Abstract
An oil-based ink for a printing plate by an ink jet process comprising spraying an oil-based ink comprising at least resin particles dispersed in a non aqueous carrier liquid having an electric resistance of 10,&OHgr;cm or more and a dielectric constant of 3.5 or less on a water-resistant support having a lithographically printable hydrophilic surface dropwise from a nozzle to form an image, wherein said resin particles dispersed are copolymer resin particles obtained by polymerization granulation of a solution comprising (i) and (ii): (i) at least one monofunctional monomer (A) which is soluble in a nonaqueous solvent which is at least miscible with the nonaqueous carrier liquid and becomes insoluble in the nonaqueous solvent by polymerization; (ii) at least one resin for dispersion stabilization (P) which is soluble in the nonaqueous solvent and is a polymer comprising a repeating unit, wherein a part of the polymer is crosslinked and a polymerizable double bond group which is copolymerizable with the monomer (A) is combined with only one end of at least one main chain of the polymer, and a method for preparing a printing plate by an ink jet process using the ink.
