[PROBLEMS] To provide a lithographic printing plate for scanning exposure, which is excellent in workability and economy and is suitable for a CTP system, and a lithographic printing plate precursor highly sensitive to the oscillation wavelength of an inexpensive short-wavelength semiconductor laser. I do. A naphtho [1,1] represented by the following general formula (1): 8-bc] furan-5-one derivative, a titanocene compound, and a compound that reacts with a radical or an acid and changes its physical or chemical properties to be retained.
