摘要：
Disclosed is a seamless aluminum can or can lid having an adhesion property and corrosion resistance, which is produced by providing a non-chrome conversion coating film on an aluminum alloy sheet and coating the surface of the resulting product with an organic resin layer. An organic-inorganic composite surface treating layer is provided on at least one surface of an aluminum alloy sheet, and anorganic resin coating layer is formed on the surface treating layer, wherein the surface coating layer comprises a zirconium compound in an amount of 2 to 20 mg/m2 in terms of a zirconium atom, a phosphorous compound in an amount of 1 to 10 mg/m2 in terms of a phosphorous atom and an organic compound in an amount of 5 to 60 mg/m2 in terms of a carbon atom.
