Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a silver halide photographic light-sensitive material, which has particularly excellent dark fading resistance, suppresses the occurrence of fog during storage over time, and has excellent suitability for rapid processing. This invention relates to silver halide color photographic materials.

[Background of the Invention] Silver halide color photographic materials are produced by reducing exposed silver halide grains with a color developing agent, and the oxidized product of the color developing agent and yellow, magenta, and cyan dyes produced at this time. Those capable of obtaining a dye image by coupling with a coupler that forms are commonly used.

Cyan couplers that are widely used to form the cyan dye are phenolic and naphthol cyan couplers. In particular, phenolic cyan couplers are widely used as cyan couplers that form cyan dye images that can be viewed directly, such as those used in color photographic papers. The performance required for such a phenolic cyan coupler is that the cyan dye formed first has good spectral absorption characteristics, that is, the absorption in the green region of the absorption spectrum (particularly from soon to 550 nm) is small. and the maximum absorption wavelength is long wavelength (640 nm to 66 nm)
0nm), and second, the cyan dye formed has sufficient fastness against light, heat, and moisture, and under these storage conditions, there is little contamination in the uncolored area. Thirdly, it has good coloring properties and provides sufficient coloring sensitivity and coloring density, and fourthly, bleaching baths or bleach-fixing baths containing EDTA ferric salt as a main component do not become fatigued by long-term use. The dye loss is small even when the dye is used.

Various cyan couplers have been proposed as cyan couplers that meet such required performance, but among them, two
2 substituted with an acylamino group at position and an alkyl group at position 5
-Acyl-5-alkylphenol cyan coupler, 2,5- substituted with acylamino group at 2- and 5-positions
Diacylaminophenolic cyan couplers are particularly preferred cyan couplers. For example, equity [[49-11572, U.S. Pat. No. 2.772]

These 2-acyl-5-alkylphenol cyan couplers and 2,5-diacylaminophenol cyan couplers have excellent fastness of the cyan dye images formed, especially resistance to fading in the dark, and they also have excellent resistance to fading in the dark. It is particularly advantageous in that there is almost no dye loss even when treated with bleach or bleach-fix solutions.

On the other hand, in recent years, in this industry, rapid processing is possible,
There is a demand for silver halide color photographic materials (hereinafter referred to as color photosensitive materials) that have high image quality, excellent processing stability, and low cost.In particular, silver halide color photographic materials that can be processed quickly Color photographic materials are desired.

In other words, silver halide photographic materials are subjected to running processing in automatic processing machines installed at each processing laboratory, but as part of an effort to improve service to users, processing is carried out on the same day that the development is received. In recent years, it has even become necessary to return the product within a few hours of receiving it, and the development of silver halide color photographic materials that can be processed more quickly is becoming more and more important. It's urgent.

In general, such dye image formation involves processing a color photosensitive material that has been exposed to light through color development processing, bleaching processing, and fixing. ! l!
The color photographic paper is processed by processing (or bleach-fixing) and then washed with water. In particular, color photographic paper, which requires rapid processing, has the greatest technical advantage of shortening the color development process.

As a means of shortening the color development process, it is possible to use a precursor of a color developing agent when developing an exposed silver halide color photographic light-sensitive material using an aromatic primary amine color developing agent.

No. 28, JP-A No. 58-200233, Research Disclosure No. 15159, Research Disclosure No. 12146, etc. have been studied, and it has become possible to obtain a development accelerating effect.

However, in color photosensitive materials using the above-mentioned color developing agent precursors, the color developing agent precursors diffuse during storage of undeveloped photosensitive materials over time, and fog and staining may occur during color development processing.

Oxidation-reduction potential -70mV The reflection density of the cyan coloring dye of the treated sample was measured using a Sakura color densitometer POA-60 model (manufactured by Konishiroku Photo Industry Co., Ltd.).
Fog density was obtained by measuring using a red filter with a bottom. The results are shown in Table 1.

(Rapid processing suitability test) After each sample was subjected to wedge exposure according to a conventional method, the color development process time for the above processing step was 1 minute 30 seconds, 2 minutes 30 seconds, and 3 minutes 30 seconds, and cyan was processed at each step. The maximum anti-tJJm degree (expressed as DRmax) of the coloring dye was measured using the above-mentioned densitometer. The results are shown in Table 1.

Cyan dye image storage test in the dark) Each sample was exposed to wedge light according to a conventional method, and then developed in the same way as the fog test during storage over time. After storage for 2 weeks at 77° C. and 70 RH in the dark, the residual concentration at an initial concentration of 10 was measured.

From the results in Table 1 above, it can be seen that the cyan coupler according to the present invention has a high boiling point 8 expressed by the general formula [1[III] of the present invention.
