发明名称 NOVEL POLYIMIDE PRECURSOR COMPOSITION, USE THEREOF AND PRODUCTION METHOD THEREOF
摘要 An object of the present invention is to provide a polyimide precursor composition that can be cured at low temperatures (250° C. or lower), while having a low viscosity even at a high concentration, and a method of producing the same. Another object of the present invention is to provide a polyimide coating film obtained from the polyimide precursor composition and having good physical properties, and a method of producing the same. Furthermore, another object of the present invention is to provide a photosensitive resin composition containing the polyimide precursor composition, and a method of producing the same. These objects can be achieved by the polyimide precursor composition containing an imidized tetracarboxylic acid having a specific structure and a diamine having a specific structure.
