemical Industry Association Toxicology Research Institute) has formalin 15
It has been announced that ppm has caused nasal cancer in rats,
NIOS (National Institute of Occupational Safety and Health), ACGI
H (Industrial Hygiene Government Specialist Council) also said that cancer may occur. Even in Europe, formalin is strongly regulated, and in West Germany, formalin has been regulated to 0.1 ppm or less in homes for 10 years.

Further, in Japan, formalin has harmful effects on mucous membranes due to stimulating action on deleterious substances, drugs on drugs, regulations on organic solvent poisoning according to labor safety law special regulations or regulations on household products, regulations on fibers and plywood. Since 1975, the Ministry of Health and Welfare has newly introduced formalin regulation for underwear and baby clothes, and a technology that can reduce formalin has been long sought.

Further, in recent years, Process C-41 developed by Eastman Kodak Company for the purpose of speeding up treatment and saving bath.
Processes for color negative films called B and C-41RA are known. This treatment consists of (color developing step)-(bleaching step)-(fixing step)-(stabilizing step)-(drying step), and is a rapid processing which is substantially not washed with water.
Stabilizer used in this stabilizing process (stabilizer),
Further, as an alternative technique of formalin, for example, JP-A-63-244036
JP-A-62-27742 and JP-A-61-151538, it has been known to use hexamethylenetetramine compounds and hexahydrotriazine compounds. However, these hexamethylenetetramine-based compounds and hexahydrotriazine-based compounds have the effect of suppressing fading of the dyes, but the fixing solution and the bleach-fixing solution are subsequently treated with a stabilizing solution without using washing water. At that time, it was found that the stabilizing solution drips onto the back surface of the light-sensitive material, especially the photographic film, and uneven sagging of the film easily occurs. Furthermore, when the treatment liquid is used for a long period of time, especially when the number of treated liquids is small, the above-mentioned formalin substitute is used and the stable liquid is sulphidized and treatment stains are generated even though the formalin is not used. I knew that.

Particularly when the replenishing amount of the stabilizing solution is small,
This failure becomes a serious problem that cannot be ignored.

[0016]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve the stability of film sagging unevenness and the stability of sulfide precipitates in the stabilizing solution and the resulting stain of processed light-sensitive materials. Further, it is an object of the present invention to provide a method for processing a silver halide color photographic light-sensitive material, which can eliminate the use of formaldehyde contained in a processing solution for the above effect and improve the pollution load.

Stabilization of dye images and suppression of stains are possible without using formaldehyde, and the sag unevenness of the film base surface, which is a drawback of using these compounds,
