Abstract
The present invention provides a resin coated seamless aluminum can and a resin coated aluminum can lid having adhesiveness and corrosion resistance by applying a non-chromium chemical conversion coated film to an aluminum alloy sheet and by applying an organic resin layer to the non-chromium chemical conversion coated film. For this end, an organic-inorganic composite surface treated layer containing 2 to 20 mg/mof zirconium compound expressed in terms of zirconium atoms, 1 to 10 mg/mof phosphorus compound expressed in terms of phosphorus atoms, and 5 to 60 mg/mof organic compound expressed in terms of carbon atoms is formed on at least one-side surface of an aluminum alloy sheet, and an organic resin coated layer is formed on the organic-inorganic composite surface treated layer.
