| titleOfInvention | Method for producing transparent polyimide film |
| abstract | Disclosed is a method for producing a transparent polyimide film that is excellent in dimensional stability, transparency, and heat resistance and is useful as a heat-resistant transparent resin substrate material that can be easily peeled off from a supporting substrate to obtain a thin polyimide film. . The polyimide precursor is one or two selected from 2,2'-bis (trifluoromethyl) -4,4'-diaminobiphenyl and 2,2'-dimethyl-4,4'-diaminobiphenyl. It is obtained by reacting a diamine containing a seed with an acid dianhydride containing 1,2,3,4-cyclobutanetetracarboxylic dianhydride, and the thermal expansion coefficient of the polyimide film is 45 ppm / The transparent polyimide film manufacturing method is characterized in that the light transmittance is 5% or less for a light beam having a light transmittance of 308 nm and 70% or more for a light beam having a wavelength of 400 nm.
