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

摘要

An electrically peelable pressure sensitive adhesive sheet has a pressure sensitive adhesive layer formed of an electrically peelable pressure sensitive adhesive composition comprising an acrylic copolymer (A) comprising 1 to 99 mass% of a constituent unit (a1) derived from a compound represented by the following general formula (a1), and a surfactant (B). The electrically peelable pressure sensitive adhesive sheet has high adhesion before voltage application, but the adhesion can be effectively decreased by voltage application for a short time.
wherein R 1 represents a hydrogen atom or a methyl group, R 2 represents an alkylene group having 1 to 5 carbon atoms that is unsubstituted or has a substituent, and R 3 represents an alkyl group having 1 to 8 carbon atoms that is unsubstituted or has a substituent; and a value of n is an integer of 1 or more.
