    Abstract: 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, wherein the monomer having a curable ethylenically unsaturated further has a coupling group with a Zerewitinow-active H-atom and wherein the oligomeric organofunctional silicone has at least one coupling group which is reactive to the coupling group of the monomer having a curable ethylenically unsaturated group, or wherein the oligomeric organofunctional silicone has at least one coupling group with a Zerewitinow-active H-atom and wherein the monomer having a curable ethylenically unstaurated further has a coupling group which is reactive to the coupling group of the oligomeric organofunctional silicone; with the proviso that if the monomer having a curable ethylenically unsaturated group further has a coupling group with a Zerewitinow-active H-atom which is selected to be —OH, then the coupling group of the oligomeric organofunctional silicone which is reactive to the coupling group of the monomer having a curable ethylene group cannot be selected to be an amino group.

    Abstract: Provided is a pressure sensitive adhesive article comprising (a) a substrate (Sa), (b) in contact with said substrate (Sa), a layer (Lb) of a composition (Cb) that comprises one or more acrylic polymer (POLb) having Tg of −10° C. or lower, and (c) in contact with said layer (Lb), a layer (Lc) of a composition (Cc) that comprises one or more acrylic polymer (POLc) that comprises 20% to 90% polymerized units of one or more high-aliphatic vinyl monomer, by weight based on the weight of said polymer (POLc). Also provided is a bonded article made by a process of contacting a substrate (Sd) with such a pressure sensitive adhesive article, wherein said substrate (Sd) is in contact with said layer (Lc).
