JPH0682189B2 - Silver halide photographic light-sensitive material having improved haze and yellow-stain during long-term storage - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a halogen in which the generation of yellow stain and the generation of haze (hereinafter referred to as haze) near the surface of a light-sensitive material are prevented during long-term storage after development processing. The present invention relates to a silver halide photographic light-sensitive material.

BACKGROUND OF THE INVENTION In general, silver halide color photographic light-sensitive materials are three types of silver halide color photographic emulsions which are selectively sensitized so that they have photosensitivity to blue light, green light and red light on a support. Layers are applied.

It is generally known that a dye image undergoes discoloration and fading under various storage conditions. For example, a color print has a discoloration or fading when it is stored by being exposed to light for a long time like a display in a show window of a photo studio, and it is called light discoloration. Further, as in the case of storing a color print in an album, there is discoloration and fading when it is stored in a dark place of high temperature and high humidity for a short period of time, which is called dark discoloration and fading. When a photographic product having a dye image such as the color print is used as a recording material, it is desired that the discoloration and fading be as small as possible under any storage condition in order that the dye image carried is semi-permanent. Rarely, this demand has only increased in recent years.

Further, it is generally desired that the generation of yellow stain due to light, heat, and humidity in the uncolored portion is as small as possible as in the case of fading.

Among them, as a method for improving the light discoloration fading property, JP-A-58-58
No. 209,734 and No. 58-211147, there is disclosed a layer construction technique related to a photographic layer containing a 2- (2'-hydroxyphenyl) benzotriazole type ultraviolet absorber and layers related to the layer. Proposed.

According to this method, the bright and fading of the dye image is certainly reduced, but on the other hand, the tendency of haze of the light-sensitive material during long-term storage cannot be said to be sufficiently improved. The haze described above may cause haze on the surface of some photographic light-sensitive materials when stored for a long time under severe conditions of light, heat, or humidity, for example, a decrease in the visual density of a black portion or a haze-like image. Therefore, the visual sharpness is also reduced. For example, in a color print, when haze occurs in the color print after long-term storage of the finished print in an album or the like, even if it is assumed that the dye image does not fade, it is remarkably valuable in terms of overall image quality. Is decreased, which is not preferable.

Conventionally, as a mere improvement of surface properties, for example, British Patent Nos. 1,320,564, 1,320,565, 1,320,757.
JP-A-49-5017, JP-A-51-141623, JP-A-53-57023,
Although the methods described in JP-A-54-159221 and the like can be mentioned, none of them is intended to improve haze, and therefore the improvement effect by the above method was hardly obtained.

Further, with respect to yellow stain, it cannot be said that the ultraviolet absorber and the related layer constitution technology are sufficiently effective in the case of long-term storage.

Further, as a method for reducing the generation of yellow stain due to heat and humidity in the dark, for example, Japanese Patent Publication No. 52-7344.
JP-A-57-20037 and JP-A-59-5723 disclose techniques for improvement by combination of specific couplers, but it cannot be said that the effect is particularly sufficient for long-term storage.

Further, Japanese Patent Application No. 60-148026 discloses a technique for improving haze and light-fading property by combining a fine particle powder and a specific ultraviolet absorber, but the effect is not sufficient particularly for long-term storage. In addition, the effect of preventing the generation of yellow stain was scarce.

That is, the present situation is that no satisfactory method has been found for the improvement of haze and yellow stain when the light-sensitive material after development processing is stored for a long period of time, and the improvement has been greatly desired.
