Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material excellent in color reproducibility.

[0002]

2. Description of the Related Art Conventionally, photographically useful reagents which are poorly soluble in water (eg, oil-soluble couplers, antioxidants used for preventing fading, color fog or color mixture (eg, alkylhydroquinones, alkylphenols, chromanes, coumarones). ), A hardener, an oil-soluble filter dye, an oil-soluble ultraviolet absorber, an oil-soluble optical brightener, a DIR compound (for example, DI
R hydroquinones, non-colored DIR couplers), developing agents, dye developing agents, DDR redox compounds, DDR couplers} are suitable oil formers, ie, soluble in high-boiling solvents, hydrophilic organic colloids, especially of gelatin. Used as a dispersion in the presence of a surfactant in a solution in a hydrophilic organic colloid layer (eg, photosensitive emulsion layer, filter layer, back layer, antihalation layer, intermediate layer, protective layer) To be As the high boiling point organic solvent, a phthalic acid ester compound or a phosphoric acid ester compound is generally used.

The phthalic acid ester compounds and phosphoric acid ester compounds, which are high-boiling point organic solvents, have dispersibility of couplers, affinity with colloids such as gelatin, influence on the stability of color image, and color image. It has been widely used because of its excellent effects on hue, chemical stability in light-sensitive materials, low availability, and the like.

However, these known high-boiling point organic solvents (for example, phthalic acid ester compounds and phosphoric acid ester compounds) are used for light-sensitive materials of recent years which are required to have high performance. It was still insufficient in terms of the effect of preventing discoloration and stain generation due to the above.

As described above, various requirements are imposed on the high-boiling point organic solvent used in recent light-sensitive materials. For example, it can be easily obtained or manufactured at low cost, it has excellent solubility and dispersion stability of photographic reagents, it does not adversely affect developability and photographic properties, it has excellent safety and does not affect the environment. It is a general requirement that the color image has an excellent anti-fading effect and the chemical stability is excellent.

By the way, there is a dye formed from the coupler that causes association in the film film, and the maximum absorption wavelength of absorption by the associated product is different from that of the dye monomer. Too much absorption by the aggregate is not preferable for color reproduction. If such a problem can be adjusted by making the maximum absorption wavelength of the dye longer wavelength or shorter wavelength by an additive or the like used in the same layer as the dye without changing the structure of the dye itself, a silver halide which is more preferable for color reproduction. A color photographic light-sensitive material can be provided at a low manufacturing cost.

In order to solve such a problem, the maximum absorption wavelength of each of the yellow, magenta and cyan dyes is made shorter and longer in an organic solvent having a high boiling point which can be a dispersion medium such as a dye-forming diffusion resistant coupler. It has been found that some of them have the effect of suppressing or promoting the association of dyes and changing the absorption waveform, and thus, they are attracting attention. For example, phosphine oxides, phosphinic acid esters, phosphonic acid esters of JP-A-63-301941, JP-A-2-4239, ureas of EP 0309158A1, sulfonamides of EP 0309159A1, and EP 0309160A1. No. amides and the like.
However, in these compounds, it is often difficult to satisfy both the requirement of the hue of the dye and the improvement of the solubility and the dispersion stability of the materials required when used as a dispersion medium. In many cases, the resulting dye-forming diffusion-resistant coupler has a reduced coloring property.
Further, when the above compound was used in the same layer as the dye-forming diffusion resistant coupler, the color fading of the dye formed from the coupler due to heat, humidity and light was often deteriorated.

(Preparation of Samples 2 to 23) When preparing an emulsified dispersion of the fifth layer coating liquid, the coupler and the high boiling point organic solvent in Sample 1 were used as the coupler and the high boiling point organic solvent shown in Table 13. Further, for the sample 2, the high boiling point organic solvent is used in an amount of 2 times, and the samples 3 to 14, 16, 17, 19,
For 20, 22, and 23, the compounds shown in Table 13 were added in the same amount as the high boiling point organic solvent. Thereafter, a coating liquid was prepared in the same manner as in Sample 1, and coating, exposure, and development were performed to prepare Samples 2 to 23. At this time, the amount of coupler used was equimolar to C-21 in Sample 1. As a comparative compound, CS-

[0115]

[Chemical 38]

(Evaluation of Sample) The absorption spectrum of each sample after the treatment was measured with a spectrophotometer (Shimadzu UM365). The magnitude of the absorbance at 600 nm when the absorbance at the maximum absorption wavelength is normalized to 1 is D _{600 nm} ,
It was used as a measure of the size of the meeting. The smaller the value of D _600nm ,
Represents a small meeting. The maximum color density (D _max ) of each sample after treatment was also measured using red light. Table 13
The values of D _{600 nm} and D _max of each sample are shown in FIG.

[0117]

[Table 13]

The results shown in Table 13 show the following. As is clear from the comparison between Sample 1 and Samples 3 to 14, So
It can be seen that when a sulfoxide or sulfone compound is added to lv-3, the value of D _600nm becomes small and the association is suppressed. Further, as is clear from the comparison between Samples 3 to 7 and Samples 8 to 14, when a sulfoxide or sulfone compound other than the present invention is added, the value of D _max becomes small and a sufficient color density cannot be obtained. When the sulfoxide or sulfone-based compound of the present invention was added, the value of D _max was larger than that when it was not added, and it can be seen that good color developability is obtained.
