Water Fast Ink Jet Print Using an Acrylic /Nano-Silver Ink

A color ink jet printing with ‎improved water fastness property ‎was produced using an ‎acrylic/nano silver resin in the ‎ink’s formulation. Introduced resin ‎was a nano-composite ‎‎(acrylic/nano silver) emulsion ‎which was prepared via mini-‎emulsion polymerization of ‎acrylate monomers in the presence ‎of silver nano-particles. The water ‎fastness properties of the prints ‎were assessed by the ASTM ‎‎/F2292-03 water fastness test ‎standard. The results indicated ‎that nano composite resin ‎increased water fastness property ‎of the printed paper and provided ‎a water insoluble printed image on ‎the paper. Furthermore, by ‎introducing acrylic/nano-silver ‎resin in the ink formulation, the ‎hue of printed image was darker ‎than plain acrylic resin. ‎
