ADHESIVES AND RELEASE LINERS WITH PYRAMIDAL STRUCTURES

摘要

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 fr om a plane of the surface. The structures have at least three sidewalls. A firs t 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 90~. Th e first sidewall angle differs from the second sidewall angle by more than 10~ .
