Document Type and Number:
WIPO Patent Application WO/2015/093318
Kind Code:
A1
Abstract:
 The present invention pertains to a surface-treated steel sheet and to a method for producing the same, and is a surface-treated steel sheet which has a surface treatment layer containing fluorine and composed principally of zirconium and oxygen formed on at least one surface of the steel sheet, wherein, due to the presence of a Group II element on the surface side of the surface treatment layer, it is possible to provide a metal container having exceptional corrosion resistance and adhesion to an organic resin coating, as well as exceptional adhesion to the resin on a can outer surface, and resistance to fluorine elution.
