Abstract
A presensitized lithographic printing plate comprises a hydrophilic support and an image-forming layer. The image-forming layer contains microcapsules and a hydrophilic compound. The microcapsules are dispersed in the image forming layer. The hydrophilic compound is arranged outside of the microcapsules. The microcapsules comprise a core and a shell. The core comprises a polymerizable compound. The shell comprises a polymer. The polymer of the shell has adherence to a surface of the hydrophilic support.
