Synthetic example 1

[0161] Add 30 g of methanol to 2 g of dodecylpyridinium chloride, and slowly drop into the completely dissolved solution to dissolve 6 g of phosphotungstic acid hydrate (Aldrich, P4006) in Solution in 25g of water. After the dropwise addition, the precipitate was stirred at 25 to 50°C for 4 hours, and the precipitate was filtered and washed with water. After filtration, it dried in a 50 degreeC vacuum oven for 12 hours, and obtained 8.5 g of following chemical formula A-1. (Synthesis with reference to Eur.J.Inorg.Chem.2014, 21-35.)

[0162] [Chemical formula A-1]

[0163]

Synthetic example 2

[0165] Using Tetrapropylammonium Hydroxide (TCI, Product No. T0171) instead of dodecylpyridinium chloride, 7.3 g of Chemical Formula A-2 was obtained in the same manner as in Synthesis Example 1.

[0166] [Chemical formula A-2]

[0167]

Synthetic example 3

[0168] Synthesis Example 3: Synthesis of Binder Resin (B)

[0169]Add 100 g of propylene glycol monomethyl ether acetate and 100 g of propylene glycol monomethyl ether into a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen introduction pipe, and change the atmosphere in the flask from air to nitrogen. 8.2 g of azobisisobutyronitrile, 3.1 g of monomethacrylate with a tricyclodecane skeleton (FA-513M manufactured by Hitachi Chemical Co., Ltd.), 55.2 g of 2-ethylhexyl acrylate, and 4-methyl 5.9 g of styrene, 85.2 g of glycidyl methacrylate, and 6.0 g of n-dodecanethiol. Then, the temperature of the reaction liquid was raised to 80° C. while stirring, and the reaction was carried out for 4 hours.

[0170] The temperature of the reaction solution was lowered to normal temperature, and the atmosphere of the flask was replaced with air from nitrogen, then 0.2 g of triethylamine, 0.1 g of 4-methoxyphenol, 43.2 g of acrylic acid an...

Abstract

The colored photosensitive resin composition according to the present invention is characterized by comprising: a dye-containing colorant; and a compound represented by Chemical Formula 1.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter manufactured using the same, and an image display device. Background technique [0002] Color filters are widely used in imaging devices, image display devices such as liquid crystal display devices, and the like, and their application range is rapidly expanding. A color filter used in a color liquid crystal display device, an imaging element, etc. is generally manufactured by uniformly applying a colorant containing colorants corresponding to the respective colors of red, green, and cyan by spin coating on a substrate on which a black matrix pattern is formed. After coloring the photosensitive resin composition, it is heat-dried (hereinafter sometimes referred to as pre-firing), the formed coating film is exposed, developed, and further heat-cured as necessary (hereinafter also sometimes referred to as post-firing), This operation is repeated for each color to...
