Presensitized lithographic plate comprising microcapsules

摘要

A presensitized lithographic printing plate comprises a hydrophilic support (1) and an image-forming layer (2). The image-forming layer (2) contains microcapsules (21) and a hydrophilic compound (22). The microcapsules (21) are dispersed in the image forming layer (2). The hydrophilic compound (22) is arranged outside of the microcapsules (21). The microcapsules (21) comprise a core (21c) and a shell (21s). The core (21c) comprises a polymerizable compound. The shell (21s) comprises a polymer. The polymer of the shell has adherence to a surface of the hydrophilic support (1).
