Abstract
Abstract A water-fast ink composition and method for making the same. A selected chemical dye having at least one functional group with an extractable hydrogen atom thereon (e.g. --COOH, --NH 2 , or --OH) is combined with an ammonium zirconium polymer salt (e.g. ammonium zirconium carbonate, ammonium zirconium acetate, ammonium zirconium sulfate, ammonium zirconium phosphate, and ammonium zirconium oxalate). The resulting mixture preferably contains about 0.01-5.0% by weight ammonium zirconium polymer salt and about 0.5-5.0% by weight chemical dye. Upon dehydration of the mixture, the ammonium zirconium polymer salt and chemical dye form a cross-linked dye complex which is stable and water-fast. The mixture may be dispensed onto a variety of substrates (e.g. paper) using thermal inkjet or other printing systems.
