Abstract
The present method is drawn to the creation of fast-drying, photo-quality images with an ink-jet inks. The method comprises the steps of providing a inorganic porous media substrate, providing an aqueous ink-jet ink comprising an ink vehicle and an effective amount of a metallized dye having at least one heterocyclic nitrogen ring and an azo bond wherein the heterocyclic nitrogen is chelated or complexed to a transition metal, and jetting the aqueous ink-jet ink onto the inorganic porous media substrate.
