NOVEL POLYIMIDE FILM AND ADHESIVE FILM WITH USING THEREOF, AND FLEXIBLE METAL-CLAD LAMINATE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a polyamide film having a function of inhibiting heat strain on materials especially when a metal layer and a polyimide film are laminated by a lamination method, an adhesive film with using the polyamide and a flexible metal-clad laminate sheet.SOLUTION: A Polyimide film obtained by imidization of a polyamic acid from a reaction of an aromatic diamine and an aromatic acid dianhydride and having a certain range of its storage elastic modulus, an adhesive film and a flexible metal-clad laminate sheet are used to attain the purpose.
