Abstract
The present application is directed to adhesive articles and release liners. Namely, the present application is directed to an article comprising an adhesive layer with a structured surface. The structured surface comprises a first groove and a second groove recessed into the adhesive layer from a reference plane defined by the adhesive surface on either rim of the groove. In some embodiments, the second groove is contained within the first groove, and in other embodiments the grooves are separate. The first groove and the second groove have walls. The wall angle of the first groove with respect to the reference plane is non-zero and is smaller than the wall angle of the second groove with respect to the reference plane. The application is also directed to release liners for the adhesive article, wherein the surface of the release liner is the inverse of the adhesive surface.
