The present invention relates to a cathodically depositable aqueous electrodeposition coating composition comprising at least one cathodically depositable polymer and at least one alkoxylated polyethyleneimine. The invention also relates to a method for at least partially coating an electrically conductive substrate by cathodic electrodeposition coating of the previously mentioned electrodeposition material. Furthermore, the present invention relates to the use of at least one alkoxylated polyethyleneimine for improving the edge corrosion protection of an electrically conductive substrate having a baked coating film obtained from the aforementioned cathodically depositable aqueous electrodeposition coating composition. 本发明涉及一种可阴极沉积的水性电沉积涂料组合物，其包含至少一种可阴极沉积的聚合物和至少一种烷氧基化聚乙烯亚胺。本发明还涉及一种通过先前提及的电沉积材料的阴极电沉积涂覆至少部分地涂覆导电基材的方法。此外，本发明涉及至少一种烷氧基化聚乙烯亚胺用于改善导电基材的边缘腐蚀防护的用途，所述导电基材具有由上述可阴极沉积的水性电沉积涂料组合物获得的烘烤涂膜。
