INK JET INK AND METHOD FOR MANUFACTURING PRINTED OBJECT

摘要

PROBLEM TO BE SOLVED: To optimally adjust the viscosity of a polymerization-type ink jet ink including an acceptor monomer and a donor monomer by inhibiting the generation of deposits and to enhance the adhesiveness of a cured ink (image) to a recording medium.SOLUTION: The ink jet ink includes an electron-accepting monomer (A) including maleimide and either or both of a maleic acid ester and a fumaric acid ester and an electron-donative monomer (D) including vinyl ether. The ratio of the functional group number of the electron-donative monomer (D) with respect to the functional group number of the electron-accepting monomer (A) is 40/60-60/40; the ratio of the functional group number of the maleimide with respect to the sum of the respective functional group numbers of the maleic acid ester and fumaric acid ester is 65/35-90/10; the ratio of the functional group number of monofunctional monomers with respect to the sum of the respective functional group numbers of the electron-accepting monomer (A) and electron-donative monomer (D) is 10%-45%.
