Abstract

To provide a color-forming composition and a color-forming curable composition each of which forms high color upon exposure to light and has small fading after the color formation, and a lithographic printing plate precursor capable of undergoing on-press development, which forms high color upon exposure to light, which has a high plate inspection property, and which provides a lithographic printing plate of high printing durability. A color-forming composition containing (A) a radical generator, (B) a compound represented by formula (1) shown below and (C) a binder polymer, a color-forming curable composition further containing (E) a polymerizable compound, and a lithographic printing plate precursor comprising an image-recording layer containing the color-forming curable composition. wherein, in the formula (1), R 1 represents a group which reacts with a radical generated from the radical generator (A) to be released and forms a dye after the release, and T represents a nitrogen-containing hetero ring.

Description

technical field [0001] The present invention relates to a color-developing composition exhibiting excellent color development under exposure, a color-developing curable composition, a lithographic printing plate precursor in which the color-developing curable composition is applied to an image recording layer, and a lithographic printing plate precursor using the same Including plate-making methods of on-press development, and new chromogenic compounds. Background technique [0002] A lithographic printing plate generally includes an oleophilic image portion that receives ink during printing, and a hydrophilic non-image portion that receives dampening water. Lithographic printing is: using the property that water and oily ink repel each other, the lipophilic image part of the lithographic printing plate is used as the ink receiving part, and the hydrophilic non-image part is used as the wet water receiving part (ink non-receiving part). ), a method in which a difference in ...
