Problems solved by technology

[0008] In addition, in the photosensitive coloring composition, while maintaining the dispersion stability of the coloring material, it is necessary to achieve high sensitivity of the photosensitive coloring composition with a high concentration and good pattern formation (unexposed partial solubility, shape maintenance of the photocured part, etc.), this requirement cannot be achieved only by changing the design of the photosensitive transparent resin

Embodiment

[0078] The present invention will be described below based on examples, but the present invention is not limited to these examples. In addition, in the following examples and comparative examples, "part" means "part by weight". The molecular weight of the resin is the weight average molecular weight in terms of polystyrene measured by GPC (gel permeation chromatography).

Synthetic example 1

[0080] Add 560 parts of cyclohexanone into the reaction container, inject nitrogen into the container, and raise the temperature to 80°C at the same time, at the same temperature, drop 34.0 parts of methacrylic acid, 23.0 parts of methyl methacrylate, 23.0 parts of n-butyl methacrylate, 22.0 parts of ethylene oxide-modified acrylate of p-cumylphenol ("Aronix M110" manufactured by Toagosei Co., Ltd.) as the monomer (a), 47.0 parts of glycerol monomethyl The mixture of acrylate and 4.0 parts of 2,2'-azobisisobutyronitrile was polymerized. After the dropwise addition, react at 80°C for 3 hours, then add a solution obtained by dissolving 1.0 part of azobisisobutyronitrile in 55 parts of cyclohexanone, and continue the reaction at 80°C for 1 hour to obtain a transparent resin solution.

[0081] Then, a mixture of 32.0 parts of 2-methacryloyl ethyl isocyanate, 0.4 parts of dibutyltin laurate, and 120.0 parts of cyclohexanone was added dropwise to 338 parts of the obtained transpare...

Synthetic example 2

[0083] Add 570 parts of cyclohexanone to the reaction container, inject nitrogen into the container, and raise the temperature to 80°C at the same time. At the same temperature, drop 23.0 parts of methacrylic acid, 23.0 parts of methyl methacrylate, 35.0 parts of Benzyl methacrylate, 22.0 parts of ethylene oxide-modified acrylate of p-cumylphenol as the monomer (a) ("Aronix M110" manufactured by Toagosei Co., Ltd.), 48.0 parts of glycerin monomethacrylic acid The mixture of ester and 3.0 parts of 2,2'-azobisisobutyronitrile was polymerized. After the dropwise addition, react at 80°C for 3 hours, then add a solution obtained by dissolving 1.0 part of azobisisobutyronitrile in 50 parts of cyclohexanone, and continue the reaction at 80°C for 1 hour to obtain a transparent resin solution.

[0084] Then, a mixture of 33.0 parts of 2-methacryloyl ethyl isocyanate, 0.4 parts of dibutyltin laurate, and 130.0 parts of cyclohexanone was added dropwise to 336 parts of the obtained trans...

Abstract

The present invention provides a coloring composition for a color filter, which contains a photosensitive transparent resin, a non-photosensitive transparent resin, a polyfunctional monomer having 3 or more ethylenically unsaturated double bonds, and a coloring material, wherein Based on the total weight of the photosensitive transparent resin, the non-photosensitive transparent resin and the multifunctional monomer, the molar concentration of ethylenically unsaturated double bonds in the coloring composition is 1.0×10-3 mol / g~7.0×10-3 3 mol / g, and the present invention also provides a color filter having color filter segments formed from the above-mentioned coloring composition for color filters.

Description

technical field [0001] The present invention relates to a high-sensitivity photosensitive coloring composition, in particular to a high-sensitivity coloring composition for color filters used in the manufacture of color filters used in color liquid crystal display devices, color imaging tube elements, and the like, and its use The composition forms a color filter. Background technique [0002] The color filter is to arrange two or more fine strip (strip) color filter segments (filter segments) of different colors in parallel or cross on the surface of a transparent substrate such as glass, or to place fine color filter segments Sections are arranged in a constant length and width arrangement. The color filter segments are as fine as several microns to hundreds of microns, and each color is ordered in a prescribed arrangement. [0003] Generally, in a color liquid crystal display device, a transparent electrode for driving liquid crystal is formed on the color filter by vap...
