(57) [Summary] [PROBLEMS] A photo-crosslinkable composition, which has attracted attention in terms of the strength of a photosensitive layer among image forming techniques, has excellent film strength and storage stability of a photosensitive layer, and is particularly excellent in ultraviolet light and visible light. And a photosensitive composition and a negative-working lithographic printing plate capable of forming a lithographic printing plate material capable of directly making a plate from digital data of a computer or the like by recording using a laser beam emitting infrared light. SOLUTION: A resin containing a repeating unit corresponding to a monomer having a specific structure is contained. |
