Document Type and Number:
Japanese Patent JP6757479
Kind Code:
B2
Abstract:
A pressure sensitive adhesive sheet (11) according to the present invention contains an acryl-based base polymer having a crosslinked structure, and an acryl-based oligomer having a glass transition temperature of 60° C. or higher. The pressure sensitive adhesive sheet has a storage elastic modulus G′25 of 5 to 75 kPa at 25° C. and 1 Hz, a loss tangent tan δ25 of 0.2 to 0.45 at 25° C. and 1 Hz, a loss tangent tan δ100 of 0.2 to 0.45 at 100° C. and 1 Hz, a difference between the tan 625 and the tan δ100 of −0.09 to 0.09, and a glass transition temperature of −15° C. or lower.
