Abstract

In a method for the coating of substrates made of plastic, with a light-reflecting layer, preferably an aluminum layer, and another layer placed between the substrate and the light-reflecting layer, the additional layer, which has a high barrier effect to substances which migrate or evolve gases from the plastic, is a highly crosslinked hydrocarbon layer, a silicon dioxide, silicon nitride, or silicon oxynitride layer, with a thickness of at least 15 nm, wherein the carbon content of the barrier layer is <15%.
