▎ 摘　　要

NOVELTY - Time-sensitive fluorescent anti-counterfeiting material, comprises aggregation color-changing fluorescence material, sublimable dispersion matrix and solvent. USE - The ink is useful in distinguishing and protecting product as anti-counterfeiting material which changes stably over time (claimed). ADVANTAGE - The material can be used for time-sensitive fluorescent anti-counterfeiting ink of writing or ink-jet printing, the time-sensitive fluorescent pattern which changes stably with the time is formed, continuously changes the fluorescent material agglomeration state, gradually changes the fluorescent color along with the time, can gradually generate stable change of the fluorescent anti-counterfeiting pattern along with the lapse of time, and realizes the anti-counterfeiting protection with high safety and timeliness. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: preparing time-sensitive fluorescent anti-counterfeiting material, comprising dissolving aggregated color-changing fluorescence material in solvent, adding sublimable dispersion matrix to obtain time-sensitive fluorescent anti-counterfeiting ink; time-sensitive fluorescent anti-counterfeiting ink, prepared by time-sensitive fluorescent anti-counterfeiting material; and using method of time-sensitive fluorescent anti-counterfeiting ink, comprising coating or printing time-sensitive fluorescent anti-counterfeiting ink on the surface of the anti-counterfeiting protection product, and forming time-sensitive fluorescent pattern which changes stably with time.
