Description

[Technical Field] The present invention relates to a color filter for a color liquid crystal display device or the like, a pigment dispersion for a color filter for a black matrix, and a color filter for containing the color filter. The color filter of the pigment dispersion is a pigment dispersion resist composition. [Prior Art] The color liquid crystal display device has the characteristics of being lightweight and capable of reducing power consumption. In recent years, it has been devoted to the development of temperature technology, and it is desired to continue the improvement of high brightness, high definition, and high contrast. As a result, the stability performance can be maintained in various fields from small screens to large screens, and it is considered that the overall balance of performance is high, which is related to the expansion of use. However, the commercialization of an image display device using an organic EL or the use of an organic EL is also considered, and there are still many technical problems that have to be overcome in order to make the color liquid crystal display device more widely used. For example, one of the topics is to improve color reproducibility. In order to improve color reproducibility, it is required that each color pixel of the basic coffee displayed on the display itself has high color purity and high contrast. In the color liquid crystal display device, the white light emitted by the light source such as the backlight is first, and the portion corresponding to each color pixel of the material RGB is controlled by the liquid crystal to control the slit, and the color light film having the color film provided through (10) is transmitted. This colores and displays the pixels of each color on the display. Therefore, such a white light is colored by a color filter (colored film). 201030104 The color purity of the colored light is increased. The color purity of the color is required to be high. The colored film is set on the color filter. When there are coarse round particles in the film, the light transmitted through the light will be confused (depolarization), resulting in

The ratio is reduced. Therefore, it is necessary to have a rough particle in the color film of the skirt. Recently, pigments have been used as color materials for coloring films. In order to increase the factors such as color developability (chroma) or transparency (lightness) associated with color purity, it is necessary to disperse the pigment more finely in order to suppress the depolarization.

Further, in the color filter, if the colored film overlaps, the color purity is lowered by bleeding, and if there is a gap, the contrast is lowered by light leakage. Therefore, in order to prevent such a situation, the shading between the colored films is provided, and a black matrix is provided. Therefore, the performance of the formation of the black matrix also has a significant influence on the improvement of color reproducibility. In the black matrix, the light-shielding coating film is formed into a lattice shape or a belt shape. The light-shielding coating film is as thin as possible and is required to have a narrow width (also referred to as a fine line) and the edge of the film is required to be sharp and linear. Recently, a coating agent obtained by using a black pigment such as carbon black as a light-shielding material is used for the formation of a black matrix. In the coating agent for forming a black matrix, in order to maintain high light transmittance for the film, it is necessary to increase the concentration of the light shielding material. Further, such a coating agent is of a type which is cured by ultraviolet rays or the like, and is subjected to a development step of removing the uncured portion to form a black matrix of fine lines. In order to improve the formability of such a film which is thin and has a sharp edge and a high linearity, it is necessary to ensure that the hardened portion is surely retained, and that the development property of the unhardened portion is surely removed. However, when the pigment is dispersed in the coating agent, along with the surface area of the pigment 5 201030104

The amount of the pigment dispersing aid used exceeds the above range, and the pigment dispersion effect is dispersed. <Method for Producing Pigment Dispersion> An example of a method for producing a pigment dispersion using the above materials will be described below. In order to produce the pigment dispersion of the present invention, a conventionally known production method can be used, for example, Manufactured by the following method. Firstly, a mixture of a pigment, a pigment dispersant, an organic solvent, and optionally a pigment dispersing aid is obtained. The mixture is kneaded and dispersed by various dispersers such as a roll mill kneader, a south speed mixing device bead mill, a ball mill, a sand mill, a super 9-wave disperser, a high-pressure disperser, etc. to obtain a pigment dispersion. Further, the pigment dispersion of the present invention may contain a binder resin (alkali-soluble resin, photopolymerizable compound, etc.) in advance. <Pigment-dispersing photoresist composition for color filters> Next, for the color filter containing the above-mentioned color filter The color dispersion sheet of the pigment dispersion is described in more detail by the pigment dispersion resist composition. 18 201030104 The pigment dispersion photosensitive composition for the above color filter is composed of a photoresist having active energy ray hardenability and being developable. In addition to the above pigment dispersion, a soluble resin, a photopolymerizable person, a photopolymerization initiator, an optional organic solvent, and a thermal polymerization inhibitor may be appropriately contained: for adhesion to a substrate Various additives such as an improved decane coupling agent or a titanate coupling agent, an ultraviolet absorber, an antioxidant, etc. Color filter used in the black matrix of the present invention The pigment dispersion-dispersing composition for a sheet is used in a black matrix application, and the amount of the pigment used in the composition is relative to the total solid content of the pigment dispersion resist composition of the color filter, and the mass fraction is used. The total amount is preferably from 5 to 6 % by mass, preferably from 10 to 30% by mass. Further, when used in the formation of color pixels of a color light-draining sheet, the organic pigment in the raw material is used in 4, as opposed to The total solid content of the color 泸m pigment dispersion resist composition, and the total amount of the organic pigment produced is preferably 5 to 8 〇 mass%, preferably 2 〇 to 5 〇 mass%. In the pigment dispersion resist composition for a color filter, the amount of the pigment dispersant used is usually 1 to 2 parts by mass 'preferably 1 to 60 parts by mass based on 100 parts by mass of the organic pigment. If it is less than i part by mass, the pigment dispersibility sometimes decreases. On the other hand, when it exceeds 200 parts by mass, the developability is lowered. In the pigment dispersion resist composition for a color filter, the amount of the pigment dispersing aid to be used is usually 30% by mass or less, preferably 0.1 to 20% by mass based on the coloring pigment. Even if it exceeds 3% by mass, the pigment dispersion effect tends to be not improved. 19 201030104 (alkali-soluble resin) Next, in the case of the alkali-soluble resin constituting the pigment-dispersed photoresist composition for a color filter of the present invention for the purpose of imparting development characteristics and the like, the development processing step is performed when a color calender sheet is produced. The developer to be used is not particularly limited as long as it is soluble in the alkali developer. Among them, an alkali-soluble resin having a carboxyl group is preferred, and a copolymer of an ethylenically unsaturated monomer having more than one carboxyl group and another copolymerizable ethylenically unsaturated monomer is particularly preferred. Specifically, an ethyl beta olefinically unsaturated monomer having a carboxyl group such as acrylic acid or mercaptoacrylic acid, and a copolymerizable with an ethylenically unsaturated monomer having the carboxyl group are selected from the group consisting of styrene and 2-hydroxyethyl acrylate. 2, hydroxyethyl methacrylate, allyl acrylate, allyl methacrylate, benzyl acrylate, benzyl methacrylate, cyclohexyl acrylate, cyclohexyl methacrylate, glyceryl monoacrylate, Copolymer of at least one ethylenically unsaturated monomer in the group consisting of glyceryl methacrylate, Ν_stupyl maleimide, polystyrene macromonomer and polymethyl methacrylate macromonomer . The acid value of the above copolymer is preferably from 50 to 300 mg K 〇 H / g. In this case, if the acid value is less than 50 mgKOH/g', the solubility of the photoresist composition to the alkali developer tends to be lowered. On the other hand, when it exceeds 3 〇〇 mg K 〇 H / g, the solubility in the developer is too large, and when the development is performed with an alkali developer, the colored layer may be detached from the substrate or the film on the surface of the colored layer may become The tendency of the thick wheel.

The weight average molecular weight of the alkali-soluble resin is less than 1,0 0 ', and the solubility of the developer is removed to remove the π too much, and sometimes the hardened photoresist film is dissolved. On the other hand, when it exceeds 100,000, the solubility in an organic solvent falls, and scumming or film residue may occur on the uncured portion of the photoresist film or on the light shielding layer, and sometimes the photoresist composition may be present. The viscosity will become higher. In the pigment dispersion resist composition for a color filter, the amount of the above-mentioned soluble resin used is usually 10 to 1,000 parts by mass, preferably 20 to 500 parts by mass based on 1 part by mass of the total pigment used. Parts by mass. When the amount of the alkali-soluble resin used is less than 10 parts by mass, for example, alkali developability may be lowered, or peeling or film residue may occur on the substrate or the light-shielding layer of the unexposed portion. On the other hand, if the amount of the pigment exceeds 1, the amount of the pigment is relatively lowered, so that when the film is formed, it may be difficult to achieve the target color concentration.
