Document Type and Number:
WIPO Patent Application WO/2015/152006
Kind Code:
A1
Abstract:
A side chain crystalline polymer according to the present invention comprises a crystalline macromonomer and a graft copolymer of a non-crystalline monomer. A thermosensitive adhesive agent according to the present invention contains an acrylic pressure-sensitive bonding agent and the side chain crystalline polymer and has decreased adhesive force at temperatures at or above the melting point of the side chain crystalline polymer. A thermosensitive adhesive sheet according to the present invention comprises the thermosensitive adhesive agent. A thermosensitive adhesive tape according to the present invention is provided with a substrate film and an adhesive agent layer that comprises the thermosensitive adhesive agent and that is laminated on at least one surface of the substrate film.
