PURPOSE:To provide a laminated plate possible to extend its application field, by improving its water resisting property which has been so far a weak point for the laminated plate prepared from plural metal plates using adhesive films of modified polyethylene. CONSTITUTION:A stainless foil 2 is laminated on at least one surface of an aluminum substrate 1 through adhesive layer 3 of a modified polyethylene synthetic resin. On the surface, facing to the adhesive layer 3, of the stainless foil 2, an aluminum vapor deposited membrane 4 or a zinc vapor deposited membrane 5 is formed. Since the aluminum substrate 1 is not in direct contact with the stainless foil 2 and each of the metals, between which layers the adhesive layer 3 is sandwiched, is either aluminum or a metal having a potential close to that of aluminum, there exist no potential difference or only a small potential difference between the metal layers. The metal plate surfaces are thereby prevented from ionization to afford a good water resisting property to the product. |
