摘要： The present invention relates to a multilayer pressure sensitive adhesive (PSA) film having adhesive properties at its first and second main surface, wherein the film comprises at least two superimposed layers of a polymeric pressure sensitive adhesive foam material and optionally one or more intermediate layers of a polymeric foam material, wherein the PSA film is obtainable by a continuous self-metered process comprising the steps of (a) providing a substrate, (b) providing two or more coating knives which are offset, independently from each other, from said substrate to form a gap normal to the surface of the substrate, (c) moving the substrate relative to the coating knives in a downstream direction, (d) providing curable liquid precursors of the polymeric pressure sensitive adhesive foam materials and optionally of the polymeric foam material to the upstream side of the coating knives thereby coating the two or more precursors through the respective gaps as superimposed layers onto the substrate, (e) optionally providing one or more protective liners and applying these along the upstream side of the coating knives, and (f) curing the precursor of the multilayer film thus obtained, wherein a lower layer of the curable liquid precursor is covered by an adjacent upper layer of the curable liquid precursor, essentially without exposing said lower layer of a curable liquid precursor.
