<p>PURPOSE:To make surface smoothness excellent and to increase adhesive force with a metal foil by providing a solventless liq. thermosetting resin compsn. layer wherein the wt. ratio of the ingredients is smaller than the wt. ratio of the compsn. ingredients between a laminated body of base materials impregnated with a solventless liq. thermosetting resin compsn. and a metal foil and heat-curing the compsn. layer. CONSTITUTION:In a laminate prepd. by laminating metal foils on one or both faces of a laminated body of base materials impregnated with a solventless liq. thermosetting resin compsn. (I1) wherein an epoxy resin (A1), a curing agent (A2) for the epoxy resin, a resin (B1) with a polymerizable unsatd. group, a polymerizable vinyl monomer (B2) and a polymn. initiator (B3) are incorporated and non-polymerizable solvent is not incorporated and heat-curing, a layer consisting of a solventless liq. thermosetting resin compsn. (I2) wherein (A1), (A2), (B1), (B2) and (B3) are incorporated, but non-polymerizable solvent is not incorporated and the wt. ratio of these ingredients [(B1)+(B2)+(B3)]/(A1)+(A2)] is smaller than the wt. ratio of the corresponding ingredients of the solventless liq. thermosetting resin compsn. (I1), is provided between the laminated body and the metal foil and is heat-cured.</p> |
