Description

Photosensitive coloring resin composition, color filter and its manufacturing method, and liquid crystal display device This invention relates to a photosensitive coloring resin composition, and more particularly to a high-precision photosensitive coloring resin composition with excellent time-dependent filtration stability, a color filter, a method for manufacturing the same, and a liquid crystal display device. Currently, color filters are widely used in color LCD displays, color fax machines, color cameras, and other applications. As the market demand for color LCD displays continues to expand, the manufacturing technology for color filters is becoming increasingly diversified, including methods such as dyeing, printing, electroplating, and dispersion, with dispersion being the most mainstream. The dispersion process involves first dispersing the colorant in a photosensitive resin to form a photosensitive coloring resin composition, then coating the photosensitive coloring resin composition onto a glass substrate. After exposure and development, a specific pattern is obtained. Repeating the coating, exposure, and development process three times yields the pixel coloring patterns (hereinafter referred to as "pixel layers" or "patterns") for the red (R), green (G), and blue (B) colors in the color filter. Generally, to further improve the contrast of the color filter, a black matrix (or light-blocking layer) is placed between the pixel coloring patterns. The required quality items for photosensitive coloring resin compositions for color filters include contrast and brightness, but in recent years, the importance of quality items such as filtration efficiency and the presence of crystalline foreign matter has also increased. In the manufacturing of photosensitive coloring resin compositions for color filters, a filtration step is the final step; however, if large particles remain, the filter screen must be replaced frequently, significantly reducing the filtration speed. Furthermore, there is a problem of crystalline foreign matter being generated during the post-baking step in the color filter manufacturing process. Furthermore, in recent years, with the miniaturization of pixels in liquid crystal display devices, the pore size of filter screens has become smaller in order to remove even finer foreign objects. Therefore, a very high level of filtration performance is required. At the same time, it is also necessary to avoid the problem of deterioration in filtration stability after long-term storage. Therefore, how to improve the high precision and long-term filtration stability of photosensitive coloring resin compositions is a problem that technicians in this field urgently need to solve. In view of this, the object of the present invention is to provide a photosensitive coloring resin composition with high precision and excellent time-dependent filtration stability, a color filter using the photosensitive coloring resin composition, a method for manufacturing the same, and a liquid crystal display device.

The various components of the photosensitive coloring resin composition used in this invention will be described in detail below. In the following text, "solid components of the photosensitive coloring resin composition" refers to the components other than the solvent (F); "total weight of the solid components of the photosensitive coloring resin composition" refers to the total weight of the components other than the solvent (F).

[ Colorant ( A ) Colorant (A) includes colorant (A-1). In addition, colorant (A) may also include coloring agents other than colorant (A-1) (A-2) and other colorants (A-3). Colorant ( A-1 The colorant (A-1) has the structure shown in the following formula (a1-1): In equation (a1-1), A 1 ~A 16 Each of these independently represents a hydrogen atom, a halogen atom, a hydroxyl group, or the structure shown in formula (a1-2) below, A 1 ~A 16 At least one of them is a halogen atom, A 1 ~A 16 At least one of them is the structure shown in equation (a1-2), and A 1 ~A 16 At least one of them is a hydroxyl group. In equation (a1-2), X represents a divalent linking basis, and A... 17 * indicates a substituted or unsubstituted phenyl group, and * indicates the bond position. As A 1 ~A 16 The halogen atoms represented can be chlorine atoms and fluorine atoms. Examples of divalent linking groups represented by X include: oxygen atoms, sulfur atoms, or -N(R) atoms. a1 )-base. R a1 It represents a hydrogen atom or an aliphatic hydrocarbon group with 1 to 6 carbon atoms. From the viewpoint that the skirt-shaped bottom of the short-wavelength side where the absorption becomes the main absorption is greatly reduced and a sharp rise is observed, it is preferred to be an oxygen atom or a sulfur atom, and more preferably an oxygen atom. As a result of A 17The substituents of the phenyl group are not particularly limited, and examples include: halogen atoms, alkyl groups, alkoxy groups, alkoxycarbonyl groups, aryl groups, aryloxy groups, aryloxycarbonyl groups, cyano groups, etc. The alkyl or aryl groups in the above substituents may be further substituted by the above substituents, or they may be unsubstituted. For example, the alkyl or aryl groups in the above substituents may be substituted by halogen atoms, alkyl groups, alkoxy groups, alkoxycarbonyl groups, aryl groups, aryloxy groups, aryloxycarbonyl groups, or cyano groups. Furthermore, the alkyl group may be cleaved by oxygen atoms, sulfur atoms, nitrogen atoms, etc., or it may remain cleaved. From the viewpoint of selective light transmittance or solubility in solvents, the above substituents are preferably alkoxycarbonyl groups, alkyl groups substituted with alkoxycarbonyl groups, and even more preferably alkoxycarbonyl groups. Furthermore, the alkyl group in the aforementioned substituents can be linear, branched, cyclic, or a combination thereof, with linear or branched being preferred. From the viewpoint of ease of synthesis and solubility in alkali-soluble resins and solvents, linear is more preferred. The number of carbon atoms in the alkyl group is not particularly limited, but is generally 1 or more, preferably 2 or more. More preferably 6 or less, even more preferably 5 or less, further preferably 4 or less, and especially preferably 3 or less. By setting the value to the lower limit or above, there is a tendency to increase solubility in solvents; and by setting the value to the upper limit or below, there is a tendency to generate hydrophobic interactions with the hydrophobic portion of the alkali-soluble resin, thereby suppressing intermolecular aggregation during the heating step. Specific examples of alkyl groups include methyl, ethyl, propyl, n-butyl, isobutyl, pentyl, and hexyl. From the viewpoint of maintaining solubility in a solvent and efficiently generating hydrophobic interactions with the hydrophobic portion of an alkali-soluble resin, ethyl, propyl, n-butyl, or isobutyl are preferred, more preferably ethyl or propyl, and even more preferably ethyl. Furthermore, the aryl group in the aforementioned substituents can be an aromatic hydrocarbon cyclic group or an aromatic heterocyclic group. The number of carbon atoms in the aryl group is not particularly limited, but is generally 4 or more, preferably 6 or more. More preferably, it is 12 or less, even more preferably 10 or less, and further preferably 8 or less. By setting it to the aforementioned lower limit or above, the availability of raw materials tends to become easier; and by setting it to the aforementioned upper limit or below, the solubility in solvents tends to increase. Aromatic hydrocarbon rings, as aromatic hydrocarbon cyclic groups, can be monocyclic or condensed rings. Examples of aromatic hydrocarbon cyclic groups include: benzene rings, naphthalene rings, cyclopentadiene rings, indene rings, azurite rings, and heptadene rings, which have one free valence atom. Furthermore, the aromatic heterocyclic group can be a monocyclic ring or a condensed ring. Examples of aromatic heterocyclic groups include: furan rings, thiophene rings, pyrrole rings, 2H-pyran rings, 4H-thiaran rings, pyridine rings, 1,3-carbazolium rings, isocarbazolium rings, 1,3-thiazole rings, isothiazole rings, imidazole rings, pyrazole rings, furazolidone rings, pyrazine rings, pyrimidine rings, pyrazine rings, 1,3,5-triazine rings, benzofuran rings, and 2-benzofuran rings. The rings include uranium ring, benzothiophene ring, 2-benzothiophene ring, 1H-pyrrolidine ring, indole ring, isoindole ring, indoleazine ring, 2H-1-benzopyran ring, 1H-2-benzopyran ring, quinoline ring, isoquinoline ring, 4H-quinazine ring, benzimidazole ring, 1H-indazole ring, quinoline ring, quinoline ring, quinoline ring, phthalazine ring, 1,8-naphthidine ring, purine ring, pteridine ring, etc. When the benzene ring in formula (a1-2) has any substituents, the number of substitutions is not particularly limited, but is preferably 4 or less, more preferably 3 or less, further preferably 2 or less, and especially preferably 1. By setting it to the above upper limit value or below, there is a tendency to promote the association formation of phthalocyanines and sharpen the absorption on the short wavelength side of the main absorption. Furthermore, when the benzene ring in formula (a1-2) has any substituents, there is no particular limitation on the substitution position. Positions 2, 3, and 4 can be listed. From the perspective of the ease of association formation of phthalocyanines, position 4 is preferred. Furthermore, in the multiple structures shown by formulas (a1-2) present in a molecule, the benzene ring may have any substituents that are the same or different. In the zinc phthalocyanine dyes shown in formula (a1-1), A 1 ~A 16 Each atom, chlorine atom, fluorine atom, or the structure shown in formula (a1-2) above can be represented independently, preferably A. 1 ~A 16One or more of the components have the structure shown in formula (a1-2) above, more preferably two or more have the structure shown in formula (a1-2) above, even more preferably four or more have the structure shown in formula (a1-2) above, and particularly preferably six or more have the structure shown in formula (a1-2) above. Furthermore, it is more preferably 15 or fewer have the structure shown in formula (a1-2) above, more preferably 14 or fewer have the structure shown in formula (a1-2) above, even more preferably 12 or fewer have the structure shown in formula (a1-2) above, and particularly preferably 10 or fewer have the structure shown in formula (a1-2) above. By setting it to the lower limit or above, there is a tendency to increase solubility in organic solvents. Furthermore, by setting it to the upper limit or below, there is a tendency to maintain solubility in organic solvents and to efficiently generate hydrophobic interactions with the hydrophobic portion of the alkali-soluble resin. For example, A 1 ~A 16 In the above formula (a1-2), the structure is preferably 1 to 15, more preferably 2 to 14, even more preferably 4 to 12, and most preferably 6 to 10. In the zinc phthalocyanine dyes shown in formula (a1-1), A 1 ~A 16 Each atom, chlorine atom, fluorine atom, or the structure shown in formula (a1-2) above can be represented independently, preferably A. 1 ~A 16 One or more of the atoms are chlorine or fluorine atoms, more preferably two or more, even more preferably four or more, and most preferably six or more. It is also preferable to have 15 or fewer chlorine or fluorine atoms, more preferably 14 or fewer, even more preferably 12 or fewer, and most preferably 10 or fewer. By setting the value to the lower limit or above, there is a tendency to maintain solubility in organic solvents and to efficiently generate hydrophobic interactions with the hydrophobic portion of the alkali-soluble resin. Furthermore, by setting the value to the upper limit or below, there is a tendency to increase solubility in organic solvents. For example, A 1 ~A 16 In this mixture, the number of chlorine or fluorine atoms is preferably 1 to 15, more preferably 2 to 14, even more preferably 4 to 12, and most preferably 6 to 10. When the photosensitive coloring resin composition does not contain a colorant (A-1), it is prone to having low stability after high-fineness filtration. Although the detailed mechanism of this effect is not yet clear, the following factors are speculated. Generally, phthalocyanine colorants have a planar structure, and their molecules easily precipitate and form aggregates through π-π stacking interactions. Although phthalocyanine colorants with substituents can improve solubility and prevent precipitation, their chemical structure still exhibits high symmetry, making them prone to gradually stacking and forming fine foreign matter after long-term storage. This makes it difficult to meet the requirements of the miniaturization of pixels in recent liquid crystal display devices for long-term filtration stability. In contrast, colorant (A-1), through its hydroxyl structure, forms hydrogen bonds with the alkali-soluble resin (B) while maintaining good optical properties. This makes colorant (A-1) less prone to stacking even after long-term storage, effectively improving the problem of low long-term filtration stability for high-resolution displays. Furthermore, when A 1 ~A 16 When more than 6 of the atoms in the photosensitive coloring resin are fluorine atoms, the composition exhibits higher fineness and stability after filtration. Additionally, when A 17 When 4-alkoxycarbonylphenyl is represented, the photosensitive coloring resin composition exhibits higher fineness and stability after filtration. Specific examples of colorants (A-1) include the following compounds. Equation (a1-3) Equation (a1-4) Equation (a1-5) Equation (a1-6) Equation (a1-7) Equation (a1-8) Equation (a1-9) Equation (a1-10) Equation (a1-11) In formulas (a1-3) to (a1-9), (a1-11), and (a1-12), Me represents methyl, Et represents ethyl, n-Pr represents n-propyl, and i-Bu represents isobutyl. Based on the total weight of the solid components of the photosensitive coloring resin composition, the content of colorant (A-1) is typically from 0.5% to 80% by weight, preferably from 1% to 70% by weight, and even more preferably from 5% to 50% by weight. Colorant ( A-2 The colorant (A-2) has the structure shown in the following formula (a2-1): In equation (a2-1), A 21 ~A 28 Each can be independently represented by a hydrogen atom or a halogen atom, A 31 ~A 38 Each can independently represent the structure shown in equation (a2-2) below. In equation (a2-2), X' represents a divalent linking basis, and A 39 * indicates a substituted or unsubstituted phenyl group, and * indicates the bond position. A 21 ~A 28 Each atom can be independently represented as a hydrogen atom, chlorine atom, or fluorine atom. From the viewpoint of solubility in solvents, chlorine or fluorine atoms are preferred, and fluorine atoms are even more preferred. Also, A... 21 ~A 28 They can be the same or different; from the perspective of the ease of association formation of phthalocyanines, the same is preferable. For example, the A contained in the above formula (a2-1) can be listed. 21 ~A 28 All atoms are in the state of fluorine atoms, and the A atoms contained in the above formula (a2-1) 21 ~A 28 It consists entirely of chlorine atoms. As a binary linking basis represented by X', we can list the binary linking bases listed as X in the above equation (a1-2). The benzene rings in formula (a2-2) (the eight benzene rings bonded to the phthalocyanine ring via X') can have any substituents. As a result of A 39 The substituent for the phenyl group can be A, as shown in the above formula (a1-2). 17 The substituents of the phenyl group are listed below. When the benzene ring in formula (a2-2) has any substituents, the number of substitutions is not particularly limited. Preferably, it is 4 or less, more preferably 3 or less, further preferably 2 or less, and especially preferably 1. By setting it to the above upper limit value or below, there is a tendency to promote the association formation of phthalocyanines and sharpen the absorption on the short wavelength side of the main absorption. Furthermore, when the benzene ring in formula (a2-2) has substituents, there is no particular limitation on the substitution position. Positions 2, 3, and 4 can be listed. From the perspective of the ease of association formation of phthalocyanines, position 4 is preferred. Specific examples of colorants (A-2) include the following compounds. Equation (a2-3) Equation (a2-4) Equation (a2-5) Equation (a2-6) Equation (a2-7) Equation (a2-8) Equation (a2-9) Equation (a2-10) Equation (a2-11) In formulas (a2-12), (a2-3) to (a2-6), and (a2-12), Me represents methyl, Et represents ethyl, n-Pr represents n-propyl, and i-Bu represents isobutyl. When the photosensitive coloring resin composition contains colorant (A-2), the photosensitive coloring resin composition has higher fineness and time-filtration stability. Based on the total weight of the solid components of the photosensitive coloring resin composition, the content of colorant (A-2) is typically from 0.5% to 75% by weight, preferably from 1% to 70% by weight, and even more preferably from 5% to 50% by weight.

Methods for uniformly dispersing / mixing the components include using a mixer and / or a disperser for mixing and / or dispersion. Dispersers include roller mills such as two-roll mills and three-roll mills, ball mills, vibratory ball mills, paint conditioners, continuous disc bead mills, and continuous ring bead mills. For dispersion conditions in bead mills, the bead diameter used is preferably 0.03 mm to 2.00 mm, more preferably 0.10 mm to 1.0 mm. < Manufacturing method of color filters >The method for manufacturing the color filter of the present invention includes forming a pixel layer using a photosensitive coloring resin composition as described above. Specifically, the aforementioned photosensitive coloring resin composition, mixed in a solution state, is coated onto a substrate using coating methods such as rotary coating, cast coating, inkjet coating, or roller coating. After coating, most of the solvent is removed by vacuum drying, and then the solvent is removed by pre-bake to form a pre-baked coating film. The conditions for vacuum drying and pre-baking vary depending on the type and ratio of each component. Generally, vacuum drying is performed at a pressure of 0 to 200 mmHg for 1 to 60 seconds, and pre-baking is performed at a temperature of 70 to 110°C for 1 to 15 minutes. After pre-baking, the pre-baked coating film is exposed to a specified mask and developed by immersing it in a developing solution at a temperature of 23±2°C for 15 seconds to 5 minutes to remove unwanted portions and form a pattern (pixel layer). The light used for exposure is preferably ultraviolet light such as g-rays, h-rays, and i-rays, and the ultraviolet light device can be a (ultra) high-pressure mercury lamp or a metal halide lamp. Specific examples of the aforementioned substrates include: alkali-free glass, soda-lime glass, hard glass (Pyles glass), quartz glass, sodium glass, or substrates with a transparent conductive film attached to such glass for liquid crystal display devices; or substrates for photoelectric conversion devices such as solid-state imaging devices (e.g., silicon substrates). These substrates generally first form a black matrix that isolates each pixel layer. Furthermore, the developer is specifically an alkaline aqueous solution composed of at least one of the following alkaline compounds: sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, sodium silicate, sodium methyl silicate, ammonia, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, choline, pyrrole, guanidine, 1,8-diazabicyclo[5.4.0]-7-undecene, with a concentration generally from 0.001% to 10% by weight, preferably from 0.005% to 5% by weight, and even more preferably from 0.01% to 1% by weight. When using the developer solution made from the aforementioned alkaline aqueous solution, it is generally washed with water after development, and then the pattern is dried with compressed air or compressed nitrogen. After air drying, the substrate with the photocurable coating layer is heated at 100–280°C for 1–15 minutes using a heating device such as a hot plate or oven to remove volatile components from the coating and to allow unreacted vinyl unsaturated double bonds in the coating to undergo a thermocuring reaction. The same steps are repeated three times on predetermined pixels using photosensitive coloring resin compositions of various colors (mainly red, green, and blue) to obtain red, green, and blue pixel layers. Secondly, an ITO (indium tin oxide) vapor-deposited film is formed on the pixel layer under vacuum at a temperature of 220-250°C. If necessary, the ITO vapor-deposited film is etched and wired, and then polyimide for liquid crystal alignment is coated. After heat treatment, it can be used as a color filter for liquid crystal displays. Furthermore, the aforementioned liquid crystal alignment film is used to restrict the alignment of liquid crystal molecules. It is not specifically limited here; any inorganic or organic material can be used. The technology for forming the liquid crystal alignment film is well known to those skilled in the art and is not the focus of this invention, therefore it will not be described further. < LCD display device The liquid crystal display device of the present invention includes a color filter substrate containing a color filter manufactured using the color filter manufacturing method described above; and a driving substrate on which a thin film transistor (TFT) is provided. In this embodiment, the liquid crystal display device is configured with two substrates facing each other, with a gap (cell gap) inserted between them. The periphery of the two substrates is bonded together with a sealant. Liquid crystal is injected into the substrate surface and the gap defined by the sealant, sealing the injection hole to form a liquid crystal cell. Then, a polarizing plate is bonded to the outer surface of the liquid crystal cell, i.e., to the other side surfaces of each substrate constituting the liquid crystal cell, to obtain the liquid crystal display device. As for the liquid crystals used above, that is, liquid crystal compounds or liquid crystal compositions, there are no particular limitations here, but any kind of liquid crystal compound and liquid crystal composition may be used. The present invention will be further described with reference to the following embodiments, but it should be understood that these embodiments are for illustrative purposes only and should not be construed as limiting the implementation of the present invention. < Example > [ Colorant ( A-1 Synthesis example The following is an example of the synthesis of colorant (A-1): Synthesis Example A1-1: 3.96 g (20 mmol) of 3,4,6-trifluoro-5-hydroxy-1,2-phenylenedionitrile, 1.45 g (2.5 mmol) of potassium fluoride, and 10 mL of acetone were mixed.

Then, the filtration ratio (F) of the photosensitive coloring resin compositions of the Examples and Comparative Examples was calculated using the following formula (1): F = f2 / f1 × 100% Formula (1) Finally, the high-precision filtration stability of the photosensitive coloring resin compositions over time was evaluated according to the following criteria. ◎: F≥99% ○: 97%≤F<99% △: 95%≤F<97% ×: F<95% < Evaluation results As shown in Table 1, compared with the photosensitive resin composition (Examples 1-10) that includes a specific colorant (A-1), the photosensitive resin compositions of Comparative Examples 1 and 2 that do not include colorant (A-1) have poor high fineness and time-filtration stability evaluation. Furthermore, when the halogen atom in the colorant (A-1) is a fluorine atom (Examples 1-4, 6-9), the high precision of the photosensitive resin composition is better after time-filtration stability evaluation. Furthermore, when the colorant (A-1) contains 4-alkoxycarbonylphenyl (Examples 1-4, 6-9), the high fineness of the photosensitive resin composition is also better after time-filtration stability evaluation. Furthermore, when the photosensitive resin composition further includes a colorant (A-2) (Examples 1, 2, 6, 7), the high fineness and time-filtration stability of the photosensitive resin composition are further improved. In summary, the photosensitive resin composition of the present invention includes a specific colorant (A-1), thus enabling the acquisition of a photosensitive coloring resin composition with high precision and excellent stability after filtration over time. Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
