Document Type and Number:
WIPO Patent Application WO/2023/032790
Kind Code:
A1
Abstract:
Provided is an adhesive sheet that has excellent flexibility at low temperatures and also has excellent resilience. According to the present invention, an adhesive sheet is formed from an adhesive composition [I] that contains an acrylic polymer (A). The acrylic polymer (A) includes a structural moiety derived from a compound (a1) represented by formula (1) and a structural moiety derived from a hydroxy group–containing (meth)acrylate (a2), and the storage shear modulus (G') of the adhesive sheet at -40°C is no more than 1200 kPa. (1) CH2=CH(R1)-COO(R2) (in which R1 represents a hydrogen atom or a methyl group, and R2 represents a C5–20 straight-chain or branched alkyl group).
