Abstract: The present disclosure relates to a pressure sensitive adhesive composition, comprising: a) a first (meth)acrylate copolymer comprising from 0.1 to 12 wt % of (meth)acrylic acid monomer units, based on the weight of the first (meth)acrylate copolymer; and b) a second (meth)acrylate copolymer comprising from 15 to 40 wt % of (meth)acrylic acid monomer units, based on the weight of the second (meth)acrylate copolymer. According to another aspect, the present disclosure is directed to a multilayer pressure sensitive adhesive assembly comprising a pressure sensitive adhesive composition as described above in the form of a first pressure sensitive adhesive polymeric layer, and which further comprises a second pressure sensitive adhesive layer adjacent to the first pressure sensitive adhesive polymeric layer. In another aspect, the present disclosure is directed to a method of manufacturing a pressure sensitive adhesive composition as described above and to uses thereof.
