Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material containing a novel cyan dye-forming coupler.

(Prior Art) When a silver halide color photographic light-sensitive material is exposed to light and then subjected to color development, an oxidized aromatic-amine developer and a dye-forming coupler react to form a color image. Generally, in this method, a subtractive color reproduction method is used, and in order to reproduce blue, green, and red, images of yellow, magenta, and cyan, which are complementary colors, are formed, respectively. Phenol derivatives or naphthol derivatives are often used as couplers to form cyan images. In color photography, color-forming couplers are added to the developer solution, light-sensitive photographic emulsion layer, or other color 1'J! It is built into the mold and forms a non-diffusible color, g, by reacting with the oxidized product of the color developer formed by development.

(Problems to be Solved by the Invention) Phenols or naphthols are often used as cyan image forming couplers.

However, several problems remain with respect to the storage stability of color images obtained from conventionally used phenols and naphthols and the color development properties of these couplers. For example, U.S. Patent Nos. 2.561531, 2.369.92
No. 9, No. 2,424730 and No. 2.801,17
The color images obtained from the 2-acylaminophenol cyan couplers described in U.S. Pat.
95.826 and U.S. Pat. No. 4.533.999, U.S. Pat.
The color images obtained from the 5-acylamino-2-ureidophenolic cyan couplers described in No. 4, No. 4, No. 554, No. 244, etc., generally have poor light fastness.

1-Hydroxy-2-
Naphthamide cyan couplers generally have good color development, but the resulting color images have poor light and heat fastness.

Furthermore, the phenolic cyan coupler having a p-cyanophenylureido group at the 2-position and a cyclic alkylcarbonamide group at the 5-position described in U.S. Pat. No. 4,754,871 has excellent fastness of the resulting color image. However, it was inferior in terms of color development.

In recent years, color photographic materials such as color negative films, color reversal films, and color papers have not only improved the flatness and fastness of color images, but also increased sensitivity, higher image quality, faster processing, and the release of benzyl from color developing solutions. High color-forming properties (high coupling activity and high dye-forming efficiency) of couplers are strongly desired for purposes such as removal of alcohol and reduction of high-boiling point organic solvents.

Accordingly, an object of the present invention is to provide a cyan dye-forming coupler which has poor color development properties and which has poor color image fastness to light and heat.

Known black and white developing agents such as 3-pyrazolidones such as pyrazolidone or aminophenols such as N-methyl-p-aminephenol? They can be used alone or in combination.

These color developing solutions and black and white developing solutions generally have a pE of 9 to 12. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material being processed, but it is generally less than 3 ml per square meter of the light-sensitive material, and the bromide ion concentration in the replenisher is ? It can also be reduced to 500- or less by reducing it. When reducing the replenishment amount by 2, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank. Furthermore, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developer.

The time for color development processing is usually set between 2 and 5 minutes, but the processing time can be further shortened by using high temperature, high pH, and high concentration of color developing agent.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process (bleach-fixing process) or separately. Furthermore, in order to speed up the processing, a processing method may be used in which bleaching is followed by bleach-fixing. Furthermore, treatment with two consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment can be carried out as desired depending on the purpose. As a bleaching agent, for example, iron (III), copal)

The silver halide color photographic light-sensitive material of the present invention is generally subjected to water washing and/or stabilization steps after desilvering treatment.

The amount of water used in the washing process depends on the characteristics of the photosensitive material (for example, depending on the material used for the coupler etc.), the application, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent or forward flow, and various other factors. It can be set over a wide range depending on the conditions. this house,

8-253 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of water used for washing can be significantly reduced, but this increases the residence time of water in the tank, causing bacteria to propagate and the resulting suspended matter to attach to the photosensitive material. Problems such as slipping may occur. In the processing of color photosensitive materials of the present invention, as a solution to these problems,

Agents can also be used.

The pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 4.
It is 9, preferably 5-8. The washing water temperature and washing time can also be set variously depending on the characteristics of the photosensitive material, its use, etc., but generally it is 20 seconds to 10 minutes at 15 to 45°C, preferably 2
A range of 50 seconds to 5 minutes at 5 to 40°C is selected. Furthermore,

Table 7 shows the photographic performance of the cyan image obtained before the running process.

The numerical values shown in Table 7 were based on the method described in Example Column 1. Comparative couplers (a) and (b) are the same as the couplers described in Example Row 1.

From Table 7, it was observed that, compared to comparative couplers Samples 41 to 43, the couplers of the present invention all exhibited excellent performance with high sensitivity, high Dmax, and no increase in Dmin despite high activity. .

The photographic performance after the running was also evaluated in the same way, and the sensitivity and D
It became clear that there were no noticeable processing fluctuations with min and Dznax, and iJ Noh had stable processing. However, with the comparative coupler, although there was no change in Dmin, the sensitivity increased by 103 to 006, and the Dmax increased by 106.
~[L12 fluctuations were observed.

Subsequently, samples 41 to 45 of the present invention and 1 wipes 01 to 03, 10 and 06 prepared in Example 1 were subjected to imagewise exposure,
The samples of Example 1 and the samples of this example were processed with the same area amount by alternating these processes until the amount was twice the capacity of the color developing tank, and then the photographic performance was evaluated in the same way. As a result, the photographic performances of Samples 41 to 45 were the same as those shown in Table 7, and the photographic performances of Samples 01 to 03, 10 and 06 were also similar to those shown in Table 7. From these results, it was found that the coupler of the present invention can be used for both negative-type photosensitive materials and internal latent image type direct-positive photosensitive materials, and can be used in combination with the processing recipe shown in this example. .

Table 9 The numerical values in the table are values evaluated according to the method described in Example 1.

Comparative couplers (a) and (1)) are the same as couplers (IL) and (b) described in Example 1.

From Table 9, it can be seen that the sensitivity is high and D
max was also observed to be high.

Example 9 A coating film made of polyethylene terephthalate resin kneaded with titanium oxide (lower blade) was applied onto the film base, and as a reflective support, a sample was applied to this film base with exactly the same coating recipe and layer structure as described in Example 1. 71 to 81 were produced. These samples were given the same exposures as described in run column 1 and were run with the same treatments.

The color image obtained was superior in gloss and smoothness compared to the sample obtained in the actual m-row 1, and a clear color image was obtained. Furthermore, when the samples of this practical series were subjected to image exposure through the negative image f of the negative photosensitive material and the same processing was carried out, the printed images obtained had vivid colors and excellent sharpness. Combined with the gloss and smoothness, the image was clear.

The photographic performance of the cyan color image of the color image obtained in this way is exactly the same as the result shown in Example 1, and the high Dmax
, showed high sensitivity. In addition, the fastness of the color image was also confirmed in Example 4.
Similar to the results shown in , the couplers of the present invention were superior in fastness to light, heat, and moist heat compared to the comparative couplers.

Next, the raw storage stability of the samples of this example and each sample prepared in Example 1 was evaluated under the conditions shown in Table 10, based on changes in the sensitivity of cyan images. The results are also shown in Table 10.

Table 10 The numbers represent the difference between the sensitivity obtained after the raw storage conditions listed in the table and the sensitivity obtained from samples stored at 5° C. for the same period. The larger the value, the greater the change in sensitivity, indicating poorer survival.

From Table 10, it is clear that the couplers of the present invention exhibit stable performance with less fluctuation in sensitivity even in the shelf life of the sensitive material itself, compared to the comparative couplers.

Example 10 (Preparation of Sample 101) Sample 101, which is a multilayer color light-sensitive material having each layer having the composition shown below, was prepared on a cellulose triacetate film support that had been undercoated and bt coated.
