The invention relates to an ink based on near-infrared light polymerization. The method and technology of direct writing three-dimensional printing belong to the field of material processing technology area. The method is: direct writing nozzles move in three-dimensional space or stationery, the ink is squeezed out of the direct writing nozzle, receiving the near-infrared light irradiation, after curing, complete the three-dimensional object forming and curing. The solidifying time t does not exceed the ratio of near-infrared light diameter d.sub.1 and the ink extrusion speed vi, that is, t≤d.sub.1/v.sub.i. Since near-infrared light has a better medium mass penetration, can penetrate the structure during molding to promote both internal and external to a higher degree of curing, so as to achieve cross-scale structure 3D printing, and the method provided by the present invention accurately controls solidifying process of the ink and therefore achieve the DIW array 3D structure real-time curing.

An inkjet recording method contains the sequential steps of: applying an aqueous pre-coat composition to a substrate, or applying and drying the aqueous pre-coat composition to the substrate; and subsequently applying and drying an aqueous ink composition. The aqueous pre-coat composition contains at least an aggregating agent. The aqueous ink composition contains at least a pigment, a polymer dispersant, and resin fine particles. The aggregating agent is selected from a pyrolytic cation resin, an organic acid, or a multivalent metal salt. A neutralizer for the polymer dispersant is selected from an organic amine. In the step of drying the aqueous ink composition, a temperature at which the aqueous ink composition is dried is set to be equal to or higher than a pyrolytic temperature of the aggregating agent.
