ABSTRACT:
A window for use in a convertible top comprises a thin, flexible, optically transparent plastic sheet and a thin, flexible, optically transparent thermoplastic abrasion-protective coating applied to both faces of the plastic sheet. The abrasion-protective coating comprises a weatherable polymer such as an acrylic polymer which is transparent in thin film form and adhered to the plastic sheet as a semi-permanent coating removable by an alkaline water-based cleaning agent. The thin-film form coating provides a level of abrasion protection by preferentially abrading while protecting the underlying clear plastic window from scratching. A preferred coating comprises a water-based emulsion of an acrylic polymer such as an acrylic floor polish diluted with water and applied to the window by a dipping process.
