<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a lithographic printing plate capable of manufacturing the lithographic printing plate with an image excellent in printing plate wear by using an inkjet recording method with a photo-polymerizable ink composition excellent in strength of the image formed by delivering an ink and curing it and adhesiveness with a substrate, and the lithographic printing plate obtained thereby. <P>SOLUTION: The method for manufacturing the lithographic printing plate is characterized in that after the photo-polymerizable ink composition comprising (a) a polymerization initiator and (b) 30-90 mass% polymerizable compound with at least three functionalities is delivered on a substrate with an ink receiving layer on the substrate with a surface roughness Ra in a range of 0.2-10 μm by an inkjet recording system, the image is formed by polymerizing and curing the delivered ink composition by light exposure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
