1. A coated abrasive article having a patterned abrasive surface, the article comprising:
- a substrate having a periphery, a first side and a second side opposite said first side and comprising a thermoplastic material;
said first side having a plurality of raised portions suitable for the application of an abrasive coating thereon, and recessed areas extending around said periphery on said first side and between said raised portions, said second side being substantially planar;
a first adhesive layer applied to said raised portions; and
an abrasive material deposited onto said first adhesive layer thereby coating said raised portions to form an abrasive coating, said recessed areas remaining substantially free of said abrasive material.

Abstract
An abrasive article having a patterned abrasive surface is provided. In accordance with the present invention, the article comprises a substrate having a first side. A plurality of raised portions are positioned on the first side of the substrate with the raised portions defining recessed areas between each raised portion. A first adhesive layer is applied to the raised portions and an abrasive material is deposited onto the first adhesive layer thereby coating the raised portions of the substrate to form an abrasive coating with the recessed areas remaining free of the abrasive material.

19. A method of making a coated abrasive article, the method comprising:
-
providing a substrate comprising a thermoplastic material, said substrate having a periphery, a first side and a second side opposite said first side;
forming raised portions in said first side of said substrate so that said first side consists of said raised portions suitable for the application of an abrasive coating thereon with recessed areas extending around said periphery on said first side and between said raised portions and said second side consists of a substantially planar surface;
applying an adhesive layer onto said raised portions, said raised portions providing a means for said adhesive layer to be applied uniformly; and
depositing an abrasive material on the first adhesive layer thereby coating the raised portions of the substrate, the recessed areas remaining substantially free of the abrasive material deposit. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
