Abstract:
A hard coating composition for use as a stain repellent single layer on an optical display. The coating composition adds a monomer of a mono or multi(methyl)acrylate bearing at least one monovalent hexafluoropolypropylene oxide derivative and a free radically reactive compatibilizer consisting of either a fluoroalkyl-group containing acrylate compatibilizer or a fluoroalkylene-group containing acrylate compatibilizer to a conventional hydrocarbon-based hard coat formulation. The resultant coating is substantially smooth and forms a durable surface layer that has low surface energy that is stain and ink repellent.
