摘要： Provided is a heat-expandable removable acrylic pressure-sensitive adhesive tape that has high normal-state adhesive power when bonded independently of whether the adherend has or does not have irregular surface and permits easy separation when the bonded region is separated and disassembled by lowering the adhesive power by heating, that permits easily separation-decomposition, even after long-term storage at high temperature. The heat-expandable removable acrylic pressure-sensitive adhesive tape or sheet according to the present invention includes at least a heat expanding agent-containing pressure-sensitive adhesive layer, and the tape or sheet has an initial 90°peel adhesive strength to a polycarbonate plate as adherend of 10 N/25 mm or more and a 90°peel adhesive strength after storage in an atmosphere at 80°C for 2 months as bonded to the polycarbonate adherend and after heat expansion treatment of less than 10 N/25 mm.

摘要： A pressure sensitive adhesive label having an information indicating part on one side of a base and a pressure sensitive adhesive layer on the other side and attached to the outer surface of the housing of a hard disc drive in order to reduce generation of sound at the time of driving the hard disc drive. Both the function of indicating various items of information and the function of reducing generation of sound at the time of driving a hard disc drive can be performed by the pressure sensitive adhesive label for hard disc drive. A method for reducing generation of sound at the time of driving a hard disc drive using the pressure sensitive adhesive label can also be provided.
