Definitions

  • the present invention relates to a method for processing a silver halide photographic light-sensitive material, particularly relates to a method for processing a silver halide photographic light-sensitive material which is effective to reduce the amount of waste liquid of photographic processing effluent.
  • C-41RA from Eastman Kodak Co., Ltd., which is the processing method most widely used in in-shop laboratories or mini-labo's, involves 4 steps, and the replenishing amounts per roll of 135 size, 24 exp. film are 23 ml for the color developing step, 5 ml for the bleaching step, 33 ml for the fixing step and 40 ml for the stabilizing step, respectively.
  • the replenishing amount for the stabilizing solution is largest in these steps. Therefore, a reduction in the replenishing amount of the stabilizing solution has been demanded.
  • a fixing agent such as thiosulfate, a component of a fixing solution
  • the fixing agent is carried into the stabilizing solution from the previous fixing bath by a processed light-sensitive material on which the fixing agent is adhered.
  • the accumulated fixing agent causes formation of a stain on the back surface of the light-sensitive material.
  • the stain appears on a printed picture from the light-sensitive material and causes a serious defect destroying the commercial value of the print.
  • the renewing ratio of the stabilizing solution is lowered by the reduction of the replenishing amount, which causes an extension of time for oxidation of the stabilizing solution by air.
  • formaldehyde is usually contained in the stabilizing solution for preventing stain formation in a unexposed area of the processed light sensitive material during storage and discoloration of color image by blocking the reactive site of an unreacted magenta coupler remaining in the light-sensitive material.
  • the formaldehyde reacts and forms an adduct with sulfite, which is carried over from the fixing solution accompanied with the thiosulfate to the stabilizing solution.
  • the effect of formaldehyde improving the stability of dye is lost and a serious problem of acceleration of sulfurizaton in the stabilizing solution occurs.
  • JP O.P.I. Japanese Patent Publication Open to Public Inspection
  • Nos. 5-119454/1993, 5-165174/1993 and 5-232656/1993 each describe a technology in which a solid processing composition containing thiosulfate is directly supplied into a solution having a fixing ability.
  • a fixing time of 90 seconds for color negative film is disclosed as an embodiment of the technology.
  • concentration of thiosulfate in a processing solution it is necessary to increase the concentration of thiosulfate in a processing solution to a certain level for attaining such rapidness of processing.
  • thiosulfate concentration is made higher, a problem often occurs when there is insufficient daily cleaning of transferring rollers arranged between the first and the second fixing tank or the fixing tank and the next tank such as a stabilizing tank or a washing tank.
  • a hydrophobic decomposition substance of thiosulfate is formed by drying and air-oxidizing of drops of the processing solution adhered on the rollers by the processed light-sensitive material.
  • the hydrophobic substance is tightly fixed on the surface of the rollers by hydrophilic bonding.
  • the hydrophobic substance tightly adhered on the surfaces of the rollers may cause an irrevocable defect such as scratches on the light-sensitive material.
  • the fixing property is raised with increasing the thiosulfate concentration until a certain value, the fixing property is lowered in reverse when the concentration exceeds the certain value.
  • the thiosulfate concentration for enabling the above-mentioned rapid processing corresponds to the above critical concentration. Accordingly, when the amount of light-sensitive material to be processed per day is small, the thiosulfate concentration in the processing solution is apt to raise by virtue of evaporation of the solution. This raising of the thiosulfate concentration causes a problem that the fixing property of the solution is degraded. Further, crystals of thiosulfate are precipitated and grown in the processing solution when such a concentrated processing solution as described above is left to stand under low temperature conditions.
  • the precipitation of thiosulfate causes blocking of circulation of the processing solution and degrades the property of the processing solution due to lowering the effective amount of thiosulfate in the processing solution.
  • a yellow water-insoluble sulfurous substance is formed in a thiosulfate-containing solid composition for fixer or bleach-fixer during the storage under such high temperature conditions.
  • the insoluble sulfurous substance adheres to a filter installed in the fixing tank or bleach-fixing tank of a processor and causes blocking of the filter.
  • the photographic properties of the processing solution are degraded due to insufficient circulation of the processing solution.
  • the precipitated sulfurous substance adheres on the surface of the processed light-sensitive material and considerably spoils the commercial value of the processed light-sensitive material.
  • the solid composition When the solid composition is in the form of granules or tablets, the formation of the sulfurous substance by decomposition of thiosulfate causes lowering in the combining force between components of the composition around the sulfurous substance in the granule or the tablet. As a result of this, the solid composition is easily powdered by vibration or friction.
  • a solution for processing a silver halide photographic light-sensitive material having a fixing ability such as a fixer or a bleach-fixer contains compound which is capable of forming a water-soluble complex salt by reaction with silver halide.
  • a thiosulfate such as potassium thiosulfate, sodium thiosulfate or ammonium thiosulfate
  • a thiocyanate such as potassium thiocyanate, sodium thiocyanate or ammonium thiocyanate, thiourea or a thioether is usually contained as the fixing agent.
  • thiosulfate, particularly ammonium thiosulfate has been frequently used as it is superior in processing properties, stability and solubility.
  • the solubility of potassium thiosulfate or sodium thiosulfate is lower than that of ammonium thiosulfate. Accordingly, the fixing agent is easily precipitated in a concentrated solution at low temperature when these thiosulfates are used instead of the ammonium salt.
  • the concentration of the solution particularly occurs in a mini-labo when the amount of light-sensitive material to be processed is small. Further, in a system with a small amount of replenishing, it is required to increase the concentration of thiosulfate to compensate for degradation in processing ability and stability of the processing solution. It has been found that the increasing in the thiosulfate concentration causes sulfur to adhere to transferring rollers exposed to air, particularly to rollers for transferring provided at a position between a processing tank and the next processing tank (inter-tank rollers).
  • the first object of the invention is to provide a method for processing a silver halide photographic light-sensitive material in which a stain formed on the back surface of the light-sensitive material is prevented when a replenishing amount of a stabilizing solution provided after a fixing solution is reduced.
  • the second object of the invention is to provide a method for processing a silver halide photographic light-sensitive material in which the storage stability of a stabilizing solution is improved and a processing can be stably performed for a prolonged period.
  • the third object of the invention is to provide a method for processing a silver halide photographic light-sensitive material in which reduction of waste liquid formed in the photographic processing can be realized, and the method fits the requirement of environment protection.
  • the fourth object of the invention is to provide a processing method in which a solid processing composition for a silver halide photographic light-sensitive material does not adhere to transferring rollers and maintains a stable fixing ability when the amount of light-sensitive material processed per day is small.
  • the fifth object of the invention is to provide processing method in which a solid processing composition for a silver halide photographic light-sensitive material maintains a good storage ability under a high temperature condition for a prolonged period.
  • the sixth object of the invention is to provide a processing method of a silver halide photographic light-sensitive material in which the ammonium ion concentration can be lowered without precipitation of fixing agent and adhering of insoluble sulfurous substances on inter-tank transferring rollers.
  • a method for processing a silver halide photographic light-sensitive material comprising the steps of fixing or bleach-fixing a silver halide photographic light-sensitive material with a fixing or bleach-fixing solution comprising a thiosulphate in an amount of from 0.6 to 4 moles per litre and at least one compound represented by formula III in an amount of from 0.02 to 5% by weight of the thiosulphate, and
  • Fig. 1 is a structural drawing showing the position in an auto processing machine of a solid processing composition supplying device.

  • the amount of thiosulfate necessary to complete the fixing or bleach fixing reaction can be reduced by addition of a compound represented by Formula III to a solid processing composition containing thiosulfate.
  • a compound represented by Formula III By the reduction in the amount of thiosulfate, adhesion of the decomposition substance of thiosulfate on the surface of the inter-tank transferring rollers can be prevented and the fixing ability of the processing solution can be stably maintained when the amount of the light-sensitive material to be processed per day is small and the solution is concentrated.
  • the processing solution can maintain a stable fixing ability by the use of the above compound even when the concentration of thiosulfate in the processing solution is varied.
  • the inventors further found that the concentration of thiosulfate salt necessary for completing a fixing reaction can be decreased by adding at least one compound represented by Formula III into a fixing solution, and that the processing ability of a fixing solution can be maintained without raising the thiosulfate ion concentration by optimizing the ratio of the amount of ammonium thiosulfate to the amount of potassium thiosulfate and/or sodium thiosulfate.

Description

    Field of the Invention
  • The present invention relates to a method for processing a silver halide photographic light-sensitive material, particularly relates to a method for processing a silver halide photographic light-sensitive material which is effective to reduce the amount of waste liquid of photographic processing effluent.
  • Background of the Invention
  • Recently, makers of photographic material have made efforts for reducing the amount of waste liquid formed in a photographic processing to a limit relating to a tendency of environment protection.
  • The process known as C-41RA from Eastman Kodak Co., Ltd., which is the processing method most widely used in in-shop laboratories or mini-labo's, involves 4 steps, and the replenishing amounts per roll of 135 size, 24 exp. film are 23 ml for the color developing step, 5 ml for the bleaching step, 33 ml for the fixing step and 40 ml for the stabilizing step, respectively. The replenishing amount for the stabilizing solution is largest in these steps. Therefore, a reduction in the replenishing amount of the stabilizing solution has been demanded.
  • However, when the replenishing amount of the stabilizing solution is simply reduced, a fixing agent such as thiosulfate, a component of a fixing solution, is accumulated in the stabilizing solution. The fixing agent is carried into the stabilizing solution from the previous fixing bath by a processed light-sensitive material on which the fixing agent is adhered. The accumulated fixing agent causes formation of a stain on the back surface of the light-sensitive material. The stain appears on a printed picture from the light-sensitive material and causes a serious defect destroying the commercial value of the print. Further, the renewing ratio of the stabilizing solution is lowered by the reduction of the replenishing amount, which causes an extension of time for oxidation of the stabilizing solution by air. As a result of that, a problem of formation of defects caused by sulfurization is apt to occur. Further, formaldehyde is usually contained in the stabilizing solution for preventing stain formation in a unexposed area of the processed light sensitive material during storage and discoloration of color image by blocking the reactive site of an unreacted magenta coupler remaining in the light-sensitive material. The formaldehyde reacts and forms an adduct with sulfite, which is carried over from the fixing solution accompanied with the thiosulfate to the stabilizing solution. As a result of that, the effect of formaldehyde improving the stability of dye is lost and a serious problem of acceleration of sulfurizaton in the stabilizing solution occurs.
  • Recently, solidifying the processing composition for a silver halide light-sensitive material was tried from the view point of reducing environmental pollution and improving the working load for preparating a processing solution. For instance, Japanese Patent Publication Open to Public Inspection (JP O.P.I.) Nos. 5-119454/1993, 5-165174/1993 and 5-232656/1993 each describe a technology in which a solid processing composition containing thiosulfate is directly supplied into a solution having a fixing ability.
  • Undoubtredly, reducing the use of plastic bottles for bottling a replenisher solution kit and lowering working load at the time of preparation of a replenisher solution can be attained by applying the technology disclosed in the above publications. However, it has been found that the problems mentioned below cannot be solved by the above technology only.
  • In the above-mentioned patent publications, a fixing time of 90 seconds for color negative film is disclosed as an embodiment of the technology. Generally, it is necessary to increase the concentration of thiosulfate in a processing solution to a certain level for attaining such rapidness of processing. In the case in which thiosulfate concentration is made higher, a problem often occurs when there is insufficient daily cleaning of transferring rollers arranged between the first and the second fixing tank or the fixing tank and the next tank such as a stabilizing tank or a washing tank.
  • A hydrophobic decomposition substance of thiosulfate is formed by drying and air-oxidizing of drops of the processing solution adhered on the rollers by the processed light-sensitive material.
  • The hydrophobic substance is tightly fixed on the surface of the rollers by hydrophilic bonding. The hydrophobic substance tightly adhered on the surfaces of the rollers may cause an irrevocable defect such as scratches on the light-sensitive material.
  • Further, it has been found, in the relation between concentration of thiosulfate and fixing property, that although the fixing property is raised with increasing the thiosulfate concentration until a certain value, the fixing property is lowered in reverse when the concentration exceeds the certain value. The thiosulfate concentration for enabling the above-mentioned rapid processing corresponds to the above critical concentration. Accordingly, when the amount of light-sensitive material to be processed per day is small, the thiosulfate concentration in the processing solution is apt to raise by virtue of evaporation of the solution. This raising of the thiosulfate concentration causes a problem that the fixing property of the solution is degraded. Further, crystals of thiosulfate are precipitated and grown in the processing solution when such a concentrated processing solution as described above is left to stand under low temperature conditions.
  • The precipitation of thiosulfate causes blocking of circulation of the processing solution and degrades the property of the processing solution due to lowering the effective amount of thiosulfate in the processing solution.
  • On the other hand, in a case that a solid processing composition is stored for a prolonged period on the deck of a ship when the composition is transported by ship, a yellow water-insoluble sulfurous substance is formed in a thiosulfate-containing solid composition for fixer or bleach-fixer during the storage under such high temperature conditions. The insoluble sulfurous substance adheres to a filter installed in the fixing tank or bleach-fixing tank of a processor and causes blocking of the filter. As a result of that, the photographic properties of the processing solution are degraded due to insufficient circulation of the processing solution. Further, it has been found that the precipitated sulfurous substance adheres on the surface of the processed light-sensitive material and considerably spoils the commercial value of the processed light-sensitive material.
  • When the solid composition is in the form of granules or tablets, the formation of the sulfurous substance by decomposition of thiosulfate causes lowering in the combining force between components of the composition around the sulfurous substance in the granule or the tablet. As a result of this, the solid composition is easily powdered by vibration or friction.
  • A solution for processing a silver halide photographic light-sensitive material having a fixing ability such as a fixer or a bleach-fixer contains compound which is capable of forming a water-soluble complex salt by reaction with silver halide. For example, a thiosulfate such as potassium thiosulfate, sodium thiosulfate or ammonium thiosulfate, a thiocyanate such as potassium thiocyanate, sodium thiocyanate or ammonium thiocyanate, thiourea or a thioether is usually contained as the fixing agent. Among them, thiosulfate, particularly ammonium thiosulfate has been frequently used as it is superior in processing properties, stability and solubility.
  • However, a strong odor of evaporated ammonia is generated when ammonium ions are contained in a processing solution. It has been tried, therefore, to reduce the amount of ammonium salt for improvement of working environment.
  • However, the solubility of potassium thiosulfate or sodium thiosulfate is lower than that of ammonium thiosulfate. Accordingly, the fixing agent is easily precipitated in a concentrated solution at low temperature when these thiosulfates are used instead of the ammonium salt. The concentration of the solution particularly occurs in a mini-labo when the amount of light-sensitive material to be processed is small. Further, in a system with a small amount of replenishing, it is required to increase the concentration of thiosulfate to compensate for degradation in processing ability and stability of the processing solution. It has been found that the increasing in the thiosulfate concentration causes sulfur to adhere to transferring rollers exposed to air, particularly to rollers for transferring provided at a position between a processing tank and the next processing tank (inter-tank rollers).
  • Summary of the Invention
  • This invention has been made on the above-mentioned background. The first object of the invention is to provide a method for processing a silver halide photographic light-sensitive material in which a stain formed on the back surface of the light-sensitive material is prevented when a replenishing amount of a stabilizing solution provided after a fixing solution is reduced.

  • Detailed Description of the Invention
  • The inventors found out that the concentration of thiosulfate salt necessary for completing a fixing or bleach fixing reaction can be reduced by adding at least one compound represented by Formula III into a fixing or bleach fixing solution, and that the replenishing amount of a stabilizing solution can be reduced without formation of a stain on the back surface of a light-sensitive material processed and sulfurization or formation of a water-insoluble sulfurous substance in the stabilizing solution by substantially omitting formaldehyde which is reactive with sulfite carried over from the fixing solution.
  • The amount of thiosulfate necessary to complete the fixing or bleach fixing reaction can be reduced by addition of a compound represented by Formula III to a solid processing composition containing thiosulfate. By the reduction in the amount of thiosulfate, adhesion of the decomposition substance of thiosulfate on the surface of the inter-tank transferring rollers can be prevented and the fixing ability of the processing solution can be stably maintained when the amount of the light-sensitive material to be processed per day is small and the solution is concentrated.
  • The processing solution can maintain a stable fixing ability by the use of the above compound even when the concentration of thiosulfate in the processing solution is varied.
  • The inventors further found that the concentration of thiosulfate salt necessary for completing a fixing reaction can be decreased by adding at least one compound represented by Formula III into a fixing solution, and that the processing ability of a fixing solution can be maintained without raising the thiosulfate ion concentration by optimizing the ratio of the amount of ammonium thiosulfate to the amount of potassium thiosulfate and/or sodium thiosulfate. Thus the present invention has been accomplished.
  • A processing method has been known in which a mercapto heterocyclic compound is added to a processing solution. The method includes, for example, a method in which the compound is added to a fixing solution such as described in Japanese Patent Publication Open for Public Inspection (JP O. P. I. No. 1-261640/1989), a method in which the compound is added to a solution of prebath for a bleaching solution such as described in JP O. P. I. No. 54-52534/1979, and a method in which the compound is added to a bleach-fixing solution such as described in British Patent No. 1,138,842. However, these publications do not describe with respect to any stabilizing solution containing no formaldehyde to be used in the following step, and the technical concept of the invention is not expected from the description therein.
  • The compound represented by Formula III is known as a bleach accelerating agent to be used in a bleaching process in which metallic silver is oxidized (refer JP O.P.I. 61-250646/1986). However, it is surprising fact that the compound has a fixing accelerating effect. The compound accelerates the fixing process and is applied after the bleaching step, and silver ions are dissolved and removed from the light-sensitive material in this process. The effect is newly discovered by the inventors as a result of trial-and-error experiments.
  • The solubility of the solid processing composition can be stably maintained and the precipitation of sulfurous substance formed from thiosulfate can be prevented by the use of a compound represented by Formula III even when the composition is stored under high temperature conditions of from 40 to 50°C for a prolonged period.
  • When the solid processing composition is in the form of a granule or a tablet, powdering of the composition after storage under a high temperature condition can be prevented by adding at least one compound represented by Formula III to the solid processing composition.
  • The present invention is described below.
  • A compound of the Formula III useful in the invention will be described.
  • In Formula III, Q1 represents a group of atoms necessary to form a heterocyclic ring including one condensed with a five- or six-membered unsaturated ring, such as a thiazole ring, a thiadiazole ring, an imidazole ring, a pyrimidine ring, a triazole ring, a pyrazine ring, a triazine ring or an oxodiazole ring; R1 represents a hydrogen atom, an alkali metal atom, a group represented Formula III from which R1 is removed or an alkyl group. Q' is synonymous with Q1.
  • Specific examples of compounds of Formula III are exemplified below. However, the present invention is not to be limited to the following compounds.

  • The sugar means a monosaccharide or a polysaccharide in which plural monosaccharides are glycoside-bonded together.
  • A monosaccharide is a general term for a single polyhydroxy aldehyde or polyhydroxy ketone and a wide range of derivatives thereof such as the reduced derivatives, oxidized derivatives, deoxy derivatives, amino derivatives and thio derivatives thereof. Many saccharides are represented by such a formula as CnH2nOn. Herein, the above-mentioned saccharides including the compounds derived from a saccharide skeleton represented by the formula are defined generically as a monosaccharide. Among the monosaccharides, the preferable ones include, for example, a sugar alcohol in which the aldehyde and ketone groups of sugar are each so reduced as to be primary and secondary alcohol groups, respectively, and the particularly preferable ones are, for example, hexitol having 6 carbon atoms.
  • Polysaccharides include, for example, celluloses, starches and glycogens. The celluloses include, for example, derivatives of a cellulose ether of which the whole or a part of the hydroxyl group is etherified. The starches include, for example, dextrin such as a variety of decomposed products produced in the course between a hydrolysis and a production of malt sugar. The celluloses may also be in a form of an alkali-metal salt from the viewpoint of the solubility. Among the above-mentioned polysaccharides, those preferably applicable include, for example, celluloses and dextrins and, those more preferable include dextrins.

  • Among the above-given exemplified compounds, C-(21) to (64) are preferable and C-(21) to (48) are more preferable.
  • These saccharides may be added in an amount within the range of, preferably from 0.5% (W/W) to 30% (W/W) and, more preferably from 1.0% (W/W) to 20% (W/W) per unit weight of the solid processing composition.
  • Saccharides are widely present in nature and are readily available on the market. A variety of derivatives can also readily be synthesized by carrying out a reduction, oxidation, dehydration reaction or the like.
  • The above mentioned compounds represented by Formula (I), polyvinylpyrrolidones, polyvinyl alcohols and sugars can enhance the effects of the solid processing composition when they are contained in the composition either in the form of a raw material of powder, in a granulated form or in a form granulated together with thiosulfates.
  • The prevention of formation of sulfurous substances and of formation of powder after storage under high temperature conditions in the solid processing composition can be further enhanced by addition of a sulfite or a pyrosulfite. The sulfite and pyrosulfite include ammonium salt, sodium salt and potassium salt thereof, and sodium salt and potassium salt are preferable from the view point of the above-mentioned effects. The form of the solid composition includes powder, granule and tablet. Granules and tablets are preferred and tablets are most preferred.
  • Here, "powder" means a mass of fine crystals. "Granule" means grains having a diameter of from 50 to 5,000 µm, which is preferably prepared by granulating a powder. "Tablet" means one which is prepared by shaping a powder or granules in a required tablet form by compression. As the shaping method of the tablet, it is preferable to tablet by compression after granulating the powder or granules, because a stable processing ability can be maintained by thus prepared tablet.
  • As granulating methods for preparation of a tablet, a known method such as a tumbling granulation method, extrusion granulation method, compression granulation method, crushing granulation method, agitation granulation method, fluid-bed granulation method and spray granulation method can be used. The average size of the granulated particles is preferably from 100 to 2,000 µm, more preferably from 200 to 1,500 µm, from the viewpoint that a nonuniformity or demixing of the composition is avoided at the time of mixing and compression of the granulated particles for tableting. The granulated particles preferably have a particle size distribution in which 50% of the particles each have a particle size falling within the range of ±250 µm. Thus obtained granulated particles may be used as the granulated composition without any treatment. For compressing the granulated particles, known compressing machines, such as an oil hydraulic pressing machine, single tableting machine, rotary tableting machine and briquetting machine, can be used. The tablet may be prepared by tabulating a mixture of the granulated particles prepared by the above granulating method and crystals of a raw material available on the market.
  • Although the solid processing composition prepared by compression can take any shape, a cylindrical shape or tablet shape is preferable from the viewpoint of producibility, handling property and dust formation on the user's side.
  • The replenishing composition for the fixer is preferably one containing a small amount of ammonium thiosulfate for improving the working environment. It is preferable that the ratio of ammonium thiosulfate to the total amount of thiosulfates in the fixing solution is not more than 70 mole %, more preferably not more than 30 mole %. The ratio of the sum of the weight of compounds represented by Formula III to the weight of thiosulfate in the composition is preferabaly within the range of from 0.05% to 5% by weight, more preferably within the range of from 0.2% to 2% by weight.
  • The interval from the time at which the fixing process of a light-sensitive material is completed, to the time at which the light-sensitive material is contacted with the stabilizing solution, is preferably not more than 7 seconds, more preferably not more than 5 seconds, further preferably from 1 to 3 seconds.
  • The number of stabilizing tanks may be one, but may be increased to from 2 to 10. Although the replenishing amount of the stabilizing solution can be reduced by increasing the number of stabilizing tanks, the number of stabilizing tanks is preferably from 2 to 6 from the viewpoint of the miniaturization of automatic processor. The replenisher may be separately supplied at several portions, but it is preferable that the replenishing is carried out by a counter-current method (multi-steps counter-current method) in which the replenisher is supplied to a tank provided at a downstream portion with respect to the flow of the light-sensitive material and the overflow solution from the tank (including a solution flowing through a pipe when the tanks are connected by a pipe provided under the surface of the solution) is poured into a tank provided upstream of the tank. The counter-current method includes a cascade method. It is further preferable that the replenisher is supplied to the last stabilizing tank among two or more stabilizing tanks and the over flow solution is poured into previous tank in sequence.
  • The replenishing amount of the stabilizing solution can be considerably reduced by approximately 900 ml or less per square meter of the light-sensitive material processed only by making use of the compound represented by Formula (1). However, it is made possible to obtain the effects of the invention by using the above-mentioned treatment with a replenishing amount of from 50 to 800 ml per square meter of the light-sensitive material. For sufficiently enhancing the effects of the invention, the replenishing amount of the stabilizing solution is preferably from 100 to 650 ml, more preferably from 150 to 500 ml per square meter of the light-sensitive material.
  • The replenishing amount can be further reduced by introducing a processing solution pumped out from the stabilizing tank to the fixing solution in the fixing treatment process.
  • In the processing method relating the invention, the processes of (1) Color developing → Bleaching → Fixing
    • Stabilizing, (2) Color developing → Bleaching → Fixing
    • 1st Stabilizing → 2nd Stabilizing, and (3) Color developing
