ABSTRACT:
A heat mode corresponding negative-type image recording material by which ablation in laser scanning when recording is suppressed, the intensity of the formed image portion can be high and a planographic plate excellent in plate life can be formed is provided. It is characterized in that it contains (A) polyurethane resin insoluble in water and soluble in an aqueous alkaline solution or a polymeric compound which has on the side chain thereof a group represented by the general formula (39) or the general formula (40) as a polymeric compound insoluble in water and soluble in an aqueous alkaline solution, (B) a radical-polymerizable compound, (C) a light-to-heat converting agent and (D) a compound generating a radical by heat mode exposure of a light of wavelength which can be absorbed by (C) a light-to-heat converting agent and image recording can be carried out by the heat mode exposure.in-line-formulae description="In-line Formulae" end="lead"?X—NH—Y— (39)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?-Z-NH—R (40)in-line-formulae description="In-line Formulae" end="tail"?
