ABSTRACT:
The present invention provides photosensitive compositions which comprise polyimide precursors having a chemical structure selected from several specific chemical structures and/or specific amide bond density and are adjusted so that the film obtained by applying and drying the composition may exhibit a specific absorbance to light. The polyimide film obtained by heat-curing the above photosensitive composition exhibits excellent physical properties and water resistance, and has high adhesive strength to epoxy resins, inorganic materials and metals.
