    • PURPOSE: A polyimide film is provided to be useful for a transparent conductive film, a TFT substrate, and a flexible printed circuit board as the transparency and heat resistance are excellent. CONSTITUTION: Polyimide is produced by polymerizing dianhydride monomer and diamine monomer. The diamine monomer is a mixture of 1,4-cyclohexyldiamine and 2,2'-bis (trifluoromethyl)benzidine. The dianhydride monomer is a mixture of 2,2-bis (3,4-anhydridicarboxyphenyl)hexafluoropropane and pryomellitic dianhydride. The mole ratio of (2,2-bis (3,4-anhydridicarboxyphenyl)hexafluoropropane + pyromellitic dianhydride) : (1,4-cyclohexyldiamine + 2,2'-bis (trifluoromethyl)benzidine) is 1:1. The mole ratio of (1,4-cyclohexyldiamine + 2,2'-bis (trifluoromethyl)benzidine) : 2,2-bis (3,4-anhydridicarboxyphenyl)hexafluoropropane : pyromellitic dianhydride is 1:0.2-0.8:0.2-0.8. The mole ratio of (2,2-bis (3,4-anhydridicarboxyphenyl)hexafluoropropane + pyromellitic dianhydride) : 1,4-cyclohexyldiamine : 2,2'-bis (trifluoromethyl)benzidine is 1:0.2-0.8:0.8-0.2.
