The formability of thermosetting epoxy phenolic lacquer film painted on tin coated steel sheets (TP) and chromium coated steel sheets (TFS) both with chromium oxide layer was evaluated by electric resistance of the painted steel sheets and observation of SEM. The formability of the lacquer film on TFS becomes worse with increasing coating weight of chromium, while in the case of TP, the formability improves with increasing coating weight of tin. It is considered that the formability of plating layer apparently influences the formability of the film on the plating. The corrosion resistance of the painted steel sheets in acetic acid aqueous solution was evaluated by measuring the electric resistance of the sheets. The electric resistance of the painted TFS, which is low compared with that of painted TP, decreases rapidly in the solution, while that of painted TP decreases gradually.
