Inkjet ink, printed matters, and inkjet recording method

摘要

There is proposed an inkjet ink comprising a compound represented by the following general formula (1), a cationic photopolymerization initiator, a cationic photopolymerizable compound, and a pigment having an average particle diameter of 300 nm or less, wherein the cationic photopolymerization initiator is included at a ratio of 0.5% by weight to 8% by weight based on 100% by weight of the cationic photopolymerizable compound, and the inkjet ink has a viscosity of 50 mPa.sec or less at ordinary temperature, (wherein R is a monovalent organic group having 1 to 5 carbon atoms, R₁ and R₂ may be the same or different and are individually hydrogen atom or alkyl group, alkyl sulfonyl group or alkoxy group each having 1 to 3 carbon atoms).
