Abstract
The invention relates to scuff and scratch resistant multilayer structures for use in building and advertising applications comprising a metal layer and a polymeric layer made of a polymeric material, said polymeric material including at least 30 wt-% of an ionomer, the weight percentage being based on the total weight of the polymeric layer.
If compared with composite panels of the state of the art, the multilayer structure of the present invention shows an improved scuff and scratch resistance, a comparable or higher resistance against abrasion and it can be manufactured at lower costs. Furthermore, the multilayer structure of the present invention shows high adhesiveness between the polymeric layer and the metal foil, high optical transparency and can be produced by a single step manufacturing process.
