Lithographic printing plate precursor

摘要

A lithographic printing plate precursor having a heat-sensitive layer on a water-receptive substrate, wherein the heat-sensitive layer comprises microcapsules containing a compound having a thermally reactive functional group, and the light-sensitive layer or a layer adjacent to the light-sensitive layer contains a compound capable of acting as a co-reactant in thermal reaction of the compound having a thermally reactive functional group in a state contained in other microcapsules.
