Embodiment 1～17、 comparative example 1

[0201] According to the mixing ratio recorded in Tables 1 and 2, a planetary mixer (manufactured by Thinky Co., Ltd., "あわとり Taro") After mixing each material, the sealing compound for liquid crystal display elements of Examples 1-17 and Comparative Example 1 was prepared by mixing using a three-roll machine further.

[0202]

[0203] The following evaluation was performed about each sealing compound for liquid crystal display elements obtained by the Example and the comparative example. The results are shown in Tables 1 and 2.

[0204] (photocurable)

[0205] Each of the sealants for liquid crystal display elements obtained in Examples and Comparative Examples was coated on a glass substrate so that the gap after bonding the glass substrates was about 5 μm, and a glass substrate of the same size was stacked on the substrate, and then, using Metal halide lamp irradiation 100mW / cm 2 Ultraviolet light (wavelength 365nm) for 10 seconds. Photocurability was evaluated by meas...

Abstract

A purpose of the present invention is to provide a polymerizable monomer having low contamination with respect to liquid crystals, high sensitivity to light of long wavelengths, and an exceptional sensitizing effect, and a polymer compound obtained by polymerizing the polymerizable monomer. Another purpose of the present invention is to provide a photocurable resin composition containing the polymerizable monomer and / or the polymer compound; a sealing agent for liquid crystal display elements which uses the photocurable resin composition; and a vertical conduction material and liquid crystal display element which are manufactured using the sealing agent for liquid crystal display elements. The present invention is a polymerizable monomer obtained by causing a thioxanthone derivative that has a functional group capable of reacting with a dialkylaminobenzoic acid compound or epoxy group to react with an epoxy group having an unsaturated double bond or an epoxy group having an alkoxysilyl group.

Description

technical field [0001] The present invention relates to a polymerizable monomer that has low contamination of liquid crystals, high sensitivity to long-wavelength light, and excellent sensitization effect, and a polymer compound obtained by polymerizing the polymerizable monomer. Also, the present invention relates to a photocurable resin composition containing the polymerizable monomer and / or the polymer compound, a sealant for a liquid crystal display element produced using the photocurable resin composition, and a liquid crystal display device using the photocurable resin composition. The upper and lower conduction materials and liquid crystal display elements manufactured by the element sealant. Background technique [0002] In recent years, as a method of manufacturing liquid crystal display elements such as liquid crystal display units, from the viewpoints of shortening takt time and optimizing the amount of liquid crystals used, the method disclosed in Patent Document...
