METHOD FOR PRODUCING POLYIMIDE LAMINATE, AND POLYIMIDE LAMINATE

摘要

The present invention relates to a method for producing a polyimide laminate, comprising:
forming a thin film of a polyamic acid solution composition on a substrate; and
heating the obtained laminate of the substrate and the thin film of the polyamic acid solution composition at least at a temperature of from more than 150°C to less than 200°C for 10 minutes or more, and then heating the laminate at the highest temperature of from 400°C to 550°C, to form a polyimide layer having a thickness of less than 50 µm on the substrate.
