Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method for forming a dye image by color development processing a silver halide color photographic light-sensitive material, and more specifically relates to a method for forming a dye image by color-developing a silver halide color photographic light-sensitive material. The present invention relates to a method for forming a dye image by processing a silver color photographic material with a color developing solution containing a black and white developing agent in the presence of an aromatic primary amine color developing agent.

[Prior Art] Generally, silver halide color photographic light-sensitive materials have three types of photographic silver halide emulsion layers on a support that are selectively spectrally sensitized to have sensitivity to blue light, green light, and red light. has been painted. For example, in silver halide photographic materials for color negatives, generally a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer are coated in this order from the exposed side. A bleachable yellow filter layer is provided between the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer to absorb the blue light that passes through the blue-sensitive silver halide emulsion layer. It is provided. Further, each emulsion layer is provided with other intermediate layers for various special purposes, and a protective layer as the outermost layer. For example, in a silver halide photographic light-sensitive material for color photographic paper, generally, from the side to be exposed, a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a blue-sensitive silver halide emulsion layer are arranged in this order. As with the silver halide photographic light-sensitive materials for color negatives, interlayers such as an ultraviolet absorbing layer, protective layers, etc. are provided for special purposes. It is also known that each of these silver halide emulsion layers is provided in a different arrangement from the above, and furthermore, each silver halide emulsion layer is sensitive to substantially the same wavelength range for each color light. It is also known to use a photosensitive silver halide emulsion layer consisting of two layers. In these silver halide color photographic light-sensitive materials, exposed silver halide grains are developed using, for example, an aromatic primary amine color developing agent as a color developing agent, and the chemically formed color developing agent is oxidized. A dye image is formed by reaction of the product with a dye-forming coupler. In this method, cyan couplers, magenta couplers, and yellow couplers are typically used to form cyan, magenta, and yellow dye images, respectively.

In recent years, in the industry, silver halide color photographic materials (hereinafter referred to as color photosensitive materials) that can be processed quickly, have high image quality, have excellent processing stability, and are low cost have been developed. In particular, silver halide color photographic materials that can be rapidly processed are desired.

In other words, silver halide photographic photosensitive materials are processed on a running basis using automatic processing machines installed at each state museum, but as part of an effort to improve service to users, processing is carried out on the same day that processing is received. Development of silver halide color photographic light-sensitive materials that can be processed and processed more quickly is required, and in recent years, it has even been required to be returned within a few hours of receipt. is urgently needed.

Generally, such dye image formation involves subjecting the exposed color photosensitive material to color development, bleaching, and fixing (or bleach-fixing), and then washing with water, but rapid processability is particularly required. In color photographic paper, shortening the color development process is of considerable technical and practical importance.

It is known to use a development accelerator when developing with a primary aromatic amino color developer. Although a wide variety of compounds have been extensively used for this purpose in the past, compounds with a high degree of activity as phenomenon promoters often have the disadvantage of forming fog. However, among such compounds, certain black-and-white developing agents exhibiting superadditivity in color development can provide a development accelerating effect with relatively low fog formation compared to other development accelerators. Examples of such black and white developing agents include N-methyl-p-aminephenol described in U.S. Pat. No. 2,417.514;
1-phenyl-3-pyrazolidone as described in No. 1m, No. 185, and N as described in JP-A-50-15554.

N,N',N'-tetramethyl-p-phenylenediamine is mentioned. Further, the superadditive development/mechanism in this color development is described by G, F, Vanyee + En, rJ, P, S, No. 20, p. 94 (1972).

However, although the above-mentioned black and white developing agent has satisfactory performance in terms of the development accelerating effect, it has the following drawbacks. That is, for example, 1-phenyl-3-pyrazolidone<g, referred to as phenidone. ) is effective as a development accelerator for aromatic primary amine color developing agents when added to a color developer; This has the disadvantage of causing color turbidity and also has the disadvantage of deteriorating the storage stability of the color developer. The same drawback is seen with N-methyl-0-aminophenol. On the other hand, the above N, N.

When N',N'-tetramethyl-p-phenylenediamine is added to a color developer, it causes less color turbidity than phenidone, but it imparts stain to processed silver halide color light-sensitive materials when left alone, and It has the disadvantage of deteriorating the storage stability of color developers.

On the other hand, it is also known to incorporate such 1-aryl-3-pyrazolidones into a color photosensitive material in advance, and to perform color development after exposure. According to this method, a remarkable effect of promoting color development can be obtained, for example, U.S. Pat. No. 3,902,905, U.S. Pat. 5
No. 7-144547, No. 58-50532, No. 58-
No. 50533, No. 58-50534, No. 58-505
No. 35, No. 58-50538, No. 59-104641
No. 59-1m8649, No. 59-1l1328, etc.

However, when 1-aryl-3-pyrazolidones were conventionally incorporated into color light-sensitive materials, there were several problems. That is, (1) if an amount sufficient to impart a sufficient development accelerating effect is incorporated, color turbidity occurs. For example, when color development occurs in a silver halide emulsion layer containing a yellow coupler, due to the presence of 1-aryl-3-pyrazolidones, other couplers (
For example, color development in the layer containing magenta coupler is partially induced, reducing the color purity of the image.

(2) A decrease in the floor vitr<γ) occurs. This is a particularly significant problem when the couplers used have relatively slow color development rates.

(3) Desensitization or fogging occurs during storage of photosensitive materials. This depends on the built-in amount of 1-aryl-3-pyrazolidones, so it can be reduced by reducing the amount, but the effect of promoting development cannot be exerted.

(4) When a photosensitive material is immersed in a color developer, a considerable portion of the incorporated 1-aryl-3-pyrazolidones dissolves into the developer before contributing to color development.

This not only means that more than the required amount must be incorporated, but also means that 1-aryl-3-pyrazolidones accumulate in the developer when color photosensitive materials are continuously processed. In general, 1-aryl-3-pyrazolidones in color developing solutions have a large effect on photographic performance (especially sensitivity, l@1ll), so fluctuations in the concentration of 1-aryl-3-pyrazolidones during processing are extremely inconvenient. It is.

In order to solve these problems, various improved techniques have been proposed. For example, JP-A-57-21m47
No. 58-50532, No. 5J1-50533,
Although 1-aryl-3-pyrazolidones having a phenyl group at the 5-position are described in No. 58-50534, the development accelerating effect of these compounds is generally insufficient.

Also, JP-A-59-104641, JP-A No. 59-1l13
No. 28 describes 1-aryl-3-pyrazolidones in which the 2- or 3-position is blocked, but although these compounds can reduce the storage disadvantage by 1 ml, they do not meet the above (1). , (2) and (4) are not solved at all.

JP-A No. 59-1m6649 discloses a method for adding 1-aryl-3-pyrazolidones, but problems (1), (3), and (4) remain unsolved even with this technique. .

Furthermore, JP-A-56-64339, JP-A No. 56-8616
No. 5 has 1 in which the hydroxymethyl group at position 4 is acylated.
-Aryl-3-pyrazolidone compounds are disclosed. Although this compound provides relatively good photographic performance (development progress, gradation), it has not completely solved the problem (4) above.

As mentioned above, 1-aryl-3-
Despite the speed of the color development process, several practical problems remained when performing color development using superadditive development using black and white developing agents such as pyrazolidone. .

Specifically, the following compounds can be mentioned as representative examples.

General formula [I] contained in the color photosensitive material of the present invention,
The 1-aryl-3-pyrazolidone compound represented by [n] or [I[] may be in any layer of the photographic constituent layer on the support. The term "photographic constituent layers" as used herein refers to photosensitive silver halide emulsion layers and non-photosensitive layers such as interlayers, subbing layers, and protective layers.

In order to add the compound represented by the general formula [I], [II] or [I[I] of the present invention to a predetermined photographic constituent layer of a silver halide color photographic light-sensitive material, hydrophilic dispersed directly in a colloid solution, or dispersed directly in a colloid solution, for example methanol, ethanol, isopropanol, acetone,
It may be added to the hydrophilic colloid solution after being dissolved in one or a mixture of two or more suitable solvents such as methyl ethyl ketone, dimethylformamide, dioxane, and ethyl acetate.

Also, for example, one of high boiling point organic solvents such as dibutyl phthalate, dibutyl phthalate, tri-cresyl phosphate, trioctyl phosphate, etc.
After dissolving in a seed or a mixed solvent of two or more types, it may be emulsified and dispersed in a hydrophilic colloid solution. Furthermore, when the photographic constituent layer is a photosensitive silver halide emulsion layer, this compound can be emulsified and dispersed simultaneously with the coupler and then added to the coating solution.

When adding the compound represented by the general formula [II, [II or [1]] of the present invention to the coating solution, when adding this compound to the photosensitive silver halide emulsion layer, Any period may be used as long as it has been adjusted. When the photosensitive silver halide emulsion is a surface latent image type emulsion that mainly forms a latent image on the grain surface, it may be prepared at any time after chemical ripening and optical sensitization. Further, when the photosensitive silver halide emulsion is an internal latent image type emulsion that mainly forms latent images inside the grains, it may be carried out at any time after the silver halide emulsion has been prepared and optically sensitized. Further, when the photographic constituent layer is a non-photosensitive layer, it may be added at any time before the non-photosensitive layer is coated, but it is preferably added immediately before coating.

The compound represented by the general formula [E], [II] or [I[[] of the present invention can be added to a photosensitive silver halide emulsion layer and/or a photographic constituent layer of a non-photosensitive layer. When added to a light-sensitive silver halide emulsion layer, it may be added to any of the blue-sensitive, green-sensitive, and red-sensitive silver halide emulsion layers. In this case, it may be added to each of these layers, or even only to one layer.

When the compound represented by the general formula [II, [II] or [I[[] of the present invention is added to the non-photosensitive layer, an undercoat layer,
Although it may be added to either the intermediate layer or the protective layer, it is generally preferable to add it to the undercoat layer or the lowest layer in contact with the undercoat layer.

When adding a compound represented by the general formula [1m, [II] or [1m] to a color photosensitive material, the above conditions (
It is determined to satisfy 1) and (2).

The color developing solution of the present invention contains a compound represented by the general formula [II]. When the 1-aryl-3-pyrazolidone compound contained in the color photosensitive material is represented by the general formula [II, the 1-aryl-3-pyrazolidone compound contained in the color developing solution is
-Aryl-3-pyrazolidone and 1-aryl-3-pyrazolidone contained in the color photosensitive material must be the same.

Among the compounds represented by the general formula [II, [II or [II]], preferred are 1-aryl-3-pyrazolidone compounds having at least one substituent at the 4-position or precursors thereof. 'Furthermore, when the color light-sensitive material contains a compound represented by the general formula [II] or [1], a 1-aryl-3-pyrazolidone compound is produced as a result of hydrolysis of the compound under alkaline conditions. , must be the same as the 1-aryl-3-pyrazolidone contained in the color developer.

In the present invention, the 1-aryl-3-pyrazolidone compound (x mol/f) contained in the color photosensitive material and the 1-aryl-3-pyrazolidone compound (y mol/l) contained in the color developer are particularly have important meaning. That is,
When processing a color photosensitive material continuously while replenishing the color developer replenisher, the 1-aryl-3-pyrazolidone compound eluted from the color photosensitive material gradually accumulates in the color developer, causing the processing (It is necessary to carry out the process under specific conditions in which the 1-aryl-3-pyrazolidone shock in the color developer does not fluctuate greatly. Therefore, the color developer replenisher is replenished twice per 1 m2 of color photosensitive material. In this case, it is necessary to satisfy 0.7≦A≦1.3.

When A exceeds 1.3, the accumulation of 1-aryl-3-pyrazolidone during color development gradually increases with continuous processing, leading to fluctuations in photographic performance. Desensitization, lower than maximum density, and color turbidity occur.

On the other hand, if it is less than 0.7, the concentration of the 1-aryl-3-pyrazolidone compound in the color developing solution will decrease as processing is continued. As a result, 1-aryl-
It becomes impossible to sufficiently speed up the color development process using only the 3-pyrazolidone compound.

The value of one shift of A above is preferably 0.3 or more and less than 30.

mol is preferable, and 2 is 150 to 40 (hR/v”1
Particularly preferred are conditions where the amount is 0-4 mol.

The above 10-5 ≦ Compared to this, when only this amount is added to a color photosensitive material, the amount added is not enough to obtain a sufficient development accelerating effect.

On the other hand, the concentration of the 1-aryl-3-pyrazolidone compound in the color developing solution is also lower than the concentration conventionally used.

The present invention uses a smaller amount of both the color photosensitive material and the color developing solution than has been conventionally used, and can obtain much higher developability than the conventional case where each is added to only one of them. However, because the amount added is small, it has often caused problems in the past. By using a 1-aryl-3-pyrazolidone compound, it has become possible to significantly reduce the adverse effects such as color turbidity, decrease in maximum density, and deterioration of gradation.

The color developer replenisher of the present invention preferably does not substantially contain 1-aryl-3-pyrazolidone compounds from the viewpoint of long-term storage stability of the color developer, but it is not necessarily necessary that the color developer replenisher contains no 1-aryl-3-pyrazolidone compound. However, the concentration of the 1-aryl-3-pyrazolidone compound contained in the color developer may be 1 m 5 or less, preferably 1/10 or less.

The concentration (y) of the 1-aryl-3-pyrazolidone compound in the color developer of the present invention must satisfy 10-5≦y≦10-3, preferably 2X10-5≦y≦7×10- There is. The upper limit of y is mainly limited by color turbidity and deterioration of color development, and the lower limit is limited by the ability to promote development.

Specifically, they are silver chloride, silver bromide, silver chlorobromide, silver iodobromide, silver chloroiodide, and silver chloroiodobromide. Further, the grain size of these silver halide emulsions may be of any value, but preferably has an average grain size of about 0.1 to 3.0 μm.

The crystal structure of these silver halide grains may be uniform from the inside to the outside, or may have a layered structure in which the inside and outside are different. Further, the silver halide may be a surface latent image type that forms a latent image mainly on the surface, or an internal latent image type that forms a latent image mainly inside the grain.

The reflection density of each of the obtained samples was measured using monochromatic blue light, and the gradation and maximum density of the yellow dye image were determined. The results are shown in Table 1. The gradation in the table represents the slope of the reflection density of 05 to 1.5 in the characteristic curve.

From the results shown in Table 1, it can be seen that when (Knee 4) is added only to the color developing solution, the development progress increases as the amount added increases, but the effect of accelerating the phenomenon at 40 seconds is sufficiently preceded, so 5
10-4 mol/1 or more is required. - When added only to a photosensitive material, 5 x 10-5 mol/II2 or more is required to obtain a sufficient development accelerating effect, but if too much is added, the gradation and maximum density will be reduced. It will drop.

On the other hand, a remarkable development accelerating effect was observed in the samples added to the photosensitive material and the color developing solution. It can be seen that the gradation and maximum density are also high in the case of 4 to 5×10 −4 .

Below is a margin Example-2 Samples 1 to 5 prepared in Example-1 were exposed to blue color separation light, and the amounts added were the same as in Example-1 (I-4). Color development processing was performed for 60 seconds using five types of developing solutions. The density of the obtained yellow dye image was measured using monochromatic blue and green light to determine the green density at a blue reflection density of 15. The results are shown in Table-2.

From the results shown in Table 2, when (I-4) is added to both the photosensitive material and the color developer, which are the conditions of the present invention, Table 2 shows that
It can be seen that almost no color turbidity occurs when I-4 is added in a small amount, which provides the rapid development accelerating effect, high gradation, and maximum density seen in Sample No. 1.

Add 2.5g of pure water to make 1y, and use 10% potassium hydroxide with a trowel to make pH=1m. Adjust to 1.

As the bleach-fix replenisher, the bleaching window solution 1 shown in Example 1 with the color developing solution removed was used.

Sensitometry was performed using sample 3 every time 500 tl of replenisher was refilled to 1 m2fi of color developing solution to examine fluctuations in photographic performance during continuous processing (color developing time 60 seconds). The results obtained are shown in Table 4.

Under this condition, x, y, z, and A are the peaks in Table 3 (z=150).

From the results shown in Margin Table 4 below, it can be seen that in treatments where the A value falls within the range of 07 to 1.3, good photographic performance is exhibited even when the color developer replenisher is replenished at 2000 mR per e.

Example-4 Example-3 was repeated. However, color development was performed using the same method used in Example-1, with potassium bromide being 0.7 g, and the exemplified compound being 2 x 10-4.3 x 10-4.4 x 10

Table 5 shows the A values under these conditions.

Margin below The obtained sensitometric results are shown in Table 6.

From the results shown in Table 6, it can be seen that when the A value is between 0.7 and 1.3, there is almost no variation in gradation and photographic performance due to running processing.

Margin Example-5 Below: Layer 2 of color photosensitive materials 1 to 5 used in Example 1
Experiments similar to those in Examples 1 to 3 were repeated using equimolar amounts of (II-7) in place of (I-4) and (I-4) in the color developing solution. As a result, the A value was set to 0.7 to 1.3 at the same time as in Examples 1 to 3, and the 1-aryl-3-pyrazolidone in the color developing solution was set to 8X10-4 or less. gives a yellow dye image, and
It was found that running processing had almost no effect on photographic performance.
