Abstract
A method of making a coated abrasive article includes disposing abrasive composite precursors on a major surface of a water-soluble film. The abrasive composite precursors are lightly contacted with a porous fibrous backing, and the abrasive composite precursors are hardened to form abrasive composites. Dissolving the water-soluble film provides the coated abrasive article.
