[Technical Field]

[0001] This disclosure relates to colored compositions, films, color filters, solid-state image sensors, image display devices, and compounds. [Background technology]

[0002] Color filters are used as key devices in displays and optical elements. Color filters typically have pixels representing the three primary colors: red, green, and blue, and their role is to decompose transmitted light into these three primary colors. The colored pixels of each color filter are manufactured using coloring compositions.

[0003] Patent Document 1 describes the production of color filters and the like using a coloring composition comprising an isoindoline pigment such as Color Index Pigment Yellow 185, an isoindoline derivative having a barbituric acid structure, a resin, and a solvent.

Furthermore, the compound represented by formula (1) has a pyrazolidinedione skeleton (i.e., the skeleton in formula (1) that includes a five-membered ring with two nitrogen atoms). Due to these structures, the compound represented by formula (1) exhibits a yellow color. The compound represented by formula (1) of this disclosure comprises a five-membered ring having one nitrogen atom, a cyclic structure A, a pyrazolidinedione skeleton, and a linking group L. 1 amide group, and electron-withdrawing group R 3 It has these properties and is further in the form of dimers to tetramers. Therefore, it is presumed that, through the combination of these chemical structures, the compound represented by formula (1) in this disclosure forms numerous intramolecular and intermolecular hydrogen bonds, forming strong aggregates. Since the aggregates are stable to heat and light, a colored composition containing the compound represented by formula (1) can be used to obtain a film with excellent heat resistance and light resistance.

[0019] <Compound represented by formula (1)> The colored composition of this disclosure contains a compound represented by formula (1) (hereinafter also referred to as "the compound"). The compound is preferably a coloring agent.

[0020] [ka]

[0021] In formula (1), Each A independently represents a monocyclic structure with 5 or more members, or a polycyclic structure formed by the condensation of monocyclic structures with 5 or more members.

R 3 Each of these independently represents an electron-withdrawing group. L 1 This represents an n-valent linked group with 1 or more atoms. n represents an integer between 2 and 4.

[0022] (n) In formula (1), n ​​is an integer from 2 to 4, preferably 2 or 3, and more preferably 2, from the viewpoint of ease of synthesis of the compound, ease of hydrogen bond network formation, high heat resistance, high light resistance, and stability over time.

[0023] (L 1 ) As described above, in equation (1), n ​​is an integer between 2 and 4, preferably 2 or 3, and more preferably 2.

[0221] In this disclosure, it is preferable to use an organic solvent with a low metal content. The metal content of the organic solvent is preferably, for example, 10 ppb (parts per billion) or less by mass. If necessary, an organic solvent at the ppt (parts per trillion) level by mass may be used, and such organic solvents are provided, for example, by Toyo Gosei Co., Ltd.

These compounds may be used as solvents when manufacturing the various components used in the colored compositions, and may be mixed into the colored compositions as residual solvents. From the viewpoint of human safety and consideration for the environment, it is preferable to reduce these substances. One method for reducing environmentally regulated substances is to heat or reduce the pressure in the system to raise the temperature above the boiling point of the environmentally regulated substance and then distill it off. Furthermore, when distilling off small amounts of environmentally regulated substances, it is useful to azeotrope the solvent with a solvent having a similar boiling point to improve efficiency. In addition, if the mixture contains compounds with radical polymerization properties, polymerization inhibitors may be added during reduced-pressure distillation to suppress the progression of radical polymerization reactions and the resulting crosslinking between molecules. These distillation methods can be implemented at any stage, including the raw material stage, the product stage (e.g., the polymerized resin solution or polyfunctional monomer solution), or the stage of the colored composition prepared by mixing these compounds.

[0253] The film of this disclosure can be manufactured by a step of applying the colored composition of this disclosure to a support. The method for manufacturing the film preferably further includes a step of forming a pattern (pixels). Examples of methods for forming the pattern (pixels) include photolithography and dry etching, with photolithography being preferred.

[0254] The pattern formation by photolithography preferably includes the steps of forming a colored composition layer on a support using the colored composition of this disclosure, exposing the colored composition layer in a pattern, and developing and removing the unexposed parts of the colored composition layer to form a pattern (pixels).

This allows the exposed areas to be cured.

[0259] Examples of radiation (light) that can be used during exposure include g-rays, h-rays, and i-rays. 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), with KrF rays (wavelength 248 nm) being preferred. Long-wave light sources with wavelengths of 300 nm or more can also be used.

[0260] Furthermore, exposure may be performed by continuously irradiating with light, or by irradiating in pulses (pulsed exposure). Pulsed exposure is an exposure method that involves repeatedly irradiating and pausing with light in short cycles (for example, at the millisecond level or less).

The oxygen concentration during exposure can be appropriately selected. In addition to exposure in air, exposure may be carried out in a low-oxygen atmosphere with an oxygen concentration of 19 vol% or less (e.g., 15 vol%, 5 vol%, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration exceeding 21 vol% (e.g., 22 vol%, 30 vol%, or 50 vol%). Furthermore, the exposure intensity can be appropriately set, usually 1,000 W / m². 2 ~100,000W / m 2 (For example, 5,000 W / m 2 , 15000W / m 2 , or 35,000 W / m 2 The oxygen concentration and exposure intensity can be combined as appropriate; for example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m². 2 At an oxygen concentration of 35% by volume and an illuminance of 20,000 W / m² 2 It can be done in this way.

[0262] Next, the unexposed areas of the colored composition layer are developed and removed to form a pattern (pixel). The unexposed areas of the colored composition layer can be developed and removed using a developer. This causes the unexposed areas of the colored composition layer in the exposure process to dissolve in the developer, leaving only the photocured parts. The temperature of the developer is preferably, for example, 20°C to 30°C. The development time is preferably 20 seconds to 180 seconds. In addition, to improve the ability to remove residue, the developer may be emptied every 60 seconds, and the process of supplying fresh developer may be repeated several times.

When performing additional exposure, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure may also be performed using the method described in Korean Published Patent No. 10-2017-0122130.

The contact angle can be measured, for example, using a contact angle meter CV-DT-A (manufactured by Kyowa Interface Science Co., Ltd.). In addition, a high volume resistivity of the pixel is preferable.

[0374] ≪Rating≫ Each prepared colored composition was evaluated for the following items. The evaluation results are shown in Tables 5 to 11.

[0375] <Heat resistance> CT-4000 (manufactured by Fujifilm Electronic Materials Co., Ltd.) is applied to a glass substrate by spin coating to a thickness of 0.1 μm, and then heated on a hot plate at 220°C for 1 hour to form a base layer. Each coloring composition is then applied to this glass substrate with the base layer by spin coating, and then heated on a hot plate at 100°C for 2 minutes to obtain a coated film. The obtained coated film is irradiated with light of a wavelength of 365 nm at an exposure dose of 500 mJ / cm². 2 Exposure is performed. Next, a cured film with a thickness of 0.5 μm is obtained by heating it at 220°C for 5 minutes using a hot plate. The light transmittance (transmittance) in the range of 400 nm to 700 nm is measured on the obtained cured film using the instantaneous multi-photometric system MCPD-3000 manufactured by Otsuka Electronics Co., Ltd. Next, the cured film prepared above is heated at 265°C for 5 minutes. The transmittance of the cured film after heating is measured, the maximum value of the change in transmittance is determined, and the heat resistance is evaluated according to the following evaluation criteria. The transmittance was measured five times for each sample, and the average of the three results, excluding the maximum and minimum values, was adopted. The maximum change in transmittance refers to the change at the wavelength in the 400nm to 700nm range where the change in transmittance of the cured film before and after heating is greatest.

[0376] (Evaluation Criteria) A: The change in transmittance is less than 5%. B: The change in transmittance is 5% or more but less than 10%. C: The change in transmittance is 10% or more.

[0377] <Evaluation of lightfastness> Each colored composition, immediately after preparation, is applied to a soda glass sheet (75mm x 75mm square, 1.1mm thick) using a spin coater (H-360S, manufactured by Mikasa Corporation). Next, a coating film is obtained by pre-baking at 100°C for 2 minutes using a hot plate. The resulting coating film is then subjected to a high-pressure mercury lamp (USH-500BY, manufactured by Ushio Inc.) at a pressure of 1000 mJ / cm². 2 The film is exposed to light at the specified exposure level. Subsequently, the exposed coated film is heated on a hot plate in an air atmosphere at 200°C for 5 minutes to obtain a film with a thickness of 0.5 μm. The light transmittance (transmittance) of the obtained film in the range of 400 nm to 700 nm is measured using an MCPD-3000 manufactured by Otsuka Electronics Co., Ltd. Next, a UV cut filter (KU-1000100 manufactured by AS ONE Corporation) is attached to the film prepared above, and a lightfastness test is performed by irradiating it with 5 million lxh of light for 50 hours using a lightfastness tester (Xenon Weather Meter SX75 manufactured by Suga Test Instruments Co., Ltd.). The temperature inside the test apparatus is set to 63°C. The relative humidity inside the test apparatus is set to 50%. After the lightfastness test, the transmittance of the film is measured, the maximum value of the change in transmittance is determined, and the lightfastness is evaluated according to the following criteria. The transmittance is measured five times for each sample, and the average of the three results (excluding the maximum and minimum values) is used. The maximum change in transmittance refers to the change at the wavelength where the change in transmittance is greatest in the wavelength range of 400 nm to 700 nm for the film before and after the lightfastness test.

[0378] (Evaluation Criteria) A: The change in transmittance is less than 5%. B: The change in transmittance is 5% or more but less than 10%. C: The change in transmittance is 10% or more.

[0379] As shown above, Examples 1 to 93 are coloring compositions that yield films with high heat resistance and high light resistance. Furthermore, dispersions G1 to G67, Y1, and R1 to R6 also exhibit excellent stability over time.
