Abstract: Method for coating a plastics substrate with a functional layer, wherein (a) in a vacuum chamber, an organic UV absorber which comprises at least one chromophore and at least one reactive side chain is evaporated and (b) is brought into contact with at least one surface of the plastics substrate and excited with a plasma, or (c) is excited with a plasma and then brought into contact with at least one surface of the plastics substrate, whereby a functional layer comprising the UV absorber is formed on the surface of the plastics substrate, the plasma being ignited at a pressure of greater than 10−5 bar and less than 1.013 bar.
