PROBLEM TO BE SOLVED: To obtain a two-part type ink capable of eliminating the stickiness after recording in a recording medium, especially a nonabsorbing recording medium and improving the fixability and rub resistance of a colorant and even water resistance without causing color mixing and clogging and carrying out printing good in image quality. SOLUTION: This photo-setting type ink is obtained by including a high- boiling wetting agent comprising at least one of a reactive monomer, a reactive oligomer, a reactive polymer and a reactive saccharide in an ink composition in the two-part type ink and further including a polyvalent metal salt and a photo-setting agent in a liquid for aggregation. Thereby, the stickiness of an image part is eliminated when the ink receives drying 4 and ultraviolet irradiation 5 after printing 3 on a recording medium 2 to improve the fixability and rub resistance of the colorant and more improve the image quality. |
