Abstract
A pressure-sensitive adhesive construction repulpable in paper recycling operations, comprising a facestock which is repulpable; a dispersible pressure-sensitive adhesive comprising tacky emulsion polymers dispersible in water; and a nondispersible pressure-sensitive adhesive comprising tacky emulsion polymers not dispersible in water, wherein, on the facestock, the dispersible pressure-sensitive adhesive is closer to the facestock than the nondispersible pressure-sensitive adhesive, thereby improving both adhesive performance and recyclability.
