PROBLEM TO BE SOLVED: To provide an ultraviolet curable ink composition having a high curing (polymerization) speed, low viscosity and low toxicity. SOLUTION: Fine particles having a polymerizable functional group are contained, and examples of the fine particles include inorganic compounds, and it is preferable that the fine particles are transparent. Further, the polymerizable functional group may have one or more double bonds. By containing fine particles having a polymerizable functional group, a high polymerization rate, a low PII value, and a low viscosity could be satisfied. In addition, there is no need for a diluent solvent to reduce the viscosity. [Selection figure] None |
