SURFACE-TREATED STEEL SHEET, METHOD FOR MANUFACTURING SAME, AND CONTAINER IN WHICH SAID SURFACE-TREATED STEEL SHEET IS USED

摘要

[Problem] To provide a polyester-resin-covered metal plate and a container in which the same is used, said plate having a coating adhesiveness capable of even withstanding severe forming processing while retaining excellent decorative properties and photoluminescence. [Solution] This surface-treated steel sheet is characterized in being provided with a substrate and a surface-treated layer formed on the substrate, said layer including a Ni-Sn alloy layer that has granular or acicular morphology, and a Fe-Sn alloy layer or Sn layer disposed on another part of the Ni-Sn alloy.
