Adhesive articles having repositionability or slidability characteristics
First Claim
1. An adhesive article comprising:
- an embossed release liner having a release surface and a back surface;
an embossed adhesive layer having a front surface and a back surface, the front surface of the adhesive being adhered to the release surface of the release liner and wherein a second release liner is adhered to the back surface of the adhesive layer, the front surface containing recessed areas and the recessed areas define a plurality of recessed surfaces; and
a plurality of surface contact elements randomly distributed about the release surface of the release liner, wherein one or more of the surface contacts are at least partially embedded within the recessed areas and wherein one or more of the surface contact elements are at least partially embedded into the release liner; and
wherein the surface contact element forms are random in one or more physical parameters selected from a group including size, shape, thickness, height, width, circumference, density, volume and combinations thereof.

Abstract
An adhesive article exhibiting air release or egress, repositionability, and/or slidability characteristics. An adhesive article comprises an adhesive layer comprising an adhesive surface comprising discrete forms of non-adhesive material randomly distributed on the patterned surface and at least partially embedded in the adhesive layer. The discrete forms of non-adhesive material provide areas of no or minimal adhesion and provide the article with some level of repositionability or slidability. The adhesive surface comprising the non-adhesive forms may be patterned to provide an adhesive surface with a contact surface and recessed area or channels that provide the article with a route for air to flow out from under the construction. An article may be formed by providing a release liner, applying discrete forms of non-adhesive material to a surface of the release liner, at least partially embedding the non-adhesive forms, and embossing the release liner.
