Beschreibung
Zusammenfassung:	The present invention relates to a method for treatment of at least one surface of a substrate, wherein said surface is at least partially made of aluminum and/or an aluminum alloy, comprising at least a step of contacting said surface with an acidic aqueous composition (A), said acidic aqueous composition (A) comprising one or more metal compounds (M) selected from the group of titanium compounds, zirconium compounds and hafnium compounds and one or more linear polymers (P) containing (m1) Ν,Ν-dimethyl (meth)acryl amide, (m2) vinylphosphonic acid, and (m3) (meth)acrylic acid in form of their polymerized monomeric units, the one or more linear polymers (P) being comprised in the acidic aqueous composition (A) in an amount of 50 to 5000 ppm, based on the total weight of the acidic aqueous composition, to a corresponding acidic aqueous composition (A) as such, to a master batch to produce such acidic aqueous composition (A), to the use of the acidic aqueous composition (A) for treating surfaces and to substrates comprising the thus treated surfaces. La présente invention concerne un procédé de traitement d'au moins une surface d'un substrat, ladite surface étant au moins partiellement constituée d'aluminium et/ou d'un alliage d'aluminium, comprenant au moins une étape consistant à mettre en contact ladite surface avec une composition aqueuse acide (A), ladite composition aqueuse acide (A) comprenant un ou plusieurs composés métalliques (M) choisis dans le groupe des composés de titane, des composés de zirconium et des composés d'hafnium et un ou plusieurs polymères linéaires (P) contenant (m1) un N,N-diméthyl(méth)acryl amide, (m2) de l'acide vinylphosphonique et (m3) de l'acide (méth)acrylique sous la forme de leurs unités monomères polymérisées, le ou les polymères linéaires (P) étant compris dans la composition aqueuse acide (A) selon une quantité s'inscrivant dans la plage de 50 à 5 000 ppm, sur la base du poids total de la composition aqueuse acide, pour une composition aqueuse acide correspondante (A) en tant que telle, pour un mélange maître servant à produire une telle composition aqueuse acide (A), pour l'utilisation de la composition aqueuse acide (A) pour traiter des surfaces et pour des substrats comprenant les surfaces ainsi traitées.
