[0202] Preparation Example 2-1: Zn-1

[0203] 18g 2,4-dihydroxybenzaldehyde, 11.96g Zn(OAc) 2 and 72 g of methanol were placed in a 4-neck flask equipped with a condenser, dropping funnel, thermometer and stirrer, and nitrogen replacement was performed. After nitrogen replacement, the temperature was raised to 60°C, and 3.92 g of ethane-1,2-diamine dissolved in 18 g of methanol was added dropwise over 30 minutes, followed by stirring for 2 hours. After the reaction was completed, it was cooled to room temperature, followed by filtration and drying, thereby providing a compound of Zn-1.

Abstract

The invention relates to a colored photosensitive resin composition, a color filter, and a liquid crystal display device having the color filter. The composition comprises a coloring agent (A), an alkali-soluble resin (B), a photopolymerizable compound (C), a photopolymerization initiator (D), a solvent (E) and an additive (F), wherein the coloring agent (A) comprises one or more pigment (a1) or one or more dye (a2); the additive (F) comprises a compound of a formula (I); and the alkali-soluble resin (B) comprises a copolymer of a monomer of a formula (VI), a monomer of a formula (VII) and other monomers capable of polymerization with the monomers. The invention also provides the color filter formed by using the compound, and the liquid crystal display device having the color filter. The composition has good storage stability, can form color filter patterns with high resolution and can provide rapid development.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter, and a liquid crystal display device having the color filter. Specifically, the present invention provides a colored photosensitive resin composition capable of forming a high-resolution color filter pattern, a color filter formed using the composition, and a liquid crystal display device having the color filter , has good storage stability and can achieve rapid development. Background technique [0002] Color filters have been widely used in imaging devices and liquid crystal displays (LCDs), and their applications are expanding. Color filters are conventionally produced by uniformly coating a colored photosensitive resin composition containing a red, green or blue pigment on a black matrix substrate on which a black pattern is formed, followed by heating and drying, so that the obtained color filter is dried. The coating film is exposed to light and develope...
