Abstract
To provide a coloring photosensitive composition and a lithographic printing plate precursor, ensuring that coloring stability after exposure by infrared laser exposure is good and high coloring is obtained even when exposed after the elapse of time. These can be a coloring photosensitive composition containing a microgel encapsulating (A) a polymer having a glass transition temperature of 50° C. or more, (B) a photoinitiator, and (C) an infrared absorbing dye, and a lithographic printing plate precursor having an image-recording layer containing the composition.
