Abstract

Backing material with a partial self-adhesive coating on at least one side, the application of the self-adhesive composition taking place in the form of geometric structures, wherein for at least some of the geometric structures the base area by means of which the geometric structures adhere to the backing material lies within the area of projection of the geometric structures which is formed as a consequence of the fact that the geometric structures are projected perpendicularly onto the backing material.
