Document Type and Number:
WIPO Patent Application WO/2020/235460
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an adhesive sheet having excellent step followability and durability and having low water vapor permeability. The present invention relates to an adhesive sheet which is formed by heating and drying an adhesive composition containing a solvent and an olefin-based polymer, wherein the gel fraction of the adhesive sheet is less than 2%, the adhesive sheet has active energy ray curability, and the adhesive sheet has a relative permittivity, at 23 °C and 1 MHz, of less than 2.8 after being irradiated with active energy rays under the condition that an integrated light amount reaches 1500 mJ/cm2.
