ENERGY RAY-PEELABLE ADHESIVE COMPOSITION, AND ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide an energy ray-peelable adhesive composition, whose initial adhesion to an adherend is high, whose adhesion is difficult to degrade even if the composition is exposed to high temperature, and that has an adhesion required for fixation and protection and can be peeled very easily when peeled even after exposed to the high temperature.SOLUTION: An energy ray-peelable adhesive composition 2 comprises: an acrylic polymer containing a copolymer which uses acrylonitrile as a monomer component; an energy ray-polymerizable compound; a thioxanthone-based polymerization initiator; and a crosslinking agent. The adhesive composition has an adsorption peak in a wavelength range of 330 to 410 nm.
