Example Embodiment

[0160] Synthesis example 1

[0161] Add 30 g of methanol to 2 g of Dodecylpyridinium chloride, and slowly drop it into the completely dissolved solution to dissolve 6 g of Phosphotungstic acid hydrate (Aldrich, P4006) in A solution in 25g of water. After dripping, after stirring at 25-50°C for 4 hours, 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. (Refer to Eur.J.Inorg.Chem.2014, 21-35 synthesis.)

Example Embodiment

[0164] Synthesis Example 2

[0165] In place of Dodecylpyridinium chloride, Tetrapropylammonium Hydroxide (TCI, product number T0171) was used instead of Dodecylpyridinium chloride, and 7.3 g of Chemical Formula A-2 was obtained by the same method as in Synthesis Example 1.

Example Embodiment

[0168] Synthesis example 3: Synthesis of binder resin (B)

[0169] Put 100g of propylene glycol monomethyl ether acetate and 100g of propylene glycol monomethyl ether into a flask equipped with a stirrer, thermometer, reflux condenser, dropping funnel, and nitrogen introduction tube, and change the atmosphere in the flask from air to nitrogen. , Put 8.2 g of azobisisobutyronitrile, 3.1 g of monomethacrylate (Hitachi Chemical Co., Ltd. FA-513M) with tricyclodecane skeleton, 55.2 g of 2-ethylhexyl acrylate, 4-methyl 5.9 g of styrene, 85.2 g of glycidyl methacrylate, 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] After lowering the temperature of the reaction solution to normal temperature and replacing the atmosphere in the flask from nitrogen to air, 0.2 g of triethylamine, 0.1 g of 4-methoxyphenol, 43.2 g of acrylic acid, and propylene glycol monomethyl were added fro...

Abstract

The colored photosensitive resin composition according to the present invention comprises: a colorant comprising a dye; and a compound represented by the 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...
