Beschreibung
Zusammenfassung:	Provided is a radiation-curable ink suitable for preparing a conductive biological model that contains water, can retain the water for a long period of time, and has a long period of use and to provide a three-dimensional object that is suitable for the biological model, contains water, and can maintain conductivity for a long period of time.A radiation-curable ink includes a first liquid phase including a radiation-curable hydrophobic polymerizable compound, and a second liquid phase including at least one compound selected from the group consisting of water, an aqueous polymerizable compound, an aqueous polymer, and an aqueous non-polymerizable compound, wherein the second liquid phase is emulsified and dispersed in the first liquid phase. A three-dimensional object is formed by curing the radiation-curable ink, in which a third liquid phase derived from the second liquid phase and including at least one compound selected from the group consisting of water, an aqueous polymerizable compound, an aqueous polymer, and an aqueous non-polymerizable compound is dispersed as a sea-island structure in the continuous phase of the hydrophobic cured product formed by curing the first liquid phase, and the water content of the third liquid phase is 1% by weight or more.
