Description

[Technical field]

[0001] The present invention relates to a coloring composition used for forming a color filter used in a solid-state imaging device, an image display device, or the like. [Background technology]

[0002] In recent years, the demand for color filters used in liquid crystal displays, organic electroluminescence displays, digital cameras, smartphones, infrared sensors, etc. has been growing due to their widespread use. Color filters separate the light that passes through them, and these colors are then synthesized to form an image. For this reason, color filters are required to have high brightness, high contrast, and color reproducibility.

[0003] As colorants excellent in luminance, contrast and color reproducibility, the use of phthalocyanine compounds described in Patent Documents 1 to 4 has been investigated. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2019-113732 A [Patent Document 2] Patent Publication No. 2021-056382 [Patent Document 3] International Publication No. 2023 / 002875 [Patent Document 4] International Publication No. 2023 / 120268 Summary of the Invention [Problem to be solved by the invention]

[0005] As a result of extensive investigations into the phthalocyanine compounds described in Patent Documents 1 to 4, it was found that coloring compositions using these phthalocyanine compounds generate foreign matter during storage. It was also found that there are problems with development residues and foreign matter generation in films under high temperature and high humidity conditions.

[0006] An object of the present invention is to provide a coloring composition which is excellent in storage stability and developability and is capable of forming a film which is less likely to generate foreign matter in a high-temperature and high-humidity environment. [Means for solving the problem]

[0007] The present invention relates to a coloring composition comprising a colorant (A), a resin (B), and an organic solvent (C), the color material (A) includes a green color material (A1) and a blue color material (A2); The present invention relates to a coloring composition, wherein the green colorant (A1) contains a green colorant (a1) represented by the following general formula (1):

[0008] General formula (1) [ka] (In general formula (1), X1~X 16 each independently represents a hydrogen atom, a halogen atom, or -Y1-R1, where Y1 represents a divalent linking group and R1 represents a monovalent organic group. 16 At least one of them represents a halogen atom, and at least one of them represents -Y1-R1. M represents a metal atom, a metal oxide, or a metal halide. Effect of the Invention

[0009] According to the present invention, it is possible to provide a coloring composition capable of forming a film having excellent storage stability and developability and less generation of foreign matter under high temperature and high humidity conditions. The present invention also provides a film, a color filter, a solid-state imaging device, and an image display device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiment for carrying out the colored composition of the present invention will be described in detail. Note that the present invention is not limited to the following embodiment, and can be modified within the scope of the problem that can be solved.

[0011] In this specification, unless otherwise specified, "(meth)acryloyl", "(meth)acrylic", "(meth)acrylic acid", "(meth)acrylate", or "(meth)acrylamide" respectively mean "acryloyl and / or methacryloyl", "acrylic and / or methacrylic", "acrylic acid and / or methacrylic acid", "acrylate and / or methacrylate", or "acrylamide and / or methacrylamide". In addition, "CI" means Color Index (CI; published by The Society of Dyers and Colourists). In this specification, a polymerizable unsaturated group is an ethylenically unsaturated double bond. As used herein, a monomer is a compound that will polymerize to form a resin. A monomer is in an unreacted state, and a monomer unit is a monomer that has been polymerized to form a polymer. In this specification, for low molecular weight compounds whose molecular weight can be specified, the molecular weight is a calculated value or measured by ESI-MS (electrospray ionization mass spectrometry), and for compounds having a molecular weight distribution, the molecular weight is a polystyrene-equivalent weight average molecular weight measured by gel permeation chromatography using tetrahydrofuran as a solvent. In this specification, a numerical range expressed using "to" means a range that includes the numerical values ​​before and after "to" as the lower limit and upper limit.

[0012] <Coloring composition> A coloring composition according to one embodiment of the present invention is a coloring composition comprising a colorant (A), a resin (B), and an organic solvent (C), the color material (A) includes a green color material (A1) and a blue color material (A2); The green color material (A1) is characterized in that it contains a green color material (a1) represented by the following general formula (1).

[0013] General formula (1) [ka] (In general formula (1), X1~X 16 each independently represents a hydrogen atom, a halogen atom, or -Y1-R1, where Y1 represents a divalent linking group and R1 represents a monovalent organic group. 16 At least one of them represents a halogen atom, and at least one of them represents -Y1-R1. M represents a metal atom, a metal oxide, or a metal halide.

[0014] The mechanism by which the colored composition having the above-mentioned configuration can solve the problems of the present invention is not clear, but is speculated as follows.

[0015] The green colorant (a1) represented by the general formula (1) (hereinafter, simply referred to as the green colorant (a1)) is not sufficiently dissolved in an organic solvent, and is prone to association and aggregation over time when the concentration is high or when stored at low temperature. However, when the blue colorant (A2) having a different structure from the green colorant (a1) is used in combination, the blue colorant (A2) acts on the green colorant (a1) and prevents the green colorant (a1) from associating and aggregating with itself, suppressing the generation of foreign matter during storage. It is presumed that the generation of residue due to aggregation during development and the generation of foreign matter in high temperature and high humidity environments can be suppressed by making the green colorant (a1) less likely to associate and aggregate. In addition, the blue colorant (A2) can reduce the impact on brightness and contrast.

[0080] [Resin (B)] The coloring composition of the present invention contains a resin (B).

[0081] Resin (B) used mainly to disperse color material (A) is called dispersion resin, and resin (B) used mainly to impart film resistance is called binder resin. One type of resin (B) may have both the functions of dispersion resin and binder resin. Such uses of resin (B) are just examples, and resin (B) can also be used for other purposes.

[0082] The resin (B) is not particularly limited, and known compounds can be used, such as (meth)acrylic resin, styrene resin, styrene / (meth)acrylic resin, epoxy resin, urethane resin, urethane acrylic resin, polycarbonate resin, polyester resin, polyether resin, polyimide resin, polyamideimide resin, polysiloxane resin, and cyclic olefin resin.

[0083] The weight average molecular weight of the resin (B) is preferably from 3,000 to 200,000, and more preferably from 4,000 to 150,000.

[0084] The resin (B) can be used alone or in combination of two or more kinds.

[0085] The content of the resin (B) is preferably from 1 to 70 mass %, and more preferably from 5 to 60 mass %, in 100 mass % of the nonvolatile content of the colored composition.

[0086] (Resin having an aromatic carboxyl group (B1)) From the viewpoint of storage stability and suppression of foreign matter under high temperature and high humidity environments, it is preferable that the resin (B1) contains a resin (B1) having an aromatic carboxyl group as a dispersing resin. It is presumed that the strong interaction between the aromatic ring in the green color material (a1) and the aromatic carboxyl group suppresses association and aggregation of the green color material (a1) itself. In this specification, the aromatic carboxyl group refers to a group having a structure in which one or more carboxyl groups are bonded to an aromatic ring.

[0087] The aromatic carboxyl group may be contained in either the main chain or the side chain of the resin, but is preferably contained in the main chain.

[0088] The aromatic carboxyl group preferably has 1 to 4 carboxyl groups bonded to the aromatic ring.

[0089] The resin (B1) having an aromatic carboxyl group preferably contains a resin having a main chain based on an aromatic carboxylic acid ester moiety having an ester bond, which is a reaction product site between an aromatic compound having two or more acid anhydride groups and a compound having two or more hydroxyl groups, and a side chain based on a vinyl polymer moiety.

[0090] The aromatic carboxylate moiety in the main chain is obtained by a ring-opening reaction between an aromatic compound having two or more acid anhydride groups and a compound having two or more hydroxyl groups, and an aromatic carboxyl group is generated simultaneously with the formation of an ester bond.

[0091] The vinyl polymer moiety in the side chain acts as a steric repulsion moiety and suppresses the association and aggregation of the green color material (a1). The vinyl polymer moiety in the side chain can be obtained, for example, by the following two methods. The first method is a method of copolymerizing a monomer in the presence of a compound having two or more hydroxyl groups. The compound having two or more hydroxyl groups is preferably a compound having two hydroxyl groups and one thiol group in the molecule. The second method is a method in which a monomer is copolymerized in the presence of a reaction product between an aromatic compound having two or more acid anhydride groups and a hydroxyl group of a compound having two or more hydroxyl groups. The difference between the above two methods is whether the vinyl polymer moiety is introduced first or later by copolymerizing the monomer. Although the molecular weight may differ slightly depending on various conditions, the same compound can theoretically be synthesized if the raw materials and reaction conditions are the same.

[0092] The main chain and the side chain will be described in detail below.

[0093] [Main Chain] The aromatic carboxylate moiety can be obtained by a ring-opening reaction between an anhydride group of an aromatic compound having two or more acid anhydride groups and a compound having two or more hydroxyl groups.

Also, an imaging element such as a CCD or a CMOS may be formed on the substrate. Also, an undercoat layer may be provided on the substrate as necessary to improve adhesion with the upper layer, prevent diffusion of substances, and flatten the surface.

[0315] The coating method is not particularly limited, and any known method can be used, such as a dropping method, a slit coating method, a spray method, a roll coating method, a spin coating method, a casting coating method, an inkjet method, flexographic printing, screen printing, gravure printing, and offset printing.

[0316] The thickness of the membrane can be appropriately adjusted depending on the purpose, and is preferably 0.05 to 20.0 μm, more preferably 0.3 to 10.0 μm.

[0317] [Drying process] The method for drying the film applied to the substrate is not particularly limited, and any known method can be used, such as reduced pressure drying using a vacuum drying device, heat drying using a hot plate, an IR oven, a convection oven, or a combination of these methods.

[0318] The drying temperature and time can be appropriately adjusted. The drying temperature is preferably about 50 to 130° C., and the drying time is preferably about 5 seconds to 5 minutes.

[0319] Next, a pattern is formed. Examples of a method for forming a pattern include a photolithography method and a dry etching method. Among these, a photolithography method is preferable. Note that, when the film is used as a flat film, the step of forming a pattern is not necessary.

[0320] The method for forming the pattern will now be described in detail.

[0321] When a pattern is formed by a photolithography method, for example, the coloring composition of the present invention is applied onto a substrate, and a layer formed by drying is exposed to light in a pattern through a mask (exposure process), and the unexposed parts are removed with an alkaline developer (development process), and then the pattern is heat-treated (post-bake process).

[0322] [Exposure process] In the exposure process, the layer formed by coating and drying is exposed to a specific pattern through a mask using an exposure device such as a stepper. This allows the exposed portion to be cured. Examples of active energy rays used for exposure include ultraviolet rays such as g-rays (wavelength 436 nm), h-rays (wavelength 405 nm), and i-rays (wavelength 365 nm). Light with a wavelength of 300 nm or less can also be used. Examples of light with a wavelength of 300 nm or less include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm). When using light with a specific wavelength, an optical filter can also be used. In addition, the exposure may be performed by continuous irradiation with light, or by repeating irradiation and pause of light in a short cycle (for example, on the order of milliseconds or less) (pulse exposure). In addition, a plurality of active energy rays may be used in combination, or exposure may be performed in a plurality of steps.

[0323] [Development process] Next, an alkaline development process is carried out, whereby the unexposed portions of the layer are dissolved in an alkaline developer, and only the hardened portions remain, yielding a patterned film. Examples of the alkaline developer include aqueous solutions containing alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium metasilicate, aqueous ammonia, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, choline, pyrrole, piperidine, 1,8-diazabicyclo-[5.4.0]-7-undecene, etc. Two or more of these alkaline compounds can be used in combination. The alkaline developer may contain a surfactant and an organic solvent in addition to the alkaline compound and water. The concentration of the alkaline developer is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. The pH of the alkaline developer is preferably 11 to 13, more preferably 11.5 to 12.5. When used at an appropriate pH, it suppresses roughening and peeling of the pattern and improves the remaining film rate after development. Examples of the developing method include a dipping method, a spraying method, a puddle method, etc. The developing temperature is preferably 15 to 40° C. After the alkaline development, it is preferable to wash with pure water.

[0324] [Post-bake process] After development, a heat treatment (post-baking) is performed, which improves the resistance of the film. The temperature is preferably 100 to 300° C., more preferably 180 to 260° C. The time is preferably about 2 minutes to 2 hours. When a material with low heat resistance is used for the substrate, when a substrate having an organic electroluminescence element as the light-emitting layer is used, or from the viewpoint of the environment, the temperature is preferably 180° C. or less.
