An absorbent edge coating (36) for masking tape (30) and other masking materials is herein disclosed. A masking tape (30) according to the present invention comprises a substrate having a top surface, a bottom surface, and at least one masking edge (40a). The bottom surface of the substrate has an adhesive layer (34) applied thereto. An absorbent edge coating (36) is applied to at least one masking edge (40a) of the substrate so as to at least substantially prevent liquids addressed to the at least one coated masking edge (40a) 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.
La présente invention concerne un revêtement de chant absorbant (36) destiné à du ruban-cache (30) et autres matériaux masquants. Le ruban-cache (30) de l'invention comprend un substrat définissant une face supérieure, une face inférieure, et au moins un bord masquant (40a). La face inférieure du substrat est enduite d'une couche de colle (34). En outre, un revêtement de chant absorbant (36) garnit l'un au moins des chants masquants (40a) du substrat de façon à éviter au moins sensiblement que les liquides aboutissant sur ce chant masquant enduit (40a) ne soient absorbés dans le substrat du ruban et ne passent entre la face inférieure du ruban et une surface sur laquelle le ruban est appliqué.
