Patent ID: 8796411

Claim:
A polyimide precursor composition comprising a polyimide precursor having a structure formed by reacting (i) a diamine component (A), including a fluorine-containing aromatic diamine (a1) represented by the following chemical formula (I), wherein in the formula (I), R 1 and R 2 are each independently selected from —H, —(CF 2 ) n —CF 3 , and —O(CF 2 ) n —CF 3 , wherein n is an integer of 0 or more and 7 or less, and at least one of R 1 and R 2 is a fluorine-containing group, and trans-1,4-cyclohexyldiamine (a2), with (ii) an acid dianhydride component (B) including an aliphatic tetracarboxylic dianhydride (b1) and an aromatic tetracarboxylic dianhydride (b2), and wherein the diamine component (A) includes the trans-1,4-cyclohexyldiamine (a2) in an amount of 50 mol % or more and 95 mol % or less, and wherein the aliphatic tetracarboxylic dianhydride (b1) is 3,3′,4,4′-bicyclohexyl tetracarboxylic dianhydride, and the aromatic tetracarboxylic acid dianhydride (b2) is 3,3′,4,4′-biphenyltetracarboxylic dianhydride.
