More preferably, the ratio is 10 to 50 mol% for the structural unit derived from (a) and 50 to 90 mol% for the structural unit derived from (b). When the ratio of the structural units of the resin [K1] is within the above range, the storage stability of the colored composition, the developability when forming a colored pattern, and the solvent resistance of the obtained color filter tend to be excellent. Resin [K1] can be produced, for example, by referring to the method described in the document "Experimental Methods for Polymer Synthesis" (written by Takayuki Otsu, Kagaku Doujin Publishing Co., Ltd., 1st edition, 1st printing, published on March 1, 1972) and the cited documents described in the document. Specifically, a method can be used in which predetermined amounts of (a) and (b), a polymerization initiator, and a solvent are placed in a reaction vessel, oxygen is replaced with nitrogen, for example, to create a deoxygenated atmosphere, and the mixture is heated and maintained while stirring. The polymerization initiator and solvent used herein are not particularly limited, and those commonly used in this field can be used. For example, polymerization initiators include azo compounds (such as 2,2'-azobisisobutyronitrile and 2,2'-azobis(2,4-dimethylvaleronitrile)) or organic peroxides (such as benzoyl peroxide). Solvents can be any solvent that dissolves the monomers, and examples include the solvents described below as the solvent (E) for the coloring composition of the present invention. Furthermore, the copolymer obtained may be used directly as the post-reaction solution, as a concentrated or diluted solution, or as a solid (powder) obtained by reprecipitation or other methods. In particular, by using the solvent contained in the coloring composition of the present invention as the solvent during the polymerization, the post-reaction solution can be used directly in the preparation of the coloring composition of the present invention, thereby simplifying the production process of the coloring composition of the present invention. Among all the structural units constituting the resin [K2], the ratio of the structural units derived from each of the structural units in the resin [K2] is preferably 2 to 45 mol% for the structural unit derived from (a), 2 to 95 mol% for the structural unit derived from (b), and 1 to 75 mol% for the structural unit derived from (c). More preferably, the ratio is 5 to 40 mol% for the structural unit derived from (a), 5 to 80 mol% for the structural unit derived from (b), and 5 to 70 mol% for the structural unit derived from (c). When the ratio of the structural units of the resin [K2] is within the above range, the storage stability of the colored composition, the developability when forming a colored pattern, and the solvent resistance, heat resistance, and mechanical strength of the obtained color filter tend to be excellent. The resin [K2] can be produced, for example, in the same manner as described as the method for producing the resin [K1]. Among all the structural units constituting the resin [K3], the ratio of the structural units derived from each of the structural units in the resin [K3] is preferably 2 mol% to 60 mol% for the structural unit derived from (a) and 40 mol% to 98 mol% for the structural unit derived from (c). More preferably, the ratio is 10 mol% to 50 mol% for the structural unit derived from (a) and 50 mol% to 90 mol% for the structural unit derived from (c). The resin [K3] can be produced, for example, in the same manner as described as the method for producing the resin [K1]. Resin [K4] can be produced by obtaining a copolymer of (a) and (c), and then adding the C 2-4 cyclic ether contained in (b) to the carboxylic acid and / or carboxylic 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 listed for resin [K3]. Next, the cyclic ether having 2 to 4 carbon atoms contained in (b) is reacted with a portion of the carboxylic acid and / or carboxylic anhydride derived from (a) in the copolymer. Following the production of the copolymer of (a) and (c), the atmosphere in the flask is replaced from nitrogen to air. (b), a reaction catalyst for the carboxylic acid or carboxylic anhydride and the cyclic ether (e.g., tris(dimethylaminomethyl)phenol), and a polymerization inhibitor (e.g., hydroquinone) are placed in the flask and reacted at, for example, 60°C to 130°C for 1 to 10 hours to produce resin [K4]. The amount of (b) used is preferably 5 to 80 mol, more preferably 10 to 75 mol, per 100 mol of (a). This range tends to improve the balance between the storage stability of the colored composition, the developability during pattern formation, and the solvent resistance, heat resistance, mechanical strength, and sensitivity of the resulting pattern. Because cyclic ethers are highly reactive and unreacted (b) is less likely to remain, (b1) and more preferably (b1-1) are used as (b) in resin [K4]. 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). Reaction conditions such as the addition method, reaction temperature, and time can be appropriately adjusted based on factors such as the production equipment and the amount of heat generated by polymerization. Similarly to the polymerization conditions, the addition method and reaction temperature can be appropriately adjusted based on factors such as the production equipment and the amount of heat generated by polymerization. Regarding resin [K5], as a first step, a copolymer of (b) and (c) is obtained in the same manner as for the production method of resin [K1]. As described above, the obtained copolymer may be used as the solution after the reaction, as a concentrated or diluted solution, or as a solid (powder) obtained by methods such as reprecipitation. The ratios of the structural units derived from (b) and (c) relative to the total molar number of all structural units constituting the copolymer are preferably 5 to 95 mol% for structural units derived from (b) and 5 to 95 mol% for structural units derived from (c). More preferably, the ratios are 10 to 90 mol% for structural units derived from (b) and 10 to 90 mol% for structural units derived from (c). Furthermore, resin [K5] can be obtained by reacting the carboxylic acid or carboxylic anhydride contained in (a) with the cyclic ether derived from (b) contained in the copolymer of (b) and (c) under the same conditions as those for producing resin [K4]. The amount of (a) reacted with the copolymer is preferably 5 to 80 mol per 100 mol of (b). Because cyclic ethers have high reactivity and are less likely to leave unreacted (b), (b1) and more preferably (b1-1) are used as (b) in resin [K5]. Resin [K6] is obtained by further reacting carboxylic anhydride with resin [K5]. The carboxylic anhydride reacts with the hydroxyl groups generated by the reaction of a cyclic ether with a carboxylic acid or a carboxylic anhydride. Examples of carboxylic anhydrides include 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, and 5,6-dicarboxybicyclo[2.2.1]hept-2-ene anhydride.

Other Components The coloring composition of the present invention may also contain fillers, other polymer compounds, adhesion promoters, antioxidants, light stabilizers, chain transfer agents, and other additives known in the art, as needed. <Method for Producing Coloring Composition> The coloring composition of the present invention can be prepared, for example, by mixing a coloring agent (A) comprising compound (I), and optionally, a resin (B), a polymerizable compound (C), a polymerization initiator (D), a polymerization initiation aid (D1), a solvent (E), a leveling agent (F), and other components. Mixing can be performed using known or customary equipment and conditions. The colorant (A) can be used by premixing with part or all of the solvent (E) and dispersing it using a bead mill or the like until its average particle size is approximately 0.2 μm or less. At this point, part or all of the dispersant and resin (B) may be added as needed. The desired colored composition is preferably prepared by mixing the remaining components into the dispersion thus obtained to achieve a desired concentration. When using a bead mill, the beads preferably have a diameter of 0.05 mm to 0.5 mm, and materials such as glass, ceramic, and metal may be used. <Method for Manufacturing Color Filters> Examples of methods for manufacturing the coloring pattern of a color filter using the coloring composition of the present invention include photolithography, inkjet printing, and printing. Among these, photolithography is preferred. Photolithography involves applying the coloring composition to a substrate, drying it to form a composition layer, and then exposing and developing the composition layer through a photomask to form a coloring pattern. In photolithography, by not using a photomask and / or not performing development during exposure, a colored coating film can be formed as a cured product of the composition layer. The colored pattern or colored coating film thus formed constitutes the color filter of the present invention. The thickness of the color filter is not particularly limited and can be appropriately adjusted depending on the purpose and application. For example, it is 0.1 μm to 30 μm, preferably 0.1 μm to 20 μm, and more preferably 0.5 μm to 6 μm. Substrates can be made from glass plates such as quartz glass, borosilicate glass, aluminosilicate glass, or soda-lime glass coated with silicon dioxide; or resin plates such as polycarbonate, polymethyl methacrylate, and polyethylene terephthalate; or silicon; or substrates with thin films of aluminum, silver, or silver / copper / palladium alloys formed on these substrates. Other color filter layers, resin layers, transistors, and circuits can also be formed on these substrates. Alternatively, a silicon substrate treated with hexamethyldisilazane (HMDS) can be used. The formation of pixels of various colors using photolithography can be performed using known or customary devices or conditions. For example, it can be produced as follows. First, a colored composition is applied to a substrate and dried by removing volatile components such as solvents by heat drying (prebaking) and / or reduced pressure drying to obtain a smooth composition layer. Examples of coating methods include spin coating, slit coating, and slit and spin coating. The temperature during heat drying is preferably 30°C or higher and 120°C or lower, more preferably 50°C or higher and 110°C or lower. In addition, the heating time is preferably 10 seconds or higher and 60 minutes or lower, more preferably 30 seconds or higher and 30 minutes or lower. When reduced pressure drying is performed, it is preferably performed at a pressure of 50 Pa to 150 Pa and a temperature range of 20°C to 25°C. The film thickness of the composition layer is not particularly limited and can be appropriately selected according to the film thickness of the target color filter. Secondly, the composition layer can be exposed through a photomask used to form a target coloring pattern. The pattern on the photomask is not particularly limited, and a pattern corresponding to the target application can be used. As the light source used in the exposure, a light source that generates light with a wavelength of 250 nm to 450 nm is preferably used. For example, for light less than 250 nm, a filter that cuts off this wavelength range can be used to cut off the light, or for light near 436 nm, near 408 nm, and near 365 nm, a bandpass filter that extracts these wavelength ranges can be used to selectively extract the light. Specifically, mercury lamps, light-emitting diodes, metal halide lamps, halogen lamps, etc. can be listed. In order to evenly irradiate the entire exposure surface with parallel light or to accurately align the photomask and the substrate, it is preferably to use a reduced projection exposure device or a proximity exposure device such as a mask aligner and a stepper. The exposed composition layer is brought into contact with a developer to perform development, thereby forming a colored pattern on the substrate. By development, the unexposed portion of the composition layer is dissolved in the developer and removed. As a developer, for example, aqueous solutions of alkaline compounds such as potassium hydroxide, sodium bicarbonate, sodium carbonate, and tetramethylammonium hydroxide are preferred. The concentration of these alkaline compounds in the aqueous solution is preferably 0.01% by mass or more and 10% by mass or less, more preferably 0.03% by mass or more and 5% by mass or less. Furthermore, the developer may also contain a surfactant. The development method may be any one of a coating method, an immersion method, and a spray method. Furthermore, the substrate may be tilted at an arbitrary angle during development. After development, it is preferably washed with water. Furthermore, the obtained colored pattern and colored coating film are preferably post-baked. The post-baking temperature is preferably 80°C to 250°C, more preferably 100°C to 245°C. The post-baking time is preferably 1 minute to 120 minutes, more preferably 2 minutes to 30 minutes. The colored pattern and colored coating film 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 electroluminescence (EL) devices, etc.), electronic paper, solid-state imaging devices, etc. [Examples] The present invention is described in more detail below with reference to the following examples, but the present invention is not limited to these examples.

After cooling, the layers were exposed to light at 60 mJ / cm² in an atmospheric environment through a mask with a line pattern using an exposure system (TME-150RSK; manufactured by Topcon). 2 The colored composition layer was irradiated with an exposure dose of 100 nm (based on 365 nm). The irradiated colored composition layer was immersed in an aqueous developer containing 0.12% nonionic surfactant and 0.04% potassium hydroxide at 24°C for 60 seconds. After rinsing with water, the layer was post-baked in an oven at 230°C for 20 minutes to obtain a colored coating film.

Furthermore, the obtained colored coating film was baked in an oven at 230°C for 60 minutes (additional baking), and the foreign matter between the obtained line patterns was evaluated. The results are shown in Table 8. Smaller numbers in Table 8 indicate fewer foreign matter particles, which contributes to the formation of a good pattern. The evaluation criteria are shown below. 1: No foreign matter was found at all. 2: Approximately 1% to 5% of the area of ​​foreign matter was found between the wires, but no problem was found. 3: Approximately 6% to 15% of the area of ​​foreign matter was found between the wires, but no problem was found. 4: Approximately 16% or more of the area of ​​foreign matter was found between the wires, making the product unusable.
