[0001] The present disclosure relates to a colored composition, a film, a color filter, a solid-state imaging device, an image display device, and a compound.

[0002] 2. Description of the Related Art Colorants are used in optical filters such as color filters. Conventionally, various colorants with different characteristics have been developed for different purposes.

[0003] For example, JP-A-52-083363 describes a yellowish orange pigment having an isoindoline skeleton and an indandione acidic nucleus, and states that the yellowish orange pigment is a vivid yellowish orange pigment that has lightfastness.

[0004] JP 2020-26503 A describes a pigment having an isoindoline skeleton and a barbituric acid nucleus.

[0013] The contents of the present disclosure are described in detail below. The following description of the constituent elements may be based on representative embodiments of the present disclosure, but the present disclosure is not limited to such embodiments. In this disclosure, the term "to" is used to mean that the numerical values ​​before and after it are included as upper and lower limits. In the numerical ranges described in stages in this disclosure, the upper or lower limit of one numerical range may be replaced with the upper or lower limit of another numerical range. Furthermore, in the numerical ranges described in the present text, the upper or lower limit of that numerical range may be replaced with a value shown in the examples. In this disclosure, when multiple substances corresponding to each component are present in the composition, the content of each component refers to the total content of the multiple substances present in the composition, unless otherwise specified. In the description of groups (atomic groups) in this disclosure, a notation that does not specify whether they are substituted or unsubstituted encompasses both unsubstituted groups (atomic groups) and substituted groups (atomic groups). For example, the term "alkyl group" encompasses not only unsubstituted alkyl groups (unsubstituted alkyl groups) but also substituted alkyl groups (substituted alkyl groups). In this disclosure, unless otherwise specified, "exposure" includes not only exposure using light but also drawing using particle beams such as electron beams and ion beams. Examples of light used for exposure include the bright line spectrum of a mercury lamp, far ultraviolet light typified by excimer lasers, extreme ultraviolet light (EUV light), X-rays, and actinic rays or radiation such as electron beams. In this disclosure, "(meth)acrylate" refers to both or either acrylate and methacrylate, "(meth)acrylic" refers to both or either acrylic and methacrylic, and "(meth)acryloyl" refers to both or either acryloyl and methacryloyl. In this disclosure, the weight-average molecular weight and number-average molecular weight are polystyrene-equivalent values ​​measured by GPC (gel permeation chromatography). In this disclosure, the term "total solids content" refers to the total mass of all components of a composition excluding the solvent. In this disclosure, the term "pigment" refers to a colorant that is poorly soluble in a solvent.In the present disclosure, the term "process" includes not only an independent process but also a process that cannot be clearly distinguished from other processes, as long as the intended effect of the process is achieved. In the present disclosure, with respect to an oxime compound that has E- and Z-stereoisomers, either the E- or Z-form may be used unless otherwise specified.

[0014] <Coloring Composition> The coloring composition of the present disclosure contains a colorant represented by the following formula 1, a resin, and a solvent.

[0015]

[0016] In Formula 1, A and B each independently represent a monocyclic structure or a polycyclic structure having five or more members; １ represents an n-valent linking group, and n represents an integer of 2 or more.

[0017] The coloring composition of the present disclosure contains a colorant represented by Formula 1, a resin, and a solvent, thereby providing a color filter with high heat resistance and low thermal diffusion to other pixels. The function of the coloring composition of the present disclosure is unclear, but is presumed to be as follows. The colorant represented by Formula 1 contains a five-membered ring containing a nitrogen atom and a cyclic structure A adjacent to the five-membered ring (i.e., a monocyclic or polycyclic structure of five or more members represented by A), and this structure gives the colorant a yellow color. Furthermore, the colorant represented by Formula 1 contains a five-membered ring having two oxygen atoms and a cyclic structure B adjacent to the five-membered ring (i.e., a monocyclic or polycyclic structure of five or more members represented by B), and this structure gives the colorant excellent color value. On the other hand, the colorant having cyclic structures A and B of the present disclosure, as described in JP-A-52-083363, had insufficient heat resistance and presented problems with thermal diffusion to other pixels. It is speculated that the colorant of the present disclosure has, in addition to the cyclic structures A and B, numerous substituents capable of hydrogen bonding, and thus forms an aggregate in which intermolecular interactions due to hydrogen bonding or the like act strongly. In other words, the aggregated colorant is stable against heat, and therefore a color filter having high heat resistance and low thermal diffusion to other pixels can be obtained by using a coloring composition containing the colorant of the present disclosure. It should be noted that the present disclosure is in no way limited to the above speculated mechanism.

[0018] <Colorant> In the present disclosure, the colored composition contains a colorant represented by the following formula 1.

These compounds may be used as solvents when producing each component used in the coloring composition, and may be mixed into the coloring composition as a residual solvent. From the viewpoint of human safety and environmental considerations, it is preferable to reduce these substances as much as possible. Examples of methods for reducing environmentally restricted substances include a method in which the system is heated or depressurized to a temperature above the boiling point of the environmentally restricted substance, thereby distilling off the environmentally restricted substance from the system. Furthermore, when distilling off a small amount of environmentally regulated substances, it is useful to perform azeotropy with a solvent having a boiling point equivalent to that of the solvent in question in order to increase efficiency. Furthermore, when a radically polymerizable compound is contained, a polymerization inhibitor or the like may be added and then distilled off under reduced pressure in order to prevent intermolecular crosslinking caused by the progress of a radical polymerization reaction during distillation under reduced pressure. These distillation methods can be used at any stage, such as the stage of raw materials, the stage of a product obtained by reacting the raw materials (for example, a resin solution or a polyfunctional monomer solution after polymerization), or the stage of a colored composition prepared by mixing these compounds.

The silicon substrate may also be formed with a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), a transparent conductive film, or the like. A black matrix is ​​also sometimes formed on the silicon substrate to isolate each pixel. The silicon substrate may also be provided with an underlayer to improve adhesion to an upper layer, prevent diffusion of substances, or flatten the substrate surface. The underlayer may be formed using a composition obtained by removing the colorant from the coloring composition described in the present disclosure, or a composition containing the resin, polymerizable compound, surfactant, or the like described in the present disclosure. The surface contact angle of the underlayer is preferably 20° to 70° when measured with diiodomethane. It is also preferably 30° to 80° when measured with water.

[0208] The coloring composition can be applied by any known method, for example, the method described in paragraph 0207 of WO 2022 / 085485.

[0209] The colored composition layer formed on the support may be dried (prebaked). When a film is produced by a low-temperature process, prebaking may not be performed. When prebaking is performed, the prebaking temperature is preferably 150°C or lower, more preferably 120°C or lower, and even more preferably 110°C or lower. The lower limit can be, for example, 50°C or higher, or can also be 80°C or higher. The prebaking time is preferably 10 seconds to 300 seconds, more preferably 40 seconds to 250 seconds, and even more preferably 80 seconds to 220 seconds. Prebaking can be performed using a hot plate, an oven, or the like.

[0210] Next, the coloring composition layer is exposed to light in a pattern (exposure step). For example, the coloring composition layer can be exposed to light in a pattern by using a stepper exposure machine, a scanner exposure machine, or the like, through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.

[0211] Examples of radiation (light) that can be used for exposure include g-line, h-line, and i-line. 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 line (wavelength 248 nm) and ArF line (wavelength 193 nm), with KrF line (wavelength 248 nm) being preferred. Long-wave light sources of 300 nm or more can also be used.

[0212] The exposure may be performed by continuous irradiation with light or by pulsed irradiation (pulse exposure), which is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, milliseconds or less).

[0213] The irradiation amount (exposure amount) is, for example, 0.03 J / cm ２ ~2.5 J / cm ２ is preferred, and 0.05 J / cm ２ ~1.0 J / cm ２ The oxygen concentration during exposure can be appropriately selected. In addition to being performed in the atmosphere, exposure may be performed in a low-oxygen atmosphere with an oxygen concentration of 19% by volume or less (e.g., 15% by volume, 5% by volume, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration of more than 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). The exposure illuminance can be appropriately set, and is usually 1000 W / m ２ ~100000W / m ２ (For example, 5000 W / m ２ , 15000W / m ２ , or 35,000 W / m ２ The oxygen concentration and exposure illuminance may be appropriately combined. For example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m ２ , oxygen concentration 35% by volume, illuminance 20,000 W / m ２ etc.

[0214] Next, the unexposed portions of the coloring composition layer are developed and removed to form a pattern (pixels). The unexposed portions of the coloring composition layer can be developed and removed using a developer. As a result, the unexposed portions of the coloring composition layer in the exposure step are dissolved into the developer, leaving only the photocured portions. 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 residue removability, the process of shaking off the developer every 60 seconds and then supplying fresh developer may be repeated several times.

[0215] Examples of the developer include organic solvents and alkaline developers, and alkaline developers are preferably used. For example, the developer and development method described in paragraph 0214 of WO 2022 / 085485 can also be used.

[0216] After development and drying, it is preferable to perform additional exposure treatment or heating treatment (post-baking). The additional exposure treatment or post-baking is a post-development curing treatment to ensure complete curing. The heating temperature in post-baking is, for example, preferably 100°C to 240°C, more preferably 200°C to 240°C. Post-baking can be performed continuously or batchwise using a heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to achieve the above conditions for the developed film. When additional exposure treatment is performed, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure treatment may also be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

[0217] For pattern formation by dry etching, the method described in paragraph 0216 of WO 2022 / 085485 can also be used.

[0221] It is preferable that each pixel included in the color filter has high flatness. Specifically, the surface roughness Ra of the pixel is preferably 100 nm or less, more preferably 40 nm or less, and even more preferably 15 nm or less. There is no specified lower limit, but it is preferably 0.1 nm or more, for example. The surface roughness of the pixel can be measured using, for example, a Veeco Dimension 3100 AFM (atomic force microscope). The contact angle of water on the pixel can be set to an appropriate preferred value, but is typically in the range of 50° to 110°. The contact angle can be measured using, for example, a contact angle meter CV-DT Type A (Kyowa Interface Science Co., Ltd.). It is also preferable that the volume resistance of the pixel is high. Specifically, the volume resistance of the pixel is 10 ９ It is preferable that the resistance is Ω·cm or more, and 10 １１ It is more preferable that the resistivity is Ω·cm or more. １４ The volume resistivity of the pixel can be measured using an Ultra High Resistance Meter 5410 (manufactured by Advantest Corporation).

[0322] <Evaluation> Each of the prepared colored compositions was evaluated for the following items. The evaluation results are shown in Tables 5 to 10.

[0323] <Heat Resistance> CT-4000 (manufactured by FUJIFILM Electronic Materials Co., Ltd.) was applied to a glass substrate by spin coating so as to give a film thickness of 0.1 μm, and heated using a hot plate at 220° C. for 1 hour to form an underlayer. Each coloring composition was applied to the glass substrate with the underlayer by spin coating, and then heated using a hot plate at 100° C. for 2 minutes to obtain a coating film. The obtained coating film was irradiated with light having a wavelength of 365 nm at an exposure dose of 500 mJ / cm. ２ The film was then exposed to light at 220°C for 5 minutes using a hot plate to obtain a cured film with a film thickness of 0.5 μm. The light transmittance (transmittance) of the obtained cured film was measured in the range of 400 to 700 nm using an instantaneous multi-photometer MCPD-3000 manufactured by Otsuka Electronics Co., Ltd. Next, the cured film prepared above was heated at 265°C for 5 minutes. The transmittance of the cured film after heating was measured, the maximum change in transmittance was determined, and the heat resistance was evaluated according to the following evaluation criteria. The transmittance measurement was performed five times for each sample, and the average of the three results excluding the maximum and minimum values ​​was used. The maximum change in transmittance refers to the change in the wavelength at which the change in transmittance of the cured film was greatest in the wavelength range of 400 to 700 nm before and after heating. In Table 10, * indicates that the transmittance was not measured.

[0324] (Evaluation Criteria) A: The amount of change in transmittance is less than 5%. B: The amount of change in transmittance is 5% or more and less than 10%. C: The amount of change in transmittance is 10% or more.

[0325] <Heat Diffusion Resistance> Each colored composition was applied by spin coating onto an 8-inch (203.2 mm) glass wafer with an undercoat layer so that the film thickness after post-baking would be 0.5 μm, and then heated at 100° C. for 2 minutes using a hot plate to obtain a colored composition layer. Next, this colored composition layer was exposed to 1000 mJ / cm using an i-line stepper exposure device (FPA-3000i5+, manufactured by Canon Inc.). ２The glass wafer was exposed to light at an exposure dose of 1000 W through a mask with a 5.0 μm square dot pattern. Next, the glass wafer on which the exposed colored composition layer had been formed was placed on the horizontal rotary table of a spin shower developer (DW-30 model, manufactured by Chemitronics Corporation), and puddle development was carried out at 23° C. for 60 seconds using a developer (a 60% diluted solution of CD-2000 (manufactured by Fujifilm Electronic Materials Co., Ltd.)). Thereafter, the glass wafer was fixed to the horizontal rotary table using a vacuum chuck system, and while rotating the glass wafer at a rotation speed of 50 rpm using a rotation device, pure water was supplied in the form of a shower from a spray nozzle from above the center of rotation to perform a rinse treatment, and then spray-dried. Furthermore, a heat treatment (post-bake) was carried out for 300 seconds using a hot plate at 200° C., thereby forming pixel 1. Next, pixel 2 was formed on the glass wafer on which pixel 1 had been formed, in the empty portion of pixel 1 on the glass wafer, using a colored composition for evaluating heat diffusion resistance, in the same manner as pixel 1. For this pixel 2, the transmittance (spectrum 1) in the wavelength range of 400 nm to 700 nm was measured using a microscope system (LVmicro V, manufactured by Lambda Vision Corporation). Thereafter, the glass wafer on which pixels 1 and 2 were formed was heated at 260°C for 5 minutes using a hot plate in an air atmosphere, and then the transmittance (spectrum 2) of pixel 2 in the wavelength range of 400 nm to 700 nm was measured using a microscope system (LVmicro V, manufactured by Lambda Vision Corporation). The maximum amount of change in transmittance for pixel 2 was determined using spectra 1 and 2, and the thermal diffusion resistance was evaluated according to the following criteria. The transmittance measurement was performed five times for each sample, and the average value of three results excluding the maximum and minimum values ​​was used. The maximum amount of change in transmittance refers to the amount of change at the wavelength at which the amount of change in transmittance for pixel 2 in the wavelength range of 400 to 700 nm was greatest before and after heating. The colored composition used to evaluate thermal diffusion resistance was blue colored composition 1 shown below.

[0326] (Evaluation Criteria) A: The maximum change in transmittance is less than 3%. B: The maximum change in transmittance is 3% or more and less than 5%. C: The maximum change in transmittance is 5% or more.

[0327] (Blue colored composition 1 for thermal diffusion evaluation) 118.5 parts by mass of C.I. Pigment Blue 15:6, 29.6 parts by mass of C.I. Pigment Violet 23, 51.9 parts by mass of dispersant D12, and 800 parts by mass of solvent S1 were mixed to obtain a mixed solution. The obtained mixed solution was subjected to a dispersion treatment using an Ultra Apex Mill (trade name) manufactured by Kotobuki Industries Co., Ltd. as a circulating dispersion device (bead mill), to obtain dispersion B1.
