Abstract
The present disclosure relates to an active energy ray curable inkjet ink for use in a single pass printing inkjet system, the inkjet ink containing a colorant, a monomer and at least one initiator, wherein the sum of the integrated value(s) of absorbance across wavelengths from 380 to 410 nm of the initiator(s) is at least 35, and 0.02≦amount of initiator/amount of monomer≦0.50 (weight ratio) is satisfied. The disclosure also relates to an ink set including the ink. The present disclosure is able to show printed articles that exhibit no wrinkling or tack, excellent color reproducibility, and reduced amounts of residual components within the cured film of printed articles, while offering high productivity, and can also show an active energy ray-curable inkjet ink cured film which has a low residue ratio and is of low-odor, while exhibiting similar print quality and productivity to existing printing systems.
