Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a silver halide photographic light-sensitive material, and more particularly, the present invention relates to a silver halide photographic light-sensitive material, in which a cyan coupler that serves for dispersion stability is possessed, and the dye image formed has good long-term storage stability. This invention relates to a silver halide color photographic light-sensitive material.

In order to form a dye image using a silver halide color photographic light-sensitive material, an aromatic primary amine color developing agent is usually added to the silver halide in the exposed silver halide color photographic light-sensitive material. When the grains are reduced, they are themselves oxidized, and this oxidized product reacts with a coupler previously contained in the silver halide color photographic light-sensitive material to form a dye. Usually, couplers reproduce colors using the subtractive color method, so yellow, magenta,
Three couplers are used to form the three cyan pigments.

Each coupler is usually added to a silver halide emulsion by dissolving it in a substantially water-insoluble organic solvent with a high boiling point or in this solvent in combination with an auxiliary solvent if necessary.The basic properties required for each coupler include First of all, it has good solubility in daytime boiling point organic solvents, has good dispersibility and dispersion stability in halogenated emulsions, and does not easily precipitate, provides good photographic properties, and dye images obtained. For example, the material must have robustness against light, heat, moisture, etc. In particular, for cyan couplers, improving heat and humidity resistance (fading resistance) has become a major issue in recent years.

Conventionally known cyan couplers include 2 and 5, in which the 2- and 5-positions of the phenol are substituted with acylamino groups.
- A diacylaminophenol cyan coupler is used, for example, rice 1. Iil Patent No. 2,895゜826 Meijo, Unexamined Japanese Patent Publication No. 50-112038, No. 53-1096
30 and No. 55-163537.

Cholera 2,5-diacylaminophenol cyan couplers are frequently used because they provide cyan dye images with good dark fading resistance, but they generally have the drawback of extremely poor photochromic properties.

Therefore, as a means to improve the interchromaticity of 2,5-diacylaminophenol-based cyan couplers, it has been proposed to use a benzotriazole compound in combination, as described in JP-A-50-151149, for example. There is. However, this compound is not practical because it has a large precipitation property and is only effective for photochromicity against ultraviolet rays. It is also known to use an increased amount of an organic solvent with a boiling point of dibutyl phthalate, which has been conventionally used. Although this improves the interchromaticity slightly, photographic properties such as color tone etc. Problems arose, such as giving a negative impression to the image and deteriorating the fading property. Japanese Patent Application Publication No. 5
Publication No. 7-173835 discloses that a 2,5-diacylaminophenol cyan coupler substituted with a phenol 0) 2-position chaorthosulfonamide phenylacylamide group is used in a high boiling point organic solvent having a special dielectric constant. A method has been proposed to improve the color tone and fastness of the dye by dispersing the cyan dye, but it has been confirmed that this method significantly impairs the interphotochromaticity of the cyan dye image.

The first object of the present invention is to form a dye image that has improved light resistance, heat resistance, and moisture resistance in a well-balanced manner, and exhibits excellent image storage stability over a long period of time even at high temperatures and humidity. - To provide silver halide photographic materials.

A second object of the present invention is to provide a chromogenated photographic light-sensitive material that has improved colorfastness without deteriorating fading resistance of cyan dye images.〇The present invention A third object of the present invention is to provide a silver halide photosensitive material capable of forming a dye image with improved image storage stability without adversely affecting photographic properties. The fourth purpose is to contain a cyan coupler dispersed using a high-boiling organic solvent that can be dispersed extremely stably,
Therefore, it is an object of the present invention to provide a silver halide photographic material in which cyan coupler has good dispersion stability and does not cause precipitation failure.

The present inventors have discovered that in a silver halide photographic material having at least one silver halide emulsion layer provided on a support, a cyan coupler represented by the following general formula (1) is contained in the silver halide emulsion layer. It has been discovered that the above object can be achieved by dispersing and containing at least one of Ta.
