Abstract:
The present invention provides a lithographic printing plate precursor which exhibits satisfactory ink cleanup and restart toning characteristics during printing.Disclosed is a lithographic printing plate precursor comprising a substrate having thereon in order an interlayer containing a copolymer comprising K units and L units, and an image-forming layer, wherein said K unit is derived from a monomer of the formula I: wherein R1 represents a hydrogen atom, a C1-22 linear, branched or cyclic alkyl group, a C1-22 linear, branched or cyclic, substituted alkyl group, a C6-24 aryl group or substituted aryl group, wherein the substituent is selected from a C1-4alkyl group, an aryl group, a halogen atom, a keto group, an ester group, an alkoxy group, or a cyano group; Y represent a single bond, or a C1-22 linear, branched or cyclic alkylene; or CH2═CHPO(OH)2; and said L unit is derived from a monomer of the formula II: CH2═CRCONH2 (II) wherein R is H or CH3, and said K units are present from more than 3% and less than 40% and said L units are present from more than 60% and less than 97% in the copolymer.
