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

摘要

PROBLEM TO BE SOLVED: To provide an electrically peelable adhesive composition which has high adhesive force before voltage application and can effectively reduce adhesive force by voltage application for a short time, and to provide an electrically peelable adhesive sheet having an adhesive layer formed of a material containing the adhesive composition and a method for using the electrically peelable adhesive sheet.SOLUTION: There is provided an electrically peelable adhesive composition which is composed of an emulsion type acrylic adhesive containing an emulsion type acrylic polymer (A1) obtained by emulsion polymerization of a monomer mixture containing a (meth)acrylic acid alkyl ester in the presence of a surfactant and a (poly)alkylene polyol (B) having a hydroxyl value of 70 to 1500 mgKOH/g, where the content of the (B) component is 3.5 pts.mass or more based on 100 pts.mass of an active ingredient of the (A) component.
