In recent years, displays have been developed to expand the color reproduction range that can be displayed, and as a part of this, color filters are also required to have darker colors.In order to meet this demand, a coloring composition is required that contains a compound having a maximum absorption wavelength on the longest wavelength side of the absorption spectrum and/or a compound having a shoulder peak wavelength on the longest wavelength side of the absorption spectrum, which is longer than the maximum absorption wavelength on the longest wavelength side of the absorption spectrum of the conventionally known C.I. Pigment Yellow 138.
The wavelength of the shoulder peak on the longest wavelength side of the above absorption spectrum is
The compound is
- When the maximum absorption wavelength on the longest wavelength side of the absorption spectrum is not present on the longest wavelength side of the maximum absorption wavelength on the longest wavelength side of the absorption spectrum of C.I. Pigment Yellow 138,
and,
When the absorption spectrum has two or more inflection points on the longer wavelength side than the maximum absorption wavelength on the longest wavelength side of the absorption spectrum,
It means the average wavelength between the wavelength of the inflection point on the longest wavelength side of the absorption spectrum and the wavelength of the inflection point on the second longest wavelength side of the absorption spectrum.

[Method of producing colored composition]
The colored composition of the present invention can be prepared, for example, by mixing the compound (I), the solvent (E), and, if necessary, the resin (B), the polymerizable compound (C), the polymerization initiator (D), the polymerization initiator aid (D1), the colorant (A1), the leveling agent (F), the antioxidant (G) and/or other components. The mixing can be carried out using known or conventional equipment and conditions.
It is preferable to use the compound (I) in the form of a compound (I)-containing liquid obtained by mixing the compound (I) in advance with a part or all of the solvent (E) and dispersing the compound (I) until the average particle size of the compound (I) becomes about 0.2 μm or less using a bead mill or the like. In this case, the dispersant and the resin (B) may be mixed in part or all as necessary.
It is preferable to use the colorant (A1) in the form of a liquid containing the colorant (A1) that is previously mixed with a part or all of the solvent (E) and dispersed using a bead mill or the like until the average particle size of the colorant (A1) becomes about 0.2 μm or less. In this case, the dispersant and a part or all of the resin (B) may be blended as necessary.
It is preferable to use the compound (I) in the form of a solution in which the compound (I) is dissolved in a part or all of the solvent (E) in advance (the solution is included in the compound (I)-containing liquid). Furthermore, it is preferable to filter the compound (I)-containing liquid through a filter having a pore size of about 0.01 μm or more and 1 μm or less.
It is preferable to use the colorant (A1) in the form of a solution in which it is dissolved in advance in a part or all of the solvent (E) (the solution is included in a colorant (A1)-containing liquid). Furthermore, it is preferable to filter the colorant (A1)-containing liquid through a filter having a pore size of about 0.01 μm or more and 1 μm or less.
The mixed coloring composition is preferably filtered through a filter having a pore size of about 0.01 μm or more and 10 μm or less.

[Color filter]
A color filter can be formed from the colored composition of the present invention.
A colored coating film can be formed by applying the colored composition to a substrate, removing volatile components such as a solvent, and drying the substrate. The colored coating film thus formed is included in the color filter of the present invention.
Examples of methods for forming a colored pattern include photolithography, inkjet, and printing. Among them, photolithography is preferred. The photolithography is a method in which the colored composition is applied to a substrate, dried to form a colored composition layer, and the colored composition layer is exposed through a photomask and developed. In the photolithography, 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 colored pattern or colored coating film thus formed is the color filter of the present invention.
The thickness of the color filter to be produced is not particularly limited and can be appropriately adjusted depending on the purpose and application, and is, for example, 0.1 to 30 μm, preferably 0.1 to 20 μm, and more preferably 0.5 to 6 μm.

The substrate may be a glass plate such as quartz glass, borosilicate glass, alumina silicate glass, or soda lime glass with a silica-coated surface; a resin plate such as polycarbonate, polymethylmethacrylate, or polyethylene terephthalate; silicon; or a substrate having a thin film of aluminum, silver, or a silver/copper/palladium alloy formed thereon. On these substrates, other color filter layers, resin layers, transistors, circuits, etc. may be formed.

The formation of each color pixel by photolithography can be carried out using known or conventional devices and conditions. For example, the pixel can be produced as follows.
First, the colored composition is applied onto a substrate, and then dried by heating (pre-baking) and/or drying under reduced pressure to remove volatile components such as a solvent, thereby obtaining a smooth colored composition layer.
Examples of the coating method include a spin coating method, a slit coating method, and a slit and spin coating method.
The temperature in the case of heat drying 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. In the case of reduced pressure drying, it is preferably performed under a pressure of 50 to 150 Pa at a temperature range of 20 to 25° C. The film thickness of the coloring composition layer is not particularly limited and may be appropriately selected depending on the film thickness of the intended color filter.

The colored composition layer is then exposed through a photomask to form a desired colored pattern.
The pattern on the photomask is not particularly limited, and a pattern according to the intended use is used. As the light source used for exposure, a light source that generates light with a wavelength of 250 to 450 nm is preferable. For example, light of less than 350 nm may be cut using a filter that cuts this wavelength range, or light of around 436 nm, around 408 nm, and around 365 nm may be selectively extracted using a bandpass filter that extracts these wavelength ranges. Specific examples of the light source include a mercury lamp, a light-emitting diode, a metal halide lamp, and a halogen lamp.
It is preferable to use an exposure device such as a mask aligner or a stepper, since it is possible to uniformly irradiate the entire exposure surface with parallel light rays and to accurately align the photomask with the substrate on which the colored composition layer is formed.

The colored composition layer after exposure is brought into contact with a developer and developed to form a colored pattern on the substrate. By development, the unexposed areas of the colored composition layer are dissolved in the developer and removed.
The developer is preferably an aqueous solution of an alkaline compound such as potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, or tetramethylammonium hydroxide.
The concentration of the alkaline compound is preferably from 0.01 to 10% by mass, and more preferably from 0.02 to 5% by mass. The developer may contain a surfactant.
The developing method may be any of a puddle method, a dipping method, a spray method, etc. Furthermore, the substrate may be inclined at an arbitrary angle during the developing.
After development, the substrate is preferably washed with water.
Furthermore, it is preferable to subject the obtained colored pattern to post-baking.
The post-baking temperature is preferably 150 to 250° C., more preferably 160 to 235° C. The post-baking time is preferably 1 to 120 minutes, more preferably 10 to 60 minutes. The color filter, which is the colored pattern or colored coating film thus obtained, may be further subjected to a surface coating treatment in order to impart various properties.

The color filter is useful as a color filter for use in display devices (e.g., liquid crystal display devices, organic EL devices, electronic paper, etc.) and solid-state imaging devices, in particular as a color filter for use in liquid crystal display devices.
