Abstract:
An electrically peelable pressure sensitive adhesive composition, which contains an acrylic polymer (A), a (poly)alkylene polyol (B) having a number average molecular weight of no greater than 2000, and an ammonium salt (C), has a high adhesiveness before voltage application, but the adhesiveness can decrease effectively by voltage application for a short time.
