Description

[Detailed description of the invention] Industrial application field> The present invention relates to a silver halide color photographic light-sensitive material and a color image forming method using the same. The present invention relates to a novel color photographic material for printing T-shapes and a color image forming method thereof.

(Prior Art) In recent years, extremely high efficiency and high productivity have been required for the processing of color photographic materials. This tendency is particularly noticeable in the production of color prints, and there is a strong desire to shorten the print processing time due to the demand for quick finishing.

As is well known, the process of finishing a color print consists of recognition and color development processing. 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 address these issues, we have developed a silver chloride emulsion containing gold, instead of the silver chlorobromide emulsion with a high silver bromide content, which has been widely used in conventional photosensitive materials for color printing (hereinafter referred to as color photographic paper). Methods of processing color photographic materials are known. For example, International Patent Publication WOr7-0←!
No. 3← discloses a method in which a color photographic light-sensitive material made of a silver chloride emulsion is rapidly processed entirely with a color developer containing substantially sulfite ions and benzyl alcohol.

Additionally, in addition to the above-mentioned percentages, JP-A-6/-70112 discloses that a high silver chloride color photographic light-sensitive material is used, and during development, a replenisher Itwo is added in an amount that does not cause flow into the developing bath. A method for reducing the complementarity of liquids has been described, and furthermore, in JP-A-63-/Ottj! No. 2, No. 2003, discloses a method of processing a high-silver chloride color photographic material with a color developing solution containing a hydroxylamine compound and a chloride ion molecule at a certain concentration or more for the purpose of stabilizing the processing.

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 using a conventional silver chloride bromide emulsion system (e.g. Fuji Photo Film's Color Processing CP-20).
From ←! Second development (for example, CP-u manufactured by Fuji Photo 7 Ilm ■)
The total processing time for oFAs etc. was reduced to φ minutes), but
Compared to the total processing time of other single-color color systems (for example, electrostatic transfer system, thermal transfer system, and inkjet system), it is still difficult to say that the total processing time is at a satisfactory level.

Therefore, using a silver halide color development method that allows high-quality color prints to be obtained at low cost, the halide color is developed for ultra-quick processing within 20 seconds, greatly shortening the total processing time. The development of g-material was highly desired.

On the other hand, approaches to rapid processing other than emulsion technology are also being researched. Especially in a silver chlorobromide emulsion system, the development time f

In this issue, the swelling of the snails using a processing solution, the control of gelatin density, and the use of lrL developing crude drugs have been proposed.

However, based on these conventional findings, it has not been possible to obtain a satisfactory high-quality color photograph with a color development time of less than 0 seconds.

(Problems to be Solved by the Invention) As is clear from the above description, the purpose of the present invention is to provide a method for forming color images with high quality and rapid processing with a development time of less than λO seconds. It is.

Another purpose of the present invention is to provide a silver halide color photosensitive material that can significantly reduce the total processing time and that can compete with other color recording materials in terms of high image quality and processing time. .

(Means for Solving the Problems) As a result of extensive research, the present inventor has found that the "initial We moisture rate" of photosensitive materials is 30%, which is a completely new concept to conventional knowledge.
The above objectives can be effectively achieved by controlling the above, using a high silver chloride emulsion as the silver halide emulsion, and controlling the total amount of hydrophilic colloid used in the photosensitive material to 2. It has been discovered that this can be achieved more effectively by suppressing the o-r to 0 to 8.0 g/m2, leading to the present invention.

That is, the present invention relates to a color image forming method for the following color photographic light-sensitive materials.

(1) A diffusion-resistant oil-soluble coupler that forms a dye by coupling a photosensitive silver halide emulsion with an oxidized product of an aromatic l-class amine color developing agent on at least one side of the support. An ultra-quick color photographic light-sensitive material having at least two layers containing the above, and in which the light-sensitive layers have different sensitivity wavelength ranges, the material having an initial swelling rate of 3Q% or more. Processable color photographic material.

(2) The photosensitive silver halide emulsion contains chloride
It is an emulsion containing gold in an amount of at least 1 ol %, and furthermore, all the hydrophilic colloids used in the sensitive material are co. o-r. The ultra-rapidly processable color photographic material according to item (1) above, which is characterized in that the color photographic material is Og/m 2 .

(3) The ultra-rapidly processable color photographic material according to claim (2), wherein the hydrophilic colloid is gelatin and acrylic thread polymer.

(4) The total gelatin (solid content) coated on the support is 3
．． ! ~6. ! g/m , and the photographic composition on the support is 1-oxy-3,! - ultra-rapidly processable film according to claim (2), characterized in that the film is hardened with dikuaa-S-triazine salt at an addition amount of 2.3×10 −1y×io mol/g gelatin. Color photographic material.

(5) il! The color photographic light-sensitive material described in claim (1) is subjected to imagewise buffing, . A color image forming method characterized by color development within 20 seconds.

The present invention will be explained in detail below.

First, the initial development behavior will be explained.

Normally, the development of color photographic paper involves: ■ penetration of the developer into the group circle, ■ swelling of the film of the photosensitive material, and ■ diffusion of alkali into the film.
■Diffusion of developing agent, etc. into the reaction system, ■Via the development process of silver halide. After that, there are factors such as the rate of color development of the coupler and the infiltration of the developing agent into the oil, but these are not processes that occur in the very early stages of development.

Conventional salt bicarbonate silver emulsion (development time 3 minutes 30 seconds, Fujisha X7
ilm Color paper processing system CP-CO etc.》
Then, after the above-mentioned processes (1), (2), (2) and 0 have almost reached an equilibrium state, the development reaction of silver halide occurs. This is the beginning of silver chlorobromide development! This process was the rate-limiting process because it had an induction period of . Once speeding up of process (2) is achieved, such as by changing the silver halide emulsion used to be of a high silver chloride type, the process that is no longer process (2) becomes rate-limiting. In particular, when the developing time is less than λO seconds, the effects of (1), (2), and (2) in the above process become very large. The inventor's research results using Fuji Photo Film's 7 Color Paper Super FA and CP←OFAS processing systems show that it takes l! ~20 seconds, in the process of ■, it takes ~6 seconds for the alkali to be supplied to the bottom layer, and in the process of ■, it takes 7~r seconds to supply the alkali to the bottom layer, and the development of the bottom layer is It has been found that it does not occur until about /0 seconds before it starts.

Even if the development time fz is 20 seconds, approximately lθ seconds of that time is not used for the development process time.

Considering this, the process of ■~■ above (especially ■~■
). 20'l)) It can be seen that this is an important factor for the following development. Once the development reaction is sufficiently rapid,
In any case, the supply of developing agent and the pH within the film become rate-determining processes.

When the development time is about 10 seconds, the swelling thickness that has reached an equilibrium value plays a large role as a factor in the swelling thickness.

However, in the present invention, the development time is 20 seconds or less. In this case, the swelling is not affected by the equilibrium thickness, but by the swelling@thickness related to the amount of developer taken in at the initial stage of development in l-coseconds. In this way, the present invention 8A is completely different from the content disclosed as the prior art.

In the present invention, the "initial swelling rate" is calculated using the following measurement method. A few drops of a developer kept at 3!0C (the developer of Example 1) were added onto the photosensitive material produced in the present invention, and o. Dot [f+] on the surface of the photosensitive material at a rate of l times per r seconds, and measure the swelling thickness of the film. The ratio of the swelling ff474L (unit=μm) and the saturated phase swelling thickness one second after dropping the developing solution is calculated, and the value is defined as the initial swelling ratio. This initial swelling "4" is a parameter that determines how much developer can be carried into the abdomen at the initial stage of development, and is a very important parameter that has a very large influence on the rapid development that is the object of the present invention.

The BA of the present invention is mainly aimed at speeding up the development process, but when the present invention is implemented, the exposure speed is increased not only in the development process but also in the bleach-fixing process (possibly due to the increased initial swelling speed). It was found that the herbal medicines remaining in the layer were quickly removed by the bleach-fix solution, contributing to shortening the total processing time. Furthermore, in the washing process, because of the above, the residual active ingredient in the washing liquid is quickly removed, and there is also less residual active ingredient brought into the washing liquid.
It has been found that there are advantages such as the amount discharged into the washing liquid is small, and the number of companies using the washing liquid can be reduced. By carrying out the present invention as described above, it is possible not only to speed up the development process, but also to speed up the bleach-fixing process and the washing process.Furthermore, the amount of washing water to be refilled can be reduced, and the size of the automatic developing machine can be made compact. It was also found that there are other benefits.

In order to increase the initial Fte retention rate, which is a feature of the present invention, the following method is preferable.

/Ic reduces the hydrophilic colloid in the photosensitive material layer. Swelling due to hydrophilic colloids also occurs due to the penetration of water or alkali into the photosensitive layer, so that the photosensitive layer gradually absorbs water from above and swells. Within 1 second of penetrating the developer solution, moisture does not reach the lower part of the photosensitive layer due to the casing, and as a result, the emulsion layer in the lower part is not developed, and rapid processing is not possible. Therefore, it becomes possible to reduce the amount of hydrophilic colloid, cause rapid swelling, and supply alkali and developing agent to the underlying emulsion layer.

Secondly, a highly water-absorbing polymer is added to the photosensitive layer to partially replace the hydrophilic colloid. In this method, alkali and herbal medicine outside the membrane! Rather than just diffusion due to a 1 degree gradient,
It can be rapidly absorbed into the photosensitive layer.

Thirdly, use a hardening agent appropriately. The hardening agent moderately crosslinks the hydrophilic colloid. Since the crosslinked portion does not absorb water, it becomes a free passage for water and can promote diffusion to the lower layer. Something similar to the above also occurs on the surface, and is it possible that a water meeting outside the system is occurring? It is effective in bringing it into the photosensitive layer.

In addition, it is possible to change the initial swelling behavior by adjusting the composition in the photosensitive layer, the composition of the developer, and the processing conditions, but in the present invention, the initial swelling rate f30% required for rapid development can be changed.
■These are important factors to control. In order to achieve the object of the present invention, the initial swelling rate is preferably 4 AO% or more,
The larger this value is, the better the case is.

The color photographic light-sensitive batter of the present invention may be constructed by coating at least one layer of a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion on a support. can. In general color photographic paper, the layers are usually arranged on a support in the above order, but the order may be different from this. A solid, infrared-sensitive silver halide emulsion layer can be used in place of at least one of the emulsion layers described above. These photosensitive emulsions rtsvc

Subtractive color reproduction is performed by containing a silver halide emulsion and a color coupler that is complementary to the light to which it is exposed, i.e., yellow for blue, macenta for green, and cyan for red. be able to. However, the coloring hues of the photosensitive layer and the coupler may be #l relatives that do not have the above correspondence.

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, "not actually containing silver iodide" means that the 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 equalize the properties of each grain. Regarding the halogen composition distribution inside the silver halide emulsion grains, there are grains with a so-called uniform structure in which the composition is the same at every temperature in any part of the silver halide grain, and grains with a so-called uniform structure in which the composition ratio is the same at any part of the silver halide grain. ) and the shell surrounding it (-7-t frame multiple layers) have different halogen compositions/* type structure particles or the same part of the particles or non-layered on the surface ■ halogen composition It is possible to appropriately select and use particles with a structure in which the different parts t-W (if on the octad surface, parts of different compositions are joined on the edges, corners, or faces of the particle).High sensitivity can be achieved. In order to obtain silver halide grains, it is more advantageous to use one of the latter than grains with a uniform structure, and it is also preferable from the viewpoint of pressure resistance. The boundaries between different parts of the halogen composition may be clear boundaries, or may be unclear boundaries due to the formation of mixed crystals due to composition differences, and are generally continuous. It may also have a structural change.

The silver chloride content of these high silver chloride emulsions is preferably 0 mol% or more, and 7! Mol% or more is good for length.

Such a high silver chloride emulsion preferably has a structure in which the localized silver bromide layer is formed in a layered or non-layered manner inside and/or on the surface of the silver halide grains as described above. The localized phase preferably has a silver bromide content of at least 10 moles, more preferably more than 20 moles of silver bromide. And these local layers are
It can be located inside the particle, or on the edge, corner, or surface of the particle surface, but one preferred example is one in which a part of the corner of the particle is elongated in an epitaxial manner.

On the other hand, in order to minimize the decrease in sensitivity when a photosensitive material is subjected to pressure, even in high silver chloride emulsions with a silver chloride content of 90 mol% or more, grains with a uniform structure with a small distribution of halogen groups within the grains are used. It is also preferable to use

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 nearly pure silver chloride, such as 0 mole percent, are also preferably used.

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

Alternatively, a composite form of these can be used. Moreover, it may be made of a mixture of crystals having various crystal forms. In the present invention, among these particles, it is preferable to contain particles having the above-mentioned regular crystal shape in an amount of 50% or more, preferably 70% or more, and more preferably 90% or more.

In addition to these, the average aspect ratio (yen equivalent diameter/

This purpose can be achieved by co-emulsifying 0% by weight with the coupler and adding it to the photosensitive layer. In order to prevent the cyan dye image from deteriorating due to heat and especially light, it is more effective to introduce an ultraviolet absorber into the cyan coloring layer and the layers on both sides adjacent to it.

As ultraviolet absorbers, penzotriazole compounds substituted with Wl by an aryl group (for example, U.S. Pat. No. 3,533
, 794), 4-thiazolidone compounds (e.g., those described in U.S. Patent No. 3. 314. No. 794, same No. 3

) can be used. An ultraviolet-absorbing coupler (for example, an α-naphthol-based cyan dye coupler), an ultraviolet-absorbing polymer, or the like may be used.

These ultraviolet absorbers may be mordanted in specific layers.

Among these, penzotriazole compounds substituted with the aforementioned aryl group are preferred.

In addition to the above-mentioned couplers, it is particularly preferable to use the following compounds. Particularly preferred is the combination with a virazoloazole coupler.

That is, a compound (F) that chemically bonds with the aromatic amine developing agent remaining after the color development process to form a chemically inert and substantially colorless compound and/or a compound that remains after the color development process. For example, a compound (G) that is chemically bonded to an oxidized product of an aromatic amine color developing agent to produce a chemically inert and substantially colorless compound may be used simultaneously or alone. This is preferable in order to prevent the generation of stains and other side effects due to the reaction of the coupler with the color developing agent or its oxidized product remaining in the film during storage.

Preferred compounds (F) have a second-order reaction rate constant kz with p-anisidine (in trioctyl phosphate at 80°C) of 1. 012 /moI ・sec ~
l x10−' j! It is a compound that reacts in the range of /mol·sec.

Incidentally, the second-order reaction rate constant can be measured by the method described in JP-A-63-158545.

When k2 is larger than this range, the compound itself becomes unstable and may react with gelatin or water and decompose. On the other hand, if k is smaller than this range, the reaction with the remaining aromatic amine developing agent will be slow, and as a result, side effects of the remaining aromatic amine developing agent may not be prevented.

A more preferable compound (F) can be represented by the following general formula (FI) or (Fff).

General formula (FI) R1-(^)I, -X General formula (FII) R. -C=Y B In the formula, R, and R2 each represent an aliphatic group, an aromatic group, or a heterocyclic group. n represents 1 or 0.

A represents a group that reacts with the aromatic amine developer to form a chemical bond, and X represents a group that reacts with the aromatic amine developer and leaves. B represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, or a sulfonyl group,
Y represents a group that promotes addition of an aromatic amine developing agent to a compound of the primary formula (FIG). Here R,
and X, Y and R, or B may be bonded to each other to form a cyclic structure.

Among the methods of chemically bonding with the residual aromatic amine developing agent, the typical ones are substitution reaction and addition reaction.

As the support used in the present invention, transparent films such as cellulose nitrate film and polyethylene terephthalate, which are usually used in photographic materials, and reflective supports can be used. For the purposes of the present invention, the use of a reflective support is more preferred (CH2=CHSO2.
CH2 CONHCH2 Na2 A hardening aid may be used when hardening a hydrophilic colloid using these hardening agents. Examples of hardening aids include aromatic hydrocarbons having hydroxyl groups, such as hydrogen bond breakers such as thiourea and urea, and hydroquinone.

Furthermore, the "reflective support" used in the present invention is one that enhances the reflectivity and sharpens the dye image formed in the silver halide emulsion layer. This type of reflective support includes a support coated with a hydrophobic resin containing dispersed light reflective substances such as titanium oxide, zinc oxide, calcium carbonate, calcium sulfate, etc. This includes those using the hydrophobic resin contained therein as a support. For example, baryta paper, polyethylene-coated paper, polypropylene laminated paper, transparent supports with a reflective layer or a reflective material, such as glass plates, polyethylene terephthalate, cellulose triacetate, or nitric acid cell CI - Polyester films such as -X, polyamide films, polycarbonate films,
Examples include polystyrene film and vinyl chloride resin.

As other reflective supports, supports having a specular reflective or second type diffuse reflective metal surface can be used. The metal surface has a spectral reflectance of 0.5 in the visible wavelength range.
The above is preferable, and the metal surface can be roughened or gold-plated.
It is preferable to use j4 powder to make it diffusely reflective. The metal may be aluminum, tin, silver, magnesium, or an alloy thereof, and the surface may be a metal plate obtained by rolling, vapor deposition, plating, etc., gold RfI3, or a thin metal layer.

Among these, it is preferable to obtain the metal by vapor-depositing the metal onto another substrate. Preferably, a layer of water-resistant resin, particularly thermoplastic resin, is provided on the metal surface. It is preferable to provide an antistatic layer on the side of the support of the present invention opposite to the side having the metal surface. For details of such a support, see, for example, JP-A-61-210
No. 346, No. 63-24247, No. 63-24251
No. 63-24255, etc.

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 a tetrahydric alcohol.

The occupied area ratio (%) of white pigment fine particles per defined unit area is calculated by dividing the observed area into adjacent unit areas of 611 x 611, and dividing the area of fine particles projected onto that unit area. It can be determined by measuring the occupied area ratio (%) (Rz). The coefficient of variation of the occupied area ratio (%) can be determined by the ratio s/H of the standard deviation S of Ri to the average value (R) of R+. The number (n) of target unit areas is preferably 6 or more. Therefore, the coefficient of variation S/page can be obtained 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."

The color photographic material of 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-7 enedylene diamine derivative, and representative examples are shown below, but the invention is not limited thereto.

D-IN,N--9-ethyl p-phenylenediamine D-2 2-amino-5-diethylaminotriene D-3 2-amino-5-(N-ethyl-N-laurylamino)toluene D-4 4-CN-ethyl N-(β-hydroxyethyl>amino]aniline D-5 2-Methyl-4-[N-ethyl-N-(β-hydroxyethyl)amino]aniline?-6 4-A■No 3-methyl-N-ethyl-N -C

-β-Butoxyethylaniline Among the above p-7 phenylenediamine derivatives, 4-amino-3-methyl-N-ethyl-N-[β-(methanesulfonamido)ethyl]-aniline (exemplified compound D-6) is particularly preferred.

Further, salts of these p-phenylenediamine derivatives such as sulfates, hydrochlorides, sulfites, and p-luenesulfonates may be used. The amount of the aromatic primary amine developing agent used is 1i! Preferably about 0.1 g to about 20
g1, more preferably a concentration of about 0.5 g to about 10 g.

In practicing the present invention, it is preferred to use a developer solution that is substantially free of benzyl alcohol. Here, "substantially not containing" means a benzyl alcohol concentration of preferably 2 ml/1 or less, more preferably 0.W/f or less, and most preferably 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. The sulfite ion concentration is less than or equal to OX 10-' mol/i, and most preferably no sulfite ions are contained.

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.

Here, "not containing substantially hydroxylamine" preferably means 5. A hydroxylamine concentration of less than O x 10-'' mole/l, 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.

III) organic complex salts (e.g. ethylenediaminetetraacetic acid,
Complex salts with aminobocarboxylic acids such as diethylenetriaminepentaacetic acid, aminopolyphosphonic acid, phosphonocarboxylic acid, and organic phosphonic acids) or organic acids such as citric acid, tartaric acid, and malic acid; persulfates; hydrogen peroxide, etc. preferable.

Among these, organic complex salts of iron (III) are particularly preferred from the viewpoint of rapid processing and prevention of environmental pollution. Aminoborigarboxylic acids useful for forming organic complex salts of iron (I[[),
Aminobolyphosphonic acids, organic phosphonic acids, or salts thereof include ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, 1,3-diaminopropanetetraacetic acid, propylenediaminetetraacetic acid, nitrilotriacetic acid,
Cyclohexanediaminetetraacetic acid, methyliminodiacetic acid,
Examples include iminodiacetic acid, glycol ether diamine tetraacetic acid, and the like. These compounds may be sodium, potassium, thium or ammonium salts. Among these compounds, iron(III) complex salts of ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, 1,3-diaminopropanetetraacetic acid, and methyliminodiacetic acid are preferred because of their high bleaching power.

These ferric ion complex salts may be used in the form of complex salts, or ferric salts such as ferric sulfate, ferric chloride,
Ferric ion complex salts are formed in a solution using ferric nitrate, ferric ammonium sulfate, ferric phosphate, etc., and a chelating agent such as aminobolycarboxylic acid, aminobolyphosphonic acid, phosphonocarboxylic acid, etc. You may let them. Further, the chelating agent may be used in excess of the amount required to form the ferric ion complex. Among the iron complexes, aminobolycarboxylic acid iron complexes are preferred, and the amount added is 0.01 to 1.0 mol/l, preferably 0.05 to 0.50 mol/l.

Various compounds can be used as bleach accelerators in the bleach solution, bleach-fix solution and/or their pre-bath. For example, U.S. Patent No. 3. 893,858, German Patent No. 1. No. 290, 812 specification, Japanese Patent Application Laid-open No. 1973
3-95630, Research Disclosure No. 17129 (July 1978 issue), compounds having a mercapto group or disulf7ide bond, and JP-B No. 45-8506, JP-A No. 52-20832, No. 5
No. 3-32735, U.S. Pat. No. 3,706. Thiourea compounds described in No. 561, etc., or halides such as iodine and bromide ions are preferred because they have excellent bleaching power.

In addition, the bleaching solution or bleach-fixing solution that can be applied to the present invention contains bromides (for example, potassium bromide, sodium bromide,
Rehalogenating agents such as ammonium bromide) or chlorides (eg, potassium chloride, sodium chloride, ammonium chloride) or iodides (eg, ammonium iodide) can be included. If necessary, one or more inorganic acids having a pl+ buffering capacity such as borax, sodium metaborate, acetic acid, sodium acetate, sodium carbonate, potassium carbonate, phosphorous acid, phosphoric acid, sodium phosphate, citric acid, sodium citrate, tartaric acid, etc. Organic acids and their alkali metal or ammonium salts or corrosion inhibitors such as ammonium nitrate and guanidine can be added.

The fixing agent used in the bleach-fixing solution or fixing solution is a known fixing agent, namely thiosulfates such as sodium thiosulfate and ammonium thiosulfate; thiocyanates such as sodium thiocyanate and ammonium thiocyanate; ethylene bisthioglycolic acid. , 3,6-dithia], 8-octanediol, and water-soluble silver halide solubilizers such as thioureas. One type or a mixture of 2 m or more of these can be used.

Further, a special bleach-fixing solution consisting of a combination of a fixing agent described in JP-A-55-155354 and a large amount of a halide such as potassium iodide may also be used. In the present invention, the use of thiosulfates, particularly ammonium thiosulfates, is preferred. The amount of fixing agent per 11 is preferably 0.3 to 2 moles, more preferably 0.5 to 2 moles.
The range is 1.0 mol. pH of bleach-fix solution or fix solution
The range is preferably 3 to 10, and particularly preferably 5 to 9.

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

Bleach-fix solutions and fixing solutions contain sulfites (e.g., sodium sulfite, potassium sulfite, ammonium sulfite, etc.) and bisulfites (e.g., ammonium bisulfite, sodium bisulfite, potassium bisulfite, etc.) as preservatives.
, metabisulfite (eg, potassium metabisulfite, sodium metabisulfite, ammonium metabisulfite, etc.).

These compounds have approximately 0.0% in terms of sulfite ion. 02
The content is preferably from 0.05 mol/l, more preferably from 0.04 to 0.40 mol/l.

Sulfites are commonly added as preservatives, but other preservatives include ascorbic acid, carbonyl bisulfite adducts,
Alternatively, a carbonyl compound or the like may be added.

Even more! Buffering agents, optical brighteners, chelating agents, antifoaming agents, antifungal agents, etc. may be added as necessary.・After desilvering treatment such as fixing or bleach-fixing, washing with water and/or stabilization treatment is generally carried out.

The amount of water used in the washing process varies widely depending on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the purpose, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set. 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 of Motion Picture and Television Engineers (Jour
nalor the Soc+ety of Moti
on Picture and Telavi-sio
n Bnginears) Volume 64, p. 248 = 2
53 (May 1955 issue).

Generally, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 4.

According to the multi-throw countercurrent method, the amount of washing water can be greatly reduced, for example, to 0.51 to 11 or less per 1 m' of photosensitive material, and the effect of the present invention is remarkable. The increase in residence time causes problems such as bacteria propagation and the resulting floating matter adhering to the photosensitive material. As a solution to this problem, the method of reducing calcium and magnesium described in JP-A No. 62-288838,
It can be used very effectively. Also, JP-A-57-
Isothiazolone compounds and thiabendazoles described in No. 8542, chlorine-based disinfectants such as chlorinated sodium isocyanurate described in No. 61-120145, JP-A-61
- Penzotriazole, copper ion, etc. described in No. 267761, Hiroshi Horiguchi, "Chemistry of Antibacterial and Antibiotics J" (1986), Sankyo Publishing, edited by Sankyo Gijutsukai, "Sterilization, sterilization, and antimicrobial technology of microorganisms" (1982) It is also possible to use the disinfectants described in "Bacterial and Antifungal Code J (1986)" edited by the Society of Industrial Engineers and the Japan Society of Antibacterial and Antifungal.

Further, in the washing water, a surfactant as a draining agent and a chelating agent typified by 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 represented by formalin, or Mp suitable for dye stabilization.
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,
No. 8543, No. 58-14834, No. 60-22
All known methods described in No. 0345 and the like can be used.

In addition, it is also a preferred 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 15 to 45°C.
Preferably it is 20-40°C. Although the time can be set arbitrarily, a shorter time is preferable from the viewpoint of reducing processing time. Preferably 15 seconds to 1 minute 45 seconds, more preferably 30 seconds to 1 minute
It is minute 30 seconds. The smaller the amount of replenishment, the better from the viewpoints of running costs, reduced emissions, ease of handling, and the like.

A specific preferable replenishment amount is 0.5 to 50 times, preferably 3 to 40 times, the amount brought in from the previous bath per unit area of the photosensitive material. Or it is 1 liter or less, preferably 500 l or less, per 1 m' of 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 reduce the amount of waste liquid by using a multi-stage counter-current system to allow the overflow of the wash water to flow into the bleach-fix bath, which is a pre-bath, and to replenish the bleach-fix bath with concentrated liquid.

Although the present invention provides a development time of substantially 2θ seconds or less for color image formats, it is desirable that the transition time (airborne movement) from each liquid to the next liquid be short. It is preferable that the transition time from the developing solution to the bleach-fixing solution and from the whitening-fixing solution to the washing solution is less than the time in each solution, and more preferably less than the time in each solution. It's below.

In addition, the smaller the amount of liquid t carried over from each liquid to the next, the better the stability of the treatment liquid, and it is preferably less than OCC/m 2 . More preferably, it is 3t)ca/m 2 or less.

The total processing time applied to the present invention from the start of development to the end of the drying process is preferably within 1 minute and aO seconds! It is more preferable that the time is less than 1 minute 30 seconds, and it is the most preferable one.
Within minutes.
