Abstract:
Methods for producing tooling and sheeting using laser writing techniques, and corresponding products thereof, are presented. In one embodiment, a seamless sheet having a plurality of microstructures formed in a continuous microstructured pattern is provided. In the methods described herein, a substrate having a photosensitive coating on a surface thereof is provided. A surface-relief microstructured pattern is produced in the photosensitive coating by selectively exposing the photosensitive coating to a beam of electromagnetic radiation. The exposed portions of the photosensitive coating are developed to form a microstructured pattern on the surface of the substrate. The microstructured pattern is then transferred into retroreflector tooling comprising the microstructured pattern on a surface thereof. A sheet containing the microstructured pattern on a surface thereof is then formed from the retroreflector tooling.
