Document Type and Number:
WIPO Patent Application WO/2015/068746
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive tape that is difficult to peel off even when the adhesive tape is thin and is capable of actualizing a high constant load release property on low-polarity adherends such as polypropylene (PP) and the like. The present invention is an adhesive tape having an adhesive layer that contains: a polymer component containing 60 wt% or more of an acrylic polymer containing hydroxyl groups and/or carboxyl groups having a weight-average molecular weight of 300,000-2,000,000 and a molecular weight distribution (Mw/Mn) of 1.05-2.5 obtained by living radical polymerization; a rosin-based tackifier resin having a hydroxyl group and/or carboxyl group or a terpene-based tackifier resin having a hydroxyl group and/or carboxyl group; and a crosslinking agent.
