Abstract
Provided are an ink jet recording ink containing a polymerizable monomer (A), a polymerization initiator (B), a siloxane compound (C) which includes a main chain including a structural unit having an Si—O bond and a side chain including at least one of an ethyleneoxy unit or a propyleneoxy unit and a polymerizable group, in which a proportion of a total number of moles of the ethyleneoxy unit and the propyleneoxy unit with respect to a total number of moles of the structural unit having an Si—O bond, the ethyleneoxy unit, and the propyleneoxy unit is 30% by mole or more, and a near-infrared absorbing coloring agent (D), and an ink jet recording method.
Claims9
An ink jet recording ink comprising:
- a polymerizable monomer (A);
- a polymerization initiator (B);
- a siloxane compound (C) which includes a main chain including a structural unit having an Si—O bond and a side chain including at least one of an ethyleneoxy unit or a propyleneoxy unit and a polymerizable group, in which a proportion of a total number of moles of the ethyleneoxy unit and the propyleneoxy unit with respect to a total number of moles of the structural unit having an Si—O bond, the ethyleneoxy unit, and the propyleneoxy unit is 30% by mole or more;
- and
- a near-infrared absorbing coloring agent (D)
- wherein the near-infrared absorbing coloring agent (D) includes a squarylium coloring agent represented by Formula 1,
- in Formula 1, a ring A and a ring B each independently represent an aromatic ring or a heteroaromatic ring, XA and XB each independently represent a monovalent substituent, GA and GB each independently represent a monovalent substituent, kA represents an integer of 0 to nA, kB represents an integer of 0 to nB, nA represents an integer which is a maximum number of GA's substitutable for the ring A, nB represents an integer which is a maximum number of GB's substitutable for the ring B, XA and GA may be bonded to each other to form a ring, XB and GB may be bonded to each other to form a ring, in a case of a plurality of GA's, GA's may be bonded to each other to form a ring structure, and in a case of a plurality of GB's, GB's may be bonded to each other to form a ring structure, and
- wherein a proportion of a monofunctional polymerizable monomer in the polymerizable monomer (A) is 50% by mass or less.
