Document Type and Number:
Japanese Patent JP5020068
Kind Code:
B2
Abstract:
A method for producing a polyimide film comprises the steps of: preparing a polar organic solvent solution of a polyimide precursor obtained by mixing a tetracarboxylic acid dianhydride compound and a diamine compound; adding a dehydrating agent and an imidization catalyst to the polar organic solvent solution so as to prepare a resin solution composition; and drying the resin solution composition by heating so as to imidize the resin solution composition after flowing the resin solution composition onto a support in a casting manner, wherein diethyl pyridine is used as the imidization catalyst. According to the production method, it is possible to obtain a polyimide film which is highly productive and is excellent in the film quality such as the mechanical property, the adhesive strength, and the like.
