    Abstract: A conversion coating that does not substantially diminish the luster of a metal surface on which it is coated nor impair adhesion to the surface of lacquers and printing inks commonly used on beverage containers may be provided by contacting the metal surface with an aqueous liquid composition comprising water and at least the following components: (A) a component of one or more dissolved transition metal compounds that contain zirconium and may also include titanium, provided that zirconium constitutes more than 30% of the moles of the total moles or zirconium and titanium; (B) a component of at least one dissolved compound that contains inorganically bonded fluorine and is not part of component (A); and (C) a component of dissolved organic polymer molecules.
