Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The first invention of the present invention relates to a photographic oil-in-water dispersion, and more particularly to a photographic oil-in-water dispersion capable of reducing coating failure.

The second invention relates to a silver halide photographic light-sensitive material, and more particularly to a silver halide photographic light-sensitive material having improved latent image stability and capable of rapid processing.

2. Description of the Related Art A silver halide photographic light-sensitive material usually has a plurality of layers. To coat each layer, a coating solution is prepared and applied in multiple layers. To these coating solutions, water-insoluble organic compounds such as a coupler useful for photography and an ultraviolet absorber, an anti-turbidity agent and an anti-fading agent are added. These organic compounds are usually finely dispersed in the form of an oil-in-water dispersion and mixed with the coating solution. In the case of fine dispersion,
These organic compounds are dissolved in a high boiling point organic solvent or a water-insoluble polymer in an oily state, and then added to an aqueous solution containing a protective colloid such as gelatin, and finely dispersed using a surfactant. On the other hand, in the production of photosensitive materials, the occurrence of coating failures leads to a reduction in yield, so that reduction of failures such as spots and stripes is required. When the above organic compound is dissolved in an oily state, a low-boiling organic solvent is usually added as an auxiliary solvent to assist the dissolution. However, if the amount of the auxiliary solvent is large, a coating failure such as a streak tends to occur due to this, so that the low-boiling organic solvent is often distilled off.

However, as a result of examining such an oil-in-water dispersion for photography containing a small amount of a low-boiling organic solvent, a new problem has been found in that even if the dispersion is kept stagnant for a long time, the coating failure is rather increased. .

Accordingly, the present inventors have conducted various studies and found that, with an oil-in-water dispersion containing a specific compound and having a specific low boiling point organic solvent content, coating failures were small even after long-term storage. One invention was reached.

Next, the second invention will be described. Silver halide photographic light-sensitive materials are widely used because of their excellent image quality. In order to further increase the convenience, it is required to speed up the development processing. Various means for speeding up have been proposed, but the effect is great when silver halide grains having a high silver chloride content are used. However, when a silver halide emulsion having a high silver chloride content is used, if the time until post-exposure processing is short or long, the color change of the finished image tends to occur due to the time change. There was a problem.

On the other hand, antifungal agents are often added to silver halide photographic materials in order to suppress the generation of mold. For example, JP-A-59-226344, JP-A-60-131.
Various compounds have been proposed in the specification such as 532.

However, when a mildewproofing agent is used in combination with a silver halide photographic light-sensitive material containing a silver halide emulsion having a high silver chloride content, there is a large variation in color density due to the time change until the post-exposure processing. I found a new issue of becoming.

The present inventors have conducted various studies and found that the use of a specific antifungal agent resulted in a small change in color density after exposure even in a silver halide emulsion having a high silver chloride content. Reached.
