Abstract: The invention relates to a method for production of a coated substrate, whereby at least one functional layer is deposited on the substrate from the vapor phase by means of chemical or physical deposition of a coating material and a temporary protective layer is applied to the functional layer by means of evaporation of a salt, in particular, an alkali metal halide. The invention further relates to a coated substrate with at least one functional layer and a temporary protective layer applied to the functional layer, which comprises a salt, in particular, an alkali metal halide, preferably a salt-like alkali metal halide and more particularly sodium chloride.

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%.

Abstract: A process for coating plastic substrates with a transparent layer compact that is not sensitive to scratches and abrasion and resistant to atmospheric influence with a plasma flame in a vacuum chamber at some distance from the substrate. The process includes the steps of: a cleaning of the substrate with an oxidizing gas in a first procedural step and then a cross linkage with an inert gas in a second procedural step, an oxidizing gas and a silicon-organic compound are used in a third procedural step to produce a first barrier layer, and an oxidizing gas, a silicon-organic compound, and a UV-absorbing compound are used in a fourth procedural step to deposit a sublayer with UV absorbers, an oxidizing gas and a silicon-organic compound are used in a fifth procedural step to deposit a scratch-resistant layer, an inert gas and a silicon-organic compound are used in a sixth procedural step to deposit a smooth layer.
