RESIN COMPOSITION FOR ELEMENT ENCAPSULATION FOR ORGANIC ELECTRONIC DEVICES, RESIN SHEET FOR ELEMENT ENCAPSULATION FOR ORGANIC ELECTRONIC DEVICES, ORGANIC ELECTROLUMINESCENT ELEMENT AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/156593
Kind Code:
A1
Abstract:
Provided are: a resin composition for element encapsulation for organic electronic devices, which captures not only the moisture on the front surface and lateral surface of the resin composition for element encapsulation for organic electronic devices but also the moisture permeating through the inside of the resin composition for element encapsulation for organic electronic devices, and which thus exhibits excellent long-term reliability and excellent visibility; a resin sheet for element encapsulation for organic electronic devices; an element for organic electronic devices, which is encapsulated by this resin composition for element encapsulation for organic electronic devices; and an image display device. This resin composition for element encapsulation for organic electronic devices is characterized by being mainly composed of a polyisobutylene resin (A) that contains a polyisobutylene skeleton in the main chain or in a side chain and has a weight average molecular weight (Mw) of 300,000 or more and a tackifier (B), while containing an organic metal compound (C) that has hygroscopic properties. This resin composition for element encapsulation for organic electronic devices is also characterized by having a moisture content of 1,000 ppm or less.
