Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for forming a color image by developing a silver halide color photographic light-sensitive material. The present invention relates to a novel color image forming method for forming color prints.

(Prior Art) In recent years, higher efficiency and higher productivity have been required for processing color photographic materials. This trend is especially noticeable for color print production.
There is a strong desire to shorten printing processing time due to the demand for quick finishing.

As is well known, the process of finishing a color print consists of exposure and color development. Using highly sensitive photosensitive materials leads to shorter exposure times. On the other hand, in order to shorten the color development processing time, it is essential to realize a system that combines a photosensitive material and a processing solution or processing method that can speed up development.

As a technology to achieve these issues, we have developed a color printer that contains a silver chloride emulsion instead of the silver chloride bromide emulsion with a high silver bromide content that has been widely used in conventional photosensitive materials for color printing (hereinafter referred to as color photographic paper). Methods of processing photographic materials are known. For example, International Patent Publication WO87-04
No. 534 discloses a method for rapidly processing a color photographic material made of a silver chloride emulsion with a color developer substantially free of sulfite ions and benzyl alcohol.

In addition to the above-mentioned patent, JP-A No. 61-40552 discloses a method for reducing the developer solution by using a high-silver chloride color photographic light-sensitive material and adding a replenishing amount to prevent overflow into the developer bath during development. A method for replenishment is described, and furthermore,
3-106655, for the purpose of stabilizing the process,
A method is disclosed in which a high-silver chloride color photographic material is processed with a color developing solution containing a hydroxylamine compound and a chloride ion concentration above a certain level.

In this way, by using a high silver chloride emulsion and devising a developing processing solution, it is possible to develop a film for 3 minutes and 30 seconds in a conventional silver chlorobromide emulsion system (e.g. Fuji Photo Film special color processing CP-20).
The development time has been shortened to 45 seconds (for example, the total processing time for Fuji Photo Film special color processing CP-40FAS is 4 minutes), but the total processing time for other color methods (for example, electrostatic transfer method, thermal transfer method, inkjet method) is shortened. Compared to that, it is still unsatisfactory (hard to say that level).

Therefore, it has been desired to develop a silver halide color photosensitive material for ultra-quick processing that can significantly shorten the total processing time by using a silver halide color development method that can produce high-quality color prints at low cost. .

On the other hand, approaches to rapid processing using methods other than emulsion technology are also being researched. In particular, Japanese Patent Application Laid-Open No. 63-389 describes a technique that can reduce the development time to 180 seconds or less in a silver chlorobromide emulsion system.
No. 37, No. 63-40144, No. 63-146039
No. 61-286855, No. 61-289350, No. 61-286854, etc., propose control of the swelling thickness of a light-sensitive material by a processing solution and the amount of applied gelatin, as well as new types of developing agents.

Furthermore, for color photographic materials that can be processed extremely quickly,
It goes without saying that shortening the total processing time from the start of processing to the end of processing (in a dry state) is important in terms of product value, but in particular, simplifying and speeding up the washing or stabilization process will reduce the development time. The amount of liquid components and bleach-fixing solution components remaining in the photosensitive material is significantly greater than in conventional processing times such as water washing or stabilization processing.

It has been known for a long time that the residual components of the developer and bleach-fixer on the photosensitive material affect the storage stability of prints. Residual color developing agent reacts with unreacted coupler over time, resulting in undesirable staining. Further, if the bleaching component remains, the photosensitive material becomes an oxidizing atmosphere, resulting in yellow stain, especially under high humidity and high temperature. These stains tend to be improved by keeping the pH of the photosensitive material low, but lowering the pH worsens the fading of cyan and yellow under high humidity and high temperature. Japanese Patent Publication No. 58-1483
No. 4, JP 61-20864, JP 60-263
No. 939, No. 61-170742, No. 58-1327
No. 43 and No. 61-151538 disclose techniques for preventing coloring components from being introduced into photosensitive materials or rendering them colorless when washing with water is not sufficient. However, in either case, ultra-quick processing requires much less washing or stabilization time and the amount of washing, so it inevitably introduces a larger amount of developer and bleach-fixer components than conventional washing, making it less effective. Particularly in continuous processing, more coloring components remain in the photosensitive material, and if the resulting print is stored under high temperature and high humidity, it may cause staining in white areas or bleeding in the image, which may reduce the product value. had decreased.

(Problem H to be solved by the invention) As is clear from what has been described above, the purpose of the present invention is to provide high quality, ultra-quick processing, and storage of completed prints under high temperature and high humidity. An object of the present invention is to provide a method for forming color images with excellent quality.

(Means for Solving the Problems) As a result of extensive research, the present invention has found that even in a processing method in which the water washing or stabilization treatment step is as short as 40 seconds or less, and the coloring component tends to remain in the photosensitive material, the above-mentioned general formula ( I), (n)

(Margin below) The invention will be further explained below.

In the present invention, the total processing time (including the drying process) is within 100 seconds, and the water washing process is also shortened to within 40 seconds. It has been known for a long time that if the washing process is carried out very quickly, the remaining color developing agents, bleaching agents, and fixing agents will significantly deteriorate the shelf life of the prints.

Regarding the removal of these residual chemicals from photosensitive materials, Haruhiko Iwano, Takatoshi Ishikawa, and Moto Furusawa et al. presented the paper "The Chemistry Talent Watching" at the 5th International Symposium on Photofinishing Technology (Chicago, 1988). The Way to Ensure Photoprocessing Quality at Minilab J (The Chemistry

ensure Photoprocessing Qu
As reported in MinilabsJ), washing time, washing temperature, and stirring speed are effective for removing developing agents, and washing water volume is effective for removing ferric ethylenediaminetetraacetate, which is frequently used as a bleaching agent. It has been found that this difference (the difference between a means for promoting the removal of the developing agent and a means for promoting the removal of the bleach) is dependent on the magnitude of the interaction with the binder.

Particularly in ultra-quick processing, it has been found that the shelf life (increased staining, image blurring) of prints subjected to continuous processing is extremely deteriorated due to the shortened washing time that accompanies ultra-quick processing.

Furthermore, in the case of ultra-quick processing and low-replenishment water washing, which is the object of the present invention, the washing time is short, making it difficult to sufficiently remove the developing agent, bleaching agent, and fixing agent.
Bleach (usually ferric ethylenediaminetetraacetate (hereinafter abbreviated as BDT^-Pa(III)) is used for low replenishment below g/g/go) has accumulated and contaminated the washing tank. Storing them away will worsen the print's shelf life (staining and bleeding). That is, this BDTA-F
As described above, e (III) is distributed in the film at the same concentration as during water washing and remains in the photosensitive material even after washing and drying, causing staining under high temperature and high humidity conditions. The amount of ferric ethylenediaminetetraacetate to be used is specified in Japanese Patent Publication No. 61-576.
As written in Example No. 23, bleach-fix solution 1
It is extremely large at 60g (approximately 140 mmol) per serving.

Normally, from the bleach-fixing bath to the washing bath, 3

To remove (I[I'), the amount of water washed and the method of washing (
However, given the demands for ultra-high speed and compact machines, it is not possible to achieve a sufficiently satisfactory amount of washing water or a washing method (multistage countercurrent, etc.). Furthermore, residual BDTA-Fe (I[t) in photosensitive materials not only worsens staining but also promotes coalescence and destruction of oil droplets in the emulsion when prints are stored under high temperature and high humidity conditions. death,
This results in undesirable results such as image blurring. This is because gelatin, which is a binder, and oil droplets containing pigments do not interact with each other, and moreover, BDTA-Fe (I
It is thought that this occurs because gelatin cannot protect the oil droplets due to the interaction between [I] and gelatin, but this has not yet been clearly elucidated.

On the other hand, the developing agent, which is another major factor in staining, is that the developing time is relatively short, the amount used is relatively small, it is largely removed in the next bleach-fixing process, and temperature and agitation The system of the present invention is relatively advantageous in that it is possible to reduce the removal rate by changing the removal rate.

Attempting to ensure performance by washing with low replenishment in such ultra-quick processing would result in undesirable aspects of the equipment, such as using a large amount of washing water and increasing the size of the machine.

As disclosed in JP-A No. 63-158545, Japanese Patent Application No. 62-158642, and No. 63-18439, the compound of the present invention chemically bonds with the developing agent remaining after processing to form a chemically inert compound. Since it is characterized by producing a colorless compound, as in the present invention, BDTA-Pe(II[
It was an unexpected result that a system in which the amount of residual chlorine (2) is more effective than that of the developing agent, and that it has an effect on the storage stability (dye bleeding) of prints other than stain. The reason for this effect is also thought to be related to the interaction with gelatin, which is a binder, but it is not clear. Furthermore, when the compound of the present invention was subjected to a stain test in the presence of only εDTA-Fe(III) in the absence of substantially any developing agent, an unexpected effect was also observed, with BDTA-Fe(III) remaining. It was found to reduce the sting. In such a simple, rapid, and low-replenishment water washing system, the compound of the present invention has been found to have a hitherto unanticipated effect on the storage stability of prints.

In the present invention, the "alkali consumption amount" of the photosensitive material is measured and calculated by the following measuring method. A sample of 1 m") is sampled and peeled between the support and the coated layer. A normal support is paper laminated with polyethylene, and it is possible to peel between these layers. Next, the coated layer is peeled off. Crush the layer side finely,
This is dispersed in a certain amount of water (specifically Loom). Next, this liquid is mixed with an alkaline aqueous solution (specifically, 0
．． Titrate with IN potassium hydroxide solution and adjust from pH 6.0 to p
The amount of potassium hydroxide required to reach H10.0 is
Define "alkali consumption" in millimoles.

If the support contains an acid component and cannot be peeled off as described above, evaluation can be made by subtracting the measured value of the support alone.

This alkali consumption rate evaluates the acid component contained in the photosensitive material and its pH buffering ability.
Specifically, it is affected by gelatin, which is a hydrophilic binder, and other organic compounds in the photosensitive material.

In the present invention, if the amount of alkali consumed is large, the high alkalinity during the initial development cannot be maintained, so the initial development is delayed, and it is not possible to shorten the development processing time. It is thought that this may also affect the occurrence of staining during treatment, and when used in combination with the compound of the present invention, unexpected effects were obtained.

In order to reduce "alkali consumption" which is a feature of the present invention, the following method is preferred.

First, hydrophilic colloids having acidic groups in the sensitive material layer are reduced.

Gelatin is most preferably used as the hydrophilic colloid in a color photographic light-sensitive material using a silver halide emulsion as a photosensor. However, gelatin has a pH buffering capacity against the penetration of alkaline solutions due to its functional groups.

Lowering this buffering capacity is important for speeding up the initial development in rapid processing, and a method of reducing the amount of gelatin is preferred.

Second, gelatin reduction alone may deteriorate membrane physical properties, and therefore is used in combination with a wood-philic polymer that does not have acidic functional groups.

As the hydrophilic polymer that can be used in the present invention, those exemplified herein can be used, and polyacrylamide, polydextran, polyvinyl alcohol, and the like are particularly preferably used.

Thirdly, the type of gelatin used as the hydrophilic colloid is changed.

Specifically, by changing the processing method during gelatin production, or by using esterified gelatin or amidated gelatin with fewer acid groups in gelatin, we can change the number of functional groups and change the isoelectric point, thereby reducing alkali consumption. It can be suppressed.

Fourth, the amount of organic compound materials other than gelatin (specifically, couplers, hydroquinone, phenolic compounds, etc.) used is reduced. When such means are used in combination with a hardening agent, it is also possible to form a photosensitive material with a high initial swelling rate.

Fifthly, the amount of alkali consumption can be reduced by adjusting the values of p and a of the organic compound described in the fourth section.

As described above, it is important to suppress the "alkali consumption" of photosensitive materials, which is the solution of the present invention. The alkali consumption is 3.0 mmol/m3 or less, preferably 2.8 mmol/lo', more preferably 2.6 m
mol/m' or less, particularly preferably 1.9 mmol/
m'' or less.

The color photographic light-sensitive material according to the present invention is constructed by coating a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer on a support. be able to.

In general color printing paper, the layers are usually coated on the support in the above order, but the layers 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 silver halide emulsions sensitive to each wavelength range, and dyes that are complementary colors to the light to which they are exposed - yellow for blue, magenta for edges, and cyan for red. By containing a so-called color coupler, subtractive color reproduction can be performed. However, the coloring hue of the photosensitive layer and coupler is
It is also possible to adopt a configuration that does not have the above-mentioned correspondence.

(Hereinafter, blank spaces) As the silver halide emulsion used in the present invention, one consisting of silver chlorobromide or silver chloride that does not substantially contain silver iodide can be preferably used. Here, "substantially free of silver iodide" means that the silver iodide content is 1 mol% or less, preferably 0.2 mol% or less. The halogen composition of the emulsion may be different or the same among the grains, but if an emulsion 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 is different, or
Particles with a structure that has parts with different halogen compositions in a non-layered manner inside or on the particle surface (if on the particle surface, parts with different compositions are joined on the edge, corner, or surface of the particle) are appropriately selected and used. be able to. In order to obtain high sensitivity, it is more advantageous to use one of the latter than particles with a uniform structure, and it is also preferable from the viewpoint of pressure resistance. When the silver halide grains have the above structure, the boundaries between the parts that differ in halogen composition are
The boundaries may be clear, or may be unclear due to the formation of mixed crystals due to compositional differences, or may have continuous structural changes.

The silver chloride content of the high silver chloride emulsion of the present invention is preferably 90 mol% or more, more preferably 95 mol% or more.

It can be located inside the grain, on the edge, corner, or surface of the grain surface, but one preferred example is epitaxial growth on a part of the corner of the grain.

On the other hand, in order to minimize the decrease in sensitivity when the photosensitive material is subjected to pressure, it is also preferable to use particles with a uniform structure in which the distribution of halogen composition within the particles is small.

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

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

is preferably 0.1-2μ.

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

The shape of silver halide grains contained in photographic emulsions is regular (cubic, tetradecahedral, or octahedral).

The metal may be aluminum, tin, silver, magnesium, or an alloy thereof, and the surface may be a surface of a metal plate, metal foil, or thin metal layer obtained by rolling, vapor deposition, plating, or the like.

Among these, it is preferable to obtain the metal by vapor-depositing the metal onto another substrate. It is preferable to provide a water-resistant resin and a thermoplastic resin layer on the metal surface.An antistatic layer is preferably provided on the side opposite to the metal surface of the support used in the present invention. For details of such supports, see, for example, JP-A-61-
No. 210346, No. 63-24247, No. 63-24
It is described in No. 251 and No. 63-24255.

These supports can be appropriately selected depending on the purpose of use.

As a light-reflecting substance, it is best to thoroughly knead a white pigment in the presence of a surfactant, and also coat the surface of the pigment particles with
It is preferable to use one treated with tetravalent T alcohol.

The occupied area ratio (%) of white pigment fine particles per specified unit area is most typically calculated by dividing the observed area into 6-×6- adjacent unit areas, and then calculating It can be determined by measuring the occupied area ratio (%) (R1) of the fine particles. The coefficient of variation of the occupied area ratio (%) is the ratio s of the standard deviation S of R4 to the average value (R) of R4
/R can be obtained. The number (n) of target unit areas is preferably 6 or more. Therefore, the coefficient of variation S/π can be found as follows.

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

(Hereinafter referred to as margins) The color photographic material according to the present invention is preferably subjected to color development, bleach-fixing, and water washing treatment (or stabilization treatment). Bleaching and fixing may be carried out separately instead of in one bath as described above.

The color developer used in the present invention contains a known aromatic primary amine color developing agent.

A preferred example is a p-71 dilene diamine derivative, and representative examples are shown below, but the invention is not limited thereto.

D-IN, N-diethyl-p-phenyl diamine D-22-amino-5-diethylaminotriene D-32-amino-5-(N-ethyl-N-laurylamino)toluene D-44-[N -Ethyl-N-(β-hydroxyethyl)aminocoaniline D-52-methyl-4-[N-ethyl-N-(β-hydroxyethyl)aminocoaniline D-62-methyl-4CN-ethyl-N- (3-hydroxypropyl)aminocoaniline D-74-amino-3-methyl-N-ethyl-N-(β
-(methanesulfonamide)ethyltwoaniline D-8N-(2-amino-5-diethylaminophenylethyl)methanesulfonamide D-9N,N-dimethyl-p-7 22-diamine D-104-amino-3- Methyl-N-ethyl-N-methoxyethylaniline D-114-amino-3-methyl-N-ethyl-N-β
-Ethoxyethylaniline D-124-amino-3-methyl-N-ethyl-N-β
-Butoxyethylaniline Among the above p-fluorinated diamine derivatives, exemplary compounds D-4 and D-6 are particularly preferred.

Further, a developing agent may be mixed and used if necessary. Further, these p-phenylenediamine derivatives may be salts such as sulfates, hydrochlorides, sulfites, and p-toluenesulfonates. The amount of the aromatic primary amine developing agent used is preferably in a concentration of about 0.1 g to about 20 g, more preferably about 0.5 g to about 12 g per developer solution 11.

In practicing the present invention, it is preferred to use a developer solution that is substantially free of benzyl alcohol. Here, "substantially free" means preferably 2i/1 or less,
More preferably, the benzyl alcohol concentration is 0.5 mt'/f or less, and most preferably, it contains no benzyl alcohol at all.

It is more preferable that the developer used in the present invention does not substantially contain sulfite ions. The sulfite ion functions as a preservative for the developing agent, and at the same time has the effect of dissolving silver halide and reacting with the oxidized product of the developing agent to reduce the dye formation efficiency.

Such an effect is presumed to be one of the causes of increased fluctuations in photographic characteristics due to continuous processing. Here, "substantially not containing" preferably means 3. A sulfite ion concentration of OX 10-'morph 1 or less, and most preferably no sulfite ions.

However, in the present invention, a very small amount of sulfite ion used to prevent oxidation in a processing agent kit in which the developing agent is concentrated before being mixed into a solution for use is excluded.

The developer used in the present invention preferably does not substantially contain sulfite ions, and more preferably does not substantially contain hydroxylamine. This is because hydroxylamine functions as a preservative for the developing solution and also has silver developing activity itself, and it is believed that fluctuations in the concentration of hydroxylamine greatly affect photographic properties.

The expression "substantially not containing hydroxylamine" as used herein means preferably a hydroxylamine concentration of 5.0 x 10-' mol/E or less, and most preferably no hydroxylamine at all.

It is more preferable that the developer used in the present invention contains an organic preservative instead of the hydroxylamine or sulfite ion.

The term "organic preservative" as used herein refers to any organic compound that reduces the rate of deterioration of an aromatic primary amine color developing agent when added to a processing solution for a color photographic light-sensitive material. That is, organic compounds that have the function of preventing color developing agents from being oxidized by air, among others, hydroxylamine derivatives (excluding hydroxylamine; the same applies hereinafter), hydroxamic acids, hydrazines, hydrazides, phenols, Especially α-hydroxyketones, α-aminoketones, sugars, monoamines, diamines, polyamines, quaternary ammonium salts, nitroxy radicals, alcohols, oximes, diamide compounds, fused cyclic amines, etc. It is an effective organic preservative.

After desilvering treatment such as fixing or bleach-fixing, washing with water and/or stabilization treatment is generally performed.

The amount of washing water in the washing step can be set over a wide range depending on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the intended use, the washing water temperature, the number of washing tanks (number of stages), and 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 Society.
Talented Motion Picture and Television Engineers (Journal of the 5
Ociety of MotionPicture a
nd Te1evision Engineers) Volume 64, p. 248-253 (May 1955 issue)
It can be obtained using the method described in . Generally, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 5.

According to the multistage countercurrent method, the amount of washing water can be greatly reduced, for example, to 300 m1 per photosensitive material! Although the following is possible and the effects of the present invention are remarkable, problems such as increased residence time of water in the tank cause bacteria to propagate and generated floating matter to adhere to the photosensitive material. As a solution to such problems, the method of reducing calcium and magnesium described in JP-A-62-288838 can be used very effectively. Also, JP-A-57-854

Further, in the washing water, a surfactant as a draining agent and a chelating agent such as EDTA as a water softener can be used.

The above-mentioned water washing step can be followed or the stabilizing solution can be directly treated without going through the water washing step. A compound having an image stabilizing function is added to the stabilizing liquid, such as an aldehyde compound such as formalin, or a film suitable for stabilizing the dye.
Examples include buffers for preparing H and ammonium compounds. Further, in order to prevent the proliferation of bacteria in the liquid and to impart anti-mold properties to the photographic material after processing, the various disinfectants and anti-mold agents described above can be used.

Furthermore, surfactants, optical brighteners, and hardeners can also be added. In the processing of the photosensitive material of the present invention, when stabilization is performed directly without passing through a water washing step,

These organic phosphonic acids and/or organic phosphonates may be used alone or in combination of two or more.

The amount of these organic phosphonic acids and/or organic phosphonates added to the water washing or stabilizing bath can be determined by the amount of ferric ethylenediaminetetraacetate contained in the photosensitive material. 2.9m per bath 11
The amount added is preferably from mol to 290 mff+ol. More preferably, it is 14.6 diagonal o1-146 positive o1. If the amount added is too large, the surface may become sticky, while if it is added too little, the original stain improvement effect will not be achieved.

It is also a preferred embodiment to use magnesium or bismuth compounds.

In addition, it is also a preferable embodiment to use chelating agents such as 1-hydroxyethylidene-1,1-diphosphonic acid and ethylenediaminetemethylenephosphonic acid, and magnesium and bismuth compounds.

A so-called rinsing solution is also used as a washing solution or stabilizing solution used after desilvering treatment.

The preferred pH of the water washing step or stabilization step is 4 to 10, more preferably 5 to 8. The temperature can be set in various ways depending on the use and characteristics of the photosensitive material, but generally it is 30 to 45°C.
, preferably 35 to 42°C. Although the time can be set arbitrarily, a shorter time is preferable from the viewpoint of reducing processing time.

Preferably 10 seconds to 45 seconds, more preferably 10 seconds to 4 seconds
It is 0 seconds. The smaller the amount of replenishment, the lower the running cost.
Preferable from the viewpoint of reducing emissions and ease of handling.

A specific preferable replenishment amount is 0.5 to 50 times, preferably 2 to 15 times, the amount brought in from the previous bath per unit area of the photosensitive material. Or, it is 300 d or less, preferably 150 d or less per photosensitive material. Further, replenishment may be performed continuously or intermittently.

The liquid used in the water washing and/or stabilization step can also be used in the previous step. An example of this is to flow over 70 ml of washing water, which has been reduced by a multi-stage countercurrent system, into a bleach-fixing bath, which is a pre-bath, and replenishing the bleach-fixing bath with a concentrated solution to reduce the amount of waste liquid.

Next, a drying process that can be used in the present invention will be explained.

In order to complete an image using the ultra-quick processing of the present invention, a drying time of 20 to 40 seconds is desired.

As a means for shortening this drying time, it is possible to improve the drying time by reducing the amount of water carried into the film by reducing the amount of a hydrophilic binder such as gelatin. Also, from the perspective of reducing the amount carried in, it is possible to speed up drying by absorbing water with a squeeze roller or cloth immediately after leaving the washing bath. Of course, as an improvement from the dryer, it is possible to speed up drying by increasing the temperature or increasing the drying air. Furthermore, drying can be accelerated by adjusting the angle at which the drying air is irradiated onto the photosensitive material or by removing the exhaust air.

(Margins below) (Examples) The present invention will be specifically described below with reference to Examples, but the present invention is not limited thereto.

After carrying out color development processing on Samples 101 to 109 and IOA, the densities of yellow, magenta and cyan were measured using a densitometer to obtain a so-called characteristic curve.

Furthermore, the processed photosensitive material at the end of continuous processing was heated at 50°C for 8
After aging at 0% RH for 28 days, the increase in blue density over time at the lowest density portion was evaluated as stain.

In addition, the bleeding of the magenta dye of the sample after the aging test was evaluated. This evaluation is the distance (unit: mm) from a thin line (width 5 mm) whose green density was 2.00 before the aging test to the point where the green density becomes 0.05 after the aging test.
It was evaluated as d.

The alkali consumption of samples 101 to 109 was 2.5 mm.

It was 1/m'. Table 1 shows the staining results. Table 2 below shows the dye bleeding results.

From Table 11 and Table 2, it can be seen that the effect of the present invention is large and the storage stability of prints is improved even with a short washing time.

Example 2 Using sample 101 of Example 1, the processing conditions are shown in Table 3 below.
Samples 201 to 211 were prepared in the same manner as in Example 1 except for the following changes.

Table 3 Samples 201 to 211 had sufficiently completed images after 15 seconds of development as in Example 1.

The same table shows the results of sample 10A (comparative example) and sample 101 treated in the same manner as in Example-1.

Table 4 below shows the results of staining.

Table-4 Table 5 shows the results of dye bleeding.

Table 5 Samples 205 to 211 of this example are sample 101 of the present invention.
It can be seen that the addition of the organic phosphonic acid further improves the results. Although sample 203 was improved over sample 101, it also had the drawback of increasing the amount of waste liquid. In addition, sample 1 showed that increasing the water washing temperature had a further improvement effect.
This can be seen from 01.201 and 202.

(Effects of the Invention) According to the present invention, ultra-quick and continuous processing was possible, and high-quality color images were obtained. Furthermore, the obtained color image exhibited excellent storage stability even under high temperature and high humidity conditions. In particular, the amount of replenishment in the water washing process should be adjusted to 1 m of photosensitive material.
Even when the ratio was reduced to less than 150 - per +, an excellent color image was obtained in which an increase in staining and image blurring were prevented.
