Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide photographic light-sensitive material, and more particularly to a silver halide photographic light-sensitive material that can be rapidly processed.

[Background of the Invention] Generally, silver halide color photographic light-sensitive materials consist of three types of silver halide photographic materials that are selectively spectral sensitized to have sensitivity to blue light, green light, and red light on a support. An emulsion layer is coated. For example, in color negative photosensitive materials,
Generally, from the side exposed to light, a blue-sensitive emulsion layer, a green-sensitive emulsion layer,
A red-sensitive emulsion layer is coated in this order, and a bleachable yellow filter layer is provided between the blue-sensitive emulsion layer and the green-sensitive emulsion layer to absorb blue light that passes through the blue-sensitive emulsion layer. ing. Furthermore, between each emulsion layer, other intermediate layers are provided for various special purposes, and a protective layer is provided as the outermost layer. Furthermore, for example, in light-sensitive materials for color photographic paper, generally a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer are coated in this order from the exposed side. For this purpose, intermediate layers including an ultraviolet absorbing layer, protective layers, etc. are provided.

It is also known that each of these emulsion layers may be provided in a different arrangement from the above, and each emulsion layer may be provided with a photosensitive layer consisting of two layers that are sensitive to substantially the same wavelength range for each color light. It is also known to use emulsion layers. In these silver halide color photographic materials, exposed silver halide grains are developed using, for example, an aromatic primary amine color developing agent as a color developing agent, and the resulting color developing agent is oxidized. A dye image is formed by the reaction of the dye with the dye-forming coupler. In this method, phenolic or naphtholic cyan couplers, 5-pyrazolones, pyrazolinobenzimidazoles, pyrazoloazoles, indacylones or cyanoacetyls are used to form cyan, magenta and yellow dye images, respectively. Magenta couplers and acylacetamide-based or benzoylmethane-based yellow couplers are used.

By the way, in recent years in the photographic industry, in order to shorten the time required for the development process when forming the above-mentioned dye image, highly active development processes such as high pH, high temperature, and high concentration of color developing agent, etc., and simplification of the processing process have been introduced. Dairying is becoming common practice. In particular, in order to shorten the development processing time by the above-mentioned high-activity development processing, it is extremely important to improve the development speed in the color development process.

The development speed in color development is greatly influenced by both the silver halide photographic material and the color developer. Therefore, various measures have been taken to improve the development speed in color development.

As one method, it is known to use a color development accelerator when developing an exposed silver halide color photographic light-sensitive material using an aromatic primary amine color developing agent. For example, as such color development accelerators, U.S. Pat. No. 2,950,970;

Compounds described in Japanese Patent Publications No. 55-62451, No. 55-82452, No. 55-62453, No. 51-124, No. 22, Japanese Patent Publication No. 51-12422, No. 55-49728, etc. were investigated. However, most of these compounds have insufficient development accelerating effects, and even those compounds that exhibit sufficient development accelerating effects often have the drawback of producing fog, making them impractical. .

In addition, JP-A-5B-64339 describes a method of adding 1-aryl-3-viratricine having a specific structure to a silver halide color photographic light-sensitive material.
No. 144547, No. 58-50532, No. 58-50
No. 533, No. 58-50534, No. 58-50535
No. 5g-50538 discloses that 1-arylpyrazolidones are added to a silver halide color photographic light-sensitive material and processed within an extremely short development time.

However, the techniques described in these publications are not necessarily satisfactory in terms of obtaining dye images with sufficient color development speed and high color density, and there is still room for improvement.

In addition, a method of color development by increasing the pH of the color developer has been proposed, but for example, if p)I is 10.5 or more, the oxidation of the color developer will be significantly accelerated, or if an appropriate buffer solution is used. Because of this lack, the color developing solution is susceptible to pH changes, resulting in problems such as difficulty in obtaining stable photographic performance and increased dependence on processing time.

On the other hand, it is also known to accelerate development by lowering the silver bromide content of the silver halide used and increasing the silver chloride content.

It is known that high chloride silver halide emulsions can be processed more quickly than emulsions containing mainly silver bromide.

Although the method of using a high silver chloride emulsion is an effective rapid processing method, it has various problems.

Improvements have been desired because of deterioration in whiteness and uneven density caused by uneven removal of the developer during transfer from the color development bath to the bleach-fixing bath. Not only development time but also bleach-fixing time,
The above-mentioned problem is particularly likely to occur when each step of stabilization and drying is accelerated.

As a result of various studies, it was found that the configuration of the present invention enables rapid processing without deterioration of whiteness or uneven processing.

[Object of the Invention] Therefore, the object of the present invention is to provide a silver halide photographic light-sensitive material that can be rapidly processed without deterioration of whiteness or uneven processing, and a processing method for the silver halide photographic light-sensitive material. is to provide.
