Provided is an imide group-containing compound solution which includes an imide group-containing compound obtained by partially hydrolyzing a polyimide molded article, a solvent, and a viscosity stabilizer and is excellent in long-term storage stability.
It is an imide group-containing compound solution including an imide group-containing compound obtained by partially hydrolyzing a polyimide molded article, a solvent, and a viscosity stabilizer. In the imide group-containing compound solution, an absorption peak derived from an imide group is observed at a wavenumber of 1,375 cm-1, an absorption peak derived from an amide group is observed at a wavenumber of 1,600 cm-1, and an absorption peak derived from a carboxyl group is observed at a wavenumber of 1,413 cm-1 in an infrared spectroscopy chart obtained by an infrared spectroscopic measurement of the imide group-containing compound and the viscosity stabilizer is an orthocarboxylic ester and a chelating agent or either one of the two.
