Note that this content does not include the content of the pigment dispersant. When the content of the leveling agent (F) is within the above range, the flatness of the color filter can be improved.

[0206] <Other ingredients> The colored curable resin composition may contain additives known in the technical field, such as fillers, other polymer compounds, adhesion promoters, quenchers, antioxidants, light stabilizers, and chain transfer agents, as necessary.

[0207] <Method for producing colored curable resin composition> The colored curable resin composition can be prepared by mixing the colorant (A), alkali-soluble resin (B), polymerizable compound (C), polymerization initiator (D), and optionally the polymerization initiator aid (D1), solvent (E), thiol compound (T), leveling agent (F), and other components. Mixing can be carried out using known or conventional equipment and conditions. The colorant (A) may be mixed with part or all of the solvent (E) in advance and dispersed using a bead mill or the like until the average particle size is about 0.2 μm or less, and used as a colorant-containing liquid. In this case, it is preferable to use it as a colorant-containing liquid. In this case, the dispersant and part or all of the alkali-soluble resin (B) may be blended as needed. The remaining components are mixed with the colorant-containing liquid obtained in this manner to achieve the desired concentration, thereby preparing the desired colored curable resin composition. When a dye is contained as the colorant (A), the dye may be dissolved in advance in part or all of the solvent (E) to prepare a solution, which is then preferably filtered through a filter having a pore size of about 0.01 to 1 μm.

[0208] <Color filter manufacturing method> A color filter can be formed from the colored curable resin composition of the present invention. Methods for producing a colored pattern include photolithography, inkjet printing, and printing. Among these, photolithography is preferred. The photolithography method involves applying the colored curable resin composition to a substrate, drying the composition to form a colored composition layer, and then exposing and developing the colored composition layer through a photomask. In the photolithography method, a colored coating film, which is a cured product of the colored composition layer, can be formed by not using a photomask during exposure and / or not developing the layer. The colored pattern or colored coating film thus formed is the color filter of the present invention.

[0209] The film thickness of the color filter to be produced is not particularly limited and can be adjusted appropriately depending on the purpose, application, etc., and is, for example, 30 μm or less, preferably 20 μm or less, more preferably 6 μm or less, even more preferably 4.5 μm or less, and preferably 0.1 μm or more, more preferably 0.2 μm or more, even more preferably 0.3 μm or more.

[0210] 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 (hexamethyldisilazane) may be used.

[0211] The 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 curable resin composition is applied to a substrate, and then heated and dried (prebaked) and / or dried under reduced pressure to remove volatile components such as solvents and dry the composition, thereby obtaining a smooth colored composition layer. Examples of application methods include spin coating, slit coating, and slit and spin coating. The temperature for heat drying is preferably 30°C to 120°C, more preferably 50°C 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, the drying is preferably performed under a pressure of 50 Pa to 150 Pa and at a temperature of 20°C to 25°C. The thickness of the colored composition layer is not particularly limited and may be appropriately selected depending on the desired thickness of the color filter.

[0212] Next, the colored composition layer is exposed through a photomask to form a desired colored pattern. The pattern on the photomask is not particularly limited, and a pattern appropriate for the intended use is used. In addition, it is preferable to use an exposure device such as a mask aligner or a stepper, since this allows uniform irradiation of parallel light rays over the entire exposure surface and allows accurate alignment between the photomask and the substrate on which the colored composition layer is formed. When a colored coating film is formed, exposure can be performed without using a photomask.

[0213] The light source used for exposure is preferably a light source that emits light with a wavelength of 250 nm or more and 450 nm or less. 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.

[0214] A colored pattern is formed on the substrate by contacting the exposed colored composition layer with a developer and developing it. The unexposed portions of the colored composition layer are dissolved and removed by the 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% by mass or more and 10% by mass or less, more preferably 0.03% by mass or more and 5% by mass or less. 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, the substrate is preferably washed with water.

[0215] Furthermore, the obtained colored pattern or colored coating film is preferably post-baked. The post-baking temperature is preferably from 80° C. to 250° C., more preferably from 100° C. to 245° C. The post-baking time is preferably from 1 minute to 120 minutes, more preferably from 2 minutes to 30 minutes.

[0216] The colored pattern and colored coating film thus obtained are useful as a color filter.

[0217] Use of the colored curable resin composition of the present invention can improve the adhesion of the formed color filter. Furthermore, use of the colored curable resin composition of the present invention can preferably reduce the generation of residues during development in the production of color filters. Note that adhesion refers to the strength of adhesion between the color filter and a substrate, etc., when the color filter is formed. Poor adhesion increases the likelihood of peeling or chipping of the color filter. In the present invention, the adhesion of the color filter was evaluated by observing the resulting colored pattern (having a dot pattern) under a microscope and counting the number of dots remaining without peeling. Furthermore, residue refers to foreign matter that does not form a pattern and remains in the unexposed areas when the colored pattern after development is observed using an electron microscope (for example, at a magnification of 25,000 times).

[0218] <Display devices, solid-state image sensors> The color filter is useful as a color filter for use in display devices (for example, liquid crystal display devices, organic EL devices, electronic paper, etc.), solid-state imaging devices, etc. [Example]

A solution containing 16.5 parts of 3-phenoxybenzyl acrylate, 83.5 parts of glycidyl methacrylate, 5.0 parts of azobis(isobutyronitrile), and 52.5 parts of propylene glycol monomethyl ether acetate was continuously added dropwise to the flask using the dropping funnel over 3 hours while maintaining the temperature inside the flask at 90±1°C. After completion of the dropping, the temperature inside the flask was returned to 90±1°C and an aging reaction was carried out for 6 hours. After the reaction, the reaction mixture was cooled to below 40°C, and 0.15 parts of polymerization inhibitor, 42.3 parts of acrylic acid, 2.0 parts of triphenylphosphine, and 68.3 parts of propylene glycol monomethyl ether acetate were added. The temperature in the flask was raised to 110°C, and an addition reaction was carried out at a temperature of 110±1°C to obtain a resin solution. To the resulting resin solution, 20.0 parts of succinic anhydride and 30.0 parts of propylene glycol monomethyl ether acetate were added and the addition reaction was carried out at 110°C. A copolymer (Resin B6) solution with a viscosity of 94 mPa·s measured with a Brookfield viscometer (25°C) and a solids content of 39.9% was obtained. The weight-average molecular weight (Mw) of the resulting copolymer was 9650.

[0248] (Production of colored patterns) HMDS (Tokyo Chemical Industry Co., Ltd.; hexamethyldisilazane) was vapor-deposited on the surface of a 4-inch silicon substrate. A colored curable resin composition was applied by spin coating to the HMDS-deposited side of the silicon substrate, and then pre-baked at 80°C for 2 minutes to obtain a colored composition layer. After cooling, the substrate on which the colored composition layer was formed was exposed to 50 mJ / cm2 using an exposure machine (NSR-2205i11D; Nikon Corporation). 2The film was irradiated with light at an exposure dose of 0.8 μm, 1.0 μm, and / or 2.0 μm square using a photomask (pitches of 1.6 μm, 2.0 μm, and 4.0 μm, respectively). The colored composition layer after light irradiation was immersed and developed in an aqueous developer containing 0.1% tetramethylammonium hydroxide at 23° C. for 30 seconds, washed with water, and then post-baked on a hot plate at 230° C. for 10 minutes to obtain a colored pattern after post-baking.
