Abstract

An absorbent edge coating for masking tape and other masking materials is herein disclosed. A masking tape according to the present invention comprises a substrate having a top surface, a bottom surface, and at least one masking edge. The bottom surface of the substrate has an adhesive layer applied thereto. An absorbent edge coating is applied to at least one masking edge of the substrate so as to at least substantially prevent liquids addressed to the at least one coated masking edge from being absorbed into the substrate of the tape and from passing between the bottom surface of the tape and a surface to which the tape has been applied.
