Abstract
This invention relates to the production of composites of organic polyisocyanate plastics and metals. The metals are pretreated with certain adhesion promoters in order to increase adhesion between the metal and the plastic. The pretreated metal sheet or foil is brought into contact with the reaction mixture during the chemical reaction while the plastic is being formed.
