An adhesive-backed article having a compliant film with a pressure sensitive adhesive bonded to one surface of the film. The pressure sensitive adhesive includes a microstructured surface opposite the compliant film. The microstructured surface defines channels in the adhesive. The channels create pathways for the egress of fluids. Upon application onto a substrate, the channels and structures wet out to render the microstructured surface substantially undetectable when viewed from the exposed surface of the article.

L'invention concerne un article à envers adhésif, comprenant un film souple sur une surface duquel un adhésif sensible à la pression est appliqué. Ledit adhésif sensible à la pression comporte une surface microstructurée opposée au film souple. La surface microstructurée délimite des canaux dans l'adhésif. Les canaux créent des passages pour l'évacuation des fluides. Lors de l'application de l'article sur un substrat, les canaux et les structures rejettent les fluides de sorte que la surface microstructurée soit sensiblement invisible lorsqu'elle est vue depuis la surface exposée de l'article.
