Abstract: The present invention relates to a double-sided adhesive tape used for applications including the attachment of front glass for mobile devices. A core layer of the double-sided adhesive tape is prepared by adding an acrylic elastomer free of carbon-carbon double bonds while being highly miscible with an acrylic resin to an acrylic monomer(s) and performing curing, and thus can improve the impact resistance of the final double-sided adhesive tape. Also, the core layer may take a form of foam due to the introduced filler such as glass bubbles or organic microspheres, and thus can further contribute to improving the impact resistance of the final double-sided adhesive tape.

Abstract: Provided is a double coated tape with improved reworkable capability, in which a first adhesive layer, a film carrier layer, a foam carrier layer, and a second adhesive layer are sequentially stacked, and which includes a thermoplastic polyurethane (TPU) film located between the foam carrier layer and the second adhesive layer. Since the double coated tape is used for bonding of an LCD panel to a frame, while providing improved light leakage performance and reworkable capability, the double coated tape is advantageously used when manufacturing an electronic appliance such as a television, a cellular phone, and a computer.
