Abstract
A negative image recording material on which an image is formable by exposure, comprising (A) a specific polymer compound that has at least one carbon-carbon double bond in a side chain thereof and a glass transition temperature of 80° C. or more, and is soluble in an aqueous alkaline solution, (B) a light-heat converting agent, and (C) a compound that generates radicals by exposure using light of a wavelength absorbable by the light-heat converting agent. The negative image recording material may also preferably includes (D) a radical-polymerizable compound. Preferably, the (A) specific polymer compound contains at least 1.5 meq/g of the carbon-carbon double bond in the side chain thereof.
