Furthermore, in the present disclosure, when a plurality of substances corresponding to each component are present in the composition, the amount of each component in the composition means the total amount of the corresponding substances present in the composition, unless otherwise specified. In addition, in the description of groups (atomic groups) in the present disclosure, descriptions that do not indicate whether they are substituted or unsubstituted include those that have no substituents as well as those that have a substituent. For example, an "alkyl group" includes not only an alkyl group that has no substituents (unsubstituted alkyl groups) but also an alkyl group that has a substituent (substituted alkyl groups). In this disclosure, unless otherwise specified, "Me" represents a methyl group, "Et" represents an ethyl group, "Pr" represents a propyl group, "Bu" represents a butyl group, and "Ph" represents a phenyl group. In the present disclosure, "(meth)acrylic" is a term used as a concept that includes both acrylic and methacrylic, and "(meth)acryloyl" is a term used as a concept that includes both acryloyl and methacryloyl. In addition, in the present disclosure, the term "process" refers not only to an independent process, but also to a process that cannot be clearly distinguished from other processes, as long as the intended purpose of the process is achieved. In the present disclosure, the term "total solid content" refers to the total mass of the components excluding the solvent from the entire composition of the composition. Also, as described above, the term "solid content" refers to the components excluding the solvent, and may be, for example, solid or liquid at 25°C. In the present disclosure, "mass %" and "weight %" are synonymous, and "parts by mass" and "parts by weight" are synonymous. Furthermore, in the present disclosure, combinations of two or more preferred embodiments are more preferred embodiments. In addition, unless otherwise specified, the weight average molecular weight (Mw) and number average molecular weight (Mn) in the present disclosure are molecular weights detected by a gel permeation chromatography (GPC) analyzer using columns of TSKgel GMHxL, TSKgel G4000HxL, or TSKgel G2000HxL (all product names manufactured by Tosoh Corporation) in a solvent of THF (tetrahydrofuran) and a differential refractometer, and converted using polystyrene as a standard substance. In this specification, a pigment means a compound that is poorly soluble in a solvent. In this specification, a dye means a compound that is easily soluble in a solvent. The present disclosure will be described in detail below.
[0016] (Colored photosensitive composition) The colored photosensitive composition according to the present disclosure contains a pigment and a diketopyrrolopyrrole compound A represented by the following formula 1, and the molar content of the diketopyrrolopyrrole compound A represented by the following formula 1 in the colored photosensitive composition is m A The molar content of the diketopyrrolopyrrole compound B represented by the following formula 1 is m B In this case, m A / (m A +m B ) is 10 mol % to 100 mol %, and the content of the pigment is 35 mass % or more based on the total solid content in the colored photosensitive composition.
[0017] [ka]
[0018] In formula 1, Diketopyrrolopyrrole Compound A:A 1 represents a monovalent organic group having an acidic or basic functional group; B 1 represents a monovalent organic group having no acidic functional group or basic functional group, and each R independently represents a hydrogen atom or a monovalent substituent. Diketopyrrolopyrrole Compound B:A 1 and B. 1represents a monovalent organic group having an acidic or basic functional group; A 1 and B 1 may be the same or different, and each R independently represents a hydrogen atom or a monovalent substituent.
[0019] In recent years, the number of pixels in image sensors has increased, and patterns have become finer and thinner. Accordingly, the pigment concentration in color filters has been relatively increased, and the amount of curable components has been reduced. As a result of detailed studies, the present inventors have found that in conventional colored photosensitive compositions in which the pigment content is 35 mass % or more relative to the total solid content in the colored photosensitive composition, the adhesiveness of the resulting cured product to a substrate or the like may be insufficient. As a result of extensive investigations, the present inventors have found that by employing the above-mentioned configuration, the resulting cured product has excellent adhesion. The content of the pigment is 35% by mass or more based on the total solid content in the colored photosensitive composition, and the colored photosensitive composition contains the diketopyrrolopyrrole compound A represented by the above formula 1, and the molar content of the diketopyrrolopyrrole compound A represented by the following formula 1 in the colored photosensitive composition is m A The molar content of the diketopyrrolopyrrole compound B represented by the following formula 1 is m B In this case, m A / (m A +m B ) is 10 mol % to 100 mol %, even in the case of a colored photosensitive composition having a high pigment concentration as described above, when the diketopyrrolopyrrole compound A is adsorbed on the pigment surface and a pigment particle-asymmetric diketopyrrolopyrrole compound A structure is formed, the acidic functional group or basic functional group is more likely to be arranged on the side opposite to the pigment side compared to a symmetric diketopyrrolopyrrole compound, and is more likely to interact with other components such as a dispersant. Thus, the diketopyrrolopyrrole ring structure provides excellent adsorption to the pigment, and the diketopyrrolopyrrole compound A is more likely to be arranged on the surface of the pigment particle, so that the pigment particle and the diketopyrrolopyrrole compound A can be easily arranged on the surface of the pigment particle. It is presumed that this improves the interaction between the diketopyrrolopyrrole compound A and the interaction between other components and the diketopyrrolopyrrole compound A, resulting in excellent adhesion of the obtained cured product (hereinafter also simply referred to as "adhesion").

[0089] The method for introducing an acidic functional group into the resin is not particularly limited, but may be, for example, the method described in Japanese Patent No. 6349629. Furthermore, examples of methods for introducing acidic functional groups into resins include a method in which an acid anhydride is reacted with a hydroxy group generated by a ring-opening reaction of an epoxy group in a dispersant (particularly a dispersant having an ethylenically unsaturated group) or an alkali-soluble resin to introduce an acid group.
[0090] In the present disclosure, it is preferable to use a resin having a basic functional group as the resin. According to this embodiment, the developability of the colored photosensitive composition can be improved, and pixels having excellent rectangularity can be easily formed. Examples of the basic functional group include an amino group and a heteroaryl group having a nitrogen atom, and an amino group is preferable, and a tertiary amino group is more preferable. The resin having a basic functional group can be used, for example, as an alkali-soluble resin.
[0091] The amine value of the resin having an amino group as a basic functional group is preferably 20 mgKOH / g to 200 mgKOH / g. The lower limit is more preferably 30 mgKOH / g or more, and particularly preferably 40 mgKOH / g or more.

[0092] The colored photosensitive composition according to the present disclosure may also contain a resin as a dispersant. Examples of dispersants include acidic dispersants (acidic resins) and basic dispersants (basic resins).

The acidic dispersant (acidic resin) is preferably a resin in which the amount of acidic functional groups is 70 mol% or more when the total amount of the amount of the acidic functional groups and the amount of the basic functional groups is 100 mol%, and more preferably a resin substantially composed of only acidic functional groups. The acidic functional groups of the acidic dispersant (acidic resin) are preferably carboxy groups. The acid value of the acidic dispersant (acidic resin) is preferably 30 mgKOH / g to 105 mgKOH / g, more preferably 40 mgKOH / g to 105 mgKOH / g, and even more preferably 50 mgKOH / g to 105 mgKOH / g.

The basic functional group of the basic dispersant is preferably an amino group.
[0093] The resin used as the dispersant preferably contains a repeating unit having an acidic functional group. By containing a repeating unit having an acidic functional group in the resin used as the dispersant, the generation of development residues can be further suppressed when forming a pattern by photolithography.
[0094] The resin used as the dispersant is preferably a graft resin. For details of the graft resin, refer to paragraphs 0025 to 0094 of JP2012-255128A, the contents of which are incorporated herein by reference.
[0095] The resin used as the dispersant is preferably a polyimine-based dispersant containing nitrogen atoms in at least one of the main chain and the side chain. The polyimine-based dispersant is preferably a resin having a main chain with a partial structure having a functional group with a pKa of 14 or less, a side chain with an atomic number of 40 to 10,000, and having a basic nitrogen atom in at least one of the main chain and the side chain. There is no particular limitation on the basic nitrogen atom as long as it is a nitrogen atom that exhibits basicity. For the polyimine-based dispersant, the description in paragraphs 0102 to 0166 of JP 2012-255128 A can be referred to, and the contents thereof are incorporated herein.
[0096] The resin used as the dispersant is preferably a resin having a structure in which a plurality of polymer chains are bonded to a core portion. Examples of such resins include dendrimers (including star-shaped polymers).

[0097] Moreover, the above-mentioned resin having an acidic functional group (alkali-soluble resin) can also be used as a dispersant.

[0099] As the dispersant, a resin having an aromatic carboxy group (hereinafter referred to as "resin B") is preferable. It is often mentioned. In the resin B, the aromatic carboxy group may be included in the main chain of the repeating unit, or may be included in the side chain of the repeating unit. For the reason that the developability and color fading are excellent, the aromatic carboxy group is preferably included in the main chain of the repeating unit. Although the details are unclear, it is presumed that the presence of the aromatic carboxy group near the main chain further improves these properties. In this specification, the aromatic carboxy group refers to a group having a structure in which one or more carboxyl groups are bonded to an aromatic ring. In the aromatic carboxy group, the number of carboxy groups bonded to the aromatic ring is preferably 1 to 4, and more preferably 1 to 2.

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. Although the lower limit is not specified, it is preferably 0.1 nm or more, for example. The surface roughness of the pixel can be measured, for example, using an AFM (atomic force microscope) Dimension3100 manufactured by Veeco. In addition, 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, for example, using a contact angle meter CV-DT·A type (manufactured by Kyowa Interface Science Co., Ltd.). In addition, the volume resistance value of the pixel is preferably high. Specifically, the volume resistance value of the pixel is 10 9 It is preferable that the resistance is Ω·cm or more. 0 11 It is more preferable that the resistivity is Ω·cm or more.

[0222] Furthermore, the color filter according to the present disclosure may have a protective layer on the surface of the film according to the present disclosure. By providing a protective layer, various functions such as oxygen blocking, low reflectance, hydrophilicity / hydrophobicity, and blocking of light of a specific wavelength (ultraviolet rays, near infrared rays, etc.) can be imparted. The thickness of the protective layer is preferably 0.01 μm to 10 μm, and more preferably 0.1 μm to 5 μm. Methods for forming the protective layer include a method of applying a resin composition dissolved in an organic solvent, a method of forming the protective layer by chemical vapor deposition, and the like. Examples of the protective layer include a method of bonding a molded resin with an adhesive, and a method of pasting a 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 ether phosphine oxide resin, polyimide resin, polyamideimide 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, fluorine resin, polycarbonate resin, polyacrylonitrile resin, cellulose resin, Si, C, W, Al2O3, Mo, SiO2, and Si2N4, and two or more of these components may be contained. For example, in the case of a protective layer intended for blocking oxygen, the protective layer preferably contains a polyol resin, SiO2, and Si2N4. In the case of a protective layer intended to reduce reflection, the protective layer preferably contains a (meth)acrylic resin and a fluorine resin.
[0223] When the protective layer is formed by applying a resin composition, known methods such as spin coating, casting, screen printing, and inkjet can be used as the method for applying the resin composition. Known organic solvents (e.g., propylene glycol 1-monomethyl ether 2-acetate, cyclopentanone, ethyl lactate, etc.) can be used as the organic solvent contained in the resin composition. When the protective layer is formed by chemical vapor deposition, known chemical vapor deposition methods (thermal chemical vapor deposition, plasma chemical vapor deposition, photochemical vapor deposition) can be used as the chemical vapor deposition.
[0224] The protective layer may contain additives such as organic particles, inorganic particles, absorbents of light of a specific wavelength (e.g., ultraviolet rays, near infrared rays, etc.), refractive index adjusters, antioxidants, adhesives, and surfactants, as necessary. Examples of organic particles and inorganic particles include polymer particles (e.g., silicone resin particles, polystyrene particles, melamine resin particles), titanium oxide, zinc oxide, zirconium oxide, indium oxide, aluminum oxide, titanium nitride, titanium oxynitride, magnesium fluoride, hollow silica, silica, calcium carbonate, and barium sulfate. Known absorbents can be used as absorbents of light of a specific wavelength. The content of these additives can be appropriately adjusted, but is preferably 0.1% by mass to 70% by mass, and more preferably 1% by mass to 60% by mass, based on the total mass of the protective layer.
[0225] In addition, as the protective layer, the protective layers described in paragraphs 0073 to 0092 of JP2017-151176A can also be used.
[0226] The color filter may have a base layer. The base layer may be formed, for example, using a composition obtained by removing the colorant from the coloring composition according to the present disclosure. The surface contact angle of the base layer is preferably 20° to 70° when measured with diiodomethane. Also, it is preferably 30° to 80° when measured with water. If the surface contact angle of the base layer is within the above range, the resin composition has good wettability. The surface contact angle of the base layer can be adjusted, for example, by adding a surfactant.
[0227] <Manufacturing method for color filters> Next, a method for producing a color filter using the colored photosensitive composition according to the present disclosure will be described. The color filter can be produced through a step of forming a colored photosensitive composition layer on a support using the colored photosensitive composition according to the present disclosure described above, and a step of forming a pattern on the colored photosensitive composition layer by a photolithography method or a dry etching method. The colored photosensitive composition according to the present disclosure can also suppress the generation of development residues, so it is particularly effective in the case of producing a color filter by forming a pattern on the colored photosensitive composition layer by a photolithography method.
[0228] -Photolithography method- First, a case of manufacturing a color filter by forming a pattern by photolithography will be described. This manufacturing method preferably includes a step of forming a colored photosensitive composition layer on a support using the colored photosensitive composition according to the present disclosure, a step of exposing the colored photosensitive composition layer in a pattern, and a step of developing and removing the unexposed part of the colored photosensitive composition layer to form a pattern (pixel). If necessary, a step of baking the colored photosensitive composition layer (pre-baking step) and a step of baking the developed pattern (pixel) (post-baking step) may be provided.
[0229] In the step of forming a colored photosensitive composition layer, a colored photosensitive composition layer is formed on a support using the colored photosensitive composition according to the present disclosure. The support is not particularly limited and can be appropriately selected depending on the application. For example, a glass substrate, a silicon substrate, etc. can be mentioned, and a silicon substrate is preferable. In addition, a charge-coupled device (CCD), a complementary metal oxide semiconductor (CMOS), a transparent conductive film, etc. may be formed on the silicon substrate. In addition, a black matrix that isolates each pixel may be formed on the silicon substrate. In addition, 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 photosensitive composition described herein, or a composition containing the resin, polymerizable compound, surfactant, etc. described herein.
[0230] The colored photosensitive composition can be applied by any known method, including, for example, a dropping method (drop casting), a slit coating method, a spray method, a roll coating method, a rotary coating method (spin coating), a casting coating method, a slit and spin method, a pre-wetting method (for example, a method described in JP-A-2009-145395), various printing methods such as ejection printing such as inkjet (for example, on-demand method, piezo method, thermal method) and nozzle jet, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing, a transfer method using a mold, and a nanoimprint method. The application method in inkjet is not particularly limited, and examples thereof include the method shown in "Expanding and Usable Inkjet - Infinite Possibilities Seen in Patents -, published in February 2005, Sumibe Techno Research" (particularly pages 115 to 133), and the methods described in JP 2003-262716 A, JP 2003-185831 A, JP 2003-261827 A, JP 2012-126830 A, JP 2006-169325 A, etc. In addition, for the application method of the colored photosensitive composition, the descriptions in WO 2017 / 030174 A and WO 2017 / 018419 A can be referred to, and the contents of these are incorporated herein.
[0231] The colored photosensitive composition layer formed on the support may be dried (prebaked). When the 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, and 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.
[0232] <<Exposure process>> Next, the colored photosensitive composition layer is exposed to light in a pattern (exposure step). For example, the colored photosensitive composition layer can be exposed to light in a pattern by using a stepper exposure machine or a scanner exposure machine through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.
[0233] Examples of radiation (light) that can be used for exposure include g-line and i-line. Light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 nm to 300 nm) 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 with wavelengths of 300 nm or more can also be used.
[0234] In addition, the exposure may be performed by irradiating the light continuously or by irradiating the light in pulses (pulse exposure). Pulse exposure is an exposure method in which light irradiation and pauses are repeated in a short cycle (for example, on the order of milliseconds or less).
[0235] The irradiation amount (exposure amount) is, for example, 0.03 J / cm 2 ~2.5J / cm 2 is preferred, and 0.05 J / cm 2 ~1.0J / cm 2 is more preferable. The oxygen concentration during exposure can be appropriately selected. In addition to exposure in air, exposure may be performed in a low-oxygen atmosphere with an oxygen concentration of 19 volume% or less (e.g., 15 volume%, 5 volume%, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration of more than 21 volume% (e.g., 22 volume%, 30 volume%, or 50 volume%). The exposure illuminance can be appropriately set, and is preferably 1,000 W / m 2 ~100,000W / m 2 (For example, 5,000 W / m 2 , 15,000W / m 2 , or 35,000 W / m 2The oxygen concentration and exposure illuminance may be appropriately combined. For example, the oxygen concentration is 10% by volume and the illuminance is 10,000 W / m 2 , oxygen concentration 35% by volume, illuminance 20,000 W / m 2 etc.
[0236] Next, the unexposed parts of the colored photosensitive composition layer are developed and removed to form a pattern (pixels). The unexposed parts of the colored composition layer can be developed and removed using a developer. As a result, the colored photosensitive composition layer in the unexposed parts in the exposure step is dissolved into the developer, and only the photocured parts remain. The developer is preferably an organic alkaline developer that does not cause damage to the underlying elements or circuits. 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 order to improve the removability of residues, the process of shaking off the developer every 60 seconds and supplying new developer may be repeated several times.
[0237] Examples of the developer include organic solvents and alkaline developers, and alkaline developers are preferably used. As the alkaline developer, an alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. Examples of the alkaline agent include organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxylamine, 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, and inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium hydrogencarbonate, sodium silicate, and sodium metasilicate. As the alkaline agent, compounds with a large molecular weight are preferred in terms of the environment and safety. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001% by mass to 10% by mass, more preferably 0.01% by mass to 1% by mass. The developer may further contain a surfactant. Examples of the surfactant include the above-mentioned surfactants, and nonionic surfactants are preferred. From the viewpoint of convenience of transportation and storage, the developer may be once produced as a concentrated solution and diluted to a required concentration when used. The dilution ratio is not particularly limited, but can be set, for example, in the range of 1.5 to 100 times. It is also preferred to wash (rinse) with pure water after development. Rinsing is performed by supplying a rinse liquid to the developed colored photosensitive composition layer while rotating the support on which the developed colored photosensitive composition layer is formed. It is also preferable to move the nozzle for ejecting the rinse liquid from the center of the support to the peripheral portion of the support. In this case, the nozzle may be moved while gradually decreasing the moving speed when moving the nozzle from the center of the support to the peripheral portion. By performing rinsing in this manner, the in-plane variation of the rinse can be suppressed. The same effect can also be obtained by gradually decreasing the rotation speed of the support while moving the nozzle from the center of the support to the peripheral portion.
[0238] After development and drying, it is preferable to perform additional exposure treatment or heating treatment (post-baking). Additional exposure treatment and post-baking are curing treatments after development to 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, a convection oven (hot air circulation dryer), or a high-frequency heater to heat the developed film to the above conditions. 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 be performed by the method described in Korean Patent Publication No. 10-2017-0122130.
[0239] -Dry etching method- Next, a case where a pattern is formed by a dry etching method to manufacture a color filter will be described. The pattern formation by the dry etching method preferably includes a step of forming a colored photosensitive composition layer on a support using the colored photosensitive composition according to the present disclosure, curing the entire colored photosensitive composition layer to form a cured layer, a step of forming a photoresist layer on the cured layer, a step of exposing the photoresist layer in a pattern shape and developing it to form a resist pattern, and a step of dry etching the cured layer using an etching gas with the resist pattern as a mask. In the formation of the photoresist layer, it is preferable to further perform a pre-bake treatment. In particular, as a process for forming the photoresist layer, a form in which a heat treatment after exposure and a heat treatment after development (post-bake treatment) are performed is desirable. For the pattern formation by the dry etching method, the description in paragraphs 0010 to 0067 of JP 2013-064993 A can be referred to, and the contents thereof are incorporated herein.
[0240] (Solid-state imaging element) The solid-state imaging device according to the present disclosure preferably has the cured product according to the present disclosure and the color filter according to the present disclosure described above. The configuration of the solid-state imaging device according to the present disclosure is not particularly limited as long as it has the film according to the present disclosure and functions as a solid-state imaging device, and examples thereof include the following configurations.
[0241] The substrate has a plurality of photodiodes constituting a light receiving area of a solid-state imaging device (such as a CCD (charge-coupled device) image sensor or a CMOS (complementary metal oxide semiconductor) image sensor) and a transfer electrode made of polysilicon or the like, a light shielding film having an opening only for the light receiving portion of the photodiode on the photodiode and the transfer electrode, a device protection film made of silicon nitride or the like formed on the light shielding film so as to cover the entire light shielding film and the light receiving portion of the photodiode, and a color filter on the device protection film. Furthermore, the device protection film may have a light collecting means (e.g., a microlens, etc., the same applies below) on the device protection film and below the color filter (on the side closer to the substrate), or a light collecting means on the color filter. The color filter may have a structure in which each colored pixel is embedded in a space partitioned by partitions, for example, in a lattice shape. 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 Application Publication No. 2012-227478, Japanese Patent Application Publication No. 2014-179577, International Publication No. 2018 / 043654, and U.S. Patent Application Publication No. 2018 / 0040656. An imaging device including the solid-state imaging element according to the present invention can be used not only in digital cameras and electronic devices having an imaging function (such as mobile phones), but also in vehicle-mounted cameras and surveillance cameras. In addition, as described in JP 2019-211559 A, the solid-state imaging element according to the present disclosure may have an ultraviolet absorbing layer (UV cut filter) in the structure of the solid-state imaging element, thereby improving the light resistance of the color filter.

[0281] <Evaluation method> -Adhesion evaluation- Each colored photosensitive composition was applied by spin coating onto an 8-inch (20.32 cm) silicon wafer so that the film thickness after post-baking would be 0.5 μm. Then, the wafer was pre-baked at 100° C. for 2 minutes using a hot plate. Next, the wafer was exposed to 200 mJ / cm 2 of light using an i-line stepper exposure system FPA-3000i5+ (Canon Inc.) through a mask having a Bayer pattern that forms a predetermined pixel (pattern) size. 2 The mask used had a Bayer pattern with pixel patterns of 0.7 μm square, 0.8 μm square, 0.9 μm square, 1.0 μm square, 1.1 μm square, 1.2 μm square, 1.3 μm square, 1.4 μm square, 1.5 μm square, 1.7 μm square, 2.0 μm square, 3.0 μm square, 5.0 μm square, and 10.0 μm square. Next, paddle development was performed at 23° C. for 60 seconds using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH). After that, rinsing was performed by a spin shower using pure water. Next, a pattern (pixel) was formed by heating (post-baking) at 200° C. for 5 minutes using a hot plate. Using a high-resolution FEB length measuring device (HITACHI CD-SEM) S9380II (manufactured by Hitachi High-Technologies Corporation), patterns of 0.7 μm square, 0.8 μm square, 0.9 μm square, 1.0 μm square, 1.1 μm square, 1.2 μm square, 1.3 μm square, 1.4 μm square, 1.5 μm square, 1.7 μm square, 2.0 μm square, 3.0 μm square, 5.0 μm square, and 10.0 μm square were observed, and the smallest pattern size at which a pattern was formed without peeling was taken as the minimum contact line width. The smaller the minimum contact line width, the better the adhesion. [Evaluation Criteria] A: The minimum contact line width is 1.2 μm square or less. B: The minimum contact line width is greater than 1.2 μm square and less than or equal to 1.3 μm square. C: The minimum contact line width is greater than 1.3 μm square and less than or equal to 1.4 μm square. D: The minimum contact line width is greater than 1.4 μm square and less than or equal to 1.6 μm square. E: The minimum contact line width is greater than 1.6 μm square.
[0282] -Storage stability evaluation- The viscosity of the colored photosensitive composition obtained above was measured using "RE-85L" manufactured by Toki Sangyo Co., Ltd., and the colored photosensitive composition was left to stand at 45°C for 3 days, and the viscosity was measured again. The storage stability was evaluated based on the viscosity difference (ΔVis) before and after standing according to the following evaluation criteria. The smaller the viscosity difference (ΔVis) value, the better the storage stability. The viscosity of the colored photosensitive composition was measured at a temperature adjusted to 25°C. The evaluation criteria were as follows. did. [Evaluation Criteria] A: ΔVis is 0.5 mPa s or less. B: ΔVis is greater than 0.5 mPa·s and less than 2.0 mPa·s. C: ΔVis is greater than 2.0 mPa·s.
[0283] -Developability evaluation- CT-4000 (manufactured by Fujifilm Electronic Materials Co., Ltd.) was applied to a silicon wafer by spin coating to a film thickness of 0.1 μm, and heated at 220° C. for 1 hour using a hot plate to form an undercoat layer. Each curable composition was applied to the silicon wafer with the undercoat layer by spin coating, and then heated at 100° C. for 2 minutes using a hot plate to obtain a composition layer with a film thickness of 1 μm. An i-line stepper FPA-3000i5+ (manufactured by Canon Inc.) was used to apply a 365 nm sieve to this composition layer through a mask pattern in which square pixels with sides of 1.1 μm were arranged in an area of 4 mm×3 mm on the substrate. The exposure was 200 mJ / cm 2 The composition layer after exposure was paddle-developed at 23°C for 60 seconds using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide. Thereafter, the composition layer was rinsed with water using a spin shower, and then washed with pure water. Thereafter, the water droplets were blown off with high-pressure air, and the silicon wafer was naturally dried, and then post-baked at 200°C for 300 seconds using a hot plate to form a pattern. The developability was evaluated by observing the presence or absence of residuals between the patterns. The area outside the pattern formation area (unexposed area) was observed with a scanning electron microscope (SEM) (magnification 10,000 times), and residues with a diameter of 0.1 μm or more per 5 μm × 5 μm area (1 area) of the unexposed area were counted and evaluated according to the following evaluation criteria. A: Absolutely no residue per area. B: The number of residues per area is less than 10. C: The number of residues per area is 10 or more and less than 20. D: The number of residues per area is greater than or equal to 20 and less than 30.
[0284] [Table 6]
[0285] As shown in Table 6 above, the colored photosensitive compositions of Examples 1 to 82 were superior in adhesion to the resulting cured products as compared with the colored photosensitive compositions of Comparative Examples 1 and 2. Furthermore, as shown in Table 6 above, the colored photosensitive compositions in Examples 1 to 82 were also excellent in storage stability and developability.
[0286] (Examples 101 to 154, and Examples 156 to 182) The Green composition was applied onto a silicon wafer by spin coating so that the film thickness after formation would be 1.0 μm. Then, the wafer was heated at 100° C. for 2 minutes using a hot plate. Then, an i-line stepper exposure system FPA-3000i5+ (Canon Inc.) was used to expose the wafer at 1,000 mJ / cm 2 The film was exposed to light through a mask with a 2 μm square dot pattern. Then, paddle development was performed at 23°C for 60 seconds using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH). After that, rinsing was performed with a spin shower and further washed with pure water. Next, the green composition was patterned on the silicon wafer by heating at 200°C for 5 minutes using a hot plate. Similarly, the red composition and the blue composition were patterned in sequence to form red, green and blue colored patterns (Bayer patterns). In Examples 101 to 154 and Examples 156 to 182, the colored photosensitive compositions prepared in Examples 1 to 54 and Examples 56 to 82 were used as the Red compositions. Other than the above colored photosensitive composition, the Green composition and the Blue composition will be described later. The Bayer pattern is a repeated 2 x 2 array of color filter elements, each having one red element, two green elements, and one blue element, as disclosed in U.S. Pat. No. 3,971,065. The obtained color filter was incorporated into a solid-state imaging device according to a known method. It was confirmed that the solid-state imaging device had excellent adhesion in the cured film and favorable image recognition ability, regardless of whether any of the colored photosensitive compositions obtained in Examples 1 to 76 was used.
