Preferred curing agent contains an isophorone diisocyanate trimer. The ink includes a diisocyanate curing agent at equal to or greater than 1% by weight and equal to or less than 20% by weight, calculated on the basis of the solid content. The base material includes a polymer having a hydroxyl group as a principal component.
