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: Cationic or zwitterionic polymer adhesives, adhesive articles, aqueous polymerizable pre-adhesive reaction mixtures, and methods of preparation that include internal incorporation of a phenolic resin. The aqueous polymerizable pre-adhesive reaction mixtures include one or more cationic (meth)acrylate monomers, one or more low Tg nonionic monomer having a (meth)acryloyl group, optionally one or more anionic (meth)acrylate monomers, and one or more phenolic resins.
