[0138] <Composition>

[0139] The composition of the present invention is,

[0140] A near-infrared absorbing pigment having an inclusion compound structure a1 in which a compound represented by formula (1) or its geometric isomer is a guest and a cyclic compound that encloses the guest is a host, or an inclusion compound structure a2 in which a compound having a pigment structure derived from the compound represented by formula (1) or its geometric isomer is a guest and a cyclic compound that encloses the pigment structure of the guest is a host, and

[0141] Curable compounds and,

[0142] It is characterized by containing a solvent.

[0143] The composition of the present invention can form a film in which the occurrence of foreign matter defects is suppressed. The compound represented by formula (1) is A 1a and A 1ba. Since each is a group that independently appears as any one of formulas (A1) to (A5), it has multiple tetragonal or pentagonal structures. For this reason, there is a tendency for aggregation due to the interaction between the above structures in molecules. However, it is presumed that the near-infrared absorbing pigment used in the composition of the present invention, by having the aforementioned inclusion compound structure a1 or inclusion compound structure a2, causes the host cyclic compound region to undergo steric hindrance, thereby suppressing the aggregation of the guest compound represented by formula (1), its geometric isomer, or a compound having a pigment structure derived from the compound represented by formula (1) or its geometric isomer. For this reason, it is presumed that the composition of the present invention can form a film in which the occurrence of foreign matter defects is suppressed.

[0144] The composition of the present invention can be used as a composition for optical filters. Examples of types of optical filters include infrared blocking filters and infrared transmitting filters.

[0145] Hereinafter, each component used in the composition of the present invention will be described.

[0146] Specific near-infrared absorbing pigments

[0147] The composition of the present invention comprises a near-infrared absorbing pigment (hereinafter also referred to as a specific near-infrared absorbing pigment) having an inclusion compound structure a1 in which a compound represented by formula (1) or its geometric isomer is a guest and a cyclic compound that encloses the guest is a host, or an inclusion compound structure a2 in which a compound having a pigment structure derived from the compound represented by formula (1) or its geometric isomer is a guest and a cyclic compound that encloses the pigment structure of the guest is a host. This specific near-infrared absorbing pigment is also the near-infrared absorbing pigment of the present invention.

[0148] In this specification, cis-trans isomers may be cited as geometric isomers.

[0149] In this specification, the term "inclusion compound structure" means that the guest penetrates the space inside the ring of the cyclic compound forming the host and is integrated with the ring. That is, in the present invention, the specific near-infrared absorbing pigment is a guest, which is a compound represented by Formula (1) or a compound having a pigment structure derived from a compound represented by Formula (1), which penetrates the space inside the ring of the cyclic compound forming the host and is integrated with the ring. More specifically, when the guest is a compound represented by Formula (1), the compound represented by Formula (1) penetrates the space inside the ring of the cyclic compound forming the host and is integrated with the ring. Also, when the guest is a compound having a pigment structure derived from a compound represented by Formula (1), the pigment structure of the guest penetrates the space inside the ring of the cyclic compound forming the host and is integrated with the ring. In addition, whether a compound has an inclusion compound structure can be confirmed by combining measurement methods based on mass spectra, such as thin-layer chromatography and Maldi-tof-MS (Matrix Assisted Laser Desorption / Ionization Time-of-Flight Mass Spectrometry).

[0150] In the inclusion compound structure, the number of cyclic compounds forming the host is A in Equation (1). 1a and A 1b The number of cyclic compounds forming the host may be equal to or less than the sum of the structures. For the reason that the effect of the present invention is more significantly exhibited, the number of cyclic compounds forming the host is A in formula (1). 1a and A 1b It is desirable that the number of the sum of the structures be the same.

[0151] Certain near-infrared absorbing pigments may be pigments, dyes, or pigment derivatives.

[0152] The maximum absorption wavelength of a specific near-infrared absorbing pigment is preferably in the range of 800 to 1600 nm, more preferably in the range of 850 to 1400 nm, and more preferably in the range of 900 to 1200 nm.

[0153] It is preferable that a specific near-infrared absorbing pigment has a crosslinking group. According to this embodiment, a film can be formed in which the occurrence of thermal diffusion of the specific near-infrared absorbing pigment is further suppressed. Examples of crosslinking groups include (meth)acryloyl groups, (meth)acryloyloxy groups, (meth)acrylamide groups, styrene groups, maleimide groups, epoxy groups, oxetane groups, isocyanate groups, alkoxysilyl groups, and aryloxysilyl groups; it is preferable that the group be a (meth)acryloyloxy group, an epoxy group, an oxetane group, or an alkoxysilyl group, and more preferable that the group be a (meth)acryloyloxy group or an epoxy group.

[0154] When a specific near-infrared absorbing pigment has a crosslinking group, the crosslinking group may be present in either the guest or the host. If the guest has the crosslinking group, a membrane in which the occurrence of heat diffusion is more suppressed can be formed. If the host has the crosslinking group, a membrane with higher heat resistance can be formed.

Examples of cyclophenes include compounds in which the number of repetitions of the divalent aromatic hydrocarbon group and the divalent aliphatic hydrocarbon group is preferably 1 to 10, more preferably 1 to 6.

[0160] A calixarene refers to a compound in which a divalent aromatic hydrocarbon group having a phenolic hydroxyl group, such as a hydroxyphenyl group or a tert-butyl-hydroxyphenyl group, and a divalent aliphatic hydrocarbon group having an alkylene group (preferably an alkylene group having 1 to 5 carbon atoms) are alternately bonded to form a ring, and the methylene group included in the divalent aliphatic hydrocarbon group may be substituted with a sulfur atom or a -NH- group.

[0770] Method for manufacturing a membrane

[0771] The film of the present invention can be manufactured by undergoing a process of applying the composition of the present invention.

[0772] Examples of supports include those described above. As a method for applying the composition, known methods such as the spin coating method may be used. For example, the application method described in paragraph 0207 of International Publication No. 2022 / 085485 may be used.

[0773] The composition layer formed by applying the composition may be dried (pre-baked). When pre-baking is performed, the pre-baking temperature is preferably 150°C or lower, more preferably 120°C or lower, and more preferably 110°C or lower. The lower limit may be, for example, 50°C or higher, or 80°C or higher. The pre-baking time is preferably 10 seconds to 3000 seconds, more preferably 40 to 2500 seconds, and more preferably 80 to 220 seconds. Drying may be performed using a hot plate, an oven, etc.

[0774] The method for manufacturing the film may further include a process for forming a pattern. Examples of pattern forming methods include a pattern forming method using photolithography or a pattern forming method using dry etching, and a pattern forming method using photolithography is preferred. Furthermore, when the film of the present invention is used as a planar film, the process for forming a pattern is not required. The process for forming a pattern will be described in detail below.

[0775] (When forming a pattern using photolithography)

[0776] A method for forming a pattern using photolithography preferably includes a process of exposing a composition layer formed by applying the composition of the present invention to light in a pattern (exposure process), and a process of developing and removing the composition layer in an unexposed portion to form a pattern (development process). If necessary, a process of baking the developed pattern (post-bake process) may be provided. Each process is described below.

[0777] In the photolithography process, the composition layer is exposed in a pattern. For example, the composition layer can be exposed in a pattern by using a stepper exposure machine or a scanner exposure machine, etc., and exposing it through a mask having a predetermined mask pattern. By doing so, the exposed portion can be cured.

[0778] Examples of radiation (light) that can be used during exposure include g-lines and i-lines. In addition, light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) may be used. Examples of light with a wavelength of 300 nm or less include KrF-lines (wavelength 248 nm) and ArF-lines (wavelength 193 nm), and KrF-lines (wavelength 248 nm) are preferred. In addition, a light source with a long wavelength of 300 nm or more may also be used.

[0779] Additionally, during exposure, light may be irradiated continuously or pulsed (pulse exposure). Furthermore, pulse exposure is an exposure method in which light is irradiated and paused repeatedly in short cycles (e.g., at the millisecond level or less).

[0780] The irradiation dose (exposure dose) is, for example, 0.03 to 2.5 J / cm² 2 It is desirable, and 0.05~1.0 J / cm 2It is more preferable. The oxygen concentration during exposure can be appropriately selected, and in addition to performing the procedure under atmospheric conditions, exposure may be performed under a low-oxygen atmosphere where the oxygen concentration is, for example, 19 volume% or less (e.g., 15 volume%, 5 volume%, or substantially oxygen-free), or under a high-oxygen atmosphere where the oxygen concentration exceeds 21 volume% (e.g., 22 volume%, 30 volume%, or 50 volume%). Furthermore, the exposure intensity can be appropriately set, typically 1000 W / m² 2 ~100,000 W / m² 2 (For example, 5000W / m² 2 , 15000W / m 2 , or, 35,000W / m² 2 It can be selected from the range. Oxygen concentration and exposure illuminance may be appropriately combined; for example, oxygen concentration 10 volume% and illuminance 10,000 W / m² 2 , oxygen concentration 35 volume% and illuminance 20,000 W / m² 2 It can be done with the back.

[0781] Next, a pattern is formed by developing and removing the composition layer of the unexposed portion in the composition layer after exposure. The development and removal of the composition layer of the unexposed portion can be performed using a developer. As a result, the composition layer of the unexposed portion from the exposure process is dissolved into the developer, and only the photo-cured portion remains on the support. The temperature of the developer is, for example, preferably 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, to improve residue removal, the process of shaking off the developer every 60 seconds and supplying a fresh developer may be repeated several more times.

[0782] Examples of developing solutions include organic solvents and alkaline developing solutions, and alkaline developing solutions are preferably used. As for the developing solution and the cleaning (rinsing) method after development, the developing solution or cleaning method described in paragraph 0214 of International Publication No. 2022 / 085485 may be used.

[0783] After development and drying, it is preferable to perform additional exposure treatment or heat treatment (post-baking). Additional exposure treatment or post-baking is a curing treatment performed after development to ensure complete curing. For example, the heating temperature for post-baking is preferably 100 to 240°C, and more preferably 200 to 240°C. Post-baking can be performed on the film after development in a continuous or batch manner using heating means such as a hot plate, a convection oven (hot air circulating dryer), or a high-frequency heater to achieve the above conditions. When performing additional exposure treatment, it is preferable that the light used for exposure be light with a wavelength of 400 nm or less. In addition, the additional exposure treatment may be performed by the method described in Korean Published Patent Application No. 10-2017-0122130.

[0784] (When forming a pattern using the dry etching method)

[0785] Pattern formation using a dry etching method can be performed by a method such as forming a cured layer by curing a composition layer formed by applying the composition of the present invention onto a support, then forming a patterned photoresist layer on the cured layer, and then dry etching the cured layer using an etching gas with the patterned photoresist layer as a mask. In forming the photoresist layer, it is preferable to perform a pre-bake treatment. For pattern formation using a dry etching method, reference may be made to paragraphs 0010 to 0067 of Japanese Patent Publication No. 2013-064993, the contents of which are incorporated herein by reference.

The obtained composition layer was exposed to 1000 mJ / cm² using an i-line stepper exposure device FPA-3000i5+ (manufactured by Canon Inc.). 2 The entire surface is exposed with an exposure amount. Then, using a hot plate, the film is heated at 200°C for 5 minutes to produce a film with a thickness of 0.5 μm.

[0998] (Preparation Example 2) Method for preparing a membrane using the compositions of Examples 201–220 and Comparative Examples 2–3

[0999] Each composition is applied onto a glass substrate by spin coating, heated at 100°C for 2 minutes using a hot plate, and then heated at 200°C for 8 minutes to perform a curing treatment, thereby obtaining a film with a thickness of 0.5 μm.

[1000] <Evaluation of Foreign Matter Defect Inhibition>

[1001] Each composition (compositions of Examples 1 to 107, Examples 201 to 220, and Comparative Examples 1 to 3) is stored in a 45°C incubator for 3 days, and then a film is formed using each composition after storage by the above method. The obtained film is observed using a scanning electron microscope (measurement magnification = 10,000x), and the number of foreign substances present in a range of 10 μm × 15 μm is measured, and foreign substance defects are evaluated according to the following criteria.

The transmittance of the obtained film in the wavelength range of 700 to 1200 nm is measured using a spectrophotometer (U-4100, manufactured by Hitachi High-Tech Corp.), and the infrared shielding performance is evaluated according to the following criteria.

[1008] -metewand-

[1009] A: 1100nm < (wavelength at which the lowest transmittance occurs in the wavelength range of 700nm to 1200nm)

The transmittance of the obtained film in the wavelength range of 400 to 1200 nm is measured using a spectrophotometer (U-4100, manufactured by Hitachi High-Tech Corp.). Next, the film prepared above is left to stand for 1000 hours under constant temperature and humidity conditions of 85°C and 85%. The transmittance of the film after the moisture resistance test is measured, the maximum value of the change in transmittance is calculated, and the moisture resistance is evaluated according to the following criteria. The maximum value of the change in transmittance refers to the change in transmittance at the wavelength where the change in transmittance of the film in the wavelength range of 400 to 1200 nm is greatest before and after the moisture resistance test.

[1022] <Evaluation of Heat Diffusion Inhibition>

[1023] Each composition of Examples 1 to 107 and Comparative Example 1 is applied onto a glass wafer by a spin coating method so that the film thickness after application is 0.5 μm, and then a composition layer is formed by heating at 100°C for 2 minutes using a hot plate. Subsequently, regarding the obtained composition layer, an i-line stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Inc.) is used to expose the layer through a mask having a square pattern with a side length of 5.0 μm at 1000 mJ / cm² 2 The material is exposed to light with an exposure amount. Subsequently, a shower development was performed on the composition layer after exposure for 60 seconds at 23°C using a 0.3 mass% aqueous solution of tetramethylammonium hydroxide (TMAH) as a developer. Afterward, a spin shower was performed using pure water to form a square pattern (pixel 1) with a side length of 5 μm.

[1024] Next, a pattern (pixel 2) is formed on the missing portion of pixel 1 on a glass wafer on which pixel 1 is formed, using a thermal diffusion test composition in the same manner. For this pixel 2, the transmittance (spectral 1) in the range of wavelengths 700 to 1200 nm is measured using a microscopic system (LVmicro V, manufactured by Lambda Vision Co., Ltd.).

[1025] After that, the glass wafer on which pixel 1 and pixel 2 are formed is heated at 260°C for 5 minutes using a hot plate in an air atmosphere, and then the transmittance (spectral 2) in the range of wavelengths 700 to 1200 nm is measured for pixel 2 using a microscopic system (LVmicro V, manufactured by Lambda Vision Co., Ltd.).

[1026] The maximum value of the change in transmittance was determined using Spectrum 1 and Spectrum 2 of Pixel 2, and the heat diffusion suppression performance was evaluated according to the following criteria. The maximum value of the change in transmittance refers to the change in transmittance at the wavelength where the change in transmittance of Pixel 2 before and after heating is greatest in the range of wavelengths 700 to 1200 nm.
