METHOD FOR PROVIDING A MULTILAYER COATING ON A SURFACE OF A SUBSTRATE

The present invention relates to a method for providing a multilayer coating on a surface of a sub- strate comprising the following method steps (i) providing the substrate; (ii) depositing at least one metal oxide compound onto the surface of the substrate; (iii) heat-treating the surface of the substrate such that a metal oxide is formed thereon; (iv) treating the surface of the substrate with atreatment solution comprising at least one nitrogen containing polymeric treatment additive; (v) treating the surface of the substrate with an activation solution; and (vi) treating the surface of the substrate with a metallising solution such that a metal or metal alloy is deposited thereon. The invention further concerns the use of treatment additives as enhancer for the metal deposition. 本发明涉及在衬底表面上提供多层涂料的方法，其包含以下方法步骤：(i)提供所述衬底；(ii)将至少一种金属氧化物化合物沉积于所述衬底的所述表面上；(iii)热处理所述衬底的所述表面，使得在其上形成金属氧化物；(iv)利用包含至少一种含氮聚合物处理添加剂的处理溶液处理所述衬底的所述表面；(v)利用活化溶液处理所述衬底的所述表面；和(vi)利用金属化溶液处理所述衬底的所述表面，使得在其上沉积金属或金属合金。本发明进一步关于处理添加剂作为用于金属沉积的增强剂的用途
