Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for processing silver halide color light-sensitive materials.

<Prior Art> Silver halide color photosensitive materials (hereinafter referred to as color photosensitive materials) are processed through steps such as color development, desilvering, water washing, and stabilization after exposure.

Color developer for color development, bleach, bleach-fix, and fixer for desilvering, tap water or ion exchange water for washing,
Stabilizing solutions are used in each stabilization process. The temperature of each processing solution is usually adjusted to 30 to 40 DEG C., and the color photosensitive material is immersed in these processing solutions to be processed.

Among these processing steps, the basic ones are a color development step and a desilvering step.

In the color development step, exposed silver halide is reduced by a color developing agent to yield silver, and the oxidized color developing agent reacts with a color former (coupler) to provide a dye image.

In addition, in the desilvering step that follows this color development step, the silver produced in the color development step is oxidized by the action of a bleaching agent, which is an oxidizing agent, and then dissolved by a fixing agent, which is a complex ion forming agent for silver ions. Only a dye image is formed.

The above desilvering process includes a method in which the bleaching process and the fixing process are performed in the same bath, a method in which the process is performed in separate baths, and a method in which the bleaching process and the bleach-fixing process are performed in separate baths. Moreover, in this case, each bath may be multi-tank.

In addition to the above-mentioned basic steps, various auxiliary steps are performed for the purpose of maintaining the photographic and physical quality of the dye image or improving its shelf life. Such a step is carried out using, for example, a hardening bath, a stopping bath, a stabilizing bath, a washing bath, and the like.

The processes shown above are usually carried out using an automatic processor, and in order to maintain the performance of the processing solution constant, the processing amount of the color photosensitive material is generally reduced during continuous processing using an automatic processor. A “replenishment method” that replenishes replenishment fluid according to the
There is a "batch method" in which part or all of the used processing solution is replaced with new solution when the processing amount of color photosensitive material reaches a predetermined amount.

Among these methods, a replenishment method is usually adopted in many cases.

<Problems to be Solved by the Invention> In recent years, with the spread of small in-store processing service systems called minilabs, there has been a strong demand for faster processing.

In particular, the time required for the desilvering process conventionally occupies most of the processing time required for the entire process, and there is a desire to shorten this desilvering process time.

In order to shorten the time, it is desired to use a bleaching agent with strong oxidizing power. Iron, persulfate, bromate, etc. are known, but environmental conservation,
Each of them has many drawbacks in terms of handling safety, metal corrosion, etc., and cannot be widely used for over-the-counter processing.

For this reason, iron aminopolycarboxylate (III
) Complex salts have been used, but the ferric complex salt of ethylenediaminetetraacetic acid, which is mainly used, has the disadvantage of weak oxidizing power.

Among these, for example, JP-A-62-222252 discloses a bleaching solution having a pH of about 6 and containing a ferric complex salt of 1,3-diaminopropanetetraacetic acid having a high oxidizing power.

JP-A No. 62-24253 also describes a bleaching solution containing a ferric complex salt of 1゜3-diaminopropanetetraacetic acid (for example, pH 5
,0) are disclosed.

This product enables more rapid silver bleaching compared to bleaching solutions containing ferric ethylenediaminetetraacetic acid complex salts, but in particular, if bleaching is performed directly after color development without using an intermediate bath, the bleaching fog will be reduced. A major problem is the occurrence of color fog called .

For this reason, ethylenediaminetetraacetic acid ferric (III) complex salt is currently in widespread use, and although various improvements have been made, such as the use of bleach accelerators in order to shorten the processing time, it is still insufficient. isn't it.

The present invention facilitates treatment with a treatment liquid having bleaching ability,
l115i! It is an object of the present invention to provide a method for processing a silver halide color photographic material, which can shorten the silver processing time and prevent the occurrence of defective color recovery.

Means for Solving the Problems> In order to achieve the above objects, the present invention has the following structure FIi (
1).

(1) After imagewise exposure of the silver halide color photographic light-sensitive material,
In a processing method in which a color development process is performed with a color developer containing an aromatic primary amine color developing agent, and then a process is performed with a processing solution having bleaching ability, the processing solution having bleaching ability has an oxidation-reduction potential of 150III.
1. A method for processing a silver halide color photographic material, which comprises containing an oxidizing agent of V or more at a ratio of 0.17-f nyl/1 or more and a compound represented by the following general formula (I).

General formula (I) crystal (In the above general formula (I), RIRz, R3 and R
4 represents a hydrogen atom, an alkyl group or an alkenyl group, respectively. ) <Function> According to the present invention, when processing with a processing liquid having bleaching ability,
No oxidizing agent with an oxidation-reduction potential of 150 mV or more was added to the treatment solution.
．． Since the treatment is carried out by containing the compound represented by the general formula (I) in an amount of 17 mol/l or more, bleaching is promoted and the occurrence of poor color recovery is prevented. Therefore, rapid processing becomes possible.

Furthermore, British Patent No. 1,138,842 discloses that a five-membered heterocyclic compound containing at least two nitrogen atoms in the ring and having at least one mercapto group is used as an aminopolycarboxylic acid metal complex. A method has been proposed for accelerating bleaching by adding thiosulfate and thiosulfate to a bleach-fix solution or a prebath thereof.

However, this method is applied in bleach-fixing processing, and is not intended for a desilvering step separate from bleaching processing, which is a preferred embodiment of the present invention. In addition, the bleach-fixing process takes a long time of about 5 minutes, and a stop-fixing process is required before this process, and the processing time for this process is about 3 minutes, and including this process, it takes about 8 minutes. Therefore, it cannot cope with the rapid processing of the present invention.

In fact, the present inventor has confirmed that when the compound disclosed in the above specification is applied to the rapid bleaching treatment of the present invention, a sufficient bleaching accelerating effect cannot be obtained.

In addition, JP-A-54-52534 discloses that a 5-membered hetero compound containing two or three nitrogen atoms as a ring component is added to a pre-bath of a bleaching bath containing an aminopolycarboxylic acid metal complex as a bleaching agent. Disclosed is a method of treating a cyclic compound containing a heterocyclic compound having at least one mercapto group in its molecular structure.

This document states that it is meaningful to include the compound in the pre-bath of the bleaching bath, and that if the compound is included in the bleaching bath, a sufficient bleaching accelerating effect cannot be obtained. Further, the processing time required for the bleaching step is about 4 minutes to 6 minutes and 30 seconds, and the rapid processing of the present invention cannot be realized.

<Specific configuration> Hereinafter, a specific configuration of the present invention will be explained in detail.

In the method for processing a silver halide color photographic light-sensitive material (hereinafter also referred to as light-sensitive material) of the present invention, the light-sensitive material after imagewise exposure is color-developed and then processed with a processing solution having bleaching ability.

Processing solutions having this bleaching ability include bleaching solutions and bleach-fixing solutions, and typical desilvering treatment steps including treatment with such processing solutions are as follows.

■ Bleach-fix ■ Bleach - Bleach-fix ■ Bleach → Wash with water ■ Rinse - Bleach-fix ■ Bleach - Bleach-fix ■ Wash with water → Bleach-fix ■ Bleach-fix ■ Fix - Bleach-fix Especially, among the above steps, (1), (2), and (2) are preferable, and for process (1), for example, Japanese Patent Application Laid-Open No. 61-75352
In addition, the tank configuration of processing baths such as bleaching baths and fixing baths applied to the above steps may be one tank or two or more tanks (e.g. 2 to 4 tanks, in which case the countercurrent method is preferred).

Among these, in particular, in the present invention, a process in which desilvering treatment is immediately performed with a processing solution having bleaching ability after color development processing is preferred; in this case, the processing solution having bleaching ability is It is preferable that it is a liquid, and a remarkable effect can be achieved in such a process.

Therefore, it is preferable to perform a bleaching process immediately after the color development process, and such a bleaching process will be described below as a representative example.

The bleaching process in the present invention employs a replenishment method in which bleach replenisher is used for replenishment.

Bleach replenisher is used to maintain the processing performance of bleach solution at a constant level.
This is a liquid used to replenish color photosensitive materials according to the amount of processing, and is usually used in continuous processing using an automatic processor.

The bleaching solution in the present invention contains a compound represented by the following general formula (I).

This compound is used by being contained in at least the bleach replenisher, and since replenishment is started at the same time as the process starts, it is always contained in the bleach replenisher during the process.

General formula (I) 1 In the above general formula (1), R+, R*, R3 and R
4 represents a hydrogen atom, an alkyl group or an alkenyl group, respectively.

The alkyl group may have a substituent and preferably has 1 to 5 carbon atoms, particularly 1 to 2 carbon atoms.
It is preferable that

Among these, unsubstituted ones are preferred, such as methyl and ethyl.

The alkenyl group may have a substituent and preferably has 2 to 5 carbon atoms, particularly 2 to 5 carbon atoms.
It is preferable that it is 3.

Among these, unsubstituted ones are preferred, such as vinyl and allyl.

Furthermore, examples of the substituent when the alkyl group or alkenyl group has a substituent include a hydroxy group, an amino group, a nitro group, and the like.

Among the above, in the present invention, R1-R4 are preferably hydrogen atoms or unsubstituted alkyl groups having 1 to 2 carbon atoms, and when they have an alkyl group, R+ "R
It is preferable that any one of 4 is an alkyl group,
Most preferably, all R4-R4 are hydrogen atoms.

Specific examples of the compound represented by general formula (I) are listed below, but the invention is not limited thereto.

(1) Imidazole (2) 1-methylimidazole (3) 2-methylimidazole (4> 4-methylimidazole (5) 4-hydroxymethylimidazole (6) 1-ethylimidazole (7) l-vinylimidazole (8) 4-aminomethylimidazole (9) 2,4-dimethylimidazole (10) 2,4,5-trimethylimidazole (1])
2-aminoethylimidazole (12) 2-nitroethylimidazole Among the compounds exemplified above,
Particularly preferred are (1), (2), (3), (4), and (6), with (1) being the most preferred.

Note that these compounds have an acid dissociation constant (pKa) of 6 to 10.
, particularly preferably 6.5 to 8.5.

Compounds represented by general formula (I) (imidazole compounds) are commercially available, and can be used as they are in the present invention.

These compounds are preferably contained in the bleach replenisher solution up to the solubility limit of o, ooi mol/j or more, particularly preferably 0.05 to 2 mol/l, most preferably 0.1 to 0.5 mol. It is better to set it to eight.

In the continuous processing using an automatic processor, the bleaching solution reaches an equilibrium state after approximately two rounds of processing, and the concentration of the above compound in the bleaching solution in the equilibrium state is expressed by the following relational expression.

Here, one round refers to the time when the cumulative replenishment amount becomes equal to the tank capacity, and the equilibrium state refers to the state of the solution being approximately the same as when it was further processed.

Concentration in bleach solution (in equilibrium state) x (concentration in replenisher solution)
If the concentration of the above-mentioned compound in the bleaching solution in the tank is calculated in an equilibrium state with the amount brought in from the pre-bath being 60 mj/i'', it will be 0.07 mol/i.

In the present invention, the above-mentioned compound may be contained at least in the bleach replenisher solution, but the starting bleach solution is stored in the processing tank at the start of processing or when the processing solution is replaced with a new solution and the processing is restarted. (Mother liquor) may further contain it.

By including the compound in the mother liquor in this way, the effect of adding the above-mentioned compound can be consistently obtained from the start of the treatment.

In this case, the content of the above compound in the mother liquor, like other compounds in the bleaching solution, is about the same amount to twice that in the mother liquor, or even 1.0 times that in the mother liquor.
It should be about 4 to 2 times, preferably about 1.2 to 1.5 times.

The above compounds may be used alone or in combination, and when used in combination, the total amount may be within the above range.

In the present invention, the effect is particularly great when the above compound is contained in the bleach replenisher and continuous processing is performed.

As described above, by incorporating a small amount of the compound represented by the general formula (I) into the bleaching solution, bleaching is promoted and the occurrence of poor color restoration due to the presence of the brown color intermediate is prevented.

Such effects can only be obtained by using the compound represented by the general formula (I), and it is unexpected that the above effects can be obtained with such a relatively small content. .

Since the compound represented by the general formula (I) has a bleach accelerating effect, it is possible to use conventional bleach accelerators without using the compound represented by the general formula (1). Even if only the agent is used, the above effects cannot be obtained.

For example, a 2-mercaptoimidazole compound that has conventionally been preferably used as a bleach accelerator and has an imidazole nucleus similar to that of the compound represented by the general formula (I) is disclosed in British Patent No. 1°138.842. However, when only such compounds are used, the effects of the present invention cannot be obtained.

In the present invention, the bleaching agent which is an oxidizing agent contained in the bleaching solution has an oxidation-reduction potential of 150 m1/ or more, preferably 1
It is 80oV or more, more preferably 200oV or more.

The redox potential of the bleach in the above is determined by Transactions of the Faraday Society 4 (Tr
answers of the Faraday
Society), Volume 55 (1959), 131
It is defined by the redox potential measured by the method described on pages 2 to 1313.

The redox potential in this case was obtained by the above-mentioned method under the condition of pH 6.0.

The reason why the potential determined at pns,o is used is that the vicinity of pue,o is used as a guideline for the occurrence of bleaching fog.

In other words, the present inventors have actually found that when the color development process is completed and the photosensitive material enters the bleaching solution, p in the film of the photosensitive material is
However, if the pH decreases quickly at this time, the bleach fog will be small; if the pH decreases slowly, or if the pH of the bleaching solution
It has been confirmed that the bleaching blade burr becomes larger when the temperature is high.
Based on these facts, pH 6.0 is set as the standard.

In the present invention, a bleaching agent having an oxidation-reduction potential of 150 oV or more is used because such a bleaching agent can provide sufficient oxidizing power and can perform a rapid bleaching process.

Such bleaching agents include inorganic compounds such as red blood salt, ferric chloride monodichromate, persulfate, and bromate, and some organic compounds such as aminopolycarboxylic acid iron (III) complex salt. can be mentioned.

The amount is preferably 0.17 mol or more per I2, and 0.25 mol or more is preferable from the viewpoint of speeding up the processing and reducing bleaching blade blur and stain. Particularly preferred is 0.30 mol or more. However, since the use of an excessively high concentration solution will actually inhibit the bleaching reaction, the upper limit of the concentration is preferably about 0.7 mol.

Furthermore, not only the bleach-fixing replenisher but also the starting bleach-fixing solution (mother liquor) may further contain a compound represented by the formula (I), the content of which is determined in relation to the replenisher. The same procedure as in the case of bleaching solution may be used.

In addition, the liquid composition of the bleach-fix solution used in the bleach-fixing process described above must contain at least 0.17 mol/j of an oxidizing agent (bleaching agent) with an oxidation-reduction potential of 150 ml/j or more. , is basically the same as the bleach-fix solution described above.

In the present invention, the method of containing the compound represented by the general formula (I) and containing 0.17 mol 72 or more of an oxidizing agent (high potential oxidizing agent) having a redox potential of 150 mV or more is as follows:

In the desilvering treatment steps such as bleaching, bleach-fixing, and fixing of the present invention, it is preferable that stirring be as strong as possible in order to more effectively exhibit the effects of the present invention.

A specific method for strengthening stirring is disclosed in JP-A-62-18346.
No. 0, No. 62-183461, the method of impinging a jet of processing liquid on the emulsion surface of a photosensitive material, and the method of colliding a jet of a processing liquid on the emulsion surface of a photosensitive material, as described in JP-A No. 62-183-1.

Such means for improving agitation is effective for all bleaching solutions, bleach-fixing solutions, and fixing solutions. It is believed that improved stirring speeds up the supply of bleaching agent and fixing agent into the emulsion film, and as a result increases the desilvering rate.

Further, the agitation improving means is more effective when a bleach accelerator is used, and can significantly increase the bleach accelerating effect and eliminate the fixing inhibiting effect caused by the bleach accelerator.

As described in No. 7, such a conveying means can significantly reduce the carrying of the processing liquid from the pre-bath to the post-bath, and is highly effective in preventing deterioration in the performance of the processing liquid. Such effects are particularly effective in shortening the processing time in each step and reducing the amount of processing liquid replenishment.

The effect of the present invention is remarkable when the total processing time (excluding drying time) is short, and specifically, the total processing time is 88%.
This effect is clearly exhibited when the processing time is less than 7 minutes, and the difference from conventional processing methods becomes even more remarkable when the processing time is 7 minutes or less.

The processing method of the present invention can also be used for color reversal processing. The black-and-white developer used at this time is a so-called black-and-white first developer used in the commonly known reversal processing of color photosensitive materials. Various well-known additives that are used in black-and-white developing solutions used in processing solutions for black-and-white silver halide light-sensitive materials can be included in the black-and-white first developing solution for color reversal light-sensitive materials.

It is preferable to use water that has been sterilized using halogen or ultraviolet germicidal lamps.

In each of the above processing steps for color photosensitive materials, when continuous processing is performed using an automatic processor, concentration of the processing solution may occur due to evaporation.

This is particularly noticeable when the processing amount is small or when the opening area of the processing liquid is large. In order to correct such concentration of the processing liquid, it is preferable to replenish an appropriate amount of water or correction liquid.

Further, the amount of waste liquid can be reduced by using a method in which the overflow liquid from the water washing step or the stabilization step flows into a pre-bath having a fixing ability.

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

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

As described in No. 23,045, a two-layer structure consisting of a high-sensitivity emulsion layer and a low-sensitivity emulsion layer can be preferably used.
Usually, it is preferable to arrange the halogen emulsion layers so that the photosensitivity decreases in order toward the support, and a non-photosensitive layer may be provided between each halogen emulsion layer.

As described in No. 3, etc., a low-sensitivity emulsion layer may be provided on the side far from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

As a specific example, from the side farthest from the support, low sensitivity blue sensitive layer (BL) / high sensitivity blue sensitive layer (BH) / high sensitivity green sensitive layer (GH) / low sensitivity green sensitive layer (GL) /high-sensitivity red-sensitive layer (RH)/low-sensitivity red-sensitive layer (RL)/in order,

In addition, as described in Japanese Patent Publication No. 49-15495, the upper layer is a silver halide emulsion layer with the highest sensitivity, the middle layer is a silver halide emulsion layer with lower sensitivity, and the lower layer is a silver halide emulsion layer with higher sensitivity than the middle layer. An example is an arrangement consisting of three layers having different photosensitivity, in which a silver halide emulsion layer with low photosensitivity is disposed, and the photosensitivity gradually decreases toward the support. Even when it is composed of three layers with different photosensitivity,
As described in Japanese Patent Application Laid-Open No. 59-202464,
In the same color-sensitive layer, medium-sensitivity emulsion layer/high-sensitivity emulsion layer/low-sensitivity emulsion layer may be arranged in this order from the side remote from the support.

As mentioned above, various layer structures and arrangements can be selected depending on the purpose of each photosensitive material.

Any of these layer arrangements can be used in the color photosensitive material of the present invention, but in the present invention, the dry film thickness of all the constituent layers of the color photosensitive material excluding the support and the undercoat layer and back layer of the support is 20.0μ or less. It is preferable to achieve the object of the present invention. More preferably 1

These film thickness regulations are determined by the color developing agent incorporated into these layers of the color photosensitive material during and after processing. By influencing. In particular, the increase in magenta color, which is thought to be caused by the green-sensitive color layer, is greater than the increase in color of other cyan and yellow colors.

Note that the lower limit value in the film thickness regulation is desirably reduced from the above regulation to a range that does not significantly impair the performance of the photosensitive material. The lower limit of the total dry film thickness of the constituent layers of the photosensitive material excluding the support and the undercoat layer of the support is 12°0μ, and the lower limit of the total dry film thickness of the constituent layers excluding the support and the undercoat layer of the support is 12°0μ. The lower limit of the total dry film thickness of the constituent layers is 1.0μ
It is.

Further, the film thickness may be reduced in either the photosensitive layer or the non-photosensitive layer.

The film thickness of the multilayer color photosensitive material in the present invention is measured by the following method.

The photosensitive material to be measured is stored at 25° C. and 50% RH for 7 days after its preparation. First, measure the total thickness of this photosensitive material, then remove the coated layer on the support, measure the thickness again, and use the difference to determine the total thickness of the photosensitive material excluding the support. The film thickness shall be . The thickness can be measured using, for example, a film thickness measuring device using a contact type electric conversion element (Anritus Electric Co., Lt.
d.

K-402B 5tand). Note that the coating layer on the support can be removed using an aqueous sodium hypochlorite solution.

Next, using a scanning electron microscope, take a cross-sectional photograph of the photosensitive material (magnification is preferably 3,000 times or more), measure the total thickness on the support and the thickness of each layer, and calculate the previous film thickness. Measured value of total thickness by measuring device (absolute value of actual thickness)
The thickness of each layer can be calculated by comparing the

Swelling rate of the photosensitive material in the present invention [(equilibrium swelling film thickness at 25°C, HzO - dry total film thickness at 25°C, 55% RH/dry total film thickness at 25°C, 55% RH)X100] is 5
0 to 200% is preferable, and 70 to 150% is more preferable.

If the swelling ratio deviates from the above value, the amount of color developing agent remaining will increase, and this will have an adverse effect on photographic performance, image quality such as desilvering properties, and film properties such as film strength.

Furthermore, the swelling rate of the photosensitive material in the present invention is defined as the saturated swelling rate, which is 90% of the maximum swollen film thickness reached when processed in a color developing solution (38°C, 3 minutes 15 seconds).
When the time required to reach a film thickness of 2 is defined as the swelling rate T1/2, it is preferable that T1/2 is 15 seconds or less. More preferably Tl/2 is 9 seconds or less.

1.0j pH 5.8 to 8.0 Using each of the processing solutions after the above-mentioned processing, a sample was subjected to wedge exposure at an exposure dose of 5 CMS using a light source with a color temperature of 4800°.

Such treatment depends on the bleach solution used.

Treatments IA to II (Table 1), respectively.

The samples after treatment were examined for occurrence of defective bleaching (defective desilvering) and defective recoloring.

(1) Amount of residual silver (ag/cm
”) was evaluated by measuring with fluorescent X-ray method.

(2) Poor color restoration After measuring the density of the sample after the above treatment, the bleaching solution (N
2), the sample was treated at 38°C for 6 minutes, washed with water for an additional 3 minutes, dried, and then the concentration was measured, and the increase in concentration due to reprocessing was determined for the part with a cyan concentration of 1.5 before reprocessing and evaluated. .

It is considered that the greater the increase in density, the more defective color restoration occurs.

These results are shown in Table 1.

From Table 1, it can be seen that in treatments ID to 1 to which the treatment method of the present invention is applied, bleaching is promoted and the occurrence of defective color restoration is suppressed.

On the other hand, treatments 1B and IC using compounds having a disulfide group or a compound having a mercapto group, which are usually used as bleach accelerators, have almost the same effect as treatment IA, and have a small bleach accelerating effect. , it can be seen that there is no effect of suppressing the occurrence of defective color recovery.

Example 2 In Example 1, except that the bleaching solution was as follows:
Treated in the same way. Depending on the bleach solution used with these treatments, treatment 2 is ~2S (Table 2).

Thereafter, defective bleaching and defective color restoration were examined in the same manner.

The results are shown in Table 2.

From Table 2, 1,3-PDTA-Fe, which is a high potential oxidizing agent,
It can be seen that in treatments 2L to 2N using a bleaching solution containing 0.17 mol/1 or more of (III) and imidazole, bleaching is accelerated and the occurrence of poor color recovery is prevented.

On the other hand, in treatment 2 using a bleaching solution containing only EDTA-Fe (1) as a bleaching agent, the above effect cannot be obtained even if imidazole is contained, and in this case, imidazole is not contained. Processing using bleach solution 2P
In addition, in treatments 2Q to 2S using a bleaching solution that does not contain imidazole, even if the bleaching agent is a high-potential oxidizing agent, the bleaching is further delayed.
It can be seen that, compared to ~2N, neither the bleaching promotion effect nor the recolor failure prevention effect can be sufficiently obtained.

<Effects of the Invention> According to the present invention, bleaching is promoted and the occurrence of poor color recovery is prevented.

Therefore, rapid processing becomes possible, and its effects are more fully demonstrated in such processing.
