Problems solved by technology

[0002] In recent years, light-emitting devices have been prepared by mounting light-emitting diode (LED) elements on substrates using anisotropic conductive paste or anisotropic conductive film, but in the case of operating the light-emitting device, the anisotropy used for mounting The insulating adhesive component in the conductive paste or the anisotropic conductive film changes color due to heat or light, and there is a problem that the emitted light of the LED element changes color due to the color change.

Embodiment 1

[0041] In a nitrogen stream, drop 28.37g (100.88mmol) of 1-allyl-3,5-diglycidyl isocyanurate (MADGIC, Shikoku Chemical Industry Co., Ltd.) and 6.63 g (20.17 mmol) of tetrakis(hydrogenated dimethylsiloxy) silane (SIT7273.0, Gelest Inc.), the mixture was stirred at 80° C. until uniformly melted. Next, 30.2 μL of a 2% Karstedt catalyst solution (xylene solution) was added to the molten mixture, heated to 120° C. while stirring, and after the temperature of the molten mixture reached 120° C., the temperature was maintained for 9 hours. 1-allyl-3,5-diglycidyl isocyanurate and tetrakis(hydrodimethylsiloxy)silane were reacted.

[0042] After completion of the reaction, the reaction mixture was cooled, and unreacted monomers were distilled off under reduced pressure (150° C. / 0.1 kPa) to obtain an epoxy group-containing siloxane compound of formula (1a).

Abstract

This novel epoxy group-containing siloxane is represented by formula (1). The substituents R independently represent an alkyl group or a phenyl group. The linking groups A independently represent a divalent hydrocarbon group. The substituents R1 and R2 independently represent an epoxy group-containing organic group, an alkyl group, or an aryl group, but at least one of R1 and R2 represents an epoxy group-containing organic group.

Description

technical field [0001] The present invention relates to a novel epoxy group-containing siloxane compound useful as an adhesive component of an anisotropic conductive adhesive used for anisotropically conductively connecting a light-emitting element to a wiring board. Background technique [0002] In recent years, light-emitting devices have been prepared by mounting light-emitting diode (LED) elements on substrates using anisotropic conductive paste or anisotropic conductive film, but in the case of operating the light-emitting device, the anisotropy used for mounting The conductive paste or the insulating adhesive component in the anisotropic conductive film is discolored by heat or light, and there is a problem that the emitted light of the LED element changes color according to the discoloration. [0003] Therefore, it has been proposed to use an epoxy group-containing organosilicon compound that provides a cured product excellent in heat resistance and light resistance a...
