Abstract:
A window for use in a vehicular convertible top, in which the window is sufficiently flexible and foldable to enable repeated folding and unfolding of the window during use of the convertible top, the convertible top window comprising an optically transparent plastic substrate sheet; and a protective outer film layer comprising an optically transparent abrasion-resistant protective dry film adherently bonded as a permanent coating to at least one face of the plastic substrate sheet, the protective outer film layer comprising a weatherable polyurethane material which is transparent in film form, a cross-linking agent reacted with said polyurethane material, and a lubricant additive blended with said polyurethane material, said protective outer film layer having a level of abrasion resistance sufficient for use as a convertible top window and a self-lubricating exterior surface which enables repeated folding and unfolding of the finished window without self adhesion of the contacting surfaces.
