EMBODIMENT OF THE INVENTION [Technical Field] The present invention relates to the formation of a coating film by a coating device corresponding to a liquid-repellent coating such as a slit coating, and is used for the production of a color filter for a liquid crystal display or the like. A light-shielding resin composition for a color filter, and a color filter formed using the same. [Prior Art] In the prior art, the "color filter" is widely used for the purpose of colorization of liquid crystal displays, and usually, the three primary color pixel configurations of red, green, and blue are used in a mosaic form. In order to ensure the contrast of the displayed images, a method of forming a light-blocking lattice (hereinafter referred to as an ink matrix) between the three primary color pixels of red, green, and blue is obtained. As a method of producing the black matrix of the color filter, there are known a pigment dispersion method and a vapor deposition method, and a light-shielding resin composition in which a pigment is dispersed in a photosensitive resin composition (hereinafter also referred to as shading) The use of a photoresist or a black photoresist ink, a pigment dispersion method for producing a black matrix by lithography, is widely practiced. The reason for this is that fine images can be formed accurately and precisely by the lithography, and the pigment used as the light-shielding material has excellent light resistance, heat resistance and solvent resistance. As the black photoresist ink of the pigment dispersion method, it generally contains a pigment, a photosensitive resin, a photopolymerization initiator, and a solvent. The solvent acts as a solvent for dissolving the photosensitive resin and the photopolymerization initiator, and also serves as a main component of the function of the dispersion medium for dispersing the pigment. Further, since the solvent is applied to the black resist ink to a large extent (viscoelasticity, ductility, wettability, -5-200903047 smoothness, drying property, etc.) and storage stability, it is selected as a very important one. . Therefore, various solvents have been discussed so far and used. For example, as a solvent suitable for a color photoresist ink, it is disclosed in Patent Document i that there are ethers, esters, and carbonyls. Specific examples include ethers such as propylene glycol monomethyl ether acetate, cyclohexanone in carbonyls, and ethyl 3-ethoxypropionate in esters, which are disclosed by the combination of such solvents. Corresponds to the flatness in the liquid-saving coating device. However, in the combination of these solvents, it is expected to satisfy the dispersibility of the black pigment having a solid content of 45% or more, and the solubility of the acrylic photosensitive resin having a solid content of 8% or more and a large amount of the photopolymerization initiator. Among the high light-shielding photoresist inks, there are problems in that solubility, pigment dispersibility, and storage stability are insufficient. In addition, as a solvent which can be used in Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5, various ethers, esters, ketones, and alcohols are described, and only solvents having a higher boiling point are used. The solubility of the black pigment having a solid content of 45% or more is satisfied, and the solubility of the acrylic photosensitive resin having a solid content of 8% or more and a large amount of the photopolymerization initiator is not described. It is required to satisfy the dispersibility of a black pigment having a solid content of 45% or more, and a high light-shielding photoresist for the solubility of an acrylic photosensitive resin having a solid content of 8% or more and a large amount of a photopolymerization initiator. Solubility, pigment dispersibility, storage stability, therefore, the essential cyclohexanone is not easily replaced by other components, the design is limited, and it is suitable for the design of the corresponding liquid-saving coating device. -6- 200903047 In addition, as an additive to black photoresist inks, surfactants are widely used. An interfacial activator and a fluorine-based surfactant are disclosed in Patent Document 1. Surfactants have a great influence on the coating properties of black photoresist inks. Therefore, the selection of surfactants is extremely important, similar to the choice of solvents. It is discussed that the solvent and surfactant can be optimally combined. Coating properties. As a subject to apply a photoresist ink to a substrate in a coating apparatus corresponding to a liquid-saving apparatus, it is required that the indenter of the discharge portion is not easily dried, and the coating film is dry and has no sticky feeling. Therefore, the drying speed of the photoresist ink must be within an appropriate range.

Further, the present invention is a color filter having a film of the resin composition for a color filter. Hereinafter, the present invention will be described in detail. The light-shielding resin composition for a color filter of the present invention (hereinafter, the stomach M-light resin composition) is a solvent containing 80 to 90% by weight of a solvent, preferably a solid solvent containing 10 to 20% by weight of a solvent to be removed. should. Its φ, go -8- 200903047 The solid content of the solvent is defined as the liquid remaining in the residual component after hardening, containing a monomer or a liquid surfactant. The viscosity of the light-shielding resin composition for a color filter of the present invention at a normal temperature (25 ° C) is 1.0 to 10. OmPa.s, preferably 2.0 to 7.0 rnPa*s, more preferably 3.0 to 6.OmPa.s. When the viscosity is not in the above range, 'the viscosity is too high, or too low, not only is not easy to apply a certain film thickness', and defects such as lines, spots, cracks, rebounds, etc. are easily generated on the coated surface, and the desired one cannot be obtained. Coating properties. The viscosity is measured by a commercially available viscometer, and a rotary viscometer such as a B-type viscometer or an E-type viscometer is preferred. The light-shielding resin composition for a color filter of the present invention contains 80 to 90% by weight of a solvent, and more preferably has a viscosity of the above range, and the solvent is contained in an amount of 82 to 86% by weight. The light-shielding resin composition for a color filter of the present invention contains a first solvent, a second solvent, and a third solvent as a solvent as essential components. The first solvent is a solvent having one ethoxycarbonyl group (CH3COO-) in the molecule. The first solvent is preferably a solvent having a propylene glycol skeleton represented by -〇CH2CH(CH3)0-. Wherein, the oxygen atom of the propylene glycol skeleton can be used as a part of the ester bond of the ethyl ethoxy group, or can be formed by condensation of a mutual propylene glycol skeleton, condensation with another alcohol to form an ether bond, or the like, or bonding with a hydrogen atom. It is also possible to form a terminal hydroxyl group. The first solvent should have a boiling point of from 1 40 ° C to 1 80 ° C at normal pressure. Examples of the first solvent are: alkyl acetate, aryl acetate, aralkyl acetate, ethylene glycol monoalkyl ether acetate, diethylene glycol monoalkyl ether ethyl-9-200903047 Examples of acetates of monovalent alcohols such as acid esters, propylene glycol monoalkyl ether acetates, dipropylene glycol monoalkyl ether acetates, alkoxybutyl acetates, and alkyl alkoxy butyl acetates Further, from the viewpoint of having a propylene glycol skeleton, propylene glycol monoalkyl ether acetate, dipropylene glycol monoalkyl ether acetate or the like is preferable. The second solvent is a solvent or cyclopentanone having a 3-methoxypropionic acid structure represented by CH3OCH2CH2-COO- in the molecule. As the solvent having a 3-methoxypropionic acid structure, it is preferably a compound represented by ch3〇ch2ch2-coo-r. Among them, R is preferably an alkyl group having 1 to 5 carbon atoms. The second solvent is preferably a boiling point of from 140 ° C to 180 ° C at normal pressure. Specifically, for example, the second solvent having a 3-methoxypropionic acid skeleton has a boiling point of from 140 ° C to 180 ° C at normal pressure. Specific examples of the solvent having a 3-methoxypropionic acid structure as the second solvent are, for example, methyl 3-methoxypropionate, ethyl 3-methoxypropionate, and 3-methoxypropionic acid Examples of the ester, butyl 3-methoxypropionate, and the like, and methyl 3-methoxypropionate is preferred. Further, as the third solvent, propylene glycol diacetate of 1 to 15% by weight or 1,3-butylene glycol of 0.1 to 5% by weight is blended. The reason why the structure of the first solvent is selected is that the boiling point and the dissolution parameter of the resin composition are selected, and the change in the structure is obtained by selecting the monovalent or divalent alcohol as a raw material, which is relatively inexpensive and economical. Ideal example. Further, the reason for the structure having a propylene glycol skeleton is that the reason for the adverse effects on the environment other than the above-mentioned reasons is small. The reason why 3-methyl methoxypropionate or cyclopentanone is selected as the second solvent is that not only the dispersibility of the black pigment in the resin composition is good but also the solubility of the acrylic acid resin is high, and the adhesion of the solid component can be prevented. Liquid-Soluble Coating Equipment-10-200903047 The indenter of the discharge portion of the photoresist is set to be effectively applied continuously to the substrate. The reason why propylene glycol diacetate or 1,3-butanediol is selected as the third solvent is that the boiling point of the normal pressure is 1 70 ° C, which not only prevents the discharge portion of the photoresist ink in the corresponding liquid-saving coating device. The drying of the indenter and adjusting the drying speed of the coating film to an appropriate range can effectively reduce the number of dry spots. The boiling point of the solvent is preferably a certain range, and the range is different in the first solvent, the second solvent, and the third solvent. Further, it is preferred that the boiling point of each solvent is in the above range, and that the solvent may be a mixed solvent of a plurality of compounds. The boiling point range is closely related to the drying property of the coating film. When the boiling point of each solvent is out of this range, the drying property is too high or too low to obtain good coatability. Further, the reason why the first solvent, the second solvent, and the third solvent have different boiling points is to adjust the drying speed of the coating film to an appropriate range to reduce the dry spots. The content of each solvent in the total solvent is 45 to 75 wt% of the first solvent, 25 to 40% when the second solvent is methyl 3-methoxypropionate, and 20 to 35 wt% when cyclopentanone is used. When the third solvent is 1 to 15% by weight in the case of propylene glycol diacetate (PGDA) and 0.1 to 5% by weight in the case of 1,3-butanediol (1,3BGDA), the first solvent is preferably 55 to 70. The weight %, the second solvent is 25 to 35% by weight in the case of methyl 3-methoxypropionate, 20 to 30% by weight in the case of cyclopentanone, and 5 to 10% by weight and 1 in the case where the third solvent is PGDA. When 3BGDA is 1 to 3 wt%. The total of the first solvent to the third solvent is preferably 70 to 1% by weight, and preferably 80 to 100% by weight, based on the total solvent content of the total solvent. When it is less than 100% by weight, other solvents can be used for -11 - 200903047 without impairing the effects of the present invention. Examples of other solvents include, for example, ester solvents, ether solvents, alcohol solvents, ketone solvents, aliphatic solvents, aromatic solvents, nitrogen-containing solvents, sulfur-containing solvents, and the like. An ester solvent, an ether solvent, or an alcohol solvent is preferred. These can be used alone or in combination of two or more. Further, the boiling point of other solvents at a normal pressure of 1 20 to 240 ° C is preferably 'dissolved parameter 値 8.0 to 1 l. iHcal / cm 2 : ^ · 5 is suitable.
