[0176] NC-3000H (manufactured by Nippon Kayaku Co., Ltd., epoxy equivalent 288 g / eq) and XD-1000 (manufactured by Nippon Kayaku Co., Ltd., epoxy equivalent 254 g) were added as epoxy resin (a) in the amount described in Table 1 / eq), EOCN-103S (manufactured by Nippon Kayaku Co., Ltd., epoxy equivalent 200g / eq), and acrylic acid (AA for short, Mw=72) as compound (b) was added in the amount recorded in Table 1. Dimethylolpropionic acid (DMPA for short, Mw=134) was added as the compound (c) in the amount described in . 3 g of triphenylphosphine was added as a catalyst, and propylene glycol monomethyl ether monoacetate was added as a solvent so that the solid content became 80% by mass of the reaction liquid. React at 100° C. for 24 hours to obtain a reactive epoxy carboxylate compound (G) solution. The next reaction was performed with a solid content acid value (AV: mgKOH / g) of 5 o...

Abstract

The invention relates to an active energy ray-cured resin compound, and a coloring partition and a black matrix for a display element. The coloring partition and / or the black matrix for the display element is excellent in voltage holding ratio and sealing performance. The active energy ray-cured resin compound for the coloring partition or the black matrix for the display element contains (A) reactive polycarboxylic compound, (B) reactive compounds, (C) a photopolymerization initiator, (D) black pigment, (E) dispersant and (F) organic solution, wherein the reactive polycarboxylic compound(A) is obtained trough reaction between a reaction product of epikote (a) with at least two epoxy groupsin one molecule, a compound(b) with more than one polymerizable olefinic unsaturated groups and more than one carboxyls and a compound with at least two hydroxys and more than one carboxyl, and itaconic anhydride and / or citraconic anhydride as polybasic anhydride (d).

Description

technical field [0001] The present invention relates to an active energy ray curable resin composition, a colored spacer for display elements, and a black matrix. Background technique [0002] In the material for a display device, a resin composition containing a binder polymer, a photopolymerizable monomer, a photopolymerization initiator, and the like is used. In recent years, as materials for display devices (LCD, EL, PDP, FED (SED), rear projection displays, electronic paper or digital cameras, etc., especially display elements, display element peripheral materials), such as color liquid crystal display Devices (LCDs) are rapidly gaining popularity. Generally speaking, the structure of a color liquid crystal display device is: a color filter is opposed to an electrode substrate such as a TFT substrate, and a gap of about 1 μm to about 10 μm is provided, and a liquid crystal compound is filled in the gap, and the surrounding area is sealed with a sealant. The material i...
