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), R1 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.
提供一种成色组合物和一种成色固化组合物,每种成色组合物在光照下都能形成较高的颜色,并且在成色后褪色较小,还提供一种能够进行印刷机显影的平版印刷版前体,这种平版印刷版前体在光照下能形成较高的颜色,具有较高的印版检查性能,并能提供具有较高印刷耐久性的平版印刷版。
一种成色组合物,含有(A)自由基发生器、(B)由下式(1)表示的化合物和(C)粘合剂聚合物;一种成色固化组合物,进一步含有(E)可聚合化合物;以及一种平版印刷板前体,包括含有成色固化组合物的图像记录层。
其中,在式 (1) 中,R1 代表与自由基发生器 (A) 生成的自由基反应并在释放后形成染料的基团,T 代表含氮杂环。
