Coated abrasive article
 The present invention provides a coated abrasive article, wherein the backing includes a tough, heat resistant, thermoplastic binder material, and an effective amount of a fibrous reinforcing material distributed throughout the thermoplastic binder material. The abrasive grain adhered to the backing comprise rare earth oxide-modified alpha alumina-based abrasive grain, which exhibit a surprising improvement in grinding performance in conjunction with the backing.
