<P>PROBLEM TO BE SOLVED: To provide a curable composition which can be cured with high sensitivity by laser exposure, suppresses inhibition of polymerization by oxygen, and excels in solubility in a developer and a solvent, and a lithographic printing form original using the same. <P>SOLUTION: The curable composition comprises a polymerizable monomer represented by a general formula (1) and a polymerization initiator, wherein Q represents a substituent containing an ethylenically unsaturated group; R represents a hydrogen atom or a monovalent hydrocarbon group; R<SP>1</SP>and R<SP>2</SP>each independently represent a hydrogen atom or a monovalent hydrocarbon group; A represents a divalent linking group containing at least one ether bond or a 2-5 carbon atoms linking group; B represents a (n+1)-valent linking group containing at least one ether bond or a 2-5 carbon atoms linking group; n and m each independently represent an integer of 1-3, and when m is 1, two symbols R may be the same or different. <P>COPYRIGHT: (C)2009,JPO&INPIT |
