Abstract
Description
Technical Field
[0001] The present invention relates to a coloring composition containing a pigment. Furthermore, the present invention relates to a film, a red pixel, a color filter, a solid-state imaging element, and an image display device formed using the coloring composition. Furthermore, the present invention relates to a kit. Background Art
[0002] In recent years, with the widespread use of digital cameras and mobile phones with cameras, demand for solid-state imaging devices such as charge-coupled devices (CCD) image sensors has increased significantly. Color filters are used as core components in displays and optical devices. Color filters typically have pixels for the three primary colors of red, green, and blue, and they function to decompose transmitted light into these three primary colors.
[0003] The colored pixels of each color of the color filter are manufactured using a coloring composition containing a colorant such as a pigment. Furthermore, the coloring composition used to form red pixels uses a diketopyrrolopyrrole pigment or the like as a red pigment. For example, Patent Document 1 describes a technique for forming red pixels using a coloring composition containing a red pigment such as Color Index Pigment Red 272 as a diketopyrrolopyrrole pigment.

[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2015-168725 Summary of the Invention
[0007] Technical issues to be solved by the invention
[0008] The present inventors conducted extensive research on coloring compositions containing Color Index Pigment Red 272, and found that Color Index Pigment Red 272 tends to have higher crystallinity than other diketopyrrolopyrrole pigments, and aggregates due to crystallization and other factors in the film, which tends to precipitate as impurities. In particular, when a film formed using a coloring composition containing Color Index Pigment Red 272 is left for a long time in a high-humidity environment, aggregation occurs due to crystallization and other factors in the film, and the film tends to precipitate as an impurity.

[0052] <Coloring Composition>
[0053] The coloring composition of the present invention comprises a pigment containing color index Pigment Red 272, a curable compound, and a solvent. In the coloring composition,
[0054] The content of the pigment in the total solid content of the colored composition is 30% by mass or more.
[0055] The coloring composition of the present invention can form a film in which the generation of impurities is suppressed even when the obtained film is left for a long time under a high humidity environment, despite containing CI (Color Index) Pigment Red 272. The reason for this effect is presumably as follows.
[0056] CI Pigment Red 272 is a diketopyrrolopyrrole pigment with a relatively low molecular weight. Therefore, it is speculated that it tends to be more crystalline than other diketopyrrolopyrrole pigments, forming aggregates in the film due to crystallization, which tends to precipitate as impurities. Furthermore, it is speculated that when the film is exposed in a high-humidity environment, the film softens, causing the diketopyrrolopyrrole pigment in the film to migrate, which tends to easily form aggregates. It is speculated that the relatively low molecular weight of CI Pigment Red 272 makes it easy to migrate in the softened film, resulting in the easy precipitation of impurities in the film.
[0057] In the colored composition of the present invention, by setting the pigment content in the total solid content of the colored composition to 30% by mass or more, the interaction between the pigments in the film becomes stronger, the apparent molecular weight becomes larger, and the migration of the pigment in the softened film can be suppressed. As a result, it is estimated that even when the obtained film is left for a long time in a high humidity environment, the generation of impurities can be suppressed.
[0058] The CI Pigment Red 272 used in the coloring composition of the present invention has a higher red color value than conventional red pigments, and thus can form a cured film having desired spectral characteristics even in thin films. Furthermore, because CI Pigment Red 272 has a higher red color value than conventional red pigments, it can achieve a desired spectrum with a smaller blending amount than that required to achieve spectral characteristics equivalent to those of conventional red pigments. This allows for an increase in the blending amount of components other than the pigment, resulting in a high degree of freedom in formulation design.
[0059] The coloring composition of the present invention can be suitably used as a coloring composition for solid-state imaging elements. Furthermore, the coloring composition of the present invention can be suitably used as a coloring composition for color filters. Specifically, it can be suitably used as a coloring composition for forming pixels of a color filter, and can be more suitably used as a coloring composition for forming red pixels of a color filter. Furthermore, the coloring composition of the present invention can be suitably used as a coloring composition for forming pixels of a color filter used in a solid-state imaging element. Furthermore, the coloring composition of the present invention can also be used as any one of a coloring composition for photolithography and a coloring composition for dry etching, but can be suitably used as a coloring composition for photolithography because the process for forming pixels is simple and the process load is small. When used as a coloring composition for photolithography, the coloring composition of the present invention preferably uses a coloring composition comprising a resin and a polymerizable compound (preferably a polymerizable monomer) as a curable compound. Furthermore, it is preferred that a photopolymerization initiator is also included. Furthermore, the coloring composition of the present invention can also be used as a coloring composition for forming an infrared transmission filter.
[0060] Hereinafter, each component used for the coloring composition of the present invention will be described.

[0062] The coloring composition of the present invention contains a colorant. A colorant containing a pigment can be used as the colorant. The content of the pigment in the colorant is preferably 30% by mass or greater, more preferably 50% by mass or greater, further preferably 60% by mass or greater, and particularly preferably 80% by mass or greater. Furthermore, the colorant may consist solely of the pigment.
[0063] In the coloring composition of the present invention, as the pigment, a pigment including CI Pigment Red 272 can be used. CI Pigment Red 272 is a red pigment.
[0064] The content of CI Pigment Red 272 in the total amount of pigments contained in the coloring composition is preferably 10% by mass or more, more preferably 15% by mass or more, and even more preferably 20% by mass or more. The upper limit can be 100% by mass or less, 95% by mass or less, 85% by mass or less, 75% by mass or less, or 50% by mass or less.
[0065] The content of CI Pigment Red 272 in the total amount of red pigment is preferably 25 to 100% by mass, more preferably 30 to 100% by mass, and even more preferably 40 to 100% by mass. The upper limit of the content of CI Pigment Red 272 can also be set to 90% by mass or less, and can also be set to 80% by mass or less.

[0067] Furthermore, the red pigment contained in the pigment used in the coloring composition of the present invention may consist essentially only of CI Pigment Red 272. This embodiment enables the production of red pixels with higher color separation performance.

Such organic solvents are provided, for example, by Toyo Gosei Co., Ltd. (Chemical Industry Daily, November 13, 2015).
[0237] Examples of methods for removing impurities such as metals from organic solvents include distillation (molecular distillation or thin film distillation) or filtration using a filter. 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 filter is preferably made of polytetrafluoroethylene, polyethylene, or nylon.
[0238] The organic solvent may contain isomers (compounds having the same number of atoms but different structures). The isomers may be one or more.
[0239] The content of peroxide in the organic solvent is preferably 0.8 mmol / L or less, and more preferably substantially no peroxide is contained.
[0240] The content of the solvent 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.
[0241] Furthermore, from the perspective of environmental regulation, the coloring composition of the present invention preferably does not substantially contain environmentally regulated substances. In addition, in the present invention, substantially containing no environmentally regulated substances means that the content of environmentally regulated substances in the coloring composition is 50 mass ppm or less, preferably 30 mass ppm or less, more preferably 10 mass ppm or less, and particularly preferably 1 mass ppm or less. Examples of environmentally regulated substances include benzene; alkylbenzenes such as toluene and xylene; halogenated benzenes such as chlorobenzene, etc. These are registered as environmentally regulated substances under REACH (Registration Evaluation Authorization and Restriction of Chemicals) regulation, PRTR (Pollutant Release and Transfer Register) law, VOC (Volatile Organic Compounds) regulation, etc., and their usage and disposal methods are strictly regulated. These compounds are sometimes used as solvents when manufacturing the various components used in the coloring composition, and sometimes they are mixed into the coloring composition as residual solvents. From the perspective of human safety and environmental considerations, it is preferable to reduce these substances as much as possible. As a method for reducing environmental control substances, it is possible to enumerate heating and decompression of the system interior and setting it to more than the boiling point of the environmental control substances, and distilling the environmental control substances from the system interior and reducing the method thereof. In addition, in the case of distilling a small amount of environmental control substances, it is also useful to azeotrope the solvent with the boiling point identical to the solvent in order to improve efficiency. In addition, when containing a compound with free radical polymerizability, it is possible to remove it by decompression distillation after adding a polymerization inhibitor, so as to suppress the free radical polymerization reaction in the decompression distillation removal and cause crosslinking between molecules. These distillation removal methods can be carried out in any stage of the raw material stage, the stage of the product (such as the resin solution or the multifunctional monomer solution after polymerization) of the raw material reaction, or the stage of the coloring composition made by mixing these compounds.

[0370] <Pixel Formation Method>
[0371] Next, the pixel formation method is described. The pixel formation method can be produced by applying the above-mentioned coloring composition of the present invention on a support to form a coloring composition layer, and patterning the coloring composition layer by photolithography or dry etching.
[0372] (Photolithography)
[0373] First, the case of forming pixels by patterning using photolithography will be described. Patterning using photolithography preferably includes a step of applying the aforementioned colored composition of the present invention onto a support to form a colored composition layer, a step of exposing the colored composition layer in a pattern, and a step of developing and removing the unexposed portions of the colored composition layer after exposure. Each step is described below.
[0374] In the process of forming the colored composition layer, the colored composition is applied to a support to form a colored composition layer. There is no particular limitation on the support, and it can be appropriately selected according to the intended use. For example, a glass substrate, a silicon substrate, etc. can be mentioned, preferably a silicon substrate. In addition, a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), a transparent conductive film, etc. can be formed on the silicon substrate. In addition, a black matrix is sometimes formed on the silicon substrate to isolate each pixel. In addition, in order to improve the adhesion with the upper layer, prevent the diffusion of substances or flatten the surface of the substrate, a base layer can be provided on the silicon substrate. The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane. And, 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 wettability of the colored composition is good. The surface contact angle of the base layer can be adjusted, for example, by adding a surfactant or the like.
[0375] As a method for applying the coloring composition, known methods can be used. Examples include a drop casting method, a slit coating method, a spray method, a roll coating method, a spin coating method, a cast coating method, a slit spin coating method, a pre-wetting method (for example, the method described in Japanese Patent Application Laid-Open No. 2009-145395), various printing methods such as inkjet (for example, on-demand, piezoelectric, and thermal), nozzle jet printing, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing, transfer methods using a mold, etc., and nanoimprinting methods. The inkjet application method is not particularly limited. For example, the method described in "Inkjet for General Use - Infinite Possibilities Emerging from Patents" published in February 2005 by Sumitbe Techon Research Co., Ltd. (particularly pages 115 to 133) or methods described in Japanese Patent Application Publication Nos. 2003-262716, 2003-185831, 2003-261827, 2012-126830, and 2006-169325 can be cited. Regarding the method for applying the coloring composition, reference can be made to the descriptions of International Publication Nos. 2017 / 030174 and 2017 / 018419, the contents of which are incorporated herein.
[0376] The colored composition layer formed on the support can be dried (prebaked). When the film is manufactured by a low-temperature process, prebaking is not required. When prebaking is performed, the prebaking temperature is preferably 150°C or less, more preferably 120°C or less, and further preferably 110°C or less. The lower limit can be set to, for example, 50°C or more, or 80°C or more. The prebaking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and further preferably 80 to 220 seconds. Prebaking can be performed using a hot plate, an oven, or the like.
[0377] Next, the colored composition layer is exposed in a pattern (exposure step). For example, a stepper or scanner is used to expose the colored composition layer through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.
[0378] Examples of radiation (light) that can be used for exposure include g-rays and i-rays. Furthermore, 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. Furthermore, light sources with a long wavelength of 300 nm or more can also be used.
[0379] Furthermore, during exposure, light can be irradiated continuously or in pulses (pulse exposure). Pulse exposure refers to an exposure method in which light is irradiated and paused repeatedly in a short cycle (e.g., milliseconds or less) to perform exposure.
[0380] The irradiation dose (exposure dose) is preferably, for example, 0.03 to 2.5 J / cm 2 , more preferably 0.05 to 1.0 J / cm 2 The oxygen concentration during exposure can be appropriately selected. In addition to being performed under the atmosphere, exposure can be performed under a low oxygen environment with an oxygen concentration of 19% by volume or less (e.g., 15% by volume, 5% by volume, or substantially oxygen-free), or under a high oxygen environment with an oxygen concentration exceeding 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). Furthermore, the exposure illuminance can be appropriately set, typically from 1000 W / m 2 ~100000W / m 2 (For example, 5000W / m 2 、15000W / m 2 or 35000W / m 2 The oxygen concentration and exposure illuminance can be appropriately combined, for example, the oxygen concentration can be set to 10% by volume and the illuminance can be set to 10000 W / m2 , oxygen concentration 35% by volume and illumination 20,000 W / m 2 wait.
[0381] Next, the unexposed portions of the colored composition layer after exposure are removed by development (development step). The unexposed portions of the colored composition layer can be removed by development using a developer. This dissolves the unexposed portions of the colored composition layer in the developer, leaving only the photocured portions. The developer temperature is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. Furthermore, to improve residue removability, the process of discarding the developer and supplying fresh developer every 60 seconds can be repeated multiple times.
[0382] Developer can enumerate organic solvent, alkaline developer etc., can suitably use alkaline developer.As alkaline developer, it is preferably alkaline aqueous solution (alkaline developer) obtained by diluting alkaline agent with pure water.As alkaline agent, for example, ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine (diglycolamine), diethanolamine, hydroxylamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis (2-hydroxyethyl) ammonium hydroxide, choline, pyrrole, piperidine, 1,8-diazabicyclo-[5.4.0]-7-undecene and other organic alkaline compounds or sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, sodium metasilicate and other inorganic alkaline compounds can be enumerated.In terms of environment and safety, alkaline agent is preferably a compound with large molecular weight. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. In addition, the developer may further contain a surfactant. From the perspective of convenient transportation or storage, the developer can be temporarily manufactured as a concentrated solution and diluted to the desired concentration when used. The dilution ratio is not particularly limited, for example, it can be set in the range of 1.5 to 100 times. In addition, it is also preferred to wash (rinse) with pure water after development. In addition, it is preferred to rotate the support on which the developed colored composition layer has been formed and supply a rinsing liquid to the developed colored composition layer for rinsing. In addition, it is also preferred to move the nozzle that discharges the rinsing liquid from the center of the support to the peripheral portion of the support. At this time, when the nozzle moves from the center of the support to the peripheral portion, it can be moved while gradually reducing the movement speed of the nozzle. By rinsing in this way, the in-plane deviation of the rinsing can be suppressed. In addition, the same effect can be obtained by gradually reducing the rotation speed of the support while moving the nozzle from the center of the support to the peripheral portion.
[0383] After development, it is preferred to perform additional exposure treatment and heating treatment (post-baking) after drying. Additional exposure treatment and post-baking are curing treatments after development for making a completely cured substance. The heating temperature in the post-baking is preferably 100 to 240°C, more preferably 200 to 240°C. The developed film (pixel) can be post-baked continuously or intermittently using a heating mechanism such as a hot plate, a convection oven (hot air circulation dryer), or a high-frequency heater in such a manner as to achieve the above conditions. In the case of performing additional exposure treatment, it is preferred that the light used for exposure is light with a wavelength of 400nm or less. In addition, the additional exposure treatment can be performed by the method described in Korean Patent Publication No. 10-2017-0122130.
[0384] (Dry Etching Method)
[0385] The pattern formation based on the dry etching method preferably includes the following steps: forming a colored composition layer on a support using the above-mentioned colored composition of the present invention, and curing the entire colored composition layer to form a cured product layer; forming a photoresist layer on the cured product layer; exposing the photoresist layer to a pattern, and then developing it to form a resist pattern; and using the resist pattern as a mask and dry etching the cured product layer using an etching gas. When forming the photoresist layer, it is preferred to further perform a pre-baking treatment. In particular, as a step for forming the photoresist layer, it is preferred to perform a post-exposure heat treatment and a post-development heat treatment (post-baking treatment). Regarding the pattern formation using the dry etching method, reference can be made to the description of paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, and the content is incorporated into this specification.
