< method for producing colored curable resin composition >

The colored curable resin composition can be prepared, for example, by mixing the colorant (a), the resin (B), the solvent (E), and the leveling agent (F), and further mixing the mixture with the polymerizable compound (C), the polymerization initiator (D), the polymerization initiation aid (D1), and other components when the pattern is formed by photolithography.

The pigment is preferably mixed with a part or all of the solvent (E) in advance, and dispersed by a bead mill until the average particle diameter of the pigment becomes about 0.2 μm or less. In this case, a part or all of the pigment dispersant and the resin (B) may be blended as necessary. The remaining components are mixed in the thus obtained pigment dispersion liquid so as to have a predetermined concentration, whereby the target colored curable resin composition can be prepared.

The dyes may be dissolved in a part or all of the solvent (E) separately in advance to prepare a solution. The solution is preferably filtered through a filter having a pore size of about 0.01 to 1 μm.

The mixed colored curable resin composition is preferably filtered through a filter having a pore size of about 0.1 to 10 μm.

(3) Color filter

The color filter can be formed from the colored curable resin composition of the present invention. Examples of a method for forming a colored pattern include a photolithography method, an ink jet method, a printing method, and the like. Among them, photolithography is preferable. The photolithography method is a method in which the colored curable composition is applied to a substrate and dried to form a colored curable composition layer, and the colored curable composition layer is exposed to light through a photomask and developed. In the photolithography method, a colored coating film which is a cured product of the colored curable resin composition layer can be formed without using a photomask and/or without performing development at the time of exposure. The colored pattern and the colored coating film formed in this way are the color filter of the present invention.

The film thickness of the color filter to be produced is not particularly limited, and can be suitably adjusted according to the purpose, application, and the like, and is, for example, 0.1 to 30 μm, preferably 0.1 to 20 μm, and more preferably 0.5 to 6 μm.

As the substrate, a glass plate, a resin plate, silicon, a substrate in which a thin film of aluminum, silver/copper/palladium alloy, or the like is formed on the substrate, or the like is used. Other color filter layers, resin layers, transistors, circuits, and the like may be formed on these substrates.

The formation of each color pixel by photolithography can be performed by using a known or conventional apparatus and conditions. For example, the following can be used.

First, a substrate is coated with the colored curable resin composition, and is dried by heating (prebaking) and/or drying under reduced pressure to remove volatile components such as a solvent and dry the composition, thereby obtaining a smooth colored curable resin composition layer.

Examples of the coating method include a spin coating method, a slit coating method, and a slit/spin coating method.

The temperature for heating and drying is preferably 30 to 120 ℃, more preferably 50 to 110 ℃. The heating time is preferably 10 seconds to 60 minutes, and more preferably 30 seconds to 30 minutes.

When the drying is carried out under reduced pressure, the drying is preferably carried out under a pressure of 50 to 150Pa and at a temperature of 20 to 25 ℃.

The film thickness of the colored curable resin composition is not particularly limited, and may be appropriately selected according to the film thickness of the target color filter.

Next, the colored curable resin composition layer is exposed to light through a photomask for forming a target colored pattern. In order to uniformly irradiate parallel light rays to the entire exposure surface and perform precise alignment of the photomask and the substrate on which the colored curable composition layer is formed, an exposure apparatus such as a mask aligner or a stepper is preferably used.

The light source used for exposure is preferably a light source that generates light having a wavelength of 250 to 450 nm. For example, light less than 350nm may be cut off using a filter that cuts off the wavelength region, or light near 436nm, near 408nm, or near 365nm may be selectively extracted using a band-pass filter that extracts these wavelength regions. Specifically, mercury lamps, light emitting diodes, metal halide lamps, halogen lamps, and the like can be given.

The exposed colored curable composition layer is brought into contact with a developer to develop the layer, thereby forming a colored pattern on the substrate. The unexposed portion of the colored curable composition layer is dissolved in a developing solution and removed by development.

As the developer, for example, an aqueous solution of an alkaline compound such as potassium hydroxide, sodium bicarbonate, sodium carbonate, or tetramethylammonium hydroxide is preferable. The concentration of the basic compound in the aqueous solution may be, for example, 0.01 to 10% by mass. Further, the developer may contain a surfactant.

The developing method may be any of a paddle method, a dipping method, a spraying method, and the like. Further, the substrate can be inclined at an arbitrary angle during development.

The developed substrate is preferably washed with water.

Further preferably, the obtained colored pattern is subjected to post-baking.

(4) Display device

The color filter is useful as a color filter used in a display device (for example, a liquid crystal display device, an organic EL device, electronic paper, or the like) and a solid-state imaging element, and particularly as a color filter used in an organic EL device.

Then, 38 parts of acrylic acid and 3, 4-epoxytricyclo [5.2.1.0 ] acrylic acid were added dropwise over 5 hours^2,6]Decan-8-yl ester and acrylic acid 3, 4-epoxytricyclo [5.2.1.0² ^,6]A mixed solution of 289 parts of a mixture of decane-9-yl esters (containing 1:1 ratio in terms of molar ratio) and 125 parts of propylene glycol monomethyl ether acetate. On the other hand, 2-azo was added dropwise over 6 hoursA solution of 33 parts of bis (2, 4-dimethylvaleronitrile) in 235 parts of propylene glycol monomethyl ether acetate. After completion of the dropwise addition, the mixture was held at 80 ℃ for 4 hours and then cooled to room temperature to obtain a copolymer (resin B1) solution containing 35.1% of a solid content and having a viscosity of 125 mPas as measured with a type B viscometer (23 ℃). The weight-average molecular weight Mw of the resulting copolymer was 9.2X 10³The dispersion degree was 2.08, and the acid value in terms of solid content was 77 mg-KOH/g. The resin B1 has the following structural units.

(1) Preparation of coloring composition

The ingredients were mixed in the following proportions and the colorant was dispersed using a bead mill. Thereafter, the beads were removed by filtration to obtain coloring composition 1.

Next, the respective components were mixed at the following ratio to obtain a colored curable resin composition 1.

(2) Production of colored coating film

The colored curable resin composition is applied onto a 5cm square glass substrate (EAGLE XG; manufactured by CORNING) by spin coating so that the post-baking film thickness is 1.7 to 2 μm, and then pre-baked at 100 ℃ for 3 minutes to form a colored curable resin composition layer. After cooling, the colored curable resin composition formed on the substrate was exposed to an exposure apparatus (TME-150 RSK; manufactured by TOPCON Ltd.) in an air atmosphereThe mixture layer has a thickness of 80mJ/cm²The exposure amount (365nm basis) of (A) was irradiated with light. After the light irradiation, the resultant was postbaked at 230 ℃ for 30 minutes in an oven to obtain a colored coating film.

(3) Heat resistance test

The absorbance of the obtained colored coating film was calculated using a color measuring machine (OSP-SP-200; manufactured by OLYMPUS). The colored coating film after the measurement was heated at 230 ℃ for 120 minutes in an oven under an air atmosphere, and then the absorbance was calculated using a color measuring machine. The absorbance retention was determined from the change in absorbance at the maximum absorption wavelength of the colored curable composition film before and after the heat resistance test.
