Abstract:
Provided is a thermal fusion-type presensitized plate comprising a support and an image recording layer, wherein: the image recording layer can form an image by infrared laser exposure; an unexposed section of the image recording layer can be removed on a printer by at least either of dampening water and a printing ink; and the image recording layer contains (1) a color development system in which the hue variation generated by the infrared laser exposure is Δa／Δb ≥ 0.6, and (2) a thermoplastic polymer particle at 70 mass % or more of the solid content of the image recording layer. The presensitized plate has excellent visibility, ablation in laser exposure is suppressed, and contamination of the dampening water and the printing ink in on-press development is suppressed. Also provided is a plate-making method using said presensitized plate.
