▎ 摘  要

NOVELTY - Environmentally friendly anti-counterfeiting ink comprises 80-120 pts. wt. aqueous acrylic emulsion, 1-3 pts. wt. dispersant, and 5-15 pts. wt. inorganic fluorescent pigment comprising 30-50 pts. wt. particulate nano-inorganic fluorescent filler, 20-40 pts. wt. fibrous nano-inorganic fluorescent filler, and 10-15 pts. wt. flaky nano-inorganic fluorescent filler. USE - Anti-counterfeiting ink. ADVANTAGE - The ink is environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the ink involving mixing the aqueous acrylate emulsion, dispersant and inorganic fluorescent pigment at 45-65 degrees C, heat-retaining ball milling and mixing for 48-72 hours, cooling to room temperature, and discharging to obtain the product.
