Abstract: Adhesives suitable for use with low surface energy materials are described. The adhesive contain an acrylic copolymer, a high glass transition temperature tackifier and a low glass transition temperature tackifier. The acrylic copolymer is the reaction product of a first alkyl(meth)acrylate having at least 5 carbon atoms in the alkyl group, a second alkyl(meth)acrylate having 1 to 4 carbon atoms in the alkyl group, and a vinyl carboxylic acid. Both tackifiers have a Tg greater than the Tg of the acrylic copolymer. The high glass transition temperature tackifier has a Tg of at least 20° C. and the low glass transition temperature tackifier has a Tg of less than 0° C.

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 and a hydrogenated hydrocarbon tackifier 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).
