ABSTRACT:
A method of minimizing absorption of visible light in an ink composition. The ink composition includes an IR-absorbing metal-dithiolene dye. The method includes preselecting the dye such that it includes a moiety for reducing intermolecular interactions between adjacent dye molecules. The method is suitable for use in connection with page-based interactive systems employing invisible inks.
