    摘要: Provided are an active energy ray-curable inkjet ink containing metal particles, a polymerizable compound, and a polymerization inhibitor, in which the metal particles have a specific gravity of 3 or more, in a cross section of an ink film having a thickness of 1 μm or more, which is obtained by curing a solution prepared by adjusting a content of the metal particles in the active energy ray-curable inkjet ink to 0.5% by mass, 50% by mass or more of a total mass of the metal particles is present in a region within 100 nm from a surface of the ink film to an inside of the ink film, and a surface tension of the active energy ray-curable inkjet ink is 30 mN/m or more; and an image recording method.

    摘要: Provided are: a photocurable ink composition including particles of a squarylium coloring agent represented by Formula (1) a radically polymerizable monomer, a radical polymerization initiator, and a coloring agent sensitizer, in which a volume average particle diameter of the particles of the squarylium coloring agent is 10 nm to 400 nm (in Formula (1), ring A and ring B: an aromatic ring or a heteroaromatic ring; XA, XB, GA, and GB: monovalent substituent; kA=integer of 0 to nA; kB=integer of 0 to nB; nA: an integer that is a maximum number of GA the ring A can have as its substituent; and nB: an integer that is a maximum number of GB the ring B can have as its substituent); and an image recording method.
