manufacture example 1

[0177] Production Example 1. Production of Dispersion Resin A1

[0178] 277 g of methoxybutyl acetate was injected|thrown-in to the separation-type flask of internal volume 1L equipped with the stirrer, thermometer, reflux condenser, dropping funnel, and nitrogen introduction tube, and it heated to 80 degreeC. Next, prepare 3,4-epoxytricyclo[5.2.1.0,2,6]decane-9-yl acrylate and 3,4-epoxytricyclo[5.2.1.0,2,6] A mixture obtained by dissolving 301 g of decan-8-yl acrylate in a molar ratio of 50:50, 49 g of methacrylic acid, and 23 g of azobisdimethylvaleronitrile in 350 g of methoxybutyl acetate mixture. The said mixed solution was dripped in the flask over 5 hours using the dropping funnel, and it reacted for 3 hours, and dispersion resin A1 [solid content (NV) 35.0 weight%] was manufactured. The acid value (dry) of the dispersed resin A1 produced above was 69.8 KOH mg / g, the weight average molecular weight (Mw) was 12,300, and the degree of dispersion (Mw / Mn) was 2.1.

[0179] Production Example 2. Production of Dispersion Resin A2

[0180] Prepare a flask equipped with a stirrer, thermometer, reflux condenser, dropping funnel, and nitrogen inlet. As a monomer dropping funnel, 14.4 parts by weight (0.2 moles) of acrylic acid, 140.8 parts by weight (0.8 moles) of benzyl methacrylate, 2.0 parts by weight of tert-butyl peroxy-2-ethylhexanoate, propylene glycol monomethyl 40.0 parts by weight of ether acetate (PGMEA) were mixed and prepared. As a chain transfer agent dropping tank, 3.0 parts by weight of n-dodecanemercaptan and 24.0 parts by weight of PGMEA were mixed and prepared. After that, 395 parts by weight of PGMEA was added to 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. The dropwise addition was performed for 4 hours each while maintai...

Abstract

The invention provides a colored photosensitive resin composition, a pattern layer manufactured by using the colored photosensitive resin composition, a color filter including the pattern layer, and adisplay device including the color filter. The colored photosensitive resin composition comprises a colored dispersion liquid, an alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator and a solvent. The colored dispersion liquid comprises a colorant containing an organic black pigment, a blue pigment, a purple pigment and carbon black, a dispersion resin containinga copolymer of the following chemical formula 1, and a solvent, wherein in the chemical formula 1, R1 and R2 are each independently hydrogen or a methyl group, and the molar ratio of a monomer a to amonomer b is 1: 20 to 20: 1.

Description

technical field [0001] The present invention relates to a colored dispersion liquid, a colored photosensitive resin composition containing the above colored dispersion liquid, a pattern layer produced using the above resin composition, a color filter containing the above pattern layer, and a display device containing the above color filter. Background technique [0002] Color filters are widely used in various display devices such as imaging elements and liquid crystal displays (LCDs), and the range of applications thereof is rapidly expanding. The above-mentioned color filters used in imaging elements, liquid crystal display devices, etc. are formed of coloring patterns of three colors of red (Red), green (Green) and blue (Blue), or are formed of yellow (Yellow), magenta ( Magenta) and blue-green (Cyan) coloring patterns are formed. [0003] Each colored pattern of the above-mentioned color filter is generally formed using a colored photosensitive resin composition contain...
