Negative image-recording material and cyanine dye

摘要

The invention provides a negative image-recording material for heat-mode exposure systems, which comprises (A) an IR absorbent including cyanine dye having an electron-withdrawing group or a heavy atom-containing substituent in at least one terminal aromatic ring, (B) a radical generator and (C) a radically-polymerizable compound, and which is imagewise exposed to IR rays for image formation thereon.
