Abstract
The present invention relates to a thermosensitive lithographic printing original plate comprising a substrate, a hydrophilic layer containing a hydrophilic binder polymer, and a microcapsuled oleophilic material which forms an image area by heating; the hydrophilic binder polymer having a three-dimensional cross-link and a functional group which chemically combines with the oleophilic material in the microcapsule when the microcapsule is decomposed, and the microcapsuled oleophilic material having a functional group which chemically combines with the hydrophilic binder polymer when the microcapsule is decomposed. The thermosensitive lithographic printing original plate of the present invention is excellent in printing durability and storage property and provides prints having clear images because the plate does not collect scumming. Further, development is not required in the platemaking process so that there are no problems with waste treatment and the like. Consequently, the original plate can be practically applied not only to a light printing such as a printing in offices but also to a rotary press of newspaper, form printing and the like.
