Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, it is capable of rapid processing, saves silver, has excellent storage stability, and has light resistance (resistance to light). The present invention relates to a silver halide color photographic light-sensitive material capable of obtaining color images with good fastness. In general, silver halide color photographic light-sensitive materials have three types of photographic silver halide emulsion layers selectively sensitized to have sensitivity to blue light, green light, and red light, coated on a support. For example, in silver halide photographic light-sensitive materials for color negatives, a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer are generally coated in this order from the exposed side. A bleachable yellow layer is provided between the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer to absorb the blue light that passes through the blue-sensitive silver halide emulsion layer. A single layer of filter is provided. Furthermore, each emulsion layer is provided with another middle layer for various special purposes, and a protective layer as the outermost layer. Furthermore, for example, in a silver halide photographic light-sensitive material for color photographic paper, generally from the side to be exposed to light, a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a blue-sensitive silver halide emulsion layer are formed in this order. Silver halide photosensitive material for color negatives: As in 1, intermediate layers such as an ultraviolet absorbing layer, a protective layer, etc. are provided for each special purpose. It is also known that each of these silver halide emulsion layers is provided in a different arrangement from the above, and furthermore, each silver halide emulsion layer is sensitive to substantially the same wavelength range for each color light. It is also known to use a photosensitive silver halide emulsion layer consisting of two 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 reaction of the product with the dye-forming coupler. In this method, phenolic or naphtholic cyan couplers, 5
- Pyrazolone, pyrazolinopenzimidazole, pyrazolotriazole, indacylon or cyanoacetyl magenta couplers and acylacetamide yellow couplers are used. These dye-forming couplers are contained in the light-sensitive silver halide emulsion layer or in the developing solution.The present invention uses halogenated couplers in which these couplers are non-diffusible and previously contained in the silver halide emulsion layer. This invention relates to silver color photographic materials. In recent years, there has been a demand in the industry for silver halide color photographic materials that can be processed rapidly, save silver, have excellent shelf life, and provide color images with good light fastness. There is. In other words, silver halide color photographic light-sensitive materials are processed in automatic processing machines installed in each laboratory, but as part of an effort to improve service to users, processing is carried out within the same day on the day when processing is received. It is required that the image be developed and returned to the user.
Recently, it has become necessary to return items within a few hours of receiving them, and there is an urgent need to develop silver halide color photographic materials that can be processed more rapidly. Furthermore, it is a matter of course that silver halide color photographic materials that can be processed quickly are required to be able to save silver and be economically provided at low cost, and also to be able to be stored raw for a long period of time. However, it is also very natural that a silver halide color photographic light-sensitive material is desired which provides stable photographic properties and color images that are fast to light. The present invention relates to a technique that satisfies the above requirements regarding a magenta color image forming coupler. [Prior Art] In the past, most of the magenta color image-forming couplers that have been widely put to practical use and have been studied are 5-pyrazolones. Dyes formed from 5-pyrazolone couplers have excellent fastness to heat and light, but 430
Unnecessary absorption having a yellow component exists in the vicinity of nm, causing color turbidity. A pyrazolobenzimidazole core is described in British Patent No. 1,047,812 as a magenta imaging coupler core that reduces this yellow component, and U.S. Pat.
, 770,447, and the pyrazolotriazole bone core described in Patent No. 3.725.0137 are known. [Problems to be Solved by the Invention] Among these, the dye formed from the IH-pyrazolo[3,2-CI-s-triazole type coupler described in the above-mentioned U.S. Pat. In a solvent such as ethyl or dibutyl phthalate, there is little unnecessary absorption near the 43On layer, and the sharp cut property on the long wavelength side is also excellent, but the fastness of the formed azomethine dye to light is extremely low. This significantly impairs the performance of color photographic materials, especially print-type color photographic materials. The above-mentioned pyrazolotriazole magenta coupler is one of the main technologies for silver saving.While the pyrazolotriazole magenta coupler has advantages such as good color reproducibility, it has poor color development and is difficult to process quickly. It also has the disadvantage of being difficult to apply. On the other hand, as one of the techniques for enabling rapid processing, a method is known in which a precursor of a color developing agent is incorporated into the photographic constituent layers of a silver halide color photographic light-sensitive material. As described above, silver halide color photographic light-sensitive materials containing color developing agent precursors can be rapidly processed; however, if a pyrazolone magenta coupler is used, for example, the color developing agent precursor decomposes during storage. It reacts with a color developing agent to produce magentastin. However, when a pyrazolotriazole-based magenta coupler is used, magentastin is less likely to occur due to its low reactivity at the pH in the film during storage, but it could not be completely prevented. The present invention has been developed in view of the above, and is a magenta color that can be rapidly developed, has excellent color development, completely prevents the occurrence of magentastin, has excellent shelf life, and is light-fast. A technical problem is to provide a silver halide color photographic material from which images can be obtained. [Means for Solving the Problems] The silver halide color photographic light-sensitive material of the present invention which solves the above-mentioned technical problems has a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, In a silver halide color photographic light-sensitive material having a photographic constituent layer consisting of a red-sensitive silver halide emulsion layer and another hydrophilic colloid layer, the green-sensitive silver halide emulsion layer has a compound represented by the following general formula [I]. containing at least one compound (hereinafter referred to as the pyrazolotriazole magenta coupler of the present invention),

The inventor of the present invention has conducted intensive research to solve the above-mentioned technical problems, and as a result has found the following. That is, the pyrazolotriazole magenta coupler of the present invention has good optical properties, but has the disadvantage that it is inferior to pyrazolotriazole magenta couplers other than the present invention in terms of color development.
