Abstract

Process for applying integrated pretreatment layers to metallic surfaces, particularly the surfaces of coil metals, by treatment with a composition comprising at least one binder, crosslinker, a finely divided inorganic filler, and compounds containing at least two thioamide groups or containing one thioamide group and at least one functional group. Integrated pretreatment layer obtainable by the process.
