PROBLEM TO BE SOLVED: To provide ink for ink jet printer, which is capable of printing on an ordinary paper as well as a recycled paper and which will not generate clogging, and a printing mechanism for the ink. SOLUTION: 1. An aqueous ink contains an ultraviolet ray curing type resin prepolymer, a reaction initiator and a dye. 2. The ink is constituted of an ultraviolet ray curing type resin prepolymer, a non-aqueous dye and a reaction initiator. 3. The prepolymer and the reaction initiator are injected out of different nozzles to use them 4. The prepolymer is provided with a dye adsorbing site. 5. The aqueous ink is cured by the amount of UV less than 100 mj/cm2. 6. The aqueous ink contains a fluorine base compound. |
