The invention discloses and provides LED photocured inkjet ink suitable for high-speed ink jetting, which does not evaporate a solvent, can reduce energy consumption, can reduce environmental pollution and is suitable for cold light source LEDs. The inkjet ink comprises the following components in parts by weight: 1-10 parts of a nanoscale pigment, 2-5 parts of an ultraviolet light absorber, 1-10 parts of a super dispersion agent, 2-10 parts of a quick initiator, 2-20 parts of a macromolecular prepolymer, 0.1-2 parts of a wetting and leveling agent, 0.1-1 part of a defoaming agent, 0.1-10 parts of an adhesion promoter, 5-10 parts of a combined monomer and 30-70 parts of a UV active diluent. According to the formula of the ink, the viscosity of the ink can be reduced, a spray head of a printer cannot be blocked, ultraviolet lights can be absorbed, curing energy can reach 130 mj / cm<2>, the curing speed of the ink can be increased, the curing time can be controlled within 5-20 seconds, and meanwhile, the transfer rate of printing pattern is improved; the LED photocured inkjet ink has long-acting antioxidative and anti-yellowing performances, high luster sensation and marresistance.
