Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an aqueous polyimide resin dispersion excellent in dispersion stability even after long-term storage and forming a resin film excellent in adhesion to metals. SOLUTION: A polyamic acid of a degree of imidation of 0-30% is used as a dispersant. The aqueous polyimide resin dispersion is excellent in dispersion stability even after long-term storage. Further, a resin film formed from the aqueous polyimide resin dispersion is excellent in adhesion to metals. COPYRIGHT: (C)2010,JPO&INPIT
