INSTRUCTIONS OF THE INVENTION [Technical Field] The present invention relates to a linear composition for sensitive layer formation, a color filter, and a color liquid crystal display element, which are more detailed and are used for forming a transmissive or reflective type. a sensitive radiation linear composition of a color layer of a color filter such as a color liquid crystal display device or a color image sensor device, a color furnace sheet having a coloring layer formed using the light ray-sensitive composition, and a color filter having the color filter A color liquid crystal display element of a sheet. [Prior Art] A method of forming a color filter using a coloring-sensitive radiation linear resin composition, for example, forming a coating film of a color-sensitive radiation resin composition on a substrate or a substrate on which a light-shielding layer of a desired pattern is formed in advance The illuminating line (hereinafter referred to as "exposure") is irradiated with a reticle having a desired pattern shape, and the unexposed portion is removed by alkali developing liquid development, and then post-baking is performed using a dust-free oven or a hot plate. The method of each color pixel (refer to, for example, Patent Document 1 ' 2) ° In recent years, the color liquid crystal display device has a color purity, and the pigment concentration of the coloring sensitive radiation linear composition tends to be higher and higher. The problem of residue or texture contamination on the substrate of the unexposed portion or on the light shielding layer during development is remarkable. At the same time, when the concentration of the pigment contained in the linear composition of the coloring sensitive radiation is increased, the solubility of the coating film to the alkali developing solution tends to be remarkably lowered. Therefore, when the image is developed by the spray imaging method, the coating film of the unexposed portion which has been removed by peeling is not completely dissolved in the developing tank, and floats, and is reattached to the color filter in the foreign matter form -6-200923581. On, it is an important reason for the decline in product yield. In addition, with the high contrast of the color liquid crystal display device, the pigment contained in the linear composition of the coloring sensitive radiation tends to be more and more micronized, and when the finely divided pigment is to be stably dispersed, a higher dispersion of the amine price can be used. Agent. However, when a dispersing agent having a high amine price is used, the development of the alkali developing solution itself is difficult, and practical use cannot be achieved. Therefore, there is a strong demand for a sensitized radiation resin composition for a color filter which can cope with various problems caused by high color purity and high contrast in recent years. Further, in the case of the problem of residue or texture contamination on the substrate of the unexposed portion or on the light shielding layer during development, for example, as disclosed in Patent Document 3, a polyfunctional monomer having a carboxyl group can be used. However, the pentaerythritol triacrylate disclosed in Patent Document 3 and the monomeric ester compound containing a free carboxyl group of succinic acid are used when a pigment-containing linear composition having a high pigment concentration of 30% by weight or more in the total solid content is used. When the hardening of the coating film is insufficient, the surface smoothness of the pattern is significantly impaired, and as a result, problems such as poor alignment of the liquid crystal occur. In addition, as disclosed in Patent Document 4, the photocurable compound having one or more acidic functional groups and three or more photocurable functional groups can improve the developability of the curable resin composition for coloring patterns. . However, the above problems with a resin composition of a red, green or blue pattern such as a pigment having a pigment content of more than 30% by weight in the total solid content do not reveal any effective solution. 200923581 Therefore, there is a strong need to develop a color-sensitive radiation linear resin composition which can meet various requirements such as development performance and product yield in the manufacture of color filters in recent years, and the surface smoothness of the pattern is good.

That is, the solution in a good solvent after polymerization, if necessary, removes insoluble impurities by filtration or centrifugation, and then injects a large amount (usually 5 to 10 times the volume of the polymer solution) of a precipitant (poor solvent). The copolymer was reprecipitated and purified.
