  • Publication number: 20140275319
    Abstract: Provided is an active-energy-radiation-curable inkjet recording ink that experiences reduced repulsion when ejected onto nonabsorbent substrates, that has good curability, and that causes little color mixing between uncured coatings formed adjacent to each other by ejecting inks and can thus form fine images on nonabsorbent substrates. The present invention provides an active-energy-radiation-curable inkjet recording ink containing a pigment, a silicone acrylate, an active-energy-radiation-curable compound other than the silicone acrylate, and a radical polymerization initiator. The silicone acrylate is a particular organically modified silicone acrylate including a side chain containing a polyoxyalkylene having a (meth)acryloyl group at an end thereof. The active-energy-radiation-curable compound is a compound (E) having a (meth)acryloyl group and a vinyl ether group.
