Abstract
A pressure sensitive adhesive(PSA) composition includes a latex system of an aqueous polymer dispersion derived from ethylenically-unsaturated monomers in the presence of a water soluble protective colloid. The PSA compositions are used in the manufacture of a variety of articles that are intended to be easily attachable to another substrate by the application of pressure alone.
