Synthetic example 1

[0159] Synthesis Example 1: Compound of colorant (A-1)

[0160] The following reactions were carried out under a nitrogen atmosphere. After putting 15.3 parts of N-methylaniline (manufactured by Tokyo Chemical Industry Co., Ltd.) and 60 parts of N,N-dimethylformamide into a flask equipped with a condenser and a stirring device, the mixed solution was ice-cooled. Under ice cooling, 5.7 parts of 60% sodium hydride (manufactured by Tokyo Chemical Industry Co., Ltd.) was added little by little over 30 minutes, and stirred for 1 hour while raising the temperature to room temperature. 10.4 parts of 4,4'-difluorobenzophenone (manufactured by Tokyo Chemical Industry Co., Ltd.) was added little by little to the reaction solution, and stirred at room temperature for 24 hours. After adding the reaction liquid to 200 parts of ice water little by little, it was left standing at room temperature for 15 hours, and the water was removed by decantation to obtain a viscous solid as a residue. T...

[0171] Synthesis Example 1-1: Resin for Colored Dispersion Liquid (B)

[0172] In a flask equipped with a reflux condenser, a dropping funnel and a stirrer, a nitrogen atmosphere was made by flowing nitrogen gas at 0.02 L / min, and 200 parts of 3-methoxy-1-butanol and 3-methoxybutanol were added. 105 parts of glycyl acetate were heated to 70°C while stirring. Next, 60 parts of methacrylic acid, 3,4-epoxy tricyclic 5.2.1.O 2,6 ] 240 parts of decyl acrylate was dissolved in 140 parts of 3-methoxybutyl acetate to prepare a solution, and the dissolved solution was dropped into a flask kept at 70° C. using a dropping funnel over 4 hours. On the other hand, 30 parts of polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) was dissolved in 225 parts of 3-methoxybutyl acetate, and the resulting solution was used for another drop The funnel was dropped into the flask over 4 hours. After the dropwise addition of the polymerization initiator solution was completed, the solution ...

Description

Technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter, and an image display device provided with the color filter. Background technique [0002] Color filters are widely used in imaging elements, liquid crystal display devices, etc., and their applications are rapidly expanding. Color filters used in color liquid crystal display devices, imaging elements, etc. are usually manufactured as follows: a black matrix patterned substrate is uniformly coated with colorants corresponding to each of red, green, and blue by spin coating After the colored photosensitive resin composition, the coating film formed by heating and drying (hereinafter, sometimes referred to as pre-baking) is exposed and developed, and further heated and cured as necessary (hereinafter, sometimes referred to as post-baking), This operation is repeated for each color to form pixels of each color. At this time, a process of removing the solvent of the re...
