[0001] The present invention relates to a colored composition. More specifically, the present invention relates to a colored composition used for forming blue pixels in a color filter. The present invention also relates to a cured film, a color filter, and a display device using the colored composition. [Background technology]

[0002] In various display devices, color filters are generally used to colorize displayed images.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-094593 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, further improvements in light resistance have been required for cured films used in color filters and the like.

[0005] In recent years, color filters are sometimes formed on components with low heat resistance (for example, organic semiconductor elements such as organic electroluminescence display elements). Because such components have low heat resistance, it is desirable to form a cured film used for color filters, etc., in a low-temperature process at, for example, 150°C or less to prevent thermal damage to the support.

[0006] However, when a cured film is formed by a low-temperature process, the degree of curing of the cured film may be insufficient, and there is room for improvement in the light resistance of the cured film. Furthermore, according to the investigations of the present inventors, it has been found that even in the colored composition described in Patent Document 1, there is still room for further improvement in the light resistance of the obtained cured film.

[0007] Therefore, an object of the present invention is to provide a colored composition capable of forming a cured film having excellent light resistance. Another object of the present invention is to provide a cured film, a color filter, and a display device using the colored composition. [Means for solving the problem]

Furthermore, the present invention can provide a cured film, a color filter, and a display device using the colored composition. DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will be described in detail below. In the description of groups (atomic groups) in this specification, a notation that does not specify whether it is substituted or unsubstituted includes both groups (atomic groups) that have no substituents and groups (atomic groups) that have substituents. For example, the term "alkyl group" includes not only alkyl groups that have no substituents (unsubstituted alkyl groups) but also alkyl groups that have substituents (substituted alkyl groups). In this specification, unless otherwise specified, "exposure" includes not only exposure using light but also drawing using particle beams such as electron beams and ion beams. In addition, light used for exposure generally includes actinic rays or radiation such as the bright line spectrum of a mercury lamp, far ultraviolet light typified by excimer lasers, extreme ultraviolet light (EUV light), X-rays, and electron beams. In this specification, a numerical range expressed using "to" means a range that includes the numerical values ​​before and after "to" as the lower and upper limits. In this specification, the total solid content refers to the total mass of all components of the composition excluding the solvent. In this specification, a pigment means a colorant that is poorly soluble in a solvent. In this specification, a dye means a colorant that is easily soluble in a solvent. In this specification, "(meth)acrylate" refers to either or both of acrylate and methacrylate, "(meth)acrylic" refers to either or both of acrylic and methacrylic, "(meth)allyl" refers to either or both of allyl and methallyl, and "(meth)acryloyl" refers to either or both of acryloyl and methacryloyl. In this specification, the term "process" includes not only an independent process but also a process that cannot be clearly distinguished from other processes as long as the intended effect of the process is achieved. In this specification, the weight average molecular weight (Mw) and number average molecular weight (Mn) are defined as values ​​calculated in terms of polystyrene measured by gel permeation chromatography (GPC).

[0012] <Coloring composition> The coloring composition of the present invention is a coloring composition containing a colorant and a compound having an alicyclic epoxy group, The coloring composition is characterized in that, when the absorbance of light at a wavelength of 445 nm is taken as 1, the absorbance of the coloring composition at a wavelength of 535 nm is 17 or more.

[0013] The colored composition of the present invention can form a cured film having excellent light resistance. In particular, even when the cured film is formed at a low temperature of 150° C. or less (preferably 120° C. or less, and more preferably 100° C. or less), the cured film can have excellent light resistance.

[0014] Although the detailed reasons for such effects are unknown, it is presumed that they are due to the following. It is presumed that, when the coloring composition has the above-mentioned specific spectral characteristics and contains a compound having an alicyclic epoxy group, the curing of the coloring composition proceeds rapidly when the coloring composition is heated and cured, and as a result, a sufficiently cured cured film can be formed even when heated at a relatively low temperature. It is also presumed that, by containing a compound having an alicyclic epoxy group, the rigidity of the resulting cured film is improved, and deterioration of the cured film due to light irradiation can be more effectively suppressed. Furthermore, even if active species such as radicals are generated in the cured film by light irradiation, since the coloring composition has the above-mentioned spectral characteristics, it is presumed that the cured product derived from the compound having the alicyclic epoxy group and unreacted alicyclic epoxy groups will preferentially react with these generated active species, and it is presumed that deterioration of the colorant contained in the cured film can be suppressed. For these reasons, it is presumed that the coloring composition of the present invention can form a cured film with excellent light resistance.

[0015] Furthermore, by satisfying the above-described predetermined absorbance characteristics, this coloring composition can form a cured film suitable for blue pixels and the like, which has spectral characteristics that provide excellent color separation from other colors such as green.

[0016] The absorbance Aλ at a certain wavelength λ is defined by the following formula (Ab1): Aλ=-log(Tλ / 100) (Ab1) Aλ is the absorbance at wavelength λ, and Tλ is the transmittance (%) at wavelength λ.

[0017] When the absorbance of the coloring composition of the present invention is taken as 1 for light having a wavelength of 445 nm, the absorbance for light having a wavelength of 535 nm is 17 or more, preferably 19 or more, and more preferably 21 or more. The upper limit is not particularly limited, but can be 35 or less. In the present invention, the absorbance value may be a value measured in the state of a solution, or may be a value of a cured film formed using the coloring composition. When measuring the absorbance in the state of a cured film, it is preferable to apply the coloring composition to a support such as a glass substrate by a method such as spin coating, heat the composition at 100°C for 120 seconds using a hot plate or the like, then heat the composition at 150°C for 5 minutes using a hot plate or the like, and allow it to cool to room temperature to form a cured film having a thickness of 2.0 μm.

[0018] When a cured film having a thickness of 2.0 μm is formed using the colored composition of the present invention, the cured film preferably has an absorbance of 17 or more, more preferably 19 or more, and even more preferably 21 or more, for light having a wavelength of 535 nm, where the absorbance for light having a wavelength of 445 nm is taken as 1. The upper limit is not particularly limited, but can be 35 or less. The cured film is preferably a cured film having a thickness of 2.0 μm formed by the same method as in the measurement using the cured film described above.

[0019] The cured film preferably has a transmittance peak top in the wavelength range of 440 to 460 nm. The peak top is preferably in the wavelength range of 442 to 458 nm, and more preferably in the range of 445 to 455 nm. The cured film preferably has a maximum transmittance of 74% or more, more preferably 77% or more, and even more preferably 80% or more for light in the wavelength range of 440 to 460 nm. The average transmittance of the cured film for light in the wavelength range of 440 to 460 nm is preferably 70% or more, more preferably 74% or more, and even more preferably 78% or more.

[0020] Furthermore, the transmittance of the cured film to light with a wavelength of 445 nm is preferably 74% or more, more preferably 77% or more, and even more preferably 80% or more.

[0021] Furthermore, the transmittance of the cured film to light with a wavelength of 535 nm is preferably 12% or less, more preferably 10% or less, and even more preferably 8% or less.

[0022] Furthermore, the average transmittance of the cured film to light with a wavelength in the range of 530 to 550 nm is preferably 10% or less, more preferably 8% or less, and even more preferably 6% or less.

[0023] The epoxy group value of the total solid content of the colored composition of the present invention is preferably 0.2 to 5.0 mmol / g, and more preferably 0.2 to 2.0 mmol / g. The upper limit is preferably 4.8 mmol / g or less, more preferably 4.5 mmol / g or less, even more preferably 3.0 mmol / g or less, even more preferably 2.0 mmol / g or less, particularly preferably 1.8 mmol / g or less, and even more particularly preferably 1.6 mmol / g or less. The lower limit is preferably 0.4 mmol / g or more, more preferably 0.6 mmol / g or more, and even more preferably 0.9 mmol / g or more. The epoxy group value of the total solid content of the colored composition is calculated from the value derived from raw materials having epoxy groups among the raw materials that constitute the solid content of the colored composition. The raw material having an epoxy group may include a compound having an alicyclic epoxy group, a resin containing a repeating unit having an alicyclic epoxy group, and a compound having an epoxy group other than these, but it is preferable to include at least one of a compound having an alicyclic epoxy group and a resin containing a repeating unit having an alicyclic epoxy group. The compound having an alicyclic epoxy group and the resin containing a repeating unit having an alicyclic epoxy group will be described later. If the epoxy group value of the total solid content of the coloring composition is within the above range, the effect of excellent light resistance in the cured film can be expected. The epoxy group value of the total solid content of the coloring composition can be measured by methods such as near-infrared spectroscopy and Raman spectroscopy.

[0024] The colored composition of the present invention can be preferably used as a colored composition for forming pixels of a color filter, and more preferably used as a colored composition for forming blue pixels of a color filter.

[0025] The coloring composition of the present invention can be preferably used as a coloring composition for a display device. More specifically, it can be preferably used as a coloring composition for forming pixels of a color filter for a display device, and more preferably as a coloring composition for forming blue pixels of a color filter for a display device. The type of the display device is not particularly limited, and examples thereof include display devices having an organic semiconductor element as a light source, such as an organic electroluminescence display device.

[0026] The colored composition of the present invention can also be used as a colored composition for a solid-state imaging device. More specifically, it can be preferably used as a colored composition for forming pixels of a color filter for a solid-state imaging device, and more preferably used as a colored composition for forming blue pixels of a color filter for a solid-state imaging device.

[0027] It is also preferable that the colored composition of the present invention is used to form a cured film at a temperature of 150°C or less (preferably, a temperature of 120°C or less) throughout all steps. In this specification, forming a cured film at a temperature of 150°C or less throughout all steps means that all steps of forming a cured film using the colored composition are performed at a temperature of 150°C or less. As described above, when forming a cured film using a low-temperature process, achieving both heat resistance and light resistance (degree of curing) is an issue. However, in the case of a production method of forming a cured film using the colored composition of the present invention, all steps included in the method for producing a cured film can be applied at a temperature of 150°C or less (preferably, a temperature of 120°C or less).

[0028] The thickness of the cured film and pixels formed by the colored composition of the present invention is preferably 0.5 to 3.0 μm. The lower limit is preferably 0.8 μm or more, more preferably 1.0 μm or more, and even more preferably 1.1 μm or more.

Examples of the colorant include chromatic colorants such as blue, purple, red, green, yellow, and orange colorants. The colorant contained in the coloring composition preferably contains at least one colorant selected from blue and purple colorants, and more preferably contains a blue colorant. The total content of the blue and purple colorants in the total amount of colorants is preferably 50 to 100% by mass, more preferably 75 to 100% by mass, and even more preferably 90 to 100% by mass. The colorant preferably consists essentially of a blue colorant alone, or a combination of blue and purple colorants alone. In this specification, "the colorant consists essentially of a blue colorant alone" means that the content of the blue colorant in the total amount of colorants is 99% by mass or more, preferably 99.9% by mass or more, and even more preferably the colorant is blue colorant alone. Furthermore, in this specification, when the colorant substantially consists of only a blue colorant and a violet colorant, it means that the content of the blue colorant and the violet colorant in the total amount of the colorant is 99 mass% or more, preferably 99.9 mass% or more, and more preferably the colorant consists of only a blue colorant and a violet colorant.

[0032] The colorant may be a pigment or a dye. The pigment dissolves in 100 g of propylene glycol methyl ether acetate at 25° C. in an amount preferably less than 0.01 g, more preferably less than 0.005 g, and even more preferably less than 0.001 g.

The upper limit is preferably 180 nm or less, more preferably 150 nm or less, and even more preferably 100 nm or less. When the average primary particle diameter of the pigment is within the above range, the pigment has good dispersion stability in the coloring composition. In this specification, the primary particle diameter of the pigment can be determined from an image photograph obtained by observing the primary particles of the pigment with a transmission electron microscope. Specifically, the projected area of ​​the primary particles of the pigment is determined, and the corresponding circle-equivalent diameter is calculated as the primary particle diameter of the pigment. In addition, the average primary particle diameter in the present invention is the arithmetic mean value of the primary particle diameters of 400 primary particles of the pigment. Furthermore, the primary particles of the pigment refer to independent particles that are not aggregated.

[0034] The colorant preferably contains a pigment, and more preferably contains a pigment and a dye, because this allows for both high transmittance and high durability in the cured film. The pigment content in the colorant is preferably 35% by mass or more, more preferably 40% by mass or more, and even more preferably 45% by mass or more. Furthermore, because this allows for both high transmittance and high solvent resistance, the dye content is preferably 14.5 to 140 parts by mass per 100 parts by mass of the pigment.

[0036] A preferred embodiment of the pigment contained in the coloring composition is one in which the pigment is substantially composed of only a blue pigment. This embodiment makes it possible to obtain a cured film with even better heat resistance. In this specification, "substantially comprising only a blue pigment" means that the content of the blue pigment in the total amount of pigment is 99% by mass or more, preferably 99.9% by mass or more, and more preferably only a blue pigment.

[0037] Another preferred embodiment of the pigment contained in the coloring composition is one in which the pigment is substantially composed of only blue and violet pigments. This embodiment can suppress crystal growth of the pigments in the coloring composition, thereby further improving the storage stability of the coloring composition. In this specification, "substantially comprising only blue and violet pigments" means that the content of blue and violet pigments in the total amount of pigments is 99% by mass or more, preferably 99.9% by mass or more, and more preferably only blue and violet pigments. In this embodiment, the content of the violet pigment is preferably 1 to 60 parts by mass per 100 parts by mass of the blue pigment. The lower limit is preferably 5 parts by mass or more, more preferably 10 parts by mass or more. The upper limit is preferably 50 parts by mass or less, more preferably 40 parts by mass or less.

[0241] In the present invention, it is preferable to use an organic solvent with a low metal content, and the metal content of the organic solvent is preferably 10 mass ppb (parts per billion) or less. If necessary, a solvent with a mass ppt (parts per trillion) level may be used, and such a high-purity solvent is provided, for example, by Toyo Gosei Co., Ltd. (The Chemical Daily, November 13, 2015).

[0242] Methods for removing impurities such as metals from organic solvents include, for example, distillation (molecular distillation, thin-film distillation, etc.) and 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 material is preferably polytetrafluoroethylene, polyethylene, or nylon.

[0246] Furthermore, from the viewpoint of environmental regulations, the colored composition of the present invention preferably does not substantially contain environmentally restricted substances. In the present invention, "substantially free of environmentally restricted substances" means that the content of environmentally restricted substances in the colored composition is 50 ppm by mass or less, preferably 30 ppm by mass or less, more preferably 10 ppm by mass or less, and particularly preferably 1 ppm by mass or less. Examples of environmentally restricted substances include benzene; alkylbenzenes such as toluene and xylene; and halogenated benzenes such as chlorobenzene. These substances are registered as environmentally restricted substances under the REACH (Registration Evaluation Authorization and Restriction of Chemicals) regulations, the PRTR (Pollutant Release and Transfer Register) Act, and the VOC (Volatile Organic Compounds) regulations, and their usage amounts and handling methods are strictly regulated. These compounds may be used as solvents when producing the components used in the colored composition of the present invention, and may be mixed into the colored composition as residual solvents. From the viewpoints of human safety and environmental considerations, it is preferable to reduce the content of these substances as much as possible. Examples of methods for reducing environmentally regulated substances include heating or reducing the pressure in the system to a temperature above the boiling point of the environmentally regulated substance, thereby distilling off the environmentally regulated substance from the system. When distilling off a small amount of an environmentally regulated substance, it is also useful to perform azeotropy with a solvent having a boiling point equivalent to that of the solvent in question in order to increase efficiency. When a radically polymerizable compound is contained, a polymerization inhibitor or the like may be added prior to distillation under reduced pressure to prevent intermolecular crosslinking due to the progression of a radical polymerization reaction during distillation under reduced pressure.

[0282] <Method of producing colored composition> The colored composition of the present invention can be produced by mixing the above-mentioned components. When producing the colored composition, all components may be simultaneously dissolved and / or dispersed in a solvent to produce the colored composition, or, if necessary, each component may be prepared as two or more appropriate solutions or dispersions, which may be mixed at the time of use (at the time of application) to produce the colored composition.

[0283] The production of the coloring composition may also include a process for dispersing particles such as pigments. In the process for dispersing the pigment, mechanical forces used to disperse the pigment include compression, squeezing, impact, shear, and cavitation.

When grinding the pigment in a sand mill (bead mill), it is preferable to use small-diameter beads or increase the bead packing ratio to perform the process under conditions that increase grinding efficiency. After the grinding process, it is preferable to remove coarse particles by filtration, centrifugation, or the like. In addition, the process and disperser for dispersing pigments can be suitably described in "Dispersion Technology Encyclopedia," published by Joho Kiko Co., Ltd., July 15, 2005, or "Dispersion Technology and Industrial Applications Focused on Suspension (Solid / Liquid Dispersion Systems) - Comprehensive Data Collection," published by the Management Development Center Publishing Department, October 10, 1978, or in paragraph 0022 of JP 2015-157893 A.

Filters with different pore sizes within the above-mentioned range may also be combined. Furthermore, filtration with the first filter may be performed on only the dispersion, and filtration with the second filter may be performed after mixing with other components.

[0301] <Pixel formation method> A method for forming pixels will be described below: By using the colored composition of the present invention, for example, blue pixels can be formed.

[0302] The pixel formation method preferably includes a step of applying a coloring composition to a support to form a coloring composition layer, a step of patternwise exposing the coloring composition layer, and a step of developing the coloring composition layer after exposure. When forming pixels, it is preferable to perform all steps at a temperature of 150°C or lower. In the present invention, "performing all steps at a temperature of 150°C or lower" means that all steps of forming pixels using the coloring composition are performed at a temperature of 150°C or lower. When a further heating step is performed after developing the coloring composition layer after exposure, this heating step is also performed at a temperature of 150°C or lower. Each step will be described in detail below.

[0303] In the step of forming the coloring composition layer, the coloring composition is applied to a support to form the coloring composition layer. Examples of the support include a glass substrate, a polycarbonate substrate, a polyester substrate, an aromatic polyamide substrate, a polyamideimide substrate, and a polyimide substrate. An organic light-emitting layer may be formed on these substrates. An undercoat layer may also be provided on the substrate to improve adhesion with an upper layer, prevent diffusion of substances, or smooth the surface. The undercoat layer may be formed, for example, using a composition obtained by removing the colorant from the above-described coloring composition of the present invention. The surface contact angle of the undercoat layer is preferably 20 to 70° when measured with diiodomethane. Furthermore, it is preferably 30 to 80° when measured with water. A surface contact angle of the undercoat layer within the above range ensures good wettability of the resin composition. The surface contact angle of the undercoat layer can be adjusted, for example, by adding a surfactant.

[0304] The coloring 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 inkjet (for example, an on-demand method, a piezo method, a thermal method) and a nozzle jet printing method, flexographic printing, screen printing, gravure printing, reverse offset printing, and a metal mask printing method, a transfer method using a mold, and a nanoimprint method. The inkjet application method is not particularly limited, and examples thereof include the method described in "Expanding and Usable Inkjet - Infinite Possibilities Seen in Patents -", ​​published in February 2005 by Sumibe Techno Research (particularly pages 115 to 133), and the methods described in JP-A Nos. 2003-262716, 2003-185831, 2003-261827, 2012-126830, and 2006-169325. In addition, for the method of applying the coloring composition, the descriptions in WO 2017 / 030174 and WO 2017 / 018419 can be referred to, the contents of which are incorporated herein by reference.

[0305] The colored composition layer formed on the support may be dried (prebaked). When prebaking is performed, the prebaking temperature is preferably 80°C or less, more preferably 70°C or less, even more preferably 60°C or less, and particularly preferably 50°C or less. The lower limit can be, for example, 40°C or more. The prebaking time is preferably 10 to 3600 seconds. Prebaking can be performed using a hot plate, an oven, or the like.

[0306] 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.

[0307] 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 with wavelengths of 300 nm or more can also be used.

[0308] Furthermore, during exposure, light may be irradiated continuously or in pulses (pulse exposure). Pulse exposure is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, milliseconds or less). In the case of pulse exposure, the pulse width is preferably 100 nanoseconds (ns) or less, more preferably 50 nanoseconds or less, and even more preferably 30 nanoseconds or less. There is no particular limitation on the lower limit of the pulse width, but it can be 1 femtosecond (fs) or more, and can also be 10 femtoseconds or more. The frequency is preferably 1 kHz or more, more preferably 2 kHz or more, and even more preferably 4 kHz or more. The upper limit of the frequency is preferably 50 kHz or less, more preferably 20 kHz or less, and even more preferably 10 kHz or less. The maximum instantaneous irradiance is 50,000,000 W / m 2 Preferably, it is 100,000,000 W / m or more. 2 More preferably, it is 200,000,000 W / m or more. 2 It is more preferable that the upper limit of the maximum instantaneous illuminance is 1,000,000,000 W / m 2 Preferably, it is 800,000,000 W / m or less. 2 More preferably, it is 500,000,000 W / m or less. 2 It is more preferable that the pulse width is equal to or less than 1 / 2 s. The pulse width refers to the time during which light is irradiated in a pulse period. The frequency refers to the number of pulse periods per second. The maximum instantaneous irradiance refers to the average irradiance during the time during which light is irradiated in a pulse period. The pulse period refers to the period during which light irradiation and pauses occur in pulse exposure.

[0309] The irradiation amount (exposure amount) is, for example, 0.03 to 2.5 J / cm 2 The lower limit is preferably 0.05 J / cm 2 It is preferable that the concentration is 0.2 J / cm or more. 2 More preferably, it is 0.5 J / cm or more. 2 More preferably, it is 0.8 J / cm or more.2 More preferably, it is 1.0 J / cm or more. 2 The upper limit is 2.0 J / cm. 2 Preferably, it is 1.5 J / cm or less. 2 The exposure illuminance can be set appropriately, for example, to 50 mW / cm or less. 2 ~10W / cm 2 The lower limit of the exposure illuminance is preferably 500 mW / cm. 2 It is preferable that the power is 800 mW / cm or more. 2 More preferably, it is 1000 mW / cm or more. 2 The upper limit of the exposure illuminance is 10 W / cm or more. 2 Preferably, it is 7 W / cm or less. 2 More preferably, it is 5 W / cm or less. 2 It is more preferable that:

[0310] The oxygen concentration during exposure can be selected appropriately. In addition to being performed in the atmosphere, exposure can 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 oxygen concentration and exposure illuminance can be appropriately combined, for example, an oxygen concentration of 10% by volume and an illuminance of 1 W / cm 2 , oxygen concentration 35% by volume, illuminance 2W / cm 2 etc.

[0311] In addition, light with a wavelength of more than 350 nm and less than 380 nm (preferably i-line) is used at 1 J / cm 2 It is also preferable to perform exposure by irradiating with the above exposure amount. By exposing in this manner, the colored composition layer can be sufficiently cured, and pixels with better light resistance can be produced.

[0312] Next, the coloring composition layer after exposure is developed. That is, 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 coloring composition layer in the unexposed portions in the exposure step is 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. Furthermore, to improve residue removability, the process of shaking off the developer every 60 seconds and then supplying fresh developer may be repeated several times.

[0313] Examples of the developer include organic solvents and alkaline developers, with alkaline developers being preferred. The alkaline developer is preferably an alkaline aqueous solution (alkaline developer) prepared by diluting an alkaline agent with pure water. Examples of the alkaline agent 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 high 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, more preferably 0.01 to 1% by mass. The developer may further contain a surfactant. Examples of the surfactant include those described above, with nonionic surfactants being preferred. The developer may be prepared as a concentrated solution and then diluted to the required concentration for use, for ease of transportation and storage. 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 preferable to wash (rinse) the developed layer with pure water. Rinsing is preferably performed by supplying a rinse solution to the developed colored composition layer while rotating the support on which the developed colored composition layer is formed. It is also preferable to perform this by moving the nozzle ejecting the rinse solution from the center of the support to the periphery of the support. In this case, the nozzle movement speed may be gradually reduced as the nozzle moves from the center to the periphery of the support. Rinsing in this manner can suppress in-plane variations in rinsing. The same effect can also be obtained by gradually decreasing the rotation speed of the support while moving the nozzle from the center to the periphery of the support.

[0314] After development and drying, it is also preferable to carry out additional exposure treatment or heat treatment (post-baking). The additional exposure treatment and post-baking are hardening treatments after development to ensure complete hardening.

[0315] When post-baking is performed, the heating temperature is preferably 150°C or lower. The upper limit of the heating temperature is more preferably 120°C or lower, and even more preferably 100°C or lower. The lower limit of the heating temperature is not particularly limited as long as it can promote film curing, but is preferably 50°C or higher, and more preferably 75°C or higher. The heating time is preferably 1 minute or longer, more preferably 5 minutes or longer, and even more preferably 10 minutes or longer. The upper limit is not particularly limited, but from the perspective of productivity, 20 minutes or shorter is preferred. Post-baking is also preferably performed in an inert gas atmosphere. According to this embodiment, thermal polymerization can proceed with extremely high efficiency without being inhibited by oxygen. Even when pixels are produced at temperatures of 150°C or lower throughout the entire process, pixels with good flatness and excellent properties such as light resistance can be produced. Examples of inert gases include nitrogen gas, argon gas, and helium gas, and nitrogen gas is preferred. The oxygen concentration during post-baking is preferably 100 ppm or lower.

[0316] When performing additional exposure treatment, it is preferable to expose by irradiating with light having a wavelength of 254 to 350 nm. In a more preferred embodiment, the step of patternwise exposing the coloring composition layer (exposure before development) is performed by irradiating the coloring composition layer with light having a wavelength of more than 350 nm and not more than 380 nm (preferably light having a wavelength of 355 to 370 nm, more preferably i-line), and the additional exposure treatment (exposure after development) is performed by irradiating the coloring composition layer after development with light having a wavelength of 254 to 350 nm (preferably light having a wavelength of 254 nm). According to this embodiment, the coloring composition layer can be moderately cured by the first exposure (exposure before development), and the entire coloring composition layer can be almost completely cured by the next exposure (exposure after development). As a result, even under low-temperature conditions, the coloring composition layer can be sufficiently cured to form pixels with excellent properties such as light resistance, adhesion, and rectangularity. When performing exposure in two stages like this, the coloring composition is preferably a photopolymerization initiator having an extinction coefficient of 1.0 × 10 at a wavelength of 365 nm in methanol. 3 mL / g cm or more and an extinction coefficient of 1.0×10 at 365 nm in methanol. 2 mL / g cm or less, and the absorption coefficient at a wavelength of 254 nm is 1.0 × 10 3 It is preferable to use a photopolymerization initiator A2 containing a photopolymerization initiator A2 of at least mL / g cm.

[0317] The exposure after development can be carried out using, for example, an ultraviolet photoresist curing device, which may irradiate not only light with a wavelength of 254 to 350 nm but also other light (for example, i-line).

[0318] Furthermore, the exposure source spectrum when performing additional exposure treatment is preferably a continuous spectrum, and from the viewpoint of improving the light resistance and adhesion to the substrate of the resulting cured film, it preferably has a spectral distribution different from that of the exposure before development, and examples thereof include the following radiations (a) to (c). Among these, radiations (b) and (c) are preferred in that they can achieve a higher level of improvement in the light resistance and adhesion to the substrate of the resulting cured film. Furthermore, when the colorant contains a dye, radiation (c) is preferred because it has fewer high-intensity components on the short-wavelength side, since dyes generally absorb ultraviolet light or short-wavelength visible light and may be photodecomposed. (a) Radiation having a spectral distribution different from that of the exposure light before development, in which the peak intensity at a wavelength of 313 nm (j-line) is 1 / 6 or more and less than 1 / 3 of the peak intensity at a wavelength of 365 nm (i-line). (b) Radiation having a spectral distribution different from that of the exposure light before development, and having a peak intensity at a wavelength of 313 nm (j-line) that is at least one-third of the peak intensity at a wavelength of 365 nm (i-line).

Definitions of display devices and details of each display device are described, for example, in "Electronic Display Devices" (written by Akio Sasaki, published by Kogyo Chosakai Co., Ltd. in 1990) and "Display Devices" (written by Nobuaki Ibuki, published by Sangyo Tosho Co., Ltd. in 1989). Liquid crystal display devices are described, for example, in "Next Generation Liquid Crystal Display Technology" (edited by Tatsuo Uchida, published by Kogyo Chosakai Co., Ltd. in 1994). There are no particular limitations on the liquid crystal display device to which the present invention can be applied, and the present invention can be applied to various types of liquid crystal display devices described in the above-mentioned "Next Generation Liquid Crystal Display Technology."

[0322] The organic electroluminescence display device may also be a microdisplay. The diagonal length of the display surface of the microdisplay may be, for example, 4 inches or less, 2 inches or less, 1 inch or less, or 0.2 inches or less. Applications of the microdisplay are not particularly limited, but include electronic viewfinders, smart glasses, and head-mounted displays.

[0323] The organic electroluminescent display device may have a light source composed of a white organic electroluminescent element. The white organic electroluminescent element preferably has a tandem structure. Tandem structures of organic electroluminescent elements are described in, for example, JP 2003-045676 A and Akiyoshi Mikami, "The Frontline of Organic EL Technology Development - High Brightness, High Precision, Long Life, and Know-How Collection," Technical Information Association, pp. 326-328, 2008. The spectrum of white light emitted by the organic EL element preferably has strong maximum emission peaks in the blue region (430-485 nm), green region (530-580 nm), and yellow region (580-620 nm). In addition to these emission peaks, an organic EL element that also has a maximum emission peak in the red region (650-700 nm) is more preferred.

[0324] The organic electroluminescent display device may have a color filter. The color filter may be provided on a base layer. In an organic electroluminescent display device that combines a color filter and a white organic electroluminescent element to extract light of three primary colors, transparent pixels may be provided and the white light may be used directly for emission. This can also increase the brightness of the display device. The organic electroluminescent display device may have a lens on the color filter. The lens may have various shapes derived from optical system design, such as a convex shape or a concave shape. For example, a concave shape (concave lens) can easily improve the light collection ability. The lens may be in direct contact with the color filter, or another layer, such as an adhesion layer or a planarization layer, may be provided between the lens and the color filter. The lens may also be arranged and used in the manner described in International Publication No. 2018 / 135189.

[0325] <Solid-state imaging element> The colored composition and cured film of the present invention can also be used in a solid-state imaging device. The configuration of the solid-state imaging device is not particularly limited as long as it functions as a solid-state imaging device, and examples thereof include the following configurations.

[0326] The substrate includes a plurality of photodiodes constituting the 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 formed 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 being open. A device protection film formed 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 formed on the device protection film. Furthermore, a light-collecting means (e.g., a microlens, etc.; the same applies hereinafter) may be formed on the device protection film below the color filter (on the side closer to the substrate), or on the color filter. The pixels of the color filter may be embedded in spaces partitioned by partitions, for example, in a grid pattern. In this case, the refractive index of the partitions is preferably lower than that of the pixels. Examples of imaging devices having such a structure include those described in Japanese Patent Laid-Open No. 2012-227478, Japanese Patent Laid-Open No. 2014-179577, International Publication No. 2018 / 043654, and U.S. Patent Application Publication No. 2018 / 0040656.

[0345] <Evaluation> (Formation of hardened film) Each coloring composition was applied to a glass substrate using a spin coater (manufactured by Mikasa Co., Ltd.) to form a coating film. Then, a heat treatment (pre-baking) was performed for 120 seconds using a hot plate at 100°C so that the dry thickness of the coating film would be 2.0 μm. Next, a heat treatment (post-baking) was performed at 150°C for 5 minutes to harden the coating film and form a cured film.

[0346] (Evaluation of absorbance ratio) The absorption spectrum of the cured film formed above was measured in the wavelength range of 400 to 700 nm using a spectrophotometer (U-4100, manufactured by Hitachi High-Technologies Corporation), and the absorbance A at a wavelength of 535 nm was calculated based on the absorbance at a wavelength of 445 nm taken as 1. 535 was calculated.

[0347] (Lightfastness) The glass substrate on which the cured film was formed was subjected to a light resistance test using a light resistance tester (SX-75 manufactured by Suga Test Instruments Co., Ltd.) at a black panel temperature of 63°C, a quartz inner filter, a 275 nm cut outer filter, and an illuminance of 75 mW / m 2A light resistance test was carried out for 50 hours under conditions of wavelengths from 300 to 400 nm and humidity of 50%. The spectral transmittance of the cured film was measured before and after the light resistance test using a spectrophotometer MCPD-3700 (manufactured by Otsuka Electronics Co., Ltd.). The change in transmittance at a wavelength of 445 nm (ΔT) was calculated and the light resistance was evaluated according to the following criteria. Change in transmittance (ΔT) = |Transmittance at a wavelength of 445 nm of the cured film before light resistance test - Transmittance at a wavelength of 445 nm of the cured film after light resistance test| S: ΔT is 1% or less A: ΔT is greater than 1% and less than 2.5% B: ΔT is greater than 2.5% and less than 4% C: ΔT is greater than 4% and less than 5% D: ΔT is greater than 5%

[0348] The evaluation results of the absorbance ratio and light resistance are shown in the table below. The epoxy group value of the total solid content of the colored composition is also shown in the table below. The epoxy group value of the total solid content of the colored composition was calculated from the structural formula of the raw material having an epoxy group.

[0349] [Table 4]

[0350] As shown in the table above, the coloring compositions of the Examples were able to form cured films with excellent light resistance. Furthermore, the cured films obtained using the coloring compositions of the Examples had better spectral characteristics as blue pixels than the cured films obtained using the coloring compositions of the Comparative Examples, and were superior in sensitivity as blue pixels. Furthermore, the cured films obtained using the coloring compositions of the Examples also had better color separation from green than the cured films obtained using the coloring compositions of the Comparative Examples.

[0351] For the colored compositions of Examples 1 and 14, instead of heat treatment (post-baking) at 150°C for 5 minutes, a UV photoresist curing device (UMA-802-HC-552; manufactured by Ushio Electric Co., Ltd.) was used to cure the colored compositions with 3000 mJ / cm 2A cured film was formed in the same manner as above, except that the exposure was carried out at an exposure amount of 1000 ppm. The light resistance of this cured film was evaluated in the same manner as above, and it was rated as S.

[0352] A cured film was formed in the same manner as above, except that the colored composition of Example 1 was subjected to a 20-minute heat treatment (post-bake) using a hot plate at 100° C. instead of a 5-minute heat treatment (post-bake) at 150° C. The light resistance of this cured film was evaluated in the same manner as above, and it was rated as S.

[0353] Regarding the colored composition of Example 1, instead of heat treatment (post-baking) at 150°C for 5 minutes, an i-line stepper exposure system FPA-3000i5+ (manufactured by Canon Inc.) was used to expose the colored composition to 1500 mJ / cm 2 A cured film was prepared in the same manner except that the exposure was carried out at an exposure dose of 1000 ppm. The light resistance of this cured film was evaluated in the same manner as above, and it was rated as S.

[0354] (Example 1001) The green pixel-forming coloring composition was applied to 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. Next, an i-line stepper exposure system FPA-3000i5+ (Canon Inc.) was used to apply 1000 mJ / cm 2 The substrate was exposed to light at 1000 W at 2000 W through a mask with a 2 μm square dot pattern. Next, puddle development was performed using a 0.3 mass % aqueous solution of tetramethylammonium hydroxide (TMAH) at 23°C for 60 seconds. After that, the substrate was rinsed with a spin shower and further washed with pure water. Next, a green colored pattern (green pixel) was formed by heating at 150°C for 5 minutes using a hot plate. Similarly, a colored composition for forming a red pixel and a colored composition for forming a blue pixel were sequentially patterned to form a red colored pattern (red pixel) and a blue colored pattern (blue pixel), respectively, thereby forming a structure. The colored composition of Example 1 was used as the colored composition for forming a blue pixel. As the coloring composition for forming a green pixel, coloring compositions 1 to 8 for forming a green pixel, which will be described later, were used. As the coloring composition for forming red pixels, a coloring composition 1 for forming red pixels, which will be described later, was used.
