活性能量射线固化型喷墨油墨及油墨组
摘要：
本发明涉及活性能量射线固化型喷墨油墨以及由该油墨构成的油墨组，所述活性能量射线固化型喷墨油墨是用于单通道印刷方式的喷墨系统的活性能量射线固化型油墨，其含有着色剂、单体、以及至少1种引发剂，所述引发剂在波长380～410nm的吸光度积分值的总和为35以上，并且0.02≤引发剂量/单体量≤0.50(重量比)。根据本发明，能够提供在兼备高的生产性的同时，没有褶皱、粘性，颜色再现性优异且印刷物的固化膜中的残留成分少的印刷物，此外，能够提供具有与现有印刷等同的印刷画质、相同程度的生产性，且低残留率、低臭味的活性能量射线固化型喷墨油墨固化膜。
摘要（英）：

The present invention 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 invention also relates to an ink set including the ink. The present invention is able to provide 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 provide 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.
