ABSTRACT:
An aromatic imide polymer laminate material comprising at least one aromatic imide polymer film consisting essentially of at least one aromatic imide polymer which comprises at least 80 molar % of at least one type of recurring unit of the formula (I): ##STR1## wherein R represents a divalent aromatic radical; and at least one metallic foil which is superimposed on and directly bonded to said aromatic imide polymer film, which laminate material is produced by heat-pressing said aromatic imide polymer film superimposed on said metallic foil at 250.degree. to 600.degree. C. under a pressure of 1 to 2,000 kg/cm.sup.2 without applying a bonding agent between the polymer film and the metallic foil.
