Synthetic example 1

[0208] Synthesis Example 1: Triazine Compound

[0209] As a triazine derivative, a compound of the following Chemical Formula 13 was produced as follows.

[0210] Add 18.4 parts by weight of 2-chloro-4,6-diamino-1,3,5-triazine and 21 parts by weight of 3-(2-ethylhexyloxy)propylamine to 100 parts by weight of water. React for 1 hour. The resulting reactant was reacted at 85°C for 5 hours. The residue obtained by leaching the obtained reactant was washed with water, and then left to stand overnight in a thermostat at 100° C. for drying to obtain a compound of the following chemical formula 13.

Synthetic example 2

[0213] Synthesis example 2: the compound of chemical formula 3

[0214] As the oxime compound, the compound of Chemical Formula 3 was produced as follows.

[0215] Reactant 1

[0216] Under a nitrogen atmosphere, 200.0 g of fluorene, 268.8 g of potassium hydroxide, and 19.9 g of potassium iodide were dissolved in 1 L of anhydrous dimethyl sulfoxide, and the reactant was maintained at 15° C., and then bromoethane 283.3 g was slowly added over 2 hours. g. The reaction was stirred at 15°C for 1 hour. Then, after adding 2 L of distilled water to the reactant and stirring for 30 minutes, the product was extracted with 2 L of dichloromethane, and after the extracted organic layer was washed twice with 2 L of distilled water, the recovered organic layer was dried with anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure, and the resulting product was fractionally distilled under reduced pressure to obtain 248.6 g of a pale yellow reactant 1 (9,9-...

Synthetic example 3

[0223] Synthesis Example 3: Resin B-1

[0224] Prepare a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen introduction tube. On the other hand, as a monomer dropping funnel, prepare 74.8 g (0.20 mol) of benzylmaleimide and 43.2 g of acrylic acid. (0.30 mol), 118.0 g (0.50 mol) of vinyltoluene, 4 g of tert-butyl peroxy-2-ethylhexanoate, and 40 g of propylene glycol monomethyl ether acetate (PGMEA) were charged and mixed with stirring, As a chain transfer agent dropping tank, what was prepared by adding 6 g of n-dodecane mercaptan and 24 g of PGMEA and stirring and mixing them was prepared. Thereafter, 395 g of PGMEA was introduced into the flask, and the atmosphere in the flask was replaced with nitrogen from air, and then the temperature of the flask was raised to 90° C. while stirring. Next, the monomer and the chain transfer agent were added dropwise from the dropping funnel. During the dropwise addition, each was carried ...

Abstract

The invention provides a colored photosensitive resin composition, a color filter and an image display device, which are produced from the colored photosensitive resin composition. The colored photosensitive resin composition includes a colorant, a binding agent resin, a photo-polymerizable compound, a photo-polymerization initiator, and a solvent, wherein the photo-polymerization initiator includes an oxime compound which has absorption band at a zone of higher than 300 nm and an acetophenone compound which has absorption band at a zone of lower than 300 nm. The colored photosensitive resin composition can be fully cured even through a low-temperature sintering step. The color filter formed therewith has excellent solvent resistance, and is free of water strips and lamination residues.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter, and an image display device. More specifically, it relates to a coloring photosensitive resin composition, a color filter, and an image display device. Colored photosensitive resin composition of streaks and lamination residue, color filter formed using the same, and image display device including the color filter. Background technique [0002] Color filters are widely used in imaging elements, liquid crystal displays (LCDs), and the like, and their application range is rapidly expanding. In particular, in LCDs where the use of color filters is expanding, color filters are one of the most important parts for reproducing colors. In the LCD manufacturing process, it is used to improve the processability of productivity and the manufacture of color filters with excellent product reliability. Methods are also being researched continuously. [0003] In recent year...
