DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide light-sensitive material, and more particularly to a silver halide emulsion containing a diffusion-resistant coupler for forming a diffusion-resistant dye in a silver halide emulsion. The present invention relates to a silver halide color photographic material which forms a color image by processing with a color developing solution containing a developing agent and then processing with a processing solution having bleaching ability.

2. Description of the Related Art Conventionally, photographically useful water-insoluble reagents such as oil-soluble couplers, antioxidants used for preventing fading, color fogging or color mixing (eg, alkylhydroquinones, alkylphenols, chromans, cumarones) ), Hardeners, oil-soluble filter dyes, oil-soluble UV absorbers, oil-soluble optical brighteners, DIR compounds (for example, DI
R hydroquinones, colorless DIR couplers), developers, dye developers, DDR redox compounds, DDR couplers 、 are dissolved in suitable oil-forming agents, ie, high boiling solvents, to form hydrophilic organic colloids, especially gelatin. Used in a state dispersed in the presence of a surfactant in a solution in a hydrophilic organic colloid layer (for example, a photosensitive emulsion layer, a filter layer, a back layer, an antihalation layer, an intermediate layer, and a protective layer). Can be As the high boiling point organic solvent, a phthalate compound or a phosphate compound is generally used.

[0003] Phthalic acid ester compounds and phosphate ester compounds, which are high boiling organic solvents, have an effect on the affinity with colloids such as gelatin, the dispersibility of couplers, the stability of color image formation, and the effect of color image formation. It has been widely used because of its excellent properties such as influence on hue, chemical stability in photosensitive materials and availability at low cost. However, these known high-boiling organic solvents (e.g., phthalic acid ester compounds and phosphoric acid ester compounds) are not suitable for light-sensitive, heat- and humidity-sensitive color images in recent photosensitive materials which are required to have high performance. However, the effect of preventing discoloration and generation of stains was still insufficient. As described above, various requirements are imposed on the high boiling point organic solvent used in recent photosensitive materials. For example,
It can be easily obtained or manufactured at low cost, has excellent solubility and dispersion stability of photographic reagents, has no adverse effect on developability and photographic properties, has excellent safety and has no environmental impact, It is a general requirement that the photosensitive material be excellent in thermal stability and, in the case of a color photosensitive material, be excellent in the effect of preventing fading of a color image.

In a color light-sensitive material, a dye formed from a coupler, particularly a pyrazoloazole-based magenta dye or a pyrroloazole-based cyan dye, easily associates in a film film, and has a maximum absorption wavelength of absorption by the associated body. Is different from that of the dye monomer. As a result, if the absorption by the aggregate is too large, it is not preferable in color reproduction. In addition, if the maximum absorption wavelength of the dye can be adjusted to a longer wavelength or a 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 color light-sensitive material with better color reproduction can be manufactured at a low cost. It can be provided at the manufacturing cost.

In order to solve such a problem, the maximum absorption wavelength of each of yellow, magenta and cyan dyes is reduced and increased in a high-boiling organic solvent which can be a dispersion medium such as a dye-forming diffusion-resistant coupler. It has been found that some compounds have an effect of changing the absorption waveform by suppressing or accelerating the association of a dye, and have attracted attention. For example, urea compounds of EP 0309158 A1, EP 030
9160A1 amide compound and the like. However, in these compounds, in general, it is often difficult to make the hue of the pigment preferable and to improve the solubility and dispersion stability of the material required when used as a dispersion medium, In many cases, the color-forming property of the dye-forming, diffusion-resistant coupler was lowered. Also,
When the above compound was used in the same layer as the dye-forming diffusion-resistant coupler, the discoloration of the dye formed from the coupler due to heat, humidity and light often deteriorated. In particular, the deterioration of the discoloration of such dyes due to heat, humidity, and light is caused by the above-mentioned EP 0309158 A1 and EP 0309160.
A urea compound and an amide compound having a hydrogen atom on a nitrogen atom described in A1 etc. were remarkable when used in the same layer as the dye-forming diffusion-resistant coupler. Further, Japanese Unexamined Patent Publication No.
No. 2248 describes urethane compounds as anti-fading agents, but they have no effect of changing the hue.
Further, the compatibility with couplers and the like was poor, and thus it was not suitable for use as a high boiling point organic solvent.

[0006]

The 0.1 g / m ² -1 to 0.05 g / m ^2, the compound S-2 according to the present invention 0.05 g / m ² In addition, also,
In the fifth layer, a high boiling organic solvent Solv-2 (dibutyl phthalate) 0.08 g / m ² was added to the compound S according to the present invention.
After the imagewise exposure, a sample prepared in the same manner as in Example 1 except that the weight was changed to
No. 59249, Processing No. 1 of Example 1. When the treatment was carried out at 18, the increase in the minimum density due to the residual color of the sensitizing dye and the like was suppressed.

[0105]

As described above, the silver halide light-sensitive material of the present invention has an effect of being excellent in solubility and dispersion stability of a photographic reagent. Further, since the silver halide light-sensitive material of the present invention is configured as described above, when used for color photography, the solubility and dispersion stability of the photographic reagent are excellent, and the color reproducibility of the dye is excellent. There is no fading, and the dye-diffusion-resistant coupler has an effect of being excellent in color development.
