| 摘要 |
The present invention relates to a heat-curable, cathodically depositable aqueous electrodeposition coating composition, containing… (A) 50 to 95% by weight of a polymerisation, polycondensation or polyaddition product which is water-dilutable by protonation with acid and has an average molecular weight of 200 to 20,000 and primary and/or secondary hydroxyl groups and primary, secondary and/or tertiary amino groups and… (B) 5 to 50% by weight of a water-dilutable cross-linker having cationic groups or having groups which can be converted into cationic groups by protonation with acid. |
