Non-aqueous photopolymerizable inkjet ink and ink cartridge |
摘要 |
A non-aqueous photopolymerizable inkjet ink, including as a photopolymerizable monomer: (a) ethylene glycol dimethacrylate; and (b) caprolactone-modified dipentaerythritol hexaacrylate or ethylene oxide-modified trimethylolpropane tri-methacrylate, or both thereof, wherein the ink includes the (a) component by 10% by mass to 95% by mass with respect to the entire photopolymerizable monomer, and the ink includes the (b) component by 5% by mass to 90% by mass with respect to the entire photopolymerizable monomer, and wherein the ink does not include a diluting solvent. |

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. |
