Abstract
Coated abrasive articles comprise a backing and an abrasive layer, and optionally at least one of a backsize layer, tie layer, supersize layer, presize layer, or saturant. The coated abrasive article comprises a reaction product of components comprising: polyfunctional acrylate; polyfunctional cationically polymerizable material; free radical photoinitiator; triarylsulfonium salt having the formula 1 wherein R1, R2 and R3 independently represent an, optionally substituted, aromatic group having from about 4 to about 20 carbon atoms, and Y− represents a non-interfering anion; and quaternary ammonium salt having the formula 2 wherein X− is a non-interfering anion.
