Resin-coated metal sheet
The resin-coated metal sheet is composed of: a metal sheet; a lower resin layer containing a hydrophilic copolyester, formed on at least one side of the metal sheet; and an upper resin layer containing a polyester containing a diol component composed of a diol derivative of 1 to 10% by mole of alicyclic compound and 99 to 90% by mole of ethylene glycol, and a dicarboxylic acid component consisting of terephthalic acid, formed on the lower resin layer. The sum of cyclic trimer of alkylene terephthalate existing in the upper resin layer and the lower resin layer is 0.9% or less by mass. Since the manufacture of food cans using the resin-coated metal sheet does not induce white haze phenomenon and retort blushing phenomenon on outer surface of the can even after retorting, the decorative appearance on outer surface of the can is not deteriorated.
