Description

TECHNICAL FIELD The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, it achieves high sharpness by reducing the dry film thickness.
The present invention also relates to a silver halide color photographic light-sensitive material in which the obtained cyan dye image has improved color recovery, processing stability and storage characteristics.

[Prior art]

In a silver halide color photographic light-sensitive material, particularly a silver halide photographic light-sensitive material for a color negative, a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer are generally arranged in this order from the exposed side. It has been painted,
Usually, a bleachable yellow filter layer is provided between the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer to absorb blue light transmitted through the blue-sensitive silver halide emulsion layer. Has been.

Furthermore, an intermediate layer is provided between the emulsion layers, and a protective layer is provided as the outermost layer. It is also known that each of these light-sensitive silver halide emulsion layers is provided in an arrangement different from that described above. Further, as each silver halide emulsion layer, light-sensitivity to each color light in substantially the same wavelength range is obtained. It is also known to use a photosensitive silver halide emulsion layer having two or more layers having different properties and different sensitivities. In these silver halide color photographic light-sensitive materials, cyan,
To form magenta and yellow dye images,
A coupler is used.

Among the recent light-sensitive materials, on the one hand, there is a strong demand for higher image quality from the user, and on the other hand, the progress of the small format is seen, and a light-sensitive material having a particularly high sharpness is required.

 Especially in the case of a silver halide emulsion layer closer to the support,
Thinning by reducing the amount of inder is an effective way to improve sharpness.
It is known to be a dan (eg Journal of the O
ptical Society of America58(9), 1245-1256 (196
8), Photographic Science and Engineering16
(3), 181-191 (1972), etc.).

Further, as specific means therefor, it is known that the coating amount of gelatin is simply reduced, the coating amount of coupler is reduced, the amount of high boiling point solvent for dispersing the coupler is reduced, and so-called polymer couplers are used. However, these methods are not preferable in terms of photographic performance.

For example, simply reducing the gelatin film thickness in the photosensitive layer causes phenomena such as aggregation and destruction of the high boiling point organic solvent as a coupler solvent in the coating film, which results in crystallization of the coupler or oil. Since a "sweating phenomenon" in which droplets ooze out onto the surface of the photosensitive material occurs, it has not been put to practical use.

Further, reducing the amount of coupler used generally leads to a decrease in color density.

On the other hand, from the viewpoint of accelerating development processing, the tendency toward higher processing temperatures and shorter processing times has become stronger in recent years.Therefore, especially in color light-sensitive materials using conventional naphthol cyan couplers, The shortening of the bleaching process or the bleach-fixing process of developed silver has a serious drawback in that a large amount of ferrous iron causes reduction fading of the cyan dye.

As a coupler which does not cause the reduction fading of such a cyan dye, for example, a phenolic coupler having an ureido group at the 2-position described in JP-A-56-65134 is known, but it has been known in the recent bleaching process. In terms of speeding up, improvement in reduction fading of the cyan dye is not sufficient, and in the thinning of the gelatin film to improve the sharpness described above, performance fluctuation due to changes in color development processing step increases, It has been found to have serious drawbacks.

[Problems to be solved by the invention]

Therefore, the present invention provides a halogen which is excellent in sharpness, does not cause the fading of the dye in the bleaching process of the cyan dye image or the bleach-fixing process, and has improved stability and storage stability against changes in the color development process.
