<P>PROBLEM TO BE SOLVED: To provide a polymerizable composition which is polymerized and cured with high sensitivity by exposure to laser light or the like, has excellent storage stability and development stability, and is useful for a recording layer of a negative lithographic printing plate original version, and to provide an image recording material using the same composition. <P>SOLUTION: The polymerizable composition contains (A) a radical-crosslinkable alkali-soluble polymer having both a styrene group and an alkali-soluble group on a side chain, and a radical-crosslinkable alkali-soluble polymer having both a (meth)acrylic group and an alkali-soluble group on a side chain. Preferably, the polymerizable composition further contains (B) a polymerizable compound and (C) a polymerization initiator. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
