A coated substrate is disclosed. The substrate is coated on at least one side with a continuous layer of a pressure-sensitive adhesive having a microstructured surface. The microstructured surface has a series of features, each of the features having a height 2.5 to 375 micrometers, a spacing aspect ratio of greater than 1 to 1.9, and a lateral aspect ratio of from 0.1 to 10. At least two dimensions of each feature selected from the group consisting of length, width, and depth or height, are microscopic. |
