    摘要: 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.

    摘要: An optical element having a front side and a back side operates in an ambient lit mode and a backlit mode. The optical element includes a diffusely reflecting layer facing the front side for reflecting ambient light. A light absorbing layer faces the back side and is positioned to prevent back light from illuminating the diffusely reflecting layer. A plurality of light transmitting regions extend through the light absorbing layer and the diffusely reflecting layer for permitting back light to pass through in a restricted angular range without illuminating the diffusely reflecting layer.
