Embodiment

[0383] Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to these Examples. In the examples, % and parts indicating the content or the amount used are mass standards unless otherwise specified.

Synthetic example 1

[0385] An appropriate amount of nitrogen was poured into a flask equipped with a reflux condenser, a dropping funnel, and a stirrer to form a nitrogen atmosphere, 100 parts of propylene glycol monomethyl ether acetate was added, and the mixture was heated to 85° C. while stirring. Then, 19 parts of methacrylic acid, 3,4-epoxytricyclo[5.2.1.0 2,6 ]decane-8-yl acrylate and 3,4-epoxytricyclo[5.2.1.0 2,6 ] 171 parts of a mixture of decane-9-yl acrylate (the molar ratio is 50:50) (trade name "E-DCPA", produced by Daicel Co., Ltd.) was dissolved in propylene glycol monomethyl ether acetate 40 part solution. On the other hand, 26 parts of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) dissolved in propylene glycol monomethyl ether ethyl alcohol was dripped into the flask over about 5 hours using another drip pump. A solution formed from 120 parts of acid ester. After the dropwise addition of the polymerization initiator was completed, it was kept at the same t...

Abstract

A colored photosensitive resin composition comprising a coloring agent (A), an alkali-soluble resin (B), a polymerizable compound (C), a polymerization initiator (D) and a solvent (E), wherein the coloring agent (A) comprises a thiazole dye (A-I), and the alkali-soluble resin (B) is a copolymer containing a constituent unit derived from at least one monomer (a) selected from the group consisting of an unsaturated carboxylic acid and an unsaturated carboxylic acid anhydride. [In formula (A-I), X represents a nitrogen atom or CH; R41 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R42 represents a hydrogen atom, a cyano group, a carbamoyl group or the like; R43 represents an oxygen atom, C(CN)2 or the like; and R44 to R46 independently represent a hydrogen atom, an alkyl group having 1 to 20 carbon atoms which may be substituted by an amino group or a halogen atom, or the like.]

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition. Background technique [0002] For example, the colored photosensitive resin composition is used for the production of color filters such as liquid crystal display devices and solid-state imaging devices. As such a colored photosensitive resin composition, a colored photosensitive resin composition containing a thiazole dye as a colorant and an alkali-soluble resin having a phenolic hydroxyl group as a binder resin is known (JP2008-242325-A) . [0003] The brightness (brightness) of the color filter obtained from the above-mentioned conventionally known colored photosensitive resin composition is not necessarily sufficient. Contents of the invention [0004] The present invention includes the following. [0005] [1] A colored photosensitive resin composition comprising a colorant (A), an alkali-soluble resin (B), a polymerizable compound (C), a polymerization initiator (D)...
