Synthetic example 1

[0141] Add 30 g of methanol to 2 g of dodecylpyridinium chloride, and slowly drop in 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 was dried in a vacuum oven at 50° C. for 12 hours to obtain 8.5 g of the following Chemical Formula A-1. (Synthesis with reference to Eur.J.Inorg.Chem.2014, 21-35.)

[0142] [Chemical formula A-1]

[0143]

Synthetic example 2

[0145] 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.

[0146] [Chemical formula A-2]

[0147]

Synthetic example 3

[0148] Synthesis Example 3: Synthesis of Alkali-Soluble Resin B

[0149] 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-dodecyl mercaptan. Then, the temperature of the reaction liquid was raised to 80° C. while stirring, and the reaction was carried out for 4 hours.

[0150] 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 acry...

Abstract

The present invention relates to a colored photosensitive resin composition, a color filter, and an image display device having the color filter. More specifically, it is characterized in that it contains a compound represented by the following chemical formula 1, [chemical formula 1] (X + ) n (Y) m‑ By containing the compound represented by the specific chemical formula, the above-mentioned colored photosensitive resin composition exhibits high reliability and high contrast characteristics without reducing the brightness when applied to a color filter and an image display device having a color filter. A color filter produced from the above-mentioned colored photosensitive resin composition and an image display device including the color filter have an effect of being excellent in sensitivity.

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, and the like, and their application range is rapidly expanding. Color filters used in color liquid crystal display devices, imaging elements, etc. are generally produced by uniformly applying coloring materials corresponding to the respective colors (red, green, and cyan) by spin coating on a substrate with a black matrix pattern formed thereon. After coloring the photosensitive resin composition with an additive, it is heat-dried (hereinafter sometimes referred to as pre-firing), and 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 form pixels of each co...
