Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material. More specifically, it relates to a silver halide color photographic material with improved color reproducibility, good sharpness, and high color development.

(Prior art) In silver halide color photographic materials, in order to form color images, yellow, magenta and cyan dyes are produced through a coupling reaction with an oxidized product of an aromatic primary amine developing agent. So-called dye-forming couplers (hereinafter simply referred to as couplers) are used. Among these, benzoylacetanilide type couplers and pivaloylacetanilide type couplers are often used as yellow couplers, and benzoylacetanilide type couplers have characteristics such as high coloring properties and a large molar extinction coefficient of the azomethine dye produced. Pivaloyl acetanilide couplers are known to have characteristics such as good tailing on the long wavelength side of the dye absorption spectrum (low secondary absorption) and high color image fastness.

In color negative photosensitive materials, efforts have been made to make the photosensitive material thinner in order to improve image sharpness, which is one of its most important properties. One way to make the sensitive material thinner is to reduce the volume of the coupler and the high-boiling organic solvent for coupler dispersion, but in order to realize this method, the molar absorption coefficient is large,
A coupler with a small molecular weight and high color development is required even when a small amount of a high-boiling organic solvent for dispersion is used.

From this point of view, it is considered that benzoylacetanilide type couplers having the above-mentioned characteristics are desirable as yellow couplers used in color negative sensitive materials.

However, benzoylacetanilide-type yellow couplers have the disadvantage that the long wavelength end of the absorption spectrum of the dye produced by camping with the oxidized product of an aromatic primary amine developing agent is poorly cut, which causes problems in terms of color reproduction. Ta.

As one method for solving this problem, a method has been proposed in which a compound that forms a magenta image as an inverse function of the exposure amount of the emulsion layer is used in the blue-sensitive silver halide emulsion layer (Japanese Patent Application Laid-Open No. 1983-1996-1). However, the compound described in the same publication is a magenta azo dye or a magenta ab dye whose auxochrome hydroxyl group is protected with an acyl group to temporarily shorten the wavelength of the absorption pilot flame. is also a compound that has absorption in the visible region.

(Problem to be solved by the invention I!I) However, as shown in the examples of the specification described in the same publication, such colored compounds are used in the blue-sensitive layer, which is the photosensitive layer furthest from the support. It absorbs a portion of the radiation that would otherwise be absorbed by the silver halide, reducing the sensitivity of the white layer or of the light-sensitive layer closer to the support, resulting in a balanced sensitivity. It has been found that this method cannot be used as a means to solve the above-mentioned problems because it is difficult to construct a photosensitive material.

Therefore, an object of the present invention is to solve the above-mentioned problems in silver halide color photographic materials. That is, an object of the present invention is to provide a silver halide color photographic material with improved sharpness and color reproducibility.

(Means for Solving the Problems) The above-mentioned object of the present invention is to provide a silver halide color photographic light-sensitive material comprising at least one blue-sensitive emulsion layer provided on a support, in which the blue-sensitive emulsion layer is as follows: Contains a yellow coloring coupler represented by the formula (!), and - the formula (■

- The compound represented by formula (II) is preferably used in a layer containing a blue-sensitive emulsion (not necessarily a layer containing a coupler represented by general formula CI>) or a layer adjacent to a blue-sensitive emulsion layer. This is an example. In the exposed areas of the blue-sensitive emulsion, color development is performed to generate an oxidized form of the aromatic primary amine developing agent in the exposed image, and the generated oxidized form of the developing agent couples with the yellow coupler. At the same time as producing yellow pigment - formula (U)

) In the exposed area where the bond with n-DP is broken, the dye generated from DP also diffuses into the processing solution and does not remain in the film, while in the unexposed area, the compound represented by general formula (n) is present in the film. The group represented by DP reacts with the developing agent to form a dye.The present invention corrects color turbidity of the color image thus generated due to sub-absorption on the long wavelength side of the dye generated from the benzoylacetanilide coupler. It is used as a masking dye for

The benzoylacetanilide type yellow coupler represented by the general formula (I) has a high color density and can reduce the amount of coupler used in the emulsion, which is advantageous for making the emulsion layer thin. Therefore, according to the present invention, it is possible to simultaneously improve sharpness by thinning the emulsion layer and to perform color correction without loss of sensitivity by using a substantially colorless masking material, that is, to improve color reproducibility. .

When reducing the amount of replenishment, it is preferable to prevent evaporation of the solution and air oxidation by reducing the contact area with the air in the processing tank, and by using means to suppress the accumulation of bromide ions in the developer. It is also possible to reduce the amount of replenishment.

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

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

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 materials used such as couplers), 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 conditions. Can be set over a wide range. Among these, the relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is

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 due to the increase in the residence time of water in the tank, bacteria will breed, and the generated suspended matter will adhere to the photosensitive material. In the processing of the color photosensitive material of the present invention, such problems can be solved by:
The method for reducing calcium ions and magnesium ions described in JP-A No. 62-288.838 can be used very effectively. Also, JP-A-57-8.542

Claims (1)

[Scope of Claims] A silver halide color photographic light-sensitive material comprising at least one blue-sensitive emulsion layer provided on a support, wherein the blue-sensitive emulsion layer contains a yellow coloring coupler represented by the following general formula (I). A silver halide color photographic material comprising a compound represented by formula (II) in a blue-sensitive emulsion layer or a layer adjacent thereto. General formula (I) ▲There are mathematical formulas, chemical formulas, tables, etc.▼ (In the formula, R_1 represents an aryl group, R_2 represents a hydrogen atom, a halogen atom, an alkoxy group, or an aryloxy group, and R_3 can be substituted with an aromatic ring. represents a group,
LVG represents a group that can be separated by a coupling reaction with an oxidized product of an aromatic primary amine developing agent, and l is 0 to 4.
represents an integer. However, when l is 2 or more, R_3 may be the same or different. Also, R_1, R_2, R_3 or LVG
