PROCESS OF STRIPE COATING TO PRODUCE MICROSTRUCTURED COMPOSITE ARTICLES

摘要

Described is a process for producing a microstructured composite article including the steps of: providing a tool with a molding surface that is suitable for forming a microstructure; applying to at least a portion of the molding surface a plurality of lines of a flowable, curable resin composition; contacting the resin composition with a substrate; curing the resin composition; and, transferring the resin composition to the substrate. Alternative embodiments include heating the molding surface or resin composition, or both, to aid in the flow of the resin composition. The advantage of this process is that is that the microstructured composite articles are able to be produced at high speed and are free of air bubbles.
