Patent ID: 10081741

Abstract:
The present invention provides: an adhesive composition comprising a diene-based rubber (A) that includes a radiation-curable functional group, a cured adhesive layer having a thickness of 60 μm that is formed by curing the adhesive composition having a water vapor transmission rate at a temperature of 40° C. and a relative humidity of 90% of 30 g/(m2·day) or less; an adhesive sheet comprising a curable adhesive layer that is formed using the adhesive composition; and an electronic device comprising a sealing material, the sealing material being formed using the adhesive composition. According to the present invention, provided are: an adhesive composition that is useful as a material for forming an adhesive layer that exhibits an excellent water barrier capability and sufficient cohesive strength, and exhibits adhesion and holding power in a well-balanced manner, an adhesive sheet that includes an adhesive layer that is formed using the adhesive composition, and an electronic device that includes a sealing material that is formed using the adhesive composition.
