    Abstract: PROBLEM TO BE SOLVED: To provide single component, chromium-free and surface-treating liquid having excellent storage stability which is capable of forming a film having excellent corrosion resistance, solvent resistance, and coatability after alkaline degreasing of a folded part of a steel sheet, and to provide a method for manufacturing a plated steel sheet using the surface-treating liquid, and a plated steel sheet. SOLUTION: The surface-treating liquid comprises a resin compound having a specific bisphenol skeleton, a cationic urethane resin emulsion, a silane coupling agent, an organic titanium chelate compound, a tetravalent vanadyl compound, a molybdic acid compound and water at a specified content ratio and having a pH value of 4 to 5. There are also provided a method for manufacturing a plated steel sheet using the surface-treating liquid, and a plated steel sheet. COPYRIGHT: (C)2011,JPO&INPIT
