Abstract: An adhesive film includes a first (meth)acrylate copolymer containing at least 55 weight percent (wt. %) of linear or branched alkyl (meth)acrylate monomer units, from 15 to 40 wt. % of (meth)acrylic acid monomer units, and 0.1 to 5 wt. % of monomer units of a crosslinking monomer having more than one (meth)acrylate group. If the first (meth)acrylate copolymer comprises 15 wt. % (meth)acrylic acid monomer units, the first (meth)acrylate copolymer comprises at least five wt. % monomer units of a high Tg monomer. The adhesive film comprises not more than five wt. % of a further (meth)acrylate copolymer comprising from 0.1 to 15 wt. % of (meth)acrylic acid monomer units. The adhesive film can be a multilayer adhesive assembly including a first layer of the first (meth)acrylate copolymer and a second adhesive layer adjacent to the first layer. A process for making and a system including the adhesive film and a primer are also described.
