摘要： A multilayer pressure sensitive adhesive (PSA) film having a first acrylic pressure sensitive adhesive layer and an opposing second acrylic pressure sensitive adhesive layer, whereas the inventive film is characterized in that the first pressure sensitive adhesive layer has a glass transition temperature Tg ≥ 0° C and a content of a strongly polar acrylate of 7.5 to 15 wt.-% in its precursor, in particular at least 10 wt.-%, and the second pressure sensitive adhesive layer has a Tg ≤ 0° C and contains 0.5 to 12 wt.-% of a strongly polar acrylate in its precursor, in particular up to 10 wt.-%, wherein the content of the strongly polar acrylate of the precursor of the first pressure sensitive adhesive layer exceeds the content of the strongly polar acrylate of the precursor of the second pressure sensitive adhesive layer by at least 2 wt.-% and wherein the Tg of the first pressure sensitive adhesive layer exceeds the Tg of the second pressure sensitive adhesive layer by at least 5° C.
