Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic material and an image forming method, and more particularly, to a black-and-white photographic material using a dye image which can be processed with a color developer containing substantially no benzyl alcohol. And an image forming method.

[0002]

2. Description of the Related Art Normally, a black-and-white photographic image is formed by processing a black-and-white photographic light-sensitive material with a black-and-white developer and forming a black-and-white image with a black image or a sepia-tone black and white image by toning. On the other hand, it is also known to obtain a black-and-white image by adjusting the filter of a multilayer color photographic material using a yellow coupler for a regular photosensitive layer, a magenta coupler for an orthophotosensitive layer, and a cyan coupler for a panchromatic photosensitive layer. However, a black-and-white image using a silver image does not save resources because silver is used for the image. The formation of a black-and-white image using a multilayer color photographic light-sensitive material has a drawback that the tone of each photosensitive layer does not completely match, so that it is difficult to obtain a well-balanced black image from a low density portion to a high density portion. . Further, a color developer using benzyl alcohol is environmentally unfavorable. Further, when a color negative film is used as a negative original, the tone of the negative original cannot be faithfully reproduced unless the photosensitive wavelength range of the color photographic light-sensitive material is in the entire visible range.

Further, when such a photographic light-sensitive material is subjected to color development processing, leuco cyan is generated, and there is a defect that a reddish dye image is formed. That is, the cyan dye formed during the color development process is sufficient to render the dye leucocyan dye-forming if the oxidation potential of the bleach-fix solution (Brix) is less than a certain minimum. It is known that it has a low electrolytic reduction potential. The sensitivity of the dye to reduction is a function of the concentration of ferric ion contained in the Brix, the pH of the Brix, and the hydrophobicity of the dispersion in which the cyan dye was formed. The formation of leuco cyan dyes is usually not a problem in the development process unless the brix is emptied and needs to be replenished. In the case of brix replenishment, the amount of ferrous ions produced to oxidize the developed silver to form silver halide when ferric ions are used is such that the significant formation of leucocyan dyes can occur there. Rise to the level. The formation of this leuco cyan dye is undesirable, since the formation of such a dye causes a noticeable reduction in cyan contrast during printing and adversely affects color reproduction. For example, in the case of a black-and-white image formed by a color developer as described in the present specification, a reddish image is formed as a result. This is because the print does not have the desired amount of cyan dye.

[0004]

SUMMARY OF THE INVENTION It is a first object of the present invention to make it environmentally friendly by treating it with a color developer substantially free of benzyl alcohol. A second object of the present invention is to form a black-and-white image that faithfully reproduces the tone of a color negative film. A third object of the present invention is to form a well-balanced black and white image while suppressing the generation of leuco cyan dye.

[0005]

The object of the present invention is to provide at least one silver halide emulsion layer on a support, wherein the silver halide grains of the silver halide emulsion layer have a silver chloride content of 95 mol. %, The silver halide emulsion layer contains a yellow coupler, a magenta coupler, and a cyan coupler, and further contains a compound represented by the general formula (I). This was achieved by an image forming method in which a silver halide photographic material was developed with a color developer substantially free of benzyl alcohol.
