Description

[Technical Field]

[0001] The present invention relates to a composition, a cured product thereof, and a method for producing the cured product. [Background technology]

[0002] A method of adjusting the amount of light using a light-shielding filter is known. Patent Document 1 describes the use of a light-shielding filter for adjusting illuminance in a lithography exposure apparatus for semiconductor integrated circuits and the like.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-266098 [Patent Document 2] Japanese Patent Application Publication No. 01-198701 Summary of the Invention

[0004] The light-shielding filters used in Patent Documents 1 and 2 are made of thin metal films or metal meshes, which are difficult to form on uneven surfaces or on large-area light-shielding targets, and there are cases where the locations where they can be formed are limited. The present inventors have investigated the formation of a light-shielding filter using a curable composition containing a black pigment such as carbon and a curable resin. However, the above-mentioned curable composition has a problem in that it is difficult to continuously discharge from a discharge device such as a die or a nozzle, and the discharge port becomes clogged in a short time. Therefore, the present inventors have investigated the formation of a light-shielding filter using a curable composition containing a black dye and a curable resin. However, depending on the combination of black dye and curable resin, there are problems such as a high total light transmittance that makes it impossible to obtain a sufficient light-shielding effect, or a high haze that makes it impossible to obtain a sufficient light-shielding effect.

[0005] The present invention has been made in view of the above problems, and has as its main object to provide a composition that has an excellent balance between continuous dischargeability and light-shielding properties.

[0006] As a result of extensive research, the present inventors have found that a composition having an excellent balance between continuous dischargeability and light-blocking properties can be obtained by combining a specific black dye with a specific type of cationically polymerizable component.

[0007] That is, the present disclosure provides a composition comprising a cationically polymerizable component, a black dye, and a photoacid generator, wherein the cationically polymerizable component comprises an alicyclic epoxy compound and at least one selected from a polyfunctional aliphatic epoxy compound, a hydroxyl group-containing oxetane compound, and a vinyl ether compound, and the black dye is at least one selected from an azo-based black dye and a nigrosine-based black dye.

[0021] According to the present disclosure, since the above-described composition is used, a cured product having excellent shape stability and light-blocking properties can be produced with good productivity. DETAILED DESCRIPTION OF THE INVENTION

[0022] The present disclosure relates to a composition, a cured product using the same, and a method for producing the cured product. The composition, cured product, and method for producing the cured product of the present disclosure will be described in detail below.

[0023] A. Composition The composition of the present disclosure is a composition comprising a cationically polymerizable component, a black dye, and a photoacid generator, wherein the cationically polymerizable component comprises an alicyclic epoxy compound and at least one selected from a polyfunctional aliphatic epoxy compound, a hydroxyl group-containing oxetane compound, and a vinyl ether compound, and the black dye is at least one selected from an azo-based black dye and a nigrosine-based black dye.

[0024] The composition of the present disclosure has an excellent balance between continuous dischargeability and light-blocking properties. The light-blocking property means that a cured film having excellent light-blocking properties can be formed, specifically, that a cured film having a low total light transmittance and a low haze value can be formed.

[0025] The reason why the composition has an excellent balance between continuous dischargeability and light-shielding property is not clear, but is presumed to be as follows.

[0026] That is, by combining the specific cationically polymerizable component and the specific black dye, the two can exhibit excellent compatibility, which results in the composition having excellent continuous discharge properties. Furthermore, due to the excellent compatibility, the black dye is uniformly dispersed in the coating film of the composition, and precipitation of the black dye from the cured product is reduced, resulting in the composition being able to form a cured product with low total light transmittance and low haze. Furthermore, since the composition is a combination of the specific cationically polymerizable component and the specific black dye, the black dye is less likely to deteriorate during curing, which also makes it possible to easily form a cured product with low total light transmittance and low haze. For these reasons, the composition has excellent continuous discharge properties and light-shielding properties. Furthermore, since the black dye is less likely to precipitate from the cured product as described above, the black dye is less likely to precipitate even under high temperature and high humidity conditions, and the composition has excellent resistance to moist heat. Furthermore, the excellent continuous dischargeability and light-shielding properties make it easy to adjust the light-shielding degree of the light-shielding film and also to make it easy to make the film thinner.

[0027] Each component constituting the composition of the present disclosure will be described in detail below.

[0028] 1. Cationic polymerizable component The cationically polymerizable component is a compound that undergoes a polymerization or crosslinking reaction in the presence of an acid. The cationically polymerizable component comprises one or more cationically polymerizable compounds having a cationically polymerizable group.

[0029] Examples of the cationically polymerizable group include cyclic ether groups such as an epoxy group, an oxetanyl group, a cyclic lactone group, a cyclic acetal group, a cyclic thioether group, and a spiroorthoester group, and a vinyl ether group. That is, examples of the cationically polymerizable compound include cyclic ether compounds such as epoxy compounds, oxetane compounds, cyclic lactone compounds, cyclic acetal compounds, cyclic thioether compounds, and spiroorthoester compounds, and vinyl ether compounds. Here, the epoxy compound is a compound having an epoxy group as a cationically polymerizable group. Therefore, a compound having both an epoxy group and an oxetanyl group, and a compound having both an epoxy group and a vinyl ether group are included in the epoxy compound. The oxetane compound is a compound that has an oxetanyl group as a cationically polymerizable group but does not have an epoxy group. Therefore, a compound that has both an oxetanyl group and a vinyl ether group falls under the category of oxetane compound. The vinyl ether compound is a compound having a vinyl ether group as a cationically polymerizable group, but not having an epoxy group or an oxetane group. The cationically polymerizable compound other than the epoxy compound, the oxetane compound, and the vinyl ether compound is a compound having no epoxy group, no oxetanyl group, and no vinyl ether group.

[0030] In the present disclosure, the cationically polymerizable component includes an alicyclic epoxy compound and at least one compound selected from a polyfunctional aliphatic epoxy compound, a hydroxyl group-containing oxetane compound, and a vinyl ether compound. That is, the cationically polymerizable component contains an alicyclic epoxy compound as an essential component, and further contains at least one essential component selected from a polyfunctional aliphatic epoxy compound, a hydroxyl group-containing oxetane compound, and a vinyl ether compound. Therefore, the cationically polymerizable component may contain only an alicyclic epoxy compound and a polyfunctional aliphatic epoxy compound among the alicyclic epoxy compound, the polyfunctional aliphatic epoxy compound, the hydroxyl group-containing oxetane compound, and the vinyl ether compound, or may contain only an alicyclic epoxy compound, a polyfunctional aliphatic epoxy compound, and a hydroxyl group-containing oxetane compound, or may contain all of an alicyclic epoxy compound, a polyfunctional aliphatic epoxy compound, a hydroxyl group-containing oxetane compound, and a vinyl ether compound. In the present disclosure, the cationically polymerizable component preferably contains, together with an alicyclic epoxy compound, at least one selected from a polyfunctional aliphatic epoxy compound and a hydroxyl group-containing oxetane compound, and particularly preferably contains at least a polyfunctional aliphatic epoxy compound. This is because the composition has a better balance of continuous dischargeability and light-blocking properties. In addition, the composition has excellent moist heat resistance.

[0031] The total content of the alicyclic epoxy compound, polyfunctional aliphatic epoxy compound, hydroxyl group-containing oxetane compound, and vinyl ether compound is preferably 10 to 90 parts by mass, more preferably 20 to 80 parts by mass, particularly preferably 30 to 70 parts by mass, and most preferably 40 to 60 parts by mass, per 100 parts by mass of the cationically polymerizable component. This is because the composition has an excellent balance between continuous dischargeability and light-blocking properties. Furthermore, the composition has excellent moist heat resistance. Hereinafter, in this specification, the term "total of alicyclic epoxy compounds, polyfunctional aliphatic epoxy compounds, hydroxyl group-containing oxetane compounds, and vinyl ether compounds" refers to the total of alicyclic epoxy compounds, polyfunctional aliphatic epoxy compounds, hydroxyl group-containing oxetane compounds, and vinyl ether compounds contained in the cationically polymerizable component. For example, in the case where the cationically polymerizable component contains only alicyclic epoxy compounds and polyfunctional aliphatic epoxy compounds among alicyclic epoxy compounds, polyfunctional aliphatic epoxy compounds, hydroxyl group-containing oxetane compounds, and vinyl ether compounds, and does not contain hydroxyl group-containing oxetane compounds or vinyl ether compounds, the term "total of alicyclic epoxy compounds and polyfunctional aliphatic epoxy compounds" refers to the total of alicyclic epoxy compounds and polyfunctional aliphatic epoxy compounds.

[0032] (1) Alicyclic epoxy compounds The alicyclic epoxy compound is a compound having at least one alicyclic epoxy group, i.e., a cycloalkene oxide structure, in the molecule, and may have multiple alicyclic epoxy groups in one molecule, or may have an epoxy group other than the alicyclic epoxy group. Furthermore, two or more of the alicyclic epoxy compounds may be used in combination. A compound having an aromatic ring also falls under the category of an alicyclic epoxy compound if it has an alicyclic epoxy group. The cycloalkene oxide structure is a structure in which an aliphatic ring and an epoxy ring share a part of the ring structure, such as a cyclohexene oxide structure or a cyclopentene oxide structure, which is obtained by epoxidizing a cyclohexene ring-containing compound or a cyclopentene ring-containing compound with an oxidizing agent.

[0033] Among the above-mentioned alicyclic epoxy compounds, examples of compounds having one cycloalkene oxide structure include 3,4-epoxycyclohexylmethyl acrylate, 3,4-epoxycyclohexylmethyl methacrylate, dicyclopentadiene diepoxide, dioctyl epoxyhexahydrophthalate, di-2-ethylhexyl epoxyhexahydrophthalate, 1-epoxyethyl-3,4-epoxycyclohexane, and 1,2-epoxy-2-epoxyethylcyclohexane.

[0034] Further, examples of the compound having two cycloalkene oxide structures include a compound having a structure in which two cycloalkene oxide structures are condensed directly or via a cycloalkane structure, and a compound having a structure in which two cycloalkene oxide structures are linked by a linking group. Specific examples of compounds having a structure in which two cycloalkene oxide structures are condensed directly or via a cycloalkane structure include compounds represented by the following formulas (1-1) to (1-4), and specific examples of compounds having a structure in which two cycloalkene oxide structures are linked by a linking group include a compound represented by the following formula (1-5).

[0198] In the present disclosure, it is preferable to contain a compound represented by the above formula (5-1) or a compound represented by the above formula (5-2), and it is particularly preferable to contain a compound represented by the above formula (5-2). This is because the composition has an excellent balance between continuous dischargeability and light-blocking properties. In addition, the composition has excellent moist heat resistance.

[0199] The content of the sensitizer is preferably from 0.1 to 5 parts by mass, more preferably from 0.2 to 3 parts by mass, and particularly preferably from 0.5 to 2 parts by mass, per 100 parts by mass of the solid content of the composition, because this provides the composition with an excellent balance between continuous dischargeability and light-blocking properties.

[0200] The content of the sensitizer is preferably 1 part by mass or more and 70 parts by mass or less, more preferably 5 parts by mass or more and 50 parts by mass or less, and particularly preferably 10 parts by mass or more and 30 parts by mass or less, relative to 100 parts by mass of the acid generator. This is because the composition has an excellent balance between continuous dischargeability and light-blocking properties. In addition, the composition has excellent moist heat resistance.

[0201] 5. Solvent The composition may contain a solvent as needed. The solvent is a liquid at room temperature (25°C) under atmospheric pressure, capable of dispersing or dissolving each component in the composition, and does not react with the cationically polymerizable component due to the action of the acid generator. Therefore, the cationically polymerizable compounds described in the above section "1. Cationically polymerizable component" are not included in the above solvents, even if they are liquid at room temperature (25°C) and atmospheric pressure. Furthermore, since the solvent is used to disperse or dissolve each component of the composition, the dye described in "2. Black dye" above, the photoacid generator described in "3. Photoacid generator", the sensitizer described in "4. Sensitizer", etc. are not included in the solvent even if they are liquid at room temperature and atmospheric pressure.

[0202] As such a solvent, either water or an organic solvent can be used, but the organic solvent is preferably used.

[0203] Examples of the organic solvent include ketones such as methyl ethyl ketone, methyl amyl ketone, diethyl ketone, acetone, methyl isopropyl ketone, methyl isobutyl ketone, cyclohexanone, and 2-heptanone; ether-based solvents such as ethyl ether, dioxane, tetrahydrofuran, 1,2-dimethoxyethane, 1,2-diethoxyethane, and dipropylene glycol dimethyl ether; ester-based solvents such as methyl acetate, ethyl acetate, n-propyl acetate, isopropyl acetate, n-butyl acetate, cyclohexyl acetate, ethyl lactate, dimethyl succinate, and Texanol; cellosolve-based solvents such as ethylene glycol monomethyl ether and ethylene glycol monoethyl ether; alcohol-based solvents such as methanol, ethanol, iso- or n-propanol, iso- or n-butanol, amyl alcohol, and diacetone alcohol; ethylene glycol monomethyl acetate, ethylene glycol monoethyl acetate, propylene glycol-1-monomethyl ether-2-acetate (PGMEA), and dipropylene glycol monomethyl ether acetate. Ether ester solvents such as butyl acetate, 3-methoxybutyl acetate, ethoxyethyl propionate, 1-t-butoxy-2-propanol, 3-methoxybutyl acetate, and cyclohexanol acetate; aromatic solvents such as benzene, toluene, and xylene; aliphatic hydrocarbon solvents such as hexane, heptane, octane, and cyclohexane; terpene hydrocarbon oils such as turpentine oil, D-limonene, and pinene; mineral spirits, Swazol #310 (Cosmo Matsuyama Oil Co., Ltd.), and Solvesso #100 (Exxon Chemical Co., Ltd.). halogenated aliphatic hydrocarbon solvents such as carbon tetrachloride, chloroform, trichloroethylene, methylene chloride, 1,2-dichloroethane, etc.; halogenated aromatic hydrocarbon solvents such as chlorobenzene, etc.; carbitol-based solvents, aniline, triethylamine, pyridine, acetic acid, acetonitrile, carbon disulfide, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, dimethyl sulfoxide, water, etc., and these solvents can be used alone or in combination as a mixed solvent of two or more thereof.Among these, ketones, ether ester solvents, and the like, particularly propylene glycol-1-monomethyl ether-2-acetate, cyclohexanone, and the like can be mentioned, and these solvents can be used alone or as a mixed solvent of two or more kinds. Among the above organic solvents, ketones, alcohol-based solvents, ether ester-based solvents, aromatic solvents, etc. are preferred, and ether ester-based solvents and alcohol-based solvents are particularly preferred, because the composition has an excellent balance between continuous dischargeability and light-blocking properties, and also because the composition has excellent moist heat resistance.

[0204] The content of the solvent may be any content that provides an excellent balance between continuous dischargeability and light-shielding properties, and may be, for example, 1 part by mass or more and 99 parts by mass or less, and preferably 10 parts by mass or more and 90 parts by mass or less, per 100 parts by mass of the composition. The content of the solvent is more preferably 30 parts by mass or more and 80 parts by mass or less, per 100 parts by mass of the composition, in that this facilitates further improvement in continuous dischargeability, and is particularly preferably 40 parts by mass or more and 75 parts by mass or less. It is preferable that the content of the solvent is 50 parts by mass or less per 100 parts by mass of the composition, as this results in excellent ease of drying and provides greater freedom in selecting the destination for forming a cured film of the composition. In particular, it is preferable that the content of the solvent is 30 parts by mass or less, and particularly preferably 10 parts by mass or less.

[0205] 6. Additives The composition of the present disclosure contains a cationically polymerizable component, a black dye, and a photoacid generator, and further contains a sensitizer, a solvent, and the like, as necessary, but may also contain other components in addition to these. Other components include various additives such as inorganic fillers, organic fillers, silane coupling agents, antifoaming agents, thickeners, thixotropic agents, surfactants, leveling agents, dispersants, flame retardants, plasticizers, stabilizers, polymerization inhibitors, ultraviolet absorbers, antioxidants, antistatic agents, flow adjusters, and adhesion promoters.

[0206] The composition of the present disclosure preferably contains additives such as a leveling agent, a dispersant, and an antioxidant.

[0207] As the antioxidant, for example, a compound having a phenolic hydroxyl group can be preferably used. Specifically, the compound having a phenolic hydroxyl group used as an antioxidant is preferably a compound represented by the following formula, because the cured product of the composition has excellent light resistance.

[0208] [ka]

[0209] In the composition of the present disclosure, the amount of antioxidant is typically preferably 0.02 to 10 parts by mass, and more preferably 0.1 to 5 parts by mass, per 100 parts by mass of the solid content of the composition. The total amount of leveling agent and dispersant is typically preferably 0.01 to 1 part by mass, and more preferably 0.01 to 0.5 parts by mass or less, per 100 parts by mass of the solid content of the composition.

[0210] In the composition of the present disclosure, the components other than the cationically polymerizable component, photoacid generator, sensitizer, and black dye (excluding the solvent and filler) are, for example, preferably 5 parts by mass or less per 100 parts by mass of the solid content of the composition of the present disclosure, in order to more easily obtain the effects of continuous dischargeability and light-blocking properties, and more preferably 1 part by mass or less. Furthermore, if the composition of the present disclosure contains a radically polymerizable component, the amount thereof is preferably 20 parts by mass or less per 100 parts by mass of the cationically polymerizable component, in order to more easily obtain the effects of continuous dischargeability and light-blocking properties, and more preferably 10 parts by mass or less.

[0211] 7. Composition The method for producing the composition may be any method that can form a composition containing the desired amounts of the above components, and examples thereof include methods that use known mixing means.

[0212] The applications of the composition preferably require excellent continuous discharge properties and light-shielding properties, and include, for example, optical filters including light-shielding filters, paints, coatings, linings, adhesives, printing plates, insulating varnishes, insulating sheets, laminates, printed circuit boards, sealants for semiconductor devices, LED packages, liquid crystal injection ports, organic electroluminescence (EL), optical elements, electrical insulation, electronic components, and separation membranes, molding materials, putties, glass fiber impregnation agents, fillers, passivation films for semiconductors and solar cells, interlayer insulating films, protective films, printed circuit boards, color televisions, PC monitors, personal digital assistants, color filters for CCD image sensors, electrode materials for plasma display panels, printing inks, dental compositions, resins for stereolithography, both liquid and dry films, micromachine parts, glass fiber cable coatings, and holographic recording materials.

[0213] In the present disclosure, the composition is preferably used as an optical filter, and more preferably as a light-shielding filter (ND filter) that reduces the transmittance of all visible light, and particularly preferably as a light-shielding film such as a black matrix used in an image display device; a color adjustment filter for an image display device; a light-shielding filter for improving antireflection properties, etc. This is because the composition can exhibit excellent light-shielding properties even in a thin film, and is particularly useful in the above-mentioned applications where thin films are highly required. In addition, in the present disclosure, the composition can also be preferably used as a solder resist for use in printed circuit boards, because it provides excellent protection for wiring. The composition may be used to achieve two purposes at the same time, for example, the thicker portion may be used as a black matrix or the like, and the thinner portion may be used as a color adjustment filter. In the light-shielding filter, reducing the transmittance of all visible light means, for example, that when a cured film of the composition is formed so as to have a transmittance of 45% at 500 nm, the transmittance at 400 nm and the transmittance at 600 nm are within the range of 40% to 50%. In the present disclosure, it is particularly preferable that the transmittance at 700 nm is also within the range of 40% to 50%.

[0214] Here, examples of the color adjustment filter include filters that adjust light of each color. More specifically, examples of the color adjustment filter include filters that are used as optical filters and are arranged so as to overlap with color filters in a planar view in order to further adjust the color of light transmitted through the color filters in which pixels of R (red), G (green), B (blue) and other colors are arranged, and filters that are arranged so as to overlap with light emitters of each color in a planar view in order to further adjust the color of light irradiated from light emitters of each color, such as electroluminescent elements of each color.

[0215] The material of the adherend on which the cured product of the composition is formed is not particularly limited, and commonly used materials can be used, for example, metal substrates such as aluminum, titanium, stainless steel, mild steel, plated steel, etc., inorganic materials such as glass, cellulose esters such as diacetyl cellulose, triacetyl cellulose (TAC), propionyl cellulose, butyryl cellulose, acetylpropionyl cellulose, nitrocellulose, etc., polyamides, polyimides, polyurethanes, epoxy resins, polycarbonates, polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, poly-1,4-cyclohexene, etc. Examples of polymeric materials include polyesters such as dimethylene terephthalate, polyethylene-1,2-diphenoxyethane-4,4'-dicarboxylate, and polybutylene terephthalate; polystyrene; polyolefins such as polyethylene, polypropylene, and polymethylpentene; vinyl compounds such as polyvinyl acetate, polyvinyl chloride, and polyvinyl fluoride; acrylic resins such as polymethyl methacrylate and polyacrylate; polycarbonate; polysulfone; polyethersulfone; polyetherketone; polyetherimide; polyoxyethylene, norbornene resin, and cycloolefin polymer (COP). Furthermore, the adherend on which the cured product of the composition is formed may be, for example, the upper surface of pixels of a color filter when the cured product of the composition is used in a color adjustment filter or the like.

[0216] B. Cured product Next, the cured product of the present disclosure will be described. The cured product of the present disclosure is characterized by being a cured product of the above-described composition. The cured product is obtained by curing the above-mentioned composition, and therefore has excellent light-blocking properties. Furthermore, the composition has excellent continuous dischargeability, and is less likely to clog when discharged from a nozzle. Therefore, the cured product has excellent shape stability and productivity.

[0217] The cured product of the present disclosure uses the above-described composition. The cured product of the present disclosure will be described in detail below. The composition is the same as that described in the section "A. Composition" above.

[0218] The cured product generally contains a polymer of a cationically polymerizable component.

[0219] The planar shape, thickness, etc. of the cured product can be appropriately set depending on the intended use of the cured product, etc. The thickness can be, for example, 0.05 μm or more and 300 μm or less.

[0220] The total light transmittance and haze value of the cured product are appropriately set depending on the intended use of the cured product, and are adjusted by the thickness, concentration of the black dye, and the like.

[0221] The method for producing the cured product is not particularly limited as long as it is a method that can form the cured product of the composition into a desired shape. Such a production method is similar to that described in the section "C. Production method of the cured product" below, and therefore a detailed description thereof will be omitted here.

[0222] The uses of the cured product are the same as those described in the section "A. Composition" above.

[0223] C. Manufacturing method of cured product Next, a method for producing the cured product of the present disclosure will be described. The method for producing a cured product according to the present disclosure is characterized by including a step of curing the above-described composition.

[0224] According to the present disclosure, since the above-described composition is used, a cured product having excellent shape stability and light-blocking properties can be produced with good productivity.

[0225] The method for producing a cured product according to the present disclosure includes the curing step described above. Each step of the method for producing a cured product according to the present disclosure will be described in detail below. The composition is the same as that described in the above section "A. Composition," and therefore, a description thereof will be omitted here.

[0226] 1. Hardening process The curing step is a step of curing the above-mentioned composition. The method for curing the composition may be any method that can polymerize the cationically polymerizable components, and examples thereof include a method in which a coating film of the composition is irradiated with light (energy rays), because this method facilitates polymerization of the cationically polymerizable components.

[0227] In this step, the light source of the energy rays used for polymerizing the cationically polymerizable component can be high-energy rays such as electromagnetic wave energy having a wavelength of 2000 angstroms to 7000 angstroms, electron beams, X-rays, and radioactive rays obtained from ultra-high pressure mercury lamps, high pressure mercury lamps, medium pressure mercury lamps, low pressure mercury lamps, mercury vapor arc lamps, xenon arc lamps, carbon arc lamps, metal halide lamps, fluorescent lamps, tungsten lamps, excimer lamps, germicidal lamps, light-emitting diodes, CRT light sources, etc. Preferably, ultra-high pressure mercury lamps, mercury vapor arc lamps, carbon arc lamps, xenon arc lamps, light-emitting diodes, etc. that emit light with a wavelength of 300 to 450 nm are used, as this facilitates polymerization of the cationically polymerizable component.

[0228] The irradiation dose of the energy ray is not particularly limited and can be determined appropriately depending on the composition of the composition. From the viewpoint of preventing deterioration of the components in the composition, the irradiation dose is set to 100 mJ / cm at 365 nm. 2 ~4000mJ / cm 2 is preferred, and 100 mJ / cm 2 ~2000mJ / cm 2 is more preferred.

[0229] In this step, the curing method may be a method in which the energy ray irradiation method and the heating method are used in combination. In this case, it is preferable to perform the energy ray irradiation method and the heating method in this order, because this allows the polymerization of the cationically polymerizable component to proceed efficiently.

[0230] The coating film of the composition in this step can be heated using a hot plate or other heating means, an atmospheric oven, an inert gas oven, a vacuum oven, a hot air circulation oven, or the like. The heating temperature when heating the coating film is not particularly limited, but from the viewpoint of facilitating polymerization of the cationically polymerizable component, it is preferably 70°C or higher and 200°C or lower, and more preferably 90°C or higher and 150°C or lower. The heating time for heating the coating film is not particularly limited, but from the viewpoint of improving productivity, it is preferably 1 to 60 minutes, more preferably 1 to 30 minutes.

[0231] 2. Other processes The above manufacturing method may include other steps as required. Such a step may include a step of applying the composition before a step of curing the composition. The composition can be applied by any known method such as using a spin coater, roll coater, bar coater, die coater, curtain coater, various printing methods, or dipping. The substrate can be appropriately selected depending on the intended use of the cured product, and examples thereof include soda glass, quartz glass, semiconductor substrates, metals, paper, plastics, and the like. After being formed on a substrate, the cured product may be peeled off from the substrate and used, or may be transferred from the substrate to another adherend and used.

[0232] 3.Cured product The cured product produced by the production method of the present disclosure and its uses are the same as those described in the section "B. Cured product" above.

[0257] 2.Total light transmittance The compositions of the Examples and Comparative Examples were applied to a 10 cm x 10 cm glass substrate by spin coating to form a coating film (hereinafter, sometimes referred to as a pre-cured coating film). In addition, in the cases of Examples 30, 31, and 40 to 46 containing solvent J1 or J2, after coating, the solvent was dried and removed by heat treatment at 80° C. for 1 minute to form a coating film. Next, a UV-LED light source was used to illuminate the sample with 365 nm light at 3000 mJ / cm 2 Each composition was cured by irradiation to form a cured film. The cured film was then peeled off from the glass substrate to prepare a test film. The thickness of the coating film before curing was adjusted so that the coating film before curing had a transmittance of 45% at 550 nm. The total light transmittance of the obtained test film was measured using a haze meter (model number: NPH2000, manufactured by Nippon Denshoku Co., Ltd.) in accordance with JIS K7105 and JIS K7136, and evaluated according to the following evaluation criteria.

[0258] (Evaluation criteria for total light transmittance) ++: Total light transmittance is less than 50%. +: Total light transmittance is 50% or more and less than 70%. -: Total light transmittance is 70% or more. It can be determined that the lower the total light transmittance, the more excellent the light-shielding properties of the film obtained.

[0259] 3. Haze A test film was obtained in the same manner as in "2. Total light transmittance" above. The haze (haze value: %) of the obtained test film was measured in accordance with JIS K7105 and JIS K7136 using a haze meter (model number: NPH2000, manufactured by Nippon Denshoku Co., Ltd.), and evaluated according to the following evaluation criteria.

[0260] (Haze's evaluation criteria) ++: Haze value is less than 1%. +: Haze value is 1% or more and less than 5%. -: Haze value is 5% or more. It can be determined that the lower the haze value, the less scattering there is and the more excellent the light-shielding film that can be obtained.

[0261] 4. Moisture and heat resistance A cured film was formed on a glass substrate in the same manner as in "2. Total light transmittance" above, to obtain an evaluation sample (a laminate of a glass substrate and a cured film). The evaluation sample was left in a thermo-hygroscopic tester at 60°C and 90% RH for one week, and then the cured film surface of the evaluation sample was observed under a microscope. The percentage of the area covered with deposits derived from the colorant (black dye, black pigment) within a 1 cm × 1 cm area of ​​the cured film surface was measured and evaluated according to the following evaluation criteria.

[0262] <Evaluation criteria> ++: Less than 10% + : 10% or more but less than 30% - : 30% or more The small proportion of the area covered with precipitates derived from the colorant indicates that the colorant is stably retained in the cured product and that the change in light absorption of the cured product is small.
