Abstract
The invention discloses a preparation method of a long-afterglow anti-counterfeiting leather coating with multiple stimulus responsiveness, which specifically comprises the following steps: step 1, mixing a phosphorescent molecular compound, a layered nanosheet supramolecular assembly and a water-based polymer emulsion, and magnetically stirring at room temperature to obtain a long-afterglow anti-counterfeiting leather coating agent with multiple stimulus responsiveness; and 2, preparing the long afterglow anti-counterfeiting leather coating with multiple stimulus responsiveness according to the property rights obtained in the step 1. The invention further discloses a long afterglow anti-counterfeiting leather coating with multiple stimulation responsiveness. The problems that an existing anti-counterfeiting leather preparation method is complex in preparation process, high in cost and incapable of achieving double anti-counterfeiting are solved.
