ABSTRACT:
There is provided by the present invention a coating formulation and thermal transfer ribbons which provide printed images which are readable by magnetic ink character recognition (MICR) devices. These formulations and ribbons minimize the use of organic solvents in employing wax, binder resin and an aqueous based ferrofluid with magnetic pigment particles. MICR readable printed images are also provided as are thermal printers which employ the ribbons.
