[0167] In this disclosure, it is preferable to use organic solvents with low metal content. For example, a metal content of 10 ppb (parts per billion) or less in the organic solvent is preferred. If necessary, organic solvents at the ppt (parts per trillion) level can be used, such as those supplied by Toyo Gosei Co., Ltd. (Chemical Industry Daily, November 13, 2015).

[0168] Methods for removing impurities such as metals from organic solvents include, for example, distillation (molecular distillation or membrane distillation) or filtration using a filter. For the filter used in the filtration, a pore size of 10 μm or less is preferred, 5 μm or less is more preferred, and 3 μm or less is even more preferred. The filter material is preferably polytetrafluoroethylene, polyethylene, or nylon.

Examples of environmentally controlled substances include benzene; alkylbenzenes such as toluene and xylene; and halogenated benzenes such as chlorobenzene. These are registered as environmentally controlled substances under REACH (Registration Evaluation Authorization and Restriction of CHemicals), PRTR (Pollutant Release and Transfer Register), and VOC (Volatile Organic Compounds) regulations, and their usage and processing methods are strictly regulated. These compounds are sometimes used as solvents in the manufacture of other components used in the coloring composition, and sometimes they are mixed into the coloring composition as residual solvents. From the perspective of human safety and environmental considerations, it is preferable to minimize the amount of these substances. One method for reducing regulated substances is to heat and depressurize the system to a temperature above the boiling point of the regulated substance, and then distill it off from the system to reduce its concentration. Furthermore, in cases where only small amounts of regulated substances are distilled off, azeotropic distillation with a solvent having the same boiling point as the original solvent is useful to improve efficiency. Additionally, in cases involving compounds with free radical polymerization potential, depressurized distillation can be performed after adding a polymerization inhibitor to suppress free radical polymerization reactions during depressurized distillation, which could lead to intermolecular cross-linking. These distillation removal methods can be performed at any stage, including the raw material stage, the product stage (e.g., polymerized resin solutions and multifunctional monomer solutions), or the stage of preparing a colored composition by mixing these compounds.

For example, by using compounds that can replace perfluoroalkyl sulfonic acids and their salts, and compounds that can replace perfluoroalkyl carboxylic acids and their salts, it is also possible to select coloring compositions that substantially do not contain perfluoroalkyl sulfonic acids and their salts, and perfluoroalkyl carboxylic acids and their salts. Examples of compounds that can replace controlled compounds include those removed from controlled substances by differences in the number of carbon atoms in the perfluoroalkyl group. However, the foregoing does not preclude the use of perfluoroalkyl sulfonic acids and their salts, and perfluoroalkyl carboxylic acids and their salts. The coloring compositions disclosed herein may also contain perfluoroalkyl sulfonic acids and their salts, and perfluoroalkyl carboxylic acids and their salts, to the maximum permissible extent.

[0217] The moisture content of the dyeing composition disclosed herein is preferably below 3% by mass, more preferably between 0.01% by mass and 1.5% by mass, and further preferably between 0.1% by mass and 1.0% by mass. The moisture content can be measured by the Karl Fischer method.

As a method for measuring viscosity, for example, a cone-plate type viscometer can be used to measure it at a temperature of 25°C. Regarding the coloring composition disclosed herein, from the viewpoints of environmental compliance, suppression of impurity generation, and suppression of equipment contamination, it is preferable that the chloride ion content in the coloring composition is below 10,000 ppm, and even more preferable that it is below 1,000 ppm. To keep the chloride ion content in the coloring composition within the aforementioned range, methods such as using raw materials with low chloride ion content, removing chloride ions by water washing, ion exchange resins, or filtration can be employed. Known methods can be used to measure chloride ions, such as ion chromatography and combustion ion chromatography.

[0219] <Containment Container> There are no particular restrictions on the container used to contain the coloring composition, and known containers can be used. However, for the purpose of preventing impurities from contaminating the raw materials or coloring composition, multi-layered bottles with an inner wall composed of six layers of six different resins, or bottles with a seven-layer structure of the six resins, are preferred. For example, the container described in Japanese Patent Application Publication No. 2015-123351 can be cited as such a container. Furthermore, for the purposes of preventing metal leaching from the inner wall of the container, improving the storage stability of the coloring composition, or inhibiting component deterioration, it is also preferable to make the inner wall of the container out of glass or stainless steel.

[0220] <Preparation Method of Coloring Composition> The coloring composition disclosed herein can be prepared by mixing the aforementioned components. When preparing the coloring composition, all components can be dissolved and / or dispersed in a solvent simultaneously to prepare the coloring composition. Alternatively, as needed, each component can be appropriately prepared as two or more solutions or dispersions, and then mixed together before use (during coating) to prepare the coloring composition.

[0221] Furthermore, when preparing coloring compositions, processes including pigment dispersion are preferable.

Furthermore, it is preferable to remove coarse particles after pulverization by filtration, centrifugation, or other methods. Furthermore, regarding the process and dispersing machine for dispersing pigments, the processes and dispersing machines described in "Complete Collection of Dispersion Technology, JOHOKIKO CO.,LTD., July 15, 2005" or "Comprehensive Data Collection on Dispersion Technology and Practical Industrial Applications Centered on Suspension (Solid / Liquid Dispersion Systems), Business Development Center Publishing Department, October 10, 1978" and paragraph 0022 of Japanese Patent Application Publication No. 2015-157893 are preferred. Also, in the process of dispersing pigments, particle refinement can be achieved through a salt milling step. For example, the raw materials, equipment, and processing conditions used in the salt milling step can be found in Japanese Patent Application Publication Nos. 2015-194521 and 2012-046629. Zirconia, agate, quartz, titanium dioxide, tungsten carbide, silicon nitride, alumina, stainless steel, glass, or combinations thereof can be used as microbeads for dispersion. Inorganic compounds with a Mohs hardness of 2 or higher can also be used. The composition may contain 1 to 10,000 ppm of the aforementioned microbeads.

[0222] When preparing a coloring composition, it is preferable to filter the coloring composition using a filter to remove impurities or reduce defects. As long as the filter is one that has been used for filtration purposes, it can be used without particular restrictions. Examples of filters made from materials such as fluoropolymers like polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF), polyamide resins like nylon (e.g., nylon-6, nylon-6,6), and polyolefin resins like polyethylene and polypropylene (PP) (including high-density and ultra-high molecular weight polyolefin resins) are also acceptable. Among these materials, polypropylene (including high-density polypropylene) and nylon are preferred.

[0223] A filter pore size of 0.01μm to 7.0μm is preferred, 0.01μm to 3.0μm is more preferred, and 0.05μm to 0.5μm is even more preferred. As long as the filter pore size is within the above range, fine impurities can be removed more reliably. For filter pore size values, please refer to the filter manufacturer's specifications. Various filters supplied by NIHON PALL Corporation (DFA4201NIEY, DFA4201NAEY, DFA4201J006P, etc.), Advantec Toyo Kaisha, Ltd., Nihon Entegris KK (Formerly Nippon Mykrolis Corporation), and KITZ MICROFILTER Corporation can be used.

[0225] When using filters, different filters can be combined (e.g., a first filter and a second filter). Filtration can then be performed once or more than once using each filter. Furthermore, filters with different pore sizes can be combined within the aforementioned range. Alternatively, the first filter can be used only for filtration of the dispersion, and after mixing other components, the second filter can be used for further filtration. Moreover, filters can be appropriately selected based on the hydrophilicity / hydrophobicity of the components.

[0226] (Calmed material and membrane) The hardened material disclosed herein is a hardened material formed by hardening the colored composition disclosed herein. The film disclosed herein is a film obtained from the coloring composition disclosed herein, and it is preferable to form a film by curing the coloring composition disclosed herein. The film disclosed herein can be used in filters such as color filters or infrared transmission filters. In particular, it is preferable to use colored pixels as color filters. Examples of colored pixels include red pixels, green pixels, blue pixels, magenta pixels, cyan pixels, and yellow pixels, with green pixels, red pixels, or blue pixels being preferred, and green pixels being even more preferred.

An upper limit of 10 μm or less is more preferred, 5 μm or less is further preferred, 3 μm or less is further preferred, and 1.5 μm or less is especially preferred. A lower limit of 0.2 μm or more is more preferred, and 0.3 μm or more is further preferred.

[0228] (Methods for manufacturing hardened materials and membranes) The hardened material or film disclosed herein can be manufactured by coating the colored composition disclosed herein onto a support. The method for manufacturing the film preferably includes a step of forming a pattern (pixel). Examples of methods for forming the pattern (pixel) include photolithography and dry etching, with photolithography being preferred.

[0229] The pattern formation based on photolithography preferably includes the following steps: forming a colored composition layer on a support using the colored composition disclosed herein; exposing the colored composition layer in a patterned manner; and developing to remove the unexposed portions of the colored composition layer to form a pattern (pixel). Depending on the need, a step of baking the colored composition layer (pre-baking step) and a step of baking the developed pattern (pixel) can also be included (post-baking step).

[0230] In the step of forming the colored composition layer, the colored composition disclosed herein is used to form the colored composition layer on a support. There are no particular limitations on the support, and it can be appropriately selected according to the application. Examples include glass substrates and silicon substrates, with silicon substrates being preferred. Furthermore, charge-coupled devices (CCDs), complementary metal-oxide-semiconductor (CMOS) films, transparent conductive films, etc., can be formed on the silicon substrate. Sometimes, a black matrix is ​​formed on the silicon substrate to isolate each pixel. Furthermore, to improve adhesion to the upper layer, prevent material diffusion, or planarize the substrate surface, a base layer can be provided on the silicon substrate. The base layer can also be formed using a composition from the colored composition described in this specification with the colorant removed, or a composition containing the resin, polymeric compound, surfactant, etc., described in this specification. When measured with diiodomethane, a surface contact angle of 20° to 70° is preferred for the base layer. When measured with water, 30° to 80° is preferred.

[0231] As a coating method for the coloring composition, known methods can be used. Examples include drop casting; slot coating; spraying; roller coating; spin coating; cast coating; slot spin coating; pre-wetting (e.g., the method described in Japanese Patent Application Publication No. 2009-145395); inkjet printing (e.g., on-demand, piezoelectric, thermal), nozzle jetting and other ejection systems; flexographic printing, screen printing, gravure printing, reverse offset printing, metal mask printing and other methods; transfer methods using molds, etc.; nanoimprinting, etc. There are no particular limitations on the application methods in inkjet printing. For example, the methods described in "Inkjet Printing That Can Be Promoted and Used - Infinite Possibilities Appearing in Patents - Published February 2005, Sumitbe Techon Research Co., Ltd." (especially pages 115-133) or those described in Japanese Patent Application Publication Nos. 2003-262716, 2003-185831, 2003-261827, 2012-126830, and 2006-169325 can be cited. Furthermore, regarding the coating method of the coloring composition, please refer to International Publication Nos. 2017 / 030174 and 2017 / 018419, the contents of which are incorporated in this specification.

[0232] The colored composition layer formed on the support can be dried (pre-baked). When the film is manufactured using a low-temperature process, pre-baking is not necessary. When pre-baking is performed, a pre-baking temperature of 150°C or below is preferred, 120°C or below is more preferred, and 110°C or below is even more preferred. The lower limit can be set to 50°C or above, or 80°C or above. A pre-baking time of 10 to 300 seconds is preferred, 40 to 250 seconds is more preferred, and 80 to 220 seconds is even more preferred. Pre-baking can be performed using a heating plate, oven, or similar equipment.

[0233] Next, the colored composition layer is exposed in a pattern (exposure step). For example, using a stepper or scanning exposure machine, the colored composition layer is exposed through a mask with a predetermined mask pattern, thereby enabling patterned exposure. This allows the exposed areas to harden.

[0234] Examples of radiation (light) that can be used during exposure include gamma rays and i-rays. Light with wavelengths below 300 nm can also be used (preferably light with wavelengths between 180 nm and 300 nm). Examples of light with wavelengths below 300 nm include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm), with KrF rays (wavelength 248 nm) being preferred. Furthermore, light sources with wavelengths above 300 nm can also be used.

[0235] Furthermore, during exposure, exposure can be performed by continuous illumination or by pulsed illumination (pulse exposure). Moreover, pulse exposure is an exposure method that involves repeatedly illuminating and pausing light for short periods of time (e.g., less than milliseconds).

[0236] The irradiation dose (exposure dose) is preferably 0.03 J / cm² to 2.5 J / cm², and more preferably 0.05 J / cm² to 1.0 J / cm². Regarding the oxygen concentration during exposure, it can be appropriately selected. Besides exposure under atmospheric conditions, it can be performed in a low-oxygen environment with an oxygen concentration of less than 19 vol% (e.g., 15 vol%, 5 vol%, or virtually oxygen-free), or in a high-oxygen environment with an oxygen concentration exceeding 21 vol% (e.g., 22 vol%, 30 vol%, or 50 vol%). Furthermore, the exposure illuminance can be appropriately set, preferably within the range of 1,000 W / m² to 100,000 W / m² (e.g., 5,000 W / m², 15,000 W / m², or 35,000 W / m²). Oxygen concentration and exposure illuminance can be appropriately combined, for example, it can be set to an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m², an oxygen concentration of 35% by volume and an illuminance of 20,000 W / m², etc.

[0237] Next, development removes the unexposed portions of the color composition layer to form a pattern (pixels). The removal of the unexposed portions of the color composition layer can be performed using a developing solution. Here, the unexposed portions of the color composition layer from the exposure step dissolve in the developing solution, leaving only the photocured portion. A developing solution temperature of, for example, 20°C to 30°C is preferred. A developing time of 20 seconds to 180 seconds is preferred. Furthermore, to improve residue removal, the step of repeatedly discarding the developing solution every 60 seconds and then supplying fresh developing solution can be repeated several times.

[0238] Developers can include organic solvents and alkaline developers, with alkaline developers being preferred. An alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. Examples of alkaline agents include, for example, organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, hydroxylamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, pyrrole, piperidine, and 1,8-diazabicyclo-[5.4.0]-7-undecene, or inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, and sodium metasilicate. From an environmental and safety perspective, compounds with high molecular weights are preferred as alkaline agents. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001% to 10% by mass, and more preferably 0.01% to 1% by mass. Furthermore, the developer may further contain surfactants. From the viewpoint of convenient transportation or storage, the developer can be temporarily prepared as a concentrated solution and diluted to the required concentration before use. There is no particular limitation on the dilution ratio; for example, it can be set in the range of 1.5 to 100 times. Also, rinsing with pure water after development is preferable. Furthermore, rinsing is preferably performed by rotating the support on which the developed colored composition layer has been formed and supplying rinsing solution to the developed colored composition layer. Also, rinsing is preferably performed by moving the nozzle dispensing the rinsing solution from the center of the support to the periphery of the support. In this case, when moving the nozzle from the center of the support to the periphery, the moving speed of the nozzle can be gradually reduced. By rinsing in this manner, in-plane deviation during rinsing can be suppressed. Alternatively, the same effect can be achieved by gradually reducing the rotational speed of the support while moving the nozzle from the center to the periphery of the support.

[0239] After development, drying followed by additional exposure and heating (post-baking) is preferable. This additional exposure and post-baking is a post-development curing process used to produce a fully cured film. The heating temperature during post-baking is preferably 100°C to 240°C, and more preferably 200°C to 240°C. The developed film can be post-baked continuously or intermittently using heating mechanisms such as heating plates, convection ovens (hot air circulating dryers), or high-frequency heaters, in accordance with the above conditions. When performing additional exposure, light with a wavelength of 400 nm or less is preferable. Furthermore, the additional exposure can be performed using the method described in Korean Patent Publication No. 10-2017-0122130.

[0240] The preferred method for forming patterns by dry etching includes the following steps: forming a colored composition layer on a support using the colored composition disclosed herein, and hardening the entire colored composition layer to form a hardened layer; forming a photoresist layer on the hardened layer; exposing the photoresist layer in a patterned manner, followed by development to form a resist pattern; and using the resist pattern as a mask to perform dry etching on the hardened layer using an etching gas. It is preferable to further perform a pre-baking process when forming the photoresist layer. In particular, it is preferable to perform a post-exposure heating process and a post-development heating process (post-baking process) as the photoresist layer formation process. For details on forming patterns by dry etching, please refer to paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, which is incorporated herein by reference.

An upper limit of 5.0μm or less is preferred, 2.0μm or less is further preferred, 1.0μm or less is excellent, and 0.8μm or less is optimal. Furthermore, the Young's modulus of the pixels is preferably 0.5GPa to 20GPa, and 2.5GPa to 15GPa is even better.

[0244] The pixels included in the filter preferably have high flatness. Specifically, a pixel surface roughness Ra of 100 nm or less is preferred, 40 nm or less is even better, and 15 nm or less is further preferred. There is no specified lower limit, but for example, 0.1 nm or more is preferred. The pixel surface roughness can be measured, for example, using a Veeco AFM (Atomic Force Microscope) Dimension 3100. Furthermore, the water contact angle on the pixel can be appropriately set to a preferred value, typically in the range of 50° to 110°. The contact angle can be measured, for example, using a contact angle meter CV-DT･A type (manufactured by Kyowa Interface Science Co., LTD.). Also, a high pixel volume resistivity is preferred. Specifically, a pixel volume resistivity of 10⁹ Ω･cm or more is preferred, and 10¹¹ Ω･cm or more is even better. There is no specified upper limit, but for example, 10¹⁴ Ω･cm or less is preferred. The volume resistivity of a pixel can be measured using an ultra-high resistance meter 5410 (manufactured by Advantest Corporation).

[0245] In a filter, a protective layer can be formed on the surface of the film disclosed herein. By forming a protective layer, various functions can be imparted, such as oxidation resistance, low reflectivity, hydrophilicity / hydrophobicity, and shielding of specific wavelengths of light (ultraviolet, near-infrared, etc.). The thickness of the protective layer is preferably 0.01 μm to 10 μm, and more preferably 0.1 μm to 5 μm. Methods for forming the protective layer include methods such as coating with a composition for forming a protective layer, chemical vapor deposition, and attaching the molded resin with an adhesive material. Examples of components constituting the protective layer include (meth)acrylic resin, olefin-thiol resin, polycarbonate resin, polyether resin, polyaryl ester resin, polyurethane resin, polyetherurethane resin, polystyrene resin, polyaryl ether phosphine oxide resin, polyimide resin, polyamide-amide resin, polyolefin resin, cyclic olefin resin, polyester resin, styrene resin, polyol resin, polyvinylidene chloride resin, melamine resin, polyurethane resin, aromatic polyamide resin, polyamide resin, alkyd resin, epoxy resin, modified polysiloxane resin, fluororesin, polycarbonate resin, polyacrylonitrile resin, cellulose resin, Si, C, W, Al₂O₃, Mo, SiO₂, Si₂N₄, etc., and may contain two or more of these components. For example, in the case of a protective layer used for oxidation inhibition, it is preferable that the protective layer contains polyol resin, SiO₂, and Si₂N₄. Furthermore, in the case of a protective layer used for low reflectivity, it is preferable that the protective layer contains (meth)acrylic resin and fluoropolymer resin.

[0246] Depending on the requirements, the protective layer may contain additives such as organic / inorganic particles, absorbers for specific wavelengths of light (e.g., ultraviolet, near-infrared, etc.), refractive index modifiers, antioxidants, adhesives, and surfactants. Examples of organic / inorganic particles include polymer particles (e.g., polysiloxane microparticles, polystyrene microparticles, melamine resin microparticles), titanium dioxide, zinc oxide, zirconium oxide, indium oxide, aluminum oxide, titanium nitride, titanium oxynitride, magnesium fluoride, hollow silica, silicon dioxide, calcium carbonate, and barium sulfate. Known absorbers can be used for the specific wavelengths of light. The content of these additives can be appropriately adjusted, but 0.1% to 70% by mass relative to the total mass of the protective layer is preferred, and 1% to 60% by mass is further preferred.

[0247] Furthermore, as a protective layer, the protective layer described in paragraphs 0073 to 0092 of Japanese Patent Application Publication No. 2017-151176 can also be used.

[0248] The filter can also have the following structure: each pixel is embedded in a space separated by partitions, such as a grid.

[0249] (Image sensor) The image sensor disclosed herein has the membrane disclosed herein. Examples of image sensors include solid-state imaging elements, X-ray imaging elements, and organic thin-film imaging elements. Among these, solid-state imaging elements are particularly well-suited for use. The solid-state imaging element disclosed herein contains the film disclosed herein. As for the structure of the solid-state imaging element, there is no particular limitation as long as it is a structure that functions as a solid-state imaging element, but the following structures can be cited as examples.

[0250] The structure of the imaging element is as follows: A substrate has a plurality of photodiodes (such as CCD (charge-coupled device) image sensors, CMOS (complementary metal oxide semiconductor) image sensors, and a transmission electrode formed of polysilicon, constituting the light-receiving area of ​​a solid-state imaging element (CCD image sensor, CMOS image sensor, etc.). A light-shielding film with openings only in the light-receiving portion of the photodiodes is provided on the photodiodes and the transmission electrode. An element protective film formed of silicon nitride, etc., is provided on the light-shielding film to cover the entire surface of the film and the light-receiving portion of the photodiodes. A color filter is provided on the element protective film. Furthermore, the structure may have a light-gathering mechanism (e.g., a microlens, etc. The same applies hereinafter) on the device protective film and on the underside (near the substrate) of the color filter, or a structure with a light-gathering mechanism on the color filter, etc. Furthermore, the color filter can also have a structure in which each colored pixel is embedded in a space separated by partitions, for example, in a grid pattern.

[0342] [Lightfastness Evaluation] The coloring compositions of the examples and comparative examples described in Tables 13 to 21 above were coated onto a glass substrate using a spin coating method. Then, a pre-baking process (heating at 100°C for 120 seconds) was performed, followed by exposure to i-rays at an exposure dose of 1,000 mJ / cm², and then heating at 200°C for 5 minutes, thereby producing a film with a thickness of 0.6 μm. The transmittance and its integral value in the wavelength range of 400 nm to 700 nm were measured using an MCPD-3000 manufactured by OTSUKA ELECTRONICS Co., Ltd. Next, the film prepared above was irradiated with 100,000 Lux of light for 2,000 hours (total irradiation dose of 200 million Lux·hr) using a lightfastness testing machine (Super Xenon Weather Meter SX75, manufactured by Suga Test Instruments Co., Ltd.). The lightfastness was evaluated by measuring the transmittance and integral value of the film after light irradiation, using the following criteria. A: The integral of the transmittance of the film after light irradiation at wavelengths of 400nm to 700nm is more than 98% of the integral of the transmittance of the film before light irradiation at wavelengths of 400nm to 700nm. B: The integral of the transmittance of the film after light irradiation in the wavelength range of 400nm to 700nm is more than 95% but less than 98% of the integral of the transmittance of the film before light irradiation in the wavelength range of 400nm to 700nm. C: The integral of the transmittance of the film after light irradiation at wavelengths of 400nm to 700nm is more than 93% but less than 95% of the integral of the transmittance of the film before light irradiation at wavelengths of 400nm to 700nm. D: The integral of the transmittance of the film after light irradiation in the wavelength range of 400nm to 700nm is more than 90% but less than 93% of the integral of the transmittance of the film before light irradiation in the wavelength range of 400nm to 700nm. E: The integral of the transmittance of the film after light irradiation at wavelengths of 400nm to 700nm is less than 90% of the integral of the transmittance of the film before light irradiation at wavelengths of 400nm to 700nm.

[0343] [Stability over time] The viscosity of the coloring compositions of the examples and comparative examples described in Tables 13 to 21 above was measured after fresh manufacturing. The viscosity of the coloring compositions was measured after being stored in a constant temperature bath at 45°C for 72 hours. Furthermore, the viscosity was measured again after adjusting the temperature of the coloring composition to 23°C. The viscosity increase rate was calculated using the following formula, and the storage stability was evaluated. Viscosity increase rate (%) = ((Viscosity of the coloring composition after 72 hours of storage in a constant temperature bath at 45℃ / Viscosity of the freshly manufactured coloring composition) - 1) × 100 A: The viscosity-increasing rate of the coloring composition is less than 5%. B: The viscosity increase rate of the coloring composition exceeds 5% but is less than 7.5%. C: The viscosity increase rate of the coloring composition exceeds 7.5% and is less than 10%. D: The viscosity increase rate of the coloring composition exceeds 10%.
