<P>PROBLEM TO BE SOLVED: To provide a negative image recording material which suppresses ablation in laser scanning in recording and is capable of forming a lithographic printing plate having high strength of a formed image area and excellent in printing durability. <P>SOLUTION: The negative lithographic printing plate precursor responding to a heat mode comprises (A) a high molecular compound having at least one of groups represented by formulae (1)-(3) in a side chain, insoluble in water and soluble in an alkaline aqueous solution, (B) a photothermal conversion agent, (C) an onium salt compound which generates a radical upon heat mode exposure to light of a wavelength which the photothermal conversion agent can absorb, and (D) a radically polymerizable compound, and it is capable of image recording by heat mode exposure. <P>COPYRIGHT: (C)2008,JPO&INPIT |
