Description

Technical Field

[0001] The present invention relates to a coloring photosensitive resin composition, a color filter manufactured using the composition, and a display device including the color filter. Background Technology

[0002] Color filters are widely used in various display devices such as imaging equipment and liquid crystal displays (LCDs), and their application scope is rapidly expanding. Color filters used in imaging equipment, LCDs, etc., consist of three colors: red, green, and blue, or a pattern of three colors: yellow, magenta, and cyan.

[0003] The colored patterns of each color filter are typically formed using a coloring photosensitive resin composition containing colorants such as pigments or dyes, alkali-soluble resins, photopolymerizable compounds, photopolymerization initiators, and solvents. The coloring patterning process using the coloring photosensitive resin composition is usually carried out by photolithography.

[0004] Color filters are essential materials in liquid crystal display materials, organic light-emitting devices, and displays, requiring excellent reliability characteristics such as solvent resistance and adhesion. Furthermore, with the recent trend towards large-screen and high-definition displays, there is a need to develop technologies for color filters that improve color purity and chromaticity.

[0005] Korean Patent No. 10-2241229 discloses a composition for forming magenta pixels, which substantially does not contain colorants other than magenta. However, in the case of this composition, there is a problem that lightfastness cannot be adequately ensured and pattern tearing occurs.

[0017] The coloring photosensitive resin composition of the present invention can achieve the effects of ensuring sufficient lightfastness, not causing pattern tearing, and excellent color reproduction. Detailed Implementation

[0018] This invention relates to a coloring photosensitive resin composition, a color filter manufactured using the composition, and a display device including the color filter.

[0022] Coloring photosensitive resin composition

[0023] The components constituting the coloring photosensitive resin composition of the present invention will now be described in detail. However, the present invention is not limited to these components.

[0024] (A) Coloring agent

[0025] The colorant is characterized by including green pigments and magenta pigments.

[0029] In the green pigment of the present invention, from the perspective of color reproduction and lightfastness, it is preferable to contain 15 to 50 parts by weight of green pigment relative to 100 parts by weight of magenta pigment.

[0030] In addition to green pigment and magenta pigment, the colorant of the present invention may also contain other pigments, and in particular, from the viewpoint of pattern tearing, it is preferred to also contain yellow pigment.

[0031] (a1) Pigment

[0046] The pigment content can be 5 to 60% by weight, preferably 10 to 45% by weight, relative to the total weight of the solid components in the coloring photosensitive resin composition. When the pigment is within the above range, the color concentration of the pixels is sufficient even when a thin film is formed, and the light leakage of non-pixel areas will not deteriorate during development, thus preventing residue formation, which is therefore preferred.

[0047] As a pigment, a pigment dispersion in which the pigment particle size is uniformly dispersed is preferred. Examples of methods for uniformly dispersing pigment particles include methods involving dispersion treatment containing a pigment dispersant (a2), and pigment dispersions in which the pigment is uniformly dispersed in solution can be obtained according to the above methods.

[0048] (a2) Pigment dispersants

[0049] Pigment dispersants are added to depolymerize and maintain pigment stability. Commonly used pigment dispersants in the art can be used without restriction. Specific examples of pigment dispersants include surfactants based on cationic, anionic, nonionic, amphoteric, polyester, and polyamines, which can be used alone or in combination of two or more.

[0050] Specific examples of cationic surfactants include stearamine hydrochloride and amine or quaternary ammonium salts such as lauryltrimethylammonium chloride.

[0053] In addition, examples include polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, polyethylene glycol diesters, dehydrated sorbitan fatty acid esters, fatty acid modified polyesters, tertiary amine modified polyurethanes, and polyethyleneimine.

[0054] Furthermore, as a pigment dispersant, it is preferable to include acrylate dispersants such as butyl methacrylate (BMA) or N,N-dimethylaminoethyl methacrylate (DMAEMA) (hereinafter referred to as acrylate dispersants). Commercially available acrylate dispersants include DISPER BYK-2000, DISPER BYK-2001, DISPER BYK-2070, or DISPER BYK-2150. Acrylic dispersants can be used alone or in combination of two or more.

[0055] In addition to acrylate dispersants, other resin-based pigment dispersants can also be used as pigment dispersants. Other known resin-type pigment dispersants include, in particular, polyurethanes, polycarboxylic acid esters (represented by polyacrylates), unsaturated polyamides, polycarboxylic acids, polycarboxylic acid (partial) amine salts, ammonium salts of polycarboxylic acids, alkylamine salts of polycarboxylic acids, polysiloxanes, long-chain polyaminoamide phosphates, esters of hydroxyl-containing polycarboxylic acids and their modified products, or oily dispersants such as amides or their salts formed by the reaction of polyesters with free carboxyl groups with poly(lower alkylimides); water-soluble resins or water-soluble polymers such as (meth)acrylic acid-styrene copolymers, (meth)acrylic acid-(meth)acrylate copolymers, styrene-maleic acid copolymers, polyvinyl alcohol, or polyvinylpyrrolidone; polyester fibers; modified polyacrylates; ethylene oxide / propylene oxide adducts; and phosphate esters, etc.

[0056] Commercially available pigment dispersants of other resin types mentioned above include cationic resin dispersants, such as those from BYK Chemical Company under the trade names: DISPER BYK-160, DISPER BYK-161, DISPER BYK-162, DISPER BYK-163, DISPER BYK-164, DISPER BYK-166, DISPER BYK-171, DISPER BYK-182, etc. BYK-184; BASF's product names: EFKA-44, EFKA-46, EFKA-47, EFKA-48, EFKA-4010, EFKA-4050, EFKA-4055, EFKA-4020, EFKA-4015, EFKA-4060, EFKA-4300, EFKA-4330, EFKA-4400, EFKA-4406, EFKA-4510, EFKA-4800; Lubirzol's product names: SOLSPERS-24000, SOLSPERS-32550, NBZ-4204 / 10; Kawaken Fine Huax1's product names: HINOACT T-6000, HINOACT T-7000, HINOACT T-8000; AJINOMOTO's product names: AJISPUR PB-821, AJISPUR PB-822, AJISPUR PB-823; KYOEISHA Chemicals' trade names: FLORENE DOPA-17HF, FLORENE DOPA-15BHF, FLORENE DOPA-33, FLORENE DOPA-44, etc.

[0057] Besides acrylate dispersants, other resin-based pigment dispersants can be used alone or in combination of two or more, or in combination with acrylate dispersants.

[0058] The content of the pigment dispersant can be 5 to 60% by weight, preferably 15 to 50% by weight, relative to 100% by weight of the solids component of the pigment. When the pigment dispersant is within the above range, an appropriate viscosity level can be maintained to facilitate the preparation of coloring photosensitive resin compositions, and the gelation process becomes easier after pigment atomization and dispersion, which is therefore preferred.

[0059] (a3) dyes

[0060] Dyes can be used without restriction, as long as they are soluble in organic solvents. Preferably, dyes that are soluble in organic solvents and whose solubility, heat resistance, and solvent resistance in alkaline developers can be guaranteed are preferred.

Preferably, the dye can be a compound classified as a dye in a color index (published by the Association of Colorists and Toners) or a well-known dye (color dye) described in dyeing instructions.

[0062] In specific examples of dyes, the preferred choice as a CI solvent dye is:

[0078] CI Direct Green coloring dyes include 25, 27, 31, 32, 34, 37, 63, 65, 66, 67, 68, 69, 72, 77, 79, and 82.

[0079] Furthermore, the preferred mordant dyes for CI dyeing are:

[0080] CI mordant yellow includes yellow dyes such as 5, 8, 10, 16, 20, 26, 30, 31, 33, 42, 43, 45, 56, 61, 62, and 65.

[0081] CI mordant orange dyes include 3, 4, 5, 8, 12, 13, 14, 20, 21, 23, 24, 28, 29, 32, 34, 35, 36, 37, 42, 43, 47, and 48.

[0084] Each of the above dyes can be used alone or in combination of two or more.

[0085] When the aforementioned colorant also contains the aforementioned dye, the dye content can be 0.5 to 80% by weight, preferably 0.5 to 60% by weight, and more preferably 1 to 50% by weight, relative to 100% by weight of the solid component of the colorant. When the dye is contained within the aforementioned content range, the problem of reduced reliability due to dye leaching from organic solvents after pattern formation can be prevented, and sensitivity is improved, therefore it is preferred.

[0086] The content of the colorant can be 1 to 20% by weight relative to the total weight of the solid components in the coloring photosensitive resin composition, preferably 1 to 10% by weight. When the colorant is within the above range, it is preferable that the color concentration of the pixels is sufficient when forming the film, and that the light leakage of non-pixel areas does not deteriorate during development, thereby preventing the formation of residues.

[0087] In this invention, the total weight of the solid components in the coloring photosensitive resin composition refers to the total weight of the remaining components of the coloring photosensitive resin composition excluding the solvent.

[0088] (B) Alkali-soluble resin

[0089] The alkali-soluble resin is characterized by being copolymerized with an olefinically unsaturated monomer (b1) having a carboxyl group as an essential component in order to be soluble in the alkaline developing solution used in the developing process during pattern formation.

[0090] The content of alkali-soluble resin can be 10 to 80% by weight, preferably 10 to 70% by weight, relative to the total weight of the solid components in the coloring photosensitive resin composition. When the alkali-soluble resin is included in the above range, pattern formation is easy due to its sufficient solubility in the developer, and the reduction of film in the pixel portion of the exposed area is prevented during development, thereby improving the light leakage of the non-pixel portion, which is therefore preferred.

[0091] The acid value of the alkali-soluble resin is preferably between 30 mg·KOH / g and 150 mg·KOH / g, which improves the compatibility with dyes and the long-term stability of the photosensitive resin composition. When the acid value of the alkali-soluble resin is less than 30 mg·KOH / g, it is difficult for the photosensitive resin composition to ensure a sufficient development rate. When it exceeds 150 mg·KOH / g, the adhesion to the substrate decreases, the pattern is prone to short-circuiting, and the compatibility with dyes becomes problematic. This leads to dye precipitation in the photosensitive resin composition or a decrease in the long-term stability of the photosensitive resin composition, thereby increasing the viscosity.

[0092] Hydroxyl groups can be added to ensure additional developability of alkali-soluble resins. Adding hydroxyl groups to alkali-soluble resins has the effect of increasing development speed.

[0093] The sum of the hydroxyl values ​​of the alkali-soluble resin and the photopolymerizable compound (described later) is preferably between 50 mg·KOH / g and 250 mg·KOH / g. When the sum of the hydroxyl values ​​of the alkali-soluble resin and the photopolymerizable compound is less than 50 mg·KOH / g, sufficient development speed cannot be ensured. When it exceeds 250 mg·KOH / g, the dimensional stability of the formed pattern decreases, thus the straightness of the pattern is easily wiped away, and the compatibility with the dye decreases, resulting in long-term stability problems.

[0094] (b1) Alkenyl unsaturated monomers with carboxyl groups

[0095] Specific examples of olefinic unsaturated monomers having carboxyl groups include monocarboxylic acids such as acrylic acid, methacrylic acid, and crotonic acid; dicarboxylic acids such as fumaric acid, medaconic acid, and itaconic acid; and anhydrides of these dicarboxylic acids; and polymers such as ω-carboxylated polycaprolactone mono(meth)acrylates having carboxyl and hydroxyl groups at both ends, preferably acrylic acid and methacrylic acid.

[0096] The aforementioned alkali-soluble resin can be manufactured by copolymerizing the aforementioned carboxyl-containing vinyl unsaturated monomer with a hydroxyl-containing vinyl unsaturated monomer (b2). Alternatively, the aforementioned alkali-soluble resin can be prepared by copolymerizing a carboxyl-containing olefinic unsaturated monomer with a glycidyl group (b3). Alternatively, the aforementioned alkali-soluble resin can be manufactured by copolymerizing a carboxyl-containing olefinic unsaturated monomer, a hydroxyl-containing olefinic unsaturated monomer, and a glycidyl group compound.

[0097] (b2) Alkenyl unsaturated monomers with hydroxyl groups

[0098] Specific examples of olefinic unsaturated monomers having hydroxyl groups include: 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, 4-hydroxybutyl (meth)acrylate, 2-hydroxy-3-phenoxypropyl (meth)acrylate, N-preferably hydroxyethylacrylamide, etc., preferably 2-hydroxyethyl (meth)acrylate, and two or more may be used in combination.

[0099] (b3) Compounds containing glycidyl groups

[0154] Color filters and display devices

[0155] Furthermore, the present invention provides a color filter comprising a colored pattern made of a coloring photosensitive resin composition according to the present invention, and a display device comprising the color filter.

[0156] Display devices that can include such color filters may include, but are not limited to, liquid crystal display devices, OLEDs, flexible display devices, etc., and may include all display devices known in the applicable field.

[0157] The color filter can be manufactured by coating a substrate with the coloring photosensitive resin composition of the present invention described above, followed by photocuring and development to form a pattern.

[0158] First, after coating a coloring photosensitive resin composition onto a substrate, volatile components such as solvents are removed by heating and drying to obtain a smooth coating film.

[0159] As a coating method, methods such as spin coating, cast coating, roller coating, slot spin coating, or slot coating can be used. After coating, the coating is subjected to heat drying (pre-baking) or reduced pressure drying, where heating causes volatile components such as solvents to evaporate. Here, the heating temperature is typically 70 to 200°C, preferably 80 to 130°C. The thickness of the coating after heat drying is typically about 1 to 8 μm. The coating thus obtained is then irradiated with ultraviolet light through a mask used to form the target pattern. At this time, it is preferable to use a device such as a mask aligner or a stepper to ensure that parallel light rays are uniformly irradiated throughout the exposure area and to ensure precise alignment of the mask and the substrate. When irradiated with ultraviolet light, the ultraviolet-irradiated portion cures.

[0160] As the ultraviolet light source, g-line (wavelength: 436nm), h-line, i-line (wavelength: 365nm), etc., can be used. The amount of ultraviolet light irradiation can be appropriately selected as needed, and the present invention is not limited thereto. When the cured coating comes into contact with a developer to dissolve the unexposed areas and develop, the target pattern shape can be formed.

[0161] As a developing method, any of the following can be used: liquid addition method, immersion method, spray method, etc. Furthermore, the substrate can be tilted at any angle during development. The developing solution is typically an aqueous solution containing an alkaline compound and a surfactant. The aforementioned alkaline compound can be either an inorganic alkaline compound or an organic alkaline compound. Specific examples of inorganic alkaline compounds include sodium hydroxide, potassium hydroxide, disodium hydrogen phosphate, sodium dihydrogen phosphate, diammonium hydrogen phosphate, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, sodium silicate, potassium silicate, sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, sodium borate, potassium borate, ammonia, etc. Specific examples of organic alkaline compounds include tetramethylammonium hydroxide, 2-hydroxyethyltrimethylammonium hydroxide, monomethylamine, dimethylamine, trimethylamine, monoethylamine, diethylamine, triethylamine, monoisopropylamine, diisopropylamine, ethanolamine, etc.

[0162] These inorganic and organic basic compounds can be used alone or in combination of two or more. The concentration of the basic compound in the alkaline developer is preferably 0.01 to 10% by mass, more preferably 0.03 to 5% by mass.

[0163] The surfactant in an alkaline developer can be at least one selected from the group consisting of nonionic surfactants, anionic surfactants, and cationic surfactants.

[0164] Specific examples of nonionic surfactants include polyoxyethylene alkyl ethers, polyoxyethylene aryl ethers, polyoxyethylene alkylaryl ethers, other polyoxyethylene derivatives, oxyethylene / oxypropylene block copolymers, sorbitan fatty acid esters, polyoxyethylene sorbitol fatty acid esters, polyoxyethylene sorbitol fatty acid esters, glycerol fatty acid esters, polyoxyethylene fatty acid esters, polyoxyethylene alkylamines, etc.

[0165] Specific examples of anionic surfactants include: higher alcohol sulfates such as sodium lauryl sulfate and sodium oleyl sulfate; alkyl sulfates such as sodium lauryl sulfate and ammonium lauryl sulfate; and alkyl aryl sulfonates such as sodium dodecylbenzene sulfonate and sodium dodecylnaphthalene sulfonate.

[0166] Specific examples of cationic surfactants include amine salts such as stearamine hydrochloride and lauryltrimethylammonium chloride, or quaternary ammonium salts. These surfactants can be used alone or in combination of two or more.

[0167] The concentration of surfactant in the developer is typically 0.01 to 10% by mass, preferably 0.05 to 8% by mass, and more preferably 0.1 to 5% by mass. After development, the product is washed with water, or, if necessary, baked at 150 to 230°C for 10 to 60 minutes.

[0168] The invention will be described in more detail below based on embodiments, but the embodiments disclosed below are merely exemplary, and the scope of the invention is not limited to these embodiments. The scope of the invention is defined by the claims, and includes all modifications within the meaning and scope equivalent to those stated in the claims.
