A linerless two-sided adhesive tape made of a translucent vellum that is coated with a primer formulated to bond adhesives tightly to the paper. The adhesive consists of a microsphere formulation applied via a gravure-transfer method. The adhesive is comprised of discreet, internally crosslinked, solid spheres of acrylic adhesive, generally in 20 to 50 microns in diameter. The coating process results in random but consistent patterns of microspheres laid out in short lines. The linerless two-sided tape can also be prepared with different microsphere adhesive formulations for increased tackiness or differential adhesion levels from one side to the other. Color dispersions added to the primer or adhesives may be used to change the appearance of the tape if desired.
