Problems solved by technology

[0004] However, when a colored photosensitive resin composition containing a dye as a colorant is used to manufacture a color filter, the light resistance and heat resistance of the dye are weak, and color difference often occurs, and the developing speed is slow, and the sensitivity is insufficient, which frequently occurs. The problem that the formed pattern is peeled off when the development process is carried out with an alkaline developer

Synthetic example 1

[0155] Synthesis Example 1: Synthesis of Compound M-1

[0156] a) Synthesis of M-1a compound

[0157] Put 50.0 parts by weight of di-tert-butyl-2-hydroxysuccinate (di-tert-butyl-2-hydroxysuccinate), 24.65 parts by weight of triethylamine, and 300.0 parts by weight of tetrahydrofuran into a four-neck round bottom flask equipped with a cooling tube and a stirrer. parts by weight, while stirring, the internal temperature of the reactor was cooled to 0°C. Next, 25.46 parts by weight of methacryloyl chloride was dropped over 30 minutes. After the dropwise addition, the reaction temperature was raised to room temperature. Then, the reaction was continued for 5 hours. After completion of the reaction, 150 parts by weight of a saturated aqueous sodium bicarbonate solution was added to the reaction liquid, and then 200 parts by weight of ethyl acetate was added for extraction. The aforementioned extract was washed with 150 parts by weight of saturated brine, dried over anhydrous ma...

[0163] Synthesis Example 2: Synthesis of Alkali-Soluble Resin

[0164] 120 parts by weight of propylene glycol monomethyl ether acetate, 80 parts by weight of propylene glycol monomethyl ether, 2 parts by weight of AIBN, 20.0 parts by weight of the aforementioned M-1 compound, 60.0 parts by weight of 4-methylstyrene, 10 parts by weight of benzyl methacrylate, 10 parts by weight of methyl methacrylate, 3 parts by weight of n-dodecyl mercaptan, the atmosphere of the flask was replaced with nitrogen . Then, stirring was performed, and the temperature of the reaction liquid was raised to 80° C., followed by reaction for 8 hours. The acid value of the solid content of the alkali-soluble resin synthesized in this way was 99.2 mgKOH / g, and the weight average molecular weight Mw measured by GPC was about 9200.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a colored pattern formed from the composition, a color filter including the colored pattern, and a liquid crystal display device and an imaging element including the color filter. Background technique [0002] Color filters are widely used in imaging elements, liquid crystal display devices, and the like, and their range of applications is rapidly expanding. Color filters used in color liquid crystal display devices, imaging elements, etc. are generally produced by uniformly applying colorants containing colorants corresponding to red, green, and blue colors by spin coating on a substrate on which a black matrix pattern is formed. The photosensitive resin composition is colored, then heat-dried (hereinafter sometimes referred to as pre-baking) to form a coating film, the coating film is exposed, developed, and heat-cured as necessary (hereinafter sometimes referred to as secon...
