Electrically peelable adhesive composition, electrically peelable adhesive product, and utilization thereof

An electrically peelable adhesive composition comprising an acrylic polymer, an ionic liquid and an alkyl ether of a polyethylene glycol, wherein a content of the ionic liquid is more than 30 parts by weight and 90 parts by weight or less relative to 100 parts by weight of the acrylic polymer and a content of the alkyl ether of the polyethylene glycol is 5 parts by weight to 45 parts by weight relative to 100 parts by weight of the acrylic polymer, wherein:

• (i) the acrylic polymer is a copolymer derived from 90% to 99% by weight of an alkyl (meth) acrylate having an alkyl group with 1 to 4 carbon atoms, and 1% to 10% by weight of a combination of a carboxyl group-containing monomer and a hydroxy group-containing monomer, (ii) the carboxyl group-containing monomer is acrylic acid or methacrylic acid, (iii) the hydroxy group-containing monomer is 2-hydroxyethyl (meth) acrylate, (iv) the ionic liquid is a combination of a cation selected from imidazolium cations and an anion selected from (FSO2)2N−, (CF3SO2)2N− and BF4−, and (v) the alkyl ether of the polyethylene glycol is dimethyl tetraglycol, diethylene glycol dibutyl ether or triethylene glycol butyl methyl ether.
