Description

[Technical field]

[0001] The present invention relates to a method for producing a compound, and to a colored resin composition, a color filter, a display device, and a solid-state imaging device each containing the compound. [Background technology]

[0002] Phthalocyanine compounds are known as colorants such as dyes and pigments, and for example, a phthalocyanine compound represented by the following formula (I-e16) is disclosed in Non-Patent Document 1. Non-Patent Document 1 describes that the phthalocyanine compound represented by the following formula (II-16) was reacted in the presence of 1,8-diazabicyclo[5.4.0]-7-undecene (DBU) to synthesize the phthalocyanine compound represented by the formula (I-e16) in a yield of 52%.

[0005] [Non-Patent Document 1] Dyes and Pigments 88 (2011) 187-194 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the method described in Non-Patent Document 1 has low reproducibility, and the present inventors have been unable to substantially obtain the target compound by the method, and have been unable to reproduce the yield described in Non-Patent Document 1. Therefore, an object of the present invention is to provide a new production method that can stably synthesize a specific phthalocyanine compound in a predetermined yield or higher.

[0007] In addition, color filters used in display devices such as liquid crystal display devices, electroluminescent display devices, and plasma displays, and solid-state imaging devices such as CCD and CMOS sensors are manufactured from colored resin compositions. In particular, it is known that CI Pigment Green 58 is used as a colorant in colored resin compositions for producing green colored filters (green filters) in color filters (Patent Document 1). However, when a color filter formed from a colored resin composition containing CI Pigment Green 58 is applied to a display device, for example, when used for a long time, unevenness may occur due to a difference in brightness between the periphery and center of the colored filter. Therefore, the object of the present invention is to provide a colored resin composition capable of forming a color filter that can suppress uneven brightness even after long-term use.

[0073] [Method for producing compound (I)] The method for producing compound (I) is preferably to react compounds represented by formulas (II-1) to (II-4) in the presence of a base and a compound represented by formula (III). Hereinafter, such a method may be referred to as the method of the present invention. [ka] [In formula (III), X M is a halogen atom, a hydroxyl group, or OR M R M represents a hydrocarbon group having 1 to 6 carbon atoms.] [ka] [In formulas (II-1) to (II-4), R 1 ~R 16 has the same meaning as above.]

[0074] The present inventors have investigated the reaction of compounds represented by formulae (II-1) to (II-4) (hereinafter, collectively referred to as phthalonitrile compound (II)) in the presence of a base as in the above-mentioned Non-Patent Document 1 in producing compound (I), but have found that the method is poor in reproducibility and the yield of the target compound (I) is low. In particular, when the above-mentioned aryloxy group (i) is present, the yield tends to decrease. The present inventors have found that, by reacting phthalonitrile compound (II) in the presence of a base and a compound represented by formula (III) (hereinafter, sometimes referred to as aluminum compound (III)), the target compound (I) can be stably obtained in a predetermined yield or higher, even when the compound has an aryloxy group (i).

[0075] In addition, normally, when a phthalonitrile compound is reacted in the presence of an aluminum compound (III), an aluminum phthalocyanine having an aluminum atom as a central metal is preferentially obtained. However, when a phthalonitrile compound (II) having the above-mentioned aryloxy group (i) is reacted, unexpectedly, a metal-free phthalocyanine compound (I) is preferentially produced rather than an aluminum phthalocyanine represented by the following formula (IV) (hereinafter, sometimes referred to as aluminum phthalocyanine (IV) or compound (IV)), that is, the selectivity of the target compound (I) was good. Therefore, by adopting the production method of the present invention, the yield of the target compound (I) can be increased. In addition, by adopting the production method of the present invention, it is also preferable that the compound (I) can be produced in a short time.

[0076] [ka] [In formula (IV), R 1 ~R 16 and X M has the same meaning as above.]

[0077] The production method of the present invention will be described in detail below.

[0078] In formula (III), X M Examples of the halogen atom represented by the formula (I) include a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, etc., and among these, a chlorine atom is preferred.

Among these, an alkoxy group having 1 to 6 carbon atoms is preferred, and an alkoxy group having 1 to 4 carbon atoms is more preferred.

[0080] In formula (III), X M is preferably a halogen atom, a hydroxy group, or an alkoxy group having 1 to 4 carbon atoms, more preferably a chlorine atom or a hydroxy group, and particularly preferably a chlorine atom.

[0082] The amount of the aluminum compound (III) used is preferably 0.25 to 0.40 moles, more preferably 0.27 to 0.34 moles, per mole of the total amount of the phthalonitrile compound (II). By adjusting the amount of the aluminum compound (III) relative to the phthalonitrile compound (II) to a predetermined value or more, the yield of the compound (I) can be increased and the reaction time can be shortened. In addition, by adjusting the amount of the aluminum compound (III) relative to the phthalonitrile compound (II) to a predetermined value or less, the compound (I) is more likely to be preferentially produced than the aluminum phthalocyanine (IV), that is, the selectivity of the compound (I) is more improved.

[0083] As the base, an inorganic base and / or an organic base can be used. Examples of inorganic bases include alkali metal carbonates such as sodium carbonate and potassium carbonate; alkali metal phosphates such as trisodium phosphate and tripotassium phosphate; alkali metal hydroxides such as sodium hydroxide, potassium hydroxide, and lithium hydroxide; and the like. Examples of the organic base include trialkylamines such as triethylamine and N,N-diisopropylethylamine; nitrogen-containing heterocyclic compounds such as pyridine, picoline, 1,8-diazabicyclo[5.4.0]-7-undecene (DBU), and 1,5-diazabicyclo[4.3.0]non-5-ene (DBN); and the like. Among these, organic bases are preferred, nitrogen-containing heterocyclic compounds are more preferred, and 1,8-diazabicyclo[5.4.0]-7-undecene is even more preferred.

[0084] The amount of the base used is preferably 1.0 to 5.0 mol, more preferably 1.3 to 2.0 mol, per mol of the total amount of the phthalonitrile compound (II).

[0085] The reaction of the phthalonitrile compound (II) may be carried out in the presence of a solvent or in the absence of a solvent, but is preferably carried out in the presence of a solvent from the viewpoint of improving the reaction efficiency.

[0087] Among these, from the viewpoint of further improving the reaction efficiency, the solvent is preferably an alcohol solvent, more preferably a polyhydric alcohol solvent such as ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, or glycerin, and particularly preferably a polyhydric alcohol solvent having a boiling point of 160° C. or higher (preferably 200° C. or higher).

[0088] The amount of the solvent used is not particularly limited, but is, for example, 1 to 500 parts by mass, preferably 3 to 100 parts by mass, and more preferably 5 to 50 parts by mass, per part by mass of the total amount of the phthalonitrile compound (II).

[0089] The reaction temperature is, for example, 50°C to 200°C, preferably 90°C to 180°C, and more preferably 120°C to 160°C.

[0090] In the production method of the present invention, since the reaction is carried out in the presence of the aluminum compound (III), the yield of the compound (I) can be increased even if the reaction time is short. From the viewpoint of productivity, the reaction time is preferably 30 minutes to 50 hours, more preferably 1 to 40 hours, and further preferably 3 to 35 hours, and can also be 20 hours or less, or 15 hours or less.

[0091] The reaction mixture obtained by the above reaction contains the target compound (I). In the production method of the present invention, in which the reaction is carried out in the presence of the aluminum compound (III), the above aluminum phthalocyanine (IV) may be generated as a by-product, but since the synthesis uses the phthalonitrile compound (II) having at least one aryloxy group (i), the compound (I) is synthesized preferentially over the aluminum phthalocyanine (IV). Therefore, in the production method of the present invention, the amount of compound (I) obtained is preferably 1.5 mol or more, more preferably 2.0 mol or more, and can also be 3.0 mol or more, or 4.0 mol or more, per mol of aluminum phthalocyanine (IV). The amount of compound (I) relative to aluminum phthalocyanine (IV) can be calculated by isolating compound (I) and aluminum phthalocyanine (IV) from the reaction mixture and measuring the yield.

[0092] The method for isolating compound (I) and aluminum phthalocyanine (IV) from the reaction mixture is not particularly limited, and various known methods can be used. For example, compound (I) can be precipitated by cooling the reaction mixture to room temperature (e.g., 18 to 24°C) and adding water or ethyl acetate as necessary. At this time, if aluminum phthalocyanine (IV) is contained in the reaction mixture, aluminum phthalocyanine (IV) also precipitates together with compound (I). Thereafter, the precipitate is washed with water, acetone, methanol, etc. as necessary, and then purified by, for example, column chromatography, etc., to isolate compound (I) and aluminum phthalocyanine (IV).

[0093] The column chromatography is preferably a silica gel column chromatography. The mobile phase (developing solvent) used in the column chromatography is not particularly limited and may be appropriately selected depending on the compound to be isolated, but it is preferable to use an aromatic hydrocarbon solvent and an ether solvent, and it is more preferable to use a gradient method in which extraction is performed while changing the aromatic hydrocarbon solvent:ether solvent (mass ratio) from 100:0 to 0:100.

[0094] Examples of the aromatic hydrocarbon solvent include benzene, toluene, xylene, and mesitylene, and among these, toluene is preferred. The ether solvent may be any of those described above as the ether solvent used in the reaction of the phthalonitrile compound (II), and among these, tetrahydrofuran is preferred.

[0095] By employing the production method of the present invention, the yield of compound (I) from phthalonitrile compound (II) can be increased. The yield of compound (I) in the reaction for synthesizing compound (I) from phthalonitrile compound (II) is preferably 5% or more, more preferably 15% or more, further preferably 20% or more, and can be 30% or more or 40% or more.

[0096] The content of compound (I) in the total amount of colorant (A) is, for example, 20 to 100 mass%, preferably 30 to 100 mass%, more preferably 40 to 90 mass%, and further preferably 50 to 80 mass%. When the content of compound (I) in colorant (A) is within the above range, it becomes easier to obtain the desired spectrum, and also easier to suppress unevenness in brightness after long-term use.

[0097] The colorant (A) may further contain a colorant (hereinafter, may be referred to as colorant (A1)) different from the compound (I). The colorant (A1) may be either a dye or a pigment, but is preferably a pigment from the viewpoint of further suppressing unevenness in brightness after long-term use.

[0098] Examples of dyes include compounds classified as having a hue other than pigments in the Color Index (published by The Society of Dyers and Colourists) and known dyes described in Dyeing Notes (Shikisensha).

[0099] Examples of dyes include azo dyes, cyanine dyes, triphenylmethane dyes, xanthene dyes, thiazole dyes, oxazine dyes, quinophthalone dyes, anthraquinone dyes, naphthoquinone dyes, quinoneimine dyes, methine dyes, azomethine dyes, squarylium dyes, acridine dyes, styryl dyes, coumarin dyes, quinoline dyes, nitro dyes, and phthalocyanine dyes.

[0127] In the resin [K1], the ratio of structural units derived from each of them is as follows among all structural units constituting the resin [K1]: Structural units derived from (a): 2 to 60 mol% Structural units derived from (b): 40 to 98 mol% It is preferred that Structural units derived from (a): 10 to 50 mol% Structural units derived from (b): 50 to 90 mol% It is more preferable that: When the ratio of the structural units of the resin [K1] is within the above range, the storage stability of the colored resin composition, the developability when forming a colored pattern, and the solvent resistance of the obtained color filter tend to be superior.

[0128] Resin [K1] can be produced, for example, by referring to the method described in the literature "Experimental Methods of Polymer Synthesis" (written by Takayuki Otsu, published by Kagaku Dojin Co., Ltd., 1st edition, 1st printing, published on March 1, 1972) and the cited references described in said literature.

[0129] Specifically, a method is exemplified in which predetermined amounts of (a) and (b), a polymerization initiator, a solvent, etc. are placed in a reaction vessel, and the atmosphere is deoxygenated by, for example, replacing oxygen with nitrogen, and the mixture is heated and kept warm while stirring. The polymerization initiator and solvent used here are not particularly limited, and those commonly used in the relevant field can be used. For example, examples of the polymerization initiator include azo compounds (2,2'-azobisisobutyronitrile, 2,2'-azobis(2,4-dimethylvaleronitrile), etc.) and organic peroxides (benzoyl peroxide, etc.), and examples of the solvent include those that dissolve each monomer, such as the solvent (E) described below.

[0130] The obtained copolymer may be used as it is after the reaction, or may be used after concentration or dilution, or may be used after extraction as a solid (powder) by a method such as reprecipitation. In particular, by using the solvent contained in the colored resin composition as the solvent during this polymerization, the solution after the reaction can be used as it is for the preparation of the colored resin composition, and therefore the manufacturing process of the colored resin composition can be simplified.

[0131] In the resin [K2], the ratio of structural units derived from each of them is as follows among all structural units constituting the resin [K2]: Structural units derived from (a): 2 to 45 mol% Structural units derived from (b): 2 to 95 mol% Structural units derived from (c): 1 to 65 mol% It is preferred that Structural units derived from (a): 5 to 40 mol% Structural units derived from (b): 5 to 80 mol% Structural units derived from (c): 5 to 60 mol% It is more preferable that: When the ratio of the structural units of the resin [K2] is within the above range, the storage stability of the colored resin composition, the developability when forming a colored pattern, and the solvent resistance, heat resistance, and mechanical strength of the resulting color filter tend to be superior.

[0132] Resin [K2] can be produced, for example, in the same manner as described above as the method for producing resin [K1].

[0133] In the resin [K3], the ratio of structural units derived from each of them is as follows among all structural units constituting the resin [K3]: Structural units derived from (a): 2 to 60 mol% Structural units derived from (c): 40 to 98 mol% It is preferred that Structural units derived from (a): 10 to 50 mol% Structural units derived from (c): 50 to 90 mol% It is more preferable that: Resin [K3] can be produced, for example, in the same manner as described above as the method for producing resin [K1].

[0134] Resin [K4] can be produced by obtaining a copolymer of (a) and (c), and then adding the cyclic ether having 2 to 4 carbon atoms contained in (b) to the carboxylic acid and / or carboxylic acid anhydride contained in (a). First, a copolymer of (a) and (c) is produced in the same manner as described for the production method of resin [K1]. In this case, the ratio of the structural units derived from each is preferably the same as that described for resin [K3].

[0135] Next, a part of the carboxylic acid and / or carboxylic acid anhydride derived from (a) in the copolymer is reacted with a cyclic ether having 2 to 4 carbon atoms contained in (b). Following the production of the copolymer of (a) and (c), the atmosphere in the flask is replaced with air from nitrogen, and (b), a reaction catalyst for the reaction of a carboxylic acid or a carboxylic acid anhydride with a cyclic ether (e.g., tris(dimethylaminomethyl)phenol, etc.), a polymerization inhibitor (e.g., hydroquinone, etc.), etc. are placed in the flask, and the mixture is reacted, for example, at 60 to 130°C for 1 to 10 hours to produce the resin [K4]. The amount of (b) used is preferably 5 to 80 moles, more preferably 10 to 75 moles, relative to 100 moles of (a). By adjusting the amount within this range, the storage stability of the colored resin composition, the developability when forming a pattern, and the balance of the solvent resistance, heat resistance, mechanical strength, and sensitivity of the resulting pattern tend to be good. Since the reactivity of the cyclic ether is high and unreacted (b) is unlikely to remain, (b1) is preferable as (b) used in the resin [K4], and (b1-1) is more preferable. The amount of the reaction catalyst used is preferably 0.001 to 5 parts by mass per 100 parts by mass of the total amount of (a), (b) and (c).The amount of the polymerization inhibitor used is preferably 0.001 to 5 parts by mass per 100 parts by mass of the total amount of (a), (b) and (c). The reaction conditions such as the charging method, reaction temperature and time can be appropriately adjusted in consideration of the production equipment, the amount of heat generated by the polymerization, etc. As with the polymerization conditions, the charging method and reaction temperature can be appropriately adjusted in consideration of the production equipment, the amount of heat generated by the polymerization, etc.

[0136] Resin [K5] is produced in the first step by the same method as the above-mentioned resin [K1] to obtain a copolymer of (b) and (c). As in the above, the obtained copolymer may be used as it is in the form of a solution after the reaction, or may be a concentrated or diluted solution, or may be extracted as a solid (powder) by a method such as reprecipitation. The ratios of the structural units derived from (b) and (c) to the total number of moles of all structural units constituting the copolymer are, respectively, Structural units derived from (b): 5 to 95 mol% Structural units derived from (c): 5 to 95 mol% It is preferred that Structural units derived from (b): 10 to 90 mol% Structural units derived from (c): 10 to 90 mol% It is more preferable that:

[0137] Furthermore, under the same conditions as in the manufacturing method of resin [K4], resin [K5] can be obtained by reacting the cyclic ether derived from (b) contained in the copolymer of (b) and (c) with the carboxylic acid or carboxylic anhydride contained in (a). The amount of (a) reacted with the copolymer is preferably 5 to 100 moles per 100 moles of (b). Because the reactivity of cyclic ethers is high and unreacted (b) is unlikely to remain, (b1) is preferred as (b) used in resin [K5], and (b1-1) is more preferred.

[0138] Resin [K6] is a resin obtained by further reacting resin [K5] with a carboxylic acid anhydride. The hydroxyl group generated by the reaction of a cyclic ether with a carboxylic acid or a carboxylic acid anhydride is reacted with the carboxylic acid anhydride. Examples of the carboxylic acid anhydride include succinic anhydride, maleic anhydride, citraconic anhydride, itaconic anhydride, 3-vinylphthalic anhydride, 4-vinylphthalic anhydride, 3,4,5,6-tetrahydrophthalic anhydride, 1,2,3,6-tetrahydrophthalic anhydride, dimethyltetrahydrophthalic anhydride, 5,6-dicarboxybicyclo[2.2.1]hept-2-ene anhydride, etc. The amount of the carboxylic acid anhydride used is preferably 0.1 to 1 mole per mole of the amount of (a) used.

The content of the resin (B) is, for example, 30 to 200 parts by mass, preferably 50 to 180 parts by mass, and more preferably 80 to 150 parts by mass, relative to 100 parts by mass of the compound (I).

[0191] When the colorant (A) contains a dye, the dye may be dissolved in advance in a part or whole of the solvent (E) to prepare a solution. The solution is preferably filtered through a filter having a pore size of about 0.01 to 1 μm.

[0192] [Color Filter] Examples of the method for producing a colored pattern of a color filter from the colored resin composition of the present invention include a photolithography method, an inkjet method, and a printing method. Among them, the photolithography method is preferable. The photolithography method is a method in which the colored resin composition is applied to a substrate, dried to form a composition layer, and the composition layer is exposed through a photomask and developed. In the photolithography method, a colored coating film, which is a cured product of the composition layer, can be formed by not using a photomask during exposure and / or not developing.

[0193] The film thickness of the color filter (colored coating film or colored pattern) is, for example, 30 μm or less, preferably 20 μm or less, more preferably 6 μm or less, even more preferably 3 μm or less, even more preferably 1.5 μm or less, particularly preferably 0.5 μm or less, and is preferably 0.1 μm or more, more preferably 0.2 μm or more, and even more preferably 0.3 μm or more.

[0194] The substrate may be a glass plate such as quartz glass, borosilicate glass, alumina silicate glass, or soda lime glass with a silica-coated surface, a resin plate such as polycarbonate, polymethylmethacrylate, or polyethylene terephthalate, silicon, or a substrate having a thin film of aluminum, silver, or a silver / copper / palladium alloy formed thereon. On these substrates, another color filter layer, a resin layer, a transistor, a circuit, or the like may be formed. A silicon substrate having an HMDS treatment may also be used.

[0195] Formation of each color pixel (each color color filter) by photolithography can be performed with known or conventional equipment and conditions. For example, it can be produced as follows. First, a colored resin composition is applied onto a substrate, and volatile components such as a solvent are removed by heating and drying (pre-baking) and / or drying under reduced pressure to obtain a smooth composition layer. Examples of the application method include spin coating, slit coating, and slit and spin coating. The temperature when drying by heating is preferably 30 to 120°C, more preferably 50 to 110°C. The heating time is preferably 10 seconds to 60 minutes, more preferably 30 seconds to 30 minutes. When drying under reduced pressure, it is preferably performed under a pressure of 50 to 150 Pa at a temperature range of 20 to 25°C. The film thickness of the composition layer is not particularly limited and may be appropriately selected according to the film thickness of the desired color filter.

[0196] Next, the composition layer is exposed through a photomask for forming a desired colored pattern. The pattern on the photomask is not particularly limited, and a pattern according to the intended use is used. As the light source used for exposure, a light source that generates light with a wavelength of 250 to 450 nm is preferable. For example, light less than 250 nm may be cut using a filter that cuts this wavelength range, or light near 436 nm, near 408 nm, and near 365 nm may be selectively extracted using a bandpass filter that extracts these wavelength ranges. Specific examples include mercury lamps, light-emitting diodes, metal halide lamps, and halogen lamps. It is preferable to use a reduced projection exposure device or a proximity exposure device such as a mask aligner and a stepper, since it is possible to uniformly irradiate the entire exposure surface with parallel light rays and to accurately align the photomask and the substrate.

[0197] The composition layer after exposure is brought into contact with a developer for development, thereby forming a colored pattern on the substrate. The unexposed portion of the composition layer is dissolved in the developer and removed by development. The developer is preferably an aqueous solution of an alkaline compound such as potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, or tetramethylammonium hydroxide. The concentration of these alkaline compounds in the aqueous solution is preferably 0.01 to 10% by mass, more preferably 0.03 to 5% by mass. Furthermore, the developer may contain a surfactant. The development method may be any of a paddle method, a dipping method, and a spray method. Furthermore, the substrate may be tilted at any angle during development. After development, it is preferable to wash with water.

[0198] Furthermore, it is preferable to perform post-baking on the obtained colored pattern. The post-baking temperature is preferably 80 to 250° C., more preferably 100 to 245° C. The post-baking time is preferably 1 to 120 minutes, more preferably 2 to 30 minutes.

[0199] The colored pattern and colored coating film thus obtained are useful as color filters, and the color filters are useful as color filters for use in display devices (e.g., liquid crystal display devices, organic EL devices, etc.), electronic paper, solid-state imaging devices, etc.

[0200] In particular, the colored pattern and colored coating film are useful as a green filter in a color filter. When the colored pattern or colored coating film has a film thickness of 2.0 μm, it is preferable that the colored pattern or colored coating film satisfies the following (i) and (ii). A colored resin composition capable of forming a colored pattern or colored coating film that satisfies the following (i) and (ii) can form a green filter with excellent spectral characteristics. In particular, from the viewpoint of being able to exhibit good spectral characteristics even after long-term use, it is preferable that the colored pattern and colored coating film satisfy the following (i) and (ii) even after the light irradiation test described in the Examples section below. (i) Transmittance at 550 nm is 35% or more and 99% or less (ii) Transmittance at 620 nm is 0.1% or more and 30% or less (preferably 0.1 to 20%) EXAMPLES

[0329] <Examples B1 to B9 and Comparative Examples B1 to B4> (Preparation of colored patterns) Each of the colored resin compositions E1 to E5 and C1 to C2 was applied by spin coating onto a 5 cm square glass substrate (Eagle 2000; Corning Incorporated), and then prebaked at 100°C for 3 minutes to form a colored composition layer. After cooling, the substrate was exposed to light at 100 mJ / cm2 in the air without using a photomask using an exposure machine (TME-150RSK; Topcon Corporation). 2 The colored composition layer after the light irradiation was post-baked in an oven at 230° C. for 20 minutes to obtain a colored coating film. After cooling, the thickness of the obtained colored coating film was measured using a thickness measuring device (DEKTAK3; manufactured by Nippon Shinku Gijutsu Co., Ltd.), and the thickness of the obtained colored coating film was the same 2.0 μm in all Examples and Comparative Examples.

[0330] <Evaluation> (1) Measurement of initial brightness The resulting colored coating film was measured for spectroscopy using a colorimeter (OSP-SP-200; manufactured by Olympus Corporation), and the xy chromaticity coordinates (x, y) and stimulus value Y in the CIE XYZ color system were measured using the characteristic function of Illuminant C. A larger Y value indicates a higher lightness.

[0331] (2) Evaluation of brightness unevenness suppression An ultraviolet cut filter (COLORED OPTICAL GLASS L38; manufactured by HOYA Corporation; cuts light of 380 nm or less) was placed on the obtained colored coating film, and a light irradiation test was performed by irradiating the xenon lamp light for 48 or 120 hours (irradiation time is shown in Table 8) using a light resistance tester (Suntest CPS+: manufactured by Toyo Seiki Seisakusho Co., Ltd.). The relative value (%) of the irritation value Y after the light irradiation test, when the irritation value Y (initial luminosity obtained in (1) above) before the light irradiation test was taken as 100%, was calculated as the "luminosity change rate" and evaluated according to the following evaluation criteria. The results are shown in Table 8. When the luminosity change rate is 98.0% or more under these measurement conditions, the luminosity difference between the periphery and the center of the colored filter after long-term use becomes difficult for the human eye to distinguish, and it can be said that the color filter has sufficient performance. Brightness unevenness suppression ◎: Brightness change rate is 99.0% or more Suppression of uneven brightness: Brightness change rate is 98.0% or more and less than 99.0% Suppression of uneven brightness: Brightness change rate is less than 98.0%

[0332] [Table 8]

[0333] (3) Green spectral characteristics evaluation The colored coating film after the light irradiation test in "(2) Evaluation of brightness unevenness suppression" was subjected to spectrum measurement using an ultraviolet, visible, near infrared absorption spectrometer (JASCO: V-770) to evaluate the transmittance in the green region when the colored coating film had a thickness of 2.0 μm. The results are shown in Table 9. If the transmittance at 550 nm is 35% or more and 99% or less, and the transmittance at 620 nm is 0.1% or more and 30% or less, it can be said that the green filter in a color filter can exhibit better spectral characteristics even after long-term use.
