  • Patent number: 9421736
    Abstract: A hybrid pressure sensitive adhesive (PSA) composition includes (i) a solvent phase comprising a first acrylic PSA dissolved in an organic solvent, an alcohol, and optionally water; and (ii) an emulsion phase comprising a second, emulsified acrylic PSA. In another aspect, a metalized film laminate includes a metalized film layer, a hybrid PSA layer, and an ink-containing polymeric film layer. The two-phase hybrid PSA system effectively addresses both metal tear and ink pick problems associated with conventional metalized film laminates.
