Abstract

Surface-modified adhesives may be prepared by contacting an adhesive layer to an at least partially discontinuous layer on a releasing substrate and removing the adhesive layer such that at least a portion of the at least partially discontinuous layer adheres to the adhesive surface. The modified adhesive surface remains an adhesive surface. The modified adhesive layer can be used to prepare adhesive articles, including articles containing multiple surface-modified adhesive layers.
