Electrically peelable adhesive composition and electrically peelable adhesive sheet, and method for using electrically peelable adhesive sheet

摘要

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.
