Abstract

PURPOSE: An acrylic tackifier containing carboxyl groups is incorporated with a specific isocyanate and xylene resin to prevent the leaching out to the tape base and the migration to the back surface.
CONSTITUTION: To 100 parts by wt of an acrylic tackifier bearing carboxyl groups such as acrylic acid-acrylate copolymer are added a small amount of a three- functional isocyanate and over 6 parts of a xylene resin of over 3% methylol group content to form said composition. The tape base is coated with the resulting composition wherein the control of the isocyanate added to a level of less than the amount of carboxyl groups increases the cohesion strength. The resulting adhesive tapes are high flexible and peeling-free even when used in high-thickness articles.
