ABSTRACT:
A layer construction with an organic layer and a transparent cover layer which covers the organic layer and which is harder than the organic layer, and a process for producing such a layer construction in which the cover layer is deposited on the surface of the organic layer from a precursor material present in the gas phase. In order to improve the optical quality of the layer construction, the cover layer, at least in a transition region between the organic layer and the cover layer, is deposited with an index of refraction which differs by a maximum of 20%, in particular by a maximum of 10%, from the index of refraction of the underlying organic layer.
