An abrasive article, comprising:
- a) an embossed isolation layer defining contoured first and second surfaces with a plurality of peaks on the first surface producing a plurality of pockets on the second surface,
- b) grinding aid-containing protrusions positioned in the pockets, wherein the grinding aid is selected from the group consisting of halogenated thermoplastics, sulfonated thermoplastics, waxes, halogenated waxes, sulfonated waxes, and mixtures thereof, and
- c) a coating of abrasive particles adhered to the contoured first surface of the isolation layer.
