  • Polyimide film incorporating a colored polyimide matting power and manufacture thereof
    Patent number: 9914841
    Abstract: A colored matting powder includes particles containing a polyimide obtained by reacting diamine and dianhydride monomers at a substantially equal molar ratio, and a pigment incorporated with the polyimide, a portion of the pigment being located at an outer surface of the particles. Moreover, a colored polyimide film is also described as incorporating the colored matting powder, and can exhibit low gloss, low transparency and good insulation.
    Type: Grant
