Process for producing metal-polyimide composite article.

摘要

The present invention provides a process for producing a metal (2)-polyimide (3) composite material such as a wiring board. In production thereof, deterioration of polyamide film (3) due to oxidation during imidization of a polyimide precursor in contact with metal (2) such as copper or silver can be prevented. The present invention is characterized by using a polyimide precursor having an acidic functional group which is masked. Examples of the polyamide precursor are polyamic acid epoxy adducts, amido polyamic acids, silylated polyamic acids, etc.
