Quantum yield (QY) = Number of photons emitted from the sample / Number of photons absorbed by the sample. To improve the outcoupling efficiency from quantum-size materials, such as optical films containing semiconductor light-emitting nanoparticles, several methods have been proposed, including incorporating scattering particles into the film and / or adjacent films, lowering the refractive index of the film by incorporating hollow silica particles, and arranging structures of appropriate shapes (cf. Proceedings of SPIE, P.184, 5519-33, 2004). Among these, arranging a structured film on top of a quantum material-containing film is ideal for large-screen TV applications that achieve high dynamic range by applying local dimming techniques. Scattering particles are detrimental to dimming techniques because scattered light causes chromatic aberration, and the limited volume of hollow silica particles makes it difficult to sufficiently lower the refractive index of the film to a practical level. A combination of lowering the refractive index and arranging a structured film can also be applied. 【0075】 - Bank composition (second composition) Bank (150) is at least (I) Alkali-soluble polymer, (II) polymerization initiators, and (III) Compounds containing at least two (meth)acryloyloxy groups, A cured layer obtained from or obtainable from a second composition comprising, preferably, a photosensitive composition, preferably, the at least two (meth)acryloyloxy groups being two or more acryloyloxy groups, methacryloyloxy groups, or a combination thereof, preferably, the total amount of the compound containing the at least two (meth)acryloyloxy groups based on the total amount of alkali-soluble polymer being in the range of 5 wt.% to 1,000 wt.%, more preferably 10 wt.% to 500 wt.%.

In order to form a crosslinked structure, a compound containing two or more reactive groups, either acryloyloxy groups or methacryloyloxy groups, is required, and to form a higher-order crosslinked structure, it is preferable to contain three or more acryloyloxy groups or methacryloyloxy groups.

The alkali-soluble polymer used in the present invention preferably has an acryloyl group. Furthermore, while the alkali-soluble polymer used in the present invention is not particularly limited, it is preferably selected from polysiloxanes and (meth)acrylate polymers containing siloxane bonds in their main skeleton. Among these, the use of methacrylate polymers, acrylate polymers, or combinations thereof is more preferable, and acrylate polymers are even more preferable. The alkali-soluble polymer used in the present invention may have carboxyl groups. Having carboxyl groups can improve the solubility of the alkali-soluble polymer in low-concentration developers. In accordance with the present invention, the term "alkali-soluble polymer" means a polymer that is soluble in a 2.38% TMAH aqueous solution at 23.0 ± 0.1°C. 【0082】 -(meth)acrylate polymer In this specification, (meth)acrylate is a general term for acrylate and methacrylate. In the present invention, when using a low-concentration developer and / or applying a low curing temperature, it is preferable to use one or more (meth)acrylate polymers. The alkali-soluble polymer used in the present invention may be selected from commonly used methacrylate polymers, acrylate polymers, or combinations thereof, and more preferably is an acrylic polymer such as polyacrylic acid, polymethacrylic acid, polyalkyl acrylate, or polyalkyl methacrylate. The acrylic polymer used in the present invention preferably contains repeating units containing acryloyl groups, and more preferably contains repeating units containing carboxyl groups and / or repeating units containing alkoxysilyl groups. 【0083】 The repeating unit containing a carboxyl group is not particularly limited as long as it is a repeating unit containing a carboxyl group in the side chain, but a repeating unit derived from an unsaturated carboxylic acid, an unsaturated carboxylic anhydride or a mixture thereof is preferred. The repeating unit having an alkoxysilyl group may be a repeating unit having an alkoxysilyl group in the side chain, but is preferably a repeating unit derived from the monomer represented by the following formula (B). X B -(CH2) a -Si(OR B ) b (CH3) 3-b (B) Here, X B is a vinyl group, a styryl group or a (meth)acryloyloxy group, R B is a methyl group or an ethyl group, a is an integer of 0 to 3, and b is an integer of 1 to 3. 【0084】 Furthermore, it is preferable that the above polymer contains a repeating unit containing a hydroxyl group derived from a hydroxyl group-containing unsaturated monomer. The weight average molecular weight of the alkali-soluble polymer according to the present invention is not particularly limited, but is preferably from 1,000 to 100,000, more preferably from 1,200 to 80,000, still more preferably from 1,000 to 40,000, and still more preferably from 2,000 to 30,000. Here, the weight average molecular weight is the weight average molecular weight in terms of polystyrene by gel permeation chromatography.

For example, a polymer (C6H10O3.C6H7NO3.C5H8O2.C4H6O2)x (CAS Registry Number 1615232-03-05) having 2-propenoic acid, 2-methyl-, 2-hydroxyethyl 2-methyl-2-propenoic acid, 2-isocyanatoethyl 2-propenoic acid, and methyl 2-methyl-2-propenoic acid is preferably used. 【0085】 - Polysiloxane The alkali-soluble polymer preferably contains a siloxane (Si - O - Si) bond as the main skeleton. In the present invention, a polymer containing a siloxane bond as the main skeleton is called a polysiloxane. The skeletal structure of polysiloxane can be classified as follows according to the number of oxygen atoms bonded to the silicon atom. Silicon skeleton (the number of oxygen atoms bonded to the silicon atom is 2), silsesquioxane skeleton (the number of oxygen atoms bonded to the silicon atom is 3), silica skeleton (the number of oxygen atoms bonded to the silicon atom is 4). In the present invention, any of these may be used. The polysiloxane molecule may contain a plurality of combinations of these skeletal structures. The polysiloxane used in the present invention preferably contains a silsesquioxane skeleton. 【0086】 Polysiloxanes generally have silanol groups or alkoxysilyl groups. These silanol and alkoxysilyl groups refer to hydroxyl and alkoxy groups directly bonded to the silicon that forms the siloxane skeleton. Here, the silanol and alkoxysilyl groups are thought to promote the curing reaction when forming a cured film using the composition, as well as to contribute to the reaction with silicon-containing compounds described later. Therefore, it is preferable that polysiloxanes have these groups. Such polysiloxanes and / or (meth)acrylate polymers that are publicly available may preferably be used. Alternatively, polysiloxanes and / or (meth)acrylate polymers, such as those disclosed in WO2021 / 018972A1, may preferably be used. In some embodiments, a mixture of polysiloxane and acrylic polymer may be used as an alkali-soluble polymer. 【0087】 Furthermore, a cured film is formed by coating the composition of the present invention onto a substrate, exposing it to an image, and developing it. At this time, there needs to be a difference in solubility between the exposed and unexposed areas, and the coating film in the unexposed area needs to have a certain level of solubility in the developer. For example, if the dissolution rate of the prebaked coating film in a 2.38% tetramethylammonium hydroxide (hereinafter sometimes abbreviated as TMAH) aqueous solution (hereinafter sometimes referred to as alkali dissolution rate or ADR; details will be described later) is 50 Å / second or more, it is considered that a pattern can be formed by exposure and development. However, since the required solubility differs depending on the film thickness of the cured film to be formed and the development conditions, it is necessary to appropriately select an alkali-soluble polymer according to the development conditions. Depending on the type and amount of photosensitizer or silanol catalyst contained in the composition, for example, when the film thickness is 0.1 to 100 μm (1,000 to 1,000,000 Å), the dissolution rate in a 2.38% TMAH aqueous solution is preferably 50 to 20,000 Å / second, more preferably 100 to 10,000 Å / second. 【0088】 [Method for measuring and calculating the alkali dissolution rate (ADR)] Using an aqueous TMAH solution as the alkaline solution, the alkali dissolution rate of the alkali-soluble polymer is measured and calculated as follows. The alkali-soluble polymer was diluted to 35% by mass with propylene glycol monomethyl ether acetate (hereinafter referred to as PGMEA) and dissolved in a stirrer at room temperature for 1 hour. In a cleanroom at a temperature of 23.0±0.5℃ and a humidity of 50±5.0%, 1 cc of the prepared alkali-soluble polymer solution was dropped onto the center of a 525 μm thick 4-inch silicon wafer using a pipette, and a film with a thickness of 2±0.1 μm was prepared by spin coating. The film was then heated on a hot plate at 100℃ for 90 seconds to remove the solvent. The film thickness of the coated film was measured using a spectroscopic ellipsometer (JAWoollam). 【0089】 Next, a silicon wafer bearing this film is gently immersed in a 6-inch diameter glass petri dish containing 100 ml of a predetermined concentration of TMAH aqueous solution adjusted to 23.0 ± 0.1°C, and then left to stand. The time until the coating film disappears is measured. The dissolution rate is determined by dividing this by the time it takes for the film to disappear in the area 10 mm inward from the wafer edge. In cases where the dissolution rate is extremely slow, the wafer is immersed in a TMAH aqueous solution for a certain period of time, then heated on a 200°C hot plate for 5 minutes to remove water incorporated into the film during the dissolution rate measurement. After that, the film thickness is measured, and the dissolution rate is calculated by dividing the change in film thickness before and after immersion by the immersion time. The above measurement method is performed 5 times, and the average value obtained is taken as the dissolution rate of the alkali-soluble polymer. 【0090】 - Polymerization initiator The composition according to the present invention contains a polymerization initiator. The polymerization initiator includes polymerization initiators that generate acids, bases, or radicals by radiation, and polymerization initiators that generate acids, bases, or radicals by heat. In the present invention, the reaction starts immediately after irradiation and the reheating process before the post-irradiation development process can be omitted, so from the viewpoint of shortening the process and cost, the former is preferred, and photoradical generators are more preferred. Photoradical generators can improve resolution by enhancing pattern shape or increasing development contrast. The photoradical generator used in this invention is a photoradical generator that releases radicals upon irradiation with radiation. Here, examples of radiation include visible light, ultraviolet light, infrared light, X-rays, electron beams, alpha rays, and gamma rays. 【0091】 The optimal amount of photoradical generator to be added depends on the type and amount of active substances generated by the decomposition of the photoradical generator, the required photosensitivity, and the required dissolution contrast between the exposed and unexposed areas. However, based on the total mass of the alkali-soluble polymer, the optimal amount is preferably 0.001 to 50% by mass, more preferably 0.01 to 30% by mass. If the amount added is less than 0.001% by mass, the dissolution contrast between the exposed and unexposed areas may be too low, and the additive effect may not be achieved. On the other hand, if the amount of photoradical generator added exceeds 50% by mass, cracks may occur in the formed coating film, and discoloration due to the decomposition of the photoradical generator may become noticeable, which may reduce the colorless transparency of the coating film. Furthermore, if the amount added is too high, thermal decomposition of the photoradical generator may cause decomposition of the electrical insulation properties of the cured product and gas release, which may cause problems in subsequent processes. In addition, the resistance of the coating film to photoresist removers mainly composed of monoethanolamine may decrease. 【0092】 Examples of photoradical generators include azo-based, peroxide-based, acylphosphine oxide-based, alkylphenone-based, oxime ester-based, and titanocene-based initiators. Among these, alkylphenone-based, acylphosphine oxide-based, and oxime ester-based initiators are preferred, as well as 2,2-dimethoxy-1,2-diphenylethane-1-one, 1-hydroxycyclohexylphenyl ketone, 2-hydroxy-2-methyl-1-phenylpropan-1-one, 1-[4-(2-hydroxyethoxy)phenyl]-2-hydroxy-2-methyl-1-propan-1-one, 2-hydroxy-1-{4-[4-(2-hydroxy-2-methylpropionyl)-benzyl]phenyl}-2-methylpropan-1-one, and 2-methyl-1-(4-methylthiophenyl)-2-morpholinopropan- This includes compounds such as 1-one, 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-1-butanone, 2-(dimethylamino)-2-[(4-methylphenyl)methyl]-1-[4-(4-morpholinyl)-phenyl]-1-butanone, 2,4,6-trimethylbenzoyldiphenylphosphine oxide, bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide, 1,2-octanedione, 1-[4-(phenylthio)-2-(O-benzoyl oxime)], ethanone, and 1-[9-ethyl-6-(2-methylbenzoyl)-9H-carbazol-3-yl]-1-(O-acetyloxime). 【0093】 - Surfactants Furthermore, compositions according to the present invention may optionally contain a surfactant.

Preferred adhesion enhancers include imidazoles and silane coupling agents. Among the imidazoles, 2-hydroxybenzimidazole, 2-hydroxyethylbenzimidazole, benzimidazole, 2-hydroxyimidazole, imidazole, 2-mercaptoimidazole, and 2-aminoimidazole are preferred, and 2-hydroxybenzimidazole, benzimidazole, 2-hydroxyimidazole, and imidazole are particularly preferred.

Details regarding (meth)acrylate monomers, other materials, polymers, and scattering particles are described in the sections "(meth)acrylate monomers," "other materials," "polymers," and "scattering particles." 【0117】 The additional additives described in the "Additives" section may be mixed. In accordance with the present invention, it is desirable not to add a solvent in order to achieve large-area inkjet printing with improved uniformity, without causing nozzle clogging, and / or with good dispersibility of semiconductor light-emitting nanoparticles and / or good dispersibility of scattering particles. In another aspect, the present invention also relates to a method for manufacturing a color conversion device (100) comprising at least the following steps, preferably in this order: Xi) To provide a second composition on the surface of the support medium. Xii) Curing the second composition, Xiii) Applying photopatterning to the composition to be cured to create banks and patterned pixel regions. Xiv) Preferably by inkjet, provide the first composition to at least one pixel region, Xv) The first composition is cured, preferably the color conversion device (100) further containing a support medium (170). Y) Optionally, photocuring of (meth)acrylate monomer by UV light irradiation is applied. 【0118】 - Bank creation process (1) Coating process First, the above composition is applied to a substrate. The formation of a coating film of the composition according to the present invention may be carried out by any conventionally known method for applying a photosensitive composition. Specifically, it may be freely selected from dip coating, roll coating, bar coating, brush coating, spray coating, doctor coating, flow coating, spin coating, slit coating, etc. Furthermore, as the substrate to which the composition is applied, a suitable substrate such as a silicon substrate, a glass substrate, or a resin film may be used. Various semiconductor devices may be formed on these substrates as needed. If the substrate is a film, gravure coating may also be used. If desired, a drying process may be added after the film has been applied. Also, if necessary, the application process may be repeated once or two or more times to achieve the desired film thickness of the coating film to be formed. 【0119】 (2) Pre-bake process After applying the composition to form a coating film, it is preferable to dry the coating film and then pre-bake (heat treat) the coating film to reduce the amount of residual solvent in the coating film. The pre-bake process can usually be carried out at a temperature of 50 to 150°C, preferably 90 to 120°C, and involves heating for 10 to 300 seconds, preferably 30 to 120 seconds, on a hot plate, or for 1 to 30 minutes in a clean oven. 【0120】 (3) Exposure process After forming the coating film, the surface of the coating film is then irradiated with light. Any light source conventionally used in pattern formation methods may be used for light irradiation. Such light sources include high-pressure mercury lamps, low-pressure mercury lamps, metal halide lamps, xenon lamps, laser diodes, LEDs, etc. Ultraviolet light such as g-rays, h-rays, and i-rays is usually used as the irradiation light. Except for ultrafine processing of semiconductors, it is common to use light of 360 to 430 nm (high-pressure mercury lamps) for patterning of several micrometers to tens of micrometers. The energy of the irradiation light depends on the light source and the thickness of the coating film, but is usually 5 to 2000 mJ / cm². 2 Preferably 10 to 1000 mJ / cm² 2 The irradiation light energy is 5 mJ / cm². 2 If the irradiation light energy is less than 2000 mJ / cm², sufficient resolution may not be obtained. On the other hand, if the irradiation light energy is 2000 mJ / cm², sufficient resolution may not be obtained. 2 If the exposure level exceeds a certain point, it can lead to excessive exposure and cause halation. A general-purpose photomask may be used to irradiate the pattern shape with light. Such a photomask may be freely selected from known ones. The irradiation environment is not particularly limited and can usually be in the atmosphere (air) or a nitrogen atmosphere. Furthermore, when a film is formed on the entire surface of the substrate, the entire surface of the substrate may be irradiated with light. In this invention, the pattern film also includes the case where a film is formed on the entire surface of the substrate. 【0121】 (4) Post-exposure bake process After exposure, a post-exposure bake may be performed as needed to promote the reaction between polymers in the film by the polymerization initiator. Unlike the heating process (6) described later, this heat treatment is not performed to completely cure the coating film, but rather to leave only the desired pattern on the substrate after development, allowing the other areas to be developed and removed. Therefore, it is not essential in the present invention. 【0122】 When post-exposure baking is performed, a hot plate, oven, furnace, etc., may be used. Since it is undesirable for acids, bases, and radicals generated in the exposed area by light irradiation to diffuse into the unexposed area, the heating temperature should not be too high. From this viewpoint, the heating temperature range after exposure is preferably 40 to 150°C, and more preferably 60 to 120°C. Stepwise heating can be applied as needed to control the curing rate of the composition. The atmosphere during heating is not particularly limited and may be selected from inert gases such as nitrogen, under vacuum, under reduced pressure, or in oxygen gas, etc., for the purpose of controlling the curing rate of the composition. Furthermore, the heating time is preferably above a certain level in order to maintain a higher degree of uniformity of the temperature history within the wafer surface, and is preferably not excessively long in order to suppress the diffusion of generated acids, bases, or radicals. From this viewpoint, the heating time is preferably 20 to 500 seconds, and more preferably 40 to 300 seconds. 【0123】 (5) Development process After exposure, a post-exposure bake is optionally performed, and then the coating film is developed. Any developer conventionally used for developing photosensitive compositions may be used as the developer during development. Preferred developers include alkaline developers which are aqueous solutions of alkaline compounds such as tetraalkylammonium hydroxide, choline, alkali metal hydroxide, alkali metal metasilicate (hydrate), alkali metal phosphate (hydrate), aqueous sodium carbonate, ammonia, alkylamines, alkanolamines, and heterocyclic amines. Particularly preferred alkaline developers are aqueous tetramethylammonium hydroxide, aqueous potassium hydroxide, aqueous sodium hydroxide, and aqueous sodium carbonate. In this alkaline developer, water-soluble organic solvents such as methanol and ethanol, or surfactants may be further contained as needed. In the present invention, development may be carried out using a developer at a lower concentration than the 2.38% by mass TMAH developer commonly used as a developer. Such developing solutions include 0.05 to 1.5% by mass TMAH aqueous solution, 0.1 to 2.5% by mass sodium carbonate aqueous solution, 0.01 to 1.5% by mass potassium hydroxide aqueous solution, etc. The development time is usually 10 to 300 seconds, preferably 30 to 180 seconds. The development method may also be freely selected from conventionally known methods. Specifically, methods such as immersion in the developing solution (dip), paddle, shower, slit, cap coat, and spray are included. After developing the developing solution to obtain the pattern, it is preferable to rinse with water. 【0124】 (6) Heating process After development, the obtained pattern film is heat-cured. The same heating device used in the post-exposure bake described above may be used for the heating process. The heating temperature in this heating process is not particularly limited as long as it is a temperature at which the coating film can be cured, and may be freely determined. However, if silanol groups of polysiloxane remain, the chemical resistance of the cured film may become insufficient or the dielectric constant of the cured film may become high. From this viewpoint, a relatively high temperature is generally selected as the heating temperature. However, the composition according to the present invention can be cured at a relatively low temperature. Specifically, it is preferable to heat-cur at 350°C or lower, and to maintain a high residual film rate after curing, the curing temperature is more preferably 300°C or lower, and particularly preferably 250°C or lower. On the other hand, to promote the curing reaction and obtain a sufficiently cured film, the curing temperature is preferably 70°C or higher, and more preferably 100°C or higher. In the present invention, a low curing temperature of about 100°C is more preferable. The heating time is not particularly limited, but is usually 10 minutes to 24 hours, preferably 30 minutes to 3 hours. Furthermore, this heating time is the time from when the pattern film reaches the desired heating temperature. Typically, it takes several minutes to several hours for the pattern film to reach the desired temperature from its initial temperature. 【0125】 In another embodiment, the present invention further relates to a color conversion device (100) obtained from or resulting from the method of the present invention.

TEM analysis revealed that the cured ink had no voids and exhibited a smooth, non-aggregated layer structure. 【0195】 Example 13: Preparation of QD ink and fabrication of QD test cells The QD ink composition is prepared in the same manner as described in the examples, except that TiO2 particles are not used. Furthermore, QD test cells were prepared in the same manner as in Examples 5 and 6, except that the QD ink obtained in Example 13 was used, and the EQE was measured. The following table shows the measurement results. 【0196】 [Table 7] 【0197】 Example 14: Preparation of QD ink composition The QD ink composition is prepared using the following materials in the same manner as described above. 【0198】 [Table 8] 【0199】 Example 15: Preparation of bank composition The bank composition is prepared using the following materials. 【0200】 [Table 9] Sugar A: Sucrose ethylene oxide adduct Acrylic polymer B: A polymer (Natoco) having 2-propenoic acid, 2-methyl-, 2-hydroxyethyl 2-methyl-2-propenoate, 2-isocyanatoethyl 2-propenoate, and methyl 2-methyl-2-propenoate. Acrylic polymer A: An acrylic random polymer (Shin-Nakajima) made from a carbonic acid monomer and a monomer containing at least one aromatic ring group. 【0201】 Example 16: Device Fabrication The obtained bank composition was coated onto a bare glass substrate by spin coating, and the coated glass substrate was then pre-baked on a hot plate at 100°C for 90 seconds to an average film thickness of 13 μm. Exposure was performed using an i-line exposure machine, followed by cur-baking at 230°C for 30 minutes. Next, development was performed with 0.03% KOH for 60 seconds, and rinsing with deionized pure water for 30 seconds. As a result, a 12 μm bank (C / H) pattern was formed. Finally, Sample 1 was obtained. Next, sample 2 is prepared in the same manner as in "Preparation of Sample 1" above, except that the cure-bake conditions are changed from 230°C for 30 minutes to 100°C for 30 minutes. Then sample 2 is obtained. 【0202】 -OD calculation The transmittance of Sample 1 and Sample 2 at wavelengths of 400-700 nm was measured using a spectrophotometer CM-5 (Konica Minolta, Inc.) and converted to OD. 【0203】 -SEM analysis A cross-sectional SEM analysis was performed on sample 2. Figure 6 shows the results of the cross-sectional SEM analysis. An FT of 11.5 μm and a taper angle of 98° were observed. Cross-sectional SEM analysis reveals a clearly defined pixel structure. It also demonstrates the bank's excellent low-curing temperature (e.g., 100°C) characteristics. Furthermore, the bank composition develops well even with low-concentration alkaline developers. The process conditions and the obtained OD calculation results are shown in Table 3. Furthermore, SEM analysis confirmed that the patterns of Sample 1 and Sample 2 were formed without peeling (OK). 【0204】 [Table 10] 【0205】 -QD Ink Filing Test Next, the QD ink obtained in Example 14 was injected into Sample 1 and Sample 2 with a 12 mm gap, and then photocured by UV light irradiation. The obtained samples 1 and 2 are extremely clear. Cross-sectional SEM analysis revealed that the cured ink had no voids and exhibited a smooth layered structure without aggregation. Furthermore, both the compatibility between the bank and the curing ink, as well as the wettability and chemical stability with respect to the QD ink, are extremely good. Figure 7 shows the results of the SEM analysis. SEM analysis revealed no dissolution, detachment, or mixing of the bank structure with the QD ink.
