PROBLEM TO BE SOLVED: To provide a steel sheet for a vessel excellent in adhesion to resin and color fastness.SOLUTION: The steel sheet for a vessel has: a steel sheet with a tin plating layer, having a steel sheet and the tin plating layer covering at least a part of a surface of the steel sheet; and a coating film arranged on the surface on the tin plating layer side of the steel sheet with the tin plating layer. The coating film has Zr and Ti, has a coating weight of 1.0 to 40.0 mg/min terms of Zr per one face of the steel sheet with the tin plating layer, has a coating weight of 0.01 mg/mor more and less than 8.0 mg/min terms of Ti per one face of the steel sheet with the tin plating layer, and has a mass ratio between Ti and Zr (Ti/Zr) of 0.01 or more and less than 0.20, and shows an absorption peak derived from a carbonyl group (C=O) in the range of the wave number of 1,550 to 1,800 cmand an absorption peak derived from a secondary hydroxy group (CH-CH) in the range of the wave number of 1,050 to 1,150 cmin an infrared absorption (IR) spectrum of the coating film. |
