Claim 17:
18. The method of claim 1, wherein
the heat retaining property of the water-containing material examined by the following method is less than 0.5° C.:
8 mL and 1.1 mL of the water-containing material are introduced into respective water-containing material holders,
then, the temperature of the hot plate disposed on the metal base of the coated metal material is set to 61° C. and kept for 30 minutes,
thereafter, the temperature of the water-containing material within 5 mm from the interface between the surface treatment film and the water-containing material is measured, and
the heat retaining property of the water-containing material is evaluated using the temperature difference between the 8 mL case where the amount of the water-containing material introduced is 8 mL and the 1.1 mL case where it is 1.1 mL.
