In formula (2), R 4 represents a hydrogen atom or a methyl group, J represents -CO-, -COO-, etc., R 5 represents a hydrogen atom, an alkyl group, an aryl group, etc., W represents a single bond or a bivalent linking group, and P represents a heterocyclic residue having a hetero ring contained in an organic pigment.
Abstract:
The invention provides an ink composition comprising a polymerization initiator, a (meth)acrylate having a double bond with a carbon atom having an sp 3 hybrid orbital at an ± position, and a colorant; an ink jet recording method using the ink composition; a planographic printing plate obtained by using the ink composition; and a method for producing the planographic printing plate.
Abstract:
A process for producing an inkjet ink composition is provided and includes dispersion-treating a coloring material in a non-aqueous solvent with a dispersant having no coloring material-dispersing property, the coloring material being covered with a resin insoluble in the non-aqueous solvent. An inkjet ink composition produced by the production process is provided.
