Abstract:
A pre-adhesive composition is described comprising an acid-functional (meth)acrylate copolymer and an aziridine crosslinking agent, which when crosslinked provides a pressure-sensitive adhesive and pressure-sensitive adhesive articles.
Abstract:
A pressure sensitive adhesive composition is described that comprises a (meth)acrylic polymer comprising polymerized units of (meth)acrylic ester monomer having a Tg less than 0C and ethylenically unsaturated monomer comprising a pendent functional group crosslinked with an amine or carboxylic acid group of at least one amino acid. Also described are aqueous pressure sensitive adhesive compositions, adhesive-coated articles, and methods.
Abstract:
A pressure-sensitive adhesive is provided that is a dried product of a latex composition, which is formed from an emulsion composition. The latex composition and the emulsion composition are also provided. The emulsion composition has droplets that contain various monomers plus a (meth)acrylate polymer dissolved in the monomers. Additionally, an article containing a layer of the pressure-sensitive adhesive and a method of forming the pressure-sensitive adhesive are provided. The pressure-sensitive adhesives often have both high peel adhesion and high shear strength (i.e., high cohesive strength or high shear holding power).
