    摘要: A surface-treated metal material, comprising: a metal material, and a coating film disposed on the surface thereof, the coating film containing (A) an organic resin having a glass transition temperature of more than 35° C. and not more than 100° C., and (B) an organic resin having a glass transition temperature of more than 100° C. and not more than 250° C.; wherein the difference between the glass transition temperatures of the organic resins (A) and (B) is 50° C. or more. There are provided a surface-treated metal material having a coating film which contains no environmental load substance such as hexavalent chromium, and is particularly excellent in scratch resistance, press formability, and corrosion resistance after the shape processing thereof, and also a process for producing such a surface-treated metal material.
