Description

TECHNICAL FIELD The present invention relates to a silver halide color reversal photographic light-sensitive material, and more particularly to a color reversal photographic light-sensitive material having improved sharpness without impairing graininess.

(Prior Art) In recent years, there has been a strong demand for improvement in image quality of color photographic light-sensitive materials, and in particular, improvement in sharpness has been earnestly desired, and technically great progress has been made.

For example, as a technique for improving the graininess and sharpness, a development inhibitor that forms a dye by coupling with an oxidant of a color developing agent as described in each specification in U.S. Pat.Nos. 3,148,062 and 3,227,554. There is known a method of using a compound which releases a development inhibitor or a compound which releases a development inhibitor and does not form a dye by coupling with an oxidant of a color developing agent as described in US Pat. No. 3,632,345. A technique for further improving sharpness is disclosed in JP-A-50-46133.
JP-A-52-117122 and JP-A-53-5624, techniques for improving sharpness by providing an antihalation layer, JP-A-53-139522 and JP-A-51- It is known to use the anti-irradiation dyes described in 77327.

Furthermore, in order to improve sharpness, thinning has a remarkable effect, and thinning a layer containing silver halide grains is particularly effective. To achieve this, the concentration of the color forming dye may be increased to reduce the contents of silver halide and coupler for the increased concentration. As a technique relating to this, in the method described in U.S. Pat. No. 3,726,681, a method is known in which a coupler having a fast coupling reaction is used in a highly sensitive emulsion layer and a coupler having a slow coupling reaction is used in an insensitive emulsion layer. However, for color reversal light-sensitive materials, this technique has been found not to give as good performance as expected. The reason for this is that when a high-speed reactive coupler is used in the high-sensitivity emulsion layer, the oxidation product of the color developing agent in the low-sensitivity emulsion layer diffuses and reacts in the high-sensitivity emulsion layer, and the low-density side graininess deteriorates and the This is because the sensitivity on the density side is apparently low.

(Problems to be Solved by the Invention) Therefore, a first object of the present invention is to provide a silver halide color reversal photographic material having improved sharpness without impairing graininess.

A second object of the present invention is to provide a silver halide color reversal photographic light-sensitive material which does not impair the sensitivity on the low density side even if a coupler having a high color forming property is used in the high-sensitivity emulsion layer.

(Means for Solving Problems) The object of the present invention is to provide one or more red-sensitive silver halide emulsion layers, green-sensitive silver halide emulsion layers, and blue-sensitive silver halide emulsion layers on a support. However, at least one of the color-sensitive layers is composed of a plurality of layers having different sensitivities, and the most sensitive layer among them is a coupler having a higher molar absorption coefficient of a coloring dye than the other layers of the same color-sensitive layer. Was achieved by a silver halide color reversal photographic light-sensitive material.

In the light-sensitive material of the present invention, two or more kinds of couplers used in the emulsion layer having a high sensitivity may be mixed, and in that case, it is substantially low in comparison with the molar absorption coefficient of the coloring dye of the coupler used in the other layers. It can be used with a coupler having a low molar extinction coefficient to the extent that it does not occur. In addition, couplers that use low-sensitivity layers (hereinafter referred to as low-sensitivity emulsion layers) other than the highest-sensitivity emulsion layer also have molar absorptances not exceeding the molar absorptivity of the coloring dye of the coupler used in the highest-sensitivity emulsion layer. Can be mixed with couplers with high coefficient. The ratio of the molar extinction coefficient of the coloring dye of the coupler used in the highest sensitivity emulsion layer to the molar extinction coefficient of the coloring dye of the coupler used in the low-sensitivity emulsion layer may be greater than 1 by weight, but is preferably 1.05. Or more, more preferably 1.10 or more.

 The compounds used to make the samples are shown below.

Then, the coupler C-1 of the third layer and the coupler C-1 of the fourth layer of Sample 101 were replaced by equimolar amounts with the couplers shown in Table 1, and the coupler-to-high boiling organic solvent ratio of the fourth layer was also as shown in Table 1. Dmax3 of the cyan image in the reversal process described below.
Samples 102 to 105 were prepared in which the coating amounts of the third layer and the fourth layer were adjusted to be 2.

For each of the obtained samples, ordinary sensitometry was performed on the cyan color image of the sample which was wedge-exposed with a light source of 4800 ° K, and the MTF value and RMS value of the cyan color image were determined by the following methods. The results obtained are shown in Table 1.

MTF value; The size of the MTF value of a cyan color image at a spatial frequency of 30 lines / mm was compared by comparing the magnitude of the MTF value with white light while closely contacting the MTF measurement pattern. The larger the MTF value, the better the sharpness.

RMS value: White light is exposed using a stair wedge, and the granularity of the cyan image is exposed to red light by the conventional RMS (Root Mean Squar
e) method. As the measurement aperture, 48 μ was used and the value of RMS at a concentration of 1.0 was shown. The smaller the RMS value, the better the graininess.

The relative sensitivity is shown as a relative value when the sensitivity of the cyan image of the sample 101 is 100 based on the sensitivity obtained from the reciprocal of the exposure amount that gives the density of the minimum density plus 0.5.

The coupling reactivity of the coupler of the present embodiment is a color image obtained by mixing two kinds of couplers F and G, which give different dyes which can be clearly separated from each other, and adding them to the emulsion for color development. It can be determined as a relative value by measuring the amount of each of the pigments therein.

Maximum density (DF) max of coupler F, density D at midway
The color of F, and also for coupler G (DG) m
To express the color development of ax and DG, the ratio RF / RG of the reaction activities of both couplers is expressed by the following formula.

In other words, the emulsion containing mixed couplers is exposed to light at various stages, and several DF and DG pairs obtained by color development are made into two orthogonal axes. The coupling activity ratio RF / RG is determined from the slope of the straight line obtained by plotting.

Here, if the value of RF / RG is obtained as described above for various couplers using a constant coupler G, the coupling reactivity is relatively obtained.

In the test, the following coupler was used as the coupler G.

On the other hand, in Sample 102 in which the high-speed coupler is combined with the high-sensitivity emulsion layer, the sharpness is improved, but the graininess (RMS value) is deteriorated and the sensitivity is lowered. Sample 104 using the coupler having a high molar extinction coefficient of the present invention in place of the high-speed coupler in the 102 high-sensitivity emulsion layer can increase the sharpness without impairing the graininess and the sensitivity. Further, it can be seen that the sharpness of the sample 105 of the high-sensitivity emulsion layer 104, which does not use the high-boiling organic solvent, is further improved.

Example 2 The coupler Y-2 of the eleventh layer of Sample 101 was replaced with the coupler shown in Table 2 in an equimolar amount, and the eleventh layer was coated so that the Dmax of the yellow color image in the reversal process of Example 1 was 3.5. Samples 202 and 203 with adjusted amounts were prepared.

Table 2 shows the cyan color image, magenta color image, yellow color image MTF value, yellow image RMS value, and sensitometric result of each of the obtained samples.

The sample 202 of the present invention is improved in sensitivity of the yellow image, the sensitivity of the yellow image, the magenta image, and the sharpness of the cyan image without impairing the sensitivity of the yellow image and the graininess as compared with the samples 101 and 201. it is obvious.
