Abstract: A double-sided tape including: a first adhesive layer including about 100 parts by weight of an acrylic polymer, about 1 to about 2 parts by weight of a silane coupling agent, and about 0.1 to about 0.18 parts by weight of carbon black; a foamed polymer layer disposed on the first adhesive layer, including a urethane foam; an interlayer polymer layer disposed on the foamed polymer layer, including a polyolefin (PO), polyethylene terephthalate (PET), a polyester, or a combination thereof; and a second adhesive layer disposed on the interlayer polymer layer, including about 100 parts by weight of an acrylic polymer, about 1 to about 2 parts by weight of a silane coupling agent, and about 0.1 to about 0.18 parts by weight of carbon black, wherein an overall thickness of the double-sided tape is in a range of about 0.4 millimeters to about 1.3 millimeters.

Abstract: The present invention aims to provide an adhesive capable of exhibiting excellent adhesive force while having a high bio-derived carbon content, an adhesive tape containing the adhesive, and a method for fixing an electronic device component or an in-vehicle component. Provided is an adhesive containing a (meth)acrylic copolymer that contains 48% by weight or more of structural units derived from a monomer A of a formula (1) containing bio-derived carbon and/or a monomer B of a formula (2) containing bio-derived carbon, and that has a glass transition temperature of −20° C. or lower.
