| description | A donor element for thermal transfer comprising a support having on one side thereof a fluorescent europium complex dispersed in a polymeric binder. In a preferred embodiment, the complex has the formula: wherein: D is a substituted or unsubstituted, aromatic, 5- or 6-membered carbocyclic or heterocyclic moiety; and J is -CF3, -CH3, -CH2F or -CHF2. In another preferred embodiment, the europium atom may also have attached thereto at least one monodentate ligand with an electron-donating oxygen or nitrogen atom or at least one bidentate ligand with two electron-donating oxygen, nitrogen or sulfur atoms atoms capable of forming a 5- or 6-membered ring with the europium atom. |
