Abstract: Provided are an ink jet recording ink containing a squarylium dye represented by Formula 1, polymerizable compounds, a dispersant, and a synergist having at least one group selected from the group consisting of a carboxy group and a sulfo group and at least one ring selected from the group consisting of an aromatic ring and a heteroaromatic ring, and an image recording method: 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, and kB represents an integer of 0 to nB. nA represents the maximum number of GAs capable of being bonded to the ring A, and nB represents the maximum number of GBs capable of being bonded to the ring B.

Abstract: Provided is an ink jet recording ink containing a near-infrared absorbing colorant represented by Formula 1, a polymerizable monomer, a polymerization initiator, and a dispersant, in which a content of the polymerizable monomer is 50% by mass or more with respect to a total amount of the ink jet recording ink, and a difference between an SP value of the polymerizable monomer and an SP value of the dispersant is 3.8 MPa1/2 to 16.0 MPa1/2. Also provided is an ink jet recording method.




The description of a ring A, a ring B, XA, XB, GA, GB, kA, and kB in Formula 1 will not be repeated.

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.
