Abstract

PURPOSE:To improve color reproducibility and lightness reproducibility by lowering the average silver iodide content of the silver halide particles of the higher sensitivity layer of two layers having the same color sensitivity lower than the average silver iodide content of the other layer and incorporating a DIR compd. into one layer of photograph constituting layers. CONSTITUTION:At least one of the photograph constituting layers including at least the two silver halide emulsion layers which are different in the color sensitivity consists of at least the two layers which are the same in color sensitivity. The silver halide particles of the layer having the highest sensitivity of these two layers is formed to the average silver iodide content lower than the average silver iodide content of the silver halide particles in the other layer; in addition, the DIR compd. is incorporated into at least one of the photograph constituting layers. The DIR compd. is the compd. which eliminates a development restrainer or the compd. capable of releasing the development restrainer by reaction with the oxidant of a color developing main agent. The color reproducibility is improved in this way and the lightness reproducibility is improved as well.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a reversal silver halide photographic light-sensitive material, and in particular, it has improved color reproducibility and brightness reproducibility. This relates to silver photographic materials.

[Background of the invention]

Reversal silver halide photographic materials are required to have various performances, but in response to recent demands for higher image quality, improvement in color reproducibility has become particularly important.

In the case of reversal silver halide photographic light-sensitive materials, the development effect is mainly used because it is practically impossible to correct the secondary absorption of coloring dyes using colored couplers such as those used in color negatives. That is, development of silver halide in one emulsion layer has been achieved by utilizing an interimage effect (hereinafter referred to as 11E) that suppresses development of other layers.

For example, the most common development inhibiting substance is Yoma ion, and IIE can be achieved by controlling the Yoma ion in silver halide emulsions layer by layer, or by adjusting the silver iodide content on the surface and inside of silver halide grains. There are known techniques to strengthen the

Further, JP-A-51-51941 discloses hydroquinone derivatives that release organic inhibitors.

All of the above techniques attempt to control IIE in the first development. However, the above-mentioned means of increasing IIE in the first development in color reversal processing, that is, in black and white development, is generally ineffective and, for example, in the case of increasing the silver iodide content, desilvering defects and staining in the second development tend to occur. Various negative effects such as these caused problems, and the results did not necessarily lead to great effects. In addition, these methods of controlling IIE in the first development are based on a mechanism in which one emulsion layer suppresses the development of other layers, so although the color purity increases, the brightness of the color image decreases. However, there was a major problem in that the brightness balance with the achromatic color portion of the screen was greatly disrupted, giving an unnatural brightness reproduction.

On the other hand, attempts to obtain a multilayer effect in color development, ie, second development in reversal processing, are also known. For example, JP-A No. 61-84646 discloses a technique for obtaining IIE by diffusing an oxidized scavenger of a color developing agent into other layers to suppress the color density of the other layers. This technique has many favorable points because it does not have a large adverse effect on the first development, but the effect is not great and compared to conventional IIE
There is a need for technology that increases the

[Purpose of the invention]

Accordingly, an object of the present invention is to provide a reversal silver halide photographic material that has excellent color reproducibility and improved brightness reproducibility.

[Structure of the invention]

The above object of the present invention is to provide a reversal silver halide photographic light-sensitive material having a photographic constituent layer including at least two silver halide emulsion layers having different color sensitivities for forming a dye image on a support. At least one of the silver emulsion layers is composed of at least two layers having the same color sensitivity, and among the at least two layers, the silver halide grains in the layer with the highest sensitivity are the same as the silver halide grains in the other layers.

Two-color reproducibility was evaluated by the range of variation in sensitivity to green light and magenta. That is, the green light density of the obtained sample was 1.5
The sensitivity value given was read and the sample sensitivity difference between green light exposure and magenta light exposure was expressed as the difference IIE with respect to sample 1 (1 ogE unit, E is the exposure amount).

The larger this difference is, the more sensitive the response is to green-magenta light, the larger the IIE, that is, the higher the saturation of green, and the better the color reproducibility.

Further, magenta exposure and white exposure were provided using a magenta filter and an ND filter having the same bidicore density. The visual density value of the magenta filter-exposed image at the exposure amount corresponding to the visual density of 1.0 in the obtained white-exposed image was defined as the brightness reproducibility. This value is 1
The closer it is to , the smaller the brightness balance between magenta and achromatic colors, and the better the brightness reproduction can be obtained.

The evaluation results of these two types are shown in Table 2.

Margin Table 2 Below Table 2 As can be seen from Table 2, only the present invention realizes brightness reproduction of magenta color that has high saturation and is more faithful to achromatic colors.

g Water was added (pH-6, 5) Color reproducibility was evaluated by the range of variation in sensitivity to red light and cyan light. That is, the red light reflection density of the obtained sample was 1.0.
Read the sensitivity value that gives the sample sensitivity difference between red light exposure and cyan light exposure, and calculate the difference in sample sensitivity between sample 15 and 11 Ei+ (lo
It is expressed in gE units (E is exposure amount).

The larger this difference is, the more sensitive the response is to red-cyan light, the larger the IIE, that is, the higher the saturation of red, and the better the color reproducibility.

Additionally, a cyan filter and an ND filter with the same visual density were used to provide cyan exposure and white exposure. Visual density 1 of the obtained white exposure image
．． The visual density value of the cyan filter exposed image at the exposure amount corresponding to 0 was taken as the brightness reproducibility. The closer this value is to 1, the smaller the balance of brightness between cyan and achromatic colors is and the better the brightness reproduction can be obtained.

The evaluation results of these two types are shown in Table 4.

Table 4 As can be seen from Table 4, only the present invention enables expression with high chroma and more faithful reproduction of brightness.
