PROBLEM TO BE SOLVED: To provide a two-component ink which has no stickiness on a recording medium, especially on a nonabsorbent recording medium, after recording, exhibits an improved fixability of a colorant, is free from color mixing, and makes printing with a high image quality possible. SOLUTION: The ink composition of the two-component ink contains polymer particles having functional groups reactive with a thermal curing agent; and the reaction liquid of the ink contains a flocculant (e.g. a polyvalent metal salt) and the thermal curing agent. Thus, when the ink is printed onto a recording medium and then heated, the stickiness of image parts is eliminated; the fixability of a colorant is improved; color mixing does not occur; and the image quality is further improved. |
