Description: BACKGROUND OF THE INVENTION The present invention relates to a silver halide photographic light sensitive material (hereafter abbreviated to light sensitive material) and a method for development processing said material, particularly to a light sensitive material having excellent fastness of an obtained dye image, stability of the image, stability of characteristics after storage, adaptability to rapid processing, and stability of characteristics in the case of rapid processing, and a method for development processing said material. A silver halide photographic light sensitive material has been employed as a material to provide a high quality image with stable quality and low cost. Requests for high quality and stable quality by the user is demanded more and more. With reference to the request for high image quality, improvement of color reproduction, reproduction of gradation and sharpness etc. is requested. As for the stable quality, it is necessary to improve stability in manufacturing, fastness during long time storage as unexposed status and characteristics change depending processing condition. Further, high fastness of the obtained image is desired. In response to the request for high image quality, in recent years, pyrazolotriazole type magenta dye forming couplers have been employed to improve color reproduction. Pyrazolotriazole type magenta dye forming couplers have a problem as the dye produced by the couplers is unfavorable in fastness against light. Improvement has been investigated in both coupler and dye image stabilizer, for example, a pyrazolotriazole type magenta coupler substituted by secondary or tertiary alkyl etc. disclosed in Japanese Patent O.P.I. Publication Nos. 61-65245, 61-120146, 61-120147, 61-120148, 61-120149, 61-120150 and 61-120151; phenol or phenylether compounds disclosed in Japanese Patent O.P.I. Publication Nos. 56-159644, 59-125732, 61-145552, 60-262159 and. 61-90155; amine compounds disclosed in Japanese Patent O.P.I. Publication Nos. 61-73152, 61-72246, 61-189539, 61-189540 and 63-95439 are listed. However problems arise by employing these techniques, for example, deterioration of film property of photographic composing layer because of an increase of oil-soluble component in the layer, deterioration of the image quality when stored for long time, increasing fluctuation of photographic properties such as sensitivity, gradation and fog caused by storage of unexposed light sensitive material, since the structure of the dye forming coupler is complicated and the molecular weight is large, and a large amount of oil-soluble additive must be employed. While it is effective in improving these problems to increase an amount of gelatin as the binder in the photographic constitution layer, it also results in a lowering in the development processing speed, contrary to the demand for rapid processing properties. For a photographic light sensitive material such as colored paper, particularly employed in direct appreciation it is desired to see a print picture of stable equality immediately, and therefore rapid processing of development processing and reducing quality fluctuation dependent on development processing is desired. For this purpose, a method wherein the development tank is a slit type, a method of coating or spraying a developing processing composition or to a surface of the light sensitive material or a method of heating the light sensitive material just before the development processing have been provided. These methods are effective in rapid processing and reducing fluctuations depending on change in developing condition. However, it has been made clear that fluctuations of characteristics such as sensitivity and fog increases may be caused by storage before exposure when the light sensitive material employs the pyrazolotriazole type magenta dye forming coupler. SUMMARY OF THE INVENTION The present invention has been made in consideration of the situation mentioned above, and the object of the invention is to provide a silver halide photographic light sensitive material which is excellent in color reproduction and improved in image storability, particularly image stability under light exposure.

For the silver halide photographic light-sensitive materials, it is advantageous to use gelatin as a binder.

The support used in the color light sensitive material of the invention may be any material, and includes papers covered with polyethylene or polyethylene terephthalate, paper supports made of natural or synthetic pulp, a polyvinyl chloride sheet, polypropylene containing a white pigment, polyethyleneterephthalate support and baryta papers. A support comprising a paper and a water-proof resin layer provided on each side thereof is preferable. The water-proof resin preferably is polyethylene, polyethyleneterephthalate or their copolymer. As white pigments to be used for the support, inorganic and/or organic white pigments can be used. The preferred are inorganic white pigments. For example, sulfatesof alkaline earth metals such as barium sulfate, carbonate salts of alkaline earth metals such as calcium carbonate, silicates such as fine silicate and synthetic silicate, calcium silicate, alumina, alumina hydrate, titanium oxide, zinc oxide, talc and clay are cited. The preferred white pigments are barium sulfate and titanium oxide. The amount of white pigment contained in the water-proof resin layer on the surface of the support is preferably not less than 13% by weight, and more preferably not less than 15% by weight, in view of improved image sharpness. The degree of dispersion of white pigment in the water-proof resin layer on a paper support used can be measured by means of a method described in Japanese Patent O.P.I. Publication No. 2-28640. When measured by means of this method, the degree of dispersion of white pigment is preferably not more than 0.20, and more preferably not more than 0.15 in terms of fluctuation coefficient described in the aforesaid Publication, in view of improved glossiness. The average roughness of center surface of the support is preferably 1.05 µm or less, more preferably 0,12µm or less because of improved glossiness. The white pigment containing water-proof resin layer of a paper support or hydrophilic colloid layer coated on a paper support preferably contains a bluing agent or reddening agent such as ultramarine or oil-soluble dyes in order to adjust a reflective density balance of white background after processing and to improve whiteness. After the surface of the support is provided with corona discharge, UV ray irradiation and firing treatment if necessary, a light-sensitive material may be coated directly or through subbing layers (one or two or more subbing layers in order to improve adhesiveness, anti-static property stability in sizing, anti-abrasion property, stiffness, anti-halation property, abrasion property and/or other properties of the surface of the support.) When a light-sensitive material is coated using silver halide emulsions, a thickener may be used. As coating methods, an extrusion coating method and a curtain coating method is especially advantageous because they can coat 2 or more layers concurrently. The invention is applied to preferably a light sensitive material containing no color developing agent, and more preferably a light sensitive material capable of forming an image for direct appreciation. The example includes color paper, color reversal paper, a light sensitive material capable of forming a positive image, a light sensitive material for display and a light sensitive material for a color proof. The invention is applied to especially preferably a light sensitive material having a reflective support. As a developing apparatus used for developing the silver halide photographic light-sensitive material of the present invention, a roller transportation type in which a light-sensitive material is sandwiched by rollers provided in the processing tank to be conveyed or an endless belt type in which the light-sensitive material is fixed on a belt.

When a light-sensitive material is processed in a large amount, it is conventional to conduct running processing using an automatic developing machine. In this occasion, the smaller the replenishment amount of the replenisher composition the better. The most preferable processing style from the viewpoint of environmental friendliness is to add a replenishing composition in the form of a replenishing tablet. A method disclosed in Published Technical Report No. 16935/1994 is the most preferable. EXAMPLES The present invention is explained based on examples.
