DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide a double-sided pressure-sensitive adhesive tape which has good drop impact resistance in a low-temperature atmosphere when used for fixing a member of electronic equipment.SOLUTION: This double-sided pressure-sensitive adhesive tape 10 includes: a substrate 20; a first pressure-sensitive adhesive layer 30 provided on one surface of the substrate 20; and a second pressure-sensitive adhesive layer 40 provided on the other surface of the substrate 20. At least one of the first pressure-sensitive adhesive layer 30 and the second pressure-sensitive adhesive layer 40 includes an acrylic polymer and an acrylic oligomer whose weight-average molecular weight is 20,000 or less and whose monomer is different from that of the acrylic polymer. The content of a tackifier for providing tackiness is less than 5 mass%. By including the acrylic oligomer whose monomer is different from that of the acrylic polymer in at least one of the first pressure-sensitive adhesive layer 30 and the second pressure-sensitive adhesive layer 40, the drop impact resistance in a low-temperature atmosphere is improved.
