[0097] In the resin [K1], the ratio of the structural units derived from each of these is as follows: Structural units derived from (a): 2 to 60 mol% Structural units derived from (b): 40 to 98 mol% Preferably, 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 colored resin composition tends to have excellent storage stability, developability when forming a colored pattern, and solvent resistance of the resulting optical filter.

[0098] Resin [K1] can be produced, for example, by 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 March 1, 1972) and by reference to the references described in said literature.

[0099] Specifically, a method can be exemplified in which predetermined amounts of (a) and (b), a polymerization initiator, a solvent, and the like are placed in a reaction vessel, and the atmosphere is deoxygenated, for example by replacing oxygen with nitrogen, followed by heating and keeping the temperature while stirring. The polymerization initiator, solvent, and the like used here are not particularly limited, and those commonly used in the relevant field can be used. For example, polymerization initiators include azo compounds (2,2'-azobisisobutyronitrile, 2,2'-azobis(2,4-dimethylvaleronitrile), etc.) and organic peroxides (benzoyl peroxide, etc.), and the solvent can be any solvent that dissolves each monomer, such as the solvent (E) described below.

[0100] The obtained copolymer may be used as a solution after the reaction as it is, or may be used as a concentrated or diluted solution, or may be used as a solid (powder) extracted by a method such as reprecipitation. In particular, by using the solvent contained in the colored resin composition as a solvent during this polymerization, the solution after the reaction can be used as it is for preparing the colored resin composition, which simplifies the production process of the colored resin composition.

[0101] In the resin [K2], the ratio of the structural units derived from each of these is as follows: 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% Preferably, 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 colored resin composition tends to have excellent storage stability, developability when forming a colored pattern, and solvent resistance, heat resistance, and mechanical strength of the resulting optical filter.

[0102] Resin [K2] can be produced, for example, in the same manner as described above for producing resin [K1].

[0103] In the resin [K3], the ratio of the structural units derived from each of these is as follows: Structural units derived from (a): 2 to 60 mol% Structural units derived from (c): 40 to 98 mol% Preferably, 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 for producing resin [K1].

[0104] 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 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].

[0105] 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 mol, more preferably 10 to 75 mol, per 100 mol of (a). By using 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. Because the reactivity of cyclic ethers is high and unreacted (b) is unlikely to remain, (b1) is preferred as (b) used in resin [K4], and (b1-1) is more preferred. The amount of the reaction catalyst used is preferably 0.001 to 5 parts by mass per 100 parts by mass of the total 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 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.

[0106] Resin [K5] is obtained in the first step by the same method as in the production of resin [K1] described above, to obtain a copolymer of (b) and (c). As in the above, the obtained copolymer may be used as a solution after the reaction as is, a concentrated or diluted solution, or a solid (powder) obtained 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 as follows: Structural units derived from (b): 5 to 95 mol% Structural units derived from (c): 5 to 95 mol% Preferably, Structural units derived from (b): 10 to 90 mol% Structural units derived from (c): 10 to 90 mol% It is more preferable that:

[0107] Furthermore, under the same conditions as in the production 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) used to react with the copolymer is preferably 5 to 80 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.

[0108] Resin [K6] is a resin obtained by further reacting resin [K5] with a carboxylic acid anhydride.

The colored resin composition after mixing is preferably filtered through a filter with a pore size of about 0.01 to 10 μm.

[0156] [Color Filter] Methods for producing a colored pattern of a color filter from the colored resin composition of the present invention include photolithography, inkjet printing, and printing. Among these, photolithography is preferred. The photolithography is a method in which the colored resin composition is applied to a substrate, dried to form a composition layer, and then exposed to light through a photomask and developed. In the photolithography, 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.

[0157] The film thickness of the color filter (cured film) 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, still more preferably 1.5 μm or less, particularly preferably 0.5 μm or less, and preferably 0.1 μm or more, more preferably 0.2 μm or more, and even more preferably 0.3 μm or more.

[0158] The substrate may be a glass plate such as quartz glass, borosilicate glass, alumina silicate glass, or silica-coated soda lime glass; a resin plate such as polycarbonate, polymethyl methacrylate, or polyethylene terephthalate; silicon; or a substrate having a thin film of aluminum, silver, or a silver / copper / palladium alloy formed thereon. A separate color filter layer, a resin layer, a transistor, a circuit, or the like may be formed on these substrates. Alternatively, a silicon substrate treated with HMDS may be used.

[0159] Formation of each color pixel by photolithography can be carried out using known or conventional equipment and conditions. For example, it can be produced as follows. First, a colored resin composition is applied to a substrate, and then the composition is dried by heating and drying (pre-baking) and / or drying under reduced pressure to remove volatile components such as solvents and obtain a smooth composition layer. Examples of application methods include spin coating, slit coating, and slit and spin coating. When drying by heating, the temperature 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 carried out under a pressure of 50 to 150 Pa and at a temperature of 20 to 25°C. The film thickness of the composition layer is not particularly limited and may be appropriately selected depending on the film thickness of the desired color filter.

[0160] Next, the composition layer is exposed through a photomask to form a desired color pattern. The pattern on the photomask is not particularly limited, and a pattern appropriate for the intended application is used. The light source used for exposure is preferably a light source that emits light with a wavelength of 250 to 450 nm. For example, light less than 350 nm may be cut using a filter that cuts this wavelength range, or light around 436 nm, 408 nm, and 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 reduction projection exposure device or proximity exposure device such as a mask aligner or stepper, as this allows for uniform irradiation of the entire exposure surface with parallel light and allows for accurate alignment of the photomask and substrate.

[0161] A colored pattern is formed on the substrate by bringing the exposed composition layer into contact with a developer and developing it. The unexposed portions of the composition layer are dissolved and removed by development. The developer is preferably an aqueous solution of an alkaline compound such as potassium hydroxide, sodium bicarbonate, 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. The developer may also contain a surfactant. The development method may be any of a puddle method, a dipping method, a spray method, or the like. Furthermore, the substrate may be tilted at any angle during development. After development, it is preferable to wash with water.

[0162] Furthermore, it is preferable to post-bake the obtained colored pattern. The post-bake temperature is preferably 80 to 250° C., more preferably 100 to 245° C. The post-bake time is preferably 1 to 120 minutes, more preferably 2 to 30 minutes.

[0163] The colored patterns and colored coating films thus obtained are useful as color filters, and the color filters are useful as color filters used in display devices (e.g., liquid crystal display devices, organic EL devices, etc.), electronic paper, solid-state imaging devices, etc.

[0178] [Formation of colored coating film] The colored resin compositions prepared using the colored resin composition 1 and the comparative colored resin composition 1 were applied by spin coating onto a 5 cm square glass substrate (Eagle 2000; manufactured by Corning Incorporated), and then pre-baked at 100 ° C. for 3 minutes to obtain a colored coating film.

[0179] [Color change of colored coating before and after post-baking] The prebaked colored coating film was subjected to spectral measurement 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. The transmittance of the prebaked colored coating film was also measured. Thereafter, the prebaked colored coating film was postbaked at 230° C. for 10 minutes. The xy chromaticity coordinates (x, y) and stimulus value Y of the colored coating film after post-baking were measured using the same method as above. The color difference ΔEab was calculated from the measurements before and after post-baking. The smaller ΔEab means the smaller the color change. The results are shown in Table 11. The transmittance of the colored coating film after post-baking was measured. The transmittance at a certain wavelength λ before post-baking was defined as X λ , the transmittance after post-baking is Y λ When the magnitude of the change in transmittance is |(1-Y λ / X λ )×100|(%) was calculated at 5 nm intervals from 500 nm to 650 nm, and the average of the obtained values ​​was taken as the "rate of change in transmittance from 500 nm to 650 nm." The results are shown in Table 11.
