The present disclosure relates to a multilayer pressure sensitive adhesive assembly comprising at least a first pressure sensitive adhesive layer superimposed to a second polymer layer, wherein a curable liquid precursor of the first pressure sensitive adhesive polymer layer comprises a low Tg (meth)acrylate copolymer and a high Tg (meth)acrylate copolymer having a weight average molecular weight (Mw) of above 20,000 Daltons. The present disclosure also relates to a method of manufacturing such a pressure sensitive adhesive assembly and uses thereof.

Multilayer pressure sensitive adhesive assembly

A multilayer pressure sensitive adhesive (PSA) film having a first pressure sensitive adhesive layer for bonding glass substrates and at least a second opposing layer, the first pressure sensitive adhesive layer being a polymerization reaction product of a precursor comprising a monomer or a partially prepolymerized monomer, having a curable ethylenically unsaturated group, whereas the precursor further comprises an oligomeric organofunctional silicone having at least 2 Si atoms, in particular 2 to 10 Si atoms,
