Summary: | Primer layers for adhesion of pressure sensitive adhesive materials to substrates comprise a cured primer which is the reaction product of an epoxy resin and a polyamine. The epoxy resin may be an aromatic epoxy resin. The polyamine may be a polymer such as polyethylenimine (PEI) or polyvinylamine (PVA). Two-layer constructions comprise the primer layer according to the present disclosure and a substrate layer, which may be directly bound to the primer layer. The substrate layer may comprise one or more polyester polymers, may comprise one or more polymers comprising aromatic groups, and/or may comprise polyethylene terephthalate (PET). Tapes comprise the two-layer construction according to the present disclosure and a pressure sensitive adhesive layer, which may be directly bound to the primer layer. The tape may comprise a second pressure sensitive adhesive layer borne on the opposite face of the tape and optionally a foam layer. |
