  • Patent number: 11130889
    Abstract: The present disclosure is directed to a curable precursor of a pressure sensitive adhesive comprising: a) a (co)polymeric material comprising the reaction product of a (co)polymerizable material comprising a (meth)acrylate ester monomer; and optionally, a co-monomer having an ethylenically unsaturated group and which is different from the (meth)acrylate ester monomer; b) a polyfunctional aziridine curing agent; and c) an acid generating agent. The present disclosure is also directed to a method of manufacturing such pressure sensitive adhesives and uses thereof.
    Type: Grant
