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.
