Abstract: The present invention provides a UV debondable pressure sensitive adhesive composition and an adhesive tape comprising the same. The UV debondable pressure sensitive adhesive composition comprises a polyacrylate pressure sensitive adhesive, a UV-light polymerizable polyurethane oligomer, a cationic photoinitiator and a free radical photoinitiator, wherein polymerization monomers of the polyacrylate pressure sensitive adhesive comprise an acrylic monomer having an epoxy functional group. The UV debondable pressure sensitive adhesive composition has a bonding force dropping significantly upon UV irradiation, and leaves no residual adhesive.
