Abstract: A coated abrasive article comprises an abrasive layer secured to a backing. The abrasive layer comprises abrasive particles secured by at least one binder to a first major surface of the backing. A supersize is disposed on at least a portion of the abrasive layer. The coated abrasive article has a melt flow zone adjacent to an edge of the coated abrasive article, wherein the melt flow zone has a maximum width of less than 100 micrometers, and the melt flow zone has a maximum height of less than 40 micrometers. Methods of using infrared lasers to ablate coated abrasive articles are also disclosed, wherein a laser wavelength is matched to a component of the coated abrasive article.
