Beschreibung
Zusammenfassung:	A radiation-curable ink jet ink composition contains polymerizable monomers A including at least one monofunctional monomer B and at least one multifunctional monomer C. The polymerizable monomers A include at least one polymerizable monomer A1 whose homopolymer has a glass transition temperature of 50° C. or more in a proportion of 20% by mass or more relative to the total mass of the polymerizable monomers A. Homopolymers of the polymerizable monomers A have glass transition temperatures whose average weighted by the proportions by mass of the individual polymerizable monomers A is 25° C. to 40° C. The amount of at least one monofunctional monomer B is 50% to 80% by mass relative to the total mass of the polymerizable monomers A. The at least one multifunctional monomer C includes a specific vinyl group-containing (meth)acrylate C1.
