The present invention comprises a multilayer inorganic anti-reflective coating with predetermined optical properties, for application on a flexible substrate. The coating comprises a stack consisting of five material layers, whereby the third layer is a dummy layer consisting of an electrically conductive material, preferably indium-tinoxyde, which provides the coating with an adjustable electrical sheet resistance of between 25 and 2000 &#x3a9;/sq without thereby influencing its optical properties. The anti-reflective coating can be applied onto a flexible substrate (e.g. a polymer film) by means of a single 12 or double pass vacuum magnetron sputtering operation.

Multilayer electrically conductive anti-reflective coating

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 and an optional top coat on a flexible glass substrate 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 is provided with anti-reflective coating using a continuous web coating process while being laminated to a polymer support by using adhesive layer . Upon delamination (arrows ) the adhesive layer may remain fixed to glass substrate (right embodiment of FIG. ) or to polymer support (left embodiment of FIG. ). After said delamination the glass substrate provided with anti-reflective coating may be adhered to the front panel of an information display device.

Laminated metal structure

An antipiliferage tag comprising a soft-magnetic thin film (100) for use as an active element in an electronic article surveillance (E.A.S.) system. The film (100) has an easy axis (102) with a particular direction. The tag has been folded along at least one folding line (104) so that the tag comprises at least two layers which at least partially overlap with each other. The folding line (104) forms an oblique angle different from zero with the direction of the easy axis (102) so that the direction of the easy axis (102) in one layer is different from the direction of the easy axis (106) in another layer. In this way an antipiliferage tag which is insensitive to its orientation in a detection gate of an E.A.S. system is obtained.
