PURPOSE:To enhance color reproducibility by processing a photosensitive material containing at least one of specified pyrazoazole type couplers and a compound specified in structure with a developing bath containing a compound having a specified mercapto group. CONSTITUTION:The photosensitive material containing at least one of specified pyrazoazole type magenta couplers represented by formula I is developed with a processing solution incorporating at least one of the compounds represented by formula II contained in at least one of the baths of the development processing step. In these formulae, each of Za and Zb is =C=R2 or =N-; each of R1 and R2 is H or a substituent; X is H or a group to be released by the coupling reaction with the oxidation product of an aromatic primary amine color developing agent; M is H or a cation; and Z is an N-containing heterocyclic group, thus permitting the obtained dye image to be fast and improved in stains on a white background and prevented from increasing of stains and unclearing of color even in long storage.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an image forming method using a silver halide color photographic light-sensitive material. The present invention relates to an excellent image forming method with less color staining and color staining.

(Prior art) Silver halide color photographic light-sensitive materials generally consist of a silver halide emulsion layer that is sensitive to each of the three primary colors of blue, green, and red, each of which develops colors of yellow, magenta, and cyan - so-called color reduction. The color image is reproduced using the method. Therefore, the reproduced color image largely depends on the color reduction characteristics of each layer and the spectral absorption characteristics of color development.

Generally, these properties are not necessarily the best theoretically possible due to restrictions such as color development properties of the compounds used. %, the coloring hue of the magenta coupler is important in terms of color reproduction, and various improvements have been made. Among them, pyrazoloazole magenta couplers have particularly excellent spectral absorption characteristics of color development hue.

For example, in order to improve the coloring hue of magenta couplers, in the pyrazolone series, anilino-type magenta couplers (JP-A No. 2-7-027, JP-A-44 '7-111
431 etc.) were developed. Furthermore, a pyrazoloazole type magenta coupler (U.S. % approval No. 3.
7λyo, No. 067, etc.) have been developed. This fox coupler is! - Compared to the color image obtained from a pyrazolone-type magenta coupler, there is less unnecessary absorption in the blue and red light regions, which is not only advantageous in terms of color reproduction, but the coupler itself is stable against light, heat, and humidity; Perhaps because it is difficult to decompose, it has the advantage that the resulting image has little yellowing. On the other hand, this pyrazoloazole magenta coupler is! −
Compared to pyrazolone-type magenta couplers, they have the disadvantages of increasing gray staining and causing constant temperature when the photosensitive material is stored for a long period of time before being photographed.

It is known that the compounds described in -/lJ-UO and iodine and bromine ions are effective, but it is unique to pyrazoloazole couplers such as the present invention that they are generated when the sensitive material is stored for a long time. , nothing was known about gray sting or constant temperature.

(Problems to be Solved by the Invention) Therefore, an object of the present invention is to provide a silver halide color photographic light-sensitive material that takes advantage of the advantages of pyrazoloazole-based magenta couplers and improves their shortcomings in long-term storage stability. shall be.

More specifically, the first objective is to provide a color photographic image with better color reproducibility using a magenta color image with good 1-spectral absorption characteristics. A second object is to provide a color photographic image with a robust color image and improved white background contamination. A third object is to provide a color image forming method that does not substantially cause an increase in staining or color staining even after long-term storage.

Other objects of the invention will become clear from the description below.

(Means for Solving the Problems) In order to develop a silver halide color photographic light-sensitive material that satisfies these demands, the present inventors have conducted a number of chain studies and have developed a pyrazoloazole magenta coupler. It has been found that this can be achieved by developing a photosensitive material containing a compound with a processing solution containing a specific mercapto group-containing compound.

Furthermore, chemical ripening is performed on the crystal surface to form photosensitive nuclei (Ag2S-Ag
It is also possible to use a grain structure having a so-called internal temperature type grain structure in which silver halide (n, Au, etc.) is formed and then surrounding silver halide is grown.

In the overgrowth of silver halide grain formation or physical ripening,
A cadmium salt, a zinc salt, a lead salt, a thallium salt, an iridium salt or a complex salt thereof, a rhodium salt or a complex salt thereof, an iron salt or an iron complex salt, etc. may be present.

These various emulsions may be of the surface latent scratch type in which latent images are mainly formed on the surface, or of the internal latent image type in which latent images are formed inside the grains.

Furthermore, a direct reversal emulsion may be used. The direct reversal emulsion may be of the solarization type, the internal type, the photo fogging type/nucleating agent type, or a combination of these.

In order to remove soluble silver salts from the emulsion before and after physical ripening, Niha, Tardel water washing, flocculation sedimentation method, ultrafiltration method, etc. are used.

The color photographic light-sensitive material according to the present invention is described in the aforementioned Research Disclosure, A/74 Hiro J, pages 2r to 17, and t! Development processing can be carried out by the usual methods described in the left column to right column of page 1.

The color photographic material of the present invention is usually subjected to a water washing treatment or a stabilization treatment after development, bleach-fixing or fixing treatment.

That is, color negative processing (consisting of color development, white fixing, stabilizing bath, etc.) and color reversal processing (consisting of black and white development, reversal, color development, bleaching, fixing, stabilizing bath, etc.) I can do it.

In particular, in color reversal processing, it is desirable to use a developing agent consisting of a hydroquinone derivative and a phenidone derivative in the black and white developing bath, and it is further desirable to use a silver halide solvent such as rhodan salt or sulfite. In the reversal step, a fogging agent such as a tin salt may be used, or the reversal may be performed by light irradiation.

As the bleaching bath/fixing bath, a -bath bleaching/fixing bath may be used, and a stabilizing bath may be omitted. In addition, a water washing bath (
It is preferable to provide a rinsing bath (including a rinsing bath that uses less water than a normal washing bath).

In the washing process, two or more tanks are generally used for countercurrent washing to save water. A representative example of the stabilization treatment is a multistage countercurrent stabilization treatment as described in JP-A-7-RJ-Hiroshi No. 3 instead of the water washing step. In the case of this step, a two-tank countercurrent column is required. Various compounds are added to this stabilizing bath for the purpose of stabilizing images. For example, various buffering agents for adjusting membrane pH (for example, pH 3 to t) can be cited as representative examples. In addition, water softeners (aminopolyphosphonic acid, organic phosphoric acid, aminopolyphosphonic acid, phosphonocarboxylic acid, etc.), disinfectants (benzisothiazolinones, intiazolones, ≠-
