Description

[Technical Field]

[0001] This invention relates to a coloring composition. Furthermore, this invention relates to a film, optical filter, solid-state image sensor, and image display device using a coloring composition. [Background technology]

[0002] Optical filters, such as color filters, are manufactured using a coloring composition that includes a coloring agent and a resin.

[0003] Furthermore, Example 2 of Patent Document 1 and Example 6 of Patent Document 2 describe forming the green pixels of a color filter using a coloring composition containing color index pigment green 36 and color index pigment yellow 155. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-260309 [Patent Document 2] Japanese Patent Application Publication No. 11-014825 [Overview of the project] [Problems that the invention aims to solve]

[0005] In recent years, there has been a growing demand for miniaturization and thinner films in solid-state image sensors. Therefore, thinner films containing colorants, such as color filters used in solid-state image sensors, are also desired. To achieve thinner films while maintaining the desired spectral performance, it is necessary to increase the concentration of the colorant in the coloring composition used for film formation.

[0006] However, as the concentration of the colorant in the total solid content of the colored composition increases, the proportion of components other than the colorant decreases relatively. As a result, the moisture resistance of the resulting film tends to decrease as the concentration of the colorant in the total solid content of the colored composition increases, and when the film is exposed to a high-humidity environment, the colorant tends to aggregate within the film, leading to the generation of foreign matter.

[0007] According to the inventors' research, it was found that the coloring compositions described in Patent Documents 1 and 2 have room for further improvement in terms of the moisture resistance of the films obtained using the coloring compositions.

[0008] Therefore, an object of the present invention is to provide a coloring composition that can form a film with excellent moisture resistance.

[Modes for carrying out the invention]

[0012] The details of the present invention will be described in detail below. In this specification, "~" is used to mean that the numbers before and after it include the lower and upper limits, respectively. In this specification, when groups (atomic groups) are not specified as substituted or unsubstituted, the notation includes both groups (atomic groups) with and without substituents. For example, "alkyl group" includes not only unsubstituted alkyl groups but also substituted alkyl groups. In this specification, "exposure" includes not only exposure using light but also drawing using particle beams such as electron beams and ion beams, unless otherwise specified. Examples of light used for exposure include the emission spectrum of mercury lamps, far ultraviolet light represented by excimer lasers, extreme ultraviolet (EUV) light, X-rays, electron beams, and other active light or radiation.

In this specification, the term "process" includes not only independent processes but also any process that is not clearly distinguishable from other processes, as long as its intended function is achieved.

[0013] <Coloring composition> A first aspect of the colored composition of the present invention is A coloring composition comprising a coloring agent and a resin, The above coloring agent contains Color Index Pigment Yellow 155. The above coloring composition is characterized in that the content of Color Index Pigment Yellow 155 in the total solid content is 16% by mass or more.

[0186] 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.

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.

[0228] 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.

[0229] 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.

[0230] 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.

[0231] 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.

[0232] <<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.

[0233] <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.

[0234] 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.

[0235] 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.

[0236] 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. (DFA4201NIEY, DFA4201NAEY, DFA4201J006P, etc.), Advantec Toyo Co., Ltd., Nippon Integris Co., Ltd. (formerly Nippon Microlith Co., Ltd.), and KITZ Microfilter Corporation can be used.

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.

[0238] 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.

[0239] <Membrane> The film of the present invention is a film 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. In particular, it can be preferably used as a colored pixel in a color filter. Examples of colored pixels include red pixels, green pixels, blue pixels, magenta pixels, cyan pixels, and yellow pixels, with red pixels, green pixels, and yellow pixels being preferred, red pixels or green pixels being more preferred, and green pixels being even more preferred.

The upper limit of the film thickness is more preferably 10 μm or less, even more preferably 5 μm or less, even more preferably 3 μm or less, and particularly preferably 1.5 μm or less. The lower limit of the film thickness is more preferably 0.2 μm or more, and even more preferably 0.3 μm or more.

[0241] <Memory manufacturing method> The film of the present invention can be manufactured by a step of applying the colored composition of the present invention to a support. 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.

[0242] 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.

[0243] 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.

[0244] Known methods can be used for applying the colored composition. Examples include the drop method (drop casting); 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 method, piezo method, thermal method), nozzle jet or other ejection system 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.

[0245] 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.

[0246] 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.

[0247] 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. Light sources with longer wavelengths of 300 nm or more can also be used.

[0248] 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).

[0249] 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.

[0250] 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.

[0251] 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 supply 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.

[0252] 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.

[0253] 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.

The Young's modulus of the pixels is preferably 0.5 to 20 GPa, and more preferably 2.5 to 15 GPa.

[0257] Each pixel in the optical filter preferably 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 lower limit, but it is preferably 0.1 nm or more. The surface roughness of the pixel can be measured using, for example, a Veeco AFM (atomic force microscope) Dimension3100. The water contact angle on the pixel can be set to a suitable 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·A (manufactured by Kyowa Interface Science Co., Ltd.). Furthermore, it is preferable that the volume resistivity of the pixel is high. Specifically, the volume resistivity of the pixel should be 10 9 It is preferable that it be Ω·cm or more, and 10 11 It is more preferable that it be Ω·cm or greater. There is no upper limit specified, but for example, 10 14 It is preferable that the resistance is Ω·cm or less. The volume resistivity of the pixel can be measured using an ultra-high resistance meter 5410 (manufactured by Advantest Corporation).

[0258] In optical filters, a protective layer may be provided on the surface of the film of the present invention. By providing a protective layer, various functions such as oxygen barrier, 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 protective layer-forming composition, 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.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] <Solid-state image sensor> The solid-state image sensor of the present invention includes the film of the present invention as described above. The configuration of the solid-state image sensor is not particularly limited as long as it functions as a solid-state image sensor, but for example, the following configuration can be given.

[0263] 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.

Details of the base layer composition will be described later. Next, the colored compositions of the examples and comparative examples were applied to the silicon wafer with the underlayer formed by spin coating so that the film thickness after deposition was 0.5 μm, and then heated at 100°C for 2 minutes using a hot plate. Then, using an i-line stepper exposure system FPA-3000i5+ (manufactured by Canon Corporation), exposure was performed at 200 mJ / cm² through a mask having a 1.0 μm island pattern. 2 The wafer was exposed to the specified exposure. Next, the silicon wafer was stored for 30 minutes at a temperature of 23°C and a humidity of 50%, and then paddle-developed for 60 seconds at 23°C using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH). After that, it was rinsed with a spin shower, then washed with pure water, and finally heated on a hot plate at 220°C for 5 minutes to form island pattern pixels. For silicon wafers with island pattern pixels, propylene glycol monomethyl ether acetate was paddled for 5 minutes at a temperature of 23°C and a humidity of 50%. The propylene glycol monomethyl ether acetate on the pixels was then removed by spin-drying. Next, a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH) was used, and the wafers were paddled at 23°C for 60 seconds. After that, the wafers were rinsed with a spin shower, washed with pure water, and then heated on a hot plate at 220°C for 5 minutes. For silicon wafers with island pattern pixels formed after the above processing, a constant temperature and humidity test (held for 1000 hours in an environment of 85°C and 95% humidity) was performed. Thirty randomly selected pixels were observed with a scanning electron microscope (SEM) to check for the presence or absence of foreign matter in the pixels, and the humidity resistance was evaluated according to the following criteria. 5: No foreign matter was observed in any of the 30 pixels. 4. There were 1 to 3 pixels where foreign matter was found. 3. There were 4 to 10 pixels where foreign matter was found. 2. There were 11 to 20 pixels where foreign matter was found. 1: More than 21 pixels were found to contain foreign matter.
