The present invention provides a surface treatment coating layer containing a polycarboxylic acid polymer and a zirconium compound on at least one surface of a metal plate, and a coating film containing a polyester resin, a phenol resin and an acid catalyst on the surface treatment coating layer. The surface-treated metal plate has excellent dent resistance that can be applied to acidic beverages and the like, and is used in a high-temperature / humid environment such as sterilization treatment. The organic resin coating layer formed on the coating film is a non-chromium surface-treated metal plate that can provide a can body and a can lid having excellent hot water adhesion without fear of peeling off. |
