< other ingredients >
The colored curable resin composition of the present invention may contain additives known in the art, such as a filler, another polymer compound, an adhesion promoter, a light stabilizer, and a chain transfer agent, as required.
< method for producing colored curable resin composition >

< color Filter >
A colored pattern 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 resin composition is applied to a substrate and dried to form a colored composition layer, and the colored composition layer is exposed to light through a photomask and developed. In the photolithography method, a colored coating film as a cured product of the colored composition layer can be formed without using a photomask and/or without developing at the time of exposure. The colored pattern and the colored coating film thus formed 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 such as quartz glass, borosilicate glass, alumina silicate glass, soda lime glass having a silica-coated surface, a resin plate such as polycarbonate, polymethyl methacrylate, or polyethylene terephthalate, a substrate of silicon, a substrate having a thin film of aluminum, silver/copper/palladium alloy, or the like formed on the substrate, or the like can be 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 under known or conventional apparatus and conditions. For example, it can be produced as follows.
First, a colored curable resin composition is applied onto a substrate, 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 composition layer.
Examples of the coating method include spin coating, slit and spin coating.
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 composition layer is not particularly limited, and may be appropriately selected according to the film thickness of the target color filter.
Next, the colored composition layer is exposed through a photomask for forming a target colored pattern. The pattern on the photomask is not particularly limited, and a pattern corresponding to the intended use may be 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 of less than 350nm may be cut off by a filter that cuts off the wavelength region, or light of around 436nm, 408nm, or 365nm may be selectively extracted by 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.
In order to uniformly irradiate the entire exposure surface with parallel light beams or to precisely align the photomask with the substrate on which the colored composition layer is formed, it is preferable to use an exposure device such as a mask aligner or a stepper.
The exposed colored composition layer is brought into contact with a developer to develop the colored composition layer, thereby forming a colored pattern on the substrate. The unexposed portion of the colored composition layer is dissolved in a developer 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 these basic compounds in the aqueous solution is preferably 0.01 to 10% by mass, more preferably 0.03 to 5% by mass. Further, the developer may contain a surfactant.
The developing method may be any of a paddle (paddle) method, a dipping method, a spraying method, and the like. The substrate may be further inclined at an arbitrary angle during development.
The developed substrate is preferably washed with water.
The obtained colored pattern is preferably subjected to post-baking. The post-baking temperature is preferably 150-250 ℃, and more preferably 160-235 ℃. The post-baking time is preferably 1 to 120 minutes, and more preferably 10 to 60 minutes.
According to the coloring composition of the invention, a color filter with particularly excellent light resistance can be manufactured. 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 is particularly useful as a color filter used in a liquid crystal display device.
