When the temperature is lower than 0 ° C., the metal soap does not melt, the expected peelability cannot be obtained, and the metal soap sufficiently melts at a heat treatment temperature of up to 300 ° C., so that 300 ° C. or higher is unnecessary. If the temperature is too high, it becomes a steamed state and the coating material layer 3
May be carbonized.
