Abstract
A process for forming a polyolefin coating layer onto a surface of a metal which comprises coating an uncured epoxy resin layer onto the surface of a metal and melt-bonding a polyolefin modified with an unsaturated carboxylic acid or an anhydride thereof onto the uncured epoxy resin layer coated onto said metal surface. The coating layer has a high bonding strength and excellent water resistance, especially resistance against brine.
