This invention relates to an adhesive article which provides air egress.
Air egress is provided by supplying a route, such as areas of no initial
adhesion for the air to flow out from under the construction. The
invention relates to an adhesive article comprising a facestock having a
front surface and a back surface, a continuous layer of adhesive having
an upper surface and a lower surface wherein the upper surface of the
adhesive layer is adhered to the back surface of the facestock, and a
plurality of spaced-apart non-adhesive material which is in contact with
the lower surface of the adhesive layer wherein the lower surface of the
adhesive layer has a Sheffield roughness of at least about 10 and the
adhesive article provides air egress. The invention also relates to
methods of preparing the adhesive articles. These articles have
usefulness as industrial graphics images, as well as decorative
coverings, etc. The articles provide air egress and optionally
repositionability and slideability.
