It is expressed as (Φ./Φ). Φ. is the illumination light flux for density measurement, and Φ is the transmitted light flux of the part to be measured.

The geometric conditions for concentration measurement are that the illumination light flux is parallel light flux in the normal direction, and that the total light flux that is transmitted as a transmitted light flux and diffused in a half space is used.When using other measurement methods, the standard Perform correction using density pieces. Further, during measurement, the emulsion film surface shall face the light receiving device side. The density measurement is performed at status M density of blue, green, and red, and the spectral characteristics are set to the values shown in Table B as the comprehensive characteristics of the light source, optical system, optical filter, and light receiving device used in the densitometer.

The exposure amount corresponding to a high density is expressed in lux/seconds as HB, H, and HA, respectively.

■ The larger value (lower sensitivity) of HB and HA is designated as H.

■ Calculate the specific photographic sensitivity S according to the formula below.

(5) Determination of specific photographic sensitivity The photographic material of the present invention is processed under the conditions shown in (1) to (4) and uses the results of density measurement to determine the specific photographic sensitivity according to the following procedure. The specific photographic sensitivity determined by the method is 80 or more and less than 320. If it is less than 80, the probability of out-of-focus due to the aperture opening during normal shooting, the probability of camera shake due to slow shutter speed, and the probability of underexposure increase, increasing the failure rate. Also, the latest camera is D
Many cameras have an automatic sensitivity setting function by reading the It cannot be applied to these cameras unless the sensitivity is at least 80 or higher. Furthermore, if the specific photographic sensitivity is set to 320 or more as described in JP-A No. 63-226651, deterioration in graininess becomes noticeable especially when the magnification is increased, which is not preferable.

The amount of silver contained in the photosensitive material of the present invention is 1. Og/
rd or more and 4.9 g/m2 or less. Conventionally, the sensitivity was 10
In order to maintain graininess to some extent in commercially available color negative films with a silver content of 5.0 g/n or more, the silver content is 5.0 g/n.
It was more than f. However, if the silver content exceeds 5.0 g/rd, after two years, which is the general expiration date for color negative films, granular deterioration will occur due to exposure to natural radiation to the extent that it becomes a practical problem. Such things include a sensitivity of 320 or more and a silver content of 8. Og/rr? Although it was already clear in the above color negative films as described in JP-A No. 63-226651, it has become clear that even in the sensitivity and silver content ranges of the present invention, there is a big problem. Further, although it was expected to some extent that the sharpness would be improved by reducing the silver content to 4.9 g/m2 or less, the degree of improvement was far greater than expected. The reason why sufficient color density and sensitivity can be obtained with such a light-sensitive material having a low silver content is due to the use of the compound represented by the general formula (I) of the present invention.

The compound of the present invention suppresses the color density of the added color-sensitive layer to a lesser extent than conventional so-called DIR couplers (DIR compounds), and can effectively suppress the color density of other color-sensitive layers. It is possible.

In other words, the so-called interlayer effect (multilayer effect) is large (
Journal of the Photographic Society of Japan, Vol. 52, pp. 145-149 (1989))
. Therefore, in order to improve color reproducibility, conventional DIR
A large amount of coupler needs to be added, and as a result, the coloring density of the added layer decreases, and a photosensitive material with a low silver content, such as the one of the present invention, cannot obtain a sufficient density. On the other hand, the general formula of the present invention (
By using the compound represented by I), it has become possible to obtain a sufficient interlayer effect with a low silver content and to obtain a light-sensitive material with excellent color reproducibility.

The silver content of the photosensitive material of the present invention is preferably 1.0 g.
/m2 or more 4.6g/resistant, more preferably 1.0g
/a or more and 4.3g/m2 or less, more preferably 1.5
g/m2 or more and 4.0 g/rd or less.

The silver content referred to here is the content of all silver such as silver halide and metallic silver converted into silver. Several methods are known for analyzing the silver content of photosensitive materials, and any method can be used.
The line method is simple.

The light-sensitive material of the present invention each has at least one red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a blue-sensitive silver halide emulsion layer, but any emulsion layer having the same color sensitivity can be used for sensitivity. It is preferable that the emulsion layer is composed of two or more emulsion layers having different values, and it is more preferable to use a method for further improving graininess in a three-layer structure. These techniques are described in British Patent No. 923.045 and Japanese Patent Publication No. 49-15495, respectively.

In color negative photographic materials, when an emulsion layer of the same color sensitivity is composed of two or more emulsion layers with different sensitivities, the silver content of the emulsion layer with higher sensitivity is lowered to take advantage of the so-called granularity disappearing effect. It was common sense to design a large number of color negative photographic materials with high image quality. However, in high-sensitivity color negative photographic materials with a specific photographic sensitivity of 80 or more and less than 320, increasing the silver content in the emulsion layer with higher sensitivity (this results in better preservation than increasing the silver content in the emulsion layer with lower sensitivity) It was found that it has an unexpected drawback of large deterioration over time.Therefore, it is preferable not to increase the silver content of the emulsion layer with the highest sensitivity among emulsion layers of the same color sensitivity.Red The silver content of the most sensitive emulsion layer of each of the sensitive layer, green sensitive layer, and blue sensitive layer is preferably 0.3 g/a or more and 1.2 g/a or less,
More preferably 0. 3g/m2 or more and 1.0g/rd or less, more preferably 0.3g/m2 or more and 0.8g/r
d or less.

Furthermore, various inventions regarding the order of layer arrangement have been made in order to achieve both high sensitivity and high image quality. A combination of these techniques may also be used. The invention regarding the order of layer arrangement is
For example, U.S. Pat. No. 184.876, 4.1
No. 29.446, No. 4°186.016, British Patent No. 1. 560. No. 965, U.S. Patent No. 4,186,0
No. 11, No. 4゜267.264, No. 4.173,47

No. 77552, British Patent No. 2.137,372, Japanese Patent Application Laid-open No. 59-180556, Japanese Patent Application Publication No. 59-204038, etc.

Furthermore, a non-photosensitive layer may be present between two or more emulsion layers having the same color sensitivity.

A reflective layer such as fine-grain silver halide may be provided under the high-speed layer, particularly the high-speed blue-sensitive layer, to improve sensitivity. This technique is described in Japanese Patent Application Laid-Open No. 59-160135.

Generally, the red-sensitive emulsion layer contains a cyan-forming coupler, the green-sensitive emulsion layer contains a magenta-forming coupler, and the blue-sensitive emulsion layer contains a yellow-forming coupler, but different combinations may be used depending on the case. For example, it may be used in combination with an infrared-sensitive layer for pseudo-color photography or semiconductor laser exposure.

Also, U.S. Patent No. 3,497,350 or Japanese Patent Application Publication No. 5
As described in No. 9-214853, it is also possible to use a method in which the color sensitivity of the emulsion layer and a color image-forming coupler are appropriately combined and this layer is provided at the farthest position from the support.

Any of silver bromide, silver iodobromide, silver iodochlorobromide, silver chlorobromide and silver chloride may be used as silver halide in the photographic emulsion layer of the silver halide photographic light-sensitive material of the present invention. A preferred silver halide is silver iodobromide containing up to 30 mole percent silver iodide. Preferred is silver iodobromide containing from 2 mole % to 20 mole % silver iodide.

In the present invention, in order to achieve both low silver content and high image quality, the silver halide content of all emulsion layers must be 5.6 mol%.
It is particularly preferable to do the above.

In the present invention, the average silver iodide content of silver halide in all emulsion layers is defined as the total iodine content divided by the total silver halide content (not including metallic silver) present in the light-sensitive material, which is 100. It is the value multiplied by In the present invention, this average silver iodide content is 5.
The content is preferably 6 mol% or more, more preferably 6.0 mol% or more and 15 mol% or less, and even more preferably 7.0 mol% or more and 12 mol% or less.

It is known that graininess can be improved by increasing the average silver iodide content of silver halide, but on the other hand, there are disadvantages such as slow development speed, desilvering, and slow fixing speed (for example, As described in Kaisho 62-89963)
come out. However, the present inventors have found that these drawbacks do not become a problem when the amount of silver contained is reduced as in the present invention, the sensitivity is specified, and the compound represented by the general formula (I) of the present invention is used. Ta.

02 to 0.2 μ- is more preferable.

Fine-grain silver halide can be prepared in the same manner as ordinary photosensitive silver halide. In this case, the surface of the silver halide grains does not need to be optically sensitized, nor is spectral sensitization necessary. However, prior to adding this to the coating solution, it is preferable to add in advance a known stabilizer such as a triazole-based, azaindene-based, benzothiazolium-based, or mercapto-based compound, or a zinc compound.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. In this black and white developer, known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as -phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol are used alone or Can be used in combination.

These color developing solutions and black and white developing solutions generally have a pn of 9 to 12. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material being processed, but in general it is 31 or less per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher, it can be increased to 500 or less.
It can also be less than d. When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank.

The contact area between the photographic processing solution and air in the processing tank can be expressed by the aperture ratio defined below.

That is, the above aperture ratio is preferably 0.1 or less, more preferably 0.001-0.05. As a method for reducing the aperture ratio in this way, in addition to providing a shield such as a floating lid on the surface of the photographic processing liquid in the processing tank,

-5, specifically acetic acid, propionic acid, etc. are preferred.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, 1,000-onythyl compounds, thioureas, and large amounts of iodide salts, but thiosulfates are generally used. ammonium thiosulfate is the most widely used.

Furthermore, various aminopolycarboxylic acids and phosphonic acids are preferably added to the fixing solution and bleach-fixing solution for the purpose of stabilizing the solution.

The total time for the desilvering process is preferably as short as possible without causing desilvering defects.The preferred time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes. In addition, the processing temperature is 25°C ~
50°C, preferably 35°C to 45°C. In a preferred temperature range, the desilvering rate is improved and the occurrence of staining after processing is effectively prevented.

In the desilvering process, it is preferable to strengthen the stirring as much as possible.A specific method for strengthening the stirring is to impinge a jet of processing liquid on the emulsion surface of a photosensitive material as described in JP-A-62-183460. Method and JP-A-624834
A method of increasing the stirring effect by using the rotating means of No. 61, and further improving the stirring effect by moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid to create turbulence on the emulsion surface. Examples include a method of increasing the circulation flow rate of the entire treatment liquid. Such means for improving agitation is effective for all bleaching solutions, bleach-fixing solutions, and fixing solutions. It is believed that improved stirring speeds up the supply of bleach and fixing agent into the emulsion film, and as a result increases the desilvering rate. Further, the agitation improving means described above is more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect caused by the bleach accelerator.

The automatic developing machine used for the photosensitive material of the present invention is
No. 0-191257, No. 60-191258, No. 60
It is preferable to have a photosensitive material conveying means as described in Japanese Patent Laid-open No. 191259-1912. This effect is particularly effective in shortening the processing time in each step and reducing the amount of processing solution replenishment.

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
urn-al of the 5ociety of
Motion Picture and Te1evi
sion Engineers Volume 64, P, 248
-253 (May 1955 issue).

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

The washing water temperature and washing time can also be set in various ways depending on the characteristics of the photosensitive material, its use, etc., but generally it is in the range of 20 seconds to 10 minutes at 15 to 45°C, preferably 30 seconds to 5 minutes at 25 to 40°C. is selected. Furthermore, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water.

In such stabilization treatment, Japanese Patent Application Laid-Open No. 57-854
All known methods described in No. 3, No. 58-14834, and No. 60-220345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be carried out. For example, a stabilization bath containing a dye stabilizer and a surfactant, which is used as a final bath for a color photosensitive material for photographing, may be further carried out. Examples of the dye stabilizer that can be mentioned include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetramine, and aldehyde sulfite adducts.

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The overflow liquid from water washing and/or replenishment of the stabilizing liquid can be reused in other processes such as the desilvering process.

When each of the above-mentioned processing liquids is concentrated by evaporation in processing using an automatic processor or the like, it is preferable to correct the concentration by adding water.

The silver halide color light-sensitive material of the present invention may contain a color developing agent for the purpose of simplifying and speeding up processing. In order to incorporate a color developing agent, it is preferable to use various precursors of the color developing agent. U.S. Patent No. 3,342,59

(Sample 108) Sample 108 was prepared by changing the amount of gelatin in the third layer of sample 107 to 1.2 g/d and the amount of gelatin in the fourth layer to 1.6 g/m2.

(Sample 109) The coupler (C-7) in the third and fourth layers of sample 108 was
Sample 1 was prepared by replacing (C-10) in the fourth layer with EX-2 in X-4 and replacing (C-34) in the fifth layer with EX-14 in equimolar amounts.
It was set as 09.

(Sample 11O) Sample 110 was prepared by changing the gelatin in the third layer of sample 109 to 2.0 g/m2 and the gelatin in the fourth layer to 2.3 g/lrr.

Table 2 shows the silver content and average silver iodide content of these samples. Further, the specific photographic sensitivity defined in the present invention was determined and shown in Table 2. Further, after uniformly irradiating the sample with X-rays (200 kV, 3 seconds), specific photographic sensitivity was measured. Similar processing is performed for sharpness, and the conventional MTF (Modul
tion Transfer Function) method, and expressed as a relative value with the MTF value of a cyan image of 20 cycles/mm immediately after the creation of sample 101 as 100.

In addition, these samples were subjected to the same development process to obtain a specific photographic sensitivity, except that 40 lux·sec of white light was applied and the bleaching times were changed to 1 minute 30 seconds, 2 minutes, and 30 minutes, and the magenta density was measured. I did it.

Bleach time 1 minute 30 seconds and magenta density 2 minutes to 30
Table 2 shows the value obtained by subtracting the concentration by 100 min as the defective desilvering concentration.

Furthermore, five scratches with a depth reaching the support from the emulsion side of these samples were made with a commercially available knife at 3.5mm x 14mm.
After sufficient adhesion with commercially available cellophane tape, the tape was removed and peeling of the emulsion film was observed.

From Table 2, the samples of the present invention exhibit X when exposed to natural radiation.
While the decrease in sensitivity due to radiation irradiation is small, samples 105 and 106 with silver contents outside the present invention have a large decrease in sensitivity (
In addition, despite the large amount of silver, the decrease in sensitivity after X-ray irradiation is low, the samples of the present invention have excellent sharpness expressed by the MTF value, and even if the bleaching time is short, the concentration of defective desilvering is low; Excellent silver properties (can be processed in a short time)
is clear.

Further, it is clear that the sample using the preferred cyan coupler of the present invention has less film peeling and is superior in sharpness and desilvering property compared to sample 109.110 in which the cyan coupler is not used.

Example 2 (Samples 201 to 202) Sample 201 was prepared by increasing the emulsion density of the fourth layer of sample 101 to 1.32 times and the emulsion A of the fifth layer to 1.4 times, and increasing the emulsion density to 0.8 times.
Sample 202 was prepared by multiplying Emulsion A by 0.75 times.

~226 were produced.

The specific photographic sensitivity of these samples was determined in the same manner as in Example 1.

Further, X-ray irradiation (120 kV, 2 seconds) was performed, and Table 3 shows the relative sensitivity decrease in cyan density (fog +0.15).

Furthermore, a similar color development process was performed with an exposure amount of 5 lux·sec, and the cyan density was measured.

Further, imagewise exposure was performed through a red filter, and the value obtained by subtracting the magenta fog density from the magenta density in exposure I, which gave a cyan density of (fog + 1.0), was determined as the color turbidity density.

Further, the MTF value was also determined in the same manner as in Example 1.

From Table 3, the samples of the present invention use the compounds of the present invention, and have less decrease in sensitivity due to X-ray irradiation (and lower sharpness expressed by MTF value) than samples with high silver content (201, 203, 206). It has a lower color turbidity density than the samples (209-217) not using the compound of the present invention, excellent color reproducibility and excellent sharpness, and the sample (218-226) not using the compound of the present invention. Compare 5 lux
It is clear that the color density is high at an exposure amount of seconds.

Example 3 Samples 301 to 304 were prepared by replacing the emulsion formulas of the 5th layer, 9th layer, and 13th layer of Samples 101 and 103 with Emulsion F and Emulsion G prepared according to the method for preparing Emulsion A. These samples were processed into 135 cartridge size, and taken outdoors under clear skies using a Fuji Photo Film ■ camera Chaldea Bite, half-body portraits of motherhood, half-length portraits of two men and women, full-length portraits of two men and women, distant views of buildings, and distant views of mountains. Photographed.

These photographed photosensitive materials were subjected to the following color development process.

The processing solutions used were Super HR ■-100 which had been subjected to standard exposure and which had been processed until the replenishment amount of each solution was three times that of the mother solution tank (Champion 23S automatic processor).

A standard treatment was performed.

Ten men and ten men and women were asked to monitor and evaluate whether each of these prints was acceptable as a print.

Table 4 From Table 4, prints obtained from either sample are acceptable in most scenes at 3x magnification. When magnified by 10 times, it can be seen that the higher the average silver iodide content, the higher the tolerance.

Example 4 (Sample 401) EX-16 was added to the 14th layer of Sample 104 at 0.21 g/go,
Sample 401 was prepared by adding 0.31 g/day of EX-17.

(Sample 402) Emulsions A to D used in Sample 104 were each made larger in size to prepare Emulsions HK, and Emulsions A to D in Sample 104 were replaced to form Sample 402.

(Sample 403) From sample 403, emulsions H-K of the photosensitive emulsion layer were each 1.
Sample 403 was obtained by multiplying the size by 6 times.

The specific photographic sensitivity of these samples was determined in the same manner as in Example 1. Further, the cyan color density was determined in the same manner as in Example 2 at an exposure dose of 5 lux·sec.

Furthermore, these samples were processed into 135 size cartridges,
A monitor test similar to Example 3 was conducted.

After each sample was uniformly exposed to light at 0.02 lux·sec, the emulsion surface of each sample was scratched at a speed of 5 cm per second while applying a load of 4 g using a sapphire needle with a radius of approximately 30 μm at the tip. Ta. Subsequently, the film was developed in the same manner as in the measurement of specific photographic sensitivity. The magenta density of the scratches caused by scratching with the needle was measured using a microdensitometer, and the difference in density from the scratched area was determined.

From Table 5, it can be seen that sample 401 with a sensitivity of 66 has low tolerance as a print. This is due to underexposure due to insufficient sensitivity.

Further, since sample 402 was made to have high sensitivity, the color density was extremely low as can be seen from the low cyan density at 5 lux·sec, and there was almost no printing tolerance. Sample 403
Although the silver content was increased compared to 402 in order to increase the color density, the sensitivity to X-ray irradiation was extremely low, and the graininess was coarse, so the printing tolerance was also low.
