    Abstract: A photosensitive composition and film prepared from the same are provided. The photosensitive composition includes 100 parts by weight of polyimide, 0.25-50 parts by weight of initiator and 0.25-100 parts by weight of crosslinking agent. The polyimide is a product of a reactant (a) and a reactant (b) via a reaction. The reactant (a) consists of a first dianhydride and a second dianhydride. The molar ratio of the first dianhydride to the second dianhydride is 3:7 to 8:2. The reactant (b) includes a first diamine. The first dianhydride, the second dianhydride and the first diamine are disclosed in the specification.
