oai:localhost:PNK-82222023-04-21T08:29:18Z Pyrene-naphthalimide Schiff base as a fluorescent pigment in water-based security ink R. S., Bhagya Kashmitha, Muthamma Dhanya, Sunil NHPY CC BY Fluorescence-based materials that are affordable and easy to use for commercial anti-counterfeiting applications are in high demand. While exploring new fluorescent pigments, a pyrene-naphthalimide Schiff base, 5-hydroxy-2-((pyren-1-ylmethylene)amino)-1H-benzo[de]isoquinoline-1,3(2H)-dione (NHPY) with yellow fluorescence under UV light was synthesized. An eco-friendly flexographic ink prepared with NHPY as the pigment was coated on a UV dull paper and further printed on security paper as well as packaging papers and boards. When exposed to UV light, the printed samples showed yellow fluorescence. The light fastness, gloss, colorimetric results, and abrasion resistance of the printed samples proved that NHPY is a suitable fluorescent pigment for security printing applications. 2023-04-21T08:29:18Z 2023-04-21T08:29:18Z 2023 Book https://link.springer.com/article/10.1007/s11696-023-02827-y https://dlib.phenikaa-uni.edu.vn/handle/PNK/8222 en application/pdf Springer |
