Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, it has high color density, excellent color image fastness, and This invention relates to a silver halide color photographic material with excellent stability.

(Prior Art) In the color photographic materials currently in use, so-called color couplers (having an active methylene group as a reactive position) are used which compile with the oxidized product of an aromatic primary amine developing agent to form an azomethine dye. A common method is to incorporate a silver halide emulsion and a silver halide emulsion into a light-sensitive material, and obtain a dye image through imagewise exposure and subsequent color development. As a color coupler, as is well known, the use of a two-equivalent coupler has the advantage that the amount of silver can be reduced more than a four-equivalent coupler. However, especially with regard to this type of coupler, the development of a coupler with excellent color development and fastness of the produced dye was a very important technical issue.

On the other hand, as a color image forming method using a silver halide photographic light-sensitive material, a method is often adopted in which colors are reproduced by a subtractive color method using yellow, magenta, and cyan dyes as the three primary colors. Among these, as magenta dye-forming couplers, those having a 5-pyrazolone core have been preferably used from the viewpoint of the hue and color density of the coloring dye. However, among these magenta couplers having a 5-pyrazolone core, there are only a few examples in practical use because a two-equivalent coupler that satisfies the various performances required for incorporation into light-sensitive materials has not been obtained. This is the actual situation.

For example, U.S. Pat. No. 4,351,897 describes compounds having an arylthio group as a leaving group as useful two-equivalent 5-pyrazolone magenta couplers. This compound has less staining during processing, which is often a problem with two-equivalent compounds, has high fastness of the magenta dye produced, and also has high stability of the coupler itself, so it does not cause white backgrounds in images during long-term storage. It was an excellent coupler with little occurrence of yellow stain in the parts.

However, the efficiency of azomethine dye formation is not sufficient from the viewpoint of color development, and in order to obtain high color density, it is necessary to incorporate a non-light-sensitive fine grain emulsion into the light-sensitive emulsion layer or an adjacent layer. , improvements were desired.

International Patent Application No.
No. 104,795 discloses those having an acylamino-substituted arylthio leaving group. This compound has improved coloring properties, which had been a problem up until then, and can provide sufficient coloring density without using the above-mentioned fine grain emulsion in combination.

However, when photosensitive materials were prepared and tested in accordance with the technology described in the above-mentioned patent, it became clear that a serious defect would occur if this coupler with excellent color forming properties was incorporated into the photosensitive materials. In other words, it has been found that when prints are made using color photographic paper using this coupler, density unevenness occurs in the magenta colored area, making it difficult to put it to practical use. This density unevenness occurs when a developing machine that transports a roll of color photographic paper has stripes of high magenta density along the direction of travel of the photographic paper; In a developing machine that transports the bleach-fix solution using a roller, the pattern of the reversing roller (a so-called sock roller with a pile-shaped cover) that flows from the developer to the bleach-fix solution causes areas with high magenta density. It has become clear that the problem becomes even worse when the coupler is combined with a silver halide emulsion having a silver chloride content of 90 mol % or more and rapid processing is carried out. When such density unevenness occurs, it is difficult to obtain good color prints, which is a fatal problem in putting the coupler into practical use.

(Problems to be Solved by the Invention) As is clear from what has been described above, an object of the present invention is to create a magenta coupler that can be made low in silver and has excellent fastness of the coupler itself and the produced magenta dye. An object of the present invention is to provide a silver halide photographic material which does not cause magenta density unevenness during processing.

The compound represented by IV) can be contained in either a photosensitive or non-photosensitive hydrophilic colloid layer constituting the silver halide photographic light-sensitive material.

The amount of the compound represented by the general formula (U), (II[) or (■) added is lXl0-' per mol of halogenated compound.
~5X10-'' moles are preferred, more preferably lX10-'~
1X10-'' moles are preferred.

If the amount added is less than the above, the effect of the present invention will not be sufficient,
Density unevenness occurs in the magenta colored area. - On the other hand, if the amount is more than the above, it is not preferable because it causes a decrease in sensitivity or inhibits development and causes a decrease in density.

-a The cause of density unevenness in magenta color development when using a 5-pyrazolone coupler (hereinafter referred to as the coupler of the present invention) having a leaving group represented by formula (1) at the coupling position is not clear. However, this seems to be related to the high color development of this coupler.

The compounds represented by the general formulas (II), (lI[) and (■) are well known as so-called antifogging agents or stabilizers. In other words, it can be added to silver halide emulsions to prevent fogging, or to reduce photographic property fluctuations (sensitivity,
It is known as a compound that has the effect of reducing gradation or fogging.

However, it is not known that the present invention is effective against density unevenness in the magenta coloring area that occurs when photosensitive materials incorporating the coupler of the present invention are processed. This was a new discovery that was completely unexpected based on existing knowledge.

In addition, among the compounds known as so-called antifogging agents and stabilizers, the formulas (n), (Ill) and (rV
In addition to the compounds represented by ), there is a group of compounds known as nitrogen-containing heterocyclic compounds that do not have a mercapto group (for example, hydroxytetraazaindene, adenine, or guanine). However, although these compounds have similar effects on preventing fogging and stabilizing photographic performance, they have little effect on density unevenness that occurs when using the coupler of the present invention.
When the amount added was increased, desensitization and development inhibition were significant, and we could not find anything that could confirm these effects. therefore,
The density unevenness improvement effect of the present invention is as follows: - pattern hole (n), (Ill
This is considered to be a novel effect unique to the compounds represented by ) and (TV). The effects of the present invention are particularly remarkable when using compounds represented by -monna (■).

Generally, the coating amount of the color coupler in a silver halide color photographic light-sensitive material is selected so as to obtain the required maximum color image density. The amount of silver halide emulsion required to develop the color is determined by taking into account the number of equivalents of the coupler and the color development efficiency.

When the coupler of the present invention is used to construct a photosensitive emulsion layer, the amount used is 0.1 to 1.0 mol per mol of silver halide, as in other general usage methods. Can be used between. However, the present inventors conducted research to improve the density unevenness and found that by limiting the ratio of the silver halide emulsion and the coupler of the present invention to a specific range, It has been revealed that the density unevenness improving effect of the compound represented by When the condition of 2.0≦R≦5.5 R-halogenated 1 liter (mol)/coupler (mol) is satisfied, the degree of improvement in density unevenness is significantly improved.

At this time, if the value of R is less than 2.0, the utilization efficiency of the coupler will be low, which is not preferable. On the other hand, if it exceeds 5.5, the contribution to improving density unevenness will be small.

Also, the value of R above is 3.0≦R≦5. 0 Uses that satisfy the following conditions give particularly favorable results.

Furthermore, as a result of studies conducted by the present inventors, density unevenness when using the coupler of the present invention is also influenced by the swelling rate of the hydrophilic colloid layer on the support when the light-sensitive material is immersed in a color developer. (The swelling ratio in the present invention is the ratio of the thickness of the hydrophilic colloid layer in the color development processing solution to the thickness of the hydrophilic colloid layer on the support in a dry state, expressed as a percentage. ). That is, when the swelling ratio is 200 to 300%, the effects of the present invention described above are further improved.

When the swelling ratio is less than 200%, density unevenness is less likely to occur, but the development speed is slow and the density is lowered.

On the other hand, if the swelling ratio exceeds 300%, the contribution to improving density unevenness will be small.

The color photographic light-sensitive material of the present invention can be constructed by coating at least one blue-sensitive silver halide emulsion layer, one green-sensitive silver halide emulsion layer, and one red-sensitive silver halide emulsion layer on a support. In general color photographic paper, the layers are usually coated on the support in the above order, but they may be applied in a different order. These photosensitive emulsion layers contain a silver halide emulsion sensitive to each wavelength range, and dyes that are complementary colors to the light to which they are exposed - yellow for blue, magenta for green, and cyan for red. By containing a so-called color coupler, subtractive color reproduction can be performed. However, the coloring hues of the photosensitive layer and the coupler may not correspond as described above.

As the silver halide emulsion used in the present invention, one consisting of silver chlorobromide or silver chloride that does not substantially contain silver iodide can be preferably used. Here, "substantially free of silver iodide" means that the silver iodide content is 1 mol% or less, preferably 0.2 mol% or less. The halogen composition of the emulsion may be different or the same among the grains, but if an emulsion in which the halogen composition is the same among the grains is used, it is easy to make the properties of each grain uniform. In addition, regarding the halogen composition distribution inside silver halide emulsion grains, there are grains with a so-called uniform structure in which the composition is the same in every part of the silver halide grain, and grains with a core inside the silver halide grain and a shell surrounding it. (Shell) [-layer or multiple layers] Particles with a so-called layered structure in which the halogen composition is different, or
Particles with a structure that has parts with different halogen compositions in a non-layered manner inside or on the particle surface (if on the particle surface, parts with different compositions are joined on the edge, corner, or surface of the particle) are appropriately selected and used. be able to. In order to obtain high sensitivity, it is more advantageous to use one of the latter than grains with a uniform structure, and it is also preferable from the viewpoint of pressure resistance, when the silver halide grains have the above-mentioned structure. Boundaries between parts with different halogen compositions may be clear boundaries, or may be unclear boundaries due to the formation of mixed crystals due to compositional differences, or may be caused by active continuous structural changes. It may be something that has.

Regarding the halogen composition of these silver chlorobromide emulsions, any silver bromide/silver chloride ratio can be used. This ratio can vary over a wide range depending on the purpose, but those with a silver chloride ratio of 2% or more are preferably used.

Furthermore, so-called high-silver chloride emulsions having a high silver chloride content are preferably used in light-sensitive materials suitable for rapid processing. The silver chloride content of these high silver chloride emulsions is preferably 90 mol% or more,
More preferably 95 mol% or more.

Such a high silver chloride emulsion preferably has a structure in which the localized silver bromide layer is provided inside and/or on the surface of the silver halide grains in a layered or non-layered manner as described above. The halogen composition of the localized layer preferably has a silver bromide content of at least 10 mol%, more preferably more than 20 mol%. These localized layers can then be inside the particles, on the edges, corners or faces of the particle surfaces. One preferred example is one in which part of the corner of the particle is epitaxially grown.

On the other hand, in order to suppress the decrease in sensitivity when photosensitive materials are subjected to pressure, even in high silver chloride emulsions with a silver chloride content of 90 mol% or more, grains with a uniform structure with a small distribution of halogen composition within the grains are used. It is also preferable to use

Furthermore, it is also effective to further increase the silver chloride content of the silver halide emulsion for the purpose of reducing the amount of replenishment of the development processing solution.

In the case of this birch, its silver chloride content is 98 mol% to 10
Emulsions of almost pure silver chloride, such as 0 mol %, are also preferably used.

The particle size distribution thereof is preferably so-called monodisperse, with a coefficient of variation (standard deviation of particle size divided by average particle size) of 20% or less, preferably 15% or less. At this time, in order to obtain a wide latitude, it is preferable to blend the above-mentioned monodispersed emulsions in the same layer or to apply multilayer coating.

In the present invention, among these particles, it is preferable to contain particles having the above-mentioned regular crystal shape in an amount of 50% or more, preferably 70% or more, and more preferably 90% or more.

In addition to these, the average aspect ratio (yen equivalent diameter/

The purpose of these compounds can be achieved by co-emulsifying them with a coupler and adding them to the photosensitive layer, usually in an amount of 5 to 100% by weight based on the corresponding color coupler. In order to prevent the cyan dye image from deteriorating due to heat and especially light, it is more effective to introduce an ultraviolet absorber into the layers on both sides adjacent to the cyan coloring layer.

Among the above antifading agents, spiroindanes, hindered amines, and the like are particularly preferred.

In the present invention, it is preferable to use the following compounds together with the above-mentioned couplers.

That is, a compound (F) that chemically bonds with the aromatic amine developing agent remaining after color development processing to produce a chemically inert and substantially colorless compound and/or an aroma remaining after color development processing. For example, in storage after processing, the compound (G) that chemically bonds with the oxidized form of a group amine color developing agent to produce a chemically inert and substantially colorless compound may be used simultaneously or singly. This is preferable in order to prevent staining and other side effects caused by the formation of coloring dyes due to the reaction between the color developing agent or its oxidized product remaining in the film and the coupler.

A preferred compound (F) has a second-order reaction rate constant with p-anisidine of 2 (in trioctyl phosphate at 80°C) of 1,0 e /mol-sec to I
It is a compound that reacts in the range of X I CV'l /mol·sec. In addition, the second-order reaction rate constant is based on JP-A-63-
It can be measured by the method described in No. 158545.

When R2 is larger than this range, the compound itself becomes unstable and may react with gelatin or water and decompose. On the other hand, if R2 is smaller than this range, the reaction with the remaining aromatic amine developing agent will be slow, and as a result, it may not be possible to prevent the side effects of the remaining aromatic amine developing agent, which is the objective of the present invention.

The occupied area ratio (%) of white pigment fine particles per defined unit area is calculated by dividing the observed area into adjoining unit areas of 6 μm x 5 μm, and dividing the area of fine particles projected onto that unit area. It can be determined by measuring the occupied area ratio (%) (Ri). The coefficient of variation of the occupied area ratio (%) can be determined by the ratio S/R of the standard deviation S of R1 to the average value (R) of R8. The number (n) of target unit areas is preferably 6 or more. Therefore, the coefficient of variation s/R can be determined.

In the present invention, the coefficient of variation of the occupied area ratio (%) of the pigment fine particles is preferably 0.15 or less, particularly 0.12 or less. If it is 0.08 or less, the dispersibility of the particles can be said to be "substantially uniform."

The number of stages in the normal multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 4.

According to the multistage countercurrent method, the amount of washing water can be greatly reduced, for example, from 0.51 to 1 j per rrr of photosensitive material! The following is possible, and the effects of the present invention are remarkable; however, due to the increased residence time of water in the tank, problems such as bacteria propagation and the resulting floating matter adhering to the photosensitive material may occur. In the processing of the color light-sensitive material of the present invention, as a solution to such problems, the method for reducing calcium and magnesium described in Japanese Patent Application No. 131632/1988 can be used very effectively.

It is 40 times to 40 times. or 11 or less per 1 d of photosensitive material,
Preferably it is 500- or less. Further, replenishment may be performed continuously or intermittently.

The liquid used in the water washing and/or stabilization step can also be used in the previous step. An example of this is to flow the overflow of washing water, which has been reduced by a multi-stage countercurrent system, into a bleach-fixing bath, which is a pre-bath, and replenishing the bleach-fixing bath with concentrated liquid to reduce the amount of waste liquid.

The total process time of the desilvering process, water washing and stabilization process of the present invention is 2 minutes or less, preferably 30 seconds to 1 minute 30 seconds.

The total time here refers to the time from when the silver halide color photographic light-sensitive material comes into contact with the first bath in the desilvering process until it comes out of the last bath in the water washing or stabilization process. Air time for is included.

Here, "the sum of the processing times of desilvering treatment, water washing treatment, and stabilization treatment is 2 minutes or less" refers to the treatments performed before the desilvering treatment and drying process (more specifically, the water washing and/or stabilization treatment). For example, the sum of the processing times such as (1) Desilvering→Water washing, (2) Desilvering-stabilization, and (2) Desilvering-Water-washing-Stabilization is two minutes or less.

Example 1 A multilayer color photographic paper having the layer structure shown below was prepared on a paper support laminated on both sides with polyethylene. The coating solution was prepared as follows.

A first layer coating solution was prepared by mixing and dissolving in 420 g of a silver chlorobromide emulsion containing a sensitizing dye (1.90.0 mol % bromide, average grain size 1.02 μ, coefficient of variation 9.7%). . Coating solutions for the second to seventh layers were also prepared in the same manner as the coating solution for the first layer.

Samples B to J were prepared by changing the composition of the fifth layer (green-sensitive layer) from sample A as shown in Table 1.

These 10 types of samples were subjected to gradation exposure for sensitometry through a green filter and an optical wedge using a photosensitive needle (Model FWH manufactured by Fuji Photo Film Co., Ltd., color temperature of the light source: 4300 K). The exposure at this time was 0.
The exposure time was 1 second and the exposure amount was 250 CMS.

Thereafter, color development processing was performed using the steps and processing solution shown below. A paper processor FPSR-2030 manufactured by Fuji Photo Film Co., Ltd. was used as an automatic developing machine.

The photographic characteristics were evaluated in terms of three items: overlap density, relative sensitivity, and maximum density. Regarding the relative sensitivity, the reciprocal of the exposure amount required to give a density equal to the fog density plus 0.5 was used as the sensitivity, and the sensitivity was expressed as a relative value with the sensitivity of sample A as 100.

Regarding density unevenness in the magenta coloring area, the magenta density is 0. A sample subjected to uniform exposure adjusted to 12. 20 samples each were processed using Ocho X16.5C11 and evaluated as follows according to the degree of unevenness.

6.70 As is clear from the results in Table 2, when a two-equivalent magenta coupler other than the one of the present invention is used, the bromide is 1! Unless a fine grain emulsion is added, sufficient color density cannot be obtained. In this case, not only is extra silver halide required, but there is also the disadvantage that the sensitivity decreases due to the addition of the silver bromide fine grain emulsion.If the two-equivalent magenta coupler of the present invention is used, High color density can be obtained without adding fine grain emulsion, but density unevenness occurs in the magenta colored area, making it difficult to put it to practical use. It becomes possible to obtain an excellent photosensitive material with little density unevenness.

The color photographic paper thus obtained is used as a sample. Samples L to Z were prepared by changing the composition of the third layer as shown in Table 3 below. However, the swelling rate of the sample was determined by adjusting the amount of hardener added. The swelling ratio in the present invention is defined as the thickness of the photosensitive material in a dry state Lt, the thickness of the support, and the increase in thickness when the photosensitive material is immersed in the color development processing solution shown below. The above thicknesses are the values calculated using the following formula (% formula %) when
ether). Regarding the increase in film thickness in the processing solution, the film thickness of the photosensitive material in a dry state was subtracted from the film thickness of the photosensitive material that had been soaked in the processing solution at 35° C. for 45 seconds.

These 16 types of samples were tested for photographic properties and density unevenness in the same manner as in Example 1. However, the treatment steps and treatment liquid were changed to those shown below. Further, as an automatic developing machine, the same model as in Example 1 was used after being modified.

The results are shown in Table 4. The relative sensitivities in the table are expressed as relative values with the sensitivity of the sample as 100.

Although this is improved, the degree of density unevenness in the magenta colored area is further worsened in systems using high silver chloride emulsions. On the other hand, it can be seen that when the compound of the present invention is used in combination, density unevenness is significantly improved without impairing color development or sensitivity.

It is also seen that density unevenness can be further improved by decreasing the molar ratio of silver halide to magenta coupler contained in the green-sensitive emulsion layer.

Further, by reducing the swelling rate of the light-sensitive material in the color developing solution, density unevenness can also be improved. However, if the swelling rate is less than 200%, development will be delayed and sensitivity and maximum density will decrease.

Example 3 Using the processed samples prepared in Examples 1 and 2, the fastness of the magenta dye image and the stability of the white background were tested.

Seven types of samples were used: A, C, H, M, U, and ■.

The test method is to test each treated sample at a temperature of 80℃ and a relative humidity of 70%.
When stored for 10 days under the conditions of 1. and 6 days using a xenon fade meter with an illuminance of 84,000 lux, the initial magenta density was 1.
The rate of decrease in density from 0 and the increase in yellow density on a white background were measured. These results are shown in Table 5.

The combination of the fifth expression makes it possible for the first time to use a two-equivalent magenta coupler with excellent color development to provide an excellent light-sensitive material with no uneven density.

Moreover, this makes it possible to provide a light-sensitive material which has excellent stability of dye images and white backgrounds and has good (rapid) processing suitability.

Patent Applicant: Fuji Photo Film Co., Ltd. As is clear from the results in Table 5, the two-equivalent magenta coupler of the present invention has excellent color image fastness and white background stability. This performance was almost equal to that of the comparative two-equivalent coupler, indicating that the coupler of the present invention has both excellent color forming properties and excellent stability of the dye and the coupler itself.
