ABSTRACT:
The object of the present invention is to provide a planographic original plate which can be engraved directly according to digital signals by laser beams and which can be water-developed or can be used directly for printing without a developing process. This objective has been achieved by a planographic original plate comprising a substrate and a photosensitive layer which is supported by the substrate and which contains a polymeric compound having as a side chain at least one structural unit selected from the structural units represented by the general formulas (1) to (3).
