The abrasive particles consist essentially of ceria particles having an average primary particle size of less than 100 nanometers. The binder comprises a polyether acid and a reaction product of components comprising a carboxylic(meth)acrylate and a poly(meth)acrylate, and, based on a total weight of the abrasive layer, the abrasive particles are present in an amount of at least 70 percent by weight. Methods of making and using the structured abrasive article are also disclosed.
