摘要：<p>A water-based pressure sensitive adhesive dispersion is provided. The dispersion is a reaction product of a monomer solution and an aqueous phase. The monomer solution contains from about 40 to 70 parts water-insoluble monomer selected from the group consisting of alkyl acrylate, methacrylate, vinyl ester, and combinations thereof and from about 0.01 to 0.2 parts monomer soluble free radical initiator. The aqueous phase includes from about 1 to 20 parts latex binder, from about 0.1 to 2 parts surfactant, from about 0.02 to 1 parts polymeric suspension stabilizer, and water as a remaining balance. All parts are given as parts by weight per 100 parts of the dispersion. The dispersion has a solid phase of at least 60 weight percent, a viscosity of less than about 300 centipoise, measured at about 23° C., and a bimodal particle size distribution.</p>
