[0190] Hereinafter, the present invention will be explained in more detail using examples. The "%" and "parts" in the examples refer to mass% and parts by mass unless otherwise specified.

[0191]

Synthetic example 1

[0193] Into a flask equipped with a stirrer, a thermometer, a reflux cooling tube, a dropping funnel, and a nitrogen introduction tube, 571 parts of propylene glycol monomethyl ether acetate was introduced. After the atmosphere in the flask was changed from air to nitrogen, the temperature was raised to 110°C, and then In a monomer mixture composed of 17.6 parts of benzyl methacrylate, 113.7 parts of glycidyl methacrylate, and 22.0 parts of dicyclopentyl methacrylate (FA-513M manufactured by Hitachi Chemical Co., Ltd.), it took 2 hours to The dropping funnel added a solution of 3.6 parts of azobisisobutyronitrile to 153 parts of propylene glycol monomethyl ether acetate to the flask, and then continued stirring at 100°C for 2 hours. Then, the atmosphere in the flask was changed from nitrogen to air, 57.7 parts of acrylic acid, 0.9 parts of tris(dimethylaminomethyl)phenol, and 0.145 parts of hydroquinone were put into the flask, and the reaction was continued at 110°C for 6 hours...

[0197] Into a flask equipped with a stirrer, a thermometer, a reflux cooling tube, a dropping funnel, and a nitrogen introduction tube, 593 parts of propylene glycol monomethyl ether acetate was introduced. After the atmosphere in the flask was changed from air to nitrogen, the temperature was raised to 110°C, and then In a monomer mixture composed of 88.1 parts of benzyl methacrylate, 56.9 parts of glycidyl methacrylate, and 22.0 parts of dicyclopentyl methacrylate (FA-513M manufactured by Hitachi Chemical Co., Ltd.), it took 2 hours to The dropping funnel added a solution of 3.6 parts of azobisisobutyronitrile to 153 parts of propylene glycol monomethyl ether acetate to the flask, and then continued stirring at 100°C for 2 hours. Then, the atmosphere in the flask was changed from nitrogen to air, 28.8 parts of acrylic acid, 0.9 parts of tris(dimethylaminomethyl)phenol, and 0.145 parts of hydroquinone were put into the flask, and the reaction was continued at 110°C for 6 hours....

Abstract

The invention provides a colored photosensitive resin composition, comprising (A), (B), (C), (D), (E) and (F) and enables patterns with excellent resolution and durability. (A) is a colorant, (B) is resin obtained in such a manner that a copolymer obtained by copolymerization of (a) and (b) is reacted with (c) and then with (d), (C) is a copolymerized compound, (D) is a polymerization initiator, (E) is a multifunctional thiol compound, (F) is a solvent, (a) is a monomer having a cyclic ether framework with 2-4 carbon atoms and olefinic unsaturated bonds, (b) is a monomer which has unsaturated bonds that can be copolymerized with (a) and is different from (a), (c) is at least one selected from an unsaturated carboxylic acid and an unsaturated carboxylic acid anhydride, and (d)) is a polybasic acid anhydride.

Description

Technical field [0001] The present invention relates to a colored photosensitive resin composition. Background technique [0002] The colored photosensitive resin composition is used in the production of color filters. Japanese Patent Laid-Open No. 2004-83857 describes that it contains a resin composed of benzyl methacrylate / methacrylic acid copolymer, 2-benzyl-2-dimethylamino-(4-morpholinobenzene). Base)-1-butanone, 4,4'-bis(diethylamino)-benzophenone, pentaerythritol tetra(3-sulfanyl propionate), photopolymerizable compound, solvent, pigment and pigment dispersion Colored photosensitive resin composition of the agent. [0003] In the conventional colored photosensitive resin composition, the resolution and durability of the obtained pattern may not necessarily be satisfactory. Summary of the invention [0004] The present invention provides the following [1] to [9]. [0005] [1] A colored photosensitive resin composition (colored photosensitive resin composition) containing (A),...
