Beschreibung
Zusammenfassung:	An ink composition comprising:a rare-earth complex containing one kind of trivalent rare-earth ion selected from the group consisting of Eu3+, Tb3+, Sm3+, Er3+, Pr3+, Ho3+, Tm3+and Dy3+, and a specific phosphine oxide ligand coordinated to the rare-earth ion, anda light-emitting material different from the rare-earth complex,wherein an absolute value of a difference between a wavelength (λ1) at which a light emission intensity of the rare-earth complex is maximum and a wavelength (λ2) at which a light emission intensity of the light-emitting material is maximum, is 50 nm or more.
