[0005] In recent years, for devices equipped with optical filters such as color filters, the requirements for long-term reliability have been increasing. For this reason, the films used for optical filters are also required to be excellent in long-term reliability.

[0006] On the other hand, when a pixel is formed using a coloring composition containing a colorant and such an optical filter containing such pixels is exposed to a high-temperature and high-humidity environment for a long time, components such as the colorant contained in the pixel may move to a member (such as pixels of other colors) adjacent to the pixel. For this reason, the long-term reliability of the film obtained with conventionally known coloring compositions has not been sufficient, and there has been room for improvement.

[0007] Further, according to the study by the present inventor, it has been found that the long-term reliability of the film obtained using the coloring composition described in the example of Patent Document 1 is not sufficient and there is room for improvement.

Specific examples of the organic solvent include polyethylene glycol monomethyl ether, dichloromethane, methyl 3-ethoxypropionate, ethyl 3-ethoxypropionate, ethyl cellosolve acetate, ethyl lactate, diethylene glycol dimethyl ether, butyl acetate, methyl 3-methoxypropionate, 2-heptanone, cyclohexanone, cyclohexyl acetate, cyclopentanone, ethyl carbitol acetate, butyl carbitol acetate, propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate, 3-methoxy-N,N-dimethylpropanamide, 3-butoxy-N,N-dimethylpropanamide and the like. However, aromatic hydrocarbons (benzene, toluene, xylene, ethylbenzene, etc.) as organic solvents may preferably be reduced for reasons such as environmental aspects (for example, it can be 50 ppm (parts per million) or less, 10 ppm or less, or 1 ppm or less based on the total amount of the organic solvent).

[0091] In the present invention, it is preferable to use an organic solvent having a low metal content, and the metal content of the organic solvent is preferably, for example, 10 mass ppb (parts per billion) or less. If necessary, an organic solvent at the mass ppt (parts per trillion) level may be used. Such an organic solvent is provided by, for example, Toyo Gosei Co., Ltd. (Chemical Industry Daily, November 13, 2015).

[0092] Examples of methods for removing impurities such as metals from the organic solvent include distillation (such as molecular distillation and thin-film distillation) and filtration using a filter. The filter pore size of the filter used for filtration is preferably 10 μm or less, more preferably 5 μm or less, and even more preferably 3 μm or less.

[0095] The content of the solvent in the coloring composition is preferably 10 to 95% by mass, more preferably 20 to 90% by mass, and even more preferably 30 to 90% by mass.

[0096] In addition, from the perspective of environmental regulations, it is preferable that the coloring composition of the present invention substantially does not contain environmentally regulated substances. In the present invention, substantially not containing environmentally regulated substances means that the content of environmentally regulated substances in the coloring composition is 50 mass ppm or less, preferably 30 mass ppm or less, more preferably 10 mass ppm or less, and particularly preferably 1 mass ppm or less. Examples of environmentally regulated substances include benzene; alkylbenzenes such as toluene and xylene; halogenated benzenes such as chlorobenzene. These are registered as environmentally regulated substances under regulations such as the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) Regulation, the PRTR (Pollutant Release and Transfer Register) Law, and the VOC (Volatile Organic Compounds) Regulation, and their usage amounts and handling methods are strictly regulated. These compounds may be used as solvents when manufacturing each component used in the coloring composition, etc., and may be mixed into the coloring composition as residual solvents. From the viewpoints of safety to humans and consideration for the environment, it is preferable to reduce these substances as much as possible. As a method for reducing environmentally regulated substances, there is a method of heating or reducing the pressure in the system to a temperature above the boiling point of the environmentally regulated substances and distilling off the environmentally regulated substances from the system for reduction. Also, when distilling off a small amount of environmentally regulated substances, it is also useful to azeotrope with a solvent having a boiling point equivalent to that of the corresponding solvent in order to improve efficiency. Further, when containing a compound having radical polymerizability, a polymerization inhibitor or the like may be added and distilled off under reduced pressure in order to suppress the progress of the radical polymerization reaction and crosslinking between molecules during distillation under reduced pressure. These distillation methods are possible at any stage, such as at the raw material stage, at the stage of the product obtained by reacting the raw materials (for example, a resin solution or a polyfunctional monomer solution after polymerization), or at the stage of the coloring composition prepared by mixing these compounds.

[0097] <<Pigment Derivative>> The coloring composition of the present invention can contain a pigment derivative. Examples of the pigment derivative include compounds having a structure in which an acid group or a basic group is bonded to a dye skeleton. Examples of the dye skeleton constituting the pigment derivative include a quinoline dye skeleton, a benzimidazolone dye skeleton, a benzisoindole dye skeleton, a benzothiazole dye skeleton, an iminium dye skeleton, a squarylium dye skeleton, a croconium dye skeleton, an oxonol dye skeleton, a pyrrolopyrrole dye skeleton, a diketopyrrolopyrrole dye skeleton, an azo dye skeleton, an azomethine dye skeleton, a phthalocyanine dye skeleton, a naphthalocyanine dye skeleton, an anthraquinone dye skeleton, a quinacridone dye skeleton, a dioxazine dye skeleton, a perinone dye skeleton, a perylene dye skeleton, a thioindigo dye skeleton, an isoindoline dye skeleton, an isoindolinone dye skeleton, a quinophthalone dye skeleton, an iminium dye skeleton, a dithiol dye skeleton, a triarylmethane dye skeleton, a pyromethene dye skeleton, and the like. Examples of the acid group include a sulfo group, a carboxyl group, a phosphate group, and salts thereof. Examples of the atom or atomic group constituting the salt include an alkali metal ion (Li + , Na + , K + , etc.), an alkaline earth metal ion (Ca 2+ , Mg 2+ , etc.), an ammonium ion, an imidazolium ion, a pyridinium ion, a phosphonium ion, and the like. Examples of the basic group include an amino group, a pyridinyl group and its salt, a salt of an ammonium group, and a phthalimidomethyl group. Examples of the atom or atomic group constituting the salt include a hydroxide ion, a halogen ion, a carboxylate ion, a sulfonate ion, a phenoxide ion, and the like.

[0098] In addition, as the pigment derivative, it is also preferable to use a compound having a structure with a triazine skeleton and an acid group or a basic group. Since the structure of the triazine skeleton of the pigment derivative is similar to that of the pteridine skeleton of the pteridine pigment, the pigment derivative is likely to adsorb on the surface of the pteridine pigment. As a result, it is presumed that a strong network is formed among the pteridine pigment, the pigment derivative, and the resin. By forming such a network, the dispersibility of the pteridine pigment in the coloring composition can be further improved, and the temporal stability of the coloring composition can be further improved. Furthermore, it is easy to form a film with suppressed occurrence of defects. Also, when the network between the pigment and the resin becomes strong, the pigment is more likely to be developed together with the resin, and the developability can be further improved.

[0099] The coloring composition may also contain a pigment derivative having excellent visible transparency (hereinafter also referred to as a transparent pigment derivative).

[0171] <Method for manufacturing the film> Next, the method for manufacturing the film of the present invention will be described. The film of the present invention can be manufactured through the step of applying the coloring composition of the present invention. In the method for manufacturing the film, it is preferably further included a step of forming a pattern (pixel). Examples of the method for forming the pattern (pixel) include a photolithography method and a dry etching method, and the photolithography method is preferred.

[0172] Pattern formation by photolithography preferably includes a step of forming a colored composition layer on a support using the colored composition of the present invention, a step of exposing the colored composition layer in a pattern, and a step of developing and removing the unexposed portion of the colored composition layer to form a pattern (pixel). If necessary, a step of baking the colored composition layer (pre-baking step) and a step of baking the developed pattern (pixel) (post-baking step) may be provided.

[0173] In the step of forming the colored composition layer, a colored composition layer is formed on a support using the colored composition of the present invention. The support is not particularly limited and can be appropriately selected according to the application. For example, a glass substrate, a silicon substrate, etc. may be mentioned, and a silicon substrate is preferred. Further, a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), a transparent conductive film, etc. may be formed on the silicon substrate. Further, a black matrix for isolating each pixel may be formed on the silicon substrate. Further, a base layer may be provided on the silicon substrate for improving adhesion to the upper layer, preventing diffusion of substances, or flattening the substrate surface. The base layer may be formed using a composition obtained by removing a colorant from the colored composition described in this specification, a composition containing a curable compound, a surfactant, etc. described in this specification. The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane. Further, it is preferably 30 to 80° when measured with water. If the surface contact angle of the base layer is within the above range, the coatability of the resin composition is good. The adjustment of the surface contact angle of the base layer can be performed by a method such as adding a surfactant.

[0174] As a method for applying the coloring composition, known methods can be used. For example, the drop casting method; the slit coating method; the spray method; the roll coating method; the spin coating method; the casting coating method; the slit and spin method; the dip coating method (for example, the method described in JP-A-2009-145395); ejection system printing such as inkjet (for example, on-demand type, piezo type, thermal type), nozzle jet, flexographic printing, screen printing, gravure printing, reverse offset printing, metal mask printing method, and other various printing methods; a transfer method using a mold or the like; a nanoimprint method, etc. The application method in inkjet is not particularly limited, and for example, the method shown in "Spreadable and Usable Inkjet - Infinite Possibilities in Patents - Published in February 2005, Sumitomo Precision Products Co., Ltd." (particularly pages 115 to 133), and the methods described in JP-A-2003-262716, JP-A-2003-185831, JP-A-2003-261827, JP-A-2012-126830, JP-A-2006-169325, etc. can be mentioned. Further, regarding the method for applying the coloring composition, the descriptions of WO 2017 / 030174 and WO 2017 / 018419 can be referred to, and the contents thereof are incorporated herein.

[0175] The coloring composition layer formed on the support may be dried (pre-baked). When manufacturing a film by a low-temperature process, pre-baking may not be necessary. When pre-baking is performed, the pre-baking temperature is preferably 150°C or lower, more preferably 120°C or lower, and even more preferably 110°C or lower. The lower limit can be, for example, 50°C or higher, and can also be 80°C or higher. The pre-baking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and even more preferably 80 to 220 seconds. Pre-baking can be performed on a hot plate, in an oven, or the like.

[0176] Next, the colored composition layer is exposed in a pattern (exposure step). For example, the colored composition layer can be exposed in a pattern by exposing it through a mask having a predetermined mask pattern using a stepper exposure machine, a scanner exposure machine, or the like. Thereby, the exposed portion can be cured.

[0177] Examples of the radiation (light) that can be used for exposure include g-line, i-line, etc. Also, light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) can be used. Examples of light with a wavelength of 300 nm or less include KrF line (wavelength 248 nm), ArF line (wavelength 193 nm), etc., and KrF line (wavelength 248 nm) is preferred. Also, light sources with longer wavelengths of 300 nm or more can be used.

[0178] Also, at the time of exposure, the light may be continuously irradiated for exposure, or may be irradiated pulsatively for exposure (pulse exposure). Note that pulse exposure is an exposure method in which light irradiation and pause are repeated in a short time cycle (for example, at the millisecond level or less) for exposure.

[0179] The irradiation amount (exposure amount) is, for example, preferably 0.03 to 2.5 J / cm 2 and more preferably 0.05 to 1.0 J / cm 2 The oxygen concentration during exposure can be appropriately selected. In addition to performing it in the atmosphere, for example, it may be exposed in a low oxygen atmosphere with an oxygen concentration of 19% by volume or less (for example, 15% by volume, 5% by volume, or substantially oxygen-free), or in a high oxygen atmosphere with an oxygen concentration exceeding 21% by volume (for example, 22% by volume, 30% by volume, or 50% by volume). Also, the exposure illuminance can be appropriately set, and is usually 1000 W / m 2 ~100000 W / m 2 (for example, 5000 W / m 2 , 15000 W / m 2 , or 35000 W / m 2 ) and can be selected from the range. The oxygen concentration and the exposure illuminance can be appropriately combined. For example, an oxygen concentration of 10% by volume and an illuminance of 10000 W / m 2, an oxygen concentration of 35% by volume and an illuminance of 20000 W / m 2 and the like can be used.

[0180] Next, the unexposed portion of the colored composition layer is developed and removed to form a pattern (pixel). The development and removal of the unexposed portion of the colored composition layer can be performed using a developer. As a result, the unexposed portion of the colored composition layer in the exposure step is eluted in the developer, and only the photocured portion remains. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. Further, in order to improve the residue removability, the developer may be shaken off every 60 seconds, and the step of supplying a new developer may be repeated several times.

[0181] The developing solution includes organic solvents, alkaline developing solutions, etc., and an alkaline developing solution is preferably used. As the alkaline developing solution, an alkaline aqueous solution (alkaline developing solution) obtained by diluting an alkaline agent with pure water is preferred. Examples of the alkaline agent include organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxyamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, pyrrole, piperidine, 1,8-diazabicyclo-[5.4.0]-7-undecene, and inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium hydrogen carbonate, sodium silicate, and sodium metasilicate. Alkaline agents with larger molecular weights are preferred in terms of environmental and safety aspects. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. Further, the developing solution may further contain a surfactant. From the viewpoints of convenience in transportation and storage, etc., the developing solution may be once manufactured as a concentrated solution and diluted to the required concentration at the time of use. The dilution ratio is not particularly limited, but can be set, for example, in the range of 1.5 to 100 times. Also, it is preferable to wash (rinse) with pure water after development. Further, the rinsing is preferably performed by supplying a rinse solution to the colored composition layer after development while rotating the support on which the colored composition layer after development is formed. Also, it is preferable to move the nozzle for discharging the rinse solution from the central part of the support to the peripheral part of the support. At this time, when moving the nozzle from the central part to the peripheral part of the support, the moving speed of the nozzle may be gradually decreased while moving. By performing rinsing in this way, the in-plane variation of the rinsing can be suppressed. Also, the same effect can be obtained by gradually decreasing the rotation speed of the support while moving the nozzle from the central part to the peripheral part of the support.

[0182] After development, it is preferable to perform additional exposure treatment or heat treatment (post-baking) after drying. The additional exposure treatment and post-baking are post-development curing treatments for making the curing complete. The heating temperature in post-baking is preferably, for example, 100 to 240 °C, more preferably 200 to 240 °C. Post-baking can be carried out continuously or batchwise using heating means such as a hot plate, a convection oven (hot air circulation dryer), a high-frequency heater, etc. so that the film after development becomes the above conditions. When performing the additional exposure treatment, the light used for exposure is preferably light with a wavelength of 400 nm or less. Also, the additional exposure treatment may be carried out by the method described in Korean Patent Publication No. 10-2017-0122130.

[0183] For pattern formation by the dry etching method, a step of forming a colored composition layer on a support using the colored composition of the present invention and curing the entire colored composition layer to form a cured product layer, a step of forming a photoresist layer on this cured product layer, a step of exposing the photoresist layer in a pattern and then developing it to form a resist pattern, and a step of dry etching the cured product layer using an etching gas with this resist pattern as a mask are preferably included. In the formation of the photoresist layer, it is preferable to further perform a pre-baking treatment. In particular, as the photoresist layer formation process, a form in which heat treatment after exposure and heat treatment after development (post-baking treatment) are carried out is desirable. Regarding pattern formation by the dry etching method, the descriptions in paragraphs 0010 to 0067 of JP-A-2013-064993 can be referred to, and this content is incorporated herein.

[0184] <Optical Filter> The optical filter of the present invention has the film of the present invention described above. Examples of the type of optical filter include a color filter and an infrared transmission filter, and it is preferably a color filter. As the color filter, it is preferable to have the film of the present invention as the colored pixel of the color filter.

[0185] The optical filter may have a protective layer provided on the surface of the film of the present invention. By providing the protective layer, various functions such as oxygen barrier, antireflection, hydrophilic / hydrophobic modification, and shielding of light of specific wavelengths (ultraviolet rays, near-infrared rays, etc.) can be imparted. The thickness of the protective layer is preferably 0.01 to 10 μm, more preferably 0.1 to 5 μm. Examples of the method for forming the protective layer include a method of applying a resin composition dissolved in an organic solvent, a chemical vapor deposition method, and a method of attaching a molded resin with an adhesive. Examples of the components constituting the protective layer include (meth)acrylic resin, ene-thiol resin, polycarbonate resin, polyether resin, polyarylate resin, polysulfone resin, polyethersulfone resin, polyphenylene resin, polyarylene ether phosphine oxide resin, polyimide resin, polyamideimide resin, polyolefin resin, cyclic olefin resin, polyester resin, styrene resin, polyol resin, polyvinylidene chloride resin, melamine resin, urethane resin, aramid resin, polyamide resin, alkyd resin, epoxy resin, modified silicone resin, fluororesin, polycarbonate resin, polyacrylonitrile resin, cellulose resin, Si, C, W, Al2O3, Mo, SiO2, Si2N4, etc. Two or more of these components may be contained. For example, in the case of a protective layer for the purpose of oxygen barrier, the protective layer preferably contains a polyol resin, SiO2, and Si2N4. Also, in the case of a protective layer for the purpose of antireflection, the protective layer preferably contains a (meth)acrylic resin and a fluororesin.

[0186] When forming the protective layer by applying a resin composition, known methods such as spin coating, casting, screen printing, and inkjet can be used as the application method of the resin composition. Known organic solvents (for example, propylene glycol 1-monomethyl ether 2-acetate, cyclopentanone, ethyl lactate, etc.) can be used as the organic solvent contained in the resin composition. When forming the protective layer by chemical vapor deposition, known chemical vapor deposition methods (thermal chemical vapor deposition, plasma chemical vapor deposition, photochemical vapor deposition) can be used as the chemical vapor deposition method.

[0187] The protective layer may contain additives such as organic and inorganic fine particles, absorbents for light of specific wavelengths (e.g., ultraviolet rays, near-infrared rays, etc.), refractive index adjusters, antioxidants, adhesives, surfactants, etc., if necessary. Examples of the organic and inorganic fine particles include, for example, polymer fine particles (e.g., silicone resin fine particles, polystyrene fine particles, melamine resin fine particles), titanium oxide, zinc oxide, zirconium oxide, indium oxide, aluminum oxide, titanium nitride, oxynitride titanium, magnesium fluoride, hollow silica, silica, calcium carbonate, barium sulfate, etc. Known absorbents can be used as the absorbent for light of specific wavelengths. The content of these additives can be adjusted as appropriate, but is preferably 0.1 to 70% by mass, more preferably 1 to 60% by mass, based on the total mass of the protective layer.

[0188] Also, as the protective layer, the protective layer described in paragraphs 0073 to 0092 of JP-A-2017-151176 can also be used.

[0189] The optical filter may have a structure in which each pixel is embedded in a space partitioned, for example, in a lattice shape by a partition wall.

[0190] <Solid-state imaging device> The solid-state imaging device of the present invention has the film of the present invention described above. The configuration of the solid-state imaging device is not particularly limited as long as it includes the film of the present invention and functions as a solid-state imaging device. For example, the following configurations can be mentioned.

[0191] On a substrate, there are a plurality of photodiodes constituting a light-receiving area of a solid-state imaging device (such as a CCD (charge-coupled device) image sensor, a CMOS (complementary metal-oxide semiconductor) image sensor, etc.) and transfer electrodes made of polysilicon or the like. There is a light-shielding film with an opening only in the light-receiving part of the photodiode on the photodiode and the transfer electrodes. On the light-shielding film, there is a device protection film made of silicon nitride or the like formed to cover the entire surface of the light-shielding film and the light-receiving part of the photodiode. On the device protection film, there is a configuration having a color filter. Further, it may be a configuration having condensing means (for example, a microlens or the like. The same applies hereinafter) on the device protection film and below the color filter (the side closer to the substrate), or a configuration having condensing means on the color filter. Also, the color filter may have a structure in which each colored pixel is embedded in a space partitioned, for example, in a lattice shape by partition walls. In this case, it is preferable that the partition walls have a low refractive index with respect to each colored pixel. Examples of such an imaging device having such a structure include the devices described in JP-A-2012-227478, JP-A-2014-179577, and International Publication No. 2018 / 043654. Also, as shown in JP-A-2019-211559, an ultraviolet absorption layer may be provided in the structure of the solid-state imaging device to improve light resistance. The imaging device provided with the solid-state imaging device of the present invention can be used not only for a digital camera and an electronic device having an imaging function (such as a mobile phone), but also for an in-vehicle camera and a surveillance camera.

[0224] (Performance evaluation of the coloring composition) [Long-term reliability evaluation] After the coloring composition described in the above table was spin-coated on an 8-inch (20.32 cm) glass wafer to a thickness of 0.65 μm after post-baking, it was heated on a hot plate at 100 °C for 2 minutes to form a coloring composition layer. Then, using an i-line stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Inc.), through a mask having a Bayer pattern, 300 mJ / cm 2The coloring composition layer was exposed with the exposure amount described above. Subsequently, paddle development was performed on the coloring composition layer at 23 °C for 60 seconds using a 0.3 mass% aqueous solution of tetramethylammonium hydroxide (TMAH). Thereafter, rinsing by spin shower and water washing using pure water were carried out, and further, heating (post-baking) was performed at 200 °C for 5 minutes using a hot plate to form the first pixel on the glass wafer. Subsequently, a radiation-sensitive composition described in paragraph number 0231 of JP-A-2013-254047 was used, and development and exposure were performed in the same manner as for the formation of the first pixel, and a second pixel (transparent pixel) was formed in the missing portion of the Bayer pattern of the first pixel on the glass wafer. Using a microscopic spectrophotometer ("OSP-SP200" manufactured by Olympus Optical Co., Ltd.), the transmittance (initial spectroscopy) of light with a wavelength of 400 to 700 nm of the second pixel was measured. Next, after performing a reliability test by leaving the glass wafers on which the first pixel and the second pixel were respectively formed stationary for 1500 hours under the conditions of a temperature of 85 °C and a relative humidity of 85%, using a microscopic spectrophotometer ("OSP-SP200" manufactured by Olympus Optical Co., Ltd.), the transmittance (spectroscopy after the reliability test) of light with a wavelength of 400 to 700 nm of the second pixel at a position 2 μm away from the boundary with the first pixel was measured. The change amount of the transmittance of light with a wavelength of 400 to 700 nm of the second pixel before and after the test (= |transmittance (%) of the second pixel before the reliability test - transmittance (%) of the second pixel after the reliability test|) was calculated, and the maximum value (ΔT max1 ) was obtained, and the long-term reliability was evaluated according to the following criteria. The smaller the value of ΔT max1 , the better the long-term reliability. 5: ΔT max1 is 0.5% or less 4: ΔT max1 is greater than 0.5% and 1% or less 3: ΔT max1 is greater than 1% and 3% or less 2: ΔT max1 is greater than 3% and 5% or less 1: ΔT max1 is greater than 5%

[0225] [Light resistance evaluation] The coloring composition described in the above table was spin-coated onto an 8-inch (20.32 cm) glass wafer to a thickness of 0.65 μm after post-baking, and then heated on a hot plate at 100 °C for 2 minutes to form a coloring composition layer. Next, using an i-line stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Inc.), the coloring composition layer was exposed at an exposure dose of 300 mJ / cm 2 . Subsequently, a 0.3 mass% aqueous solution of tetramethylammonium hydroxide (TMAH) was used to perform paddle development on the composition layer at 23 °C for 60 seconds. Thereafter, rinsing with a spin shower and washing with pure water were carried out, and further, heating (post-baking) was performed on a hot plate at 200 °C for 5 minutes to form a film. The transmittance of the obtained film was measured using an MCPD3700 (manufactured by Otsuka Electronics Co., Ltd.). For the above film, a light resistance test was conducted by irradiating light at an illuminance of 100,000 lux for 1500 hours using a super xenon weather meter SX75 (manufactured by Suga Test Instruments Co., Ltd.). The transmittance of the film after the light resistance test was measured using an MCPD3700 (manufactured by Otsuka Electronics Co., Ltd.). The change amount of the transmittance of light with wavelengths from 400 to 700 nm of the film before and after the test (= |transmittance of the film before the light resistance test (%) - transmittance of the film after the light resistance test (%)|) was calculated, and the maximum value (ΔT max2 ) was obtained, and the light resistance was evaluated according to the following criteria. The smaller the value of ΔT max2 , the better the light resistance. 5: ΔT max2 is 5% or less 4: ΔT max2 is greater than 5% and 10% or less 3: ΔT max2 is greater than 10% and 20% or less 2: ΔT max2 is greater than 20% and 25% or less 1: ΔT max2 is greater than 25% and 30% or less 0: ΔT max2 is greater than 30%

[0226] The evaluation results of long-term reliability and light resistance are shown in the following table. The content of the yellow colorant in the colorants used in each coloring composition (the yellow colorant ratio in the table) and the content of the azomethine metal complex in the yellow colorant (the azomethine metal complex ratio in the table) are also shown. Further, after the coloring compositions of Examples 1 to 28 and 32 to 40 were applied on an 8-inch (20.32 cm) glass wafer by spin coating, they were heated at 100 °C for 2 minutes using a hot plate, and then heated at 200 °C for 5 minutes. For the film with a thickness of 0.65 μm thus formed, the transmittance of light with a wavelength of 470 to 520 nm was measured, and the value of the wavelength at which the transmittance becomes 50% was recorded in the column of "Transmittance 50% Wavelength (nm)" in the following table.

[0232] As shown in the above table, the coloring compositions of the examples were able to form films with excellent long-term reliability.

[0233] (Example 1001) A green coloring composition was spin-coated onto a silicon wafer so that the film thickness after film formation was 1.0 μm. Then, it was heated at 100 °C for 2 minutes using a hot plate. Next, using an i-line stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Inc.), it was exposed through a mask of a 2-μm square dot pattern with an exposure dose of 1000 mJ / cm 2 Then, paddle development was performed at 23 °C for 60 seconds using a 0.3 mass% aqueous solution of tetramethylammonium hydroxide (TMAH). Thereafter, rinsing was performed with a spin shower, and further washing was performed with pure water. Next, by heating at 200 °C for 5 minutes using a hot plate, the green coloring composition was patterned to form green pixels. Similarly, the red coloring composition and the blue coloring composition were patterned by the same process to sequentially form red pixels and blue pixels, thereby forming a color filter having green pixels, red pixels, and blue pixels. In this color filter, the green pixels were formed in a Bayer pattern, and red pixels and blue pixels were formed in an island pattern in adjacent regions. The obtained color filter was incorporated into a solid-state imaging device according to a known method. This solid-state imaging device had a suitable image recognition ability. Note that, as the green coloring composition, the coloring composition of Example 2 was used. As the red coloring composition, the coloring composition of Example 29 was used. The blue coloring composition will be described later.
