2. Description of the Related Art In recent years, digitization of plate making and printing processes, C
With the progress of computer-to-plate (TP), the need for DDCP (direct digital color proof) is rapidly increasing. A typical system of DDCP is laser sublimation thermal transfer, sublimation thermal transfer, ink-jet method, and a silver halide color photosensitive material containing a direct positive silver halide emulsion and a coupler is treated with an aromatic primary amine developer having a specific structure. A method of obtaining a coloring dye close to the printing color by a coupling reaction has been put to practical use. However, there is a problem in quality, price, productivity, etc. of each method, none of them satisfy all of them, and they have not yet reached widespread use. Among them, the silver proof color photographic color proof method is one of the features that a color image similar to a printing color can be obtained relatively easily and inexpensively, and that no waste material is generated. It is. On the other hand, DDCP is generally required to have the following performance. 1) Color reproducibility as close as possible to printing ink is obtained. 2) High productivity and output samples can be obtained in a short time. 3) High resolution. 4) Stable quality is always obtained. 5) Inexpensive. However, DDCP using a conventional silver halide color photograph directly processed with a positive silver halide emulsion and an aromatic primary amine developer having a specific structure has the following problems. 1) The hue difference from the printing ink is large. 2) Whiteness is not sufficient in whiteness. 3) The development time is long. With the aging of the developer, tar is likely to be generated, which causes a problem such as attachment to the photosensitive material. Therefore, using a quick negative emulsion,
DDCP using a more stable developing agent has been demanded. However, in order to reproduce a color similar to a printing color in combination with a conventional coupler technology, 4-amino-N
It was essential to use a developing agent having no substituent on the phenyl group represented by -ethyl-N- (β-hydroxyethyl) aniline (hereinafter referred to as T-32). However, when T-32 is oxidized, it has a problem in stability such that oxidized products react with each other and easily become tar, there is a problem that tar adheres to a sample during processing, and the problem is The formulation of the solution was restricted, and the use of a large amount of antioxidant sulfite was required. Was an obstacle. On the other hand, 4-amino-3-methyl-N- having a substituent on the phenyl group
(Β-hydroxyethyl) aniline (hereinafter referred to as CD-4) and 4-amino-3-methyl-N-ethyl-N- (β-methanesulfonamidoethyl) aniline (hereinafter CD) widely used for color paper -3)
Although these problems are extremely small, the hue of the dye obtained by the reaction between the developing agent and the coupler is inferior to T-32 in reproducing a printing color, and is substituted with a phenyl group represented by CD-3. It has been required to realize a silver salt-based DDCP capable of reproducing a printing color with a stable developer having a group.

In the present invention, the shorter the processing time of the desilvering step, the more remarkable the effect of the present invention, and the time of the desilvering step is 2 minutes or less, more preferably 1 minute or less. The silver halide color photographic light-sensitive material used in the present invention is generally subjected to washing and / or stabilization after desilvering such as bleach-fixing. The amount of rinsing water in the rinsing process can vary widely depending on the characteristics of the photosensitive material (for example, the material used such as a coupler), the application, the rinsing water temperature, the number of rinsing tanks (number of stages), the replenishment method such as countercurrent, forward flow, and other various conditions. Can be set. this house,
The relationship between the number of washing tanks and the amount of water in the multi-stage countercurrent method is described in the Journal of the Society of Motion,
Picture and Television Engineers (Journalof the Society of
Motion Picture and Televi
Sion Engineers) Vol. 64, p. 248
253 (May 1955). Usually, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 4.

According to the multistage countercurrent system, the amount of washing water can be greatly reduced, for example, 1 l or less, preferably 0.5 l or less per m ^{2 of the} photosensitive material, and the effect of the present invention is remarkable. Due to an increase in the residence time of water in the inside, bacteria proliferate, and there arises a problem that the generated suspended matter adheres to the photosensitive material. In the processing of the color light-sensitive material of the present invention, Japanese Patent Application No. 61-131 discloses a solution to such a problem.
The method for reducing calcium and magnesium described in No. 632 can be used very effectively. Further, chlorinated fungicides such as isothiazolone compounds and thiabendazoles described in JP-A-57-8542, chlorinated sodium isocyanurate described in JP-A-61-120145, and described in Japanese Patent Application No. 60-105487. Benzotriazole, copper ion and others, Hiroshi Horiguchi, "The chemistry of antibacterial and antifungal agents", edited by the Sanitary Technology Society, "Sterilization, disinfection, and antifungal technology of microorganisms". The bactericide described in "" can also be used. Further, in the washing water, a surfactant as a draining agent and a chelating agent represented by EDTA as a softening agent can be used.

It is possible to carry out the treatment with the stabilizing solution directly after the washing step or without the washing step. A compound having an image stabilizing function is added to the stabilizing solution, and examples thereof include an aldehyde compound represented by formalin, a buffering agent for adjusting a membrane pH suitable for stabilizing a dye, and an ammonium compound. Further, in order to prevent the growth of bacteria in the liquid and impart fungicidal properties to the processed photosensitive material, the above-mentioned various bactericides and fungicides can be used. Further, a surfactant, an optical brightener and a hardener may be added. In the processing of the light-sensitive material of the present invention, when stabilization is directly performed without going through a washing step, a method disclosed in
No. 543, No. 58-14834, No. 60-22034
All known methods described in No. 5, etc. can be used.

In addition, 1-hydroxyethylidene-1,
It is also a preferable embodiment to use a chelating agent such as 1-diphosphonic acid or ethylenediaminetetramethylenephosphonic acid, or a magnesium or bismuth compound. Also, by using a multi-stage countercurrent system as in the case of washing water, the flow of water can be greatly reduced (1 l or less, more preferably 0.5 l or less). The replenishment of the washing water or the stabilizing solution may be continuous or intermittent. In the latter case, it is performed according to the processing amount or at regular intervals. The pH of the washing step or the stabilizing step of the present invention is 4 to 10, preferably 5 to 8. The temperature can be variously set depending on the use and characteristics of the photosensitive material, but is generally 15 to 45 ° C, preferably 20 to 40 ° C. The time can be set arbitrarily, but the shorter the time, the more remarkable the effect of the present invention is, and it is preferably 30 seconds to 2 minutes, more preferably 30 seconds to 1 minute 30 seconds. It is preferable that the replenishing amount is small from the viewpoints of running cost, reduction of discharge amount, handleability, and the like, and the effect of the present invention is large.

The specific amount of replenishment is 0.5 to 50 times, preferably 3 to 40 times the amount brought in from the previous bath per photosensitive material and unit area. The liquid used in the washing and / or stabilizing step can be used in the previous step. As an example of this, the overflow of the washing water reduced by the multi-stage countercurrent method is caused to flow into a bleach-fixing bath as a preceding bath, and the bleach-fixing bath is replenished with a concentrated solution to reduce the amount of waste liquid. In the present invention, the total time of the bleach-fixing step and the washing or stabilizing step is preferably 3 minutes or less.

In the present invention, in particular, the inclusion of bromide ions or iodide ions in the bleach-fixing solution prevents image unevenness that occurs when entering the bleach-fixing solution from the developing solution, and provides high quality halftone dots. It is very excellent in that an image can be obtained. The preferable addition amount of bromide ion is 1 × 10 ⁻² to 2 mol per liter, and the preferable addition amount of iodide ion is 5 × 10 ^{−4 to} 5 × 10 ⁻² mol. Particularly preferred is 1/10 to 1 mole of bromide ion.
