DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material and an image forming method, and more particularly, to a silver halide color photographic light-sensitive material which has excellent image storability, color developability, image stability after processing, and rapid processing and scanning exposure. The present invention relates to a silver halide color photographic material having excellent image forming properties.

[0002]

2. Description of the Related Art Silver halide color photographic light-sensitive materials have been attached to albums or the like, or placed in a photo stand or the like for appreciation, and image storability in both dark places and bright places is desired. I have.

JP-A-63-38932, JP-A-63-1230
No. 47 describes image forming couplers, which are currently in general use. However, these couplers do not have sufficient image storability, especially in a dark place where no light is exposed, and further improvement is desired.

Further, there is a problem that an image is not stabilized immediately after a specific developing process and drying, and the image is not stabilized for an extremely short time, and improvement thereof is desired. Also,
From the viewpoint of improving the productivity in the development processing, the color developing properties (maximum density Dm, gradation γ) of the color coupler occupy an important position, and are particularly brought about when the processing is performed with a processing solution in which running is repeated. There is a demand for an improvement in the decrease in the coloring property.

On the other hand, as a means for improving the productivity in the development processing, a method of shortening the processing time has been used.
The couplers described in JP-A-38932, JP-A-63-123047 and the like do not have sufficient coloring properties in a treatment in which the treatment time is extremely shortened, and improvement is desired.

[0006] Laser exposure has been put to practical use in order to improve productivity and enable digital processing. Laser exposure is performed with extremely intense light in a short period of time, and photographic photosensitive materials are required to have excellent color developability even when exposed to such intense light.

[0007] However, it has been found that when the exposure is performed under such severe exposure conditions, sufficient performance cannot be obtained with the known coupler.

Further, JP-A-63-250648 and JP-A-6-130596 disclose a technique for improving image storability by combining a water-insoluble and organic solvent-soluble polymer with a specific yellow color coupler. Have been. However, the polymer described in the above-mentioned patent is not sufficiently effective in improving the image storability of a specific yellow coupler, and further improvement is desired.
