Embodiment 1

[0195] Add 100 parts by mass of the following compound A as a curable compound, add 2 parts by mass of the following compound B as a photoinitiating compound in the photoinitiator, add 2 parts by mass of the following compound C as a visible light photosensitive compound, and add 2 parts by mass of the following compound C as a photoinitiator. Add 0.15 parts by mass of dibutyl hydroxytoluene (BHT) to the polymerization agent, add 10 parts by mass of silica (KE-C50HG manufactured by Nippon Shokubai Co., Ltd.) as an inorganic filler, add 15 parts by mass of resin filler as an organic filler ( F-351, manufactured by Aika Kogyo Co., Ltd.), 1 part by mass of a thixotropic agent (amorphous silica, TG-308F, manufactured by Cabot Japan Co., Ltd.), 10 parts by mass of EH-5001P (melting point: 100-120°C, manufactured by ADEKA Co., Ltd.), which is an adduct of amine compounds with a urea structure, was fully ground using a three-roll mill (C-43 / 4×10, manufactured by Inoue Seisakusho Co., ...

Embodiment 2

[0203] In the same manner as in Example 1, except that EH-5001P in Example 1 was changed to EH-4370S (adduct of an amine compound having a urea structure, melting point: 110 to 130°C, manufactured by ADEKA Corporation) The curable composition of Example 2 was obtained.

Embodiment 3、4

[0205] And the curable composition of embodiment 3, 4 is by changing the amount of thermosetting agent in embodiment 1, 2, makes the active hydrogen of thermosetting agent relative to the epoxy group of 1 equivalent curable compound be 1 equivalent And get. That is, except that the amounts of EH-5001P or EH-4370S in Examples 1 and 2 were changed as shown in Table 1, the curable compositions of Examples 3 and 4 were obtained in the same manner as in Examples 1 and 2. .

Abstract

The purpose of the present invention is to provide a curable composition that suppresses disorder in liquid crystal alignment and has excellent cleanability, a sealing agent for liquid crystals, a liquid-crystal panel in which alignment disorder is suppressed, and a method for producing the liquid-crystal panel. The curable composition according to the present invention contains a curable compound, a photoinitiator, a thermal curing agent, and a polymerization inhibitor. The curable compound includes a photocurable compound and a thermally curable compound. The thermal curing agent is an adduct of an amine compound having a urea structure.

Description

technical field [0001] The present invention relates to a curable composition, a sealing compound for liquid crystals, a liquid crystal panel, and a method for producing a liquid crystal panel. Background technique [0002] As one of the manufacturing methods of a liquid crystal panel, a liquid crystal dropping process is known. The liquid crystal dropping process is, for example, a method of coating a sealant on a substrate to form a frame, dropping liquid crystal into the frame, bonding opposing substrates, and curing the sealant to manufacture a liquid crystal panel. [0003] For example, Patent Document 1 discloses a sealant for a liquid crystal dropping process that is excellent in adhesiveness and moisture resistance reliability, and contains a curable resin, a filler having a different particle size, a thermosetting agent, and a radical polymerization initiator. Sealant for specific liquid crystal dropping process. According to Patent Document 1, due to the differen...
