Ink composition
Abstract:
An ink composition is provided that includes compound A represented by Formula (I) below, compound B represented by Formula (II) below, and a polymerizable compound, wherein, in Formula (I), X denotes O, S, or NRa, n1 denotes 0 or 1, Ra, R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 independently denote a hydrogen atom or a monovalent substituent, and two of R1, R2, R3, R4, R5, R6, R7, and R8 that are adjacent may be linked to each other to form a ring, and in Formula (II), X denotes O, S, or NRb, n2 denotes 0 or 1, Rb, R11, R12, R13, R14, R15, R16, R17, and R18 independently denote a hydrogen atom or a monovalent substituent, and two of R11, R12, R13, and R14 that are adjacent may be linked to each other to form a ring. There is also provided an inkjet recording method comprising (a) a step of discharging the ink composition onto a recording medium, and (b) a step of curing the ink composition by irradiating the discharged ink composition with actinic radiation.
