紫外线固化型喷墨用油墨组合物、使用其的喷墨记录装置、喷墨记录方法、以及油墨组
Abstract:
本发明提供油墨的固化性优异且能防止喷墨记录后初期的固化膜的着色的紫外线固化型喷墨用油墨组合物、使用其的喷墨记录装置、使用其的喷墨记录方法、以及油墨组。所述紫外线固化型喷墨用油墨组合物含有通式(I)表示的单体A和光聚合引发剂，所述光聚合引发剂含有酰基氧化膦系光聚合引发剂和噻吨酮系光聚合引发剂，所述酰基氧化膦系光聚合引发剂和所述噻吨酮系光聚合引发剂的合计含量相对于该油墨组合物的总质量为8～16质量％，其中，通式(I)：CH2＝CR1-COOR2-O-CH＝CH-R3···(I)(式中，R1是氢原子或甲基，R2是碳原子数2～20的2价有机残基，R3是氢原子或碳原子数1～11的1价有机残基)。
Abstract(English):

An ink composition for ultraviolet curable ink jets including monomer A represented by a general formula (I): CH2-CR1-COOR2-O-CH-CH-R3 (I) (in the formula, 'R1' represents a hydrogen atom or methyl group, 'R2' represents a divalent organic residue having a carbon number of 2 to 20, and 'R3' represents a hydrogen atom or a monovalent organic residue having a carbon number of 1 to 11), and a photopolymerization initiator containing an acylphosphine oxide-based photopolymerization initiator and a thioxanthone-based photopolymerization initiator, in which the total content of the acylphosphine oxide-based photopolymerization initiator and the thioxanthone-based photopolymerization initiator is 8% by mass to 16% by mass with respect to the total mass of the ink composition.
