摘要：
The invention relates to a multi-layer structure containing a thermoplastic substrate, a barrier layer, a UV protection layer, and a cover layer: 1. a thermoplastic substrate material, 2. a barrier coat containing silicon-based precursors, 3. a UV protection layer based on a metal oxide (Me

y /O
x > 1, preferably > 1.2, wherein the metal oxide is selected from the group diethyl zinc, zinc acetate, triisopropyl titanate, tetraisopropyl titanate, cerium-β-diketonate, and cerammonium nitrate, 4. a covering layer, wherein the covering layer is formed of a silicon-based precursor having an element gradient in the oxygen concentration and/or carbon orhydrocarbon concentration, wherein the oxygen content of the cover layer close to the UV light-absorbing layer is less than on the opposite side of the cover layer and the carbon content close to the UV light-absorbing layer greater than on the opposite side of the cover layer, which is characterised by an excellent abrasion protection and a long-term resistance to ageing.
