<P>PROBLEM TO BE SOLVED: To provide a planographic printing plate precursor which exhibits good ink clean-up and restart toning properties during printing. <P>SOLUTION: The planographic printing plate precursor includes an intermediate layer including a copolymer including a K-unit and an L-unit and an image forming layer in this order on a substrate. The K-unit is derived from a monomer represented by formula I (wherein, R<SB>1</SB>and Y<SB>1</SB>are particularly defined) or CH<SB>2</SB>=CHPO(OH)<SB>2</SB>, and the L-unit is derived from a monomer represented by following formula (II): CH<SB>2</SB>=CRCONH<SB>2</SB>(wherein, R represents H or CH<SB>3</SB>), and the copolymer includes the K-unit of 3 to 40% and the L-unit of 60 to 97%. <P>COPYRIGHT: (C)2011,JPO&INPIT |
