Abstract
A lithographic printing plate precursor which is capable of undergoing on-press development by supplying at least one of printing ink and dampening water and includes a support and an image-recording layer, wherein the image-recording layer contains at least one of compounds represented by the formulae (1) to (3) as defined herein.
Claims11
A lithographic printing plate precursor which is capable of undergoing on-press development by supplying at least one of printing ink and dampening water and comprises a support and an image-recording layer,
- wherein the image-recording layer contains a cyanine dye, a polymerization initiator, a polymerizable compound and at least one of the compounds represented by the following formulae (1) to (2):
