Zusammenfassung:	Provided is a UV-curable water-based ink excellent in coating film performance, especially alcohol resistance and scratch resistance. The UV-curable water-based ink includes at least a UV-curable oligomer, a colorant, and a mercapto compound, in which the UV-curable oligomer has a structural unit derived from a compound represented by the following chemical formula.(In formula (1), X is an alkylene group, Y is a (meth)acryloyl group, an allyl group, an acyl group, or a hydrogen atom, and n is an integer of 2 or more.) The UV-curable water-based ink alternatively includes a colorant and a mercapto compound, in which the UV-curable oligomer has a structural unit derived from a polyisocyanate compound (A), and the compound (A) is a compound having three or more isocyanate groups in one molecule.
