Double-Sided Pressure-Sensitive Adhesive Tape

Abstract DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE TAPE 5 Provided is a double-sided pressure-sensitive adhesive tape to be used for re-peeling an adherend having a low polar surface from an adherend having a polar surface after bonding the adherend having a low polar surface to the adherend having a polar surface, in which a laminate of the double-sided pressure 0 sensitive adhesive tape and the adherend having a low polar surface can be easily peeled in an integrated manner from the adherend having a polar surface, and an adhesive residue on the surface of the adherend having a polar surface can be suppressed. A double-sided pressure-sensitive adhesive tape of the 5 present invention includes a first pressure-sensitive adhesive layer, a base material, and a second pressure-sensitive adhesive layer in the stated order, in which the second pressure-sensitive adhesive layer has a pressure-sensitive adhesive strength with respect to a SUS304 steel plate, which is larger than a pressure 0 sensitive adhesive strength of the first pressure-sensitive adhesive layer with respect to the SUS304 steel plate, in which the pressure-sensitive adhesive strength of the first pressure sensitive adhesive layer with respect to the SUS304 steel plate is from 0.5 N/20 mm to 5 N/20 mm, and in which the pressure 25 sensitive adhesive strength of the second pressure-sensitive adhesive layer with respect to the SUS304 steel plate and the pressure-sensitive adhesive strength of the first pressure sensitive adhesive layer with respect to the SUS304 steel plate have a difference of from 3 N/20 mm to 20 N/20 mm.
