Abstract
A material is disclosed which is suitable for reducing the reflection of information displays such as a CRT, LCD, plasma tube, etc., and is characterised by an improved pencil hardness and excellent optical properties (lower average reflection, higher bandwidth). The anti-reflection material of the invention comprises an anti-reflective coating 20 and an optional top coat 10 on a flexible glass substrate 30 that is capable of being wound around a cylindrical core having a radius of 1.5 m. In a preferred method of the present invention the glass substrate 30 is provided with anti-reflective coating 20 using a continuous web coating process while being laminated to a polymer support 50 by using adhesive layer 40. Upon delamination (arrows 60) the adhesive layer 40 may remain fixed to glass substrate 30 (right embodiment of FIG. 1) or to polymer support 50 (left embodiment of FIG. 1). After said delamination the glass substrate 30 provided with anti-reflective coating 20 may be adhered to the front panel of an information display device.
