    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).
