Patent Images
1. A coated abrasive article comprising:
- (a) a backing;
(b) at least one layer comprising a plurality of precisely shaped abrasive composites that comprise abrasive grits and a binder formed from a free radically polymerizable binder precursor, wherein said precisely shaped composites have vertexes, and wherein the precisely shaped composites are randomly disposed on the backing such that at least a portion of said particles are oriented with said vertexes point toward said backing;
(c) a bonding medium which serves to adhere said precisely shaped particles to said backing.
