[PROBLEMS] To provide: a resin-coated aluminum alloy sheet which has a chromium-free surface treatment layer and has a coating formed by coating fluid application or by applying an organic resin, and which is excellent in adhesion and corrosion resistance even after formation by severe processing such as, e.g., drawing; and a formed object. [MEANS FOR SOLVING PROBLEMS] The resin-coated aluminum alloy sheet comprises: an aluminum base having a surface treatment coating film on at least one side thereof; and an organic resin coating film layer formed on the surface of the aluminum base. It is characterized in that the surface treatment coating film contains zirconium in an amount of 2-100 mg/min terms of metal atom amount and contains at least any one of polyitaconic acid, monosaccharide alcohols, and disaccharide alcohols as an aluminum-ion-trapping agent. The formed object may be a can body, can lid, etc. |
