ELECTRICALLY PEELABLE ADHESIVE COMPOSITION, ELECTRICALLY PEELABLE ADHESIVE SHEET, AND METHOD FOR USING ELECTRICALLY PEELABLE ADHESIVE SHEET

摘要

This electrically peelable adhesive composition comprises: an emulsion-type acrylic adhesive (A) containing an acrylic polymer (A1) obtained by means of emulsion polymerization using a monomer mixture containing a (meth)acrylic alkyl ester in the presence of a surfactant; and a (poly)alkylene polyol (B) having a number average molecular weight of no greater than 2000. For every 100 parts by mass of the active ingredient of component (A), there are at least 3.5 parts by mass contained of component (B). The electrically peelable adhesive composition has a high adhesiveness before imposing a voltage, but by means of a short imposition of a voltage, the adhesive effect can decrease.
