【Task】 The object of the present invention is a poly (amide acid-imide) resin that is excellent in transparency, can be chemically modified, and does not substantially generate siloxane-based outgas, and is derived from the resin. It is an object of the present invention to provide a poly (amide acid-imide) resin having excellent flexibility. [Solution] Use a poly (amide acid-imide) resin obtained by copolymerization reaction with a combination of a specific tetracarboxylic dianhydride, a specific aromatic diamine and a specific polyoxyalkylene diamine. [Selection] None. |
