主权项 1. A photopolymerizable inkjet ink, comprising as a photopolymerizable monomer: (a) diethylene glycol dimethacrylate; and (b) at least one polyfunctional monomer with three or more functional groups selected from the group consisting of caprolactone-modified dipentaerythritol hexaacrylate and ethylene oxide-modified trimethylolpropane trimethacrylate, wherein the photopolymerizable inkjet ink is negative for skin sensitization, and wherein an amount of the (a) component in the ink is 10% by mass to 95% by mass with respect to the entire photopolymerizable monomer, and an amount of the (b) component in the ink is 5% by mass to 90% by mass with respect to the entire photopolymerizable monomer.
