Abstract
A primer coating composition for use in polyolefin-backed pressure sensitive tape comprising a maleic anhydride modified chlorinated polyolefin covalently bonded to a maleic anhydride modified A-B-A block copolymer, where A is a thermoplastic polystyrene and B is a rubber midblock, by means of a crosslinking agent capable of reacting with the maleic anhydride functional groups in said polyolefin and said block copolymer a polyolefin-backed pressure sensitive tape employing the primer coating composition; and a method for manufacturing a polyolefin-backed pressure sensitive tape employing the primer coating composition are described.
