Beschreibung
Zusammenfassung:	The invention relates to a method for coating metallic surfaces with an aqueous composition as a solution or dispersion, in which the composition contains a) at least one phosphate, b) at least 0.1 g/l of at least one titanium or/and zirconium compound, c) at least one complexing agent, d) cations of aluminium, chromium(III) or/and zinc or/and at least one compound having a content of aluminium, chromium(III) or/and zinc and e) 1 to 500 g/l of at least one acid-tolerant, cationic or nonionic organic polymer/copolymer, based on the content of the solids and active ingredients of these additives. La invención se relaciona con un método para recubrir superficies metálicas con composiciones acuosas como una solución o dispersión, en el cual la composición contiene a) al menos un fosfato, b) al menos 0.1 g/l de al menos un compuesto de titanio y/o circonio, c) al menos un agente complejante, d) cationes de aluminio, cromo (III) y/o zinc y/o al menos un compuesto que tiene un contenido de aluminio, cromo (III) y/o zinc y e) 1 a 500 g/l de al menos un polímero/copolímero orgánico, catiónico o no jónico, tolerante al ácido, basándose en el contenido de sólidos y los ingredientes activos de estos aditivos.
