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.

Abstract: Protective film articles include a thermally stable tape backing with a first major surface and a second major surface, a primer layer on the first major surface of the thermally stable tape backing, and a self-wetting, tack-free adhesive layer at least partially coated on the primer layer. The tack-free adhesive layer includes at least one siloxane-based elastomeric polymer that is thermally stable, and is able to removably adhere to an optical or electronic device without leaving residue on the optical or electronic device. The protective film articles can be used in the preparation of a wide range of optical and electronic articles.

Abstract: The present invention provides a thermally curable pressure-sensitive adhesive composition, which, based on the total weight of the composition, comprises the following components: a) 35-99% by weight of a reactive polymethacrylate component having a glass transition temperature Tg of ?35° C. to 32° C., and having a reactive functional group which can react with benzoxazine to form an interpenetrating polymer network; and b) 1-65% by weight of a benzoxazine component of the following formula: wherein: X is selected from the group consisting of a covalent bond, C1-C6 alkylene, C3-C10 cycloalkylene group, C?O, S, S?O or O?S?O R1 and R2 are the same or different and independently of each other selected from the group consisting of hydrogen, C1-C6 alkyl, or C5-C14 aryl, and R4 is selected from the group consisting of hydrogen, halogen or C1-C6 alkyl.
