(57) [Summary] [Purpose] A method for producing a polyamide resin, which has a large molecular weight, exhibits good heat resistance and flexibility in its film, and whose composition can be directly used for paints, adhesives, etc., and its production. A polyamide resin and a polyamide resin film obtained by the method are provided. [Structure] A polyamide resin intermediate obtained by reacting a diisocyanate (A) with a dicarboxylic acid and / or tricarboxylic anhydride (B) in a nitrogen-containing aprotic solvent, and an epoxy resin (C) And a polyamide resin and a polyamide resin film obtained by the method. |
