Abstract: An abrasive article comprising an attachment layer and an abrasive layer. The attachment layer comprises a porous backing having a first major surface, an opposed second major surface, and a first plurality of voids extending from the first major surface to the second major surface. The abrasive layer has a third major surface and an opposed fourth major surface and comprises a cured composition, abrasive particles at least partially embedded in the cured composition, and a second plurality of voids extending from the third major surface to the fourth major surface. The first major surface of the attachment layer is adjacent the third major surface of the abrasive layer, and the pattern of the second plurality of voids is independent of the pattern of the first plurality of voids.
