发明名称 Polyimide precursor composition and use thereof
摘要 An object of the present invention is to provide (a) a polyimide precursor solution which is curable at low temperatures (not more than 200° C.) and which has excellent long-term storage stability, (b) a photosensitive resin composition, a photosensitive resin film, a thermosetting resin composition, and a polyimide insulating film, each of which is obtainable from the polyimide precursor solution and each of which is preferably usable as an insulating material for electric and electronic purposes, and (c) a printed wiring board provided with the insulating film. The above object is achievable by use of a polyimide precursor composition solution containing at least a partially imidized polyimide precursor having a urethane bond.
