Investigation on Factors Influencing Fluorescence Intensity of Red Fluorescent Inkjet Ink
Abstract:
Fluorescent intensity is an important indicator to evaluate the performances of fluorescent inkjet ink. It can be affected by many factors, such as the structure and content of fluorescent material, the polarity of solvent, the type and content of resin, optical properties of different substrates. Formulation of red fluorescent ink-jet ink was designed in the paper and ink samples were prepared to explore the impact of fluorescent material content, solvent polarity, and resin type on fluorescent intensity. Results show that: fluorescent intensity gradually increases as fluorescent material content increases, when the content reaches 1.0%, fluorescent intensity decreases; saturated solubility of fluorescent material at room temperature (25°C) is 1.6%; When propylene glycol monomethyl ether acetate (PMA): ethyl acetate: n-butyl acetate = 0.36:0.42:0.22, resin EP-609 content is 16%, fluorescent intensity reaches to the highest.
