COLORED POLYIMIDE FILM AND METAL LAMINATE STRUCTURE INCLUDING THE POLYIMIDE FILM

摘要

A colored polyimide film includes a polyimide polymer obtained by reacting diamine monomers with dianhydride monomers, wherein the diamine monomers are oxydianiline (ODA) and phenylene diamine (PDA) monomers, and the dianhydride monomers are pyromellitic dianhydride (PMDA); a matting agent composed of polyimide particles; and one or more color pigments. The polyimide films described herein have low gloss, low transparency, and a low coefficient of thermal expansion.
