[Problem] To provide a negative image recording material capable of forming a lithographic printing plate in which ablation at the time of laser scanning exposure is suppressed, the strength of the formed image portion is high, and the printing durability is excellent. The purpose is to: SOLUTION: The heat-mode-compatible negative image recording material of the present invention has (A) a side chain having at least one of groups represented by the following general formulas (1) to (3), A polyurethane resin soluble in an aqueous solution, (B) a photothermal conversion agent, and (C) a compound that generates a radical by heat mode exposure to light having a wavelength that can be absorbed by the photothermal conversion agent, An image can be formed by heat mode exposure. [In general formulas (1) to (3), R 1 to R 11 each independently represents a monovalent organic group. X and Y are Each independently represents an oxygen atom, a sulfur atom, or -N (R 12 ) —, wherein Z is an oxygen atom, a sulfur atom, —N (R 13 )-or a phenylene group which may have a substituent. ].
