MULTILAYER FILM

摘要

The present application is directed to a multilayer film. The film comprises a thermoplastic receptor layer comprising a polyurethane, a thermoplastic core layer on the receptor layer comprising an acidic group or an anhydride group, and a thermoplastic primer layer on the core layer opposite the receptor layer comprising a nitrogen containing polymer. In some embodiments, the multilayer film includes additional layers. For example, an adhesive layer may be on the primer layer opposite the core layer. In another embodiment, a release layer is on the adhesive layer opposite the primer layer. In another embodiment, a liner layer is on the release layer opposite the adhesive layer.
