Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for processing silver halide color photographic materials, and more particularly to a stable and rapid processing method.

(Prior Art 2) In general, in silver halide color photographic materials, after image exposure, a dye image is formed by a series of photographic processes whose basic steps are a color development step and a desilvering step.

In the above-mentioned color development step, a dye image corresponding to the image source is formed by a coupling reaction between the oxidized color developing agent or the coexisting color coupler, and at the same time, reduced silver is produced. Conventionally, various methods have been proposed in order to speed up the color development time. Among these rapid processing methods, the most preferred technique is a technique in which a 3-virazolidone derivative represented by the general formula [I] is added to a color developing solution or incorporated into a silver halide color photographic light-sensitive material, as disclosed in British Patent No. 1,032. No. 925, 1,057,87
No. 5, JP-A-57-144547, JP-A-57-49
) No. 195, etc. However, the 3-pyrazolidone derivative represented by the following general formula [I], which is known as a black-and-white developer, does not work well in an alkaline color developer.
It is stable, and it is desired to improve this stability. In commonly used black and white developers, a large amount of sulfite is used for the purpose of preserving the 3-pyrazolidone derivative, or in color developers, the use of a large amount of sulfite causes a decrease in color density, making it impractical. In addition, HO+0, which is known as a black and white developer such as hydroxylamine 84 conductor and hydroquinone, ascorbic acid, p-amine phenol, etc.
=O+nOH.

A technique of adding HO+0=O+nNR,R1 to a color developing solution is proposed in Japanese Patent Application Laid-open No. 153437/1983.

However, even when this technique is used, the color density decreases, and the effect of preventing changes in the photographic properties of the color developer over time is weak and cannot be put to practical use.

In addition, even when the above-mentioned 3-pyrazolidone derivative is added to the sensitive material, it elutes and accumulates in the color developer during color development.
Even a small amount can have a significant effect on photographic properties, posing a serious problem. Further, when processing at a high temperature of 30° C. or higher, there is a problem that staining due to the 3-pyrazolidone derivative is likely to occur due to its high development activity.

(Object of the Invention) The present invention has been made to solve the above-mentioned problems, and the first object is to provide long-term stable photographic processing in the presence of a 3-pyrazolidone derivative represented by the following general formula [I]. It is an object of the present invention to provide a rapid processing method for developing a silver/10-silver-genide color photographic light-sensitive material, which provides the following characteristics. The second objective is to develop a method for processing silver halide color photographic materials that causes less unnecessary staining caused by the 3-pyrazolidone derivative represented by the following general formula [I] even when processed at high temperatures of 30°C or higher. It is about providing.

Samples of the color paper subjected to stepwise exposure were processed according to the processing steps of Example-1 before and after storage for one week at 38° C. for each continuous color development processing solution.

The yellow, magenta, and cyan densities of the above-mentioned developed sample were measured using PDA-65. J' is shown in Table 2.Furthermore, Table 2 shows the results of Yep-Stein measurements on the developed samples after storage in the solution.

Table 2 As is clear from the above Table 2, the developer solution A1,2 also contains the 3-pyrazolidone derivative [I-4] of the general formula [I] according to the present invention. The additive compounds are pear and/or hydroquinone, whose concentration decreases greatly due to storage, and yellow stain is also high, making it unsuitable for practical use.

However, developer &3 containing the non-reducing polyhydroxy compound of the present invention has a small decrease in density and yellow stain, and even when the 3-pyrazolidone derivative of the present invention is contained in a light-sensitive material, it is extremely low. It turns out that it is effective.
