Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for processing silver halide color photographic light-sensitive materials. More specifically, the present invention relates to a method for processing silver halide color photographic materials. Silver halide color photographic light-sensitive material made of silver chloride (hereinafter simply referred to as color light-sensitive material)
The present invention relates to a color development processing method that provides stable photographic performance in continuous processing, causes less staining of color sensitive materials after processing, and causes less staining even when images are stored for a long period of time.

(Prior Art) In recent years, in the photographic processing of color photosensitive materials, it has been desired to shorten the processing time as the finishing delivery time and laboratory work are reduced.

Increasing the processing temperature and increasing the amount of replenishment are common methods to shorten the time of each processing step, but many other methods have been proposed, such as strengthening stirring or adding various accelerators. There is.

On the other hand, for the purpose of speeding up color development and/or reducing the amount of replenishment, silver chloride emulsions are included in place of conventionally widely used silver bromide thread emulsions or silver chlorobromide emulsions with a high silver bromide content. Methods of processing color sensitive materials are known. For example, International Publication No. WO87104534 describes a method for rapidly processing a high silver chloride color sensitive material with a color developer substantially free of sulfite ions and benzyl alcohol.

However, it has been found that when the development process is performed using an automatic vapor processor based on the above method, streaky fogging occurs. This seems to be a so-called submerged pressure sensitizing stripe, which occurs when the sensitive material is scratched when it comes into contact with a roller or the like in the developing tank of an automatic processor and is pressure sensitized, resulting in striped fog.

In addition, printer exposure speeds have also been increased,
When a roll of color photosensitive material is moved at high speed during exposure, strong peeling occurs on the contact surface, and scratches occur on the contact area between the photosensitive layer surface of the color photosensitive material and the device when it passes through the printer at high speed, resulting in the above-mentioned problems. It has been found that the same treatment causes problems such as streaky pressure sensitization and fogging due to peeling.

Furthermore, during continuous processing with a low replenishment amount of color development, fluctuations in photographic properties (especially an increase in minimum density (D m1n)) are large;
It was found that the color photosensitive material after processing was significantly contaminated, and that staining occurred when the color image was stored.

This fact shows that even when high silver chloride color photosensitive materials are used, low replenishment amounts are processed, and the color development process time is shortened, variations in photographic properties (particularly D m1n), contamination of post-processed photosensitive materials, and color variations occur. This poses a serious problem in that staining occurs when images are saved, and an immediate solution to these problems is strongly desired.

JP-A-58-95345 and JP-A-58-95345 are methods for reducing fluctuations in photographic properties (especially D m1n) caused by continuous processing in rapid processing methods using high silver chloride color sensitive materials.
It is known to use an organic antifoggant in No.-232342. However, its antifogging effect is insufficient, and D min due to the generation of pressure-sensitizing muscles and continuous processing.
It has been found that the use of a large amount of silver does not prevent the increase in the amount of silver, and that when used in a large amount, the maximum density (Draax) decreases and the amount of silver remaining after processing increases.

In addition, JP-A-61-70552 discloses a method for reducing replenishment of the developer by using a high silver chloride color sensitive material and adding a replenishment amount in an amount that does not overflow into the developing bath during development. A method is described in JP-A-63-106655, in which a color sensitive material whose silver halide emulsion layer has a high silver chloride content is treated with a hydroxylamine compound and chloride at a predetermined concentration or higher for the purpose of stabilizing the processing. A method of developing with a color developing solution containing the above-mentioned color developer is disclosed. However, with these methods, the above-mentioned contamination of the processed light-sensitive material during rapid continuous processing with a low replenishment amount and photographic properties (Dmi
n) fluctuations and the occurrence of stains during long-term storage of images are observed, and the above problems are not solved.

On the other hand, color sensitive materials generally have a structure such as a light-sensitive emulsion layer, an intermediate layer, a protective layer, a back layer, sometimes an antihalation layer, a yellow filter layer, etc. on a support such as various plastic films or paper coated with plastic. Several layers are applied in combination as needed. The binder used in this constituent layer is usually hydrophilic colloid, mainly gelatin. However, the coating film made of gelatin has a high coefficient of friction, and if it comes into contact with other metal surfaces, plastic surfaces, or gelatin film surfaces. Silver halide sensitive materials have the disadvantage of being easily scratched, and silver halide in particular is sensitive to pressure, which causes pressure blur and desensitization, which can be fatal to images. This results in an impact.

For this reason, in photographic materials, a non-photosensitive protective layer is usually provided on the photosensitive silver halide emulsion layer, or a base layer is provided on the other side of the support provided with the photosensitive layer. Measures have been taken to reduce the coefficient of friction by making improvements to this layer. One such means is the use of compounds called slip agents. For example, by dispersing fine powder such as silica, glass, polymer, etc. in this layer, the surface is roughened, the contact area is reduced, and the coefficient of friction is reduced.
No. 0664, JP-A-51-115192, JP-A No. 55-1
There is a method described in No. 26138. In addition, high boiling point organic solvents (plasticizers), higher fatty acid salts and their esters, and polymers are used, for example, in U.S. Patent No. 2,97
No. 6.148, No. 3.121,060, No. 3,933
, No. 516, British Patent No. 1.320,757, No. 1,
321.994, 1,430,997, West German patent no. , there are methods described in these.

Although these methods are effective to some extent in reducing the coefficient of friction of the membrane, they each have their own drawbacks. Photographic materials that have a layer containing dispersed inorganic fine particles or polymers are clearly inferior in terms of preventing scratches, and have even been observed to make the scratches worse. lower,
As a result, it has the disadvantage of deteriorating the sharpness of the image. In addition, when high boiling point organic solvents, esters, and polymers are used as liquid compounds, these compounds migrate from the layer to the surface of the sensitive material when stored under high temperature and high humidity conditions. The sensitivity material may adhere, the stability of fine dispersions may depend on the viscosity of the liquid, the type and concentration of surfactant used during preparation, and the preparation of dispersions with a uniform particle size distribution may occur. It has drawbacks such as being difficult to In addition, when they are solids, their dispersibility depends on temperature, making it difficult to prepare dispersions with solubility and stable and uniform particle size distribution, and furthermore, it is difficult to design equipment and control temperature. It has drawbacks such as requiring a large amount of cost. Furthermore, a surfactant is required for dispersion preparation, and the amount used is limited because the surfactant used dissolves into the processing solution during processing, causing problems such as foaming of the processing solution. There are also disadvantages such as:

Furthermore, in recent years, in the processing of color sensitive materials, particularly color papers, reductions in processing liquid replenishment rates have been promoted from the viewpoint of preventing environmental pollution and economical efficiency.

This low replenishment reduces the amount of processing solution discharged, but on the other hand, waste products of various chemicals used in the processing solution and compounds eluted from the sensitive material accumulate. For example, in color developing solutions, oxides of color developing agents accumulate. Furthermore, if the accumulated amount exceeds a certain concentration, or by the influence of other emitted substances, aggregation occurs and scum is generated. In color development processing in such a low replenishment continuous processing system, if the aforementioned high-boiling organic solvents or esters are used as slip agents, these scums tend to adhere, and accumulated waste products, especially oxides of color developing agents, tend to adhere. It has been found that it has a serious drawback in that it easily incorporates color developing agents and color developing agents themselves, resulting in increased staining after processing and during long-term storage of images.

On the other hand, several methods have been proposed for improving the slipperiness of the surface of a photosensitive material by incorporating organopolysiloxane as a slipping agent into a silver halide photosensitive layer, protective layer or back layer. Some examples of these include, for example, U.S. Pat.

It has been found that the use of these organopolysiloxane compounds described in -L as a slip agent also improves the slip properties.

However, all of these examples of the use of organopolysiloxane compounds are related to film properties, such as fluctuations in photographic properties due to processing, contamination of color sensitive materials after processing, and the problem of staining that occurs during color image storage, and their solutions. There is no disclosure whatsoever. Moreover, there is no disclosure at all about low-replenishment continuous treatment of color vapor.

(Problems to be Solved by the Invention) Therefore, the present invention provides color development using a color sensitive material that has been given slipperiness in order to reduce streaky fog and fog caused by peeling of the adhesive surface. A method for processing color sensitive materials that does not cause contamination of color images obtained when continuous processing is performed, provides stable photographic performance (especially Dmin), and that causes less staining even when color images are stored for a long period of time. It is about providing.

The color developing solution contains at least one organic preservative, and has a bromide ion concentration of 3.0 x 10-5 to 1. OX], 0-3 mol/°C, the silver halide emulsion layer of the silver halide color photographic light-sensitive material is composed of 80 mol% or more of silver chloride, and at least one of the non-photosensitive layers This can be achieved by a method for processing a silver halide color photographic material, which comprises processing a silver halide color photographic material containing at least one compound represented by the following general formula (I).

If the concentration is lower than mol/min, it will not be possible to suppress pressure-sensitized fog or an increase in minimum density (D m1n), and furthermore, fluctuations in photographic properties in continuous processing (especially D m1n) will not be suppressed.
) cannot be prevented, and the amount of silver remaining in the photosensitive material after processing increases, so that the object of the present invention cannot be achieved.

Further, in the present invention, it is preferable that the color developing solution contains chlorine ions of 3.5×10-" to 1.5×10-" mol/min. More preferably 4.0×10-"

Similarly to bromine ions, if the concentration of chlorine ions is too high, it will inhibit development and high D max will not be obtained, but if the concentration is too low, it will not be possible to suppress pressure blur, and the D rnin will increase. There is a large variation in photographic properties (D m1n) due to processing. Although the fluctuation range of chlorine ions is slightly smaller than that of bromine ions, it is preferable that the chlorine ion concentration also be within the above range in order to provide users with higher quality color prints.

Here, in order to control the concentration of bromide ions and chloride ions in the color developing solution to a specified level, they may be added directly to the developing solution, or they may be eluted from the color sensitive material during processing. Good too.

When supplied by being eluted from the color sensitive material during processing, both bromide ions and chloride ions may be supplied from the silver halide emulsion, or may be supplied from an additive other than the silver halide emulsion.

In the present invention, from the viewpoint of processing stability during continuous processing and prevention of pressure blurring, it is preferable that the color developer does not substantially contain sulfite ions, but in order to suppress deterioration of the developer, In order to suppress the effects of atmospheric oxidation, physical measures such as using a floating pig or reducing the opening of the developer tank, and chemical measures such as lowering the developer temperature and adding organic preservatives are used. Means can be used. Among these, the method using an organic preservative is advantageous in terms of simplicity.

The organic preservative according to the present invention refers to any organic compound that reduces the deterioration rate of an aromatic primary amine color developing agent when added to a processing solution for a color photographic light-sensitive material.

Preferably, the color developer is substantially free of benzyl alcohol. Substantially means 2 per lβ of color developer.
．． The content should be 0 ml or less, more preferably not at all. Substantially not containing it causes less variation in photographic properties during continuous processing, especially an increase in staining, and more favorable results can be obtained.

In the present invention, in addition to chlorine ions and bromide ions, any antifoggant can be added as necessary. As antifoggants, alkali metal halides such as potassium iodide and organic antifoggants can be used. Examples of organic antifoggants include benzotriazole, 6-
Nidropenzimidazole, 5-nitroisoindazole, 5-medylbenzotriazole, 5-2I-lobenzotriazole, 5-chlorobenzotriazole, 2
Typical examples include nitrogen-containing heterocyclic compounds such as -deazolyl-benzimidazole, 2-thiazolylmethyl-benzimidazole, indazole, hydroxyazaindolizine, and adenine.

The color developer used in the present invention preferably contains an optical brightener. As an optical brightener, 4.4'-
Diamino-2,2'-disulfo lambda tilbene compounds are preferred. The amount added is 0 to 10g/(2, preferably 0
．． It is 1 to 6 g/β.

Furthermore, various surfactants such as alkylsulfonic acids, arylsulfonic acids, aliphatic carboxylic acids, and aromatic carboxylic acids may be added as necessary.

The processing time of the color developer of the present invention is 10 seconds to 120 seconds,
Preferably, the effect of the C1 invention is significant in 20 seconds to 60 seconds. Further, the effects of the present invention are particularly remarkable at a treatment temperature of 33 to 45°C, preferably 36 to 40°C.

The amount of color developer to be replenished during continuous processing is 20 to 220 ml, preferably 25 ml per bottle of photosensitive material.

160 m1, particularly preferably 30 to 3.10 stories, is preferable in that the effects of the present invention can be effectively exhibited.

In addition, the color developer of the present invention has performance superior to combinations other than those of the present invention in any condition regarding its liquid aperture ratio (air contact area (crr?)/droplet volume (crrQ)); From the viewpoint of the stability of the color developer, the interliquid O ratio is preferably O to O, 1crn-'.In continuous processing, it is practically o, ooic+r+-'-0°05ct
The range of y+-' is preferable, and more preferably 0.00
2<em>-' to 0.03 cm-'P.

- When hydroxylamine is used as a preservative in -fi, even if the aperture ratio of the color developer is reduced,
It is widely known that decomposition occurs due to heat or trace metals. However, in the color developer of the present invention,
These decompositions are extremely small, and the color developer can withstand practical use even when the color developer is stored for a long period of time or used as a replenisher for a long period of time. Therefore, in this case, it is preferable that the liquid aperture ratio is small, and 0-
0.002 cm-' is most preferred.

On the other hand, there are cases where processing is performed with a wide aperture ratio under the condition that a certain amount of processing is processed and then discarded, but even in such a processing method, if the structure of the present invention is followed, excellent performance can be achieved. I can do it.

In the present invention, desilvering treatment is performed after one color development. The desilvering step generally consists of a bleaching step and a fixing step, but it is particularly preferable that they are carried out simultaneously.

The bleach or bleach-fix solutions used in the present invention may contain bromides (e.g., potassium bromide, sodium bromide, ammonium bromide), or chlorides (e.g., potassium chloride, sodium chloride, ammonium chloride), or iodides. (eg, ammonium iodide).

If necessary, one or more inorganic substances having pH buffering ability such as boric acid, borax, sodium metaborate, acetic acid, sodium acetate, sodium carbonate, potassium carbonate, phosphorous acid, phosphoric acid, sodium phosphate, citric acid, sodium citrate, tartaric acid, etc. Acids, organic acids and alkali metal or ammonium salts thereof, or corrosion inhibitors such as ammonium nitrate, guanidine, etc. can be added.

The fixing agent used in the bleach-fixing solution or fixing solution according to the present invention is a known fixing agent, namely sodium thiosulfate,
Thiosulfates such as ammonium thiosulfate; thiocyanates such as sodium thiocyanate and ammonium thiocyanate; thioether compounds such as ethylenebisthioglycolic acid and 3,6-dithia-1,8-octanediol, and water-soluble thioureas. These silver halide solubilizers can be used alone or in combination of two or more. It is also possible to use a special bleach-fix solution made of a combination of a fixing agent and a large amount of a halide such as potassium iodide as described in JP-A-55-155354. In the present invention, preference is given to using thiosulfates, especially ammonium thiosulfates. The amount of fixing agent per 1β is preferably 0.3 to 2 mol, more preferably 0.5 to 1.0 mol.

The pH range of the bleach-fix solution or fixer solution in the present invention is as follows:
3 to 8 are preferred, and 4 to 7 are particularly preferred. p
If H is lower than this, the desilvering property will be improved, but the deterioration of the solution and the leucoization of the cyan dye will be promoted. On the other hand, if the pH is higher than this, desilvering is delayed and staining is more likely to occur.

In order to adjust the pH, hydrochloric acid, sulfuric acid, nitric acid, acetic acid, bicarbonate, ammonia, caustic potash, caustic soda, sodium carbonate, potassium carbonate, etc. can be added as necessary.

Further, the bleach-fix solution may contain various other optical brighteners, antifoaming agents, surfactants, and organic solvents such as polyvinylpyrrolidone and methanol.

The bleach-fix solution and fixer solution used in the present invention contain sulfites (e.g., sodium sulfite, potassium sulfite,
ammonium sulfite, etc.), bisulfites (e.g. ammonium bisulfite, sodium bisulfite, potassium bisulfite, etc.), metabisulfites (e.g. potassium metabisulfite, sodium metabisulfite, ammonium metabisulfite, etc.) ) and other sulfite ion-releasing compounds. These compounds are approximately 0.0 in terms of sulfite ion.
The content is preferably 2 to 0.50 mol/l, more preferably 0.04 to 0.40 mol/l. Particularly preferred is the addition of ammonium sulfite.

Sulfites are commonly added as preservatives, but other preservatives include ascorbic acid, carbonyl bisulfite adducts,
Sulfinic acids, carbonyl compounds, sulfinic acids, etc. may be added.

Furthermore, buffering agents, optical brighteners, chelating agents, antifungal agents, etc. may be added as necessary.

The bleach-fix solution of the present invention has a processing time of 10 seconds to 120 seconds, preferably 20 seconds to 60 seconds. Also, is the replenishment amount 1rr of photosensitive material? 30m1) to 250m[l, preferably 4
It is 0d~150ml. Generally, an increase in staining and poor desilvering tend to occur as the replenishment amount is reduced, but according to the present invention, the replenishment amount of the bleach-fix solution can be reduced without causing such problems. I can do it.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to a water washing and/or stabilization process after fixing or desilvering treatment such as bleach-fixing.

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 (the number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set over a wide range. this house,
The relationship between the number of flushing tanks and the amount of water in the multistage countercurrent method is described in the Journal on the Society on Motion.
Picture and Television Engineers (
Journal of the 5ociety of
Motion Picture and DingelevLs
ion 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. The problem arises. In the processing of the color photosensitive material of the present invention, as a solution to such problems,
The method for reducing calcium and magnesium described in Japanese Patent Application No. 61-131632 can be used very effectively. In addition, chlorine-based disinfectants such as isothiazolone compounds, cyabendazole, chlorinated sodium isocyanurate, and other benzotriazoles described in JP-A No. 57-8542, "Chemistry of Antibacterial and Antifungal Agents" by Hiroshi Horiguchi It is also possible to use the disinfectants described in ``Sterilization, sterilization, and anti-mildew technology of microorganisms'', Hygiene Technology Gold Line, and ``Encyclopedia of Antibacterial and Anti-Mold Agents'', published by the Japan Antibacterial and Antifungal Society.

The pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 9.
and preferably 5 to 8. The washing water temperature and washing time can also be set variously depending on the characteristics of the photosensitive material, its use, etc., but generally it is 20 seconds to 2 minutes at 15 to 45°C, preferably 25 to 45°C.
A range of 30 seconds to 1 minute and 30 seconds at 0°C is selected.

Even in such short-time water washing, according to the present invention, there is no increase in staining and good photographic characteristics can be obtained.

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
No. 3, No. 58-14834, No. 59-184343, No. 60-220345, No. 60-238832,
All of the known methods described in No. 60-239784, No. 60-239749, No. 61-4054, No. 61-118749, etc. can be used. In particular, a stabilizing bath containing 1-hydroxyethylidene-1,1-diphosphonic acid, 5-chloro-2-methyl-4-isothiazolin-3-one, a bismuth compound, an ammonium compound, etc. is preferably used.

Further, in the water washing process, a further stabilizing process may be performed, and an example thereof is a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photosensitive materials for photography.

The processing time of the present invention is defined as the time from when the photosensitive material comes into contact with the color developer until it exits the final bath (generally water washing or stabilization bath).
The effects of the present invention can be significantly exhibited in a rapid treatment process in which the processing time is 30 seconds or less, preferably 3 minutes or less.

The conductive polymer or latex (nonionic, anionic, or cationic diamphoteric) described in No. 32462 is preferably used. Inorganic antistatic agents include ammonium, alkali metal, alkaline earth metal halogen salts, nitrates, etc.
Composite oxides prepared by doping conductive tin oxide, zinc oxide, or these metal oxides with antimony or the like described in No. 2 and the like can be preferably used.

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. Furthermore, an infrared-sensitive silver halide emulsion layer can be used in place of at least one of the above-mentioned emulsion layers. 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 that forms, 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 equal among the grains, but if an emulsion having the same halogen composition 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 differs between the grains, or structures with parts with different halogen compositions in a non-layered manner inside or on the surface of the grain (if they are on the grain surface, parts with different compositions on the edges, corners, or surfaces of the grain) Particles having a structure in which the two are bonded can be appropriately selected and used. In order to obtain high sensitivity, it is more advantageous to use one of the latter than particles with a uniform structure, and it is also preferable from the viewpoint of pressure resistance. When silver halide grains have the above-mentioned structure, even if the boundaries between parts with different halogen compositions are clear boundaries, the boundaries may be unclear due to the formation of mixed crystals due to compositional differences. Alternatively, it may be one that actively has continuous structural changes.

Regarding the halogen composition of these silver chlorobromide emulsions, any silver bromide/silver chloride ratio can be used. Although this ratio can vary widely depending on the purpose, a silver chloride ratio of 2% or more is preferably used.

Further, so-called high silver chloride emulsions having a high silver chloride content are preferably used in light-sensitive materials suitable for rapid processing.

In addition, when the dynamic friction coefficient of the top layer of the surface coated with the first to seventh layers of samples 101 to 103 was measured under the following conditions, it was 0.64 for sample 101 and 0.4 for sample 102.

A 5mmφ steel ball with a load of 0g is brought into contact with the 60c
The resistance (F) when moving at a speed of m/win was measured using a load cell, and the value obtained by dividing the resistance (F) by the load was defined as the dynamic friction coefficient and calculated. The measurement was performed three times and the average was calculated.

A small value indicates low dynamic frictional resistance and good sliding properties.

From a comparison of the coefficients of dynamic friction of samples 101 to 103, samples 102 and 103, which used a slip agent, and sample 1, which did not use a slip agent.
It is also clear that the coefficient of kinetic friction is smaller than that of Comparative Compound No. 01, and that the compound represented by the general formula (I) of the present invention has a smaller coefficient of kinetic friction than the comparative compound.

In the case of sample 102, if an ester compound is coated, mainly the developing agent and its oxidized product used in the processing solution during processing are likely to be incorporated into these ester compounds, resulting in increased fog and processing problems. It is presumed that this results in an increase in STEIN over time.

Example 2 Using sample 103 prepared in Example 1, hydroxylamine sulfate was used as a comparison compound for the organic preservative used in the color developer, and the amount added (a degree) was changed, and some Experiments were carried out by changing the type of organic preservative of the present invention. Using the processing steps and processing solution composition shown below, samples that were separately subjected to imagewise exposure were subjected to continuous processing (running test) until three times the capacity of the color development tank was refilled, and tests were carried out before and after the continuous processing. Processing was performed by applying wedge exposure for sensitometry with the same three-color separation filter as in Example 1, and changes in photographic properties (minimum density (I) + in) and sensitivity (S) due to continuous processing were investigated. , we observed the stability of color developers.

Similarly, the difference (ΔS) between the value)) and the sensitivity after the end of the continuous processing was calculated using the sensitivity before the start of the continuous processing as a reference.

On the other hand, after the continuous processing, a portion of the color developing solution was collected from the tank, and the state of the solution was observed to check for turbidity (occurrence of scum).

These results are summarized in Table 2.

From the results in the table above, it can be seen from the D min and sensitivity that the organic preservative used in the present invention allows stable continuous processing. Further, the amount of the organic preservative of the present invention added to the color developing solution is preferably in the range of 5.0 x 10-'' to 5.0 x IO-' mol/β for photographic properties (Dmin, sensitivity).
Fluctuations in color and liquid state of the color developer. It can be seen that at high concentrations exceeding the above concentration range, no further effects are observed and the color developer is saturated, and at low concentrations, the stability of the color developing solution decreases and the photographic properties vary greatly. In addition, when the hydroxylamine used for comparison was added in a high concentration, the characteristic curve chart obtained by measuring the density of yellow, magenta, and cyan showed a lower sensitivity and softer tone compared to the characteristic curve obtained from a low concentration additive solution. observed to change. On the other hand, such a phenomenon was not observed in the organic preservative (If-11) of the present invention.

Example 3 Various materials used in the color paper sensitive material were changed as shown below, and a compound represented by the general formula (I) of the present invention or a known compound was added to the uppermost protective layer among the non-photosensitive layers. Experiments were conducted on photographic properties (minimum density) obtained by continuous processing of samples to which compounds were added, pressure fog, and staining that occurs during image storage.

A multilayer color photographic paper having the layer structure shown below was prepared on a paper support which was laminated on both sides with polyethylene and whose surface was subjected to corona discharge treatment. The coating solution was prepared as follows.

The coating solutions for the second to seventh layers were also prepared in the same manner as the coating solution for the first layer. The gelatin hardening agent for each layer is 1.2-

Next, as sample 302, the seventh layer (protective layer) was
Using the exemplified compounds disclosed in No. 8-90633, these dispersions were prepared according to the following recipe.

A fine homogeneous dispersion was obtained from the liquid having the above composition using an MG homogenizer (bulb type manufactured by Manton-Gorlin). This was added to the seventh layer, and Exemplified Compound (1)/Exemplified Compound (

Samples were prepared by replacing the mixture (weight ratio) with the compound represented by the general formula (I) of the present invention and/or other compounds as shown in Table 3. At this time, the amount of these compounds applied and the amount of gelatin applied were the same as Sample 302.

These samples were given exposures similar to Example 1 and Example 2.
Using Process No. 31 described in , continuous processing was performed while replenishing the sample separately imagewise exposed up to 3 times the tank capacity, and 3 times before and after the continuous processing.
Samples were processed with sensitometric wedge exposures with color separation filters.

The concentration of each sample obtained by the treatment was measured, and ΔD min was determined in the same manner as in Example 1, and ΔD atain was also evaluated on the other hand.

Further, after the continuous processing was completed, the unexposed sample was processed and the pressure blur was evaluated in the same manner as in Example 1.

These results are summarized in Table 3.

From the results in the above table, it can be seen that the seventh layer (protective layer) contains the general formula (
Samples 306 to 314 using the compound represented by I)
△D min compared to sample 301 with no additives at all.
, ΔD 5tain and pressure force blur. In addition, samples 302 to 3 using compounds other than the compound represented by the general formula (I) of the present invention
It can also be seen that the sample using the compound represented by the general formula (1) of the present invention is superior even when compared with 05.

The difference between △D win and △D 5tain is probably due to differences in the ease with which chemicals in the processing solution composition, such as developing agents and their oxidized products, are taken in and washed out by the seventh layer, the topmost layer. It is estimated that this will be affected.

In addition, when the dynamic friction coefficient of the above samples was measured according to the method described in Example 1, sample 301 was 0.64, sample 3 was 0.64, and sample 3 was 0.64.
02-305 is 0.38-0.42, sample 306-31
4 was 0.28 to 0.35, and since this difference in dynamic friction coefficient approximately corresponds to pressure fog, it is thought that the slipperiness of the emulsion surface probably reduces pressure fog.

Example 4 In this example, the compound represented by the general formula (I) of the present invention was used as a non-photosensitive layer, and the other surface (back surface) of the support was
We investigated the effects when used.

First, the surface of a paper support laminated on both sides with polyethylene and the opposite side (back side) to which the undercoat layer had been applied was subjected to a corona discharge treatment, and then a coating solution having the following formulation was applied.

A liquid having the above composition was applied so that the total amount of solid content applied was 15 g/d, and after drying, a coating liquid having the following formulation was applied onto this layer.

The coating amount is 0.015mg/rrr of compound (I-32)
Adjust the coating so that the hardening agent is 1.
3-bis(vinylsulfonylacetamido)ethane was used.

Furthermore, as another support, the following coating solution was applied to the surface which had been subjected to the corona discharge treatment in the same manner as above.

The above coating solution contains compound (I-32) at a concentration of 0.015 g/
A support was prepared by adjusting the coating so as to have the following properties.

Sample 301.30 of Example 3 was coated with a subbing layer on the opposite side of the support coated with these two types of back layers.
2. Apply the same constituent layers as 306 and 314 and apply 3.
01'302'306'314' and 301''
302″, 306″, and 314″ were manufactured.

These samples were subjected to the same treatment as in Example 3, and the same evaluation was attempted. As a result, the obtained ΔDmin, ΔDst
The results for ain and pressure fog were similar to those shown in Table 3, and it became clear that there was no problem in using the compound represented by the general formula (I) of the present invention in the back layer. It has also been found that the slipperiness is improved by using the compound represented by the general formula (I) of the present invention in the back layer.

Example 5 Regarding the magenta dye-forming coupler of a color sensitive material, which is one of the constituent elements of the present invention, we investigated how the photographic properties of different types of magenta dye-forming couplers vary during continuous processing, from the minimum density, and during image storage. This study investigated the extent to which the generated stains differ. A well-known 3-acylaminopyrazolone coupler was used as a comparative magenta dye-forming coupler, and the coupler of the present invention showed little variation in photographic properties and no staining. It has been found that the color photosensitive material forming couplers meet the processing requirements of the present invention. The details of the implementation will be explained below.

A sample was prepared in exactly the same manner as in Example 1, except that the magenta coupler in the third layer (green-sensitive layer) of Sample 103 prepared in Example 1 was replaced with the coupler shown in Table 4 in an equimolar amount. The prepared sample was made without any changes other than replacing the magenta coupler.

Coupler (a) The prepared sample was treated in accordance with Process Step 8 of Example 1, and evaluations of ΔD win and ΔD 5tain were obtained in the same manner.

The results obtained are shown in Table 4. From the results in the above table, it can be seen that in the case of samples 401 to 410, ΔD min and ΔD 5tain were extremely small, and the results were excellent even when the treatment was performed with a low replenishment amount. It is clear that there are

Example 6 This example examines the variation of the coated silver amount of a silver halide emulsion (silver chlorobromide emulsion) on photographic properties in continuous processing using the minimum density (
Dm1n), as well as pressure blur and the amount of residual silver in the processing solution, as well as the effects on photographic properties (maximum density and sensitivity) of color sensitive materials with different silver chloride contents in the silver halide emulsion. I went to see if it would have an impact.

The details will be explained below.

The silver chlorobromide emulsions used in the first layer (blue-sensitive layer), third layer (green-sensitive layer), and fifth layer (red-sensitive layer) of Example 1, Sample 103 were used as they were, and the amount of coated silver was The amount of coated gelatin was not changed by adjusting the amount of diluted gelatin during sample preparation, and the amount of coated silver was only changed as shown in Table 5 below. was created.

Table 5 (Note) The unit is [g/bo].

The prepared sample was subjected to continuous treatment according to the treatment process and treatment liquid composition described in Example 2, and the ΔD
Evaluations were made regarding min., pressure burr, and residual silver amount. These results are shown in Table 6.

As is clear from the results shown in Table 6, it can be seen that the smaller the total coated silver amount, the better the ΔDmin, pressure fog, and residual silver amount. Also, the total amount of silver coated is 0.75g1r
It can also be seen that d or less is preferable.

Next, we changed the silver chloride content of the silver chloride bromide emulsions used for the first, third, and fifth layers, and used silver chlorobromide emulsions prepared by adjusting the grain size and distribution. A sample similar to sample 103 was produced without any changes.

Table 7 The numerical value indicates the silver chloride content [mol%] of the silver chlorobromide emulsion.

Next, the following processing solution was prepared. The composition is as follows.

Table 8 Procedural Amendment (Voluntary) From the results in the above table, it can be seen that the higher the silver chloride content of the silver halide emulsion, the better the sensitivity and D max results. It is clear that when the silver chloride content is 70 mol %, the sensitivity and D max are particularly low and the film is not suitable for rapid processing. It can be said that a silver chlorobromide emulsion having a halogen composition with a silver chloride content of 80 mol % or more is suitable for rapid processing. (In addition, with pure silver chloride, a slight increase in Dmin was observed, although the sensitivity was certainly high.) March 9, 2017
