Containing compound solution comprising an imide group-containing compound obtained by partially hydrolyzing a polyimide molded article, a solvent and a viscosity stabilizer, and the like. In an infrared spectroscopy chart obtained by infrared spectroscopic measurement of an imide group-containing compound as an imide group-containing compound obtained by partially hydrolyzing a polyimide molded article, a solvent, and an imide group-containing compound solution containing a viscosity stabilizer, the wavenumber 1375cm -1, and the absorption peak derived from an already deugi, wavenumber 1600cm -1, and the absorption peak at a wave number 1413cm -1 derived from the amide group, have the absorption peak derived from a carboxyl group, and a viscosity stabilizer , An orthocarboxylic acid ester and a chelating agent, or both. |
