Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material having excellent color reproducibility.

[Background of the Invention] In color photography using silver halide color photographic light-sensitive materials, color reproduction is generally performed by a subtractive color method. That is, in general silver halide color photographic materials, a yellow dye-forming coupler (hereinafter simply referred to as "yellow coupler") is contained in the blue light-sensitive emulsion layer, and a magenta dye is contained in the green light-sensitive emulsion layer. Forming coupler (
A cyan dye-forming coupler (hereinafter simply referred to as "magenta coupler") is used in the red light-sensitive emulsion layer (hereinafter simply referred to as "magenta coupler").
In the color development process after imagewise exposure, the oxidized product of the color development process produced by the development of the photosensitive silver halide and the dye-forming coupler undergo a coupling reaction, respectively. Yellow, magenta, and cyan pigments are formed, and color reproduction is thereby performed.

The quality of color reproducibility is one of the most important performances that determine the quality of color photographs. Therefore, since the invention of the principle of color photography, many studies have been made to improve color reproducibility.

There are many factors that affect color reproducibility, but a particularly important factor is the spectral absorption characteristics of the coloring dye.

In principle, the spectral absorption characteristics of a coloring pigment can be arbitrarily selected to a certain degree by changing the chemical structure of the coloring pigment, but in reality, it must be compatible with the above-mentioned coloring phenomenon treatment, and this is quite limited. It will be done. For this reason, although many studies have been made on many compounds to date, the reality is that no one has yet been found that is fully satisfactory.

Specifically, the spectral absorption characteristics of coloring dyes that are preferable for color reproduction are the wavelength that provides the maximum spectral absorption in the visible region (hereinafter referred to as "main absorption"), and the shape of the main absorption peak that is appropriate. , there is little extra absorption other than the main absorption (hereinafter referred to as "secondary absorption J"). First,
It is generally known that main absorption can be improved to a considerable extent by selecting the substituents of the coupler and the high-boiling point organic solvent for the coupler, and even at present it is possible to select an appropriate one. It can be said that it has been done. However, regarding sub-absorption, especially in the blue region of magenta and cyan dyes, sub-absorption in the blue region does not have a serious negative effect on color reproducibility, so in the industry, masking methods using colored couplers and interimage effects are generally used. Improvements are being made through methods, etc. However, these methods are not always available. For example, the masking method using colored couplers can be used for intermediate images such as color negative films, but cannot be used for final images such as color reversal films and color photographic papers. Therefore, it is desired to develop a coupler that provides a coloring dye with less side absorption.

Examples of magenta couplers with low side absorption include pyrazolinobenzimidazole series described in German Patent Nos. 1,070,030 and 1,127,220, French Patent No. 2,075,583, and U.S. Patent No. 2,075,583. No. 3.705.8

Known compounds include azole compounds described in U.S. Pat.

However, some of the above compounds have drawbacks such as insufficient coloring properties, the production of other colored substances during the printing process, and the fact that the coloring pigments are unstable to light and heat. Most of them are not put into practical use. Among these,
Azole type has relatively good performance,
It is known that the secondary absorption is small, the shape of the main absorption is sharp, and it is a highly desirable non-J platy in terms of color reproduction.

2,5-diacylaminophenol type cyan couplers are known, as described in No. 46050 and No. 59-166956.

Therefore, by applying the azole magenta coupler and/or the 2,5-diacylaminophenol cyan coupler to a photosensitive material that will become the final image, such as a color reversal film or color photographic paper, excellent color reproducibility can be achieved. It is easy to imagine that color photographic images can be obtained.

However, simply using the azole magenta coupler and/or the 2,5-diacylaminophenol cyan coupler (singly or in combination) does not necessarily result in satisfactory color photographic images (for example, color prints). It wasn't. That is, for example, when the color reproduction gamut of a color photographic paper containing the magenta coupler and the cyan coupler is evaluated by the method described in JP-A No. 59-100440 under constant lightness conditions, it is clear that the color reproduction gamut is However, when printing negatives of actual scenes, it is extremely difficult to reproduce certain colors, such as human skin tones.
Even in the summer, there are problems such as a shift in color balance in highlights and parts of the screen, and certain colors are reproduced in undesirable colors, resulting in the overall color The quality of the photos turned out to be less than stellar as initially expected.

In addition, in some cases, a prototype product that appears to have good color reproducibility even in actual color photography may be obtained, but in most cases, there are certain special conditions (for example, specific It provides desirable color reproduction only under certain conditions (such as development processing, specific exposure conditions, specific viewing conditions, etc.), and has stable high quality under a wide variety of handling conditions required as a product. There was no one there.

In order to solve this problem, as a result of extensive studies, we found that a silver halide containing a yellow dye-forming coupler, using the azole magenta coupler and the 2,5-diacylaminophenol cyan coupler, It is particularly excellent when the ratio of the gamma values when the emulsion diagram, the silver halide emulsion diagram containing the magenta coupler, and the silver halide emulsion diagram containing the cyan coupler are each monochrome-colored is set to a certain value. It was discovered that color reproducibility can be obtained, and the present invention was completed.

[How to determine γ value] The sample after development was processed according to JIS 7612-1982.
Satisfies the geometric conditions for warpage 1 = degree measurement defined by , and has a maximum transmission wavelength of 644 nm for measurement of cyan, magenta, and yellow reflection densities, respectively.

The reflection density is measured using a densitometer having interference filters of 546 nm and 4360 m (half widths of 18 nm or less), and the γ value is calculated using the following formula.

Here, the opposite of the unexposed area! When the lFI concentration is expressed as [) min, El and E2 are respectively Dltlin+ 0
．． It represents the exposure amount required to give a foul density of 5R and Dmin + 1.8.

Cyan γ, magenta γ and yellow γ are defined as follows.

Cyan T2 The γ value was determined by measuring the reflection density of a sample in which a silver halide emulsion diagram containing a cyan coupler represented by the general formula [II] was mainly colored using a 644 nm interference filter of the densitometer.

Magenta Cap A sample colored mainly by a silver halide emulsion decoy containing a magenta coupler represented by the general formula [II] was filtered using the 546 nm interference filter of the densitometer. ) γ value obtained by measuring 1 degree.

The silver halide emulsion containing the yellow coupler represented by the general formula [II] mainly developed color. The γ value was determined by measuring the reflection density of the sample using the 436 nm interference filter of the densitometer.

Here, the above cyan T, magenta γ, and yellow γ
The term "primarily coloring" used in the definition will be explained below. - As an example, consider a silver halide color photographic material having the layer structure shown below.

Consider, for example, the case where the photosensitive material is subjected to monochromatic exposure with red light and developed by the method described above. In this case, ideally only the red-sensitive emulsion in the third layer would be exposed and only the cyan coupler in the third layer would develop color, but in reality, the spectral transmission characteristics of the monochromatic exposure filter and the halogen Due to the spectral sensitivity characteristics of the silveride emulsion, the first
The blue-sensitive emulsion of the layer and the green-sensitive emulsion of the second layer are also sensitive and, correspondingly, the yellow and magenta couplers can also develop color. Furthermore, the red-sensitive emulsion in the third layer is exposed to light,
During color development, a part of the oxidized color developing agent that reacts with the cyan coupler to form a color is transferred to the second layer and the first layer.
The color of the magenta coupler and the yellow coupler can be slightly diffused. For the above reasons, the couplers in the second and third layers may also partially develop color when exposed to red monochromatic light. For the same reason, the cyan coupler in the third layer can also develop color when monochromatic exposure to green light and blue light is performed. In the present invention, the term "primarily coloring" is used to distinguish between these cases. Therefore, taking the above-mentioned photosensitive material as an example, the following relationship is obtained.

Monochromatic exposure to red light → silver halide emulsion containing a cyan coupler mainly develops color Monochromatic exposure to green light → monochromatic exposure to blue light → silver halide emulsion containing a magenta coupler develops mainly color → halide containing a yellow coupler The silver emulsion diagram is mainly colored.The technique of using a specific cyan coupler, a specific magenta coupler, and a specific yellow coupler in combination, which are partially related to the present invention, is described in, for example, JP-A-60-222852 and JP-A-60-229029. Although there are descriptions, all of them are only descriptions regarding the color balance when a dye image fades and the hue of a single dye, and there is no description suggesting the technology for improving color reproducibility by the balance of specific γ values of the present invention.

Next, the relationship between γ value balance and color reproducibility will be described.

Since the balance of γ values is a factor that determines the color balance of a photographic image, it goes without saying that it is necessary that the γ values have an appropriate balance, especially for the reproduction of neutral colors. Therefore, in principle, by appropriately selecting a combination of cyan, magenta, and yellow γ values, a preferable neutral color reproduction can be obtained.

However, selecting a preferable combination of γ values is ``possible in principle,'' and it requires a great deal of effort to actually find a preferable combination, for example, by trial and error. Even if one condition is obtained by chance, that condition may cause diversity in the market, such as differences in processing levels (different processing levels may change the gamma value and/or its balance of the photosensitive material). It is generally known that there is no guarantee that high quality can be maintained even when considering the However, it is not easy.

Therefore, according to the present invention, the cyan coupler, magenta coupler, and yellow coupler according to the present invention are each selected, and the γ values of the light-sensitive silver halide emulsion diagram containing each coupler are independently controlled. However, by forming a multilayer structure having the γ value ratio of the present invention, a silver halide photosensitive material No. 1 having excellent color reproducibility can be obtained, so the merit is very large. .

Furthermore, the silver halide color photographic light-sensitive material according to the present invention has excellent reproduction of neutral colors (not just monochromatic colors).One of the reasons for this is, as mentioned above, color reproduction. Although this is due to the use of a preferred coupler, when we actually produced a prototype based on the present invention, we found that it had much better monochromatic color reproducibility than expected from the effect of the coupler alone. This unexpected effect was found to be
This is probably due to the combination of the couplers of the present invention and the fact that the γ value ratio of each coupler-containing layer is set to a specific value.

In order to produce the silver halide color photographic light-sensitive material according to the present invention, a gradation adjustment technique for each silver halide emulsion diagram is required in order to obtain an appropriate ratio of γ values. Although conventionally used methods can be applied as gradation adjustment techniques, the method described below is preferably used in the present invention.

The basic means of a preferred gradation adjustment method is adjustment using coated silver (2) and coated coupler (5). In general, increasing the amount of silver or coupler applied increases the contrast, and decreasing it decreases the contrast. According to this method, the overall gradation can be adjusted from a low exposure area to a high exposure area.

, Preferred conditions when this method is applied to the present invention are shown in the table below.

More preferable conditions are as shown in the table below, in which the effect of the present invention is more pronounced and manufacturing costs and other properties are taken into consideration.

As an alternative to the basic method of tone adjustment by adjusting the coated silver amount and coated coupler height, another tone adjustment method that is preferably used is to use the yellow, magenta, and cyan couplers according to the present invention. This is a method in which a plurality of types of silver halide emulsions having the same color sensitivity and different sensitivities are mixed and used for each silver halide emulsion diagram contained. In this case, the plural types of silver halide emulsions mentioned above may be mixed and contained in the same emulsion layer, or may be contained separately in a plurality of emulsion layers having the same color sensitivity. Further, a combination of a plurality of silver halide emulsions having the same color sensitivity, substantially the same sensitivity, and different tones may be used.

The above method of adjusting the gradation by mixing a plurality of types of silver halide emulsions can be used in combination with the gradation adjustment method by adjusting the coated silver m and coated coupler 5, to adjust the coated silver amount and coated coupler gate. The range of applications of the method using only gradation adjustment can be further expanded.

In the above method of adjusting gradation by mixing a plurality of types of halogenated i-emulsions, it is preferable to use a monodisperse emulsion, which will be described in detail below, because it enables reliable and easy gradation design.

The gradation adjustment method by adjusting the amount of coated silver and coating coupler forging and the gradation adjustment method by mixing a plurality of types of silver halide emulsions are used alone or in combination as basic means for gradation adjustment, and Ensure that these measures are

In the present invention, gradation adjustment methods other than those described above may be used in combination, if necessary.

Among the above tone adjustment methods, the method of mixing a plurality of types of silver halide emulsions facilitates the tone design of the present invention.

The term "monodisperse emulsion" as used herein refers to a silver halide emulsion consisting of silver halide grains with very small grain-to-grain variations in grain shape, grain size, and silver halide composition. Regarding the particle size distribution, the coefficient of variation defined below is preferably 0.20 or less, and more preferably 0.15 or less, the effect of the present invention becomes more significant.

Here, ri represents the particle size on each side of the particle, and ni represents the particle size.

In the case of spherical silver halide grains, the grain size here means the diameter thereof, and in the case of grains having shapes other than spherical, it means the diameter when the projected image is converted into a circular image of the same area.

That's true. The lower the silver iodide content, the better from the viewpoints of developability and desilvering properties.Especially in green-sensitive silver halide emulsions and red-sensitive silver halide emulsions, blue light sensitivity is kept low and color reproducibility is improved. It is better to lower the silver iodide content by taking into account that the silver iodide content will be better, and for the same reason, the higher the Jg silver iodide content in green-sensitive silver halide emulsions and red-sensitive silver halide emulsions, the higher the Jg silver iodide content. preferable.

Regarding the layers, yellow coupler, magenta coupler, cyan coupler, and coated silver m were set to the conditions shown in Table 6 below, and other conditions were the same as Sample 15, and Comparative Samples 16 to 24 were prepared.
Samples 25 to 27 according to the present invention were prepared. However, for the first layer of sonic emulsion, when the amount of coated silver was changed, both EMB-3 and EMB-4 @
The maximum sinkage was always constant.

Example 1 for Samples 15 to 27 thus obtained
Using the same method as above, determine the γ value in monochrome exposure, and calculate the ratio (Y/C) of the γ value of the yellow coupler-containing layer to the γ value of the cyan coupler-containing layer, and the ratio of the γ value of the magenta coupler-containing layer to the γ value of the cyan coupler-containing layer.

From Table 6, the following can be said. That is, in contrast to Comparative Sample 15 in which yellow, magenta, and cyan couplers were all used as comparative couplers, in Comparative Samples 1116 to 19 in which at least one of yellow, magenta, and cyan couplers was used as a coupler according to the present invention. Color reproducibility has improved, although it cannot be said to be sufficient. Furthermore, if we focus on the ratio of γ values specified in the present invention, even comparative samples 15 to 18, which satisfy the γ value, have insufficient color reproducibility, and furthermore, the yellow, magenta and Even if each cyan coupler is used, the color reproducibility is similarly insufficient in Samples 19 to 24, which do not satisfy the ratio of γ values defined in the present invention. On the other hand, in Samples 25 to 27, which used the yellow, magenta, and cyan couplers according to the present invention and also satisfied the γ value ratio specified in the present invention, the color reproducibility was further improved. I understand.

From the above, the effect of improving color reproducibility according to the present invention can be obtained mutually by using the cyan, magenta, and yellow couplers according to the present invention together and by setting a specific γ value ratio. It can be seen that it is effective.

Example 4 In order to visually confirm the effects of the present invention on actual puddings 1 to 1, the sample prepared in Example 3 was coated with a color negative film that retained the shape of the actual scene (brightness and color tone Photograph several different subjects with 4 Nokura Color 5R100
(and which were exposed using Konica FS-1 and subjected to predetermined development processing) were visually evaluated for blinting, neutral color, and monochromatic reproducibility according to the evaluation criteria described below. The results are shown in Table-7.

Evaluation criteria Grade Contents ◎　　　It is very well reproduced.

○ Favorably reproduced.

△　　　This is a somewhat unsatisfactory reproduction.

× This is an unfavorable reproduction.

In addition, when printing, please use Sakura Color Printer 5N.
-2, and a color vapor developer process CPK-18 (manufactured by Konishiroku Photo Industry Co., Ltd.) was used for the development.

Table 7 From Table 7, it can be seen that Samples 25 to 27 according to the present invention are all excellent in color reproducibility of both neutral colors and single colors, and the effects of the present invention can be fully confirmed by visual observation of prints during practical training. You can see that it can be confirmed. That is, it can be seen that the silver halide H-color photographic light-sensitive material using the present invention can reproduce 111 colors more vividly, and can provide color photographs with no loss of color balance in neutral colors.

Example 5 Comparative samples 28 to 30 and samples rA and 31 to 42 of the present invention were prepared by changing the cyan, magenta and yellow couplers of the sample prepared in Example 3 as shown in Table 8 below. . Incidentally, the coated silver is suitably JJ-faced so that the ratio of γ values falls within the range defined by the present invention.

Next, for the samples 28 to 42, the γ values were determined in the same manner as in Example 3, and the color reproducibility was evaluated.

The results are also shown in Table-8.

The following margin is for comparison magenta coupler CN1-2 used in Table 8.
The JPI construction of is as follows.

(CM-2) From Table 8, Samples 31 to 42 according to the present invention are Comparative Sample 2
It can be seen that all have excellent color reproducibility compared to numbers 8 to 30. In addition, among the try-on samples of the present invention, samples 39 to 4
2, it can be seen that in the present invention, it is more preferable to use a cyan coupler of the general formula [rV ] in addition to the cyan coupler of the general formula [II1].

Example-6 Using C-29 and C-36 as cyan couplers, 59 as magenta coupler, and Y-31 as yellow coupler, coated silver 2 was adjusted so that the γ value fell within the range specified by the present invention. The rest is Example-5.
Sample FI43 was prepared in the same manner as sample 41.

Next, in the third decoy green-sensitive emulsion, the amount of the compound of general formula [V] (example No. 13) at the end of chemical ripening is reduced to Omg and 10IB per mole of silver halide, respectively. EMG-2 obtained in the same manner as EMG-1 except for
Samples 44 and 45 were prepared using Sample 43 and EMG-3, respectively, and using Sample 43 and the bacterial strain under other conditions.

Next, Sample 46 was prepared in the same manner as Sample 45, except that the compound of general formula [V] (Example No. 13) was added to the fourth layer so that the coating opening was 0.018 m (1/i'). did.

Next, a compound of the general formula [■] in the third layer (Example No. 4>
are respectively Om(+/Tl12 and 0.02(1/v
Samples 47 and 48 were prepared in the same manner as sample 43, except that +' was used.

Next, a compound represented by the general formula [VII] (Example No. 3) is further coated on the third layer to give a coating density of 0.005!1/f.
Sample 4 was prepared in the same manner as sample 43 except that it was added so that
9 was created.

Regarding the samples 43 to 4 prepared above, the γ value and color reproduction range were evaluated by the method described in Example-1, and the neutral color reproducibility was evaluated by the method described in Example-4. The results are shown in Table ○.

From Margin Table 9 below, it can be seen that in Samples 45, 46, 48 and 49, the color reproducibility was even more preferable because the auxiliary gradation adjustment technique described in this specification was used.

On the other hand, a compound represented by the general formula [V], a compound represented by the general formula [
Samples 44 and 47, which do not use the compound represented by [VI] or the compound represented by general formula [VII], are excellent in color reproduction range, but are somewhat dissatisfied with neutral color reproduction in the low density range.

In addition, tests were also conducted on other photographic properties for the seven samples 43 to 49 mentioned above, and it was found that active developers (for example, those with reduced potassium bromide in color developers) When testing the fog resistance and light stability of the dye image (evaluated under sunlight for 30 days), samples 44, 45 and 47 showed good fog resistance with active developer, and sample 48 showed no brightness. However, there was no problem at all with Sample 46 and Sample 4c3, although the storage stability of the dye images tended to deteriorate slightly compared to Sample 43. In this way, by using the gradation adjustment technology mentioned in the description in a timely manner, gradation design becomes easy and color reproducibility is not only improved, but also silver halide photographs that are excellent in other photographic characteristics are produced. It can be seen that a photosensitive material can be obtained.
