Abstract
A pressure-sensitive adhesive sheet according to an embodiment of the present invention has a pressure-sensitive adhesive layer including an acrylic polymer. This acrylic polymer contains, as monomer components, an acrylic monomer not containing a polar group (A) and a polar group-containing monomer (B). The 100% modulus of this pressure-sensitive adhesive layer is 20 to 200 N/cm2.
Claims20
A pressure-sensitive adhesive sheet comprising a pressure-sensitive adhesive layer including an acrylic polymer, wherein
