Abstract: 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.
