A heat mode type negative image recording material is providednwhich comprises (A) a polymer compound that is insoluble in water but isnsoluble in an alkali aqueous solution and has at least one of groupsnrepresented by general formulae (1) to (3) on a side chain; (B) anphotothermal conversion agent; and (C) an onium salt compound formingnradicals by heat mode exposure with light that is capable of beingnabsorbed by said photothermal conversion agent (B), said heat mode typennegative image recording material being capable of recording an image bynheat mode exposure. The general formulae are defined in thenspecification. |
