Disclosed is an active energy beam curable inkjet printing ink comprising anpigment, a compound containing two or more ethylenic double bonds, a compoundncontaining one ethylenic double bond and having a molecular weight of 90 to 210,n2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1 as a first initiator, andnacylphosphine oxides as a second initiator. The ink has low viscosity, excellentnphoto-polymerizability, remarkably excellent curing property, good dispersion stability,ncauses no dissolution and swelling of ink contacting materials in a printer, and showsnexcellent discharge stability from nozzles, an excellent adherence property to anrecording medium, excellent solvent resistance and water resistance. |
