<P>PROBLEM TO BE SOLVED: To provide a photosensitive composition having high sensitivity to oscillation wavelengths of an inexpensive short wavelength semiconductor laser, excellent in developing property, and storage stability, and useful as a photosensitive layer of a planographic printing plate precursor for scanning exposure. <P>SOLUTION: The photosensitive composition contains (A) a sensitizing dye having a solubility of 100 (mg/l) or more with an alkali developing solution at 25°C (pH=11.95), (B) an initiator compound that can produce a radical, acid or base, and (C) a polymerizable compound that reacts with at least one of radicals, acids and bases. <P>COPYRIGHT: (C)2007,JPO&INPIT |
