Abstract (en)

[origin: EP2082875A1] A lithographic printing plate precursor includes a support and an image-recording layer an unexposed area of which can be removed after imagewise exposure by supplying printing ink and dampening water or supplying a gum solution, wherein a betaine compound represented by the following formula (I) or (II) is contained in the image-recording layer or in a layer provided between the support and the image-recording layer: wherein R 1 to R 3 each independently represents an alkyl group having from 1 to 5 carbon atoms, an alkenyl group, an alkynyl group, a cycloalkyl group or an aryl group, each of which groups may be substituted with a hydroxy group or an amino group, Z represents an alkylene group having from 1 to 4 carbon atoms, which may be substituted with a hydroxy group, or at least two of R 1 to R 3 and Z may be combined with each other to form a heterocyclic ring.
