Zusammenfassung:	An adhesive article includes a release liner and an adhesive layer on the surface of the release liner. The release liner has a surface with an arrangement of structures thereon, wherein the structures extend downward from a plane of the surface. The structures have at least three sidewalls. A first sidewall makes an angle with respect to the plane of the surface of greater than about 0° and less than 90° and a second sidewall makes an angle with respect to the plane of the surface of greater than 0° and less than about 90°. The first sidewall angle differs from the second sidewall angle by more than about 10°.
