A photocurable composition is provided that includes a polymerizable compound, a photopolymerization initiator, a compound represented by Formula (I) below, and an amine compound, the photopolymerization initiator comprising an acylphosphine oxide compound and/or an α-aminoacetophenone compound
in Formula (I) above, X denotes O, S, or NR, n denotes 0 or 1, R denotes a hydrogen atom, an alkyl group, or an acyl group, R1, R2, R3, R4, R5, R6, R7, and R8 independently denote a hydrogen atom or a monovalent substituent, and two of R1, R2, R3, and R4 that are adjacent may be bonded to each other to form a ring. There are also provided a photocurable ink composition that includes the photocurable composition and a colorant, an ink composition for photocuring inkjet recording that includes the photocurable ink composition, a process for producing a photocured material that includes preparing the photocurable composition and irradiating the photocurable composition with light having a light emission peak in the range of at least 340 nm but no greater than 400 nm, and an inkjet recording method that includes discharging the ink composition onto a recording medium and irradiating the ink composition with actinic radiation.
提供了一种光固化组合物,该组合物包括可聚合化合物、光聚合引发剂、下式 (I) 所代表的化合物和胺化合物,其中光聚合引发剂包括酰基氧化膦化合物和/或 α-氨基苯乙酮化合物
在上式(I)中,X 表示 O、S 或 NR,n 表示 0 或 1,R 表示氢原子、烷基或酰基,R1、R2、R3、R4、R5、R6、R7 和 R8 独立地表示氢原子或一价取代基,相邻的两个 R1、R2、R3 和 R4 可以相互键合形成环。还提供了一种光固化墨水组合物,它包括该光固化组合物和着色剂;一种用于光固化喷墨记录的墨水组合物,它包括该光固化墨水组合物;一种用于生产光固化材料的工艺,它包括制备该光固化组合物,并用在至少340纳米但不大于400纳米范围内具有光发射峰的光照射该光固化组合物;以及一种喷墨记录方法,它包括将墨水组合物排放到记录介质上,并用阳极辐射照射该墨水组合物。
