Ink jet ink for forming an infrared absorbing image, infrared absorbing image forming method, and recorded material

An ink jet ink for forming an infrared absorbing image comprising:

• an infrared absorbing material represented by Formula (1);
• resin particles;
• a water-soluble organic solvent;
• a water-soluble organic compound X1 having a melting point of 50° C. or higher and a molecular weight of lower than 3000;
• a surfactant;
• and
• water,
• wherein a content of the water-soluble organic solvent is from 10 mass % to 26 mass % with respect to a total amount of the ink jet ink,
• a content of the water-soluble organic compound X1 is from 1 mass % to 8 mass % with respect to the total amount of the ink jet ink, and
• a surface tension at 25° C. is 18 mN/m to 30 mN/m:
• wherein, in Formula (1), M+ represents a proton, a monovalent alkali metal cation, or an organic cation, L1 represents a methine chain consisting of 5 or 7 methine groups, and a methine group at a center of the methine chain has a substituent,
• each of R1, R2, R3, and R4 independently represents a hydrogen atom, an alkyl group, an aryl group, or a monovalent heterocyclic group, and
• each X independently represents an O atom, a S atom, or a Se atom.
