More Information
Summary:Provided is a pressure-sensitive adhesive sheet formed of at least two layers, including a rubber-based pressure-sensitive adhesive layer (A) and an acrylic pressure-sensitive adhesive layer (B) that are directly laminated, in which the pressure-sensitive adhesive sheet has a large interlayer peel strength. The pressure-sensitive adhesive sheet is a pressure-sensitive adhesive sheet formed of at least two layers, including a rubber-based pressure-sensitive adhesive layer (A) and an acrylic pressure-sensitive adhesive layer (B) that are directly laminated, in which the pressure-sensitive adhesive sheet has an interlayer peel strength upon peeling of the acrylic pressure-sensitive adhesive layer (B) from the rubber-based pressure-sensitive adhesive layer (A) under conditions of a measurement temperature of 23°C, a tension speed of 0.3 m/min, and a peel angle of 180°C of 2.0 N/20 mm or more.
