Embodiment

[0318] The present invention will be further described in detail through examples below, but the present invention is not limited by these examples. In Examples and Comparative Examples, % and parts indicating content or usage-amount are based on mass unless otherwise specified.

Synthetic example 1

[0320]

[0321] In a flask with a condensing tube and a stirring device, 15 parts of a mixture of a compound represented by formula (A0-1) and a compound represented by formula (A0-2) (manufactured by Zhongwaihuacheng), 150 parts of chloroform and N, N- To 8.9 parts of dimethylformamide, 10.9 parts of thionyl chloride were added dropwise while maintaining the temperature below 20°C under stirring. After completion of the dropwise addition, the temperature was raised to 50°C, and the reaction was maintained at this temperature for 5 hours, and then cooled to 20°C. While maintaining the cooled reaction solution at 20° C. or lower with stirring, a mixed solution of 12.5 parts of 2-ethylhexylamine and 22.1 parts of triethylamine was added dropwise. Then, stirring was carried out at this temperature for 5 hours to make it react. Then, after distilling off the solvent from the obtained reaction mixture with a rotary evaporator, a small amount of methanol was added and vigorously ...

Synthetic example 2

[0327]

[0328] In a 1L flask with a stirrer, a thermometer, a reflux condenser and a dropping funnel, flow nitrogen gas at 0.02L / min to obtain a nitrogen atmosphere, add 305 parts of propylene glycol monomethyl ether acetate, and heat to 70°C. Then dissolve in 60 parts of methacrylic acid, 3,4-epoxy tricyclic [5.2.1.0 2.6 ] decyl acrylate (mix the compound represented by the following formula (B-1-1) and the compound represented by formula (B-1-2) at a molar ratio of 50:50.) 240 parts, and propylene glycol monomethyl 140 parts of ether acetate was used to prepare a solution, and the solution was dropped into a flask kept at 70° C. over 4 hours using a dropping funnel. On the other hand, using another dropping funnel, a solution obtained by dissolving 30 parts of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) in 225 parts of ethyl lactate was prepared over 4 hours. Add dropwise to the flask. After the solution of the polymerization initiator was added...

Abstract

The invention provides a coloring cured resin composite, comprising xanthene dyes (A), adhesive resins (B), photopolymerized compound (C1) having 5-8 olefinic unsaturated double-bonds, photopolymerized compound (C2) having 1-4 olefinic unsaturated double-bonds, a photopolymerized initiator (D), and a solvent (E). The content of (C1) is 10-95 mass% of the total content of (C1) and (C2). The redissolving performance of the composite to the solvent is good.

Description

technical field [0001] The present invention relates to a colored curable resin composition suitable for forming a colored image constituting a color filter used for a liquid crystal display element or a solid-state imaging element. Background technique [0002] As a method of producing a color filter based on a colored curable resin composition, it is known to apply the colored curable resin composition on a substrate using a slit nozzle to form a coating film, followed by exposure and development. , post-curing and a series of treatments, the method of making an image from the coating film. [0003] However, in the above-described production method, the colored curable resin composition may dry and a dried product may be generated at the tip portion of the slit nozzle. Therefore, when a colored curable resin composition is applied using a slit nozzle, when a dry product is generated at the tip of the slit nozzle, the property of being able to wash the dried product with a...
