Description

Coloring composition, film, color filter, solid-state imaging device and image display device

[0001] The present invention relates to a coloring composition containing a dye. The present invention also relates to a film, a color filter, a solid-state imaging device, and an image display device using the coloring composition.

[0002] In recent years, the widespread use of digital cameras and smartphones has led to a significant increase in demand for solid-state imaging devices such as complementary metal-oxide semiconductor (CMOS) image sensors. Color filters are used as key devices in displays and optical elements. Color filters typically have pixels for the three primary colors of red, green, and blue, and serve to separate transmitted light into the three primary colors.

[0003] The pixels of each color of the color filter are manufactured by, for example, forming a pattern by photolithography using a coloring composition containing a colorant. For example, Patent Document 1 describes forming a pattern by photolithography using a coloring composition containing an acid dye, a binder resin, a predetermined ionic compound whose maximum molar absorption coefficient ε in the visible light region is 0 to 3000, and an organic solvent, to form the pixels of the color filter.

[0005] Generally, dyes tend to have lower lightfastness than pigments, and there is room for further improvement in the lightfastness of films obtained using colored compositions containing dyes.

[0011] <Coloring composition> The coloring composition of the present invention comprises: a colorant A containing a dye a; a polymerization initiator B; a polymerizable compound C; and a compound D which is a salt of a cation dx and an anion dz and is represented by formula (Aλ) and has a specific absorbance of 5 or less, wherein the anion dz is an anion containing a boron atom and has a fluorine atom content of 50 mass% or less.

[0012] The coloring composition of the present invention can form a film with excellent light resistance. While the detailed reasons for this effect are unclear, it is presumed to be due to the following. Here, the mechanism by which the dye decomposes when a dye-containing film is irradiated with light is presumed to be as follows. Specifically, it is presumed that irradiating a dye-containing film with light excites the dye, transferring energy to nearby oxygen to generate singlet oxygen, which then oxidizes and decomposes the dye. It is presumed that this mechanism causes the dye in the film to be decomposed by light irradiation. The anion dz in the above-described compound D is an anion containing a boron atom, and the fluorine atom content is 50% by mass or less, which facilitates proximity to the dye through π-π interactions with the dye. Furthermore, it is presumed that the anion dz in proximity to the dye can effectively prevent oxygen from approaching the dye. Therefore, even if the dye is excited by light irradiation, the anion dz can prevent oxygen from approaching the dye, thereby suppressing the generation of singlet oxygen. As a result, it is presumed that decomposition of the dye due to light irradiation can be suppressed. For this reason, it is presumed that the colored composition of the present invention can form a film that is excellent in light resistance and in which spectral variation due to light irradiation is suppressed.

[0013] Furthermore, the colored composition of the present invention has good storage stability and can also form a film with excellent adhesiveness.

[0014] Furthermore, the colored composition of the present invention can effectively suppress the generation of development residues when a pattern is formed by photolithography. This is presumably because the anion dz in the above-mentioned compound D has a fluorine atom content of 50 mass% or less, thereby increasing the affinity with the developer.

More specifically, it can be preferably used as a coloring composition for forming pixels of color filters. Examples of types of pixels in color filters include red pixels, green pixels, blue pixels, magenta pixels, cyan pixels, and yellow pixels.

The thickness of the protective layer is preferably 0.01 to 10 μm, more preferably 0.1 to 5 μm. Methods for forming the protective layer include a method of applying a resin composition dissolved in an organic solvent, a chemical vapor deposition method, and a method of attaching a molded resin with an adhesive. 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, fluororesin, polyacrylonitrile resin, cellulose resin, Si, C, W, Al ２ O ３ , Mo, SiO ２ , Si ２ N ４ For example, in the case of a protective layer intended to block oxygen, the protective layer may contain a polyol resin and SiO ２ and Si ２ N ４ In the case of a protective layer intended to reduce reflection, the protective layer preferably contains a (meth)acrylic resin and a fluorine resin.

[0256] When forming a protective layer by applying a resin composition, known methods such as spin coating, casting, screen printing, and inkjet printing 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 forming the protective layer 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 method.

[0257] The protective layer may contain additives such as organic or inorganic fine particles, absorbers for light of specific wavelengths (e.g., ultraviolet light, near-infrared light, etc.), refractive index adjusters, antioxidants, adhesives, and surfactants, as needed. Examples of organic or inorganic fine particles include polymeric fine particles (e.g., silicone resin fine particles, polystyrene fine particles, melamine resin fine 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 absorbers for light of specific wavelengths can be used. 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, of the total mass of the protective layer.

[0258] In addition, as the protective layer, the protective layers described in paragraphs 0073 to 0092 of JP-A-2017-151176 can also be used.

[0259] The color filter may have a structure in which each pixel is embedded in a space partitioned by partition walls, for example, in a grid pattern.

[0260] <Method for producing a color filter> Next, a method for producing a color filter using the colored composition of the present invention will be described. The method for producing a color filter preferably includes a step of forming a colored composition layer on a support using the colored composition of the present invention, a step of patternwise exposing the colored composition layer, and a step of developing and removing the unexposed areas of the colored composition layer to form a pattern (pixels). If necessary, a step of baking the colored composition layer (pre-baking step) and a step of baking the developed pattern (pixels) (post-baking step) may be provided.

[0261] In the step of forming a coloring composition layer, a coloring composition layer is formed on a support using the coloring composition of the present invention. The support is not particularly limited and can be appropriately selected depending on the application. Examples include a glass substrate and a silicon substrate, with a silicon substrate being preferred. The silicon substrate may also be formed with a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), a transparent conductive film, or the like. A black matrix is ​​sometimes formed on the silicon substrate to isolate each pixel. The silicon substrate may also be provided with a base layer to improve adhesion with an upper layer, prevent diffusion of substances, or flatten the substrate surface. 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.

[0262] As the coating method of the coloring composition, known methods can be used. 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); inkjet (for example, an on-demand method, a piezo method, a thermal method), various printing methods such as nozzle jet and other ejection printing, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing; a transfer method using a mold or the like; a nanoimprint method, etc. can be mentioned. In addition, the coating method described in paragraph 0207 of WO 2022 / 085485 can also be used.

[0263] The colored composition layer formed on the support may be dried (prebaked). When a film is produced by a low-temperature process, prebaking may not be performed. When prebaking is performed, the prebaking temperature is preferably 150°C or lower, more preferably 120°C or lower, and even more preferably 110°C or lower. The lower limit can be, for example, 50°C or higher, or can also be 80°C or higher. The prebaking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and even more preferably 80 to 220 seconds. Prebaking can be performed using a hot plate, an oven, or the like.

[0264] Next, the coloring composition layer is exposed to light in a pattern (exposure step). For example, the coloring composition layer can be exposed to light in a pattern by using a stepper exposure machine, a scanner exposure machine, or the like, through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.

[0265] Examples of radiation (light) that can be used for exposure include g-rays and i-rays. Light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) can also be used. Examples of light with a wavelength of 300 nm or less include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm), with KrF rays (wavelength 248 nm) being preferred. Long-wave light sources of 300 nm or more can also be used. As the light source, an electrodeless ultraviolet lamp system or a hybrid curing method using ultraviolet and infrared rays can be used.

[0266] The exposure may be performed by continuous irradiation with light or by pulsed irradiation (pulse exposure), which is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, milliseconds or less).

[0267] The irradiation amount (exposure amount) is, for example, 0.03 to 2.5 J / cm ２ is preferred, and 0.05 to 1.0 J / cm ２The oxygen concentration during exposure can be appropriately selected. In addition to being performed in the atmosphere, exposure may be performed in a low-oxygen atmosphere with an oxygen concentration of 19% by volume or less (e.g., 15% by volume, 5% by volume, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration of more than 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). The exposure illuminance can be appropriately set, and is usually 1000 W / m ２ ~100000W / m ２ (For example, 5000 W / m ２ , 15000W / m ２ , or 35,000 W / m ２ The oxygen concentration and exposure illuminance may be appropriately combined. For example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m ２ , oxygen concentration 35% by volume, illuminance 20,000 W / m ２ etc.

[0268] Next, the unexposed portions of the coloring composition layer are developed and removed to form a pattern (pixels). The unexposed portions of the coloring composition layer can be developed and removed using a developer. As a result, the unexposed portions of the coloring composition layer in the exposure step are dissolved into the developer, leaving only the photocured portions. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, to improve residue removability, the process of shaking off the developer every 60 seconds and then supplying fresh developer may be repeated several times.

[0269] Examples of the developer include organic solvents and alkaline developers, and alkaline developers are preferably used. Regarding the developer and the washing (rinsing) method after development, the developer and washing method described in paragraph 0214 of WO 2022 / 085485 can be used.

[0270] After development and drying, it is preferable to perform additional exposure treatment or heating treatment (post-baking). The additional exposure treatment or post-baking is a post-development curing treatment to ensure complete curing. The heating temperature in post-baking is, for example, preferably 100 to 300°C, more preferably 200 to 270°C. Post-baking can be performed continuously or batchwise using a heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to achieve the above conditions for the developed film. When additional exposure treatment is performed, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure treatment may also be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

[0272] The substrate includes 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 transfer electrodes made of polysilicon or the like. A light-shielding film is formed on the photodiodes and transfer electrodes, with only the light-receiving portions of the photodiodes exposed. A device protection film made of silicon nitride or the like is formed on the light-shielding film so as to cover the entire light-shielding film and the light-receiving portions of the photodiodes. A color filter is also provided on the device protection film. Furthermore, the device protection film may include a light-collecting means (e.g., a microlens, etc.; the same applies hereinafter) below the color filter (on the side closer to the substrate), or on the color filter. The color filter may have a structure in which each color pixel is embedded in a space partitioned by partition walls, for example, in a grid pattern. In this case, the partition walls preferably have a lower refractive index than the color pixels. Examples of imaging devices having such a structure include those described in JP 2012-227478 A, JP 2014-179577 A, and WO 2018 / 043654 A. Furthermore, as shown in JP 2019-211559 A, an ultraviolet absorbing layer may be provided within the structure of the solid-state imaging element to improve light resistance. An imaging device equipped with the solid-state imaging element of the present invention can be used for digital cameras, electronic devices with imaging functions (such as mobile phones), as well as in-vehicle cameras and surveillance cameras.

The mixture was stirred at 200 rpm using a Three-One motor to dissolve the contents. A separately prepared aqueous solution of 8.12 g of tetrabutylammonium chloride and 100 g of ion-exchanged water was added dropwise to the flask using a dropping funnel over 30 minutes. After stirring for 1 hour after the addition, the mixture was filtered using a Kiriyama funnel. The residue was washed with ion-exchanged water and air-dried for 30 minutes. The residue was transferred to a petri dish and dried for 12 hours to a constant weight using a blower dryer set at 40°C, yielding Compound D-1. Analysis using an X-ray fluorescence analyzer (XRF) revealed that the residual Na ions were 1000 ppm and the residual Cl ions were 1000 ppm.

[0276] (Synthesis Example of Compound D-5) 10 g of sodium tetraphenylborate (Kalibor, manufactured by Dojindo Laboratories, Inc.) and 100 g of methanol were placed in a three-necked flask, and a stirring blade and a thermometer were installed. The mixture was stirred at 200 rpm using a Three-One motor to dissolve the compound. A separately prepared aqueous solution of 3.15 g of potassium acetate and 100 g of methanol was added dropwise to the flask using a dropping funnel over 30 minutes. After the dropwise addition, the mixture was stirred for 1 hour and then filtered using a Kiriyama funnel. The residue was washed with ion-exchanged water and air-dried for 30 minutes. The residue was transferred to a petri dish and dried for 12 hours to a constant weight using a blower dryer set at 40°C to obtain Compound D-5. 1 g of the obtained Compound D-5 was dissolved in 30 g of acetone, and 50 g of ion-exchanged water was added to precipitate Compound D-5. The solvent was then removed using a rotary evaporator at 45 torr and 30°C for 30 minutes. The filtrate was collected using a Kiriyama funnel and a filter bell, and ion-exchanged water was added to bring the total amount to 100 g. The resulting liquid was analyzed by ion chromatography, and the analytical results were converted into the residual amounts in Compound D-5. The residual amount of Na was 100 ppm, and the amount of acetate anion was below the lower detection limit (10 ppm).

[0277] (Synthesis Example of Compound D-8) 2.4 g of magnesium and 10 ml of ultra-dehydrated tetrahydrofuran (THF) were added to a three-neck flask. A stirring blade, a nitrogen inlet tube, a condenser, and a thermometer were installed via a Y-shaped tube, and nitrogen was flowed at 20 ml / min. A calcium chloride tube filled with calcium chloride as a desiccant was installed in the condenser. The mixture was heated in a water bath to an internal temperature of 30°C, and stirred at 200 rpm using a three-one motor. 0.2 g of 1,2-dibromoethane was added to the reaction solution, and the generation of fine bubbles was confirmed. Separately, 14.1 g of 4-bromotoluene was dissolved in 140 g of THF and 40 g of diethyl ether, and the solution was added dropwise to the reaction solution using a dropping funnel at a rate such that the internal temperature remained below 35°C. After the dropwise addition, the mixture was stirred at 30°C for 1 hour to prepare a Grignard reagent. Subsequently, 1.7 g of sodium tetrafluoroborate was added, and the mixture was stirred for 24 hours. The completion of the reaction was confirmed using nuclear magnetic resonance analysis (NMR). 33 g of sodium carbonate and 330 g of ion-exchanged water were added to a 1 L glass beaker and stirred with a stirrer until dissolved, after which the reaction solution was slowly poured into it. After stirring for 20 minutes, the remaining magnesium was removed by filtration through Celite. An extraction operation was performed using diethyl ether, and the resulting organic layer was washed with saturated saline. 5 g of sodium sulfate was added to the organic layer and allowed to stand overnight. The sodium sulfate was removed by filtration, and the solvent was distilled off using an evaporator. When crystals precipitated, toluene was added, and white crystals were obtained by filtration. The residue was transferred to a petri dish and dried for 12 hours to a constant weight using a blower dryer set at 40°C to obtain sodium tetra(p-tolyl)borate. Salt exchange was performed in the same manner as for Compound D-1, except that a reslurry step using ion-exchanged water was introduced, to obtain Compound D-8. Analysis was performed in the same manner as for Compound D-5, and the residual Na content was 200 ppm and the residual Cl content was 30 ppm. Furthermore, analysis using high performance liquid chromatography (HPLC) revealed that the area % purity at 210 nm was 99.1%.

Nitrogen was flowed at 20 ml / min. A calcium chloride tube filled with calcium chloride as a desiccant was installed in the condenser. After stirring at 200 rpm for 30 minutes using a Three-One motor, 35 g of a 5% by mass aqueous potassium hydroxide solution was added, and the mixture was heated in a water bath so that the internal temperature reached 80°C. After stirring for 5 hours, the crystals were filtered out using a Kiriyama funnel. The crystals were washed with a mixture of ion-exchanged water and methanol, air-dried for 30 minutes, transferred to a petri dish, and dried in a 50°C air dryer for 30 hours until a constant weight was obtained, thereby obtaining Compound D-20.

The resulting coating film was exposed to light (KrF line) with a wavelength of 248 nm at an illuminance of 35,000 W / m using a KrF scanner exposure machine. ２ , exposure dose 100 mJ / cm ２The exposure was performed by irradiating under the conditions of . The glass substrate on which the exposed coating film was formed was placed on the horizontal rotating table of a spin-shower developer (DW-30 model, Chemitronics Corporation) and then treated for 60 seconds at 23°C using a 60% diluted solution of CD-2000 (Fujifilm Electronic Materials Co., Ltd.). The glass substrate on which the film was formed after the above treatment was fixed to the horizontal rotating table using a vacuum chuck. While rotating the glass substrate at 50 rpm using a rotation device, pure water was supplied in a shower from a spray nozzle from above the center of rotation to perform a rinse treatment, and then spray-dried. Next, a heat treatment (post-bake) was performed for 300 seconds using a hot plate at 200°C to form a film with a thickness of 0.45 μm. The light transmittance (transmittance) of the obtained film was measured using a spectrometer (MCPD-3000, manufactured by Otsuka Electronics Co., Ltd.) in the wavelength range of 400 to 700 nm. Next, the film was irradiated with 100,000 Lux light for 2,000 hours (total irradiation dose: 200 million Lux hr) using a light resistance tester (Super Xenon Weather Meter SX75, manufactured by Suga Test Instruments Co., Ltd.). The transmittance of the film after light irradiation was measured, and the light resistance was evaluated according to the following criteria. -Evaluation criteria- A: The integrated value of the transmittance of the film at wavelengths of 400 to 700 nm after light irradiation is 98% or more of the integrated value of the transmittance of the film at wavelengths of 400 to 700 nm before light irradiation.

[0310] (Evaluation of Adhesion) An underlayer-forming composition (CT-4000L, Fujifilm Electronic Materials Co., Ltd.) was applied to an 8-inch (20.32 cm) silicon wafer by spin coating, and heated at 220°C for 300 seconds using a hot plate to form an underlayer having a thickness of 0.1 μm, thereby obtaining a silicon wafer (support) with an underlayer. A coloring composition was applied onto the underlayer of the silicon wafer with an underlayer using a spin coater, and then heated (pre-baked) at 100°C for 120 seconds using a hot plate to obtain a coating film having a thickness of 0.45 μm. Next, the coating film was exposed to light (KrF line) with a wavelength of 248 nm through a patterned mask (0.5 μm x 0.5 μm) using a KrF scanner exposure machine at an illuminance of 35,000 W / m ２ , exposure dose 100 mJ / cm ２ The coating film was then exposed to light under the following conditions. The exposed coating film was then shower-developed at 23°C for 60 seconds using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH) as the developer. The coating film was then rinsed with pure water by spin shower and heated at 230°C for 2 minutes to form pixels (patterns).

The resulting coating film was exposed to light (KrF line) with a wavelength of 248 nm through a patterned mask (0.5 µm x 0.5 µm) using a KrF scanner exposure machine at an illuminance of 35,000 W / m ２ , exposure dose 100 mJ / cm ２The glass substrate on which the exposed coating film was formed was placed on the horizontal rotating table of a spin-shower developer (DW-30 model, Chemitronics Corporation), and then puddle development was performed for 60 seconds at 23°C using a 60% diluted solution of CD-2000 (Fujifilm Electronic Materials Co., Ltd.), forming a colored pattern on the glass substrate. The glass substrate on which the colored pattern was formed was fixed to the horizontal rotating table using a vacuum chuck system, and then, while rotating the glass substrate at a rotation speed of 50 rpm using a rotation device, pure water was supplied in a shower-like manner from a spray nozzle from above the center of rotation to perform a rinse treatment, followed by spray drying. Next, a heat treatment (post-bake) was performed for 300 seconds using a hot plate at 200°C, forming a colored pattern (pixels) with a thickness of 0.45 μm.

B: There was little residue between pixels, and there was no practical problem. C: There was a little amount of residue between pixels, but there was no practical problem. D: There was a lot of residue between pixels. E: It was not possible to form pixels.

[0312] (Evaluation of storage stability) The initial viscosity (V0) of the colored composition was measured using "RE-85L" manufactured by Toki Sangyo Co., Ltd. Next, the colored composition was left to stand at 45°C for 7 days, and then the viscosity (V1) was measured. The viscosity increase rate (%) of the colored composition after standing was calculated based on the following formula, and the storage stability was evaluated. The smaller the viscosity increase rate (%), the better the storage stability. The viscosity of the colored composition was measured in a state where the temperature was adjusted to 25°C. Viscosity increase rate (%) = [(viscosity after standing (V1) - initial viscosity (V0)) / initial viscosity (V0)] × 100 - Evaluation criteria - A: Viscosity increase rate is less than 1% B: Viscosity increase rate is 1% or more but less than 3% C: Viscosity increase rate is 3% or more but less than 5% D: Viscosity increase rate is 5% or more but less than 10%

Next, an i-line stepper exposure system FPA-3000i5+ (manufactured by Canon Inc.) was used to apply a 1000 mJ / cm ２ The wafer was exposed to light through a mask with a 2 μm square dot pattern at an exposure dose of 1000 μm. Next, puddle development was performed using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH) at 23°C for 60 seconds. The wafer was then rinsed with a spin shower and further washed with pure water. The green pixel-forming composition was then patterned on the silicon wafer by heating at 200°C for 5 minutes using a hot plate. Similarly, the red pixel-forming composition and the blue pixel-forming composition were sequentially patterned to form red, green, and blue colored patterns (Bayer patterns). In Examples 501 to 510, the compositions listed in the table below were used for the blue pixel-forming composition, green pixel-forming composition, and red pixel-forming composition. The Bayer pattern is a repeated 2 × 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. By using the colored compositions prepared in Examples 1 to 10, solid-state imaging devices having suitable image recognition functions and light resistance were obtained.
