EASY-DISASSEMBLY ADHESIVE COMPOSITION AND EASY-DISASSEMBLY ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide an easy-disassembly adhesive tape in which suitable attach to an adherend, and fixing between parts are possible, and dismantling is possible by heating and energy ray irradiation even if water of hot water or the like is not used at the dismantling time, and to provide an adhesive composition which can realize the easy-disassembly adhesive tape.SOLUTION: The pressure-sensitive adhesive composition includes: an acrylic polymer (X) consisting of a (meth)acrylate monomer as a main monomer component; and an acid catalyst or an acid generator, wherein the acrylic polymer (X) includes a poly (meth)acrylate chain (A) consisting of a repeating unit derived from a carboxyl precursor radical containing a (meth)acrylate monomer (a) in which the number of the repeating unit is at least 10.
