摘要：PROBLEM TO BE SOLVED: To provide a method for producing a polyimide filmwhereby, in the case of using an imidation catalyst for improving the productivity of apolyimide film, the improvement in the handling of an organic solvent solution ofpolyamic acid and the reduction of a heat treatment temperature required for imidationare made consistent.SOLUTION: Provided is the method where polyamic acid is heat-treated and is imidated to produce a polyimide film made of a polyimide layer(s) of asingle layer or laminated plural layers, when the polyamic acid is imidated to form atleast one layer of the polyimide layer(s), aminomethyl phenylboronic acid is used as animidation catalyst. It is preferable that: (a) the aminomethyl phenylboronic acid has aphenylboronic acid skeleton; (b) a method group having a ternary amino group is directlycoupled to the phenylboronic acid skeleton; and (c) the ternary amino group is the oneobtained by coupling a 4 to 8C cyclic saturated hydrocarbon group or a 1 to 10Cnoncyclic saturated hydrocarbon group to a nitrogen atom.SELECTED DRAWING: None
