Title:
DOUBLE-SIDED PRESSURE-SENSITIVE ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2017/073722
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a double-sided pressure-sensitive adhesive tape which can exhibit high high-temperature adhesiveness and which, even when stress is applied thereto at high temperatures of 80ºC and higher, is less apt to peel off.
The double-sided pressure-sensitive adhesive tape of the present invention comprises a pressure-sensitive adhesive layer comprising: a polymer component that comprises a crosslinkable-functional-group-containing acrylic polymer obtained by living radical polymerization and having a weight-average molecular weight of 500,000-1,500,000 and a molecular-weight distribution (Mw/Mn) of 1.05-2.5; a crosslinkable-functional-group-containing rosin-based tackifier resin or a crosslinkable-functional-group-containing terpene-based tackifier resin; and a crosslinking agent. When a 200g shearing load is applied at 80ºC for three minutes to the double-sided pressure-sensitive adhesive tape applied so as to have an adhesion area of 1 cm2, the degree of shear deformation is 100-300%.
