Abstract

Communication board (1) with an enamelled surface (3), characterised in that a multilayer anti - reflection coating is affixed to the visible side of the enamel layer, consisting of at least three glassy or ceramic layers (4, 5, 6, 7, 8), in which at least one layer has an optical layer thickness outside the range from 50 to 200 ran, and whereby the optical layer thickness of this layer is equal to one quarter of the wavelength of the incident light in nm, divided by the refractive index of the glassy or ceramic layer, and whereby this refractive index is between 1.3 and 1.5.
