Abstract
A pressure-sensitive adhesive is prepared by blending (1) a small particle size latex having a hard monomer (such as styrene), a soft monomer (such as butadiene) and, optionally, an acid (such as itaconic acid), and (2) a tackifying resin. These adhesives have an excellent combination of properties including peel adhesion and shear adhesion.
