Heat-resistant anti-glare screen

Abstract

The anti-glare screen of the invention is composed of an anti-glaring base sheet which is a striped silicone rubber sheet formed of alternately disposed narrow sections of a transparent silicone rubber and a colored, e.g. black, and opaque silicone rubber, each section having a specified width, a transparent lining sheet bonded to one surface of the anti-glaring base sheet and a layer of a pressure-sensitive adhesive on the other surface of the anti-glaring base sheet. By virtue of the high heat resistance of the silicone rubbers, the anti-glare screen can be used to increase the visibility of any displays even when it is heated at an elevated temperature of up to 200.degree. C. as in traffic signals illuminated with an incandescent lamp or as an anti-glare covering in front of a metering panels of automobile dashboards sometimes subject to extreme temperature elevation when the car is prolongedly parked under direct sun shine. Moreover, the transparent lining sheet having rigidity imparts shape retainability to the sheet so that the anti-glare screen can be adapted to any curved surface of display. The layer of the pressure-sensitive adhesive serves not only to facilitate attachment of the screen to the display surface but also to prevent the phenomenon of Newton's rings which otherwise is unavoidable more or less.
