摘要: Provided are a multilayer polyimide film that hardly suffers from the peeling of the layers from each other or the clouding of a space between the layers (turning white in color) during heating at a high temperature and a flexible metal-clad laminate using such a multilayer polyimide film. This object can be attained by a multilayer polyimide film having a thermoplastic polyimide layer on at least one side of a nonthermoplastic polyimide layer, wherein at least 60% of the total number of moles of an acid dianhydride monomer and a diamine monomer that constitute the thermoplastic polyimide is the same type of monomer as at least one type of acid dianhydride monomer and at least one type of diamine monomer that constitute the nonthermoplastic polyimide.

摘要: A laminate having good appearance, which avoids such a problem that end waviness is produced in the laminate during lamination, thus making it impossible to fix the laminate in the process for formation of a circuit pattern. A method of producing a laminate is disclosed which comprises continuously laminating a heat-resistant film having thermal fusibility with a metallic foil, characterized in that the temperature of the ends of the laminate is the same as or higher than that of the center portion in the cooling process after lamination.
