Abstract

PURPOSE:To obtain a high-sensitivity photosensitive material which has improved sharpness, picture keeping quality, and graininess of a leg part by incorporating a specific diffusion resisting compound in a nonphotosensitive intermediate layer. CONSTITUTION:Plural silver halide emulsion layers which have substantially the same color sensitivity, but differ in photographic sensitivity are formed on a base, and a photosensitive layer containing a diffusion resisting coupler which forms diffusion resisting coloring pigment by reacting with oxidized bodies of principal chemicals of coloring development is also formed on the base to obtain a silver halide photosensitive material. Then, the nonphotosensitive intermediate layer is provided adjacently to a silver halide emulsion layer having the highest photographic sensitivity among the plural layers on the base side. Further, the diffusion resisting coupler which forms mobile coloring pigment coloring in the same hue with the diffusion esisting coloring pigment by causing coupling reaction with oxidized bodies of principal checmicals of coloring development is incorporated in this nonphotosensitive intermediate layer. Consequently, the photosensitive material which has high sensitivity and provides good gradations while its sharpness, picture keeping quality, and graininess of the leg part are improved is obtained by using a small amount of silver.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a silver halide photographic material, and more specifically, a silver halide photographic material with improved photographic properties such as sensitivity, graininess, sharpness, storage stability, and gradation. Regarding.

There has been a strong demand for the development of highly sensitive and fine-grained photosensitive materials, which are referred to as halogen photosensitive materials (referred to as photosensitive materials), and for this reason, many improved photosensitive materials, especially color Photosensitive materials have been proposed.

As one of the light-sensitive materials for the above-mentioned purpose, for example, British Patent No. 923.045 discloses a high-sensitivity emulsion layer containing a diffusion-resistant coupler that develops substantially the same hue;
Sensitivity can be increased without deteriorating graininess by separately coating a silver rognide emulsion layer with the same color sensitivity as a low-speed emulsion layer and adjusting the maximum coloring density of the high-speed emulsion layer to a low value. states.

However, in recent years, color light-sensitive materials for photography, in particular, have been required to have increasingly high sensitivity, and the silver emulsion layer contains coarse silver oxide with coarse graininess and/or couplers with high coupling speed. are forced to use it. Therefore, the above British patent No.! The method of No. 923,045 was found to be insufficient in improving the graininess, and further efforts have been made to improve the graininess.

For example, on page 4 of Japanese Patent Publication No. 49-15495, it is stated that graininess can be improved by providing a gelatin layer between the high-sensitivity emulsion layer and the low-sensitivity emulsion layer. Although this method improves the graininess in the low density region, it has a significant negative effect on the gradation, and in order to restore the gradation, conventional techniques, such as increasing the grain size of silver halide and forming a low-speed emulsion layer, are used. If the sensitivity is increased, the graininess in the middle density range, which is particularly important in practice, deteriorates, which is undesirable. Furthermore, the multilayer color photosensitive material having the above structure also has the disadvantage that the stability of the color image density deteriorates against changes in development processing conditions, such as pH value, temperature, time, etc. There is.

Furthermore, for example, JP-A No. 57-155536 discloses that between the high-sensitivity emulsion layer and the low-sensitivity emulsion layer, a color is developed which has substantially the same hue as that of the diffusion-resistant coupler contained in the high-speed and low-sensitivity emulsion layers. , and the coupling speed is much higher than that of the diffusion-resistant coupler contained in the high-sensitivity emulsion layer.By providing a non-photosensitive hydrophilic colloid layer containing the diffusion-resistant coupler, graininess and gradation can be improved. It is said that it can be improved. Although this method does not cause gradation failure and improves graininess, it is still insufficient in improving graininess in the low to medium density range.

Furthermore, for example, in the above-mentioned Japanese Patent Publication No. 49-15495 and Japanese Patent Application Laid-open No. 53-7230, medium-sensitivity silver halide emulsion layers with low color density are provided between the high-sensitivity emulsion layer and the low-sensitivity emulsion layer, respectively. A method is described in which the layer contains a compound (referred to as a DIR compound) capable of reacting with the oxidized form of a color developing agent and releasing a diffusion-inhibiting substance. However, these methods have drawbacks such as an increase in capri as the amount of silver halide used increases and the use of valuable silver resources.

In addition, in light-sensitive materials having two or more μg silver emulsion layers with the same color sensitivity, higher photosensitivity is usually achieved.
The L-coating layer improves graininess by lowering the coupler density (in this case, the oxidized form of the developing agent generated from the development reaction diffuses over a wide area in search of a partner for the coupling reaction, resulting in large particles with low concentration). However, the oxidized product of the developing agent produced by the development of silver halide in a silver halide emulsion layer with a relatively high sensitivity is It diffuses not only within the layer, but also into adjacent or adjacent silver halide emulsion layers with higher coupler density and lower sensitivity, forming a conspicuous granular dye cloud there.

As a result, when viewing the light-sensitive material, the developed silver grains of the silver halide emulsion layer, which has a much higher sensitivity, are affected even in the problematic density (or photosensitivity) range, resulting in a disadvantage that the graininess deteriorates. .

Therefore, the purpose of the invention is to provide a light-sensitive material with high sensitivity, good gradation, and improved sharpness, image storage stability, and leg graininess, and which requires less silver usage. .

As a result of various studies conducted by the present inventors, the above purpose was achieved by forming a plurality of silver emulsion layers on a support with substantially the same color sensitivity but different sensitivities. It has been done,
A photosensitive material having at least one photosensitive layer containing a diffusion-resistant coupler that reacts with an oxidized form of a color developing agent to form a diffusion-resistant coloring dye, wherein the plurality of...
Among the silver halide emulsion layers, at least the highest sensitivity
- A non-photosensitive intermediate layer (referred to as an intermediate layer according to the present invention) is provided adjacent to the support side of the silver halogenide emulsion layer, and the non-photosensitive intermediate layer further contains an oxidized form of a color developing agent. We have discovered what can be achieved with a light-sensitive material containing a diffusion-resistant coupler that can undergo a coupling reaction to form a mobile color-forming dye that develops substantially the same hue as the diffusion-resistant color-forming dye. did.

That is, the present invention proposes a novel and improved photosensitive material and attempts to solve the above-mentioned problems.

Hereinafter, the photosensitive material of the present invention will be explained in more detail.

Below, in explaining the present invention, one aspect of the present invention will be explained. That is, in the present invention, for example, photosensitive layers with different photosensitivity are sandwiched between the intermediate layer according to the present invention, that is, a high-sensitivity silver halide emulsion layer (hereinafter referred to as a high-sensitivity emulsion layer) and a low-sensitivity silver halide emulsion. (hereinafter referred to as a low-speed emulsion layer).

In this case, the high-sensitivity emulsion layer and the low-sensitivity emulsion layer may each be one layer, but if they are two layers, the effects of the present invention can be further enhanced as described in the British Patent No. 923. (It is preferable that the effect of the method described in No. 145 is added to the acidification effect. Also, in the present invention, it is preferable that the high-sensitivity emulsion layer is provided apart from the support from the low-sensitivity emulsion layer. When each layer has a structure of two or more layers, it is preferable that the layer closer to the support is a layer with lower sensitivity.

In addition, for the speed difference between the high-speed emulsion layer and the low-speed emulsion layer, the optimum cold point can be determined by a well-known method, taking into consideration gradation and graininess, but generally it is about 0.1 to 0.1. 1. Olog E
It is preferable to have a difference in (E; exposure amount).

Further, the high-speed emulsion layer and the low-speed emulsion layer have substantially the same color sensitivity, and after color development processing, the two emulsion layers contain coloring dyes having substantially the same hue. It is preferred to contain diffusion-resistant couplers that can be formed.

Further, the intermediate layer according to the present invention has a dry film thickness of 0.2μ to 2μ.
．． It is preferable to form a film in the range of 0μ.

As used herein, the word diffusion resistant @ has the meaning normally applied in photosensitive materials, and for all practical purposes the photosensitive materials of the invention are prepared in an alkaline atmosphere, preferably at a pH of 10. When processed in the above media, it refers to the property of not moving or wandering through an organic colloid layer, such as a gelatin layer.

In addition to the diffusion-resistant coupler capable of producing the mobile coloring dye according to the present invention (hereinafter referred to as the uninvented coupler), K and other diffusion-resistant couplers 2 - Hydroquinone rust for regulating the progress of development It can contain conductors, colorless couplers, fine particles, silver rognide, etc. Moreover, the intermediate layer can also be composed of two or more layers.

Generally, light-sensitive materials containing couplers include a red-sensitive silver halide emulsion layer containing a diffusion-resistant cyan color-forming coupler, a green-sensitive emulsion layer containing a magenta color-forming coupler, and a yellow color-forming coupler. However, in the present invention +C, "substantially the same color sensitivity" means having a light-sensitive area in substantially the same spectrum region, and red, green, and blue-sensitive emulsion layers, respectively. This is in a broad sense indicating the three divisions of the back, and slight spectral changes are considered to be substantially the same. Furthermore, in the photosensitive material according to the present invention, remarkable effects according to the present invention 1c are observed in each of the red-sensitive, green-sensitive, and blue-sensitive layers, but
It is preferable that at least the green-sensitive layer exhibits the aspect of the present invention, and if the aspect of the present invention is applied to all layers, the image quality of the final color image will be even better.

The coupler of the present invention has an amino group at the coupling position that immobilizes the coupler and makes it diffusion resistant, and at the non-coupling position, it has a mobility of the coloring dye generated by the coupling reaction with the oxidized product of the color developing agent. It has a regulatory group for control. When the coupler couples with the oxidized form of the color developing agent, the stabilizing group is released and the resulting color dye becomes mobile.

The "mobility" of the "diffusion-resistant coupler capable of forming a mobile coloring dye" according to the present invention means that the coloring dye produced when the diffusion-resistant coupler undergoes a coupling reaction with the oxidized form of a color developing agent is It refers to the degree of mobility that allows movement within the layer in which it is contained. Such mobility can be controlled by modulating groups on the couplers described above. The modulating group depends on the coupler nucleus to which it is attached, other substituents present on the coupler, and the color developer used.

As mentioned above, the light-sensitive material of the present invention is composed of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different light sensitivities on a support, and has color development. It has at least one photosensitive layer containing a diffusion-resistant coupler that reacts with an oxidized form of a developing agent to form a diffusion-resistant coloring dye, and further comprises at least one light-sensitive layer containing a diffusion-resistant coupler that reacts with an oxidized form of a developing agent to form a diffusion-resistant coloring dye; An uninvented intermediate layer is provided adjacent to the support side of the silver halide emulsion layer, which has at least the highest photosensitivity, and the intermediate layer further undergoes a coupling reaction with the oxidized form of the color developing agent to form the above-mentioned It contains a diffusion-resistant coupler that can form a mobile color-forming dye that develops substantially the same hue as the diffusion-resistant color-forming dye.

The effect of the present invention is achieved by such a light-sensitive material, and although this effect is not clearly understood, when the light-sensitive material is subjected to color development after exposure, the silver halide emulsion layer having the highest photosensitivity is prevention of deterioration of sharpness and graininess of an adjacent silver halide emulsion layer with lower photosensitivity due to an excessively formed oxidized color developing agent;
Furthermore, the gradation properties are also controlled, and at the same time, due to the coupling reaction between the above-mentioned uninvented ``diffusion-resistant coupler capable of forming a mobile coloring dye'' and the above-mentioned oxidized color developing agent, the above-mentioned It is believed that the generation of a mobile coloring dye in the intermediate layer according to the present invention makes it possible to more clearly improve the graininess of the legs.
