Method for producing aqueous polyimide precursor solution composition |
| abstract |
A method for producing an aqueous polyimide precursor solution composition includes reacting a tetracarboxylic dianhydride and a diamine in the presence of an imidazole, using water as a reaction solvent to provide an aqueous polyimide precursor solution composition. The polyamic acid and the imidazole are dissolved in the water. A concentration of the polyamic acid is 5 to 45 wt %, The imidazole is an imidazole having two or more alkyl groups as substituents. An amount of the imidazole is 1.6 moles or more per mole of the tetracarboxylic dianhydride, and a concentration of the imidazole compound based on a sum of the imidazole compound and the water is 9.47 wt % or less. The diamine component includes a diamine having a solubility in water at 25° C. of 0.1 g/L or more. |
