Effect of Resin on the Property of the Fluorescent Inkjet Ink

Digital printing ink imaging is one of main technical fields in digital printing technology development, fluorescence inkjet digital printing is provided with favorable anti-falsification, which is used widely in Securities anti-counterfeiting and labels anti-counterfeiting etc^[1]. Printings coated with fluorescence inkjet ink that emits fluorescence under using short-wave ultraviolet light excitation get more favorable anti-falsification. Green fluorescent inkjet ink is composed of phosphor, resin, solvent, assistant agent etc, resin is main one of green fluorescent inkjet ink, which has a significant implication for its property. In order to discuss resins to green fluorescent inkjet ink properties, five samples of fluorescent inkjet ink are prepared, and test various performance parameters of ink samples, such as luminous intensity, surface tension, adhesive force, aridity, and so on. The study result indicated that resins have a great influence on luminous intensity, surface tension, aridity of fluorescence inkjet ink samples, surface tension and viscosity of resins immediately impact surface tension and viscosity of fluorescent inkjet ink.
