WIPO Patent Application WO/2015/046145
Kind Code:
A1
Abstract:
Provided is a steel sheet for containers, which has excellent adhesion to resins and corrosion resistance. This steel sheet for containers comprises: a tin-plated steel sheet wherein at least a part of the surface of a steel sheet is covered by a tin plating layer; and a coating film that is arranged on the tin plating layer-side surface of the tin-plated steel sheet. The coating film contains P, Zr, Ti and silica. With respect to the coating film, the amount of adhered P in terms of elemental metal per one surface of the tin-plated steel sheet is 1-10 mg/m2; the amount of adhered Zr in terms of elemental metal per one surface of the tin-plated steel sheet is 1-40 mg/m2; the amount of adhered Ti in terms of elemental metal per one surface of the tin-plated steel sheet is more than 0.5 mg/m2 but less than 10 mg/m2; and the amount of adhered Si in terms of elemental metal per one surface of the tin-plated steel sheet is 1-40 mg/m2.
