Disclosed herein is a microstructured tool having a microstructured layer on a base layer. The microstructured layer is made from an aromatic acrylate polymer that is a reaction product of an oligomer and a radiation curable diluent, the aromatic acrylate polymer having a ratio of aromatic to aliphatic carbons of less than about 1:1, the oligomer comprising a multifunctional acrylate monomer or an acrylate functionalized oligomer. The microstructured layer has a microstructured surface having one or more features. The base layer may be metal, polymer, ceramic, or glass. Also disclosed herein is a method of making the microstructured tool using laser ablation. The microstructured tool may be used to make articles suitable for use in optical applications.
