Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, a silver halide color photograph with good color reproducibility, little fogging, and high sharpness. Regarding photosensitive materials.

[Background of the Invention] As is well known, in conventional silver halide color photography, a silver halide photographic light-sensitive material containing a dye-forming coupler is developed using a phenylene diamine color developing agent or the like. As a result, the oxidized developing agent and the dye-forming coupler are coupled to form a dye and a color image is obtained.

Among the processes for obtaining color images, in the current process using the subtractive color method, a negative image is obtained by photographing and recording on a photographic photosensitive material called a color negative, and then developing it using the above-mentioned color development method. , and then print it on color paper using a printer.

In color negative photosensitive materials, for example, usually 400 to
500n1.500~600rv, 600~700rv
Three types of silver halide emulsion layers spectrally sensitized to each wavelength range contain yellow coupler, magenta coupler,
A multilayer structure containing a cyan coupler is adopted.

That is, a yellow dye is formed in the blue-exposed area, a magenta dye is formed in the green-exposed area, and a cyan dye is formed in the red-exposed area, thereby forming a so-called negative image.

After obtaining such a negative image, the color image is printed on a color paper consisting of a blue photosensitive layer also containing a yellow coupler, a green photosensitive layer containing a magenta coupler, and a red photosensitive layer containing a cyan coupler. It is common to obtain

However, the dyes used in color photography differ from the black-type dyes that are ideal in the subtractive color method, which absorb light only in a specific wavelength range, and have considerable asymmetric absorption in the central region of the spectrum. Since some of the light that you do not want to be absorbed is absorbed, sufficient color reproduction cannot be achieved as it is.For this reason, for example, in color negative films, masking using colored couplers is used to correct this irregular absorption. etc. are carried out,
This aims to achieve good color reproducibility.

Furthermore, negative spectral sensitivity correction is performed based on the subtractive color principle of the three primary colors and the characteristics of the human eye, and interimage effects are used to emphasize pure colors.

In this way, various color correction means are used in color negative photosensitive materials, but when the original signals recorded after various corrections as described above are printed on color vapor, conventional color paper itself has a color difference. Since there is no correction function at all, the problem remains that the color reproducibility of the entire system ends up deteriorating here.

In addition, the direct positive photosensitive materials used in color copiers and similar fields are photosensitive materials for direct observation by the user, so the color photosensitive materials used in color negative photosensitive materials, etc. Since masking techniques such as couplers cannot be used, it cannot be said that it has sufficient color reproducibility, and improvements are desired.

In addition, in this industry, high-quality silver halide color photographic materials are desired, and in particular, images are taken using silver halide photographic materials for color negatives and printed on silver halide photographic materials for color photographic paper. In the so-called color negative/positive system, in which the final image is obtained using a color negative, the problem is that the image quality, especially the image sharpness, of silver halide photographic materials for color photographic paper is lower than that of silver halide photographic materials for color negatives. ing.

In other words, photographic elements are processed each time they are run in an automatic processing machine installed in each laboratory, but as part of our efforts to improve our services to our users, we develop them on the same day that they are received for development. In recent years, it has become necessary to return items within a few hours or even tens of minutes from the time they are received, and there is a strong demand for short processing times in terms of shortening delivery times.

Conventionally, benzyl alcohol has been used in color developing solutions to achieve rapid processing. If the color developing solution does not substantially contain benzyl alcohol, the maximum density of the characteristic curve will decrease, the development time will need to be extended, and the speed will be impaired.

Therefore, in order to improve economy and environmental pollution, the color developer I solution does not substantially contain benzyl alcohol, and even with low replenishment, rapid processing is possible, the photographic performance is maintained constant, and the brown color At present, there is a strong desire for a method for processing photographic elements with excellent reproducibility.

The silver halide photographic light-sensitive material of the present invention can satisfy the above-mentioned requirements even if it is subjected to a development process using a color developing solution that does not substantially contain benzyl alcohol.

The term "substantially free of benzyl alcohol" as mentioned above means that the amount of benzyl alcohol is 2 mj or less per 1j of the color developing solution.If the content is 2 mj or less, there is almost no problem in terms of environmental pollution.

The color-forming ring @ drug used in the color-forming ring @ solution in the present invention includes known ones that are widely used in various color photographic processes.

These developers include amine phenol and p-phenylene diamine derivatives. These compounds are generally used in the form of salts, such as hydrochlorides or sulfates, since they are more stable than in the free state. Additionally, these compounds are generally present in a concentration of about 0.1 g to about 30 g per color developer solution IJ, preferably color developer solution IJ! About 1g to about 15
Use at a concentration of g.

Examples of aminophenol-based developers include 0-aminophenol, p-aminophenol, and 5-amino-2-
Oxytoluene, 2-amino-3-oxytoluene, 2
-oxy-3-amino-1°4-dimethylbenzene and the like.

Particularly useful primary aromatic amine color developers include N, N
It is a '-dialkyl-p-phenylenediamine compound, and the alkyl group and phenyl group may be substituted with any substituent.Among them, a particularly useful compound example is N,N'-diethyl-p- phenylenediamine hydrochloride, N-methyl-p-phenylenediamine hydrochloride, N,
N'-dimethyl-p-phenylenediamine hydrochloride, 2-

N'-diethylaniline, 4-amino-N-(2-methoxyethyl)-N-ethyl-3-methylaniline-p-
Examples include toluene sulfonate.

In addition to the above-mentioned primary aromatic amine color developer, known developer component compounds can be added to the color forming ring solution used for processing the silver halide photographic light-sensitive material of the present invention.

For example, alkaline agents such as sodium hydroxide, sodium carbonate, and potassium carbonate, alkali metal thiocyanates, alkali metal halides, water softeners, and thickening agents may be optionally contained.

In the color developer, an acid salt and a droxylamine compound are used as preservatives.

As the droxylamine compound, a sulfate of a compound represented by -a formula (V) is preferable.

(In the formula, RS+ and Rs2 represent hydrogen or an alkyl group having 1 to 5 carbon atoms which may have a substituent, provided that R8I and R
s2 never takes hydrogen at the same time. ) Substituents include sulfonic acid groups, hydroxy groups, alkoxy groups (methoxy, ethoxy, propyloxy, etc.), carboxyl groups, amino groups, etc., and these are described, for example, in U.S. Pat. No. 3,287,125. , 3,293,034
