    Abstract: Retroreflective articles comprise a substrate and a bar code provided on the substrate. The bar code comprises at least one human-readable information which provides framing information and a machine-readable information which provides variable information. The human-readable information is visible under a first condition and invisible under a second condition, and the machine-readable information is invisible under the first condition and visible under the second condition.

    Abstract: Optical bodies, for example optical films, are formed with inorganic fibers embedded within a polymer matrix. In some embodiments, the refractive indices of the inorganic fibers and the polymer matrix are matched. There need be no bonding agent between the fibers and the polymer matrix. The inorganic fibers may be glass fibers, ceramic fibers, or glass-ceramic fibers. A structure may be provided on the surface of the optical body, for example to provide optical power to light passing through the optical body. The body may be formed using a continuous process, with a continuous layer of the inorganic fibers being embedded within the matrix which is then solidified.

    Abstract: 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.
