Embodiment

[0321] Hereinafter, an Example is given and the embodiment of this invention is demonstrated more concretely. However, the present invention is not limited to the following examples.

[0322]

Synthetic example 1

[0324] [Synthesis of Monomer (1)]

[0325] Monomer (1) was synthesized using the following procedure according to the following scheme.

[0326]

[0327] Install a stirrer, a thermometer, a dropping funnel, and a reflux cooling tube in a 300mL four-necked flask with a stirrer, put 100g of water, 14g of sodium dithionite (0.080 mol), and 12.1g of triethylamine (0.12 mol) . Thereafter, a solution obtained by dissolving 9.56 g (0.040 mol) of 5-bromo-4,4,5,5-tetrafluoropentan-1-ol in 80 g of acetonitrile was added dropwise from the dropping funnel over 15 minutes while stirring. . Thereafter, it was heated in an oil bath and reacted at an internal temperature of 60° C. for 5 hours under a nitrogen stream. After the reaction was completed, it was cooled to 25° C., and after standing for 15 minutes, the reaction liquid separated into two layers. The organic layer was separated, and 100 g of acetonitrile was further added to the water layer. The organic layer was separated, co...

Synthetic example 2

[0338] [Synthesis of Monomer (2)]

[0339] According to the following scheme, the monomer (2) was synthesized by the following procedure.

[0340]

[0341] A thermometer and a dropping funnel were attached to a 300 mL three-necked flask with a stirring bar, and 23.0 g of methacryloyl chloride (0.220 mol) and 160 mL of methylene chloride were added and uniformly dissolved in a nitrogen atmosphere. This solution was cooled to 0° C., 30.4 g (0.300 mol) of triethylamine was added, and the mixture was further stirred. Next, after adding 34.4 g (0.200 mol) of 2-iodoethanol dropwise over 30 minutes, the reaction solution was heated up to room temperature and stirred for 2 hours. Thereafter, the reaction solution was poured into 300 mL of saturated ammonium chloride aqueous solution, the organic layer was separated, and the aqueous layer was extracted twice with 200 mL of dichloromethane. It was combined with the organic layer, washed sequentially with 500 g of saturated aqueous ...

Abstract

Provided is a colored composition suitable for the formation of a colored cured film having both heat resistance and solvent resistance. A colored composition comprising (A) a coloring agent and (B) a polymerizable compound, wherein the coloring agent contains a compound having a structural unit represented by formula (1). [In formula (1), R1 represents a hydrogen atom, a methyl group or a trifluoromethyl group, and R2 and R3 independently represent a hydrogen atom, a halo group or a substituted or unsubstituted hydrocarbon group, wherein R2 and / or R3 represents a halo group or a halo-group-substituted hydrocarbon group; A represents a bivalent group; G represents a bivalent hydrocarbon group or a single bond, wherein the bivalent hydrocarbon group may have a linking group selected from a -O- group, a -S- group, a -CO- group and a -NR7- group between a C-C bond; R7 represents a hydrogen atom or a substituted or unsubstituted hydrocarbon group; Zm+ represents a cationic chromophore; m represents a natural number of 1 to 3; and p represents a natural number of 1 to 8.]

Description

technical field [0001] The present invention relates to a colored composition, a colored cured film, and a display element, and more specifically, to a colored composition used to form a transmissive or reflective color liquid crystal display element, a solid-state imaging element, and an organic EL display element. , a colored cured film used in electronic paper and the like, and relates to a colored cured film formed using the colored composition, and a display element including the colored cured film. Background technique [0002] It is known that when a colored radiation-sensitizing composition is used to manufacture a color filter, a pigment-dispersed colored radiation-sensitizing composition is coated on a substrate and dried, and then irradiated (hereinafter referred to as "exposure") with radiation to make the color filter A method of obtaining pixels of each color by developing a dried coating film into a desired pattern shape (for example, refer to Patent Documents...
