Metal-cyanine dye having axial ligands which reduce visible absorption
摘要:
The present invention provides an IR-absorbing metal-cyanine dye, said metal having at least one axial ligand bound thereto, wherein said axial ligand comprises a moiety suitable for reducing intermolecular interactions between adjacent dye molecules, thereby minimizing absorption of visible light.Dyes of this type are especially suitable for use in netpage and Hyperlabel systems.
