Formulation Design of the Blue Fluorescent Ink-Jet Ink

Abstract

Fluorescent inkjet ink was composed of solvent, resin, phosphor, assistant agent etc, solvent and resin were the main components in the fluorescent inkjet ink, which had an important effect on the luminescent property and various physical properties. In order to research and develop the fluorescent inkjet ink, formulation principle had been used to design the ingredient, and fluorescent inkjet ink samples had been prepared. The effect of different solvents and resins and mixed solvent and resin on the significant performance of the fluorescent inkjet ink had been studied, such as the viscosity, surface tension, luminous intensity, and fluorescence quantum yield. The results indicated that through the formulation design principle, formulation could be optimized to make the ink have high fluorescence intensity and physicochemical properties which could meet practical printing requirement.
