AQUEOUS POLYIMIDE PRECURSOR SOLUTION COMPOSITION AND METHOD FOR PRODUCING AQUEOUS POLYIMIDE PRECURSOR SOLUTION COMPOSITION

摘要

The present invention relates to a method for producing an aqueous polyimide precursor solution composition, comprising reacting a tetracarboxylic dianhydride and a diamine, which has a solubility in water at 25°C of 0.1 g/L or more, in the presence of an imidazole, using water as a reaction solvent to provide an aqueous polyimide precursor solution composition, and also relates to an aqueous polyimide precursor solution composition.
