Abstract: A transparent coating is used on an optical information disk. The optical information disk is an injection-molded piece of clear poly-carbonate plastic and is impressed with microscopic bumps which are arranged as a single, continuous, extremely long spiral track of data. A thin, reflective aluminum layer is sputtered onto the optical information disc so that the thin, reflective aluminum layer covers the bumps. A thin acrylic layer is sprayed over the thin, reflective aluminum layer in order to protect it. The transparent coating is a composite material which is made of silica as the discontinuous phase and of a polytetrafluoro-ethylene-derived organic polymer as the continuous phase which leads to a fluorine-containing silica-based product. The transparent coating is applied by spin or dip from specific solutions at room temperature followed by a mild and short heat treatment.
