Kontrasterhoehende Bildwand

Die vorliegende Erfindung betrifft eine Bildwand zur Darstellung statischer oder bewegter Bilder unter Verwendung von einer oder mehreren monochromatischen Laserlichtquelle(n), wobei die Bildwand eine spektral selektiv reflektierende Beschichtung aufweist und die Bildwand zudem zur Erhoehung der raeumlich selektiven Reflexion eine strukturierte Lackschicht aus einem haertbaren Lack enthaelt.

DE 10245881 A UPAB: 20040527 NOVELTY - A contrast increasing projection screen containing a substrate (3) and a spectrally selective reflecting coating (2) and having at least one 3-dimensional reflecting layer (1) formed from a curable paint is new. USE - The curable paint layer I is useful as a 3-dimensionally selective layer (1) for a projection screen (claimed), consists of an electron beam- or UV-cured paint (claimed), e.g. a cured paint selected from acrylates, epoxides, vinyl ether, optionally substituted styrenes (claimed), especially an acrylate based or a UV-cured paint (claimed). The contrast increasing projection screen can be used for displaying static or mobile images by means of call-projection (sic) via a narrow band light source, e.g. one or more chromatic light sources. ADVANTAGE - The new projection screen provides a 3-dimensional angular characteristic of a spectrally selective reflecting projection screen without the problems of disturbance of spectral selectivity or alteration of the peak position of spectrum wavelength and strong reflection from the background.
