Abstract
This invention encompasses abrasive articles that have a coating, typically made of at least a binder and abrasive particles, selectively removed from a portion of an exposed abrading surface of the article in order to inscribe a detectable marking on the abrasive article. Suitable coated abrasive articles include both articles that have the binder and abrasive particles sequentially coated on a backing as a make coat and deposited abrasive particles as well as articles that have the binder and abrasive particles simultaneously coated on the backing as a slurry coat. Coated abrasive articles that are particularly preferred include articles that have an exposed abrading or abrasive surface that is a textured, three-dimensional surface.
