Abstract:
A negative image-recording material for heat-mode exposure, which is able to form images by heat-mode exposure, comprising:a polyurethane resin having at least one or more side-chain branches of the following general formulae (1) to (3), which polyurethane resin is soluble in an alkaline aqueous solution; a photo-thermal converting agent; and a compound which generates a radical through heat-mode exposure to light of a wavelength which wavelength can be absorbed by the photo-thermal converting agent. wherein R1 to R11 each independently represents a monovalent organic group; X and Y each independently represents an oxygen atom, a sulfur atom, or â€”N(R12)â€”; Z represents one of an oxygen atom, a sulfur atom, â€”N(R13)â€”, and an optionally-substituted phenylene group; R12 represents a hydrogen atom or a monovalent organic group; and R13 represents a hydrogen atom or a monovalent organic group.
