1. A cationic polymerization ink that can be hardened by cationic polymerization, comprising monomers, wherein:

  • the monomers include an epoxy monomer and an oxetane monomer, the epoxy monomer being a monomer having an epoxy group as a functional group, and the oxetane monomer being a monomer having an oxetane group as the functional group;

    the monomers include a monofunctional monomer having one functional group and a polyfunctional monomer having at least two functional groups;

    a total functional group equivalent weight is not less than 130 and not greater than 144, the total functional group equivalent weight being a total of a functional group equivalent weight of the monofunctional monomer and a functional group equivalent weight of the polyfunctional monomer; and

    a ratio of the functional group equivalent weight of the polyfunctional monomer to the total functional group equivalent weight being not less than 23 percent and not greater than 38 percent.
