Coated abrasive articles have a composite tie layer. The composite tie layer is preparable by disposing a first polymerizable composition comprising a polyfunctional aziridine on a backing, and disposing a second polymerizable composition comprising at least one acidic free-radically polymerizable monomer and at least one oligomer having at least two pendant free-radically polymerizable groups on the first polymerizable composition, at least partially polymerizing the first and second polymerizable compositions, wherein homopolymerization of the oligomer results in a polymer having a glass transition temperature of less than 50 degrees Celsius.
