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.degree. and less than 90.degree. and
a second sidewall makes an angle with respect to the plane of the surface
of greater than 0.degree. and less than about 90.degree.. The first
sidewall angle differs from the second sidewall angle by more than about
10.degree..
