Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a silver halide photographic material, and particularly to a silver halide photographic material with improved graininess.

(Prior art) Improving graininess in silver halide photographic materials (hereinafter referred to as "silver halide sensitive materials") is an important theme, and many studies have been made to date. .

One of these is a fast-reactive coupler described in JP-A-55-62454, in which the reaction with the oxidation product of the color developing agent is fast, so that development is inhibited by the oxidation product of the color developing agent. As it becomes smaller, the amount of developed silver increases in the high exposure area, and all of the coated coupler reacts, causing the so-called grain disappearance to become less noticeable (
The graininess of the high concentration area is significantly improved. However, fast-reacting couplers have the major drawback of rapidly reacting with the oxidation products of the color developing agent, resulting in the formation of a dense dye cloud, resulting in extremely poor graininess in low-density areas. have.

To overcome this drawback, US Pat. No. 3,227,554
There is a method of improving graininess by using a so-called DIR coupler described in No. 1, or a DIR compound shown in US Pat. No. 3,632,435 in combination to make the dye cloud finer. However, this method has a major disadvantage in that the inhibitor released during development impairs the grain-improving effect of high concentration, which is an advantage of fast-reacting couplers.

British Patent No. 2,083,640 also discloses couplers which produce mobile dyes. this is,
It improves graininess by blurring the generated dye image. However, this invention essentially improves the graininess by making the sharpness inert, and has the drawback that the sharpness deteriorates in proportion to the degree to which the graininess improves.

Recently, fogging agents or development accelerators or their precursors (hereinafter referred to as rFA agents), or compounds that release residues of FA compounds during development in response to the amount of developed silver (hereinafter referred to as rFAFA compounds) have been disclosed. has been done. For example, JP-A-57-150845 describes a coupler that releases acylhydrazines, and the effect of the FA agent released upon development of one silver halide grain causes multiple surrounding silver halide grains to be released. As a result, the main effects of sensitization and contrast enhancement as well as the effect of improving graininess are obtained/at the same time. The graininess improvement effect of Shikar, Shinakara, and Shinka is mainly limited to medium and high concentrations, and graininess improvement in the visually important low concentration range is desired.

(Objective of the Invention) The object of the present invention is, firstly, to provide a silver halide sensitive material with improved graininess over the entire image density range, and secondly, to provide a silver halide sensitive material with a wide latitude, little fog, and medium-to-high image density. The object of the present invention is to provide a high-sensitivity silver halide photosensitive material with improved graininess in the low density region without reducing the graininess in the density region, and thirdly, to provide a high-sensitivity silver halide photosensitive material that is accompanied by a high silver content, a decrease in sharpness, and a decrease in sensitivity. An object of the present invention is to provide a high-sensitivity silver halide photosensitive material with improved graininess without any problems.

(Structure of the Invention) A feature of the present invention is that the support has at least one silver halide emulsion layer and contains at least one coupler that reacts with an oxidized product of a color developing agent to form a dye. In a silver halide photographic light-sensitive material, a compound that releases a fogging agent or a development accelerator or a precursor thereof in response to the amount of developed silver during development, and a compound that reacts with an oxidized form of a color developing agent but does not produce a dye. This was achieved by a silver halide photographic material characterized by containing the following.

A fogging agent or a development accelerator or their precursor (
The compound (FR compound) that releases the FA agent) will be described in detail later. Further, a compound that reacts with an oxidized form of a color developing agent but does not form a dye (hereinafter referred to as an "rND compound") will be described in detail later. In the silver halide sensitive material of the present invention, the FR compound and the ND compound are contained in the same or different layers within a photographic light-sensitive layer, which usually has a multilayer structure and contains at least one light-sensitive silver halide. be done. The FA compound can be added to any scrap as long as the FA agent released from the FR compound in response to silver development does not have a fogging effect (nucleating effect) on the silver halide grains. N
Compound D can also be added to any layer of the photographic light-sensitive layer as long as it can react with the oxidized product of the color developing agent generated during silver development and suppress dye formation. Preferably, the FR compound and N
Both D compounds are added to a light-sensitive silver halide emulsion layer containing dye-forming couplers.

It is known to those skilled in the art that when comparing the graininess of dye images of silver halide color sensitive materials at the same image density, the greater the number of dye clouds, the better the graininess. It is important to increase the number. However, in order to achieve the high sensitivity that has been in high demand in photosensitive materials in recent years, large-sized silver halide grains are required, and in order to increase the number of development starting points with these large-sized grains, a simple method High silver content not only increases cost but also deteriorates sharpness. By incorporating the above-mentioned FR compound into a silver halide sensitive material, it is possible to increase the number of development starting points for emulsions containing especially large-sized silver halide grains, thereby achieving higher sensitivity and improved graininess in the medium and high density regions. did it. The improvement in graininess in the middle and high density regions is thought to be due to the fact that the FA material release increases monotonically with the amount of developed silver, so that the development starting point increases markedly. However, in the case of a sensitive material containing an FR compound, the gradation becomes harsh, resulting in a decrease in photographing latitude, an increase in fogging, and a decrease in foot sensitivity due to this.

The effects that can be achieved by using an ND compound in combination with an FR compound in the present invention can be estimated as follows. A silver halide emulsion containing an FR compound has the following effects:
Although the development starting point increases, the generated oxidized color developing agent (hereinafter referred to as "T+") does not couple with the dye-forming coupler and is deactivated by the ND compound.
The growth of each dye cloud, which has increased in number, is appropriately suppressed, and the graininess of the dye image is improved. The graininess improvement is particularly noticeable in the low image density range, and is also observed in the medium and high density ranges. Furthermore, the gradation of the dye image becomes suitably flat and the latitude is expanded, while the so-called toe-cutting effect of the ND compound reduces the color image fogging, and the inherent sensitizing effect of the FR compound is fully exerted. It is thought that In the present invention, development is accelerated because the ND compound removes T+, and the amount of developed silver increases, so even if the conversion to a dye image is partially nullified by the ND compound, the maximum image density can be maintained. It is considered possible to maintain this. Therefore,
In the present invention, N
Although the selection of the D compound is important and also depends on the activity of the ND compound, the effects of the present invention can be obtained when a relatively large amount is used compared to the amount of photosensitive silver halide used.

It is preferable to add the FkL compound and the Nl) compound to layers other than the lowest sensitivity layer 1-.

(Operation and Effect of the Invention) A fogging agent or a development accelerator or fc is a compound (l'i) that releases their precursors during development in a manner corresponding to the development weight of the silver halide grains. The development starting point of 1 is increased.In contrast to the FB compound alone, the dye cloud generated in 1 color development grows large.
Excessive formation of each dye cloud is suppressed by the coexistence of a compound (ND compound) that does not form a dye by reacting with the oxidized product of the color developing agent.

The coexistence of the FkL compound and the NL) compound with the halogenated steel emulsion and the color-forming coupler resulted in the formation of a large number of pigments of appropriate size, resulting in deterioration of the coloring compound alone. In particular, the graininess in the low linearity region is improved, and the single graininess is improved over the entire image density region. At the same time, the gradation is appropriately flattened, the latitude is expanded, and the fog is reduced.

The photographic emulsion layer of the photographic photosensitive composition of the present invention contains a color-forming coupler, that is, an aromatic primary amine developer (for example, a 7-diamine diamine derivative, an aminophenol derivative, etc.) in a single-color development process. A compound capable of developing color through oxidative coupling may be used in conjunction with a polymer coupler latex, or may be used alone in a layer that does not use a polymer coupler latex. For example, as a magenta coupler! -Vilazolone coupler, Piraso/benzimidazole coupler, Cia/7 cetyl coumaron coupler, open chain acylacetonitrile coupler, etc. Yellow couplers include acylacetamide coupler (fJ
Examples include benzoylacetanilides and pivaloylacetanilides).

Examples of cyan couplers include s7tor couplers and phenol couplers. These couplers are preferably non-diffusive and have a hydrophobic group called a pallast group in the molecule. The coupler may be either monoequivalent or monoequivalent to silver ions.

It may also be a colored coupler that has a one-color correction effect, or a turnip 2-(so-called L)I kabu 2-) that releases a development inhibitor during development. In addition to the DIR coupler, the product of the coupling reaction is colorless and may contain a colorless D11 (coupling compound) that releases a development inhibitor.

L) In addition to the IR coupler, the light-sensitive material may contain a compound that releases a development inhibitor during development.

Two or more of the above couplers etc. can be used in the same layer in order to satisfy the characteristics required for photosensitive materials,
Of course, the same compound may be added to two or more different layers.

The photographic color formers used are conveniently selected in combination to give a gray tone.

The maximum absorption band of the cyan dye formed from the cyan color former is between about 600 and 72 Onm, the maximum absorption band of the magenta dye formed from the magenta color former is between about 200 and jrOnm, and the maximum absorption band of the cyan dye formed from the yellow color former is between about 200 and 72 Onm. Preferably, the maximum absorption band of the yellow dye formed is between about ≠00 and ulOnm.

The present invention can be used in general silver halide color photographic materials such as rt, color negative film, color paper, color positive film, color reversal film for slides, color reversal film for movies, and color reversal film for TV. In particular, when used in color negative films and various color reversal films that require high sensitivity and high image quality, remarkable effects such as improved sensitivity, improved grain size, and faster processing can be obtained.

The present invention can also be applied to black and white photosensitive materials. In particular, when used in high-sensitivity black-and-white photographic materials, ultra-high sensitivity and rapid development processing can be achieved. Furthermore, when the present invention is applied to photosensitive materials for printing, high-contrast images can be obtained through rapid processing.

The present invention can be applied to light-sensitive materials that use a single black coupler system or a mixed three-color coupler system. A detailed description of the one-way black coupler can be found in U.S. Pat. No. 3,622,622, U.S. Pat. issue.

Significant effects include speeding up processing and reducing exposure doses due to increased cost.

The present invention is also applicable to black-and-white and color light-sensitive materials for diffusion transfer methods. Either direct reversal type or negative type silver halide can be used.

The present invention is also applicable to multilayer, multicolor photographic materials having at least two different spectral sensitivities on a support. A multilayer natural color photographic material usually has at least one each of a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a night-sensitive emulsion layer on a support. The order of these skins can be arbitrarily selected according to need.

Usually, the red-sensitive emulsion layer contains a cyan-forming coupler, the green-sensitive emulsion layer contains a magenta-forming coupler, and the blue-sensitive emulsion layer contains a yellow-forming coupler, but different combinations may be used depending on the case.

The present invention is particularly advantageous in improving sensitivity when used in a light-sensitive material having at least two emulsion layers having the same color sensitivity but different sensitivities. British Patent No. 223, O Hiro! The explanation given in the above issue may be helpful, but adding an FR compound to emulsion layers other than the lowest sensitivity layer is particularly advantageous in improving sensitivity.
