ADHESIVE AGENT COMPOSITION, ADHESIVE SHEET, AND ELECTRONIC DEVICE

摘要

The present invention provides: an adhesive agent composition which includes a diene-based rubber (A) having a radiation-curable functional group, and which can be subjected to a curing reaction to form a cured adhesive-agent layer having a thickness of 60 µm and exhibiting a water vapour transmission rate under an atmosphere of 90% relative humidity at a temperature of 40˚C of not more than 30g/(m2∙day); an adhesive sheet provided with the adhesive-agent layer formed using the adhesive agent composition; and an electronic device provided with a sealant formed using the adhesive agent composition. According to the present invention, provided are: an adhesive agent composition useful as a formation material for an adhesive-agent layer exhibiting excellent moisture barrier properties and an excellent balance between adhesive strength and holding power; an adhesive sheet provided with the adhesive-agent layer formed using the adhesive agent composition; and an electronic device provided with a sealant formed using the adhesive agent composition.
