ABSTRACT:
A surface treatment aqueous solution is provided which is superior in corrosion resistance and coating adhesiveness as well as in ability of inhibiting the production of precipitate. A tinned DI can, which has been degreased, is conversion coating processed in a treatment bath filled with a surface treatment aqueous solution containing at least phosphate ions, organophosphonate compound and tin ions with a pH value of 5 or less. After the conversion coating, the DI can is washed with water and dried. A preferable organophosphonate compound is one in which a phosphorus atom constituting a phosphonate group is bonded to a carbon atom.
