Photopolymerizable inkjet ink, ink cartridge, and inkjet recording device

An ink cartridge comprising:

• a photopolymerizable inkjet ink;
• and
• a container, which houses the photopolymerizable inkjet ink,
• wherein the photopolymerizable inkjet ink comprises:
• at least one selected from the group consisting of a (meth)acrylic acid ester negative for skin sensitization and a (meth)acrylamide negative for skin sensitization;
• and
• at least one selected from the group consisting of a vinyl ether negative for skin sensitization, t-butyl methacrylate negative for skin sensitization, n-pentyl methacrylate negative for skin sensitization, and n-hexyl methacrylate negative for skin sensitization.

An inkjet recording device comprising:

• an ink cartridge;
• and
• an ink jetting unit configured to apply a stimulus to a photopolymerizable inkjet ink to make the photopolymerizable inkjet ink jet, to thereby form an image,
• wherein the ink cartridge comprises:
• a photopolymerizable inkjet ink;
• and
• a container, which houses the photopolymerizable inkjet ink,
• wherein the photopolymerizable inkjet ink comprises:
• at least one selected from the group consisting of a (meth)acrylic acid ester negative for skin sensitization and a (meth)acrylamide negative for skin sensitization;
• and
• at least one selected from the group consisting of a vinyl ether negative for skin sensitization, t-butyl methacrylate negative for skin sensitization, n-pentyl methacrylate negative for skin sensitization, and n-hexyl methacrylate negative for skin sensitization.
