Radiation curable inkjet recording ink, and method of producing planographic printing plate using same, and ink composition, inkjet recording method, printed material, method of producing a planographic printing plate, and planographic printing plate

摘要

The invention provides an inkjet recording ink which is curable by radiation irradiation containing a colorant, a polymerizable compound, and a polymerization initiation system, wherein the polymerization initiation system contains a sensitizing dye including one or more compounds selected from compounds represented by any one of formula (XIV) and formulae (XVI) to (XXVI) and a polymerization initiator; and a method of producing a planographic printing plate to obtain a hydrophobic image by ejecting the ink onto a hydrophilic support, and by irradiating radiation. Moreover, the invention provides an ink composition containing a sensitizing dye including a specific skeleton or a sensitizing dye represented by formula (1), a polymerizable compound, and a polymerization initiator; an inkjet recording method using the same; a printed material; a planographic printing plate; and a method of producing a planographic printing plate.
