Synthetic example 1

[0299]

[0300]On the one hand, prepare a flask equipped with a stirrer, a thermometer, a condensing reflux tube, a dropping funnel, and a nitrogen introduction tube; on the other hand, as a monomer dropping funnel, put 3,4-epoxytricyclodecan-8-yl 40 parts by weight of a mixture (50:50 molar ratio) of (meth)acrylate (chemical formula 1) and 3,4-epoxytricyclodecan-9-yl (meth)acrylate (chemical formula 2), methyl After 50 parts by weight of methyl acrylate, 40 parts by weight of acrylic acid, 70 parts by weight of vinyl toluene, 4 parts by weight of tert-butyl peroxy-2-ethylhexanoate, and 40 parts by weight of propylene glycol monomethyl ether acetate (PGMEA) Stirring and mixing for later use, as a drop tank for chain transfer agent, 6 parts by weight of n-dodecanemercaptan and 24 parts by weight of PGMEA were put in and stirred and mixed for later use. Then, 395 parts by weight of PGMEA was introduced into the flask, and the atmosphere in the flask was changed from air to nit...

[0301]

[0302] Introduce 182 g of propylene glycol monomethyl ether acetate into a flask equipped with a stirrer, a thermometer, a condensing reflux tube, a dropping funnel, and a nitrogen gas introduction tube, and after changing the atmosphere in the flask from air to nitrogen, the temperature is raised to 100° C., and then from 66.0 g (0.3 mol) of monomethacrylate (FA-513M manufactured by Hitachi Chemical Co., Ltd.) containing (B-2-1) tricyclodecane skeleton, (B -2-2) Azobisiso For a solution of 3.6 g of butyronitrile, stirring was continued for 5 hours from 100°C. Next, the atmosphere in the flask was changed from nitrogen to air, and 42.0 g (0.28 moles) of (B-2-4) glycidyl methacrylate, 0.9 g of tris(dimethylamino)methylphenol, and The reaction of 0.145 g of hydroquinone was continued at 110° C. for 6 hours, and a resin (B-2-a) having an acid value of 170.7 mgKOH / g of the solid content was obtained. The polystyrene equivalent weight average molecular weight measured ...

Abstract

The invention relates to a colored photosensitive resin composition and a color filter manufactured by the same, and specifically relates to the colored photosensitive resin composition comprising a coloring agent, alkali-soluble resin, a photo-polymerization compound, and a photo-polymerization initiator and a solvent. By the use of the green pigment, first resin and second resin in the colored photosensitive resin composition, the color filter has a wide color representation range, is high in contrast ratio and brightness, and is excellent in tinting strength, image definition performance, developing performance, sensitivity and sealing performance, wherein the green pigment includes pigment green 7 and is included in the coloring agent, the first resin includes an epoxy group and is included in the alkali-soluble resin, the second resin includes an acid group capable of reacting with the epoxy group, and the acid value of the acid group is 170-300 mgKOH / g.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition and a color filter produced therefrom. More specifically, it relates to a coloring that exhibits high contrast and brightness and is excellent in tinting strength, pattern formation, development, sensitivity, and adhesion A photosensitive resin composition and a color filter manufactured therefrom. Background technique [0002] Recently, a liquid crystal display device is a technology-intensive product with low power consumption and good portability, and has attracted attention as a next-generation high-end display device with high added value. [0003] Among such liquid crystal display devices, active-matrix liquid crystal display devices equipped with thin-film transistors, which are switching elements capable of adjusting voltage on / off for each pixel (pixel), are superior in resolution and video display capability. Excellent and most concerned. [0004] Generally, a liqui...
