[PROBLEMS] To develop with an aqueous alkali solution such as an aqueous solution of sodium hydroxide, aqueous solution of sodium carbonate, etc., and has excellent flexibility, flexibility and heat resistance as film properties after imidization by heat treatment after development. A photosensitive resin composition that exhibits long-term reliability and a dry film using the same are provided. (A) a polyimide precursor having a specific structure, (B) a compound having at least two photopolymerizable unsaturated double bonds, and (C) a photopolymerization initiator. A photosensitive resin composition. |
