    摘要: A pressure-sensitive adhesive comprising an aqueous polymer dispersion prepared by emulsion polymerization, wherein the polymer comprises monomers containing a hydroxyl group or primary amino group (referred to below collectively for short as hydrophilic monomers) and the polymer is obtainable by supplying more than 70% by weight of the hydrophilic monomers only when the polymerization mixture (mixture present in the polymerization vessel and composed of monomers and polymer already formed) already comprises more than 50% by weight of the total amount of monomers.
