Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color reversal photographic light-sensitive material having excellent sharpness and color reproducibility and improved desilvering properties.

(Prior art) Silver halide power 2-reversal photographic effect''lt, the material is photographed and developed so that the photosensitive material itself can be viewed as a positive image.
Used for printed manuscripts, etc. In particular, in recent years, printed manuscripts are often enlarged from smaller formats to higher magnifications, and are required to have excellent sharpness and graininess, as well as more vivid color reproducibility.

To improve the image quality and color reproduction of silver halide color reversal photographic materials, change the shape of silver halide (e.g. use of monodisperse emulsion, use of tabular emulsion), adjust the y'n composition, or Attempts have been made to control the distribution of halogen ions.

In addition, in order to adjust the spectral sensitivity, methods such as the development of sensitizing dyes and the addition of dyes 710 have been carried out, but there is a need for the development of even more useful techniques. In the case of color negative photosensitive materials, DIR, which releases a development inhibitor during the color development process,
Coupler is used to improve image quality, color reproduction, etc. However, with reversal color photosensitive materials, there is a problem with B/W development at the beginning of the processing process, and there are limits to adjustment using couplers. be.

Using this B/W development Sharpness of silver halide reversal color negative light-sensitive materials.

As a technique for improving color reproduction, it is known to use DIR-hydroquinones, which release a development inhibitor during the development process and suppress development (U.S. Watch No. 3372!22, U.S. Special Fl'jAJji'#77). , Tokukai Showφter/J5'
jJ4). However, although the use of DIE (-hydroquinones) is useful for improving image quality and color reproduction, the released development inhibitors bleach the developed silver and delay desilvering during fixing, resulting in The developed silver tends to remain and cause problems with blackish brown stains, which limits the way it can be used.

Furthermore, as a technique for improving the desilvering properties, a method has been attempted in which colloidal silver that tends to remain after processing, that is, yellow colloidal silver for yellow filters and black colloidal buttons for antihalation layers, is dyed.

For example, mordant technology using basic polymers and acidic dyes (U.S. Patent No. 2z4Lrztx, U.S.%i!/, 24'316
No. FF162!6Y'1 in the U.S.), a method for use on oil-soluble dyes that decompose and elute into the processing solution or decolorize by reaction with subtJk ions in the processing solution (IFl: 4 in the U.S.)
t4t20! ! ! , JP-A-67-2θ←120% JP-A-62-K2λ2gt), etc. were attempted. However, these methods have the disadvantage that they cannot fully suppress the diffusivity of the dye, causing a decrease in the sensitivity of other layers, or they cannot completely decolorize, resulting in color staining of white background areas. However, a method has been discovered in which the dye is added as a microcrystalline dispersion.

ω-51) OH The compound represented by the general formula (vlL':1) can generally be synthesized by the following two methods. When Time is a simple bond (t-0), the first is chloroform or In L2-dichloroethane, carbon tetrachloride, tetrahydrofuran, benzoquinone, orthoquinone, quinone in the absence of a catalyst or in the presence of an acid catalyst such as Fi, p-)luenesulfonic acid, benzenesulfone fI/, )lifluoromethanesulfonic acid, methaisulfonic acid, etc. This method involves reacting a monoimine or quinone diimine derivative with a development inhibitor at a temperature between room temperature and 100°C. The second is benzoquinone, orthoquinone substituted with chlorine, bromine or iodine in the presence of a base such as potassium carbonate, sodium bicarbonate, sodium hydride, triethylamine in an aprotic polar solvent such as acetone, tetrahydrofuran, dimethylformamide, etc. A method in which a quinone compound obtained by reacting a quinone monoimine, a quinone diimine derivative, and a development inhibitor at a temperature between -20°C and 100°C is reduced with a reducing agent such as diethyl hydroxylamine, hydrosulfite, etc. [Reference: Re5earch Disc

can also be synthesized in almost the same manner as above. In other words, Time-X is used as the base of the development inhibitor (X), or T having a group that can be substituted with XIC (for example, a halogen atom, a hydroxyl group, or a precursor thereof)
This is a method in which ime is first introduced into a redox mother nucleus, and then X is linked through a substitution reaction.

The amount of the compound represented by the general formula of the present invention is in the range of 10-5 to 10-1 mol, preferably 10-4 to 10-2 mol, based on the silver halide of the layer to which it is added.

The compound represented by the general formula of the present invention may be used alone, or 28! It may be used in combination with more than one class.

The compound represented by the general formula may be added as an emulsion obtained by dissolving in a high-boiling oil and stirring at high speed, or by adding an additive to a gelatin solution dissolved in a water-soluble organic solvent such as alcohol or cellosolve with stirring. It may be added in finely dispersed form.

The light-sensitive material of the present invention only needs to have at least one silver halide emulsion layer of a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer on the support. There are no particular limitations on the number and order of layers and non-photosensitive layers. A typical example is a silver halide photographic material having on a support at least one photosensitive layer consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities. The photosensitive layer is a unit photosensitive layer sensitive to blue light, green light, or red light, and in a multilayer silver halide color photographic light-sensitive material, the photosensitive layer is generally a unit photosensitive layer. A red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer are arranged in this order from the support side. However, depending on the purpose, the order of installation may be reversed, or the order of installation may be such that different photosensitive layers are sandwiched between the same color-sensitive layer.

Non-photosensitive layers such as various intermediate layers may be provided between the silver halide photosensitive layers and between the uppermost layer and the lowermost layer.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.
No. 13438, No. 59-113440, No. 61-20
Coupler, DIR compound, etc. as described in No. 037 and No. 61-20038 may be included,
It may also contain a commonly used color mixing inhibitor.

A plurality of silver halide emulsion layers constituting each unit photosensitive layer are composed of a high-speed emulsion layer and a low-speed emulsion layer, as described in West German Patent No. 1,121,470 or British Patent No. 923,045. A two-layer configuration can be preferably used.

Usually, it is preferable to arrange the layers so that the photosensitivity decreases toward the support, and a non-photosensitive layer may be provided between each halogen emulsion layer.
No. 112751, No. 62-200350, No. 62-2
As described in Nos. 06541 and 62-206543, a low-sensitivity emulsion layer may be provided on the side far from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

As a specific example, from the side farthest from the support: low sensitivity blue sensitive layer (BL) / high sensitivity blue sensitive layer (BH) / high sensitivity green sensitive layer (GH) / low sensitivity green sensitive layer (GL) /High-sensitivity red-sensitive layer (RH) /Low-sensitivity red-sensitive layer (RL)
They can be installed in the order of BH/BL/GL/IJ/RH/RL, or the order of BH/BL/GH/GL/RL/RH.

Further, as described in Japanese Patent Publication No. 55-34932, from the side farthest from the support, the blue-sensitive layer/Gll/
They can also be arranged in the order of RH/GL/RL. Alternatively, as described in JP-A-56-25738 and JP-A-62-63936, the blue-sensitive layer/GL/RL/GH/RH can be arranged in this order from the farthest side from the support. .

In addition, as described in Japanese Patent Publication No. 49-15495, the upper layer is a silver halide emulsion layer with the highest sensitivity, the middle layer is a silver halide emulsion layer with lower sensitivity, and the lower layer is more sensitive than the middle layer. An example is an arrangement consisting of three layers with different photosensitivity, in which a silver halide emulsion layer with a low density is disposed and the photosensitivity gradually decreases toward the support. Even when it is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464,

Next, processing solutions and processing steps for the color reversal photosensitive material of the present invention other than the color developing solution will be explained.

Among the processing steps for the color reversal photosensitive material of the present invention, the steps from black development to color development are as follows.

■) Black and white development - water washing, reversal, one color development 2) Black and white development - water washing, light reversal, one color development 3) Black and white development - water washing, one color development process The water washing steps 1) to 3) are all based on U.S. Patent Nos. 4 and 8.

The above steps l) to 3
) and any one of the steps 4) to 15) are connected to form a color reversal step.

Next, the processing liquid for the color reversal processing step of the present invention will be explained.

Known developing agents can be used in the black and white developer used in the present invention. As developing agents, dihydroxybenzenes (e.g. hydroquinone), 3-pyrazolidones (e.g. 1-phenyl-3-pyrazolidone),
Aminophenols (e.g. N-methyl-p-aminophenol), 1-phenyl-3-pyrazolines, ascorbic acid and the 1,2,3,4-tetrahydroquinoline ring described in U.S. Pat. No. 4,067,872. Heterocyclic compounds such as a condensation of and an intrene ring can be used alone or in combination.

The black and white developer used in the present invention may also include preservatives (e.g. sulfites, bisulfites, etc.), buffers (e.g. carbonates, boric acid, borates, alkanolamines), alkaline agents (e.g. oxides, carbonates), dissolving tablets (e.g. polyethylene glycols, esters thereof)
, pH1 adjuster (for example, organic acid such as acetic acid), sensitizer (
For example, it may contain a quaternary ammonium salt), a development accelerator, a surfactant, an antifoaming agent, a hardening agent, a viscosity imparting agent, and the like.

The black and white developer used in the present invention must contain a compound that acts as a halogenated solvent, and the sulfite added as a preservative as described above usually plays this role. Specifically, silver halide solvents that can be used include KSCNNa SCN, 2SO3,N
azSOi, KzSzOsNazszOs, K15
20. , NazSz○3, etc.

The pH value of the developer thus adjusted is selected to be sufficient to provide the desired density and contrast, but is in the range of about 8.5 to about 11.5.

In order to carry out sensitization using such a black and white developer, it is usually sufficient to extend the time up to about three times as long as the standard processing. If the treatment temperature is raised at this time, the extension time for the sensitization treatment can be shortened.

The p)I of these color developing solutions and black and white developing solutions is 9 to 12.
It is common that The amount of replenishment of these developers depends on the color photographic light-sensitive material being processed, but it is generally less than 3i per square meter of light-sensitive material, and by reducing the bromide ion concentration in the sleeve solution,
It can also be set to 0d or less. 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-mentioned aperture ratio is preferably 0.1 or less, more preferably o.ooi to 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,
Method using a movable lid described in No. 033, JP-A-63
The slint development method described in Japanese Patent No.-216050 can be mentioned. Reducing the aperture ratio is important not only for both color development and black and white development processes, but also for subsequent processes,
For example, it is preferable that it can be used in all steps such as bleaching, bleach-fixing, fixing, washing with water, and stabilization. Furthermore, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developer.

The reversal bath used after black and white development can contain a known fogging agent. Namely, stannous ion-organophosphoric acid complex salt (U.S. Pat. No. 3,617゜282), stannous ion-organophosphonocarboxylic acid complex salt (Japanese Patent Publication No.
-32616 Publication) Stannous ion-aminopolycarboxylic acid complex salt (U.S. Patent No. 1.209,050)
stannous ion complex salts such as borohydride compounds (US Patent No. 2,984,567), heterocyclic amine borane compounds (UK Patent No. 1,011,000)
The pH of this fogging bath (reversal bath) ranges widely from the acidic side to the alkaline side, with a pH of 2 to 12, preferably 2.5 to 10.
, particularly preferably in the range of 3 to 9. In place of the reversal bath, a light reversal process may be performed by re-exposure, and the reversal step can also be omitted by adding the above-mentioned fogging agent to the color developing solution.

The silver halide color photographic material of the present invention is subjected to a bleaching treatment or a bleach-fixing treatment after color development. These treatments may be performed immediately without going through the color developing agent processing step, or in order to prevent unnecessary post-development and air fog, and to reduce the carry-over of the color developer into the desilvering process. In addition, in order to wash out and detoxify the sensitive material parts such as sensitizing dyes and dyes contained in the photographic light-sensitive material and the color developing agent impregnated in the photographic light-sensitive material, after the color development process, stopping, adjustment, washing with water, etc. After passing through the treatment steps, a bleaching treatment or a bleach-fixing treatment may be performed.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process (bleach-fixing process) or separately, or in order to speed up the process, a bleach-fixing process may be performed after the bleaching process. Furthermore, treatment with two consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment can be carried out as desired depending on the purpose. Examples of bleaching agents that can be used include compounds of polyvalent metals such as iron (III), peracids, quinones, and nitro compounds. Typical bleaching agents include organic complex salts of iron ([[[), such as ethylenediamine tetra Aminopolycarboxylic acids such as acetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-cyanopropanetetraacetic acid, glycol ether cyanotetraacetic acid, or citric acid, tartaric acid, malic acid, etc. Complex salts etc. can be used. Among these, aminopolycarboxylic acid iron (I[I) complex salts, including iron ethylenediaminetetraacetate (l[IH! salt and 1,3-diaminopropanetetraacetic iron cm) if salt, are suitable for rapid processing and prevention of environmental pollution. Preferable from the viewpoint of iron aminopolycarboxylate (I[

The stirring effect is further improved by using a rotating means to improve the stirring effect, and 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. There are four methods: increasing the amount of Wi circulating through the entire intersection. Such means for improving agitation is effective for any of the bleaching solution, bleaching solution, and fixing solution.

The improvement in eight cases is thought to be due to faster supply of bleach and fixer into the emulsion film, resulting in an increase in the desilvering speed. Furthermore, the above-mentioned means for improving agitation is more effective when a bleach accelerator is used, and can increase the accelerating effect by one factor or eliminate the constant M light damage caused by the bleach accelerator.

The automatic developing machine used for the photosensitive material of the present invention was
No. 0-191257, No. 60-191258, No. 60
It is preferable that the photosensitive material conveying means described in Japanese Patent Application No. 19159 be provided. As described in the above-mentioned Japanese Patent Application Laid-Open No. 60-191257, such a conveying means is used to transfer C from the front bath to the rear bath.
It is possible to significantly reduce the amount of processing liquid brought in, and it is highly effective in preventing the deterioration of the processing liquid.Such effects are particularly effective in shortening the processing time in the process and in reducing the amount of processing liquid replenishment required.

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 washing water in the washing process depends on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the purpose, the washing water temperature, the number of washing tanks (number of stages), countercurrent, replenishment method such as I+['a, etc.
It can be set in a wide range depending on various other conditions. Among these, the relationship between the number of flushing tanks and the amount of water in the multistage countercurrent method is described in the Journal of the 5ociety.

You can ask for it.

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
Chlorinated disinfectants such as isothiazolone compounds, thiabendazole, chlorinated sodium isocyanurate, and benzotriazole, etc., written by Hiroshi Horiguchi, "Chemistry of antibacterial and fungicidal agents" (1986), Sankyo Publishing, Hygiene Technology.

The pi (pi) of the washing water in the processing of the photosensitive material of the present invention is from 4 to 9, preferably from 5 to 8. The washing water temperature and the washing time are also controlled by the !g light. Various settings can be made depending on material characteristics, usage, etc., but for -C, 1
20 seconds to 10 minutes at 5-45°C, preferably 25-40°
C selects the range from 30 seconds to 5 minutes. 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. 5g-14834, and No. 60-220345 can be used.

Further, following the water washing process, a further stabilization process may be carried out, such as a stabilizing bath containing a dye stabilizer and a surfactant, which is used as the final bath for color sensitization for photography. Examples of the dye stabilizer include aldehydes such as formalin and grugulaldehyde, N-methylol compounds, hexamethylenetetramine, and aldehyde sulfite adducts.

It is also possible to add various botanical agents and antifungal agents 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 the above-mentioned processing solutions are concentrated by evaporation during processing using an automatic processor or the like, it is preferable to add water to correct the shrinkage.

Microcrystalline dispersions of other dyes were prepared by the method similar to [i, j].

Samples 10/~/30 prepared as described above were tested as follows: 1. Sharpness 2. Color reproducibility 3. Various desilvering tests were conducted.

1. Apply gray exposure through an MTF measurement wedge using an exposure meter with the sharpness color temperature adjusted to ←r00'K.

All the development treatments described below were carried out. The density of the obtained positive image is measured using a minute density meter, and the MTF@f is determined by calculation.
I asked for it. The results are shown in column 1/Ocycle/mm of the red-sensitive layer and the green-sensitive pigeon.

2. Color reproducibility Color temperature gold, g 10θ'KK adjusted I! A sample was subjected to gray flashing with a light intensity of 20 CmS through a continuous wedge in nine totals, and a sample was subjected to lightning flashing with a red filter added at a light intensity of ψ0 cm5. Exposure x' was performed with a green filter added at a light intensity of tA Ocms. A sample amount was subjected to the development treatment shown in the sharpness test, the density was measured, and the sensitivity of the red-sensitive layer and the green-sensitive layer at a density of 0.2 was determined.

The difference between the gray j1 light sensitivity and the red exposure sensitivity of the red-sensitive layer is an indicator of red color reproduction, and the larger the sensitivity difference, the more vivid the red color will be. Similarly, the difference between the gray bulb light sensitivity with no green sensitivity and the green m light sensitivity was used as an indicator of green color reproduction.

The greater the difference in sensitivity, the higher the purity of the color and the more vividly the color appears.

The results are shown in Table 1.

The amount of sea bream remaining in the sample was measured by reducing the amount of sea bream to 1 minute.

(Effect of the invention) As can be seen from the results shown in Table (2).

The present invention provides a silver agenide reversal color sensitive material which has excellent performance in which the sharpness and color reproduction are greatly improved and the desilvering property is not deteriorated.
