Abstract
A pressure-sensitive adhesive having improved shear strength obtained by virtue of the formation of the enamine of a pendent acetoacetate is described. These materials contain acetoacetate functional monomer in a low Tg emulsion polymer. Shear strength is improved without compromise of either peel strength or tack.
