<p><P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet having good flexibility. <P>SOLUTION: The pressure-sensitive adhesive sheet includes a substrate layer including a film which contains at least a urethane polymer, and a pressure-sensitive adhesive layer disposed on at least one side of the substrate layer, in which the pressure-sensitive adhesive sheet has residual stress of 23 N/cm or lower after having been held in a 10% elongated state for 60 seconds. Preferably, the pressure-sensitive adhesive sheet has a 100% modulus of 8 N/cm or higher. The film constituting the substrate layer is preferably a composite film containing a (meth)acryl polymer and a urethane polymer. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
