摘要： A process for preparing a laminate by coating the surfaces of a metal substrate that has been treated with an anchor coating agent, with a modified olefin type resin and heat-adhering the olefin resin onto the surfaces of the metal substrate. The process of this invention is characterized by applying heat-treatment to the laminate at the time of adhesion or after the adhesion in the presence of a treating agent which consists of a compound prescribed in the general formulae (1) and (2). ##STR1## The laminate prepared by this process withstands deterioration of adhesion caused by aging, particularly in an atmosphere where water is present.
