Description

[Technical Field]

[0001] This invention relates to a colored composition containing a coloring agent. Furthermore, this invention relates to a film, optical filter, solid-state image sensor, and image display device using the colored composition. This invention also relates to azomethine metal complex compounds. [Background technology]

[0002] In recent years, the demand for solid-state image sensors, such as charge-coupled (CCD) image sensors, has grown significantly due to the widespread use of digital cameras and camera-equipped mobile phones. Color filters are used as key devices in displays and optical elements. Color filters typically have pixels for the three primary colors of red, green, and blue, and play the role of separating transmitted light into these three primary colors.

[0003] The colored pixels of each color filter are manufactured using a coloring composition containing a coloring agent. Patent Document 1 describes a pigment composition for color filters containing a phthalocyanine-based pigment and an azomethine copper complex-based pigment, wherein the mass ratio of the phthalocyanine-based pigment to the azomethine copper complex-based pigment is 99.9 / 0.1 to 96.5 / 3.5.

Examples of organic solvents include ester solvents, ketone solvents, alcohol solvents, amide solvents, ether solvents, and hydrocarbon solvents. For further details, please refer to paragraph 0223 of International Publication No. 2015 / 166779, which is incorporated herein by reference. In addition, ester solvents and ketone solvents substituted with cyclic alkyl groups can also be preferably used. Specific examples of organic solvents include polyethylene glycol monomethyl ether, dichloromethane, methyl 3-ethoxypropionate, ethyl 3-ethoxypropionate, ethyl cellosolve acetate, ethyl lactate, diethylene glycol dimethyl ether, butyl acetate, methyl 3-methoxypropionate, 2-heptanone, 2-pentanone, 3-pentanone, 4-heptanone, cyclohexanone, 2-methylcyclohexanone, 3-methylcyclohexanone, 4-methylcyclohexanone, cycloheptanone, cyclooctanone, cyclohexyl acetate, cyclopentanone, ethyl carbitol acetate, butyl carbitol acetate, propylene glycol monomethyl ether, propylene Examples include propylene glycol monomethyl ether acetate, 3-methoxy-N,N-dimethylpropanamide, 3-butoxy-N,N-dimethylpropanamide, propylene glycol diacetate, 3-methoxybutanol, methyl ethyl ketone, gamma butyrolactone, sulfolane, anisole, 1,4-diacetoxybutane, diethylene glycol monoethyl ether acetate, butane-1,3-diyl diacetate, dipropylene glycol methyl ether acetate, diacetone alcohol (also known as diacetone alcohol, 4-hydroxy-4-methyl-2-pentanone), 2-methoxypropyl acetate, 2-methoxy-1-propanol, and isopropyl alcohol.However, the amount of aromatic hydrocarbons used as organic solvents (benzene, toluene, xylene, ethylbenzene, etc.) may be reduced for environmental reasons (for example, it may be possible to reduce the amount to 50 ppm (parts per million) or less, 10 ppm or less, or 1 ppm or less relative to the total amount of organic solvent).

[0176] In the present invention, 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. (Chemical Daily, November 13, 2015).

[0177] Methods for removing impurities such as metals from organic solvents include, for example, distillation (molecular distillation, thin-film distillation, etc.) and filtration using filters. The pore size of the filter used for filtration is preferably 10 μm or less, more preferably 5 μm or less, and even more preferably 3 μm or less. The material of the filter is preferably polytetrafluoroethylene, polyethylene, or nylon.

[0178] Organic solvents may contain isomers (compounds with the same number of atoms but different structures). Furthermore, they may contain only one type of isomer or multiple types.

[0179] The peroxide content in the organic solvent is preferably 0.8 mmol / L or less, and more preferably substantially peroxide-free.

[0180] The solvent content in the colored composition is preferably 10 to 95% by mass, more preferably 20 to 90% by mass, and even more preferably 30 to 90% by mass.

[0181] Furthermore, from the viewpoint of environmental regulations, it is preferable that the coloring composition of the present invention substantially does not contain environmentally regulated substances. In this invention, substantially not containing environmentally regulated substances means that the content of environmentally regulated substances in the coloring composition is 50 ppm by mass or less, preferably 30 ppm by mass or less, more preferably 10 ppm by mass or less, and particularly preferably 1 ppm by mass or less. Examples of environmentally regulated substances include benzene; alkylbenzenes such as toluene and xylene; halogenated benzenes such as chlorobenzene. These are registered as environmentally regulated substances under the REACH (Registration Evaluation Authorization and Restriction of Chemicals) regulations, the PRTR (Pollutant Release and Transfer Register) law, VOC (Volatile Organic Compounds) regulations, etc., and their usage and handling methods are strictly regulated. These compounds may be used as solvents when manufacturing the various components used in the coloring composition, and may be mixed into the coloring composition as residual solvents. From the viewpoint of human safety and consideration for the environment, it is preferable to reduce these substances as much as possible. 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.

[0182] <<Infrared absorber>> The colored composition of the present invention may further contain an infrared absorbent. For example, when forming an infrared transmission filter using the colored composition of the present invention, the wavelength of light transmitted by the resulting film can be shifted to a longer wavelength side by including an infrared absorbent in the colored composition.

[0220] The coloring composition of the present invention preferably contains substantially no terephthalate esters. Here, "substantially free" means that the terephthalate ester content is 1000 ppb by mass or less of the total amount of the coloring composition, more preferably 100 ppb by mass or less, and particularly preferably zero.

[0221] From an environmental perspective, the use of perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts may be restricted. In the colored composition of the present invention, when the content of the above-mentioned compounds is reduced, the content of perfluoroalkyl sulfonic acid (particularly perfluoroalkyl sulfonic acid with 6 to 8 carbon atoms in the perfluoroalkyl group) and its salts, and perfluoroalkyl carboxylic acid (particularly perfluoroalkyl carboxylic acid with 6 to 8 carbon atoms in the perfluoroalkyl group) and its salts is preferably in the range of 0.01 ppb to 1,000 ppb, more preferably in the range of 0.05 ppb to 500 ppb, and even more preferably in the range of 0.1 ppb to 300 ppb, relative to the total solid content of the colored composition. The colored composition of the present invention may substantially not contain perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts. For example, a coloring composition substantially free of perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts, may be selected by using compounds that can substitute for perfluoroalkyl sulfonic acid and its salts, and compounds that can substitute for perfluoroalkyl carboxylic acid and its salts. Examples of compounds that can substitute for regulated compounds include compounds that have been excluded from regulation due to differences in the number of carbon atoms in the perfluoroalkyl group. However, the above does not preclude the use of perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts. The coloring composition of the present invention may contain perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts, to the maximum permissible extent.

[0222] The water content of the colored composition of the present invention is usually 3% by mass or less, preferably 0.01 to 1.5% by mass, and more preferably in the range of 0.1 to 1.0% by mass. The water content can be measured by the Karl Fischer method.

[0223] The colored composition of the present invention can be used by adjusting its viscosity for purposes such as adjusting the film surface (flatness, etc.) and adjusting the film thickness. The viscosity value can be appropriately selected as needed, but for example, 0.3 mPa·s to 50 mPa·s is preferred at 25°C, and 0.5 mPa·s to 20 mPa·s is more preferred. As a method for measuring viscosity, for example, a cone-plate type viscometer can be used and the measurement can be taken while the temperature has been adjusted to 25°C.

[0224] <<Container>> There are no particular limitations on the container used to house the colored composition, and any known container can be used. Furthermore, to suppress the incorporation of impurities into the raw materials and colored composition, it is preferable to use a multilayer bottle with an inner wall made of six types of resin in six layers, or a bottle with a seven-layer structure of six types of resin. Examples of such containers include the container described in Japanese Patent Application Publication No. 2015-123351. In addition, it is preferable to use glass or stainless steel for the inner wall of the container to prevent metal leaching from the inner wall, to improve the storage stability of the colored composition, and to suppress deterioration of its components.

[0225] <Method for preparing a colored composition> The colored composition of the present invention can be prepared by mixing the aforementioned components. When preparing the colored composition, all components may be dissolved and / or dispersed simultaneously in a solvent, or, if necessary, each component may be prepared as two or more solutions or dispersions and mixed at the time of use (application) to prepare the colored composition.

[0226] Furthermore, it is preferable that the preparation of the colored composition includes a process for dispersing the pigment. Examples of mechanical forces used for dispersing the pigment in this process include compression, squeezing, impact, shearing, and cavitation. Specific examples of these processes include bead mills, sand mills, roll mills, ball mills, paint shakers, microfluidizers, high-speed impellers, sand grinders, flow jet mixers, high-pressure wet atomization, and ultrasonic dispersion. In addition, when grinding pigments in a sand mill (bead mill), it is preferable to process under conditions that improve grinding efficiency, such as using beads with a small diameter or increasing the bead filling density. Furthermore, it is preferable to remove coarse particles after the grinding process by filtration, centrifugation, etc. Furthermore, for the process and disperser used to disperse the pigment, the processes and dispersers described in "Complete Collection of Dispersion Technology, published by Joho Kiko Co., Ltd., July 15, 2005," "Comprehensive Data Collection on Dispersion Technology and Practical Industrial Applications, Centered on Suspension (Solid / Liquid Dispersion Systems), published by Keiei Kaihatsu Center Publishing Department, October 10, 1978," and paragraph 0022 of Japanese Patent Publication No. 2015-157893 can be suitably used. In addition, in the process of dispersing the pigment, particle refinement treatment may be performed in a salt milling step. For materials, equipment, and processing conditions used in the salt milling step, for example, refer to the descriptions in Japanese Patent Publication No. 2015-194521 and Japanese Patent Publication No. 2012-046629.

[0227] In preparing a colored composition, it is preferable to filter the colored composition with a filter for purposes such as removing foreign matter and reducing defects. Any filter that has been conventionally used for filtration purposes can be used without particular limitations. For example, filters made of materials such as fluororesins such as polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF), polyamide resins such as nylon (e.g., nylon-6, nylon-6,6), and polyolefin resins such as polyethylene and polypropylene (PP) (including high-density and ultra-high molecular weight polyolefin resins) can be used. Among these materials, polypropylene (including high-density polypropylene) and nylon are preferred.

[0228] The pore size of the filter is preferably 0.01 to 7.0 μm, more preferably 0.01 to 3.0 μm, and even more preferably 0.05 to 0.5 μm. If the filter pore size is within the above range, fine foreign matter can be removed more reliably. The nominal value of the filter pore size can be referred to from the filter manufacturer. Various filters provided by Nippon Pall Co., Ltd. (DFA4201NXEY, DFA4201NAEY, DFA4201J006P, etc.), Advantec Toyo Co., Ltd., Nippon Integris Co., Ltd. (formerly Nippon Microlith Co., Ltd.), and KITZ Microfilter Corporation can be used.

[0229] Furthermore, it is also preferable to use fibrous filter media as a filter. Examples of fibrous filter media include polypropylene fiber, nylon fiber, and glass fiber. Commercially available products include the SBP type series (SBP008, etc.), TPR type series (TPR002, TPR005, etc.), and SHPX type series (SHPX003, etc.) from Rokitechno Co., Ltd.

[0230] When using filters, different filters (for example, a first filter and a second filter) may be combined. In this case, filtration with each filter may be performed only once or two or more times. Filters with different pore sizes within the range described above may also be combined. Furthermore, filtration with the first filter may be performed only on the dispersion, and then filtration with the second filter may be performed after mixing in other components. In addition, filters can be selected as appropriate according to the hydrophilicity and hydrophobicity of the composition.

[0231] <Membrane> The film of the present invention is obtained from the colored composition of the present invention described above. The film of the present invention can be used in optical filters such as color filters and infrared transmission filters.

[0232] The film thickness of the present invention can be appropriately adjusted depending on the purpose. For example, the film thickness is preferably 20 μm or less, more preferably 10 μm or less, and even more preferably 5 μm or less. The lower limit of the film thickness is preferably 0.1 μm or more, more preferably 0.2 μm or more, and even more preferably 0.3 μm or more.

[0233] When the film of the present invention is used as a color filter, it is preferable that the film has a hue of green, red, blue, cyan, magenta, or yellow, and more preferably that it has a hue of green, red, or yellow. Furthermore, the film of the present invention can be preferably used as a colored pixel of a color filter.

[0234] Furthermore, the film of the present invention preferably has a wavelength range of 470 to 520 nm at which the light transmittance is 50%, more preferably in the wavelength range of 475 to 520 nm, and even more preferably in the wavelength range of 480 to 520 nm. In particular, it is preferable that the wavelength at which the light transmittance is 50% exists in both the wavelength range of 470 to 520 nm and the wavelength range of 575 to 625 nm. In this embodiment, the short-wavelength wavelength at which the light transmittance is 50% is preferably in the wavelength range of 475 to 520 nm, and more preferably in the wavelength range of 480 to 520 nm. Also, the long-wavelength wavelength at which the light transmittance is 50% is preferably in the wavelength range of 580 to 620 nm, and more preferably in the wavelength range of 585 to 615 nm. A film having such spectral characteristics is preferably used as a green pixel.

[0236] <Memory manufacturing method> Next, a method for manufacturing the film of the present invention will be described. The film of the present invention can be manufactured by applying the coloring composition of the present invention. In the method for manufacturing the film, it is preferable to further include a step of forming a pattern (pixels). Examples of methods for forming the pattern (pixels) include photolithography and dry etching, with photolithography being preferred.

[0237] The photolithography method for pattern formation preferably includes the steps of forming a colored composition layer on a support using the colored composition of the present invention, 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). If necessary, a step of baking the colored composition layer (pre-bake step) and a step of baking the developed pattern (pixels) (post-bake step) may be provided.

[0238] In the step of forming the colored composition layer, the colored composition layer is formed on a support using the colored composition of the present invention. The support is not particularly limited and can be appropriately selected depending on the application. Examples include glass substrates and silicon substrates, with silicon substrates being preferred. A charge-coupled device (CCD), complementary metal-oxide-semiconductor (CMOS), transparent conductive film, etc., may be formed on the silicon substrate. A black matrix that isolates each pixel may also be formed on the silicon substrate. A base layer may be provided on the silicon substrate to improve adhesion with the upper layer, prevent diffusion of substances, or flatten the substrate surface. The base layer may be formed using a composition obtained by removing the colorant from the colored composition described herein, or a composition containing the resin, polymerizable compound, surfactant, etc., described herein. The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane. It is also preferably 30 to 80° when measured with water.

[0239] Known methods can be used for applying the colored composition. Examples include the drop casting method; slit coating method; spray method; roll coating method; spin coating method; casting method; slit and spin method; pre-wetting method (for example, the method described in Japanese Patent Application Publication No. 2009-145395); various printing methods such as inkjet (for example, on-demand, piezo, and thermal), nozzle jet printing, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing; transfer methods using molds, etc.; and nanoimprint methods. The application method using inkjet technology is not particularly limited and includes methods such as those described in "Expanding and Usable Inkjet Technology - Infinite Possibilities Seen in Patents," published February 2005 by Sumibe Techno Research (especially pages 115-133), as well as methods described in Japanese Patent Publication Nos. 2003-262716, 2003-185831, 2003-261827, 2012-126830, and 2006-169325. Furthermore, regarding the application method of the coloring composition, reference can be made to the descriptions in International Publication Nos. 2017 / 030174 and 2017 / 018419, and these contents are incorporated herein by reference.

[0240] The colored composition layer formed on the support may be dried (pre-baked). Pre-baking is not necessary when manufacturing the film by a low-temperature process. If pre-baking is performed, the pre-baking 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, and also 80°C or higher. The pre-baking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and even more preferably 80 to 220 seconds. Pre-baking can be performed using a hot plate, oven, etc.

[0241] Next, the colored composition layer is exposed in a pattern (exposure step). For example, the colored composition layer can be exposed in a pattern by using a stepper exposure machine or a scanner exposure machine to expose it through a mask having a predetermined mask pattern. This allows the exposed areas to be cured.

[0242] Examples of radiation (light) that can be used during exposure include g-rays and i-rays. Light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) 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.

[0243] 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).

[0244] The irradiation dose (exposure dose) is, for example, 0.03 to 2.5 J / cm². 2 Preferably, 0.05 to 1.0 J / cm² 2 This is more preferable. 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 1000 W / m². 2 ~100,000 W / m 2 (For example, 5000W / m 2 , 15000W / m 2 , or 35000W / 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. 2At an oxygen concentration of 35% by volume, the illuminance is 20,000 W / m². 2 This can be done as follows.

[0245] Next, the unexposed areas of the colored composition layer are developed and removed to form a pattern (pixels). 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 to 30°C. The development time is preferably 20 to 180 seconds. In addition, to improve the removal of residue, the developer may be emptied every 60 seconds, and the process of supplying fresh developer may be repeated several times.

[0246] Examples of developing solutions include organic solvents and alkaline developers, with alkaline developers being preferred. As the alkaline developer, an alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. Examples of alkaline agents include organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxyamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, pyrrole, piperidine, and 1,8-diazabicyclo-[5.4.0]-7-undecene, as well as inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, and sodium metasilicate. Alkaline agents with larger molecular weights are preferred from an environmental and safety perspective. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. The developer may also contain a surfactant. For convenience of transport and storage, the developer may be manufactured as a concentrated solution and then diluted to the required concentration at the time of use. The dilution ratio is not particularly limited, but can be set in the range of 1.5 to 100 times, for example. It is also preferable to wash (rinse) with pure water after development. It is preferable to perform rinsing by supplying the rinsing solution to the colored composition layer after development while rotating the support on which the colored composition layer has been formed after development. It is also preferable to move the nozzle that discharges the rinsing solution from the center of the support to the periphery of the support. In this case, when moving the nozzle from the center to the periphery of the support, the speed of movement of the nozzle may be gradually reduced. By performing rinsing in this manner, in-plane variation of the rinse can be suppressed. A similar effect can be obtained by gradually reducing the rotation speed of the support while moving the nozzle from the center to the periphery of the support.

[0247] After development and drying, it is preferable to perform additional exposure or heat treatment (post-bake). Additional exposure and post-bake are curing treatments after development to ensure complete hardening. The heating temperature in post-bake is preferably 100 to 240°C, and more preferably 200 to 240°C. Post-bake can be performed continuously or in batches using heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to achieve the above conditions. 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.

[0248] The dry etching method for pattern formation preferably includes the steps of: forming a colored composition layer on a support using the colored composition of the present invention; curing the entire colored composition layer to form a cured material layer; forming a photoresist layer on the cured material layer; exposing the photoresist layer in a patterned manner, then developing it to form a resist pattern; and using the resist pattern as a mask to dry etch the cured material layer using an etching gas. In the formation of the photoresist layer, it is preferable to further perform a pre-bake treatment. In particular, as a photoresist layer formation process, it is desirable to perform a heat treatment after exposure and a heat treatment after development (post-bake treatment). For the dry etching method for pattern formation, refer to paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, and this content is incorporated herein.

[0249] <Optical filters> The optical filter of the present invention has the film of the present invention described above. Examples of optical filters include color filters and infrared transmission filters, with color filters being preferred. In the case of color filters, it is preferable that the film of the present invention is used as the colored pixels of the color filter.

[0250] The optical filter may have a protective layer on the surface of the film of the present invention. By providing a protective layer, various functions such as oxygen blocking, low reflectivity, hydrophilicity, and shielding of light of specific wavelengths (ultraviolet rays, near-infrared rays, etc.) can be imparted. The thickness of the protective layer is preferably 0.01 to 10 μm, and more preferably 0.1 to 5 μm. Methods for forming the protective layer include applying a resin composition dissolved in an organic solvent, chemical vapor deposition, and attaching molded resin with an adhesive. The components constituting the protective layer include (meth)acrylic resin, ene-thiol resin, polycarbonate resin, polyether resin, polyarylate resin, polysulfone resin, polyethersulfone resin, polyphenylene resin, polyarylene etherphosphine oxide resin, polyimide resin, polyamide-imide resin, polyolefin resin, cyclic olefin resin, polyester resin, styrene resin, polyol resin, polyvinylidene chloride resin, melamine resin, urethane resin, aramid resin, polyamide resin, alkyd resin, epoxy resin, modified silicone resin, fluororesin, polycarbonate resin, polyacrylonitrile resin, cellulose resin, Si, C, W, Al2O3, Mo, SiO2, Si2N4, etc. Two or more of these components may be included. For example, in the case of a protective layer intended for oxygen barrier protection, the protective layer preferably contains polyol resin, SiO2, and Si2N4. In the case of a protective layer intended for low reflectivity, the protective layer preferably contains (meth)acrylic resin and fluororesin.

[0251] When forming a protective layer by coating a resin composition, known methods such as spin coating, casting, screen printing, and inkjet printing can be used as the coating method for the resin composition. The organic solvent contained in the resin composition can be a known organic solvent (for example, propylene glycol 1-monomethyl ether 2-acetate, cyclopentanone, ethyl lactate, etc.). When forming the protective layer by chemical vapor deposition, known chemical vapor deposition methods (thermochemical vapor deposition, plasma chemical vapor deposition, photochemical vapor deposition) can be used.

[0252] The protective layer may contain additives such as organic and inorganic fine particles, light absorbers of specific wavelengths (e.g., ultraviolet, near-infrared, etc.), refractive index adjusters, antioxidants, adhesives, and surfactants, as needed. Examples of organic and inorganic fine particles include polymer fine particles (e.g., silicone resin fine particles, polystyrene fine particles, melamine resin fine particles), titanium dioxide, zinc oxide, zirconium oxide, indium oxide, aluminum oxide, titanium nitride, titanium oxynitride, magnesium fluoride, hollow silica, silica, calcium carbonate, and barium sulfate. Known light absorbers can be used for light absorbers of specific wavelengths. The content of these additives can be adjusted as appropriate, but is preferably 0.1 to 70% by mass, and more preferably 1 to 60% by mass, relative to the total mass of the protective layer.

[0253] Furthermore, as the protective layer, the protective layer described in paragraphs 0073 to 0092 of Japanese Patent Publication No. 2017-151176 can also be used.

[0254] The optical filter may have a structure in which each pixel is embedded in a space partitioned, for example, in a grid pattern by a partition wall.

[0255] <Solid-state image sensor> The solid-state image sensor of the present invention has the film of the present invention described above. The configuration of the solid-state image sensor is not particularly limited as long as it has the film of the present invention and functions as a solid-state image sensor, but for example, the following configuration can be given.

[0256] The substrate has multiple photodiodes and transfer electrodes made of polysilicon or the like that constitute the light-receiving area of ​​a solid-state image sensor (CCD (charge-coupled device) image sensor, CMOS (complementary metal-oxide-semiconductor) image sensor, etc.), and a light-shielding film with an opening only for the light-receiving portion of the photodiode is provided on the photodiode and transfer electrodes, and a device protection film made of silicon nitride or the like is provided on the light-shielding film so as to cover the entire surface of the light-shielding film and the light-receiving portion of the photodiode, and a color filter is provided on the device protection film. Furthermore, the device may have a configuration in which a light-gathering means (e.g., a microlens; the same applies hereinafter) is provided on the device protection film and below the color filter (on the side closer to the substrate), or a configuration in which the light-gathering means is provided on the color filter. In addition, the color filter may have a structure in which each colored pixel is embedded in a space partitioned by partitions, for example in a grid pattern. In this case, it is preferable that the partitions have a lower refractive index than each colored pixel. Examples of imaging devices having such a structure include those described in Japanese Patent Publication No. 2012-227478, Japanese Patent Publication No. 2014-179577, and International Publication No. 2018 / 043654. Furthermore, as shown in Japanese Patent Publication No. 2019-211559, the light resistance may be improved by providing an ultraviolet absorption layer within the structure of the solid-state image sensor. The imaging device equipped with the solid-state image sensor of the present invention can be used not only in digital cameras and electronic devices with imaging functions (such as mobile phones), but also in in-vehicle cameras and surveillance cameras.
