Patent ID: 11535777

Abstract:
To provide a double-sided pressure-sensitive adhesive sheet having high flexing resistance that does not suffer flexure and exfoliation in a flexing test that is closer to the actual use environment. A double-sided pressure-sensitive adhesive sheet having no substrate, containing a pressure-sensitive adhesive composition containing a (meth)acrylate ester (co)polymer (A), and having a glass transition temperature (Tg) defined by a Tan δ peak temperature of dynamic viscoelasticity in a range of −50° C. to −20° C., a storage elastic modulus G′ at a frequency of 1 Hz and a temperature 100° C. in a range of 2.0×103 to 3.0×104 Pa, and a thickness of 10 μm or more and 150 μm or less.
