Abstract
The invention relates to a novel optical function layer and its production, the function layer imparting to materials coated with it protection against uv radiation while transmitting electromagnetic radiation of larger wavelengths. The function layer of the invention and the manufacturing method of the invention offer advantages over the state of the art by allowing very accurate and precise adjustability in the uv range of the relatively sharp absorption constant.
