Embodiment 1

[0121]Kraton G-1652 (manufactured by Japan Kraton Polymer, hydrogenated product of styrene-butadiene-styrene block copolymer: SEBS, mass average molecular weight 79,000, styrene content 30%, hydrogenation rate 90% 20 parts by mass of the above) were adjusted so that the solid content would be 20 mass % in toluene, stirred and dissolved. Then, 65 parts by mass of I-MARVP100 (manufactured by Idemitsu Kosho Co., Ltd., dicyclopentadiene / aromatic copolymer hydrogenated petroleum resin) as a hydrogenated cyclic olefin compound, and Parleam 24 (manufactured by NOF, hydrogenated polybutylene resin) as a softener were added. Alkene, number average molecular weight 1350) 15 mass parts, then adjust toluene so that it becomes 30 mass % of solid content, mix and stir to a homogeneous state, and obtain a resin mixed solution.

[0122] The resin mixed solution obtained above was applied to the release surface of a release-treated polyester film (manufactured by Teijin DupontFilm Co., Ltd., P...

Abstract

This resin composition for encapsulation of elements for organic electronic devices is transparent, has excellent flexibility, steam barrier properties and adhesive force, and can suppress the occurrence of dark spots; also provided are a resin sheet for encapsulation of elements for organic electronic devices, an organic electroluminescence element, and an image display device. This adhesive resin composition is used to encapsulate elements for organic electronic devices, and is characterized by containing a diene polymer and a softening agent, wherein the content of the softening agent is 5-30 mass% of the total mass.

Description

technical field [0001] The present invention relates to a resin composition for element sealing of an organic electronic device, a resin sheet for element sealing of an organic electronic device, an organic electroluminescence element, and an image display device, which are used when sealing an element for an organic electronic device. Background technique [0002] In recent years, research on various organic electronic devices such as organic electroluminescent (hereinafter also referred to as "organic EL") displays, organic EL lighting, organic semiconductors, and organic solar cells is being actively carried out, and it is expected to replace liquid crystal displays ( LiquidCrystalDisplay, LCD) as a next-generation display, or replace light-emitting diode (LightEmittingDiode, LED) lighting as a next-generation lighting. Furthermore, since all the constituent elements can be formed of solid materials, the organic EL element has the possibility of being used as a flexible d...
