| 摘要 |
The present invention can provide a heat-sensitive lithographic printing plate which can be subjected to aqueous development or does not require any special treatment such as wet development and rubbing after image writing, in particular, a heat-sensitive lithographic printing plate which can be subjected to recording by a solid laser or semiconductor laser emitting infrared rays to allow direct plate making from digital data. Furthermore, the present invention can provide a heat-sensitive lithographic printing plate excellent in press life. The heat-sensitive lithographic printing plate comprises an image-forming layer containing a polymer which is capable of changing its hydrophilicity by heat and is crosslinked by crosslinking reaction.
