manufacture example 1

[0203] Sodium hydride (comprising 55% by weight of mineral oil) (15.4 g, 352.9 mmol) and DMSO (510.6 g) were added to a 2 L four-necked flask equipped with a condenser, a stirrer and a thermometer, and after cooling to 0° C., A solution obtained by dissolving o-phenylphenol (50.6 g, 297.3 mmol) in DMSO (191.0 g) was added dropwise thereto. Thereafter, it was placed in a 60° C. oil bath, and a solution obtained by dissolving 2-chloroethyl vinyl ether (38.2 g, 358.5 mmol) in DMSO (61.4 g) was added dropwise. After stirring the reaction liquid for 6 hours, after cooling to 0 degreeC, water was slowly dripped and quenched, and it transferred to the separatory funnel. The aqueous layer was extracted with ethyl acetate, and saturated brine was added to the organic layer for washing. Thereafter, the organic layer was separated and dehydrated with anhydrous sodium sulfate, and then the solvent was distilled off to obtain a liquid crude product. This was purified by silica gel column...

[0208] Put MPV (82 parts by weight), VCZ (17 parts by weight) and photocationic polymerization initiator (1 part by weight) into the rotation and revolution type stirring and defoaming device (model: AR-250, made by Thinky) and stir to obtain the resin Composition (1).

[0209] The obtained resin composition (1) was cast in a mould, and irradiated with ultraviolet light (irradiation dose: 1500mJ / cm2) from a distance of 10cm with a high-pressure mercury lamp of 200W / cm 2 ).

[0210] The viscosity of the obtained resin composition (1) was measured before ultraviolet irradiation, immediately after ultraviolet irradiation, and 30 minutes after ultraviolet irradiation, and the degree of viscosity increase after ultraviolet irradiation was calculated from the following formula.

[0211] Viscosity increase after UV irradiation = Viscosity 30 minutes after UV irradiation / Viscosity immediately after UV irradiation

Abstract

The present invention provides a resin composition that can be used as a filler when sealing an organic EL element by a dam-fill sealing construction method, wherein the resin composition is excellent in applicability and acetone solubility, and can be arbitrarily set thickening and The timing of curing can form a cured product with high refractive index, low moisture permeability and low outgassing. The resin composition of the present invention contains at least one compound (A) represented by the following formula (a), a compound represented by the following formula (b-1) and a compound represented by the following formula (b-2) compound (B), and photocationic polymerization initiator (C).

Description

technical field [0001] The present invention relates to a resin composition that can be used as a filling material when sealing an organic electroluminescence element by a dam-fill sealing construction method. This application claims priority based on Japanese Patent Application No. 2016-074517 for which it applied in Japan on April 1, 2016, and uses the content here. Background technique [0002] From the perspective of impact resistance, high visual recognition and diversity of luminous colors, organic EL devices including organic electroluminescent (hereinafter also referred to as "organic EL") elements are used as full-color flat panel displays or as substitutes for LEDs. And highly anticipated. According to the different ways of light export, organic EL devices include top emission type and bottom emission type. [0003] However, organic EL elements are more easily affected by moisture than other electronic components, and there is a problem that the oxidation of elec...
