ABSTRACT:
Abrasive articles and a method for the manufacture of the articles are described. The articles comprise a backing having a first major surface and a second major surface; a first resin layer comprising a first hardened resin, the first resin layer extending over the first major surface of the backing; abrasive particles adhered within the first resin layer; a second resin layer applied over the first resin layer, the second resin layer comprising a second hardened resin; and a lofty, three dimensional, nonwoven web of fibers bonded to one another at their mutual contact points and extending through the first and second resin layers. The dry coating weights of the first and second hardened resins are about 400 g/m.sup.2 or greater and preferably greater than about 600 g/m.sup.2.
