Abstract

Provided are: a chromogenic composition and a chromogenic curable composition which highly assume a color upon exposure to light and suffer little color fading after the coloring; and an on-press developable, lithographic printing plate precursor which highly assumes a color upon exposure to light, has high inspectability, and gives a lithographic printing plate having high printing durability. The chromogenic composition is characterized by comprising (A) a radical generator, (B) a compound represented by formula (1), and (C) a binder polymer. The chromogenic curable composition is characterized by further containing (E) a polymerizable compound. The lithographic printing plate precursor has an image-recording layer which comprises the chromogenic curable composition. (In the formula, R1 represents a group which reacts with a radical generated by the radical generator (A), is released, and then becomes a colorant; and T represents a nitrogenous heterocycle.)

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 ...
