Abstract

The fibres are at least partially sized. Transparent acrylic polymer screen contains polymeric fibers, that hold the pieces together in the event of a breakage. The fibres are at least partially sized. An Independent claim is also included for production of the screen by embedding the pre-sized fibers in the acrylic polymer.
