ABSTRACT:
This invention describes water-based microsphere adhesive formulations to be used in the sheet-to-sheet coating process. These adhesives have proven to have excellent wet-out of a difficult, high-energy surface, good shear stability to allow die-coating or gravure-coating of the adhesive onto an intermediate carrier belt, good elasticity to allow the wet adhesive to cling to the intermediate belt until it is dried (or partially dried), good integrity to allow complete transfer from the intermediate carrier belt onto the final substrate, and repositionable properties in a final product composition.
